- Irritant / corrosive response data:
- Slight corneal opacity (grade 1) was observed in all animals 24 and 48 hours after application and persisted in two animals until the 72 hour reading. Moderate iritis (grade 1) was observed in all animals 24 hours after application and in one animal again after 72 hours. Moderate conjunctival redness (grade 2) was noted in all animals from 1 hour up to 72 hours after application. Moderate or marked conjunctival chemosis (grade 2 or 3) was noted in all animals 1 hour after application. Slight or moderate conjunctival chemosis (grade 1 or 2) was observed in all animals at the 24- and 48-hour reading. Slight conjunctival chemosis was seen in two animals after 72 hours. Slight to severe discharge (grade 1 to 3) was noted in all animals from 1 hour up to 24 hours. Moderate discharge (grade 2) was observed in a single animal after 48 hours. Slight discharge was noted in two animals after 72 hours.
Additional findings like contracted pupil and injected scleral vessels in a circumscribed area or circular were noted in all animals during the observation period.
The ocular reactions were reversible in all animals within 7 days after application.

Applicant's summary and conclusion
- Interpretation of results:
- Category 2B (mildly irritating to eyes) based on GHS criteria
- Conclusions:
- Considering the described ocular reactions as well as the average score for irritation, the test substance shows a slight eye irritation potential under the test conditions chosen.
- Executive summary:
The potential of the test substance to cause damage to the conjunctiva, iris or cornea was assessed by a single ocular application of 0.1 mL bulk volume (about 31 mg) of the test substance to one eye of three New Zealand rabbits (stepwise procedure starting with one animal and supplementing two additional animals). About 24 hours after application the eye was rinsed with tap water.
The ocular reactions were assessed approximately 1, 24, 48 and 72 hours after application and on day 7.
Slight corneal opacity, moderate iritis, moderate conjunctival redness, slight to marked conjunctival chemosis and slight to severe discharge were observed in the animals during the course of the study.
Additional findings like contracted pupil and injected scleral vessels in a circumscribed area or circular were noted in the animals during the observation period.
The ocular reactions were reversible in all animals within 7 days after application.
Mean scores calculated for each animal over 24, 48 and 72 hours were 0.9 for corneal opacity, 0.4 for iris lesions, 2.0 for redness of the conjunctiva and 1.2 for chemosis.
Considering the described ocular reactions as well as the average score for irritation, the test substance shows a slight eye irritation potential under the test conditions chosen.
