Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
According to OECD 405 test method, CR SB87 showed that weak irritant to the eye. Therefore, CR SB87 was not met a category based on GHS criteria.
Executive summary:

This test using the procedures outlined in the SuperLab Study Plan for M62-151100126001EN which is based on the SOP for the OECD 405 (SOPP-306) and OECD 405 (OECD, 2012). CR SB87 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. There were no test article effects on body weight. Reversible conjunctival chemosis and discharge was observed within 72 hours after test article application. On the basis of the test results given above, the response of the test article was weak irritant to the eye.
