Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Due to the high molecular weight of the substance a crossing of biological membranes is not expected. In addition, according to the Guidance on information requirements and chemical safety assessment, Chapter R.11 (ECHA, 2012), a molecular weight higher than 1100 g/mol is an indicator that the aquatic BCF of the respective substance is lower than 2000 L/kg. This is confirmed by a calculated BCF/BAF of 0.89 L/kg (BCFBAF v3.01 Arnot Gobas, upper trophic level). Thus, in accordance with column 2 of EC 1907/2006 Annex IX, a study on bioaccumulation in aquatic species does not need to be conducted.
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.
