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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
BCFBAF model v3.01, log Kow method, key data:
BCF = 319.3 L/kg whole body weight
Key value for chemical safety assessment
- BCF (aquatic species):
- 319.3 L/kg ww
Additional information
The bioconcentration factor (BCF) of the substance was estimated with the BCFBAF model v3.01 from EPI Suite v4.1, which fulfilled all OECD principles. This model estimates BCF using two separate estimation methodologies: using the compound's log octanol-water partition coefficient (Kow) and the Arnot-Gobas method. However, the substance is not within the applicability domain of Arnot-Gobas method, therefore this methodology is not taken into account.
The BCF was estimated at 319.3 L/kg (log BCF = 2.504) based on log Kow method of BCFBAF model. This value is retained as the key value for chemical safety assessment.
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.
