Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 & pathways
Biodegradation
Not readily biodegradable (54.8% after 28 d, OECD 301 F)
Bioaccumulation
log Kow = 1.58 (OECD 117, HPLC method)
Short-term aquatic toxicity
Aquatic invertebrates
EC50 (48 h) = 3.12 mg/L (geom. mean measured, OECD 202, D. magna)
Aquatic algae
ErC50 (72 h) = 0.114 mg/L (geom. mean measured, OECD 202, P. subcapitata)
Long-term aquatic toxicity
Aquatic algae
ErC10 (72 h) = 0.0708 mg/L (geom. mean measured, OECD 202, P. subcapitata)
Conclusion on CLP
According to all the available data compiled above, the lowest available acute and chronic effect concentrations were obtained for aquatic algae, with an ErC10 (72 h) of 0.0708 mg/L and an ErC50 (72 h) of 0.114 mg/L. Furthermore, the substance is not rapidly biodegradable according to OECD criteria and has a low log Kow. On this basis, 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.
