Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 estimated bioconcentration factor (BCF) for Eicosanoic acid is 3.2, which does not exceeds the bioconcentration threshold of 2000.Thus, it is concluded that Eicosanoic acid is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.  

Key value for chemical safety assessment

BCF (aquatic species):
3.2 dimensionless

Additional information

Bioaccumulation is the process by which the chemical concentration in an aquatic organism achieves a level that exceeds that in the water, as a result of chemical uptake through all possible routes of exposure. The relationship between bioaccumulation and bio-concentration is that, chemicals that have the potential to bioconcentrate also have the potential to bioaccumulate. Bioaccumulation is closely related to the Bioconcentration factor (BCF).

The estimated BCF of the key study was obtained to be 3.2.Supporting study also indicate the same BCF value as the key study.This low value of BCF of Eicosanoic acid indicates its non bioaccumulative nature as the BCF factor is less than the bio-concentration threshold of 2000.
