Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Algae: 72 h, ErC50 (Pseudokirchneriella subcapitata): > 100 mg/L (nominal)

Aquatic chronic toxicity

Aquatic invertebrates: no data available

Algae: 72 h, NOEC (Pseudokirchneriella subcapitata): 32 mg/L (nominal)

 

Classification according to CLP

Acute toxicity data are available for all three trophic levels whereas chronic data are only available for algae. The test substance is considered to be not readily degradable, but has a low potential for bioaccumulation (log Kow < 4). Algae and Daphnia were found to be the most sensitive species with ErC50 and EC50 values of > 100 mg/L and > 100 mg/L, respectively. Following Regulation (EC) 1272/2008, 10. ATP (2017) the substance is not classified as acutely as well as chronically hazardous to the aquatic environment.
