Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Considering the described ocular reactions as well as the average score for irritation, the test article does not show an eye irritation potential under the test conditions chosen.
- Executive summary:
The test article's potential to cause damage to the conjunctiva, iris or cornea was assessed by a single ocular application of 0.1 mL bulk volume (about 16 mg) of the test substance to one eye of three White New Zealand rabbits (stepwise procedure starting with one animal and supplementing two additional animals). The study was performed according to OECD test guideline 405 and in compliance with GLP. About 1 hour after application the eye was rinsed with tap water. The ocular reactions were assessed approximately 1, 24, 48 and 72 hours after application. Slight to moderate conjunctival redness, slight conjunctival chemosis and slight discharge were observed in the animals up to 24 hours after application. Two animals showed injected scleral vessels in a circumscribed area. The ocular reactions were reversible in all animals within 48 hours after application. The average score (24 to 72 hours) for irritation was calculated to be 0.0 for corneal opacity, iris and chemosis and 0.3 for conjunctival redness. In conclusion, considering the described ocular reactions as well as the average score for irritation, the test article is considered to be not irritating under the test conditions chosen.
