Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In a reliable skin irritation study conducted in accordance to an appropriate national test guideline similar to OECD Test Guideline 404, the substance was found to be non-irritant to rabbit skin. The test pre-dated GLP.
