Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biodegradation
Not readily biodegradable: 9.2% after 29 d (OECD 301 B)
Bioaccumulation
log Pow = < 0.3 (OECD 117, 25 °C, pH 6.5)
Aquatic acute toxicity
Aquatic invertebrates
EC50 (48 h) > 119.1 mg/L (OECD 202, D. magna, based on the mean measured concentration)
Algae
ErC50 (72 h): 0.49 mg/L (OECD 201, D. subspicatus, based on geometric mean measured concentrations)
Aquatic chronic toxicity
Aquatic algae
ErC10 (72 h) = 0.07 mg/L (OECD 201, D. subspicatus, based on geometric mean measured concentrations)
Classification according to CLP
Based on the data above the substance is not rapidly degradable and has a low potential for bioaccumulation. Based on the data for aquatic toxicity the substance needs to be classified and labelled as Acute Cat. 1 (H400) and Chronic Cat. 1 (H410) for environmental hazard according to the consolidated version of Regulation (EC) No 1272/2008 (dated: 01.01.2017) and further amendments (ATPs).
M-factor for acute aquatic toxicity: 1
M-factor for chronic aquatic toxicity: 1
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.
