Endpoint summary
Administrative data
Description of key information
A single dose of the test item was administered orally or dermally to Wistar rats at concentrations of 2000 mg/kg bw. No mortality occurred. Clinical examiniation and gross necropsy did not reveal any findings. The LD50 after oral and dermal administration is therefore considered to be > 2000 mg/kg bw.

Additional information
A single dose of the test item was administered by gavage to female Wistar rats at concentrations of 2000 mg/kg bw. The animals were observed for 14 days. Mortality, body weight and clinical signs were recorded continuously. Organ weighing and gross necropsy was performed after scheduled sacrifice.
A single dose of the test item was applied onto skin of male and female Wistar rats at concentrations of 2000 mg/kg bw. The animals were observed for 14 days. Mortality, body weight and clinical signs were recorded continuously. Organ weighing and gross necropsy was performed after scheduled sacrifice.
No mortality occurred, body weight and body weight gain were comparable to control animals. Clinical signs of toxicity were not observed and gross necropsy did not reveal any findings. The LD50 is therefore considered to be > 2000 mg/kg bw.
Justification for classification or non-classification
Dangerous Substance Directive (67/548/EEC)
The available studies are considered reliable and suitable for classification purposes under 67/548/EEC. As a result the substance is not considered to be classified for acute toxicity under Directive 67/548/EEC.
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance is not considered to be classified for acute toxicity under Regulation (EC) No. 1272/2008.
