Applicant's summary and conclusion

Interpretation of results:
other: not classified
Conclusions:
The LD50 value was considered to be >6000 mg/kg bw,when ratbbits were treated with test chemical by dermal application.
Executive summary:

In acute dermal toxicity study, rabbits were treated with test chemical in the concentration of 6000 mg/kg bw by dermal application.No mortality was observed in treated rabbits at dose 6000 mg/kg bw.Therefore, LD50 value was considered to be >6000 mg/kg bw,when rabbits were treated with test chemical by dermal application.
