Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 bioaccumulation potential of DCDPS in water breathing organisms is considered low and poses no concern.

Key value for chemical safety assessment

BCF (aquatic species):
82 L/kg ww

Additional information

DCDPS has a low tendency for bioaccumulation in aquatic systems. It is characterized a polar non-volatile substance, having no tendency for enrichment in aquatic systems due to the low log Kow < 4 (Kelly et al 2004, Gobas et al 2009). Fish concentrated non-radiolabelled DCDPS in the experiment by a factor of 75 to 82 L/kg whole body ww (NITE 2002), confirming a low potential for bioconcentration.
