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 3-methylbutyl benzoate dermally.
- Executive summary:
In a acute dermal toxicity study, rabbits were treated with 3-methylbutyl benzoate in the concentration of 5000 mg/kg bw. No 50 % mortality was observed in treated rabbits at 5000 mg/kg bw. Therefore, LD50 was considered to be > 5000 mg/kg bw when rabbits were treated with 3-methylbutyl benzoate dermally.
