Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Executive summary:
0.1 g of Casul-Pulver getrocknet (Ettringit) were applied to the conjunctival sac of one eye of 3 New Zealand White rabbits. After 1 hour the eyes were rinsed with plenty of 0.9 % NaCl-solution. The eye irritation was scored and recorded after 1, 24, 48, 72 hours, 7 days and 14 days after application. According to the classification criteria the test item is not irritating to eyes.
