Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Degradation
Biodegradation: Readily biodegradable: 83.4% (O2 consumption) after 14 d (OECD 301 C)
Bioaccumulation

Aquatic acute toxicity
Aquatic invertebrates (Daphnia magna): EC50 (48 h) 1.97 mg/L (measured)
Aquatic algae (Pseudokirchneriella subcapitata): ErC50 (72 h) = 1.12 mg/L (measured)
Aquatic chronic toxicity
Aquatic algae (Pseudokirchneriella subcapitata): ErC10 (72 h) = 0.442 mg/L (measured
Classification according to CLP
Based on the data above, the test substance is considered to be readily biodegradable. Acute aquatic toxicity was observed for algae and aquatic invertebrates with EC50 values above 1 mg/L. Valid chronic data are available with an ErC10 (72 h) = 0.442 mg/L for the freshwater algae Pseudokirchneriella subcapitata. Thus, the test substance needs to be classified and labelled as chronic aquatic hazard category 2 according to the consolidated version of Regulation (EC) No 1272/2008 and all further amendements (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.
