- Irritant / corrosive response data:
- The cornea and the iris were not affected in any animal at any examination term. Slight conjunctival redness (grade 1) was noted in one animal only 1 hour after application, in one animal 1 and 24 hours after application. In the third animal no conjunctival redness was observed.
Slight conjunctival chemosis was noted in all three animals only 1 hour after application. Slight discharge (grade 1) was noted in two animals only 1 h our after application.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Considering the described ocular reactions as well as the average score for irritation, ASA is not irritating to eyes under the test conditions chosen.
