Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Water solubility
1.9 mg/L (OECD 105)
Partition coefficient
log Kow = > 5.7 (OECD 117)
Degradation
Readily biodegradable: 77.5% after 28 d (301 F)
Aquatic short- term toxicity
Aquatic invertebrates:
EL50 (48 h) > 10.0 mg/L (nominal (WAF), OECD 202, D. magna)
Algae
ErL50 (72 h) = 8.5 mg/L (nominal (WAF), OECD 201, P. subcapitata)
Fish
No toxicity to fish at concentrations up to the water solubility.
Aquatic long- term toxicity
Algae
NOErL (72 h) = 3.13 mg/L (nominal (WAF), OECD 201, P. subcapitata)
Conclusion on CLP
Based on the data above, the substance is rapidly biodegradable and potentially bioaccumulative. The effect concentration for acute aquatic toxicity (L(E)C50) is > 1 mg/L for Daphnia and algae and the effect concentration for long- term aquatic toxicity (NOErL) is > 1 mg/L for the more sensitive trophic level (algae). Therefore, the substance does not need not 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).
