- Irritant / corrosive response data:
- There was no corneal opacity observed in any treated eye during the study. Iritis (score of 1), conjunctival redness (score of 1 or 2), conjunctival chemosis (score of 1), and discharge (score of 1 or 2) were observed in the treated eye of all three rabbits. All animals were free from ocular irritation by 72 hours.
- Other effects:
- All animals appeared active and healthy during the study. No biologically significant weight loss occurred in any of the rabbits. Apart from the eye irritation, there were no other signs of gross toxicity, adverse pharmacologic effects, or abnormal behaviour.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- The study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability).
There was no corneal opacity observed in any treated eye during the study. Iritis (score of 1), conjunctival redness (score of 1 or 2), conjunctival chemosis (score of 1), and discharge (score of 1 or 2) were observed in the treated eye of all three rabbits. All animals were free from ocular irritation by 72 hours. - Executive summary:
The test substance was evaluated for acute eye irritation potential in 3 young adult New Zealand White rabbits. There was no corneal opacity observed in any treated eye during the study. Iritis (score of 1), conjunctival redness (score of 1 or 2), conjunctival chemosis (score of 1), and discharge (score of 1 or 2) were observed in the treated eye of all three rabbits. All animals were free from ocular irritation by 72 hours.
