Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Based on an oral limit test with 5000 mg/kg bw where no mortality or any other toxicological symptoms occured within 14 d after application (gavage) in male and female rats, the test item is not classifiable according to CLP criteria.
