Additional information
Acute oral
An acute oral toxicity study was performed with 5 Wistar rats per sex/dose. The animals were dosed with 2000 mg/kg bw test substance by oral gavage. The animals were observed for 14 days. No mortality or clinical signs were observed. The body weight of the animals increased during the 14 day observation period. Pathology showed no abnormalities. Under the conditions of the test the LD50 was determined to be > 2000 mg/kg bw (BASF, 1988).
Justification for selection of acute toxicity – oral endpoint
Only study available
Justification for classification or non-classification
Based on the available data, the substance does not have to be classified for acute oral toxicity according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
