- Details on study design:
- An area of at least 6 cm² was shaved on both flanks of the animals approximately 24 hours before treatment. A gauze patch (20cm²) bearing 0.5g of the test substance was applied to the flank. A control gauze patch was applied to the contralateral flank. Both gauze patches were moistened before application with distilled water.
The patches were loosely covered with an aluminium foil (36 cm²) and held in place for 4 hours by an adhesive tape (Isoplast, Isoplast AG, CH-5200 Brugg).
- The animals were checked daily for systemic symptoms and mortality.
- The skin reactions were evaluated 1, 24, 48, and 72 hours after removing the gauze patches according to the OECD scoring system.
- The body weight was recorded at start and on days 3, 7 and 14 of the test.

- Irritant / corrosive response data:
- No edema formation was observed during an observation period of 14 days.
- Other effects:
- The application area was stained blue (substance-related) up to the end of the observation period. Therefore the evaluation of a possible slight erythema formation was impeded. However, a marked erythema formation was not noted and on the unstained marginal zone of the application area no erythema was recorded.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT 20242/E can be classified as non-irritant in albino rabbits.
- Executive summary:
The test was performed on 3 male rabbits to determine the irritation or corrosive potency of FAT 20242/E. This test was concucted as per OECD Guideline 404.
A gauze patch (20 cm2) bearing 0.5 g of the test substance was applied to shaved area on the flank.
No edema formation was observed during an observation period of 14 days. The application area was stained blue (substance-related) up to the end of the observation period. Therefore the evaluation of a possible slight erythema formation was impeded. However, a marked erythema formation was not noted and on the unstained marginal zone of the application area no erythema was recorded.
Hence it can be concluded that under the experimental conditions, FAT 20242/E did not induce skin irritation when applied to the shaved albino rabbit skin.

- Irritant / corrosive response data:
- Cornea and conjunctiva of the treated eye of animals No. 66 and 67 and the cornea of animal No. 68 were blue-stained (substance-related) one hour after the application of the test compound.
Because of maximal opacity of the cornea in animals No. 66 and 67, the evaluation of possible iris reactions was impeded.
FAT 20242/E induced maximal irritant effects in animals No. 66 and 67 which were expected not be reversible within 21 days. The animals were sacrificed for protective reasons 72 hours after instillation of the test compound. - Other effects:
- None
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- FAT 20242/E is concluded to pose risk of serious damage to eyes.
- Executive summary:
An acute eye irritation/corrosion study was performed to determine the irritant or corrosive potency of FAT 20242/E. This test was conducted based on the OECD Guideline No. 405. The substance was tested undiluted to determine the irritant potency on 3 female rabbit eyes.
0.1 ml of FAT 20242/E was placed into the conjunctival sac of the right eye of each animal, after gently pulling away the lower lid from the eyeball. The lids were then held together for about one second in order to prevent loss of the test material. The left eye remained untreated and served as a control.
Cornea and conjunctiva of the treated eye of animals No. 66 and 67 and the cornea of animal No. 68 were blue-stained (substance-related) one hour after the application of the test compound. Because of maximal opacity of the cornea in animals No. 66 and 67, the evaluation of possible iris reactions was impeded. FAT 20242/E induced maximal irritant effects in animals No. 66 and 67 which were expected not be reversible within 21 days. The animals were sacrificed for animal protective reasons 72 hours after instillation of the test compound. Hence it can be concluded that, under the experimental conditions employed, FAT 20242/E induced strong irritation of the cornea and conjunctiva. The test compound possess the risk of serious damage to the eyes

Additional information
Skin:
A study performed on male rabbits, checked for skin conditions to determine the irritant or corrosive potency of FAT 20242/E on the albino rabbit skin. This test was based on the OECD guideline No. 404. The results showed no edema formation during an observation period of 14 days. However, at the application area blue-stains (substance-related) were observed up to the end of the observation period. Therefore the evaluation of a possible slight erythema formation was impeded. A marked erythema formation was not noted and on the unstained marginal zone of the application area no erythema was recorded. Hence, it was concluded , that under the experimental conditions FAT 20242/E did not induce irritation when applied to the shaved albino rabbit skin.
The supporting study was done according to the "Primary dermal Irritation study", Federal Register, Vol. 43, No. 163, August 22, 1978. New Zealand White rabbits (3 males and 3 females), were used for the experiment. Before treatment the entire back and the flank of the rabbits were shaved with an electric clipper and immediately before treatment the shaven skin on one side was slightly scarified with the help of a "SchröpfSchnäpper", Aesculap, Switzerland. Gauze patches of 2.5 x 2.5 cm laden with 0.5 g of the test material were applied to the prepared abraded and intact skin and exposure lasted for 24 hours. No erythema or edema was seen at the application sites throughout the observation period. In conclusion, the primary irritation index as the measure of the acute irritation to the skin of rabbits was found to be 0. Therefore FAT 20242/A is considered as not irritant to the skin of rabbits.
Eye:
In a study (Key study), based on the OECD guideline No. 405, cornea and conjunctiva of the treated animals were blue-stained (substance-related) one hour after the application of the test compound. Because of maximal opacity of the cornea in animals, the evaluation of possible iris reactions was impeded. FAT 20242/E induced maximal irritant effects in 2 animals which were expected not be reversible within 21 days. The animals were killed for animal welfare reasons 72 hours after instillation of the test compound. On account of the mean value obtained 24 to 72 hours after instillation of the test compound the risk of serious damage to eyes is expected. Based on these findings, it was concluded that FAT 20242/E possess the risk of serious damage to eyes.
Couple of supporting studies carried out in 1980 -1981 and 1987 are available. The test item was found to have minimal irritation to eyes in these studies.
Justification for classification or non-classification
FAT 20242 did not induce skin irritation in animals, however found to be irritating to eyes. Hence it needs to be classified as causing eye damage (cat 1) as per the criteria of Regulation (EC) No. 1272/2008 (CLP).
