- Irritant / corrosive response data:
- Conjunctival redness, grade 2 was the only finding 1 h after treatment in all 3 animals. However, reversibility was evident and conjunctival redness grade 1 was observed in all 3 animals at 24 h post-treatment and in one animal only at 48 h. Ocular effects were completely resolved in all animals at 72 h.
- Other effects:
- There was reduced food intake in 2/3 test animals which was considered to be not test substance related by the investigators.
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 was performed in accordance to OECD TG 405 under GLP conditions and is considered reliable. The test substance was determined to be non-irritating.
