Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
Environmental fate and pathways
Degradation
Not readily biodegradable: 15% after 28 d (OECD 301 F)
Bioaccumulation
log Kow = 1.82 ((Q)SAR, KOWWIN v1.68)
Aquatic acute toxicity
Fish
LC50 (96 h) = 2.52 mg/L (measured geometric mean, OECD 203, Danio rerio)
Aquatic invertebrates
EC50 (48 h) = 18.6 mg/L (nominal, OECD 202, Daphnia magna)
Algae
ErC50 (72 h) = 5.98 mg/L (nominal, OECD 201, Desmodesmus subspicatus)
Aquatic chronic toxicity
Algae
ErC10 (72 h) = 1.04 mg/L (nominal, OECD 201, Desmodesmus subspicatus)
Classification according to CLP
Based on the data above the substance is not rapidly degradable and has a low potential for bioaccumulation. The effect concentrations for acute aquatic toxicity are above 1 mg/L. Valid chronic toxicity data are available for algae only. The chronic effect concentration ErC10 (72 h) for algae was 1.04 mg/L. Based on the available data, the substance needs to be classified and labelled as chronic 2 for environmental hazards, according to the consolidated version of Regulation (EC) No 1272/2008 (dated: 01.01.2017) 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.
