Irritant / corrosive response data:
Cornea and iris were normal.
Conjunctiva redness and swelling appeared after 60 minutes. Swelling disappeared in part in 2 animals after 24 hours and in all after 7 days. Redness disappeared completely after 24 hours.
For individual animal responses, please refer to Table 1 under "any other information on results incl. tables."

Applicant's summary and conclusion

Interpretation of results:
other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No. 1272/2008.
Conclusions:
In the present in vivo eye irritation study in rabbits, the test substance produced weak irritation symptoms in the conjunctiva of the tested animals. The reactions were fully reversible within 7 days. Based on the obtained scores which were below the cut-off values for a positive response, the test substance was concluded not to be irritant to the eye.
