Applicant's summary and conclusion
- Interpretation of results:
- study cannot be used for classification
- Conclusions:
- The dermal LD50 (rat, male/female) of registration substance was >2000 mg/kg bw (as test material), corresponding to > 400 mg/kg bw as active ingredient.
- Executive summary:
The acute dermal toxicity of the registration substance was tested in Sprague-Dawley rats according to OECD guideline 402 (1987). A dose of 2000 mg/kg bw test item was applied once by the cutaneous route. No deviations from the methods prescribed by the guideline were reported.
Administration of the test material caused no mortality among the test animals.
Therefore, the LD50 was established above the limit dose of 2000 mg/kg bw in terms of test item as manufactured, corresponding to 400 mg a.i./kg bw.
