Additional information
Oral
The acute oral toxicity of the test substance was assessed in a study according to OECD Guideline 401 and in compliance with GLP (1992). Groups of 5 male and 5 female rats were given a total dose of 2000 mg/kg bw of the test substance via gavage. 2/5 females were killed in extremis ca. 5 h after dosing because they were found in a moribund state. Slight signs of toxicity were observed in all rats treated with the test substance shortly after dosing, completely recovered by Day 2. Thus, an oral LD50 > 2000 mg/kg bw for male and female rats was determined.
Dermal
The acute dermal toxicity of the test substance was assessed in a limit test performed in 5 male and 5 female rats according to OECD Guideline 402 and in compliance with GLP (1991). A single dose of 2000 mg/kg bw of the test substance was applied to the clipped skin of the rats under occlusive conditions for 24 hours. No mortality occured, thus a dermal LD50 > 2000 mg/kg bw for male and female rats was determined.
Justification for classification or non-classification
The available data on acute oral and dermal toxicity of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification.
