- Executive summary:
A study according OECD TG 423 was conducted to identify potential toxic effects of the test item after single oral administration to rats in a stepwise procedure. The study was started with 2000 mg/kg bw in 3 female rats and continued with further 3 females treated with 2000 mg/kg bw. Mortality and clinical signs were monitored for at least 6 hours after administration and then daily. All animals were weighed before treatment (day 1) and on days 2, 4, 6, 8, 11, 13, and 15. At the end of the observation period, all surviving rats were sacrificed and subjected to a detailed necropsy. No mortality occurred during the course of this study. No clinical signs of toxicity were observed. One rat showed a decrease of body weight on day 2 of the experimental phase. The body weight development of all other rats was inconspicuous throughout the study. The gross pathological examination revealed no organ alterations. The test item has no acute toxic potential under the conditions of the present study, and the LD50 value is higher than 2000 mg/kg after single oral administration in female rats.

Justification for classification or non-classification
Classification, Labeling, and Packaging Regulation (EC) No 1272/2008
The available data is reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. As a result the substance is not considered to be classified for acute oral toxicity under Regulation (EC) No 1272/2008, as amended for the fourteenth time in Regulation (EU) No 2020/217.
