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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to the Classification, Labelling and Packaging Regulation EC (No) 1272/2008 the "safety net" classification as Aquatic Chronic 4 (H413) should be considered for poorly soluble substances for which no acute toxicity is recorded at levels up to the water solubility and which are not rapidly degradable and have an experimentally determined BCF ≥ 500 (or, if absent, a log Kow ≥ 4), indicating a potential to bioaccumulate, unless other scientific evidence exists (e.g., chronic toxicity NOECs > 1 mg/L or at the solubility level).
Although the substance is not readily biodegradable, it has an experimentally determined log Pow of 3.56 at 25°C (EU method A.8), indicating only a low potential to bioaccumulate. Further, long-term data is available from a prolonged toxicity study according to OECD 204: NOEC (21d) = 0.33 mg/L (at the solubility level of the substance).
Conclusion on classification
The substance does not need to be classified and labelled according to Regulation (EC) No 1272/2008 of the European Parliament and of the Council, since not all criteria for the "safety net" classification apply here.
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.
