Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 3.17 L/kg whole body w.w.

Key value for chemical safety assessment

BCF (aquatic species):
3.17 L/kg ww

Additional information

The BCF and BAF of the substance were estimated using the software BCFBAF v.3.01 to give respectively values of 3.17 L/kg ww and 0.96 L/kg ww.

The Bio Half-Life was estimated to be: 0.13 days (normalized to 10 g fish at 15 deg C).

The primary biotransformation rate constant (kM) was estimated to be: 5.57 /day (10 gram fish).

It is therefore concluded that the potential for bioaccumulation of 1,2,3,6 -tetrahydrophthalimide is low.
