Comments on Physico-Chemical Properties
The boiling point of the notified chemical was not determined. However, the formulation
containing the notified chemical, Dehyquart AU 56, has a boiling point of greater than 150癈
and a melting point of 37-42癈.
The vapour pressure of the notified chemical was not determined. The notifier indicates that
the chemical is an organic salt with a relatively high molecular weight. Therefore, it is
expected to be relatively non-volatile.
The water solubility of the notified chemical was not determined. The notifier indicates that
the chemical has surfactant type properties and that measurement of water solubility would
be difficult. It is noted from the ecotoxicity studies of Esterquat C16-C18 (an analogue of the
notified chemical) on fish, water flea and algae indicate that the notified chemical would not
be readily soluble and solutions of greater than 120 mg/L are cloudy (Section 10).
C16-C18 Esterquat is derived from palm oil, which mostly contains saturated fatty acids.
Hydrolysis of the notified chemical was not determined. The notifier indicates that the pH of
a 5% solution of the notified chemical is 2 to 3 and that the stability of the notified chemical
below pH 5 is practically constant. The notified chemical contains ester linkages that could
be expected to undergo hydrolysis under extreme pH. The notifier confirms this by
indicating that the main degradation intermediate from the notified chemical does not contain
ester groups.
FULL PUBLIC REPORT 1 November, 2000
NA/748 Page 3 of 29
The partition coefficient log POW of the notified chemical between n-octanol and water was
not determined. The notifier indicates that the notified chemical has surfactant type
properties and that measurement of partition coefficient would not be meaningful.
The adsorption/desorption coefficient of the notified polymer was not determined. The
notifier indicates that the notified chemical is expected to undergo anion-exchange in the
environment and adsorb strongly to both silicates and organic matter
The dissociation constant of the notified chemical was not determined. The notifier indicates
that the notified chemical is expected to dissociate completely in water. In contrast this
assessment finds that the notified chemical is poorly soluble in water, less than 120 mg/L and
that above this concentration, it would be expected to aggregate and form a dispersive
solution, then precipitate. Furthermore, some of the components of the notified chemical
mixture are not quaternized and as free esters would be expected to have lower water
solubility. However, any free amine in solution could become protonated. This process may
only occur slowly due to steric hinderance.

5. USE, VOLUME AND FORMULATION
The notified chemical is to be used as a textile softener in the industrial processing of cotton
and cotton blends.
The notified chemical will not be manufactured in Australia. It will be imported by sea in
either 800 kg bulk containers or 200 L drums as Megasoft JET which contains 2% of the
notified chemical. No repackaging of Megasoft JET will occur and the original import
FULL PUBLIC REPORT 1 November, 2000
NA/748 Page 5 of 29
containers will be transported by road and stored at the notifiers warehouse prior to dispatch
to the customer site. Estimated import volumes for Megasoft JET are two tonnes (40 kg of
the notified chemical) for the first year increasing to four tonnes (80 kg of the notified
chemical) in years two to five.
At the customer site, Megasoft JET is mixed with water in a ratio of 1:4 up to 1:20. The
diluted chemical is then applied to cotton and cotton blend textiles by the exhaust method.
The extent of exhaustion of notified chemical to textile fibre is 95%.
6. OCCUPATIONAL EXPOSURE
Transport and Storage
Megasoft JET, containing the notified chemical is to be imported in 800 kg bulk containers or
200L drums. Exposure of waterside, transport and storage workers should only occur in the
event of accidental spillage.
Dye House
The notifiers estimate eight customer sites where Megasoft JET will be used and the
following number and category of workers per site with potential exposure to the notified
chemical:
Weighing/Dispersing: 2 operators per shift;
Application: 6 operators per shift;
Drying: 4 operators per shift; and
Laboratory: 2 technicians.
Megasoft JET is dispensed manually from the import containers into a bucket for weighing.
The volume weighed depends upon the batch size; at an application rate of 2%, this varies
from 0.5kg to 16 kg of Megasoft JET. The weighed Megasoft JET is then diluted with water
in an open tank at a ratio of 1:4 to 1:20 (0.4 to 0.1% notified chemical), then pumped into a
closed dyeing machine. After completion of the dyeing process, the wet cloth is winched
from the machine and spun to remove excess moisture (hydroextraction). It is then dried by
passing through a stenter.
The notifiers identified that skin and eye and contact to Megasoft JET can occur at:
preparation of the dye stuff (weighing; dilution; addition to the dyeing machine); during
dyeing (de-tangling of cloth in the dye machine) and drying (looping wet cloth onto the
winch and stenter). The notifier indicated that inhalation exposure to mists or vapours would
only exist in the event that aerosol was generated by spraying, or during work in confined
spaces or poorly ventilated areas. Engineering controls in use as identified by the notifier,
include local exhaust ventilation at the weigh station and dilution vessel. For all operations,
existing hygiene practices require the wearing of overalls, protective gloves (PVC, long
impervious) and goggles or safety glasses. In the event that inhalation exposure may occur,
the notifier recommends the wearing of half face respirators (class A-2 Organic Vapour
Cartridge).
Information on the role of the laboratory technicians was not provided in the submission.
However, typical duties would involve sampling of the dye for quality control (QC) and
FULL PUBLIC REPORT 1 November, 2000
NA/748 Page 6 of 29
potential for skin and eye contact exists. It is expected that technicians would be wearing
safety glasses and gloves during these activities.
7. PUBLIC EXPOSURE
It is expected that during transport, storage, processing and disposal, exposure of the general
public to the notified chemical will be very low. The public will be exposed to the notified
chemical in cotton textile products. However, the majority (95%) of the notified chemical
will be firmly fixed to the cotton textile fibres rendering the chemical biologically
unavailable.
8. ENVIRONMENTAL EXPOSURE
Release
The notified chemical will be transported by road in the original import containers; potential
release would only be through accidental spills. The Material Safety Data Sheet (MSDS)
details adequate procedures to protect the environment in these cases.
The notifier indicates that release of the notified chemical during formulation via mixing
vessels, holding vessels, filling pots, filling lines and empty drums is not expected to be of a
significant quantity. The submitted data shows that the notified chemical exhausts onto the
fibre of cotton to about 95%. The unfixed 5% pass through the exhausting process as trade
waste. The notified chemical constitutes 2% of the 5% quantity released. If a maximum of
100 kg of Megasoft JET were used in a day for 5 tonne of textile, the release of unfixed
notified chemical would be 100 g. With a maximum import of 4 tonnes per year then
approximately 4 kg of the notified chemical maybe lost per year. The notifier also estimates
that the amount lost from washing of equipment and drums will be one kg per 800 kg
container. This is equivalent to a loss of 100 g of the notified chemical per year.
The majority of the notified chemical will be fixed to cotton textiles.
Fate
Any small quantities of notified chemical waste at the formulation and processing site that
maybe generated from spills and drum washings will be collected together with production
effluents through the site waste water treatment plant. The notifier indicates that this will
then be released to sewer according to local waste water specifications.
The ready biodegradability of Dehyquart AU 56 was examined by exposure to activated
sewage sludge microorganisms in a closed bottle test, OECD TG 301D (Henkel KGaA,
1998). A very brief report was submitted for assessment. Under the conditions of the test 87
to 88% of the test substance was degraded within the 28 day test period. Since the pass level
of 60% was reached within the 10 day time window, Dehyquart AU 56 can be regarded as
readily biodegradable.
The anaerobic biodegradability of the palm oil derived C16-C18 Esterquat analogue was also
examined by exposure to activated sewage sludge microorganisms in an ECETOC screening
FULL PUBLIC REPORT 1 November, 2000
NA/748 Page 7 of 29
test (Birch et al, 1989), (Henkel KGaA, 1994d). The notifier indicates that this anaerobic
biodegradation test is monitored by means of weekly measurements of biogas formation and,
at the conclusion of the test by the carbon dioxide formed and that remaining in solution as
dissolved inorganic carbon. In the screening test, 71% of the test substance was degraded
within the 77 day test period. C16-C18 Esterquat can be regarded as readily degradable
under the anaerobic test conditions.
The aerobic biodegradability of C16-C18 Esterquat was also examined by exposure to
activated sewage sludge microorganisms in a BODIS screening test (a modified OECD TG
301 D closed bottle test for insoluble substances) (Henkel KGaA, 1994e). Under the
screening conditions 79% of the test substance was degraded within the 28 day test period.
Since the pass level of 60% was reached within the 14 day time window, C16-C18 Esterquat
can be regarded as readily biodegradable.
The ultimate fate of the bulk of the notified chemical will be associated with the cotton
textiles to which it is applied. The fate will be to landfill, in a very diffuse manner, and in
locations country wide where it is expected to readily biodegrade.
The notified chemical shows considerable potential for biotic transformation. It is readily
biodegradable as well as slightly unstable in aqueous solution and as such should not
bioaccumulate.
9. EVALUATION OF TOXICOLOGICAL DATA
A skin irritation study in rabbits has been conducted on the notified chemical.
In support of a claim for Variation to the Schedule Requirements study reports on analogue
substances, Stepantex VS 90, C16-C18 Esterquat, and Dehyquart F75, covering the following
toxicological end points have been submitted:
Stepantex VS 90:
Eye Irritation;
Skin sensitisation: Buehler Method; Maximisation Method;
Repeat dose toxicity; 90-day, oral; and
Genotoxicity: mouse micronucleus test; bacterial reverse mutation assay
Stepantex VS 90, a close homologue to Dehyquart AU 56, is a quaternised fatty acid ester
and shares the same types of fatty acid, solvent, and solvent-to-chemical ratio as the notified
chemical.
C16-C18 Esterquat:
Acute Toxicity - oral;
Skin Irritation ?human open epidermal test
Genotoxicity ?bacterial reverse mutation assay
C16-C18 Esterquat differs to the notified chemical in that it contains only saturated fatty acid
chains.

Minimal irritating A preliminary study showed the minimal irritating
concentration: concentration (Grade 1 or less) for intradermal induction was
0.5% w/w and for topical induction, 2% w/w.
Induction procedure: test animals:
Day 1: three pairs of intradermal injections (0.1 mL) into the
dorsal skin of the scapular region:
- Freund's complete adjuvant (FCA) 50% v/v in liquid
paraffin;
- the test substance, 0.5%;
- the test substance 0.5% w/v FCA 50% v/v;

dressing for 48 hours;
control animals:
treated similarly to the test animals omitting the test
substance and using the vehicle control, liquid paraffin, for
the intradermal injections and topical application
Comment: Following intradermal and topical induction, no reaction,
Grade 1 or Grade 2 dermal reactions were observed in both
test and control animals.

would be masked under these conditions. Therefore, no
conclusion can be drawn on the sensitisation potential of the
test substance in this study.

9.2 13 Week Repeated Dose Toxicity (Henkel KGaA, 1991a)
Test substance: Stepantex VS 90
Species/strain: Rat/Sprague Dawley CD
Number/sex of animals: 10/sex/group for treatment phase;
5/sex/group for recovery phase (control and high dose
animals).
Method of administration: gavage
Dose/Study duration: 0, 100, 300, 1 000 mg/kg/day for 13 weeks.
Recovery animals were maintained for a further 35 days
without treatment.
Test method: OECD TG 407
Mortality:
One male of the 1 000 mg/kg/day group was found dead at Week 12. Two males (1 of the
control group, the other of the 300 mg/kg/day group) died under anaesthesia during blood
sampling.
Clinical observations:
The male that died suffered weight loss (37g within 3 days) from Week 11.
No other remarkable findings.
Clinical Pathology
Clinical Chemistry:
Week 6 - animals at 1 000 mg/kg/day had significantly increased alanine transferase (ALT)
activity and males in addition had increased calcium.
Week 13 - the increased ALT persisted. Significant findings in females were increased
alkaline phosphatase (AP) and cholesterol at 1 000 mg/kg/day, and increased creatinine at
100 and 1 000 mg/kg/day. In males, significantly increased potassium at 300 and 1 000
mg/kg/day. Clinical chemistry investigations of recovery animals were not conducted.
Haematology:
Increased platelet counts were observed at Week 6 in males at 300 mg/kg/day. At Week 13
females at 1 000 mg/kg/day had slightly decreased mean cell volume. Haematology
investigations of recovery animals were not conducted.
Histopathology:
Treatment phase:
An underlying bacterial infection was present in all animals, manifested by the presence of
non dose related histological changes in the liver and salivary gland lymph nodes;
At 1 000 mg/kg/day, the bladder showed increased desquamation, localised regressive
changes in the epithelium to focal epithelium denudation without inflammatory reaction in

NA/748 Page 16 of 29
the submucous area. These findings predominated in males and were suggested as been
due to local irritation as no corresponding changes were observed in the kidney, renal
pelvis, or urethra;
The omasum at 1 000 mg/kg/day showed thickening of the mucous membrane,
inflammatory infiltration in the sub mucosa and isolated ulceration, these changes were
considered a local irritation response.
Recovery phase:
Changes to the bladder and omasum were not observed in recovery animals.
Comment:
At 1 000 mg/kg/day, effects related to treatment were observed in the liver (elevated ALT)
and effects secondary to treatment (local irritation) were observed in the bladder and
omasum. No systemic effects were observed at 300 mg/kg/day.
Result:
The No Observed Adverse Effect Level (NOAEL) determined for Stepantex VS 90 in this
study is 300 mg/kg/day.

9.4 Overall Assessment of Toxicological Data
Variations to the Schedule Requirement were claimed by the notifier, with submission of
data on analogue substances, Stepantex VS 90, Esterquat C16-C18 and Dehyquart F75.
FULL PUBLIC REPORT 1 November, 2000
NA/748 Page 19 of 29
The notified chemical is not expected to cause acute systemic toxicity based on the results of
an oral toxicity test with the analogue Esterquat C16-C18. In addition, quaternized fatty acid
esters, such as the notified chemical, are generally considered to be of low dermal toxicity.
The notified chemical was a slight to moderate skin irritant in rabbits and is expected to have
similar slight to moderate eye irritant properties as observed with Stepantex VS 90 when
tested in rabbits. Esterquat C16-C18 was non irritating to human skin following repeat
application.
Stepantex VS 90 is considered non sensitising to guinea pig skin in a non-adjuvant study.
The results of an adjuvant study using Stepantex VS 90 are confounded by the presence of
moderate or strong erythema and/or oedema observed in the majority of control animals at
challenge. Therefore, no conclusion can be reached on the skin sensitisation potential of the
analogue under the conditions of the test. Signs of skin sensitisation were not observed in a
human repeat insult patch test with Dehyquart F75. Based on these findings with analogue
substances, the notified chemical is not expected to display skin sensitisation potential.
In a 90 day repeat oral dose study in rats administered Stepantex VS 90, a NOAEL of 300
mg/kg/day was established. At 1 000 mg/kg/day, effects related to treatment were observed
in the liver (elevated ALT) and effects secondary to treatment (local irritation) were observed
in the bladder and omasum.
In a bacterial reverse mutation test, with and without metabolic activation, Esterquat C16-
C18 and Stepantex VS 90 were both considered non mutagenic. Stepantex VS 90 was non
genotoxic in vivo, in a micronucleus assay. Based on the results of the analogue substances,
the notified chemical and its metabolites are also expected to be non genotoxic.
The notified chemical would likely display the same toxicity profile to the analogue
substances of similar chemical composition and would be considered non hazardous under
the NOHSC Approved Criteria for Classifying Hazardous Substances Classifying Hazardous
Substances (NOHSC, 1999a).

10. ASSESSMENT OF ENVIRONMENTAL EFFECTS
The notifier has supplied ecotoxicity studies of the notified chemical analogues,
C16-C18 Esterquart and Stepantex VS 90, which are summarised in the following tables.
Stepantex VS 90 is derived from tallow and like C16-C18 Esterquart is a very similar
analogue to the notified chemical. Only concise one-page ecotoxicity reports for Stepantex
VS 90 were submitted.
The tests were performed in compliance with OECD/EEC Test Methods and according to
OECD Principles of Good Laboratory Practices.
10.1.1 C16-C18 Esterquat
Summary of C16-C18 Esterquat Ecotoxicity Test Results

(Static Test) 96 h NOEC = 4.8
(DIN 38412)
10.1.2 Fish Acute Toxicity (Henkel KGaA, 1994a)
Zebra Barbels were exposed to C16-C18 Esterquat in a range finding test at nominal loading
rates of 30, 60, 120 and 240 mg/L for a period of 96 hours under semi-static test conditions.
Zebra Barbels were then exposed to C16-C18 Esterquat at nominal loading rates of 1.0, 2.2,
4.8, 11, 23 and 52 mg/L for a period of 96 hours under semi-static test conditions. Based on
the findings from both studies the 96 hour LC50 was calculated by the notifier to be 42 mg/L.
However, the calculation used by the notifier appears to not follow the Stephan method as
claimed. Furthermore, the Probit method of calculation cannot be used in this case since
there is only one concentration level used between the zero and 100% mortality levels.
Therefore, the 96 hour LC50 can only be stated as being between 30 mg/L and
60 mg/L. The no observed effect concentration (NOEC) was the 30 mg/L nominal rate. Sub-

lethal effects of exposure were not observed. Chemical analyses were also carried out on test
samples with the Total Organic Carbon (TOC) measured at greater than 80% of nominal
concentrations. Test fish were also transferred into fresh test media every 24 hours.
10.1.3 Aquatic Invertebrate Acute Toxicity (Henkel KGaA, 1995)
Daphnia magna were exposed to C16-C18 Esterquat at nominal loading rates of 1, 2, 4, 8,
16, 32, 64, 128 and 256 mg/L for a period of 48 hours under static test conditions. Based on
these nominal loading rates the 48 hour LC50 was calculated by the notifier to be 45 mg/L.
As indicated above the 96 hour LC50 can only be stated as being between 32 mg/L and 64
mg/L. The NOEC was the 32 mg/L nominal rate. Chemical analyses were also carried out
on test samples with similar results to those above. The test media was not changed during
the period of the study.
10.1.4 Alga Growth Inhibition Test (Henkel KGaA, 1994c)
After 96 hours exposure of C16-C18 Esterquat to green alga Scenedesmus subspicatus at
nominal loading rates of 1, 2.2, 4.8, 11 and 23 mg/L, the E礐50 was 44 mg/L and the EbC50
was 11 mg/L. The NOEC at 96 hours was determined to be 4.8 mg/L. Chemical analysis
was not carried out to determine measured concentrations.
10.1.5 Conclusion
The ecotoxicity data for the C16-C18 Esterquat analogue of the notified substance suggests
that it is slightly toxic to fish, aquatic invertebrates and slightly to moderately toxic to alga.

The results above indicate that Stepantex VS 90 appears more toxic to fish and algae and less
toxic to daphnia than is C16-C18 Esterquart. The notifier also supplied concise one-page
ecotoxicity reports on bacteria, plants and earthworms as well as those derived in more
complex systems, that are not listed here.
10.2.1 Microorganisms
The notifier did not study the effect of the notified chemical on the respiration of activated
sewage sludge microorganisms. However, from ready biodegradation data the notified
chemical appears to have no effect on activated sewage sludge microorganisms.
Furthermore, a respiration inhibition study was carried out on Stepantex VS 90 under
standard method DIN 38412/27 1990 which the notifier indicates corresponds to OECD TG
209. Stepantex VS 90 is a close analog to the notified chemical. The study indicated a first
observed effect concentration of 90 mg/L of active substance.
FULL PUBLIC REPORT 1 November, 2000

10.6 Conclusion
The ecotoxicity data for the analogue suggests that it is unlikely to affect sewage
microorganisms.
11. ASSESSMENT OF ENVIRONMENTAL HAZARD
The intended use pattern of the notified chemical is not expected to result in a significant
release to the environment. During a typical formulation and processing application to
5 tonne of cotton, approximately 110 g of notified chemical may be released to the sewer. If
the assessment assumes that the dilution at Metropolitan and Regional waste water treatment
plants is 100 and 1 ML per day, respectively, then the predicted effluent environmental
concentrations will be 1.1 and 110 礸/L, respectively. In relation to the most sensitive
aquatic organism, algae with an estimated EbC50 of 2.0 mg/L for the analogue Stepantex VS
90, environmental safety factors will be 2 000 and 20, respectively. While narrow, the safety
factors are likely to be much greater, if dilution into receiving waters, biodegradation and
potential adsorption in the sewer are taken into consideration.
In the event of spills and minor releases during transfer operations, satisfactory information
on procedures to reduce release to the environment can be found in the MSDS for the
chemical.
Given the above, environmental exposure and the overall environmental hazard is expected to
be low.
12. ASSESSMENT OF PUBLIC AND OCCUPATIONAL HEALTH AND SAFETY
EFFECTS
Toxicological data on the analogue substances, Stepantex VS 90, Esterquat C16-C18 and
Dehyquart F75 indicate the acute oral and dermal toxicity of the notified chemical is expected
to be low. The notified chemical was a slight to moderate skin irritant in rabbits, and is
expected to be a slight to moderate eye irritant. Based on the results of a non-adjuvant study
in guineapigs, and a human repeat patch insult test with analogue substances, the notified
chemical is not expected to display skin sensitisation potential. In a 90-day using Stepantex
VS 90 in rats, a NOAEL of 300 mg/kg/day was established, based on increased serum alanine
transferase activity and microscopic changes suggestive of stomach and bladder irritation at
the next (highest) dose. The notified chemical is not expected to be genotoxic.
Based on the data provided the notified chemical would not be determined to be a hazardous
according to NOHSC Approved Criteria for Classifying Hazardous Substances (NOHSC,
1999a).
The notifier has classified Dehyquart AU 56, containing the notified chemical as a hazardous
substance, Irritant (Xi) R36/38 ?Irritating to Eyes and Skin, based on its isopropanol content
(10%).
FULL PUBLIC REPORT 1 November, 2000

Occupational Health and Safety
Transport and Storage
The notified chemical in Dehyquart AU 56 will be imported at 2% in a formulated product
known as Megasoft JET. Waterside, transport and storage workers should only be exposed to
Megasoft JET in the event of accidental spillage. Exposure after a spill would be controlled
by use of the recommended practices for spillage clean up given in the MSDS supplied by the
notifier.
Dye House
The chemical is used as a textile softener in the cloth dyeing process. The main groups of
workers likely to be exposed to Megasoft JET on a regular basis are those involved in
chemical weighing and those handling the treated fabric after the exhaust process is
completed when the cloth is lead to wash off baths. The chemical is weighed out manually
and weighers are stated to wear long PVC gloves, safety glasses, and overalls. Workers
handling the wet cloth will also need to use personal protective equipment although at this
time 5% of the added chemical remains unfixed and the concentration of notified chemical in
the treatment solution is 0.1 to 0.4%. After washing the fabric, the risk of adverse health
effects to dyehouse workers handling the fabric should be negligible.
Public Health
Megasoft JET will not be sold directly to the public, but will be formulated and applied to
cotton at factories. Once applied to cotton textile, the notified chemical is strongly fixed to
the fibre. Given the low toxicity of the notified chemical and the low concentration in the
treatment mixture (<0.4%), the potential for public exposure to the notified chemical during
all phases of its life cycle, is considered to be low. Based on the above, it is considered that
Dehyquart AU 56 will not pose a significant hazard to public health when used in the
proposed manner.
13. RECOMMENDATIONS
To minimise occupational exposure to Megasoft JET containing the notified chemical the
following guidelines and precautions should be observed:
Safety goggles should be selected and fitted in accordance with Australian Standard
?br>
(AS) 1336 (Standards Australia, 1994) to comply with Australian/New Zealand
Standard (AS/NZS) 1337 (Standards Australia/Standards New Zealand, 1992);
Industrial clothing should conform to the specifications detailed in AS 2919
?br>
(Standards Australia, 1987) and AS 3765.1 (Standards Australia, 1990);
Impermeable gloves should conform to AS/NZS 2161.2 (Standards Australia, 1998);
?br>
All occupational footwear should conform to AS/NZS 2210 (Standards
?br>
Australia/Standards New Zealand, 1994);
Spillage of the notified chemical should be avoided. Spillages should be cleaned up
?br>
promptly with absorbents which should be put into containers for disposal;
FULL PUBLIC REPORT 1 November, 2000
NA/748 Page 25 of 29
Good personal hygiene should be practised to minimise the potential for ingestion;
?br>
A copy of the MSDS should be easily accessible to employees.
?br>
If the conditions of use are varied from its use as a softener in the industrial processing of
cotton and cotton blends, then greater exposure of the public may occur.
