Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The acute dermal toxicity dose (LD50) value was considered to be >2000 mg/kg bw, when rabbits were treated with given test chemical by dermal applcation.
- Executive summary:
The acute dermal toxicity study was conducted by using test chemical in rabbits at the concentration of 2000 mg/kg bw. No mortality was observed at 2000 mg/kg bw. Hence, LD50 value was considered to be >2000 mg/kg bw, when rabbits were treated with given test chemical by dermal application.
