Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Using the validated CAESAR BCF model, the BCF of the substance was estimated to be 126 L/kg.
Using the BCFBAF tool of EpiSuite 4.0, the maximum BCF of the substance was given by the regression-based method as 352.8 L/kg.
Key value for chemical safety assessment
- BCF (aquatic species):
- 352.8 L/kg ww
Additional information
For the registered substance, no study on bioaccumulation was available. However, the BCF was determined with the two QSARs, i.e. the CAESAR BCF model and the BCFBAF tool of EpiSuite 4.0. With BCF of 126 L/kg and a maximum of 352.8 L/kg , respectively, both QSARs gave comparable results.
The overall maximum BCF of 352.8 L/kg, which was obtained with the regression-based method of the BCFBAF tool of EpiSuite 4.0, was considered as key value.
Considering this value, the supposed metabolism, i.e. cleavage into respective acid and alcohol, and the readily biodegradability, which considerably reduces exposure of the aquatic compartment, a bioaccumulation study in fish is not expected to contribute to the assessment of the substance. Therefore, the respective vertebrate study is considered to be scientifically not justified.
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.
