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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 and pathways
Biodegradation
Readily biodegradable: 75% in 28 d (OECD 301 F)
Bioaccumulation
log Kow = 1.94 (20 °C, HPLC method)
Aquatic acute toxicity
Aquatic invertebrates
EC50 (48 h) = 32 mg/L (nominal, OECD 202, D. magna)
Aquatic algae
ErC50 (72 h) = 40 mg/L (nominal, OECD 201, P. subcapitata)
Aquatic chronic toxicity
Aquatic algae
ErC10 (72 h) = 24 mg/L (nominal, OECD 201, P. subcapitata)
Conclusion on CLP
Based on the data above, the substance is readily biodegradable and has no potential for bioaccumulation. The lowest available effect concentration for acute toxicity (Daphnia) is > 1 mg/L and the single effect concentration for long-term aquatic toxicity to aquatic algae (ErC10) is > 1 mg/L. Therefore, the substance does not need to be classified according 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.
