Description of key information

The acute oral toxicity of the substance was investigated in a GLP study according to OECD TG 423.

All six female rats treated with 2000 mg/kg bw by oral gavage survived the observation period of 14 days, showing no clinical signs, no pathological changes and normal body weight development.

According to the results of this study the substance is not classified for acute toxicity according to CLP-Regulation (EC) No 1272/2008.
