Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Studies evaluating the short term toxicity of the substance to aquatic organisms are available for three trophic levels (fish, aquatic invertebrates, algae). An LC50 (96 h) of 0.205 mg/L (geom. mean meas.) was found for fish, an EC50 (48 h) of 11.3 mg/L (arithm. mean meas.) for aquatic invertebrates and an ErC50 (72 h) of 69.2 mg/L (geom. mean meas.) for algae.

Long term toxicity data are available for aquatic invertebrates and algae with a respective NOEC (21 d) of 3.2 mg/L (arithm. mean meas.) and ErC10 (72 h) of 30.2 mg/L (geom. mean meas.).

The substance did not cause inhibition of activated sludge microorganisms, as indicated by the toxicity control of the study on ready biodegradability. A NOEC (28 d) of3 mg/L (nominal) was determined. Therefore, inhibition of the degradation process in sewage treatment plants is not expected.
