Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aquatic toxicity
Two reliable QSAR models were used to assess the aquatic toxicity of the registered substance to fish, aquatic invertebrates and algae: iSafeRat holistic approach v1.7 and ECOSAR v1.11 models. Both QSAR results are reliable as the registered substance falls within the applicability domain of the models and were used as key data points. Therefore, the E(L)C50 key values, used for chemical safety assessment, were determined as the geometric mean of predicted E(L)C50 values, corresponding to 24.33 mg/L for aquatic invertebrates and 13.23 mg/L for algae.
Finally, the registered substance is considered readily biodegradable and no inhibition effects of the activity of microorganisms was observed in the biodegradation study.
Environmental fate and pathways
The registered substance is readily biodegradable and therefore is not considered persistent. In addition, the registered substance has a low potential for adsorption based on the low octanol water partition coefficient (log Kow = 2.8).
Conclusion on classification
No harmonised classification is available on the registered substance.
10 < lowest E(L)C50 value < 100 mg/L; readily biodegradable; log Kow lower than 4.0 (= 2.8).
Classification according to the Annex VI of the Regulation (EC) No 1272/2008 (CLP): The registered substance is not classified for the aquatic environment.
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.
