Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The potential for bioaccumulation of the substance is low - Estimated BCF equal to 22 L/kg whole body w.w.

Key value for chemical safety assessment

BCF (aquatic species):
22 L/kg ww

Additional information

The log Kow of 4.83 indicate that the substance may slightly bioaccumulate.

The BCF of the substance was estimated using accepted calculation methods:

CAESAR BCF v. gives a value of 22 L/kg ww.

EPA BCFBAF v.3.01 gives a value of 714 L/kg ww.

It is therefore concluded that the potential for bioaccumulation of diisobutyl hexahydrophthalate (DIBE) is low.
