Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

DPHA is unlikely to pose a risk for sediment organisms

Key value for chemical safety assessment

Additional information

Since Bis(2-propylheptyl) heaxanedioate (DPHA) is readily biodegradable, extensive degradation of this substance in conventional STPs will take place and only low concentrations are expected to be released (if at all) into the environment. DPHA will be bioavailable to sediment organisms mainly via feed and contact with suspended organic particles. The key study reports a BCF value of 27, which clearly indicate that rapid metabolism takes place even when log Pow values are above the trigger value of 3. Supporting BCF/BAF values calculated for the parent substance as well its metabolites using BCFBAF v3.01 confirm the experimental result (all well below 2000). Furthermore, aquatic toxicity data show that no effects occur up to the limit of water solubility. Therefore, DPHA is unlikely to pose a risk for sediment organisms in general and long-term testing is thus omitted.
