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 rabbit were treated with 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate dermally.
Executive summary:

In a acute dermal toxicity study, rabbits were treated with 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate in the concentration of 5000 mg/kg bw orally. No mortality was observed in treated rabbits at 5000 mg/kg. Therefore, LD50 was considered to be > 5000 mg/kg bw when rabbit were treated with 3,7-dimethylocta-2,6-dien-1-yl 2-methylpropanoate dermally.
