Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information
- Conclusions:
- Under the conditions of the performed eye irritation study, the test substance was determined to be not irritating to the eye.
- Executive summary:
The potential to cause damage to the conjunctiva, iris or cornea was assessed in an OECD 405 guideline study in compliance with GLP. Three white Vienna rabbits were subjected to a single ocular application of 0.1 mL of the test substance on day 0. The mean score (24 to 72 hours) for irritation was calculated to be 0 (all animals) for corneal opacity and iris, 0, 0.3, and 0 for chemosis and 1, 1, and 0.7 for conjunctivae redness for animal 1, 2, and 3 respectively. The eye findings observed for chemosis were reversible within 48 hours and the findings for conjunctivae redness 72 hours after instillation. Based on these findings it is concluded that the test substance is not irritating to the eye.
