Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 zinc bis(2-ethylhexanoate) in the environment is most accurately evaluated by separately assessing the bioaccumulative potential of its dissociation products, zinc cations and 2-ethylhexanoic acid anions.


Zinc: Due to homeostatic control mechanisms, bioaccumulation is not relevant for essential elements such as zinc. Data indicate that the bioaccumulation potential of zinc in herbivorous and carnivorous mammals is low.


2-ethylhexanoic acid: Due to the low logPow, accumulation in organisms is not expected.
