Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
According to OECD 405 test method, CJ308 showed that positive irritant to the eye. Therefore, CJ308 was not met a category based on GHS criteria.
Executive summary:

This test using the procedures outlined in the QPS Taiwan Study Plan for T65316005-IR which is based on the SOP for the OECD 405 (CTPS-TE00441) and OECD 405 (OECD, 2012). CJ308 was given by a single ocular application at 0.1 g amount to NZW female rabbits and followed by ocular examination and clinical observation no more than 21 days. There were no test article effects on body weight. Reversible conjunctivalredness and chemosiswas observed within 7 days after test article application. On the basis of the test results given above, the response of the test article was judged as a light irritant to the eye.

However, the result has not met a category based on GHS criteria.
