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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Conclusion on classification
Environmental fate and pathways
Biodegradation
Not readily biodegradable (39% after 28 d, OECD 301 F)
Bioaccumulation
log Kow = 3.96 (OECD 117, 21.9 °C, HPLC method)
Acute aquatic toxicity
Aquatic invertebrates
EC50 (48 h) = 8.30 mg/L (initial measured test item concentration, OECD 202, D. magna)
Aquatic algae
ErC50 = 8.72 mg/L (time weighted average, OECD 201, S. subspicatus)
Chronic aquatic toxicity
Aquatic algae
ErC10 = 6.10 mg/L (time weighted average, OECD 201, S. subspicatus)
Conclusion on CLP
Acute effect concentrations are available for two trophic levels (aquatic invertebrates and microalgae) and are in the same order of magnitude. Since both EC50 values are > 1 mg/L the substance is not classified for acute hazards to the environment. The substance is classified as Aquatic Chronic 2 (H 411) for long-term hazards for the environment since it is not rapidly biodegradable and has a chronic effect value of 6.10 mg/L for aquatic algae (ErC10, 72 h), and an acute effect value for aquatic invertebrates of 8.30 mg/L (EC50, 48 h), 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.
