Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The acute Dermal LD50 value was considered to be >3000 mg/kg bw, when rats were treated with test chemical by dermal application to the skin.
- Executive summary:
Acute Dermal toxicity study of test chemical was conducted in rats at the concentration of 3000 mg/kg bw. No mortality was observed in treated rats at 3000 mg/kg bw. Therefore, LD50 was considered to be >3000 mg/kg bw, when rats were treated with test chemical by dermal application to the skin.
