1 POLYMER NOTIFICATION GUIDANCE
Criteria
The type of notification required under NICNAS for a polymer depends mainly on the
volume per year and the molecular weight. The type and category of polymer and the
corresponding type of notification are summarised in the table below. In broad terms, these
are as follows:
Standard notification
?all biopolymers with a volume greater than 1 tonne per year; and
? synthetic polymers with a volume greater than 1 tonne per year and a number-average
molecular weight (NAMW) less than 1000.
Limited notification
?small volume polymers (less than 1 tonne per year) and site-limited polymers (less than
10 tonne per year);
? synthetic polymers with a volume greater than 1 tonne per year and a NAMW greater
than 1000; and
? polymers used for research and development or analysis at a volume between 50 kg and 1
tonne per year.
Synthetic polymers of low concern (PLC)
?polymers which satisfy the criteria listed below. Guidance for notifiers is provided in
Appendix 12 in the NICNAS Handbook for Notifiers on the NICNAS website
www.nicnas.gov.au.
It should be noted that each batch of a particular new polymer must meet the criteria to be
eligible for notification as a PLC.
(a) Number-average molecular weight
Except for certain polyesters (see (g) below), a PLC must have a NAMW greater than 1000.
For polymers with NAMW between 1000 and 10000, the allowable low molecular weight
species (MW below 1000 and 500) for these polymers is 25% and 10% respectively provided
that the polymer has a limited content of reactive functional groups (for guidance and list of
reactive functional groups, see Appendix 12 of Handbook).
For polymers with NAMW greater than 10000, the allowable low molecular weight species
(MW below 1000 and 500) for these polymers is 5% and 2% respectively. There is no
restriction on the number of reactive functional groups in the polymer.
(b) Low charge density
A polymer has a low charge density if it is not a cationic polymer or is not reasonably
anticipated to become a cationic polymer in a natural aquatic environment (4
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
6
Certain solid materials and polymers with a low content of cationic groups are allowable as
PLCs (see guidance in Appendix 12 of Handbook).
(c) Low residual monomer content
A polymer has a low residual monomer content if the concentration of monomer in the
polymer is below its lowest concentration cut-off in accordance with the NOHSC Approved
Criteria for Classifying Hazardous Substances. That is, the polymer would not be classified
as a hazardous substance.
(d) Stability
A polymer is stable under the conditions in which it is used if it does not readily break down
by hydrolysis, thermal degradation, photodegradation, depolymerisation or any other means.
(e) Chemical composition
A PLC must contain as an integral part of its composition at least two of the atomic elements
carbon, hydrogen, nitrogen, oxygen, silicon and sulfur. There are restrictions on the content
of other elements (see guidance in Appendix 12 of Handbook).
(f) Water absorbing polymers
A water absorbing polymer with NAMW 10000 and greater cannot be a PLC.
(g) Polyesters
A polyester manufactured solely from one or more allowable reactants may be a PLC,
provided that the polymer meets the other criteria (see Appendix 12 of Handbook for list of
allowable reactants).
Notification Requirements
The data requirements for a polymer subject to a Standard Notification, a Limited
Notification or notification as a Synthetic Polymer of Low Concern are found in the
Handbook on the website. Similarly, requirements for a polymer which may be eligible for a
commercial evaluation or low volume permit are found under the appropriate heading.
Part D of the Schedule, which is specific to polymers, is required in most polymer
notification statements. In general, there are more stringent data requirements for
biopolymers than synthetic polymers. Guidance for each of the data items in the Schedule
can be found in chapter 10, SCHEDULE OF DATA REQUIREMENTS, in the Handbook on
the website.

2 PUBLICATION SUMMARY REPORT
Triglycidyl Trimellitate
Summary Report
Reference No: NA/853
Vantico Pty. Ltd. (ACN: 091 627 879) of 235 Settlement Road Thomastown VIC 3074 has
submitted a standard notification statement in support of their application for an assessment
certificate for Triglycidyl Trimellitate. The notified chemical is intended to be used as cross-
linking agent for polyester or acrylic powder coatings. Two to 15 tonnes of the notified
chemical will be imported per annum for each of the first five years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
Based on the results of studies of either the notified chemical or a structural analogue, the
notified chemical is considered to be of very low acute oral toxicity and low acute dermal
toxicity in rats. It is a slight skin irritant, a moderate to severe eye irritant and a skin
sensitiser.
The notified chemical is considered to be of low repeated dose toxicity, with a NOEL of 1000
mg/kg/day, the highest dose tested, being identified for the structural analogue.
Positive findings were obtained in in vitro genotoxicity studies but negative findings were
obtained in two in vivo studies. Therefore the notified chemical cannot be classified as a
mutagen.
Overall, based on the submitted information, the notified chemical would be classified as an
eye irritant and a skin sensitiser according to the Approved Criteria for Classifying
Hazardous Substances. Consequently labelling with risk phrases R36 and R43 is appropriate.
Occupational Health and Safety
Transport and Storage
The notified chemical is not manufactured in Australia, but will be imported as a component
in Araldite PT 910 at < 50%. Araldite PT 910 exists as solid, waxy granules, which are not
inhalable. The notified chemical is of low volatility and is therefore unlikely to be available
for inhalation from the imported product. Waterside workers and transport and storage
personnel will only handle Araldite PT 910 as it is imported; in 25 kg polythene bags,
contained in outer packaging. The 25 kg polythene bags will not be opened until arrival at
reformulators. Therefore waterside, transport and storage workers will not be directly
exposed to the notified chemical except in the event of spills.
Reformulation Plant Operators
At reformulation sites, Araldite PT 910 granules are manually weighed and poured from bags
or shovelled using metal scoops, into mixing hoppers. Other raw materials are added and the
mixture is transferred to an extruder either under gravity in a closed system, or poured
manually in an open system. The mix is heated until it melts (>100oC), remixed and then
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
9
extruded onto a roller, where it is spread into a thin sheet. The melted mix solidifies on
cooling and the solid sheets are chipped, milled, sieved and packaged.
The potential for inhalation exposure to the notified chemical in the form of dust exists
during weighing, addition to and extraction from mixing hoppers, during milling and
packaging activities and on disposal of empty containers. According to the notifier local
exhaust ventilation will be in use in all areas where dust containing the notified chemical may
be generated. Dermal exposure may also occur during these activities and also to the melt as
it leaves the extruder. According to the notifier reformulation workers must wear personal
protective equipment consisting of long sleeved overalls, disposable dust masks or a powered
air supplied respirator, chemical goggles, rubber gloves and safety boots, which will
contribute to reducing exposure. Also, the notified chemical is only present at a maximum of
50% in the Araldite PT 910 granules and 1.8% in the extrudate and solidified final product.
However the notified chemical is a skin sensitiser and therefore exposure to small
concentrations may lead to adverse health effects. Also, there is potential for respiratory
sensitisation from breathing of dust containing the notified chemical. Therefore if local
ventilation fails or appropriate PPE is not correctly used as advised there is potential for
adverse health effects to occur.
Quality Control Workers
Quality control personnel will be exposed to the solid extrudate in the form of flakes and
powders during collection of samples, to finely milled powder during milling of the flakes,
and when spraying the fine powders onto test panels. All milling, spraying and cleaning of
laboratory equipment is to be performed in a spray booth with exhaust ventilation. Quality
control personnel will wear personal protective equipment consisting of laboratory coats and
use either powered air respirators or disposable dust masks. Also the notified chemical will
be present at a maximum concentration of approximately 1.8%. Overall, if all control systems
are correctly employed, the risk of adverse health effects should be low in this group of
workers.
Research and Development
Research and development personnel will potentially be exposed to the notified chemical via
inhalation and dermally while working with the granules of Araldite PT 910, the dry-blended
reformulated mixture, the melt mix (dermal exposure only) and final paint products. They
will therefore be exposed to mixtures containing a maximum of 50% notified chemical.
However all research and development is to be performed within a controlled laboratory
fitted with local dust extraction system. Research and development personnel will wear
personal protective equipment consisting of laboratory coats, rubber gloves, safety glasses,
and disposable dust masks. As above, if all controls systems are correctly employed, the risk
of adverse health effects should be low in this group of workers.
Maintenance Workers
Maintenance workers may be exposed via inhalation and dermally to dusts containing the
notified chemical left on the machinery they are required to service. They will therefore be
exposed to mixtures containing a maximum of 50% notified chemical. Local exhaust
ventilation will not be available, although according to the notifier maintenance workers must
wear personal protective equipment consisting of PVC or nitrile rubber gloves and disposable
dust masks. Due to the nature of the work, the lack of exhaust ventilation and assuming that
all other control systems, such as PPE are correctly employed, the risk of adverse health
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
10
effects in this group of workers is at least equal to that of the reformulators noting that
maintenance of equipment should not occur frequently.
Production Administration Workers
Production administration workers are expected to have intermittent contact with the notified
chemical, although when they are to spend lengthy periods of time in the production area they
must wear personal protective equipment consisting of dust coats, and disposable dust masks.
Overall, it is considered that administration workers are unlikely to come into direct contact
with the notified chemical and hence the risk of adverse health effects should be low in this
group of workers.
Application Plant Operators
Applicators will potentially be exposed to the notified chemical in the final product at a
maximum concentration of 1.8% when manually loading the hoppers which automatically
feed the spray gun and when collecting oversprayed coating. However, exhaust ventilation is
used in the loading area and oversprayed powder may be collected using vacuum cleaners.
Exposure may also potentially occur during spraying activities. However, according to the
notifier, all spraying is to be performed in a spray booth fitted with local exhaust ventilation.
Application plant operators must wear personal protective equipment consisting of disposable
overalls and rubber gloves, chemical goggles or face shield and dust masks when exposure is
considered to be minimal, otherwise full-face respirators. If all controls systems are correctly
employed, the risk of adverse health effects should be low in this group of workers.
Overall, the greatest risks of workers experiencing adverse health effects, such as skin
sensitisation and eye, respiratory and skin irritation, due to exposure of the notified chemical,
are considered to be with the maintenance workers and the reformulators. The risks for these
workers are considered to be low.
Public Health
The notified chemical will be used as an ingredient in powder coatings for use on items such
as outdoor furniture, car parts and door and window frames. Products containing the notified
chemical are not available for sale to the public. Members of the public may make dermal
contact with items coated with products containing the notified chemical. However, the risk
to public health from the notified chemical will be negligible because the notified chemical is
present a low concentrations and is likely to be bound within a cured resin coating, from
which it is unlikely to be bioavailable.
Environmental Effects
It is not expected that the new chemical will constitute a hazard to the environment when
used as a curing agent for powder polymer coatings in the manner indicated by the notifier.
A maximum of 2.5 tonnes of the chemical are expected to be placed into landfill each year
with waste resulting from formulation and manufacture of powder coatings. A further
maximum of 3.75 tonnes per annum may be lost from overspray during application of the
powder coatings to metal articles in spray booths, and while some of this would be collected
and re-used, most would be either placed into landfill with other waste, or could possibly be
incinerated. Although not readily biodegradable, the compound is expected to slowly
mineralise to water and landfill gases as a result of slow biological and abiotic processes.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
11
Incineration would destroy the compound with liberation of water vapour and oxides of
carbon.
After application to metal articles, the polymer coating is cured through heat treatment in a
furnace, and after this the chemical is tightly bound into the polymer matrix with no potential
for release.
At the end of their useful lives articles coated with the polymer (and cured through the
agency of the notified chemical) would be either placed into landfill or smelted in a blast
furnace for metal recovery. Smelting would destroy the chemical, while in a landfill the
polymer coating would be eventually degraded through slow biological and abiotic processes.
Ecotoxicicity studies indicate that the chemical may exhibit some toxicity against fish and
daphnia, but at worst the chemical is regarded as slightly to moderately toxic to these species.
However, very little of the notified chemical is expected to reach receiving waters and
realistically it presents no hazard to this compartment. The chemical is not expected to
bioaccumulate.
RECOMMENDATIONS
Regulatory controls
? The NOHSC Chemicals Standards Sub-committee should consider the following
health hazard classification for the notified chemical:
- R36: Irritating to eyes
- R43: May cause sensitisation by skin contact
and use of the safety phrase:
- S22: Do not breathe dust
? Use the following risk phrases for products/mixtures containing the notified chemical:
- > 20%: R36
- > 1%: R43
Control Measures
Occupational Health and Safety
? Employers should implement the following engineering controls to minimise
occupational exposure to the notified chemical as introduced and in final powder
coating products:
- spray painting of powder coatings should be performed in a booth;
- spray painting booths and equipment should be in accordance with Australian
Standard AS3754 -1990 - Safe Application of Powder Coatings by Electrostatic
Spraying;
- local exhaust ventilation should be used when spraying, during filling of hoppers,
when reclaiming powder and during clean-up;
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
12
- automatic spray guns, feed lines and feed equipment should be used;
- spray gun air pressure should be minimised to prevent overspray as this could
result in unnecessary powder build-up within the spray booth;
- the power supply and powder coating feedlines should be interlocked with the air
extraction system so that if a fault develops in the ventilation system, the powder
coating and power supplies are cut off;
- the spread of dust within the powder coating building should be minimized;
- circumstances leading to draughts and air turbulence should be evaluated and
controls implemented;
- operations of opening powder coating packages, loading of hoppers and
reclaiming powder should be contained to prevent or minimise the generation of
dusts;
- the layout of the workstation and the size of the hopper opening should be such
that generation of dust is minimised in filling the hopper, other methods in the use
of hoppers should be considered, namely: large hoppers should be used to avoid
frequent refilling of smaller units, and preference should be given to the use of
powder coatings supplied in drums which allow mechanical transfer of the powder
to hoppers.
? Employers should implement the following safe work practices to minimise
occupational exposure during handling of the notified chemical as introduced and in
final powder coating products:
- work practices designed to avoid the generation of dust;
- restricting access to spray painting areas;
- designing a safe workplace so that the spray painter is never between the object to
be sprayed and the airflow of contaminated air;
- situating the articles to be sprayed sufficiently within the booth to avoid ricochet;
- implementing good personal hygiene practices, for example, powder coating dust
should not be allowed to collect on the face, exposed body areas should be
thoroughly washed and overalls should be regularly cleaned;
- storing powder coating and waste powder in a designated area and access
restricted;
- cleaning booths and surrounding areas on a regular basis;
- promptly cleaning-up spills of powder coatings;
- not using compressed-air or dry sweeping during clean-up operations;
- using a spark-proof squeegee when a wet clean-up is required;
- emptying vacuum cleaners in the booth and under exhaust ventilation;
- taking care to avoid the generation of dust during disposal of waste powder;
- waste powder being baked in the original box for disposal to landfill as a solid;
- vacuuming primary decontamination of work clothing;
- checking regularly the cleaning and maintenance of plant equipment, including
ventilation and spray equipment and filters;
- to minimise electrical hazards associated with electrostatic spraying all equipment,
including spray guns and booth, should be earthed; all hooks used to suspend
objects to be sprayed should be cleaned prior to re-use in order to maintain
effective metal contact.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002

? Employers should ensure that the following personal protective equipment is used by
workers to minimise occupational exposure to the notified chemical as introduced and
in final powder coating products:
- overalls, gloves (PVC or nitrile rubber), head and eye protection and respiratory
protection; for spraying the respiratory protective equipment should provide head
covering to avoid dust build-up around the edges of the face masks; during
manual spraying, the gun-hand must not be insulated from the gun, either the gun
hand should be cowled by a cover sleeve or the palm of an insulating glove may
be cut out; operators standing outside a booth and spraying inside a booth through
an aperture should wear this type of protective equipment; and anti-static and
conductive footwear should be provided.
Guidance in selection of personal protective equipment can be obtained from
Australian, Australian/New Zealand or other approved standards.
? Atmospheric monitoring of dust levels should be conducted to measure workplace
concentrations during formulation and use of the notified chemical.
? A copy of MSDS should be easily accessible to employees.
? If products and mixtures containing the notified chemical are classified as hazardous
to health in accordance with the NOHSC Approved Criteria for Classifying
Hazardous Substances, workplace practices and control procedures consistent with
provisions of State and Territory hazardous substances legislation must be in
operation.
Secondary Notification
Under the Act, secondary notification of the notified chemical may be required if any of the
circumstances stipulated under subsection 64(2) of the Act arise. No other specific
conditions are prescribed.

3 PUBLICATION SUMMARY REPORT
Merquat 2001
Summary Report
Reference No: NA/896
Nalco Australia Pty Ltd of 2 Anderson St Botany NSW 2019 (ABN 41 000 424 788) has
submitted a limited notification statement in support of their application for an assessment
certificate for Merquat 2001. The notified polymer is intended to be used in the formulation
of cosmetic and personal care products, such as soaps and shampoos. Less than 16 tonnes of
the notified chemical will be imported per annum for each of the first five years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
The notified polymer has low acute oral toxicity in rats but is a slight irritant to rabbit skin
and eyes. In a human repeat insult test study, the notified polymer at 20 % in aqueous
solution produced results indicative of sensitisation and/or cumulative irritation during the
induction phase in a small number of subjects, although results indicative of sensitisation
were not seen in a challenge phase using a 5 % aqueous solution of the notified polymer. The
notified polymer was found to be non-mutagenic under the conditions of the test in a bacterial
point mutation assay.
Based on the results of the toxicity studies submitted by the notifier, the notified polymer
would not be classified as a hazardous substance in accordance with the NOHSC Approved
Criteria for Classifying Hazardous Substances. However the results of the human repeat
insult patch test indicate that prolonged or repeated dermal contact with concentrated
solutions of the notified polymer should be avoided.
Occupational Health and Safety
The results of the hazard assessment indicate that skin sensitisation in sensitive individuals
and skin and eye irritation on dermal contact with concentrated solutions of the notified
polymer are the main occupational risks in handling the notified polymer. Little risk is
expected in handling reformulated consumer products containing the notified polymer at low
concentrations.
Workers who may handle the concentrated solutions, apart from in sealed containers only,
include laboratory staff, repackaging operators, and customer service and reformulation
workers. Contact with residues of the notified polymer on equipment may occur when
transfer hoses are connected or disconnected at the drums. All workers handling the notified
polymer in concentrated solutions will wear chemical resistant gloves and safety glasses or
goggles.
Public Health
The use of these products is likely to be widespread among consumers. However the low
toxicity of the Merquat 2001 and the low concentration of it in the proposed consumer
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
15
formulations suggests that it will not pose a significant hazard to public health when used in
the proposed manner.
Environmental Effects
A maximum of 1.6 tonnes of the notified polymer is expected to be placed into landfill each
year with manufacturing waste and domestic garbage containing incompletely consumed
packages of the consumer products. Although it is not readily biodegradable, the polymer is
expected to be slowly mineralised to water and landfill gases as a result of slow biological
and abiotic processes. Some of the polymer may also be incinerated, in which case it would
be destroyed liberating water vapour and oxides of carbon and nitrogen.
Almost all the notified polymer will be released to the sewer as a consequence of its use in
consumer products such as soaps and shampoos. At maximum import levels the Predicted
Environmental Concentration (PEC) of the polymer in sewage is estimated as 15.4 礸/L. The
polymer is expected to remain substantially associated with sewage sludge and very little is
expected to be released with sewer plant effluent to receiving waters. However, assuming no
degradation or assimilation of the polymer into sludge and that a dilution factor of 1:10 is
appropriate, then the PEC in receiving waters would be reduced to 1.54 礸/L.
The EbC50 for green algae (the most sensitive species for which toxicity data is available) is
0.73 mg/L, and taking this as the Predicted No Observed Effect Concentration (PNEC), the
safety margin (Q, which is the ratio PNEC/PEC) is estimated as around 500. Reducing this by
a factor of 1000 to account for the fact that only two ecotoxicity end points are available (for
daphnia and green algae), the Q value becomes 0.5 indicating a possible environmental
hazard. However, receiving waters usually contain suspended colloidal matter of both
mineral and organic origin (eg. humic material), and the interaction of cationic polymers with
this material has been demonstrated to dramatically reduce the toxicity of the polymers. In
addition, most of the notified polymer will become associated with sewage sludge during
passage through the sewer mains and the sewage treatment plants and will not be released to
receiving waters.
It is not expected that the notified polymer will constitute a hazard to the environment when
used in cosmetics in the manner indicated by the notifier. However, if released in quantity to
natural waters (for example as a result of transport accident) the available toxicity data
indicates that such a spill may cause severe ecological damage.
The MSDS supplied by the notifier indicates that the notified polymer is characterised as a
moderate hazard to the environment, and also indicates that the polymer should not be
allowed to enter waterways due to its toxicity to aquatic species.
RECOMMENDATIONS
Regulatory controls
? The NOHSC Chemicals Standards Sub-committee should consider the following
health hazard classification for the notified polymer:
- S24: Avoid contact with skin
- S37: Wear suitable gloves
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
16
Control Measures
Occupational Health and Safety
? Employers should ensure that the following personal protective equipment is used by
workers to minimise occupational exposure to the notified polymer as introduced:
- impermeable gloves, safety goggles and industrial clothing
Guidance in selection of personal protective equipment can be obtained from
Australian, Australian/New Zealand or other approved standards.
? A copy of the MSDS should be easily accessible to employees.
? If products and mixtures containing the notified polymer are classified as hazardous to
health in accordance with the NOHSC Approved Criteria for Classifying Hazardous
Substances, workplace practices and control procedures consistent with provisions of
State and Territory hazardous substances legislation must be in operation.
Secondary Notification
The Director of Chemicals Notification and Assessment must be notified in writing within 28
days by the notifier, other importer or manufacturer:
(1) Under Subsection 64(1) of the Act; if
- the import volume increases above 30 tonnes notified polymer per annum, in
which case a test report on the toxicity of the notified polymer against fish should
be provided;
or
(2) Under Subsection 64(2) of the Act:
- if any of the circumstances listed in the subsection arise.
The Director will then decide whether secondary notification is required.

4 PUBLICATION SUMMARY REPORT
Polymer in Superfloc AF 124 and Superfloc 1264 Flocculants
Summary Report
Reference No: NA/938
Cytec Australia Holdings Pty Ltd of Suite 1, 7-11 Railway Street, Baulkham Hills, NSW
2153 (ABN 45 081 148 629) has submitted a limited notification statement in support of their
application for an assessment certificate for Polymer in Superfloc AF 124 and Superfloc 1264
Flocculants. The notified polymer is an anionic flocculant and is intended to be used for
secondary clarification of industrial wastewater. It will be imported in two finished products -
Superfloc AF 124 and Superfloc 1264 (24-27% and 22-23% notified polymer respectively).
The notified polymer will be imported in 1000 L Intermediate Bulk Containers at a rate of
20-30 tonnes per year for each of the first 5 years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
A combined skin and eye acute irritation study in rabbits of Superfloc AF 124 containing 24-
27% notified polymer resulted in both dermal and ocular irritation, with the product classified
as hazardous with the risk phrases R36/38 ?Irritating to Eyes and Skin according to the
NOHSC Approved Criteria for Classifying Hazardous Substances. The notified polymer is
classified similarly.
The toxicological properties of the products containing notified polymer may be influenced
by the presence of hazardous ingredients such as ammonia and petroleum distillate, which are
inhalation hazards, with the former also a skin, eye and respiratory irritant. Given the high
molecular weight of the notified polymer, absorption across biological membranes is highly
unlikely and consequently, systemic toxicity is likely to be low.
The MSDS for the imported product containing the notified polymer indicates that the
product presents a significant slip hazard.
Occupational Health and Safety
During the dilution and subsequent addition of the imported flocculants containing the
notified polymer to industrial wastewaters, skin contamination may occur, resulting in a risk
of skin and eye irritation. The risk is low during addition of the diluted solution to the
wastewater streams due to the use of metering equipment and the low concentration of
Superfloc. There is also a risk of slipping during handling of the imported flocculants due to
their physical nature.
Therefore, it is important that that the dilution procedure be automated as much as possible
and that safe work practices be introduced to prevent spillage. To further reduce the risks,
appropriate personal protective equipment such as impervious clothing and footwear,
impervious gloves and safety goggles/face shield should be worn by workers when handling
the flocculants containing the notified polymer.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
18
Public Health
Exposure of the public as a result of the use, transport and disposal of products containing the
notified polymer is likely to be negligible. Therefore, the notified polymer is unlikely to pose
a significant risk to public health when used in the proposed manner.
Environmental Effects
The intended use pattern of the notified polymer is expected to result in the majority of the
polymer being eventually released to the environment. The ecotoxicity data provided indicate
the notified polymer is slightly toxic to fish, highly toxic to daphnia and moderately to highly
toxic to marine algae.
Assuming a large urban paper mill or industrial effluent plant treats 5 ML of wastewater each
day and flows into a sewerage treatment system with a capacity of 250 ML, then the
concentration of the notified polymer would be diluted by a factor of 50. Assuming an
industrial effluent plant located in a rural area treats 2 ML of waste each day and flows into a
sewerage treatment system with a capacity of 5 ML, then the concentration of the notified
polymer would be diluted by a factor of 2.5. Assuming these dilution factors, that 80% of the
notified polymer is removed from the wastewater stream through association with effluent
and a dosing rate of the notified polymer of 1 mg/L, then the metropolitan and rural PEC
values are 0.004 and 0.08 mg/L, respectively. When released to receiving waters the
concentration is reduced by a further factor of at least 10, so the Predicted Environmental
Concentration (PEC) for metropolitan and rural use are 0.0004 and 0.008 mg/L, respectively.
Applying an assessment factor of 100 to the EC50 for Daphnia (the most sensitive test
species) suggests the recommended no effect concentration for the notified polymer would be
0.0015 mg/L. The PEC value for use in a metropolitan area is just below the recommended
no effect concentration for the notified polymer (PEC/PNEC = 0.27) while the ratio for use in
a rural area is 5.3. Given this latter ratio is greater than one, it suggests a potential hazard.
When used in a mining situation, the notified polymer is expected to be released to, and
confined within, specialised tailings dams. Biodegradation of the notified polymer is
considered unlikely. However, under the low pH conditions of the tailings dam, the notified
polymer is expected to slowly degrade. When used in the treatment of wastewater from mine
sites, the notified polymer is unlikely to pose a significant risk to the environment.
The notified polymer is not expected to cross biological membranes due to its high molecular
weight and is therefore not expected to bioaccumulate.
Wastes containing the notified polymer including residues from imported drums and sludge
will be disposed of in landfill and are expected to be immobile. Even though the notified
chemical is soluble in water, it is expected to adsorb to soil and sediment due to its high
molecular weight and polyanionic nature. However, some leaching of the notified polymer
can not be discounted.
In conclusion, the environmental exposure and overall environmental hazard from the use of
the notified polymer in pulp and paper manufacture in metropolitan areas seems acceptable
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
19
but in rural areas may be significant. We understand that only metropolitan use is expected at
this time.

Summary Report
Reference No: NA/956
Betzdearborn Australia Pty Ltd of 69-77 Williamson Road, Ingleburn NSW 2565 (ABN 84
001 221 941) has submitted a standard notification statement in support of their application
for an assessment certificate for Prosoft TQ 1003. The notified chemical is intended to be
used as a pulp additive for paper making for toilet and facial tissue. Seventy-two tonnes of
the notified chemical will be imported per annum for each of the first five years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
Based on analogue data, the notified chemical should possess moderate acute oral and dermal
toxicity. Irritation studies in rabbits show that the notified chemical is corrosive to skin and
eyes. Although inhalation toxicity data were not provided for the notified chemical, a similar
corrosive effect would be expected in lungs.
Cases of skin and respiratory sensitisation in humans are reported for quaternary ammonium
compounds analogous to the notified chemical.
No repeat dose toxicity data were provided for the notified chemical. A 91-day oral study of
an analogue established a NOEL of 120mg/kg/day, based on decreased body weight gain. In
a corresponding dermal study in rabbits by the same authors, the NOEL was 200mg/kg/day,
also based on decreased body weight gain. No developmental toxicity data were provided for
the notified chemical. In an analogue study of alkyl imidazoline, no developmental effects
attributable to treatment were observed. On this basis, a developmental toxicity NOEL of
100mg/kg/day and LOEL of > 100mg/kg/day were assigned.
In a bacterial reverse mutation assay, the notified chemical was non-mutagenic. In contrast,
mutagenicity was observed in a mouse lymphoma mutation assay. In a human lymphocyte
chromosome aberration assay the notified chemical was shown to be non-clastogenic. Data
are insufficient for the notified chemical to attract a genotoxic classification.
On the basis of the NOHSC Approved Criteria for Classifying Hazardous Substances, the
notified chemical should be classified Harmful (Xn) and Corrosive (C) with the risk phrases
R20/21/22 ?Harmful by Inhalation, in Contact with Skin and if Swallowed, R34 ?Causes
Burns and R42/43 ?May Cause Sensitisation by Inhalation and Skin Contact.
Occupational Health and Safety
The main activities during which exposure to the notified chemical may occur are decanting
from import containers and routine maintenance of plant during the paper manufacturing
process. Given the enclosed nature of the process, exposure downstream of the initial mixing
process is unlikely. The main routes of exposure are likely to be dermal and ocular from slops
and spills.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
22
The toxicity profile of the notified chemical indicates that if dermal and/or ocular exposure
occurs, especially at the decanting stage where concentrated chemical is handled, severe and
possibly permanent damage is likely to skin and eyes. Although the low vapour pressure
indicates that vapour formation is unlikely, if inhalation exposure does occur, for example
from aerosols produced during manufacturing processes, the severity of effects to skin and
eyes suggests that severe permanent respiratory damage would also result. Moreover, on the
basis of analogue data the notified chemical is a skin and respiratory sensitiser and so
exposure via these routes may be associated with occupational sensitisation.
Although the potential for worker exposure to the notified chemical during paper tissue
manufacture is restricted, the notified chemical is of concern to occupational health and
safety, given the severity of its health effects.
Given the identified exposure routes and these potentially serious health impacts, personal
protective equipment must be used. It is important that during handling of the notified
chemical especially in imported form that skin and eye exposure be prevented by the use of
impervious clothing and footwear, gloves and chemical safety goggles. In addition, given the
unpredictable nature of allergic sensitisation, it is prudent that personnel such as maintenance
workers also be protected from exposure to even small amounts of chemical residue such as
on plant. As a minimum, these workers should also use impervious clothing/footwear and
gloves.
Public Health
Public exposure to the notified chemical arising from use, waste disposal or during transport
is expected to be minimal. The public will be exposed by dermal contact with tissue paper
containing the notified chemical. However, the chemical is likely to be strongly bound to the
fibres of the tissue paper and transfer to skin of the user is expected to be negligible. It is
considered that the notified chemical will not be a significant risk to public health.
Environmental Effects
Approximately 50 tonnes of the chemical will be released to the sewer in association with
used toilet paper. Assuming that the tissue is released into sewers throughout Australia the
global Predicted Environmental Concentration (PEC) of the chemical in sewage is estimated
as 0.05 mg/L. However, the chemical would initially be associated with the solid cellulose
material in paper and not in aqueous solution. As the cellulose fibres break down through
biological action, the chemical may be released but would then associate with negatively
charged humic material and assimilate into sewage sludges. Periodically sludges are removed
from the sewage systems by the water authorities and are usually placed into landfill.
A further 25 tonnes of notified chemical will be placed into landfill with used facial tissue.
Based on an annual quantity of municipal solid waste of 13 million tonnes, the average
concentration of the notified chemical entering landfill from the disposal of facial tissues is
estimated as approximately 2 ppm.
No biodegradation data were provided in the notification, but since the chemical does not
contain any functional groups which are known to be refractory to degradation, it is expected
to be ultimately biodegradable and under aerobic conditions it would be mineralised to water
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
23
and oxides of carbon and nitrogen while in anaerobic environments it would decompose to
water, methane and ammonia.
The release of the notified chemical with the greatest potential for environmental impact is
the discharge of waste water from the pulp and paper mill.
Annually, assuming 90% fixation of the new chemical to fibre, a maximum of approximately
8.4 tonnes will be lost from the paper making process and sent to a water treatment plant
prior to discharge to Lake Bonney. Although the waste treatment plant incorporates a stage of
extended aeration in treatment ponds, the expected low rate of biodegradation indicates that it
is unlikely that much of the chemical would degrade in this plant. However, it is probable that
the chemical would become associated with humic material in solid sludge at the bottom of
the aeration lagoons. The company indicated that waste sludge from this plant is composted
with bark and other materials and this would eventually be applied to land ?probably forests.
The volume of waste water discharged from the paper plant is approximately 40 megalitres
each day, and the maximum concentration of the chemical in the paper plant effluent is
expected to be approximately 0.57 mg/L.
The waste treatment plant consists of a primary clarifier and a series of three aerobic
degradation ponds, and the residence time in the plant is approximately 10 days. After
treatment the effluent then passes into an 11 km drain before discharging into Lake Bonney.
Although biodegradation during the aeration stages is unlikely, it is probable that much of the
chemical would adsorb to humic material in the lagoons and would eventually be assimilated
into bottom sediments. If it is assumed that (as with the paper fibres) around 90% of this
discharged Prosoft TQ 1003 is removed into sediments, the worst case PEC of the chemical
in the effluent discharged to Lake Bonney is estimated as 0.06 mg/L.
Lake Bonney is dune bound and the water level is managed in such a way as to minimise the
need for marine discharge ?release to the marine environment has occurred only twice in the
last decade, and so it appears that the total volume of water flowing into the lake is roughly in
balance with the evaporation rate. Mixing in the lake is not efficient as evidenced by the
measurement of faecal coliform levels around the drain (faecal coliforms are also discharged
in paper mill effluent). The concentration of bacteria decreases rapidly with distance from the
drain. Consequently, for the purpose of making some estimate of the residual chemical
concentration in the lake water, a dilution factor of 1:5 will be assumed, which gives the PEC
in the effluent stream and in Lake Bonney near to the drain discharge of approximately 0.01
mg/L.
The new chemical is toxic to highly toxic to fish (96 h LC50 = 2.2 mg/L for rainbow trout
and 0.93 mg/L for fathead minnow), highly toxic to daphnia (48 h LC50 = 0.22 mg/L) and is
very likely highly toxic to green algae. The PECs above indicate that even for the worst case
PEC of 0.01 mg/L, the safety factor for environmental effects to daphnia is around 20. This
safety factor would be further increased due to association of the chemical with colloidal
organic matter (humic material) in the lake water.
Once the chemical has entered the Lake Bonney water, although only slow biodegradation is
expected, some degradation through direct and indirect photolysis may be possible. However,
it is expected that association with humic material would effectively remove the chemical
through its incorporation into sediments. The chemical is not expected to bioaccumulate.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
24
Provided the new chemical is used for the manufacture of tissue paper as described, it is not
expected to be a hazard to the environment, although some localised impacts could be
possible.

Summary Report
Reference No: NA/991
Ciba Specialty Chemicals Pty Ltd of 235 Settlement Rd Thomastown VIC 3074 has
submitted a standard notification statement in support of their application for an assessment
certificate for Irgacure 2959. The notified chemical is intended to be used as a photoinitiator
in UV-curable lacquers, inks, and varnishes. 1 500 kg of the notified chemical will be
imported per annum for each of the first five years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
Based on the toxicological data provided, the notified chemical would not be acutely toxic
via the oral or dermal routes. It is not likely to be a skin sensitiser, genotoxic, or clastogenic.
It is not likely to be an eye irritant but could be a slight skin irritant. Based on the results of a
28-day oral study in rats (NOAEL 1000 mg/kg bw/day- the top dose), organ or systemic
effects are not expected. The particle size distribution of the notified chemical indicates it
contains a high respirable fraction (84 % of particles are below 10 祄). The notified
chemical would not be classified as a hazardous substance according to NOHSC Approved
Criteria for Classifying Hazardous Substances in terms of the toxicological data provided.
Occupational Health and Safety
There is little potential for occupational exposure to the notified chemical during transport
and storage.
The greatest exposure to the notified chemical is expected to occur during the formulation of
the overprint lacquer, in particular while weighing and manually adding the 99.5 % notified
chemical powder to the mixing vessel. Due to the high percentage of particles in the
respirable range and the possibility of skin irritation, weighing and manually adding the 99.5
% notified chemical powder to the mixing vessel must take place in a well ventilated area.
Blending process workers should wear overalls, PVC coated cotton gloves, protective
goggles and respirators. In the event of inadequate ventilation, self-contained breathing
apparatus (half face mask with cartridge) should be worn.
The engineering controls and personal protective equipment indicated by the notifier should
control the exposure of washing operators, laboratory QC and R & D workers as well as
printer workers using the overprint lacquer to the notified chemical.
Stringent engineering controls, such as a correctly constructed and maintained spray booth,
and a high level of personal protective equipment, such as impermeable overalls and gloves
and a full face mask with a separate air supply should provide adequate protection from the
notified chemical during spray gun application of the powder coating.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
27
The notified chemical becomes biologically unavailable for absorption once it is incorporated
in the surface coating during UV-curing. The health risk for workers handling products
coated with paint containing the notified polymer is considered to be negligible.
Employers should ensure that NOHSC exposure standard for a nuisance dust (10 mg/m3
TWA) is not exceeded in the workplace. Employers should also note that while NOHSC does
not have an exposure standard for the respirable fraction of dust, the American Conference of
Governmental Industrial Hygienists have developed an occupational exposure standard of 3
mg/m3 TWA for the respirable dust fraction.
Given the risk reduction measures indicated and that the notified chemical is unlikely to be
hazardous, Irgacure 2959 is of low concern to human health and safety in the workplace.
Public Health
The public may be exposed to the notified chemical either as a pure powder or as a
component of an ink lacquer following transport accidents involving the breakage of the
containers in which they are carried. Such accidents are unlikely. Where they do occur,
contact with the powder form is likely to be dermal and minimal and transient. Contact with
spilled varnish containing the notified chemical may be hazardous because of the presence of
other chemicals. Members of the public may also be exposed to the notified chemical as an
environmental contaminant. This is also unlikely as any waste is chemically and physically
reduced to inert material and disposed of as land-fill.
Public contact with the notified chemical is expected to be by means of contact with it as a
component of cured varnish on packaging. However it will be present in the varnish at a low
concentration and in a state inaccessible to human contact. The low likelihood of exposure to
the notified chemical and the toxicological profile of the notified chemical suggest that the
notified polymer will not pose a significant hazard to public health when used in the proposed
manner.
Environmental Effects
The majority of the notified chemical will be incorporated in printed packaging material.
However, prior to leaving the printers, the printed material is irradiated with UV light which
promotes homolysis of the bond ether linkage in the notifier chemical which then initiates a
free radical polymerisation process to form a high molecular weight, crosslinked compound.
Therefore, once incorporated into the printed material, the notified chemical is consumed and
poses little risk to the environment.
The ecotoxicity data indicate the notified chemical is moderately toxic to algae, but appears
to be practically non-toxic to fish and daphnia. The notified chemical is not readily
biodegradable, however, in water the notified chemical is expected to degrade
photochemically.
The wastes containing the notified chemical generated during the formulation process will be
disposed of in landfill. The notified chemical has a log KOC of 1.05 and a relatively high
water solubility. Therefore it will be mobile in both the terrestrial and aquatic compartments.
Analysis of the notified chemical's physico-chemical properties using the Mackay Level 1
Fugacity Model indicates that 99.34% of releases will remain in the aquatic compartment.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
28
Liquid wastes containing the notified chemical will be incinerated by licensed waste disposal
contractors and are expected to produce water vapour and oxides of carbon.
The notified chemical's high water solubility and log P value indicate it has a low
bioaccumulation potential.

Polymer in RW 3210
Summary Report
Reference No: NA/992
BASF Akzo Nobel Automotive OEM Coatings Pty Ltd (ACN 092 127 501) and Akzo Nobel
Pty Ltd (ACN 000 119 424) of 51 McIntyre Road Sunshine VIC 3020 have submitted a
limited notification statement in support of their application for an assessment certificate for
Polymer in RW 3210. The notified polymer is intended to be used as a component of an
automotive primer paint. Less than 1500 tonnes of the notified polymer will be manufactured
per annum for each of the first five years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
No toxicological data have been provided for the notified polymer. The notified polymer has
a high NAMW, and absorption across biological membranes and resultant systemic toxicity
would be restricted. It contains a low proportion of reactive functional group and a low
content of residual monomers. Therefore, the notified polymer is unlikely to be a hazardous
substance according to the NOHSC Approved Criteria for Classifying Hazardous Substances.
The Material Safety Data Sheet (MSDS) for RW 3210 emulsion indicates that the emulsion
may be slightly irritating to skin, eyes and respiratory tract. The reported heath effects are
likely to relate to other components of the emulsion, such as solvents, rather than the notified
polymer.
Occupational Health and Safety
The notified polymer is manufactured in Australia for formulation into an automotive primer.
The intermediate and final aqueous emulsions are formulated in closed vessels. The
intermediate polymer emulsion is transferred in enclosed lines to a closed blend tank where
additional components are added to form the final paint additive emulsion. After sampling for
quality analysis, the emulsion is then stored prior to transport in bulk containers to
automobile manufacturing facilities. Incidental exposure to the notified polymer may occur
during transfer of RW 3210 to storage tanks or mixing vessels.
The notified polymer is never isolated and therefore occupational exposure to the polymer for
process, maintenance and laboratory workers would only occur from contact with the
aqueous polymer emulsions (containing <30% notified polymer). Contact may result in slight
skin and eye irritation. Given the engineering controls, personal protective equipment
available to these workers, and the low probability of exposure and likely low systemic
toxicity of the notified polymer, the overall health risk for workers involved in polymer
manufacture and formulation is assessed as low.
The notified polymer is transported in bulk containers for end-use in the form of an emulsion
to be added to automotive primer paint. The potential for exposure to the notified polymer
during storage and transport would be considered low and would only be envisaged following
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
31
accidental puncture of the bulk containers. Therefore, the health risk for transport workers
would be assessed as low.
The paint additive containing the notified polymer will be mixed in a tank which will be used
to coat automotive bodies by dipping. At this point, exposure to diluted notified polymer
(<10%) would only occur as a result of contact with the final paint. As this process is
automated, the possibility of exposure is low and would be envisaged only following
accidental spillage during routine operations, maintenance or laboratory analysis.
Following curing of the paint, the polymer will be cross-linked with other paint components
to form a high molecular weight stable film. In this form, the polymer is essentially
unavailable for absorption and thus the health risk to workers from the notified polymer after
paint curing would be negligible.
Given the controls in place and the likely low toxicity of the notified polymer, the health risk
to workers involved in end use of the notified polymer is assessed as low.
Public Health
The polymer emulsion and the final paint additive will not be sold to the public and the
application will be restricted to car manufacturers. The public may come in contact with the
notified polymer only after it has been applied to and becomes an integral part of a hard film
covered by more layers of paint on motor vehicles. Therefore, the risk to the public induced
by the notified polymer is considered to be low.
Environmental Effects
The majority of the notified polymer will be combined with other coating components to
form a very high molecular weight and stable coating. Therefore, once incorporated into the
coating formulation, the notified polymer is expected to be immobile in the environment. As
the coating degrades over time, any fragments, chips and flakes of the coating will be of little
concern as they are expected to be inert. The metal panels and car bodies coated with the
polymer are likely to be either recycled for steel reclamation or be placed into landfill at the
end of their useful life. During recycling, the polymer would be destroyed in furnaces and
converted to water vapour and oxides of carbon and nitrogen.
The notified polymer in waste from spills and equipment cleaning will be passed through
interceptor pits and will be treated on-site by flocculation. The resulting solid containing the
notified polymer will be dried followed by disposal into landfill while the water will be tested
prior to release into the sewer. Wastewater resulting from the cleaning of bulk transportation
tanks will be collected and used in the formulation of new polymer batches.
As a consequence of its hydrophobic nature, the notified polymer is expected to associate
with the soil matrix and sediments. The notified polymer is not expected to cross biological
membranes due to its high molecular weight and is therefore not expected to bioaccumulate.

RECOMMENDATIONS
Control Measures
Occupational Health and Safety
No specific precautions are required for the notified polymer itself, however, due to the
presence of hazardous components in the aqueous emulsions and final primer paint:
? Employers should implement the following engineering controls to minimise
occupational exposure:
- Enclosed fixed transfer lines for transfer operations
- Closed reactor, emulsification tank and blend tank
- Exhaust ventilation during manufacture, QC analysis, storage and paint
application;
? Employers should implement the following safe work practices to minimise
occupational exposure during handling of the polymer emulsions and the final primer
paint:
- Prevent splashes and spills;
? Employers should ensure that the following personal protective equipment is used by
workers to minimise occupational exposure to the polymer emulsion and the final
primer paint:
- chemical goggles or safety glasses with side shields
- chemical resistant industrial clothing
- PVC or rubber gloves
- protective footwear;
Guidance in selection of personal protective equipment can be obtained from
Australian, Australian/New Zealand or other approved standards.
? A copy of the MSDS should be easily accessible to employees.
If products and mixtures containing the notified polymer are classified as hazardous to health
in accordance with the NOHSC Approved Criteria for Classifying Hazardous Substances,
workplace practices and control procedures consistent with provisions of State and Territory
hazardous substances legislation must be in operation.

HP Australia Limited of 31-41 Joseph Street, Blackburn VIC 3130 (ABN 74 004 394 763)
has submitted a standard notification statement in support of their application for an
assessment certificate for NT-18. The notified chemical is intended to be used as an
ingredient of a toner for electrophoto-copying machine or electrophoto-graphic printer and
will be contained in toner at less than 1%.
Annual imports of the notified chemical over the next five years are anticipated to be less than
20 tonnes.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
Based on the toxicological data provided, the notified chemical would not be acutely toxic
via the oral and dermal route. It is not likely to be a skin sensitiser or genotoxic. It is not
likely to be a skin irritant but could be a slight eye irritant. The no-observed-adverse effect
level (NOAEL) established in a 28-day repeat dose oral study in rats was 1000 mg/kg bw/day
(highest dose tested with no treatment-related effects).
The notified chemical is not classified as a hazardous substance according to the National
Occupational Health and Safety Commission (NOHSC) Approved Criteria for Classifying
Hazardous Substances.
Data on the particle size of the notified chemical show that a large proportion of the particles
are within the respirable range (24% by weight<10 祄). Also, the toner is formulated as a
powder with average particle size from 5 祄 to 10 祄 and distribution from 1 祄 to 30 祄.
The toner is considered a nuisance dust and employers are responsible for maintaining
atmospheric levels of toner dust below the NOHSC exposure standard of 10 TWA mg/m3.
Australia does not have a national exposure standard for respirable dust, however, the
American Conference of Governmental Industrial Hygienists TLV is 3 TWA mg/m3.
The material safety data sheet (MSDS) for the toner states that it would not be classified as a
hazardous substance according to the Approved Criteria for Classifying Hazardous
Substances.
Occupational Health and Safety
Exposure to toner containing the notified chemical can occur during machine operation,
during clearing paper feed problems and machine maintenance. Transport and storage of the
toner bottles and cartridges is unlikely to result in worker exposure except in the event of
accidental spillage.
From the repeat dose toxicity studies, the NOAEL of 1000 mg/kg bw/day (highest dose tested
with no treatment related effects) was established for NT-18. Assuming 100% dermal
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
35
absorption, a 70 kg worker would need to be dermally exposed to 70 g NT-18/day or >7 kg
toner/day to reach the NOAEL. This is unlikely given the routine conditions of use. The
calculations described do not include a safety factor.
The main route of exposure is dermal. While ocular exposure to toner dust may occur, the
risk of eye irritation in workers involved in transport, storage, use and disposal of the notified
chemical in this application is low.
Printing staff performing additions of toner and replacement of a used toner container
(cartridge or bottle) are expected to be exposed infrequently to the notified chemical as the
toner container is sealed and loaded directly into a printing machine. Upon application to the
paper, the toner is fused to the surface and release is unlikely to occur. Therefore, the risk of
adverse health effects to printing personnel is low and no personal protective equipment is
required. Nevertheless, due to the small toner particle size, any generation of dust should be
avoided.
Service personnel may be exposed to the notified chemical when cleaning printer/copier
equipment and replacing copier developer. However, as the notified chemical is not likely to
be hazardous and given its low concentration in the toner (<1%), the risk of adverse health
effects is low. Cotton or disposable gloves may be worn to prevent skin irritation due to
frequent exposure to toners, and workers should avoid any generation of dust when handling
the toner.
Spilt residues should be swept up manually or using a dust explosion-proof vacuum cleaner
and placed within a waste container.
Workers handling printed paper are not at risk of adverse health effects because the polymer
is fixed to the paper and not available for exposure or dermal uptake.
Given these considerations, the chemical will not pose a significant health hazard in the
occupational environment.
In the event that the notified chemical will be handled as a raw ingredient at high
concentrations, workers should be protected from skin contamination because it has staining
properties.
Public Health
There is potential for public exposure to the notified chemical from spillage of the toner
during exchange of cartridges in printers and photocopiers. However, given the low toxicity
profile of NT-18 and the very low proportion of NT-18 in the toner, the potential for dermal
and inhalational exposure of the public to the notified chemical during use of the toner
cartridges is considered to be very low.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002

Environmental Effects
Although the notified chemical is moderately toxic to green algae it does not exhibit acute
toxicity to either fish or daphnia up to the limit of its water solubility, but is slightly toxic to
daphnia under conditions of chronic exposure. However, the compound is not expected to be
released to the water compartment except at very low concentrations, and this in a very
diffuse manner. Consequently, use of the compound as indicated as a component of toners
for printers and photocopying is not likely to constitute a hazard to the aquatic compartment.
In the event of accidental spillage or release of the toner, the clean up operation would
probably entail disposal to landfill. The long term fate of the majority of the notified
chemical is expected to be either through paper recycling, landfill disposal or incineration of
waste paper. In the first two cases it is anticipated that the chemical would be destroyed
either by a vigorous chemical environment (paper recycling) or through slow biological and
abiotic processes. Even in the absence of substantial degradation, the relatively low usage
rate and diffuse nature of disposal patterns indicates very slow release into the wider
environment, and this at low concentrations. Incineration of the chemical would lead to its
total destruction with production of water and oxides of carbon and nitrogen while the
sodium and iron components would report to ash.
However, the notified chemical is not expected to have affinity for soil and if released to soil
or sediments will be mobile in these media and is expected to be slowly leached into the
water compartment. The chemical is not expected to have potential for bioaccumulation.
The notified chemical is not considered to be a hazard to the environment when used as a
component of printer and photocopying toner as indicated.
RECOMMENDATIONS
To minimise occupational exposure to NT-18 the following guidelines and precautions
should be observed:
? In case manufacturing of the notified chemical or toner is performed in Australia,
protective eyewear, clothing and gloves should be worn when handling the
notified chemical;
? Generation of dust clouds when handling the toner should be avoided;
? Service operators should wear cotton or disposable gloves when handling the
toner (ie when removing spent cartridges or bottles containing the notifed
chemical or when servicing printers or photocopiers);
? Spillage of the notified chemical should be avoided. Spillage should be cleaned
up promptly with absorbents which should be put into containers for disposal;
? A copy of the appropriate MSDS should be easily accessible to employees.
If products containing the notified chemical are hazardous to health in accordance with the
Approved Criteria for Classifying Hazardous Substances, workplace practices and control

Polymer in RW0978
Summary Report
Reference No: NA/995
Akzo Nobel Pty Ltd and BASF Akzo Nobel Automotive OEM Coatings Pty Ltd both of 51
McIntyre rd Sunshine VIC 3020 have submitted a limited notification statement in support of
their application for an assessment certificate for Polymer in RW0978. The notified polymer
is intended to be used as a component of a surface coating. Less than 20 tonnes of the
notified polymer will be imported per annum for each of the first five years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
No toxicological data have been provided for the notified polymer. However, given its high
molecular weight, low proportion of reactive functional groups (amine groups) and low
concentration of residual monomers, the notified polymer is unlikely to be a hazardous
substance in accordance with the NOHSC Approved Criteria for Classifying Hazardous
Substances. The systemic toxicity of the notified polymer is likely to be low, given its high
molecular weight and consequent low bioavailability.
The Material Safety Data Sheet (MSDS) for RW0978 emulsion indicates that the emulsion
may be irritating to skin and eyes and may cause kidney and liver damage if swallowed; these
effects are based on the effects of organic solvents present in RW0978.
Occupational Health and Safety
The notified polymer is manufactured and emulsified in closed vessels. The resulting
polymer emulsion is then transferred in enclosed lines to a closed blend tank where additional
components are added to form the final paint additive emulsion. After sampling for quality
analysis, the aqueous emulsion is then stored prior to transport in bulk containers.
The notified polymer is never isolated and therefore exposure to the polymer for process,
maintenance and laboratory workers would only occur from contact with diluted polymer
emulsion or final paint additive containing <30% notified polymer. Contact may result in
slight skin and eye irritation. However, given the engineering controls and personal protective
equipment worn by these workers, the low probability of exposure and likely low systemic
toxicity of the notified polymer renders the overall health risk for workers involved in
polymer manufacture low.
The notified polymer is transported in bulk containers for end-use in the form of an emulsion
to be added to automotive primer paint. The potential for exposure to the notified polymer
during storage and transport would be considered low and would only be envisaged following
accidental puncture of the bulk containers. Therefore the health risk for transport workers
would be assessed as low.
The paint additive containing the notified polymer will be mixed in an electrocoat tank which
will be used to coat automotive bodies and parts by dipping. At this point, exposure to diluted
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
39
notified polymer (<10%) would only occur as a result of contact with the final paint. As this
process is automated, the possibility of exposure is low and would be envisaged only
following accidental spillage during routine operations, maintenance or laboratory analysis.
Given the likely low toxicity of the notified polymer, the health risk to these workers
involved in end use would be assessed as low.
Following curing of the paint, the polymer will be cross-linked with other paint components
to form a high molecular weight stable film. In this form, the polymer is essentially
unavailable for absorption and thus the health risk to workers from the notified polymer after
paint curing would be negligible.
Public Health
The very low likelihood of contact with the notified polymer and the low toxicity of the
notified polymer suggest that the notified polymer will not pose a significant hazard to public
health when used in the proposed manner.
Environmental Effects
The majority of the notified polymer will be combined with other coating components to
form a very high molecular weight and stable coating. Once incorporated into the coating
formulation, the notified polymer is expected to be immobile in the environment. As the
coating degrades over time, any fragments, chips and flakes of the coating will be of little
concern as they are expected to be inert. The metal panels and car bodies coated with the
polymer are likely to be either recycled for steel reclamation or be placed into landfill at the
end of their useful life. When recycled the polymer would be destroyed in furnaces and
converted to water vapour and oxides of carbon and nitrogen.
The notified polymer in waste from spills and equipment cleaning will be passed through
interceptor pits and will be treated on-site by flocculation. The resulting solid containing the
notified polymer will be dried followed by disposal into landfill while the water will be tested
prior to release into the sewer. Wastewater resulting from the cleaning of bulk transportation
tanks will be collected and used in the formulation of new polymer batches.
As a consequence of its hydrophobic nature, the notified polymer is expected to associate
with the soil matrix and sediments and not be mobile but slowly degrade. The notified
polymer is not expected to cross biological membranes due to its high molecular weight and
is therefore not expected to bioaccumulate.
RECOMMENDATIONS
Control Measures
Occupational Health and Safety
No specific precautions are required to control exposure to the notified polymer. However,
the following precautions should be taken when handling the aqueous emulsions and paints
containing the notified polymer:

? Good ventilation;
? Protective eyewear, impermeable gloves and chemical resistant industrial clothing and
footwear.
Guidance in selection of personal protective equipment can be obtained from Australian,
Australian/New Zealand or other approved standards.
? A copy of the MSDS should be easily accessible to employees.
If products and mixtures containing the notified polymer are classified as hazardous to health
in accordance with the NOHSC Approved Criteria for Classifying Hazardous Substances,
workplace practices and control procedures consistent with provisions of State and Territory
hazardous substances legislation must be in operation.

Summary Report
Reference No: PLC/217
BASF Australia Ltd (ABN 62 008 437 867) of 500 Princes Highway Noble Park VIC 3174
has submitted a synthetic polymer of low concern (PLC) notification statement in support of
their application for an assessment certificate for Polymer in Collacral LR 8990. The notified
polymer is intended to be used as a thickener in water based architectural paint formulations.
10 - 100 tonnes of the notified polymer will be imported per annum for each of the first five
years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
The notified polymer fulfils the criteria for a synthetic polymer of low concern and can be
considered not to be a health hazard.
The technical bulletin for the 40% aqueous solution of the polymer states that prolonged
exposure may cause irritation of the skin and mucous membranes.
Occupational Health and Safety
Transport and storage of the containers of notified polymer should result in minimal worker
exposure and consequent health effects except in the event of accidental container rupture.
During the paint manufacture processes, the main exposure route for the notified polymer
will be dermal. The paints will be viscous, and ready formation of aerosols is not expected.
There is a risk of slight irritation (dermal, ocular) should spillage occur as indicated on the
MSDS for the imported polymer solution.
Occupational exposure during the sale and professional use of architectural paints is likely to
be widespread and often under poorly controlled conditions. Dermal contact during handling
and application of the paints is likely. The occupational health and safety risk associated with
dermal contact with the notified polymer in the form of uncured paints will be low, due to the
low toxicological hazard of the polymer and the low concentration (< 2 %) in the finished
paints.
Conclusion
The notified polymer is of low concern to human health and safety and no specific risk
reduction measures are necessary.
Public Health
While dermal and possibly eye contact with the notified polymer may occur during
application of the paints containing the polymer by the public, the notified polymer is not
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
42
expected to pose a significant hazard to public health when used in the proposed manner
based on its expected low toxicity.
In dried paint films, the notified polymer will be encapsulated in an inert, very high
molecular weight matrix, which will render it biologically unavailable, and consequently
public exposure to the notified polymer from dried paint films is considered to be low.
Environmental Effects
The majority of the notified polymer will be bound with other paint components in a high
molecular weight and stable paint film. Therefore, once incorporated into the paint
formulation, the notified polymer is expected to be immobile and pose little risk to the
environment.
The notified polymer in waste from spills and equipment cleaning will be collected by
licensed waste disposal contractors and will either be disposed of in landfill or incinerated.
Small spills will be washed into the notifier's on-site effluent treatment plant where wastes
are treated with flocculants to remove solids prior to discharge to sewer. Therefore, release of
the notified polymer is expected to be low. Solid wastes from this process will be disposed in
landfill.
Equipment used to apply the paint will be washed in water and the notified polymer may be
disposed into the sewer or poured onto the ground. When dried paint containing the notified
polymer is disposed of in landfill or onto the ground, it is expected to become associated with
the soil matrix. Incineration of wastes containing the notifier polymer will produce water
vapour and oxides of carbon and nitrogen. When released into the sewer, the notified
polymer's high water solubility suggests that it will be predominantly remain in the aquatic
compartment, where it will become diluted and dispersed, eventually associating with
sediments.
In a worst case based on maximum annual releases of 4.5 tonnes per annum, all of which is
released to sewer, assuming that none is removed during sewage treatment processes, and
assuming a national population of 19,000,000 and that each person contributes an average
150 L/day to overall sewage flows, the predicted concentration in sewage effluent on a
nationwide basis is estimated as 4.3 microgram/L. When released to receiving waters the
concentration is generally understood to be reduced by a further factor of at least 10, and so
the Predicted Environmental Concentration (PEC) is around 0.43 microgram/L. Due to the
water solubility of the notified polymer most would be expected to remain in the water
column. Some will be treated with flocculents and removed prior to release to receiving
waters, further reducing this concentration.
The notified polymer is not expected to cross biological membranes due to its high molecular
weight is therefore not expected to bioaccumulate.

Infineum Australia Pty Ltd of 2/6 Riverside Quay Southbank VIC 3006 (ABN 24084581
863) has submitted a synthetic polymer of low concern (PLC) notification statement in
support of their application for an assessment certificate for Infineum C9510. The notified
polymer is intended to be used as a lubricant additive. Fifty tonnes of the notified chemical
will be imported per annum for each of the first five years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
The notified polymer fulfils the criteria for a synthetic polymer of low concern and can be
considered not to be a health hazard. It will be present in oil additive packages at a
concentration of 2% but the formulation is yet to be finalised.
Occupational Health and Safety
During import and transport of the notified polymer, worker exposure is unlikely except in
the event of a spill. Exposure after a spill would be controlled by use of the recommended
practices for spillage clean up outlined in the MSDS supplied by the notifier.
During reformulation into a finished lubricant and repackaging of the lubricant into consumer
sized containers, workers will not experience adverse health effects from their low exposure
to the notified polymer as little of the lubricant additive package will be spilt during transfer,
the notified polymer is at a low concentration and it is not a health hazard. The MSDS
recommends the use of PVC or nitrile gloves with inner gloves if thermal protection is
required. If handling hot material workers are advised to wear a face shield and don chemical
resistant apron, jacket and rubber boots.
Customers of the finished lubricant and their employees will receive negligible exposure to
the notified polymer because of its low concentration in the final lubricant. In addition, gear
oil is filled automatically into new cars. Therefore, the risk of adverse health effects for these
workers arising from exposure to the notified polymer is negligible.
Used gear oil or crankcase oil for disposal is expected to be collected by a licensed contractor
and sent for recycling or incineration. Again the low concentration of the notified polymer in
the final lubricant together with its expected low hazard should prevent any adverse health
effects to workers.
Conclusion
The notified polymer is of low concern to human health and safety and no specific risk
reduction measures are necessary.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
45
Public Health
The imported lubricating oil additive package will not be sold to the public. There is public
accessibility to the notified polymer after its incorporation into engine oil. Public exposure to
the notified polymer occurs when oil changes of the car are required. However, taking into
account its physical and chemical properties, its expected low toxicity, and the low
concentrations in end use lubricating oil, the exposure is unlikely to cause significant public
health concerns.
Environmental Effects
Losses of the notified polymer to the environment during transport, blending and repackaging
are expected to be small, while losses through improper disposal during lubricant oil change
may be higher. Exact figures arising from improper disposal of used lubricants are difficult to
estimate because of the uncertainty surrounding the fate of 40% of used oils generated in
Australia. However, the notifier anticipates that over 90% of the imported volume of
polymer, generated as used oil, would be disposed of properly, either by incineration and
recycling, and less that 10% could be released into the soil environment or into stormwater
drains through improper use or disposal.
The bulk of recycled polymer will be incinerated in fuel oils. Incineration will result in the
production of water vapour and oxides of carbon. Disposal into the soil environment will
result in adsorption of the polymer onto soil particles, while release into waterways would
result in the polymer floating on the surface and eventually becoming associated with sludge
and sediments. The polymer is not readily biodegradable, but in soils, it is expected to slowly
degrade through microbial and abiotic processes.
The environmental hazard from the notified polymer is considered to be small given the
anticipated nationwide use; provided that the material is used as indicated and disposal of
used oil takes place via the proper routes such as recycling and incineration.
RECOMMENDATIONS

has submitted a synthetic polymer of low concern (PLC) notification statement in support of
their application for an assessment certificate for Urethane Polymer. The notified polymer
will be used as a component of a fabric/fibre stain protector. The stain protector will be used
predominantly on carpets and rugs and applied as a foaming spray. The notified polymer will
be imported 50 kg/year for the first five years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
No toxicological information has been provided for the notified polymer. However, due to its
high molecular weight and presence of only low concern reactive functional groups, it is
unlikely to be a hazardous substance in accordance with the NOHSC Approved Criteria for
Classifying Hazardous Substances. The notified polymer meets the criteria for a Polymer of
Low Concern and thus is unlikely to represent a health hazard.
Occupational Health and Safety
Exposure to the notified polymer is not expected during import and handling of pressurised
cans containing 1-5% notified polymer. Cans are not opened prior to end-use and so
occupational exposure of import/storage and relabelling plant workers to the polymer would
only be envisaged in the case of accidental rupture of containers or inadvertent activation of
the release valve. These are unlikely given the low concentration of notified polymer in the
product (1-5%), the strength of the containers and covering of the release valve by a cap that
would require removal only during end use.
If any of the above scenarios occurs, dermal, ocular and inhalation exposure may be
envisaged. Based on the MSDS for the product (an aqueous suspension of notified polymer),
if skin, eye or inhalation exposure occurs, local irritation may result. The MSDS further
warns that intentional overexposure can be harmful or fatal. It is likely that this and cautions
regarding central nervous system depression following overexposure are likely to be due to
the solvent propellant (isobutane) and not the notified polymer.
Given the engineering controls, low possibility of exposure and the low health hazard
associated with the notified polymer, the health risk for workers handling the notified
polymer from import, relabelling through to retail would be assessed as low.
Public Health
The two most likely avenues for exposure are dermal contact and inhalation. After treatment,
the product remains on the treated surface and may be slightly irritant. However, once the
product has dried there is likely to be limited exposure to the public as the product is intended
to remain in contact with the treated material. The product is potentially harmful if
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
48
intentionally inhaled in concentration, however, it is likely that this is due to the solvent
propellant and not the notified polymer. The notifier expects very little mist produced from
proper use. The risk to public health is therefore not likely to be significant.
It is noted that draft labels for the product containing the notified polymer advise that contact
with the wet product should be avoided.
Environmental Effects
The majority of the notified polymer will be applied to carpet and rugs as a foaming aerosol
which when dry remains on the treated article with little overspray expected. Therefore, most
will be released into the environment through disposal of carpet and rugs in landfill. The
notifier also indicates that overtime the notified polymer may, through mechanical action,
slowly wear off the carpet surface and be vacuumed away. However, this is expected to be
minor. The notified polymer in these products will slowly degrade through abiotic and biotic
processes to oxides of nitrogen and carbon. Incineration of the notified polymer will produce
oxides of nitrogen and carbon and water vapour.
Empty import cans and any residual notified polymer they may contain will be disposed of in
landfill. These residues are not expected to escape form the can but if they did the notified
polymer is expected to be immobile due to its low water solubility and will become part of
the soil matrix.
The polymer is not expected to cross biological membranes due to its high molecular weight.
Therefore the notified substance is not expected to bioaccumulate.
RECOMMENDATIONS
Control Measures
Occupational Health and Safety
? No special precautions are required for the notified polymer. However, in the interests
of good occupational hygiene practice, employers should ensure that the following

DuPont (Australia) Ltd of 49-59 Newton Road Wetherill Park NSW 2164 (ACN 000 716
469) has submitted a synthetic polymer of low concern (PLC) notification statement in
support of their application for an assessment certificate for RC 25433. The notified polymer
is intended to be used as a primer for automotives. Less than 100 kg of the notified chemical
will be imported for the first year, increasing to <1tonne per annum for the next four years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
No toxicological information was provided for the notified polymer. However, the notified
polymer has a high molecular weight and is unlikely to penetrate biological membranes. It
contains no reactive functional groups and residual monomers are present below the relevant
concentration cut offs for classification of the notified polymer as a hazardous substance. The
polymer meets the PLC criteria and is unlikely to be a hazardous substance according to the
NOHSC Approved Criteria for Classifying Hazardous Substances.
The notified polymer will be imported as a component of an automotive epoxy primer mixed
in a number of solvents. The MSDS for the epoxy primer containing <10% notified polymer
states that it may cause irritation to the eyes, skin, nose and throat, and gastrointestinal
distress when swallowed. Inhaling the solvent vapours may cause central nervous system
depression, headache, dizziness, nausea, staggering gait, confusion and unconsciousness.
Prolonged overexposure to solvents has been reported to be associated with permanent brain
and central nervous system damage.
The notifier classified the epoxy primer as a non-hazardous substance according to the
NOHSC Approved Criteria for Classifying Hazardous Substances, since the solvents listed
on the NOHSC List of Designated Hazardous Substances are present at concentrations below
the relevant cut off levels for health hazard classification. The appropriate NOHSC exposure
standards for the solvents are also listed in the MSDS.
The epoxy primer is classed as a dangerous good, Class 3, flammable liquid, due to the
presence of solvents.
Occupational Health and Safety
The greatest exposure to the notified polymer is during paint make-up and use of the epoxy
primer. Paint make-up should take place in a well-ventilated area.
The final paint mix including the epoxy primer contains a wide variety of solvent and other
ingredients, which are likely to introduce human health hazards. The spraying procedure also
produces a dense aerosol which could adversely affect human health even in the absence of
additional hazardous components. It is also probable that professionals involved in the spray
painting industry will use a number of different paint formulations.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
51
The epoxy primer and the final paint mix containing the notified polymer are flammable due
to their solvent content. Precautions must be taken to avoid sources of ignition, e.g. use of
earthing leads. Operators should wear antistatic overalls and footwear.
For these reasons, the notified polymer must be assessed for the contribution it makes to the
hazards associated with spray application of the paint. The spray application requires the use
of stringent engineering controls, such as a correctly constructed and maintained spray booth,
and of a high level of personal protective equipment, such as impermeable overalls and
gloves and a full-face shield and respirator. The use of the paint containing the notified
polymer should be in accordance with the NOHSC National Guidance Material for Spray
Painting. The level of protection from exposure afforded by the standard protective measures
will provide adequate protection from the notified polymer, which is likely to be less
intrinsically toxic than most of the solvents and pigments in the epoxy primer. The low
toxicological impact and the control measures in place render the health risk from the notified
polymer for the workers as low.
Similar considerations apply in the cleaning of spray equipment and disposal of the polymer.
The precautions used for the additional materials should be adequate for protection from the
notified polymer. In addition, much of the polymer will be crosslinked and hardened, and
therefore immobile, by the time of disposal.
Once the applied final paint mix has hardened, the polymer will not be separately available
for exposure or absorption.
There is no occupational exposure expected for transport and storage workers except in case
of an accident. The health risk for these workers is expected to be negligible under normal
conditions.
The notified polymer itself is of low hazard to human health and safety. Apart from the
controls already in place to prevent exposure to other paint components and to the notified
polymer in particulate form during spraying, no additional controls are required.
There are NOHSC exposure standards for the solvents identified as ingredients in the
imported epoxy primer containing the notified polymer. The employer is responsible for
ensuring that these exposure standards, and exposure standards pertaining to other final paint
mix additives, are not exceeded in the workplace.
Public Health
The epoxy primer containing the notified polymer will be used by professional commercial
spray-painters consequently, public exposure is likely to be negligible, except in the event of
an accidental spill during transport. Automobiles painted with the epoxy primer system will
be heat cured, such that the polymer will react with other components in the paint formulation
to form an inert, very high molecular weight paint film. This coating will be over-coated with
top coats, which will themselves undergo a similar curing process. Therefore, the risk to the
public from exposure to the notified polymer through all phases of its life cycle is considered
to be low.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
52
Environmental Effects
The majority of the notified polymer will be crosslinked with other paint components to form
a very high molecular weight and stable paint film. Therefore, once incorporated into the
paint formulation, the notified polymer is expected to be immobile and pose little risk to the
environment.
The notified polymer in waste from spills and equipment cleaning will be collected by
licensed waste disposal contractors and treated by a distillation process whereby the solvent
is reclaimed and the remaining solid containing the notified polymer will be disposed of in
landfill or combined with asphalt and used as a road base tackifier. The notified polymer in
overspray will also be disposed of in landfill.
The notified polymer is not expected to be water-soluble and therefore will not be mobile in
either the terrestrial or aquatic compartments. As a consequence of its low water solubility,
the notified polymer is expected to eventually associate with the soil matrix and sediments.
Due to its high molecular weight and low water solubility the polymer is not expected to
bioaccumulate.
RECOMMENDATIONS
Regulatory controls
? The epoxy primer containing the notified polymer should be classified as follows
under the ADG Code:
- Class 3 (Flammable Liquid) and packaging group II
? Suppliers should label the epoxy primer containing the notified polymer as a Class [3]
dangerous good with the signal word [Flammable].
Control Measures
Occupational Health and Safety
? Employers should implement the following engineering controls to minimise
occupational exposure to the notified polymer in spray paint products:
- Exhaust ventilation during paint make-up and cleaning of equipment
- Automated spray painting
- Enclosed spray painting booth with exhaust or filter system.
? Employers should implement the following safe work practices to minimise
occupational exposure during handling of the notified polymer in spray paint
products:
- Use of the paint containing the notified polymer should be in accordance with the
NOHSC National Guidance Material for Spray Painting
- Employers should ensure that NOHSC exposure standards for all of the
components of the final paint mix are not exceeded in the workplace
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
53
? Employers should ensure that the following personal protective equipment is used by
workers to minimise occupational exposure to the notified polymer in spray paint
products:

14 PUBLICATION SUMMARY REPORT
SV93
Summary Report
Reference No: PLC/274
MBT (Australia) Pty Ltd of 11 Stanton Rd Seven Hills NSW 2147 (ABN 46 000 450 288)
has submitted a synthetic polymer of low concern (PLC) notification statement in support of
their application for an assessment certificate for SV93. The notified polymer is intended to
be used as a component of an additive to concrete. Less than 10 tonnes of the notified
polymer will be imported per annum for each of the first five years.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
The notified polymer was found to have very low acute oral toxicity, to be non-irritant to skin
and a minimal irritant to eyes, and non-mutagenic in a bacterial reverse mutation assay. It is
not expected to cross biological membranes, and systemic toxicity effects are not expected.
Based on the data provided by the notifier, the notified polymer is not classified as a
hazardous substance in accordance with the NOHSC Approved Criteria for Classifying
Hazardous Substances.
Occupational Health and Safety
Dermal exposure to the imported products which contain < 2 % notified polymer may occur
due to contact with drips and spills of the products during reformulation or addition to
concrete. Exposure to the reformulated product containing a lower proportion of notified
polymer may also occur during addition to concrete. There may also be dermal exposure to
the concrete containing less than 0.01 % notified polymer. Exposure at this point will be very
low due to the protective measures used to prevent contact with the fresh concrete.
Based on the low toxicological hazard presented by the notified polymer, the low
concentrations present at all points, and the protective equipment specified in the MSDS
(gloves, safety goggles and industrial clothing), the notified polymer will present a low risk to
occupational health and safety.
Public Health
The only significant public exposure is limited to concrete purchased by do-it-yourself
handymen for such application as residential driveways. This will be limited to dermal
exposure. The notified polymer is not a dermal irritant in rabbits. Based on the above
information the notified polymer is unlikely to pose a significant risk to public health.
Environmental Effects
The majority of the notified polymer will be immobilised in the matrix of the concrete
fabrications in which it is used and will not pose a significant risk to the environment.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
55
Formulation of the concrete admixture containing the notified polymer occurs through a
process that minimises environmental release of the notified polymer and includes recycling
of water used to wash residue from empty import containers and admixture plant equipment.
The water used to wash admixture transport tankers is also recycled back into the formulation
process.
At the concrete plants the notified polymer is used at a low concentration in concrete. Waste
generated during the cleaning of plant equipment and ready-mix concrete trucks along with
the excess concrete is allowed to harden before disposal to landfill. Therefore concrete waste
containing the notified polymer is not likely to pose a hazard to the environment because the
polymer will be immobilised in the matrix of this material.
There is potential for a small amount of notified polymer to be released to the environment as
a consequence of spillage and leakage of hoses at the admixture plant. This release would be
to waste water since the notifier states that this material would be washed into a holding pit
connected to the on-site treatment plant. The notified polymer is likely to adsorb to waste
water sludge at the on-site treatment plant thereby significantly reducing its release to the
sewer. If some of the notified polymer leaches into water the risk to the aquatic environment
would be low due to the high molecular weight of the notified polymer and its limited
toxicity to aquatic organisms.
RECOMMENDATIONS
Control Measures
Occupational Health and Safety
? Employers should ensure that the following personal protective equipment is used by
workers to minimise occupational exposure to the notified polymer as introduced:
- impermeable gloves, safety goggles, industrial clothing.
Guidance in selection of personal protective equipment can be obtained from
Australian, Australian/New Zealand or other approved standards.
? A copy of the MSDS should be easily accessible to employees.
? If products and mixtures containing the notified polymer are classified as hazardous to
health in accordance with the NOHSC Approved Criteria for Classifying Hazardous

15 PUBLICATION SUMMARY REPORT
Copolymer in Foraperle 321
Summary Report
Reference No: EX/32
Elf Atochem (Australia) Pty Ltd (now Atofina (Australia) Pty Ltd) of 270-280 Hammond
Road Dandenong SOUTH VIC 3175 has submitted a limited notification statement in support
of their application for an assessment certificate for Copolymer in Foraperle 321. The
notified polymer is intended to be used as a water repellant for paper products and protective
coating for concrete products. It is estimated that greater than one tonne of the notified
polymer will be imported per annum for each of the first five years.
Since granting of the abovementioned Assessment Certificate, International Sales and
Marketing Pty Ltd of 55 Halstead Street South Hurstville NSW 2221 (ACN No. 36-467-259-
314) has submitted a notification statement in support of their application for an extension of
the original Assessment Certificate for Copolymer in Foraperle 321. Atofina (Australia) Pty
Ltd has agreed to this extension. Information submitted by Atofina Australia Pty Ltd indicate
that the use pattern remain the same as those assessed in NA/588.
The notifier, International Sales and Marketing Pty Ltd intends to import the notified
polymer, in the product Tegosivin HE 503, at an additional amount of 25 kg per annum for
use on concrete, clay and terracotta.
ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS
Hazard Assessment
Foraperle 321 containing the notified polymer was of low acute oral toxicity (LD50 > 2 000
mg/kg), was not a skin irritant or sensitiser, but was slightly irritating to rabbit eye. On the
basis of the toxicology data provided, Foraperle 321 would not be classified as hazardous
according to NOHSC Approved criteria for Classifying Hazardous Substances.
Occupational Health and Safety
The risk of occupational health and safety effects posed to transport workers, who will be
handling unopened containers of the product containing the notified polymer, is low.
Workers in the paper industry may be exposed to solutions containing up to 30% of the
notified polymer by dermal, ocular and inhalation routes during paper production phases, that
is, internal and external treatment of paper and paper products. Little information was
provided by the notifier on these processes. Although not classifiable as an eye irritant,
ocular exposure to Foraperle 321 may cause immediate irritation should eye contact occur.
The notifier indicates that workers at the paper mills will be required to wear eye protection,
gloves and overalls. Given that the results of a skin sensitisation and irritation study
conducted on Foraperle 321 were negative, and that dermal absorption of the polymer is
unlikely because it has a high molecular weight, the risk of workers experiencing acute health
effects from handling the notified polymer is low.
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
58
No data on inhalation toxicity has been provided. However, the notifier states that local
exhaust ventilation systems are in place in paper production areas, which will serve to control
inhalation exposure and therefore any potential health effects via this route of exposure.
Dermal exposure is the primary route of exposure to the notified polymer for workers in the
building industry. However, the risk of occupational health effects for these workers is low,
given the results of toxicological studies submitted by the notifier.
Foraperle 321 also contains N-methyl-2-pyrrolidone (NMP) and acetic acid. NMP is readily
absorbed through the skin and is also a skin and eye irritant (R36/38). These risk phrases are
incorporated on the Foraperle 321 label. NOHSC has not established a national exposure
standard for NMP. Acetic acid has a NOHSC exposure standard of 10 ppm or 25 mg/m3
(TWA) and 15 ppm or 37 mg/m3 (STEL). Employers are responsible for ensuring that the
exposure standard is not exceeded in the workplace. As inhalation exposure to and dermal
absorption of these components may occur in the workplace, workers should wear personal
protective equipment as indicated in the Recommendations of this report. These outline the
special glove requirements as given in the Foraperle 321 Material Safety Data Sheet (MSDS).
For the use of the notified polymer in Tegosivin HE 503 as a hydrophobing agent for
concrete, clay and terracotta, no significant risk to worker health and safety is expected. This
is based on the expected low hazard of the polymer and the very low concentration of
polymer in the product as applied.
Public Health
Where the product is sold to the public for application in the home, the primary hazards
associated with this application will, based on the limited data available, relate to the content
of NMP in Foraperle 321, rather than the notified polymer. The skin and eye irritancy of
NMP has prompted consideration of this compound for inclusion in the Standards for the
Uniform Scheduling of Drugs and Poisons (SUSDP) by the National Drugs and Poison
Scheduling Committee (NDPSC) at its February 1998 meeting. The NDPSC has included
this compound in the SUSDP in Schedules 6 and 5 and have additionally classified it as a
designated solvent. At the concentration of NMP used in Foraperle 321 the preparation will
require labelling as a Schedule 5 poison.
Based on the use pattern of the notified polymer and its physico-chemical and toxicological
properties, the copolymer in Foraperle 321 is considered not to pose a significant risk to
public health.
Environmental Effects
The main environmental exposure of the notified polymer will be through its major use to
treat paper products. Some environmental exposure will also occur when the polymer is used
in a minor way as a protective coating for concrete. In both these cases the polymer will be
adsorbed onto a substrate and will essentially be inert. The polymer is water soluble and
hence potentially mobile in landfill. However, it will remain bound to the paper matrix or
onto the surface of clay minerals in soil and be immobile. Both applications to pulp
suspension during paper manufacture and recycling of paper treated with the notified polymer
may result in a low level of discharge with wastewater of the polymer from treatment plants.
Based on limited information, the polymer is moderately toxic to daphnia and bacteria and is
Chemical Gazette Commonwealth of Australia Gazette
No. C2, 5 February 2002
59
of a type which is known to be toxic to algae. However, at the proposed levels of import the
discharge levels in pulp mill effluent and recycling plant effluent are well below expected
toxic levels. Hence the potential environmental hazard is low.
RECOMMENDATIONS
To minimise occupational exposure to Copolymer in Foraperle 321 the following guidelines
and precautions should be observed: safety goggles should be selected and fitted in
accordance with Australian Standard (AS) 1336 to comply with Australian/New Zealand
Standard (AS/NZS) 1337; industrial clothing should conform to the specifications detailed in
AS 2919 and AS 3765.1; impermeable gloves or mittens should conform to AS 2161.2. The
MSDS states that neoprene, polyvinyl chloride, natural rubber or butyl rubber gloves should
be worn. Spillage of the notified chemical should be avoided. Spillages should be cleaned
up promptly with absorbents which should be put into containers for disposal. Good personal
hygiene should be practised to minimise the potential for ingestion. A copy of the MSDS
should be easily accessible to employees.
Due to the presence of NMP and acetic acid in the product Foraperle 321, appropriate general
and exhaust ventilation should be employed in areas where the product is being handled in
undiluted form. There is a NOHSC exposure standard for acetic acid of 10 ppm or 25 mg/m3
(TWA) and 15 ppm or 37 mg/m3 (STEL). Employers are responsible for ensuring that this
level is not exceeded in the workplace.
The NDPSC has included this compound in the SUSDP in Schedules 6 and 5 and have
additionally classified it as a designated solvent. At the concentration of NMP used in
Foraperle 321 the preparation will require labelling as a Schedule 5 poison.

26 CALL FOR INFORMATION FOR NICNAS PEC EXPOSURE STANDARD
REVIEW
The National Occupational Health and Safety Commission (NOHSC) is considering
recommendations to review specific exposure standards. The recommendations are
contained in Priority Existing Chemical (PEC) reports prepared by the National Industrial
Chemicals Notification and Assessment Scheme (NICNAS).
Exposure standards are guides to the safe use of chemicals in the workplace. The proposed
standards give details on the acceptable concentration of substances in the worker's breathing
zone, to limit the risk of adverse health effects. Information on the National Exposure
Standards database can be found at:
http://www.nohsc.gov.au/OHSInformation/Databases/ExposureStandards/expsearch.asp
NOHSC is providing an opportunity for interested parties to supplement the information
contained in the PEC reports. Information in the reports and any material provided in
response to this request will be used to assist NOHSC in deciding if a review of the exposure
standard is required and, if so, the priority of that review and the appropriate review
methodology. NOHSC's arrangements for initiating and conducting reviews are set out in
Process to Review and Update the National Exposure Standards, which can be found at:
