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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two different validated QSAR models agree that the substance is predicted to have a bioconcentration factor (BCF) in fish of BCF = 4.676 to 6 L/Kg (equals log BCF = 0.67 to 0.77). The conservative result of 6 L/kg is taken forward as key value. The substance is not expected to bioaccumulate.
Key value for chemical safety assessment
- BCF (aquatic species):
- 6 L/kg ww
Additional information
Bioconcentration factors for the substance were estimated using two different validated QSAR models with the following results. The CAESAR model for bioconcentration factor (BCF) in fish returned the result BCF = 6 (L/Kg) whole body weight, log BCF = 0.77. The Estimation Programs Interface (EPI) Suite United States Environmental Protection Agency BCFBAF Program (v3.00) returned the result BCF = 4.676 (L/kg) wet-wt, log BCF = 0.670.
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.
