Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Terrestrial bioaccumulation

There are no relevant measured bioaccumulation data for terrestrial organisms available for the substance. The default QSAR for bioconcentration in earthworms is therefore used:

log BCF = 1.0*logKow– 0.6
