Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT 40062/A is to be considered as non-irritant to the eye of rabbits.
- Executive summary:
FAT 40062/A, was evaluated for primary eye irritation after instillation of 0.1 g of the test substance into the conjunctival sac of the left eye of 6 rabbits (3 males/ 3 females) of the Russian breed, which were kept separately in V2A wire mesh cages. After application, the eyelids were held open for a few seconds. The right eye served as a control. Only rabbits showing normal ophthalmic findings were included in the test. The eyes of 3 of these 6 rabbits were rinsed with 10 ml of lukewarm water about 30 seconds after treatment. The treated eyes of all animals (washed and unwashed) were evaluated after 24 h 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 0 for the conjunctivae.
Therefore, FAT 40062/A is to be considered as non-irritant to the eye of rabbits.
