Applicant's summary and conclusion

Interpretation of results:
Category 5 based on GHS criteria
LD50 was considered to be > 3000 mg/kg bw when Guinea pigs were treated with aluminum trioctadecanoate orally.
Executive summary:

In a acute dermal toxicity study, Guinea pigs were treated with aluminum trioctadecanoate in the concentration of 3000 mg/kg bw dermally. No mortality were observed in treated Guinea pigs at 3000 mg/kg bw. Therefore, LD50 was considered to be > 3000 mg/kg bw when Guinea pigs were treated with aluminum trioctadecanoate orally.
