Applicant's summary and conclusion
- Interpretation of results:
- other: No category (CLP Regulation EC no. 1272/2008)
- Conclusions:
- The LD50 of the test item is higher than 2000 mg/kg body weight by dermal route in rats.
- Executive summary:
The acute dermal toxicity of the test item was studied according to OECD Guideline 402 (GLP study). 5 female Sprague-Dawley rats were tested for a exposure period of 24 h. Initially, a range finding study was conducted at doses of 200, 1000 and 2000 mg/kg bw in one animal per dose. Based on the results of this preliminary study two additional rats were tested at a dose of 2000 mg/kg bw. No treatment related clinical signs of toxicity and mortality were observed. The body weight evolution of the animals remained normal during the study. The macroscopic examination of the animals at the end of the study did not reveal treatment related effects. Based on these results, the test item was found to be non toxic, with an LD50 > 2000 mg/kg bw.
