Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
FAT 40065/A is considered to be not an eye irritant.
Executive summary:

FAT 40065/A was subjected to eye irritation test. The procedure adopted was the technique described in 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, which were kept separately in V2A wire mesh cages and fed on NAFAG, Gossau SG, rabbit food and water ad libitum. 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 on the basis of the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the AFDO.

The primary-irritation index, which serves as a measure of the acute irritation provoked by the substance, was found to be 0 for the cornea, 0 for the iris and 2.5 for the conjunctivae. Therefore FAT 40065/A is to be considered as a minimal irritant to the eye of rabbits. However the scoring does not meet the threshold scores for classification as proposed by Regulation EC No. 1272/2008. Hence, FAT 40065/A is considered to be not an eye irritant.
