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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
Conclusion on classification
Classification according to CLP
Degradation
Biodegradation: readily biodegradable (73% after 28 d, EU Method C.4-E)
Bioaccumulation
Log Kow: 2.15 - 2.63 at 20 °C, pH 6.4 (OECD 117, HPLC method)
Aquatic acute toxicity
For fish: no data available
For aquatic invertebrates: 48 h, EC50 (Daphnia magna, EU Method C.2): 45.5 mg/L (measured)
For algae/aquatic plant: 72 h, ErC50 (Pseudokirchneriella subcapitata, OECD 201): 22.0 mg/L (nominal)
Aquatic chronic toxicity
For fish: no data available
For aquatic invertebrates: no data available
For algae/aquatic plant: 72 h, ErC10 (Pseudokirchneriella subcapitata, OECD 201): 7.2 mg/L (nominal)
Based on the data above, the substance is considered to be readily biodegradable and has a low potential for bioaccumulation. The acute aquatic toxicity EC50 values are >1 mg/L for aquatic invertebrates and algae. Therefore, the substance does not need to be classified and labelled as acute aquatic hazard according to the 7th ATP of the Regulation (EC) No 1272/2008 (CLP).
For evaluation of chronic classification the ErC10 value for algae toxicity is >1 mg/L. Moreover, no chronic classification is necessary based on the acute data. Therefore, the substance does not need to be classified and labelled as long-term aquatic hazard according to the 7th ATP of the Regulation (EC) No. 1272/2008 (CLP).
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.
