Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
FAT 40284/A can be classified as non - irritant to the eyes.
Executive summary:

An acute eye irritation/corrosion study in albino rabbits was performed to determine the irritant or corrosive potency of FAT 40284/A on the albino rabbit eye and the associated mucous membranes. This test was based on the OECD guideline No. 405. The test was performed on 3 male rabbits. 0.1 ml (54 mg) of FAT 40284/A 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. The animals were checked daily for systemic symptoms and mortality. The ocular reactions were evaluated 1, 24, 48, and 72 hours after the instillation of FAT 40284/A according to the OECD scoring system. FAT 40284/A induced irritation of the cornea and conjunctiva when applied into the conjunctival sac of albino rabbits. Because the mean values of the readings 24 to 72 hours after application are below the threshold of significance, FAT 40284/A can be classified as non - irritant.
