Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
In an acute oral toxicity study in rats, the LD50 (gavage) value of the test item was reported to be greater than 5000 mg/kg bw (test mat.).
Executive summary:

In an acute oral toxicity study according to BASF method, rats were given a single oral dose of the test item at a dose of 5000 mg/kg bw and were observed for 7 days. The LD50 was reported to be greater than 5000 mg/kg body weight.
