Classification according to CLP

Acute toxicity data are available for all three trophic levels whereas chronic data are available for algae and Daphnia. The test substance is considered to be rapidly degradable and has a low potential for bioaccumulation (log Kow < 4). Daphnia was found to be the most sensitive species with a 21 d-NOEC of 1.3 mg/L. Following Regulation (EC) 1272/2008, 10. ATP (2017) the substance is not classified as acutely as well as chronically hazardous to the aquatic environment.
