Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated informationCriteria used for interpretation of results: EU
Conclusions:
The LD50 for phenethyl isovalerate was found to be greater than 5000mg/kg in rabbits.
Executive summary:

In a acute dermal toxicity study, rabbits were treated with Phenethyl isovalerate in the concentration of 5000 mg/kg bw. No mortality was observed in treated rabbits. Therefore, LD50 was considered to be > 5000 mg/kg bw when rabbit were treated with Phenethyl isovalerate dermally.

Based on the above value ,the test material does not classify as an acute dermal irritent.
