Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The acute dermal LD50 value was considered to be >4000 mg/kg bw, when rabbits were treated with test chemical via dermal application.
- Executive summary:
Acute dermal toxicity study of test chemical was conducted on rabbits at the dose concentration of >4000 mg/kg bw. The test chemical was administered dermally. All animals were maintained under close observation for recording toxic signs and time of death . Therefore, LD50 value was considered to be >4000 mg/kg bw, when rabbits were treated with test chemical via dermal application.
