Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

EC50 (72h) > 300 mg/L based on nominal rates for growth rate of Desmodesmus subcapitata (OECD 201)

Key value for chemical safety assessment

Additional information

In a GLP guideline study following OECD 201 green algae (Pseudokirchnerella subcapitata) were exposed for 72 hours to

the test item [BASF SE, 2013]. Based on the multicomponent mixture test item, the aquatic toxicity on algae was investigated by using water soluble fractions (WSF) at loading rates of 3.0, 30.0 up to a maximum loading rate of 300 mg test item/L. The 72-h EC50 for growth rate inhibition is determined to be >300 mg/L based on nominal loading rates.
