Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic acute toxicity
Aquatic invertebrates
24.1 mg/L < EC50 (48 h) < 94.3 mg/L (arithmetic mean measured, EU Method C.2, D. magna)
Algae
ErC50 (72 h) = 62.2 mg/L(geom. mean measured, OECD 201, P. subcapitata)

Algae
ErC10 (72 h) = 26.8 mg/L (geom. mean measured, OECD 201, P. subcapitata)
Conclusion on Classification
The test substance is readily biodegradable and the log Kow is below 4. Two studies are available for aquatic toxicity covering aquatic microalgae and invertebrates . Based on this data the substance does not need to be classified for acute or chronic aquatic hazards according to Regulation (EC) No 1272/2008 (9thATP).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
