Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

FAT 36014/F is not irritating to the eye.

Executive summary:

A study was conducted to assess the eye irritancy potential of the FAT 36014/F (of purity 90.7 %) in New Zealand White rabbits according to OECD Guideline 405 and EU Method B.5 in compliance with GLP. A single ocular dose of 87±1 mg of test substance was applied into the lower eye lid of one eye of each animal. The eyelids were then gently held together for one second before releasing. The untreated eye served as control. Without washing, eyes were scored for irritation reactions at 1, 24, 48, and 72 h and 7 d post-instillation. Slight conjunctival irritation was observed, which resolved within 7 d of instillation. Ocular corrosion was not observed in any of the rabbits. Also, no signs of systemic intoxication were seen. Hence, it can be concluded that the test substance is not to be classified as irritating to the eye.
