Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- According to OECD 405 test method, Everzol SB26 showed that no irritant to the eye. Therefore, Everzol SB26 was not met a category based on GHS criteria.
- Executive summary:
This test using the procedures outlined in the SuperLab Study Plan for M62-151100140001EN which is based on the SOP for the OECD 405 (SOPP-306) and OECD 405 (OECD, 2012). There were no test article effects on body weight. Everzol SB26 was given by a single ocular application at 0.1 g amount to NZW female rabbits and followed by ocular examination within 72 hours and a 4 days clinical observation period. Cornea,conjunctivaeand iris with score 0 during all study period. On the basis of the test results given above, the response of the test article was not any irritant to the eye.
