Amount / concentration applied:

FAT 40069/A was applied to each side in quantities of 0.5 g. Before application a 50 % polyethylene glycol trituration (PEG 400) was made.

Duration of treatment / exposure:

24 hours

Observation period:

72 hours

Number of animals:

6 rabbits (3 males and 3 females)

Details on study design:

Rabbits were shaved on the whole back and flanks two days before treatment with an electric clipper. The shaven skin on the left side was slightly scarified immediately before treatment. A gauze patch 2.5 x 2.5 cm was soaked with the test substance and immediately applied to the prepared skin. The patch was covered with a plastic film 5 x 5 cm, which was fixed to the body with adhesive tape. The gauze patches were removed 2 4 hours after the application. The reaction of the skin was appraised upon removal and 72 hours after it, on the basis of the following evaluation scheme.

Executive summary:

A study was performed to determine the primary-irritation index, which serves as a measure of the acute irritation, provoked by the compound, FAT 40069/A, on the skin of the rabbits according to the "Appraisal of the safety of chemicals in foods, drugs and cosmetics (1959) of the US Association of Food and Drug Official (AFDO). Six rabbits (3 males and 3 females), Russian breed, were shaved on the whole back and flanks two days before treatment with an electric clipper. The shaven skin on the left side was slightly scarified immediately before treatment. A gauze patch 2.5 x 2.5 cm was soaked with the test substance and immediately applied to the prepared skin.

Before application a 50 % polyethylene glycol trituration (PEG 400) was made. The gauze patches were removed 24 hours after the application. The reaction of the skin was appraised upon removal and 72 hours after it. In conclusion, The primary irritation index as the measure of the acute irritation to the skin of rabbits was found to be 0.5. FAT 40069/A is to be considered as a non-irritant to the skin of rabbits.

Interpretation of results:

GHS criteria not met

Conclusions:

FAT 40069/A is to be considered as a non-irritant to the eye of rabbits.

Executive summary:

A study was performed to determine the eye irritation potential of FAT 40069/A on rabbits according to the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the US Association of Food and Drug Officials (AFDO). The substance was tested on 6 rabbits (3 males/3 females) of the Russian breed and only rabbits showing normal ophthalmic findings were included in the test. Amounts of 0.1 g of the test substance were introduced into the conjunctival sac of the left eye with a spatula. After application, the eyelids were held open for a few seconds. The right eye served as a control. The treated eyes of three rabbits were each rinsed with 10 ml lukewarm water about 30 seconds after treatment. The reactions were appraised with a slit-lamp after 24 hours and after 2, 3, 4 and 7 days. The primary-irritation index, which serves as a measure of the acute irritation provoked by the substance, was found to be 10.8 for the cornea, 0 for the iris and 6 .9 for the conjunctivae. The effects were observed to be completely reversible by the end of Day 7. FAT 40069/A is to be considered as a non-irritant to the eye of rabbits.

Additional information

A study was carried out to determine the primary-irritation index, which serves as a measure of the acute irritation, provoked by the compound, FAT 40069/A, on the skin of the rabbits according to the "Appraisal of the safety of chemicals in foods, drugs and cosmetics (1959) of the US Association of Food and Drug Official (AFDO). The primary irritation index as the measure of the acute irritation to the skin of rabbits was found to be 0.5. The effects were observed to be completely reversable by the end of Day 7. FAT 40069/A is to be considered as a non-irritant to the skin of rabbits.

Justification for selection of skin irritation / corrosion endpoint:
Basic data given, acceptable for assessment

Justification for selection of eye irritation endpoint:
Basic data given, acceptable for assessment

Justification for classification or non-classification

Based on the above stated assessment, FAT 40069/A is to be considered as a non-irritant to the skin and eyes of rabbits according to CLP (Regulation (EC) No 1272/2008 of the European Parliament and of the Council.
