Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Bioaccumulation: aquatic / sediment
BCFBAF model of Estimation Programs Interface was used to predict the bioconcentration factor (BCF) of test chemical. The bioconcentration factor (BCF) of test chemical was estimated to be 3.162 L/kg whole body w.w (at 25 deg C) which does not exceed the bio concentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
Additional information
Bioaccumulation: aquatic / sediment
Predicted data and various experimental studies of the test chemical were reviewed for the bioaccumulation end point which are summarized as below:
In a prediction done using the BCFBAF Program of Estimation Programs Interface was used to predict the bioconcentration factor (BCF) of test chemical. The bioconcentration factor (BCF) of test chemical was estimated to be 3.162 L/kg whole body w.w (at 25 deg C).
In a supporting weight of evidence study from authoritative databases (2017) for the test chemical,bioaccumulation experiment was conducted for estimating the BCF (bioaccumulation factor) value of test chemical. The bioaccumulation factor (BCF) value was calculated using a logKow of 3.24 and a regression-derived equation. The estimated BCF (bioaccumulation factor) value of test chemical was determined to be 62 dimensionless.
For the test chemical, the bioaccumulation study in fish was conducted for determining the BCF (bioaccumulation factor) value of test chemical (HSDB and PubChem, 2017). The BCF (bioaccumulation factor) of test chemica in fish was determined to be < 10 dimensionless.
On the basis of above results for test chemical, it can be concluded that the BCF value of test chemical evaluated to be upto 62,which does not exceed the bioconcentration threshold of 2000, indicating that the test chemical is not expected to bioaccumulate in the food chain.
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).
