Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

Based on the results obtained in this study the median lethal dose value (LD50) of the substance for the male and female rat is greater than 2000 mg/kg body weight.

Executive summary:

Study conducted to EU test guidance 92/69/EEC part B3 and OECD test guideline 402 in compliance with GLP.

Based on the results of the study the LD50 > 2000 mg/kg body weight. The substance is not classified as harmful by acute dermal exposure.
