Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye)
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The substance is a severe eye irritant
- Executive summary:
The test substance was applied to the eye of 6 rabbits. Severe effects on cornea and iris were observed during the 14 day observation period. The effects including those on the conjunctivae were not fully reversible. The substance is considered to be a severe eye irritant and has to be classified as H318.
