Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

BCF: 13 L/kg wet weight

Key value for chemical safety assessment

BCF (aquatic species):
13 L/kg ww

Additional information

VEGA model

The BCF of the substance was estimated to be: 13 L/kg whole body weight.

BCFBAF model

The BCF of the substance was estimated to be: 231 L/kg ww

The BAF of the substance was estimated to be: 12 L/kg ww.

The Bio Half-Life was estimated to be: 0.0342 days (normalized to 10 g fish at 15 deg C).

The primary biotransformation rate constant (kM) was estimated to be: 20.27 /day (10 gram fish).

The VEGA model was considered as the most documented and reliable model.

It is therefore concluded that the potential for bioaccumulation of tributyl benzene-1,2,4-tricarboxylate (DIPLAST TM 4) is low.
