Any other information on results incl. tables

Residual test material was noted around the treated eye of all animals one hour after treatment.

No corneal or irridial effects were noted during the study.

Minimal conjunctival redness was noted in two treated eyes one hour after treatment.

All treated eyes appeared normal after treatment.

The test substance was non-irritating when tested in the eyes of three albino rabbits according to OECD 405 Test Guideline.

Applicant's summary and conclusion

Executive summary:

A study was performed to assess the irritancy potential of the test material to the eye of the New Zealand White rabbit according to OECD TG 405.

A single instillation of the test material to the non-irrigated eye of three rabbits produced incidents of minimal conjunctival redness. All treated eyes appeared normal 24 hours after treatment.

The test material was classified as non-irritant according to CLP classification criteria. No classification is required.
