Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on results obtained the test item is not classified as eye irritating
- Executive summary:
Instillation of 0.1 ml of the test item into one eye of each of the animals resulted in effects on the iris in two animals and on the conjunctivae in all three animals. Iridic irritation, grade 1, was observed on day 1 in the two animals and had resolved within 24 hours. The irritation of the conjunctivae consisted of redness and chemosis of the conjunctival tissues and discharge. The irritation had resolved completely within 7 days in two animals and within 14 days after instillation in the third animal. Treatment of the eyes with 2% fluorescein, 24 hours after test substance instillation revealed no corneal epithelial damage in any of the animals. There was no evidence of ocular corrosion. No staining of peri-ocular tissues by the test substance was observed.
The test item was considered as not irritating to the rabbit eye.
