Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 algae
ErC10 (72 h) = 0.0525 mg/L (time weighted average, OECD 201, P. subcapitata)
Classification according to CLP
Based on the data compiled above, the substance is not readily biodegradable and has a log Kow ≥ 4.0. The lowest available acute effect concentration (EC50 (48 h)) was < 1 mg/L and was obtained for aquatic invertebrates. The single chronic effect concentration for aquatic algae (ErC10 (72 h)) was also < 0.1 mg/L. Therefore, the substance is classified and labelled as acute 1 and chronic 1 for environmental hazards, according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
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.
