Applicant's summary and conclusion
- Interpretation of results:
- other: not corrosive
- Conclusions:
- In this in vitro eye irritation study in the Isolated Chicken Eyes model, 30 μL of test material were applied to the chicken eyes for 10 sec. After 30, 75, 120, 180 and 240 minutes after the post-treatment rinse the eyes were observed regarding cornea opacity and cornea thickness. Fluorescein retention was measured at time point 0 and 30 min after the post-treatment rinse. Under the conditions of the test, the test material was shown to have no corrosive potential in the Isolated chicken eye (ICE) test prediction model. The result does not allow for the non-classification or classification as irritant of the test substance according to EU classification criteria and therefore further evaluation and/or data generation is required.
