1 PUBLICATION SUMMARY REPORT
Luvimer 100P
Summary Report
Reference No: NA/557
BASF Australia Ltd of 500 Princes Highway Noble Park VIC 3174 (ACN 008 437 867) has
submitted a limited notification statement in support of their application for an assessment
certificate for Luvimer 100P. The notified polymer is intended to be used as a film forming
agent in the production of hair care products. Less than 20 tonnes of the notified polymer
will be imported per annum for the first five years.

ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS

The notified polymer was of very low acute oral and inhalation toxicity. It was neither an eye
irritant nor a skin sensitiser but a slight skin irritant. The notified polymer was not mutagenic
in an Ames test. On the available data, the notified polymer is not classified as a hazardous
substance according to the NOHSC Approved Criteria for Classifying Hazardous Substance.

The material safety data sheet (MSDS) for Luvimer 100P states that inhalation of the product
may result in slight respiratory irritation.

Occupational Health and Safety

There is little potential for significant occupational exposure to the notified polymer in the
transport and storage of the polymer and the hair spray products containing the polymer.

The notified polymer is imported in the form of a powder and formulated into hair care
products in Australia. The equipment used for formulation and filling of the notified polymer
to produce the finished product is enclosed and automated, the occupational exposure to the
chemical during these processes is low. However, dermal and/or inhalation exposure may
occur during manual operations of weighing and transferring the powder into the mixing
tank. Industrial control measures including local exhaust ventilation should be included in
the weighing area and in the vicinity of the formulation tanks. Appropriate personal
protective equipment such as overalls, protective gloves, safety glasses/chemical goggles and
face shield should be worn. A respirator will be required if breathable dust is formed. The
MSDS warns not to breath dust. Under these control measures, the risk of adverse health
effects resulting from exposure to the polymer at the formulation and packaging sites is
expected to be low.

Laboratory workers will be exposed to small quantities of the notified polymer for short
periods by dermal contact and inhalation exposure. Exhaust ventilation and personal
protective equipment should be available. The risk of adverse health effects resulting from
exposure to the polymer for laboratory workers is expected to be low.

Occupational use of the finished products in the hairdressing industry may result in dermal
and inhalation exposure to the notified polymer. A higher than normal incidence of
respiratory complaints (lung disease and respiratory irritation and asthma) is found among
workers in the hairdressing industry. The exact chemical cause cannot be determined in all
cases, however the inhalation of aerosol droplets from hair sprays is believed to be a


Chemical Gazette Commonwealth of Australia Gazette
No. C 7, 2 July 2002

6


contributing factor. Hair dressing industry workers would be expected to have much more
frequent exposure than members of the general public using the same formulation.
Employers in the hairdressing industry should take precautions to minimise inhalation of
spray products, e.g. by providing adequate ventilation for workers and the public. The
relevant State or Territory industry guidelines or codes of practice should be observed.

Public Health

Hair care products, including hair spray, will be available to the public and there may be
significant public contact with the notified chemical. The toxicity of the notified chemical is
low, and the high molecular weight makes it unlikely to cross biological membranes. The
use of the notified chemical in hairspray is unlikely to lead to extensive skin contact, and
therefore the potential for skin irritation from use of the notified chemical is minimal. The
risk to the public from this use of the notified polymer is considered to be negligible.

Environmental Effects

The environmental hazard from the notified polymer is considered to be low.

Almost all the imported material will be eventually released into sewers, diffuse and
Australia-wide, with the global Predicted Environmental Concentration (PEC) in sewage
estimated as a maximum of 20 礸/L. The polymer is likely to have high affinity for calcium
and magnesium ions in the environment, and when released via sewage would become
associated with the organic component of soils and sediments. It is unlikely to be mobile in
these media and is expected to undergo slow biodegradation to water and carbon dioxide
and/or methane. A maximum of 2 tonnes of polymer per year may also be placed into
landfill within partially emptied spray cans. When released, it is expected to associate with
soils and clay and slowly degrade through biological and abiotic processes.


Little of the polymer is expected to be released to receiving waters, and although water
soluble/dispersible anionic polymers containing a high proportion of carboxylate groups may
exhibit toxicity to green algae through chelation of certain divalent ions such as Ca2+ and
Mg2+ which are required as micronutrients by the algae, these toxic effects are expected only
in very soft water containing low concentrations of these ions. In harder waters containing
higher concentrations of divalent ion, and provided the release of the polymer is not
excessive it is expected that sufficient un-chelated metal ions will remain to satisfy the
nutrient requirements, so toxic effects would not be apparent. Since divalent calcium and
magnesium ions are usually present in most Australian receiving waters in considerable
concentration toxic effects from release of the polymer are not expected.

If any material were to reach the general water compartment and remain unassociated with
metal ions, the high molecular weight and affinity for water would preclude bioaccumulation.
Ultimately the polymer would become associated with metal ions and eventually become
assimilated into sediments.

RECOMMENDATIONS

To minimise occupational exposure to Luvimer 100P 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
3765.2; impermeable gloves should conform to AS/NZS 2161.2; all occupational
footwear should conform to AS/NZS 2210; respirators should conform to AS/NZS
1715 and AS/NZS 1716 and other internationally acceptable standards;

? Employers should ensure that the NOHSC exposure standard for inspirable dust of 10
mg/m3 is not exceeded in the workplace during formulation;

? Dust masks should be used by formulation workers if local exhaust ventilation is not
in place;

? Spillage of the notified chemical should be avoided. Spillages should be cleaned up
promptly with absorbents which should be put into containers for disposal;

? A copy of the MSDS should be easily accessible to employees.

? Hairdressers should work in accordance with the relevant State or Territory guidelines
or codes of practice;

If products containing the notified chemical are hazardous to health in accordance with the
NOHSC Approved Criteria for Classifying Hazardous Substances, workplace practices and
control procedures consistent with State and territory hazardous substances regulations must
be in operation.

2 PUBLICATION SUMMARY REPORT
Collacral VAL
Summary Report
Reference No: NA/914
BASF Australia Ltd (ABN 62 008 437 867) of 500 Princes Highway Noble Park VIC 3174
has submitted a standard notification statement in support of their application for an
assessment certificate for Collacral VAL, a synthetic polymer with NAMW < 1000. The
notified polymer is intended to be used as a thickener and stabiliser for polymer dispersions
and other aqueous systems for waterproofing membrane formulations. The notified polymer
will be reformulated at two sites in NSW and Victoria to produce the formulations, which
will be used throughout Australia. A quantity in the range of 1 to 10 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 available data the notified polymer is not classified as hazardous under the
NOHSC Approved Criteria for Classifying Hazardous Substances.

Occupational Health and Safety

There is Low Concern to occupational health and safety under the conditions of the
occupational settings described.

Public Health

There is Negligible Concern to public health when used for industrial reformulation and
application as described in the notification.

Environmental Effects

The low environmental exposure, combined with the low toxicity of the polymer indicates the
polymer is not likely to pose a risk to the environment based on its reported use pattern.

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 during
reformulation:
- impervious gloves, safety eyewear and industrial clothing and footwear

Dow Corning 8813 Polymer
Summary Report
Reference No: NA/936
Dow Corning Australia Pty Ltd of 3 Innovation Road, North Ryde, NSW 2113 (ABN 36 008
444 166) has submitted a limited notification statement in support of their application for an
assessment certificate for Dow Corning 8813 Polymer. The notified polymer is intended to be
used as a textile softener. Up to 10 tonnes/year will be imported for the first 5 years.

ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS

Hazard Assessment

Extrapolating from the analogue toxicity studies, notified polymer is predicted to be of very
low acute oral toxicity in rats. It could be a slight eye and skin irritant but not a skin
sensitiser. Evidence of mutagenicity is unlikely to be found in bacteria with and without
metabolic activation. Based on available information, the notified polymer is not classified as
a hazardous substance according to NOHSC Approved Criteria for Classifying Hazardous
Substances.

Occupational Health and Safety

The notified polymer will be imported as a polymer fluid containing approximately 100%
polymer. The occupational health risk posed to waterside, warehouse and transport workers is
negligible, unless exposure to the notified polymer occurs accidentally, when respiratory,
skin and eye protection would be needed for workers cleaning up spillage.

The polymer fluid will be supplied to textile chemical formulators who will prepare aqueous
emulsions containing 2-20% of the notified polymer. These emulsions will be further
blended/diluted by the addition of water, dyes and other agents before being applied to
textiles. At this stage the notified polymer will be present at 1-2%. Emulsification and
blending are largely automated which will minimise the potential for exposure to the notified
polymer. However, initial manual decanting of drums of polymer fluid and emulsions is
required and this is accompanied by the possibility of spillage and dermal and ocular
exposure of workers.

Given the toxicity profile of the notified polymer, if skin or eye contact occurs, irritation is
likely. Therefore, when workers are decanting the notified polymer or polymer emulsions,
appropriate measures must be taken to minimise exposure by the dermal, ocular and
inhalation routes. Local exhaust ventilation should be provided during transfer and mixing
processes and overalls, goggles and gloves should be worn. The polymer is likely to be
acutely toxic by inhalation, so the generation of aerosols should be avoided. The provision of
local exhaust ventilation is essential to prevent a health risk to workers during the transfer
and mixing processes and when handling treated, undried fabric.

Textiles treated with the notified polymer will be cured in drying ovens. During curing,
harmful degradation products may be released eg. formaldehyde. The notified polymer will
be present at low concentrations when it is applied to textiles and drying ovens should be

No. C 7, 2 July 2002

11


fitted with forced ventilation. Adequate ventilation during the drying and curing process is
required to ensure a low health risk to workers from possible exposure to polymer vapours
and degradation products.

There is negligible health risk for workers handling dry textiles. The polymer will have
crosslinked during curing and is reported to be bound irreversibly to the textiles.

Public Health

Public exposure will arise via dermal contact with fabric treated with the dried notified
polymer as a textile softener in articles of clothing. Given the low concentration of notified
polymer in the clothing fabric (up to 2%), the skin irritation hazard is likely to be low. There
will be minimal public exposure from transport, storage, reformulation and industrial use.

Environmental Effect

The majority of the notified polymer will be used to treat textiles which will ultimately be
disposed of in landfill. It is unlikely that the notified polymer will leach from the textile due
to its low water solubility, however, if it did it would become associated with the soil matrix
and not leach into the aquatic compartment. Wastes generated from the cleaning of
formulation machinery will be released into the sewer. Here, the notified polymer will adsorb
onto sediments due to its expected low water solubility. Some wastes containing the notified
polymer, those advanced water treatment plants, may be incinerated producing water vapour
and oxides of carbon and silicon. Some sludge containing the notified polymer will be
disposed of in landfill, where it is expected that the polymer would become associated with
the soil matrix and will not leached from the soil because of its expected low solubility in
water.

Polydimethylsiloxanes are unstable in landfill and on dry sediments because under dry
conditions, clay minerals catalyse their hydrolytic decomposition to smaller molecules, some
of which may be volatile and enter the atmosphere. However, when released to the
atmosphere, low molecular weight organosilanes are apparently rapidly degraded through
photolysis. Therefore in landfill, the notified polymer would eventually degrade and as such
poses little risk to the environment.

Based on annual imports of up to 10 tonne/annum used at 5 sites across Australia and
assuming a 50% "pickup rate", the daily release per mill on a nationwide basis to receiving
waters is estimated to be 6.7 kg/day. The concentration at the Mill's treatment plant would
be 3.35 mg/L and the concentration at the water treatment works would be 13.4 礸/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 local Predicted Environmental Concentration (PEC)
for the city mill is around 1.34 ppb. Similar calculations for a country mill estimates a worst
case of 0.31 ppm.

The ecotoxicity data indicates the notified polymer is not toxic to Daphnia up to the limit of
its water solubility. The hydrophobic nature of the notified polymer indicates that most would
adsorb onto particles of sediment and sludge, and would therefore not remain in the water
compartment and be available for assimilation by aquatic organisms. Furthermore, Nabholz
et al. have pointed out that the interaction between this class of compound and the dissolved



Chemical Gazette Commonwealth of Australia Gazette
No. C 7, 2 July 2002

12


and suspended organic matter in natural waters can significantly mitigate toxicity of these
compounds through reducing effective exposure to sensitive organisms.

Therefore, the environmental exposure and overall environmental hazard from the notified
polymer is expected to be low.

RECOMMENDATIONS

Control Measures

Occupational Health and Safety

? Employers should implement the following engineering controls to minimise
occupational exposure to the notified polymer:
- Local exhaust ventilation must be provided during transfer and mixing processes.
- Ventilation should also be provided during the heat curing process to minimise
exposure to formaldehyde vapour.

? Employers should implement the following safe work practices to minimise
occupational exposure during handling of the notified polymer:
- Spills should be dealt with in accordance with local, State, and Federal
regulations. Residues require the use of steam, solvents or detergents to remove
the slip hazard associated with silicones
- The polymer is likely to be acutely toxic by inhalation, so the generation of
aerosols should be avoided.

? Employers should ensure that the following personal protective equipment is used by
workers to minimise occupational exposure to the notified polymer:
Protective eyewear
Chemical resistant industrial clothing
Footwear
Impermeable gloves
Where engineering controls and work practices do not reduce vapour exposure to safe
levels, an organic vapour respirator should be used in addition to the personal
protective equipment indicated above.

Guidance in selection of personal protective equipment can be obtained from
Australian, Australian/New Zealand or other approved standards.

? Atmospheric monitoring should be conducted to measure workplace concentrations
during formulation and use of the notified polymer. Employers should ensure that
NOHSC exposure standards for formaldehyde are observed.

? 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 Section 64(1) of the Act;
- If the notified polymer is used in a manner that may generate aerosols, acute
inhalation toxicity data must be provided for assessment.
or

(2) Under Section 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.

2-cyclohexylidene-2-phenylacetonitrile (Peonile)
Summary Report
Reference No: NA/987
Givaudan Pty Ltd has submitted a standard notification statement in support of their
application for an assessment certificate for 2-cyclohexylidene-2-phenylacetonitrile (Peonile).
The notified chemical is intended to be used as an aroma in alcoholic perfumery, cosmetics,
toiletries, household products, soaps, detergents and industrial perfumery. Less than one
tonne 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 findings of an acute oral toxicity study, the notified chemical meets the NOHSC
Approved Criteria for Classifying Hazardous Substance as Harmful (Xn) by the oral route
(R22 ?Harmful if Swallowed).

Occupational Health and Safety

The intermediate product containing the notified chemical is added by the operator to an open
batch processing system. However, the notified chemical has low dermal toxicity and is
present in the product at a maximum concentration of 10%. Providing appropriate operating
procedures are adopted, the probability of exposure to the chemical is low and the health risk
to workers is minimal. The risk to workers in handling the finished products containing 0.2%
or less of the notified chemical is very low.

Public Health

The general public will be repeatedly exposed to a very low level of the notified chemical via
a number of different consumer products (perfumes, soaps, detergents or softeners). The
routes of exposure will mainly be dermal and inhalation. Given the low levels of the notified
chemical in the end-use products, and their use patterns, the risk to the public health is
considered to be low.

Environment Effects

The new chemical will be used as a fragrance ingredient of domestic cleaning and personal
care formulations, and most will eventually be released into domestic sewage systems as a
consequence of product use. The compound is not readily biodegradable (0% over 28 days),
and has a high partition coefficient of 4, a moderate Log Koc of 3.42 and a low water
solubility (7.5 mg/L), all indicating that most of the material would eventually partition to
sediment. Here it is expected to slowly degrade to water and oxides of carbon and nitrogen
through biological processes.

The PEC/PNEC ratio for the aquatic environment, assuming nationwide use, is 0.006. This
value is significantly less than 1, indicating no immediate concern to the aquatic
compartment.


Chemical Gazette Commonwealth of Australia Gazette
No. C 7, 2 July 2002

15



The above considerations indicate minimal hazard to the environment when the new chemical
is used as a component of domestic products in the manner and levels indicated by the
notifier.

On the basis of the available information, the overall environmental hazard of the notified
chemical is expected to be low.

RECOMMENDATIONS

Regulatory controls

? The NOHSC Chemicals Standards Sub-committee should consider the following
health hazard classification for the notified chemical:
- R22 Harmful if swallowed

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 chemical
Coveralls, gloves and glasses.

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 Peonile 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.

Disposal

? The notified chemical should be disposed of into the sewer or landfill.

Emergency procedures

? Spills/release of the notified chemical should be contained as described in the MSDS
(i.e. covered with inert material and transferred to a sealable waste container) and the
resulting waste disposed of in landfill.

Secondary Notification

The Director of Chemicals Notification and Assessment must be notified in writing within 28
days by the notifier, other importer or manufacturer:

5 PUBLICATION SUMMARY REPORT
Chemical in RX 3211
Summary Report
Reference No: NA/998
BASF Akzo Nobel Automotive OEM Coatings Pty Ltd (ACN 092 127 501) & Akzo Nobel
Pty Ltd (ACN 000 119 424) of 51 McIntyre Road Sunshine VIC 3020 have submitted a
standard notification statement in support of their application for an assessment certificate for
Chemical in RX 3211. The notified chemical is intended to be used as a component of an
automotive primer. Up to 50 tonnes of the notified chemical will be imported per annum for
the first five years.

ASSESSMENT OF PUBLIC, OCCUPATIONAL HEALTH AND SAFETY AND
ENVIRONMENTAL EFFECTS

Hazard Assessment

No toxicity studies on the notified chemical are available. The notifier provided toxicity
reports on the analogue Vestanat B 1358/100. Vestanat B 1358/100 was of low acute oral
toxicity in rats. It was neither a skin irritant nor a skin sensitiser but a slight eye irritant.

The notifier also provided some toxicity information on two related substances, an isocyanate
and a blocking agent. Both of them are on the NOHSC List of Designated Hazardous
Substances. The blocking agent is classified as Xi with R36 (Irritating to eyes) and R43 (May
cause sensitisation by skin contact). In addition, EU have added R40(3) (Carcinogen
Category 3, Harmful) to the blocking agent. The isocyanate is classified as Toxic with R23
(Toxic by inhalation), and Xi with R36/37/38 (Irritating to eyes, respiratory system and skin)
and R42/43 (May cause sensitisation by inhalation and skin contact). NOHSC has established
a national exposure standard for all isocyanates (as-NCO), and listed isocyanates on Schedule
3, `Hazardous substances for which health surveillance is required'.

Based on the toxicity data of the analogue and the expected lower toxicity compared to the
related substances, the notified chemical is expected to be of low acute oral, dermal and
inhalation toxicity. It would not be a skin irritant or skin sensitiser but may be a slight eye
irritant. Based on the information provided, the notified chemical cannot be classified as a
hazardous substance according to the NOHSC Approved Criteria for Classifying Hazardous
Substances.

The notifier classified RX 3211 as a hazardous substance with Dangerous Goods Class 3. The
Material Safety Data Sheet (MSDS) for RX 3211 states that it is harmful if swallowed and
may cause irritation to nose, throat and gastrointestinal tract, eyes and skin. Chronic
inhalation of excessive concentrations of vapours may produce effects on the central nervous
system. These effects are based on the effects of organic solvents in RX 3211.

For some chemicals in the finished emulsion, NOHSC has allocated exposure standards for
methyl isobutyl ketone (TWA 50 ppm or 205 mg/m3, STEL 75 ppm or 307 mg/m3), 2-
butoxyethanol (TWA 25 ppm or 121 mg/m3) and nitric acid (TWA 2 ppm or 5.2 mg/m3,
STEL 4 ppm or 10 mg/m3).

Occupational Health and Safety

Chemical in RX 3211 will be manufactured in Australia or imported from overseas. RX 3211
will be formulated into aqueous emulsion and finished emulsion at the notifier's facility, and
then applied as a component in the automotive primers at the car manufacturing sites.

The notified chemical is transported in containers during importation and distribution. The
potential for exposure to the notified chemical during transport and storage would be
considered low and would only be envisaged following accidental puncture of the containers.
Therefore the health risk for transport workers is assessed as low.

Exposure to the notified chemical for synthesis, formulation, maintenance and laboratory
workers at the formulation site may occur from contact with RX 3211 (80% notified
chemical) or aqueous and finished emulsions (<10% notified chemical). Fixed transfer lines
and enclosed vessels are used in the synthesis and formulation processes. In addition,
ventilation systems are equipped in the workplaces. Given these engineering controls and
likely low systemic toxicity of the notified chemical, the overall health risk for workers
involved in synthesis and formulation is assessed as low. PPE worn by the workers includes
chemical resistant gloves, overalls, goggles, and organic vapour respirators.

At the car manufacturing sites, the finished emulsion containing the notified chemical will be
mixed in a storage tank, which will be used to coat automotive bodies by dipping. At this
point, exposure to diluted notified chemical (<1%) 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 chemical, the
health risk to these workers involved in painting process 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 chemical is essentially
unavailable for absorption and thus the health risk to workers from the notified polymer after
paint curing would not be significant.

Public Health

In its application, the notified chemical is a bound component of the primary coating of
vehicle body work and is not accessible to human contact. The primary coating is ultimately
covered by several other coats of paint and contact with the notified chemical is further
prevented. The low likelihood of exposure to the notified chemical and the low toxicity of the
notified chemical suggest that it will not pose a significant hazard to public health when used
as proposed.

Environmental Effects

The notified chemical will be used as a component in a primer coating for cars.
Consequently, most of the chemical will be reacted into the inert, primer matrix upon curing.
The metal panels coated with the primer are likely to be either recycled for steel reclamation
or placed into landfill at the end of their useful life. When recycled the chemical would be
destroyed in blast furnaces.



Chemical Gazette Commonwealth of Australia Gazette
No. C 7, 2 July 2002

Approximately 360 kg of chemical waste may be generated during manufacturing,
formulation, and application of the primer product each year. These wastes will largely be
disposed of in landfill where the chemical may leach into the water compartment due to its
moderate water solubility and will undergo slow degradation through both biotic and abiotic
processes. A small amount of the chemical waste generated each year, up to 60 kg, may be
released in waste water resulting in minimal release of the notified chemical to the sewer
after treatment on-site. As such the level of risk posed by use of the notified chemical is
expected to be low.


RECOMMENDATIONS

Control Measures

Occupational Health and Safety

No special precautions are required for the notified chemical; however, due to the presence of
hazardous components in the emulsions and final paint:

? Employers should implement the following engineering controls to minimise
occupational exposure:

- Enclosed fixed transfer lines for transfer operations;
- Enclosed mixing vessels;
- Exhaust ventilation during synthesis, formulation, quality control analysis, storage
and paint application;

? Employers should implement the following safe work practices to minimise
occupational exposure during handling of emulsions and final paint:

- NOHSC exposure standards for all of the components of the final paint mix should
not be exceeded in the workplace;

Summary Report
Reference No: PLC/263
BASF Wattyl Coatings Pty Ltd of 231-233 Newton Road, Wetherill Park NSW 2164
(ABN 93 080 438 464) has submitted a synthetic polymer of low concern (PLC) notification
statement in support of their application for an assessment certificate for ZK42-4912. The
notified polymer is intended to be used as a component of car re-finish paint. Fifteen 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 information has been submitted for the notified polymer. Therefore, the
substance cannot be assessed against 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 present a health hazard.

The imported product containing the notified polymer is classified as hazardous as a result of
the 2-butoxyethanol solvent content (20 ?43%) and is assigned the risk phrases R20/21/22 -
Harmful by inhalation, in contact with skin and if swallowed and R37 - Irritating to
respiratory system as the 2-butoxyethanol content is above the concentration cut-off of 20%.
The imported product also contains sec.-butanol which has been assigned risk phrases R36/37
- Irritating to eyes and respiratory system and R67 - Vapours may cause drowsiness and
dizziness and 2,4,7,9-tetramethyl-5-decine-4,7-diol which is assigned the risk phrase R36 -
Irritating to eyes according to the MSDS for the imported products. Therefore, the imported
products should be considered harmful by the standard routes of absorption, to be irritating to
eyes and respiratory system and to liberate vapours which may produce drowsiness and
dizziness. Exposure standards for sec.-butanol (100 ppm TWA) and 2-butoxyethanol (25 ppm
TWA) have been assigned.

Some of the imported A 90 products containing the notified polymer are classed as Class 3
dangerous goods (flammable liquid) because of the solvent content.

The MSDS for the A 90 product lists a number of potential health effects when exposed to
solvent vapour concentrations in excess of the occupational exposure limit, namely mucous
membrane and respiratory system irritation and adverse effects on kidney, liver and central
nervous system. Symptoms and signs include headache, dizziness, fatigue, muscular
weakness, drowsiness and in extreme cases, loss of consciousness. Skin defatting may also
occur on repeated exposure and absorption of 2-butoxyethanol (solvent) through the skin will
cause harmful effects on the blood.

Occupational Health and Safety

Exposure to the notified polymer during transport and storage is not likely to occur except in
the event of accidental spillage. The greatest exposure is in the mixing and spraying of the
paints.


Chemical Gazette Commonwealth of Australia Gazette
No. C 7, 2 July 2002

26


The final paint mix and the imported A 90 line containing the notified polymer could contain
a variety of additional ingredients that may introduce human health hazards. It is also
probable that a number of different paint formulations may be used. Therefore, the notified
polymer must be assessed for health hazards associated with the application of the paint.

The use of paint containing the notified polymer should be in accordance with the NOHSC
National Guidance Material for Spray Painting. To minimise exposure, all spray painting
procedures should be carried out inside a spray booth, utilising air supplied respirators if
necessary. Workers should be wearing recommended protective clothing to minimise dermal
exposure. Similar considerations apply in the cleaning of equipment, spills and disposal of
the polymer.

There is little potential for exposure once the paint mix has dried since the polymer is trapped
within the paint matrix.

There are NOHSC exposure standards for 2-butoxyethanol and sec.-butanol, listed as
ingredients in the A 90 tinter. The employer is responsible for ensuring that these exposure
standards are not exceeded in the workplace.

The products containing the notified polymer are flammable due to their solvent content.
Precautions must be taken to avoid sources of ignition.

The notified polymer itself is of low hazard, and apart from the controls stated above, no
additional controls are required.

Conclusion

The notified polymer is of low concern to human health and safety and no specific risk
reduction measures are necessary.

Public Health

The notified polymer is a component in car paint finishes which are only available to
industrial end users. The paint is applied in enclosed spray booths which filter any overspray
from the air. Although significant public exposure to painted cars is expected the notified
polymer is trapped within the paint matrix. Therefore the notified polymer is unlikely to pose
a significant threat to public health.

Environmental Effects

The notified polymer will be imported for use as a component in a variety of refinish car
paints. Consequently, most of the polymer will be incorporated in automotive paints, which
upon drying, will become inert. The metal panels coated with the polymer are likely to be
either recycled for steel reclamation or placed into landfill at the end of their useful life.
When recycled the polymer would be destroyed in blast furnaces.

A maximum 4.5 tonnes of notified polymer wastes may be generated in motor vehicle
workshops each year as a result of vehicle spray-painting. The paint product will be used in
workshops throughout Australia and therefore waste generation and disposal is expected to
occur in a diffuse manner. These wastes will be disposed of through licensed waste disposal

No. C 7, 2 July 2002

27


contractors most likely by incineration or in landfill. Incineration will destroy the polymer
producing water vapour and oxides of carbon and nitrogen. In landfill, the polymer is not
expected to leach into aquatic compartments via the soil environment because the polymer
will be disposed of in a cured and solidified form. In soil environments, the polymer will
undergo slow degradation through both biotic and abiotic processes.

Under normal usage, the notified polymer is not expected to enter the aquatic environment
and to pose a hazard to aquatic organisms. In the event of an accidental spill into the water
compartment, the polymer's large molecular size will prevent movement across biological
membranes and bioaccumulation. As such the level of risk posed by use of the notified
polymer is expected to be low.

RECOMMENDATIONS

Control Measures

No specific precautions are required to control exposure to the notified polymer. However, in
the interests of good occupational health and safety, the following guidelines and precautions
should be observed:

Occupational Health and Safety

Spillage of the notified polymer should be avoided. Spillages should be cleaned up
?br> promptly with absorbents which should then be put into containers for disposal;

days by the notifier, other importer or manufacturer:

(1) Under Section 64(1) of the Act; if
- the notified polymer is introduced in a chemical form that does not meet the PLC
criteria.
or

(2) Under Section 64(2) of the Act:

Polymer in HC-31-3586
Summary Report
Reference No: PLC/268

PPG Australia Pty Ltd of McNaughton Rd Clayton Victoria (ACN 82 055 500 939) has
submitted a synthetic polymer of low concern (PLC) notification statement in support of their
application for an assessment certificate for Polymer in HC-31-3586 Acrylic Resin. The
notified polymer will be used as a component in automotive refinish coatings for use on the
exterior of car bodies. Up to 50 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

No toxicological data has been provided on the notified polymer. Since the notified polymer
has a NAMW >1000 (NAMW= 4292 with 2.7%<100 and 0.9% <500) absorption across
biological membranes is expected to be restricted. As imported, the notified polymer is in a
solution containing up to 30% xylene, 30% light aromatic solvent naphtha and up to 10% n-
butyl acetate. The MSDS provided for the notified polymer indicates that ingestion of large
amounts of the product may cause nausea and inhalation of vapours may cause irritation to
the mucous membranes, headaches, dizziness and possible nausea. The products may also
cause skin and eye irritation. These effects are likely to be a result of exposure to solvents
rather than the notified polymer. The polymer meets the PLC criteria and is unlikely to be a
hazardous substance according to the NOHSC Approved Criteria for Classifying Hazardous
Substances.

Occupational Health and Safety

As the polymer itself is of low hazard, and controls are already in place to prevent exposure
to other paint components, and to the polymer in particulate form during spraying, therefore
the health risk due to the notified polymer is low, and no additional controls are required.

Public Health

The notified polymer is not available for sale to the general public and will be used as a
component of automotive paints. Since the notified polymer will be bound to the automobile
bodies in an insoluble polymeric matrix, the risk of exposure of the public to 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 and pose minimal risk
to the environment.

The notified polymer in liquid waste from spills, equipment cleaning, masking materials and
spray booths 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. Empty paint containers and solid wastes from spills and spray booths
will also be disposed of in landfill.

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

Occupational Health and Safety

? Employers should implement the following engineering controls to minimise
occupational exposure to the polymer in HC-31-3586 as diluted for use in paint
products:
- Use of the paint containing the notified polymer should be in accordance with the

- Appropriate local and general ventilation during formulation and application of
the fabric coating agents.

? Employers should ensure that the following personal protective equipment is used by
workers to minimise occupational exposure to the notified polymer supplied in the
butanone solvent:
- Laboratory coats, protective gloves and safety glasses for R&D and QC staff.
- Protective overalls, impermeable gloves, chemical goggles/face shields and
respiratory protection for workers involved in formulation and application of the
fabric coating agents.

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.

Disposal

? The notified polymer should be disposed of in landfill.

Emergency procedures

? Spills/release of the notified polymer should be contained, absorbed in vermiculite,
dry sand or earth, and the resulting waste disposed of in accordance with
State/Territory regulations.

13 PUBLICATION SUMMARY REPORT
PCTA 21427
Summary Report
Reference No: PLC/298

Eastman Chemical Limited of Level 8, 15 Talavera Road North Ryde NSW 2113 (ACN 72
001 313 417) has submitted a synthetic polymer of low concern (PLC) notification statement
in support of their application for an assessment certificate for PCTA 21427. The notified
polymer is intended to be used in the production of end-use products such as packaging
articles, injection-moulded parts and fibres. Twenty 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 substance meets the PLC criteria and is therefore unlikely to be a hazardous
substance in accordance with the Approved Criteria for Classifying Hazardous Substances.
Excessive heat and degradation of the polymer could cause odours and fumes in the
workplace. However, as this would also result in loss of usable product it is not expected to
be a common occurrence. There have been no reports of health conditions associated with
exposure to this polymer.

Occupational Health and Safety

Due to its low hazard and low potential for exposure during processing into plastic materials,
Polymer PCTA 21427 is of low risk to human health and safety and no specific risk reduction
measures are necessary.

Public Health

In view of its high molecular weight, physical and chemical properties, and its use pattern,
the notified polymer is unlikely to pose a significant risk to public health.

Environmental Effects

Only a small amount of waste will be generated during the processing of polymer pellets into
plastic products. This will be disposed of in landfill. Eventually all of the notified polymer
will be disposed of in landfill as domestic waste or incinerated. As a consequence of its
hydrophobic nature, the notified polymer is expected to associate with the soil matrix and
sediments and not be mobile in landfill where it will slowly degrade. Incineration of the
notified polymer will produce water vapour and oxides of carbon and nitrogen and sulphur.
Empty import containers will also eventually be disposed of in landfill.

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

No special control measures are required for the notified polymer, however, in the interest of
good occupational health and safety, the following measures are recommended:

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:
- The use of PPEs including safety glasses with side shields or goggles, gloves,
boots, dust masks and protective work clothing such as overalls or laboratory
coats is recommended

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.

Secondary Notification

The Director of Chemicals Notification and Assessment must be notified in writing within 28
days by the notifier, other importer or manufacturer:

20 AUSTRALIAN HIGH VOLUME INDUSTRIAL CHEMICALS LIST
STAGE II, IMPORTED CHEMICALS
In May 2001, as Stage I of the establishment of an Australian High Volume Industrial
Chemicals (HVIC) List, NICNAS released information regarding chemicals manufactured in
Australia in volumes 1000 tonnes per year. In December 2001, NICNAS released a call for
information on industrial chemicals imported to Australia in large quantities (see notice in
Chemical Gazette of 4 December 2001). This represents Stage II of the establishment of the
Australian HVIC List.

Companies importing industrial chemicals in volumes 100 metric tonnes per year between
1999 and 2001 were required to submit information regarding chemical identity, the volumes
imported and general uses of the chemicals.

Collation of information received on imported chemicals is nearing completion. There are a
small number of chemicals for which information is still outstanding.

Of the 642 responses received,

594 industrial, reportable chemicals were imported at 100 tonnes per year with 214
?br> imported at 1000 tonnes per year;

224 (35%) companies import industrial, reportable chemicals at 100 tonnes per
?br> year.

Chemicals for which the summed, total imported volume to Australia is 1000 tonnes per
year are listed below.

The data for imported chemicals will be combined with data for manufactured chemicals
(collected in Stage I) to produce an Australian HVIC List, which will include aggregate
quantities reported in bands (eg. 1,000-9,999 tonnes) and additional information such as the
industries in which the chemicals are used and use categories.

Should you require any further information, queries can be directed to Dr Graham Harvey by
phone on (02) 8577 8851, fax: (02) 8577 8888 or email: graham.harvey@nicnas.gov.au.

21 CANDIDATE LIST OF CHEMICALS
The updated Candidate List of chemicals along with the Standby section of the List was published in
the Chemical Gazette of 7 August 2001.
Chemicals contained in the standby section of the Candidate List were reviewed in June 2002 to
determine whether the awaited data has become available. Where new information has come to hand
this has been reviewed and the status of all the chemicals on the List redetermined.
Table 1 gives the Candidate List of chemicals following the review of the standby section. The
Candidate List will be used by NICNAS as a basis for selecting chemicals from time to time for
declaration and assessment as priority existing chemicals. Some chemicals from the Candidate List
have been declared as Priority Existing Chemicals and hence no longer appear on the Candidate List.
Table 2 gives the chemicals remaining on the Standby section of the List following the review. This
list will be reviewed periodically and chemicals transferred to the main section of the Candidate List
or the Not Selected List depending on the outcomes of awaited assessments and/or testing.
Table 3 lists the chemicals moved from the main or standby sections of the Candidate List in the
current review and the reasons for the change.

22 NICNAS EXISTING CHEMICALS PROGRAM
CONSULTATION ON PROPOSED PRIORITY EXISTING CHEMICALS
The NICNAS Candidate List of chemicals for possible assessment has been updated and is
published in a separate notice in this edition of the Chemical Gazette. Chemicals from this
Candidate List are selected from time to time, for assessment as Priority Existing Chemicals
(PEC).

NICNAS is considering the assessment of chemicals listed below and is seeking comments
from any person or organisation on the proposed assessments. Data on health and
environmental effects or exposure are not being requested at this time, only comments on the
proposal to conduct assessments of these chemicals are being sought. Comments are also
sought on the proposal to assess all the chromium compounds listed below. It is proposed
that a full risk assessment ?health, environment and public health- would be undertaken.

Methylene chloride (CAS No 75-09-2)
Methylene chloride is imported in high volumes, approximately 5000 tonnes, into Australia.
It is used in a wide variety of applications such as degreasing agents, strippers, in paints and
adhesives as a thinner and in industrial oils. It is also used in urethane foam manufacturing
and as a solvent for bitumen resins. Health concerns have been raised for methylene
chloride, particularly its use in confined spaces.

Chromium VI compounds
Chromium VI compounds including:
Ammonium chromate CAS No 7788-98-9
Ammonium dichromate CAS No 7789-09-5
Potassium chromate CAS No 7789-00-6
Potassium dichromate CAS No 7778-50-9
Sodium chromate CAS No 7775-11-3
Sodium dichromate CAS No 10588-01-9
Chromium trioxide CAS No 1333-82-0
Calcium chromate CAS No 13765-19-0
Lead chromate CAS No 7758-97-6
Strontium chromate CAS No 7789-06-2
Zinc chromate CAS No 13530-65-9

A total of approximately 1200 tonnes of various chromium VI compounds are imported into
Australia. Chromium VI compounds are used in electroplating, printing, galvanizing, in
timber preservation and in paints. New data on the carcinogenic effects of chromium VI
compounds in humans have become available.

24 COMMENT ON DRAFT NATIONAL LIST OF EXEMPTIONS TO THE
PROHIBITION ON THE WORKPLACE USE OF CHRYSOTILE ASBESTOS
The National Occupational Health and Safety Commission (NOHSC) invites public comment
on the proposed exemptions to the prohibition on the workplace use of chrysotile asbestos.

In 2001, NOHSC declared, and the Workplace Relations Ministers' Council endorsed, a
prohibition on the workplace use of chrysotile asbestos in Australia. The prohibition will take
effect simultaneously under regulations in each Australian occupational health and safety
jurisdiction by no later than 31 December 2003.

All uses of chrysotile asbestos, including the replacement of chrysotile products when
replacement is necessary, are prohibited except for (a) bona fide research or analysis,
including museum display and historical collections and testing for asbestos fibres (b) for
removal or disposal, (c) where it is encountered during non-asbestos mining, (d) where there
is another specified exception, or (e) for chrysotile products in situ, including its disposal and
replacement with non-chrysotile components, when the prohibition takes effect.

A limited range of exemptions may be considered, for example, where alternative products
do not exist or where their use would create greater risks than the corresponding chrysotile
product. A national list has been drafted, which has identified four situations where
exemptions may apply and, in relation to each, identifies the length of time that they are
available and the basis on which they have been established. The United Kingdom's (UK)
exemptions are the basis for the Australian exemptions with modifications mainly to remove
UK exemptions of products for which there are no known uses in Australia. Only items on
the National List of Exemptions will be exempted, and where items on the list are subject to
border controls, they will be included in Customs regulations.

A Public Discussion paper providing a description of the process used to develop the
National List of Exemptions is available free of charge by downloading from the NOHSC
Website at: http://www.nohsc.gov.au/NewsAndWhatsNew/MediaReleases/mr-280602.htm

Alternatively, if you wish to have a downloaded copy sent to you, place your request by:

? telephone to Freecall 1800 666 843 ?follow the prompts when the call is answered;
or
? fax (02) 6279 1150 ?mark your fax `National List of Exemptions for Chrysotile
Asbestos' and include your name and postal address; or
? email to joanne.cuthbert@nohsc.gov.au ?title your email `National List of
Exemptions for Chrysotile Asbestos' and include your name and postal address.

NOHSC will review the National List of Exemptions in light of public comment received
and make a final recommendation at its October 2002 meeting. Following agreement by
NOHSC, and subject to endorsement by Workplace Relations Ministers' Council, the
presence of chrysotile products on the finalised National List of Exemptions will be the
mechanism through which Commonwealth, State and Territory Governments will allow the
workplace use of these products in their jurisdiction, and, where relevant, to permit their
importation and exportation under Customs regulations.

Public comment closes on 13 September 2002.

25 PROPOSED ADDITION OF ACTINOLITE, ANTHOPHYLLITE, AND
TREMOLITE ASBESTOS TO SCHEDULE 2, "SUBSTANCES PROHIBITED FOR
SPECIFIED USES", OF THE NATIONAL MODEL REGULATIONS FOR THE
CONTROL OF WORKPLACE HAZARDOUS SUBSTANCES
Pursuant to sub-section 38(4) of the National Occupational Health and Safety Commission
Act 1985 (Commonwealth), the National Occupational Health and Safety Commission
(NOHSC) hereby gives notice that it is proposing to include actinolite, anthophyllite and
tremolite forms of asbestos on Schedule 2, "Substances Prohibited for Specified Uses", of the
National Model Regulations for the Control of Workplace Hazardous Substances. The
proposed entry in Schedule 2 is:

Actinolite, anthophyllite and tremolite forms of asbestos ?all uses except for
- removal and disposal purposes; and
- situations where actinolite, anthophyllite and tremolite occur naturally; and
- are not used for any new application.

In accordance with the requirements of section 38(4) of the National Occupational Health
and Safety Commission Act 1985 (Commonwealth), NOHSC is inviting public comment on
the proposed inclusion of actinolite, anthophyllite and tremolite forms of asbestos on
Schedule 2, "Substances Prohibited for Specified Uses", of the National Model Regulations
for the Control of Workplace Hazardous Substances in order to canvass the widest possible
range of views in the community. When NOHSC has considered public comment, it will
decide on the inclusion of actinolite, anthophyllite and tremolite forms of asbestos on
Schedule 2.

An information package describing the basis of this proposal and a Regulatory Impact
Statement (RIS) is available free of charge by downloading from the NOHSC Website at:
www.nohsc.gov.au/NewsAndWhatsNew/MediaReleases/mr-280602A.htm

Alternatively, if you wish to have a downloaded copy sent to you, place your request by:

? telephone to Freecall 1800 666 843 ?follow the prompts when the call is answered;
or
? fax (02) 6279 1150 ?mark your fax `Proposed Additions to Schedule 2' and include
your name and postal address; or
? email to joanne.cuthbert@nohsc.gov.au ?title your email `Proposed Additions to
Schedule 2' and include your name and postal address.

Public comment closes on 30 August 2002.
