Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
In accordance with Annex IX column 2 of the REACH Regulation, a study for bioaccumulation does not need to be conducted if the substance has a low potential for bioaccumulation. The experimentally derived Log Pow value for the substance has been identified as > 9.4. ECHA Guidance on information requirements and chemical safety assessment Chapter R.11: PBT Assessment, page 70 (Molecular weight and log Kow) state that the compound is unlikely to bioaccumulate due to the relatively high molecular weight and a log Kow of >8. A study is therefore considered scientifically unjustified with regard to the low bioaccumulative potential of the substance.

Additional information
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.
