Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test materials was evaluated for acute oral toxicity in fixe male and five female Sprague Sawley rats. The test material was administered by gavae to each of ten rats at a level of 5 g/kg bw. All animals survived the 15 day post administration observation period. Based on this result, the acute oral LD50 of the substance is considered to be greater than 5 g/kg bw.
