- Irritant / corrosive response data:
- Very slight erythema (grade 1) were noted for all three animals 1 h after exposure. This effect was unchanged at later time points and full reversibility observed within 48 h (1/3 animals) or 72 h (2/3 animals). No effect on edema was observed in all three animals.
- Other effects:
- No further effects were reported.
Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No 1272/2008
- Conclusions:
- The study is in accordance with OECD TG 404, was conducted under GLP and is considered valid and reliable. Under the conditions chosen the test substance did not induce skin irritation to rabbits. According to criteria of the CLP Regulation (EU) No. 1272/2008, no classification of the test item for skin irritation is required.
