Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The acute oral LD50 was 3.55 g/kg with 95 % confidence limits of 2.45 – 4.65 g/kg.
Executive summary:

The acute oral toxicity of the test substance was assessed. The acute oral LD50 was 3.55 g/kg with 95 % confidence limits of 2.45 – 4.65 g/kg. Therefore no classification is required.
