Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Readily biodegradable (62% in 28 d, 14-d window passed, OECD 301 D)
Bioaccumulation
Log Kow: 2.97 (at 22.7 °C, OECD 117, HPLC method)
Water solubility
2.81 g/L (at 20 °C, pH 6.6, E.U. Method A.6, flask method)
Aquatic acute toxicity
Aquatic invertebrates
EC50 (48 h) = 6.3 mg/L (measured, OECD 202, D. magna)
Algae
ErC50 (72 h) = 20.6 mg/L (geometric mean measured, OECD 201, P. subcapitata)
Aquatic chronic toxicity
Algae
ErC10 (72 h) = 9.40 mg/L (geometric mean measured, OECD 201, P. subcapitata)
Conclusion on Classification
Aquatic invertebrates were the most sensitive trophic level with an EC50 (48 h) of 6.3 mg/L. Since the substance is readily biodegradable and shows no potential for bioaccumulation, it is not classified and labelled for environmental hazards according to 7th ATP of Regulation (EC) No 1272/2008 based on the available data.
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.
