Applicant's summary and conclusion

Interpretation of results:
Category 5 based on GHS criteria
Conclusions:
LD50 was considered to be >5000 mg/kg bw, when rabbits were treated with 7-methyloctyl acetate by dermal application.
Executive summary:

The acute dermal toxicity study was conducted by using 7-methyloctyl acetate in rabbits at the concentration of 5000 mg/kg. No morality was observed in rabbits at 5000 mg/kg. Hence, LD50 was considered to be >5000 mg/kg bw, when rabbits were treated with 7-methyloctyl acetate by dermal application.
