Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- According to OECD 404 test method and Draize Dermal Classification System, the PII for CJ301 in intact skin was 0.11 and CJ301 was categorized as mild irritant based on GHS criteria. However, according to ECHA guidance on the application of the CLP Criteria 3.2.2.3.2.2 in vivo data, for up to 3 rabbits test the Skin Irritant Category 2 is used if at least 2 animals show a mean score of 2.3 or above. Therefore, CJ301 is not classified as irritant based on CLP criteria.
- Executive summary:
This test using the procedures outlined in the QPS Taiwan Study Plan for T65315013-IR which is based on the SOP for the OECD 404 (CTPS-TE00440) and OECD 404 (OECD, 2015). The sites were grades for erythema and edema at 1, 24, 48 and 72 hours after the patches removal. No clinical signs of toxicity were found. Body weight changes were within the normal range in all animals. Erythema with score 1 was observed in one animal during 24 hours after patch removal. The Primary Irritation Index for CJ301 was calculated to be 0.11. On the basis of CJ301 given above and according to Draize Dermal Classification System, the response of the test article was categorized as mild irritant.
