Applicant's summary and conclusion

Interpretation of results:

Category 2 (irritating to eyes) based on GHS criteria

Conclusions:

According to OECD 405 test method, CJ306 showed that positive irritant to the eye and reversible. Therefore, CJ306 was categorized as irritating to eyes (Category 2) base on GHS criteria.

Executive summary:

This test using the procedures outlined in the QPS Taiwan Study Plan for T65315010-IR which is based on the SOP for the OECD 405 (CTPS-TE00441) and OECD 405 (OECD, 2012).There were no test article effects on mortality, clinical observations and body weight.CJ306 was given by a single ocular application at 100 mg amount toNZW male rabbits andfollowed by ocular examination and clinical observation for 14 days. Reversible corneal opacity, hyperemia of iris, and conjunctiva redness and chemosis were observed within 14 days.On the basis of the test results given above, the response of the test article was judged as a positive irritant to the eye.
