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 10 rabbits were treated with test chemical by dermal application in eye shadow form.
Executive summary:

Acute dermal toxicity study of test chemical was conducted in 10 rabbits at the dose concentration of 2000 mg/kg bw by dermal application in eye shadow form. No mortality was observed at 2000 mg/kg bw. Hence, LD50 value was considered to be >2000 mg/kg bw, when 10 rabbits were treated with test chemical by dermal application in eye shadow form.
