Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Classification relevant information:
Environmental fate and pathways
Degradation
Not readily biodegradable (21% in 28 d, OECD 310)
Aquatic short-term toxicity
Fish: no data available
Aquatic invertebrates: EC50 (48 h) = 18.98 mg/L (meas., OECD 202)
Algae: EC50 > 58.33 (meas. initial) (OECD 201)
Aquatic long-term toxicity
Fish:No data available
Aquatic invertebrates: No data available
Algae: EC10 (72 h) = 7.41 mg/L (meas. initial, OECD 201)
Conclusion on CLP
Based on the listed data above the substance is not readily biodegradable. Acute toxicity data for two trophic levels resulted in the lowest EC50 of 18.98 mg/L for aquatic invertebrates. Chronic toxicity data are available only for algae with an EC10 (72 h) of 7.41 mg/L. Aquatic invertebrates were however found to be the most sensitive species in acute toxicity studies and no chronic data are available for this trophic level. Therefore, the substance is not classified for acute toxicity hazard and is classified as aquatic Chronic 3 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.
