Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritant) based on GHS criteria
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- A reliable study conducted broadly in accordance with OECD 404 and GLP, found the test material to be slightly irritating to the skin of rabbits. According to EU criteria, classification as a skin irritant is required since the observed effects were not reversed at the end of the study.
