Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Metal carboxylates such as zinc bis(2-ethylhexanoate) are substances consisting of a metal cation and a carboxylic acid anion. Based on the solubility of zinc bis(2-ethylhexanoate) in water, a complete dissociation of zinc bis(2-ethylhexanoate) resulting in zinc cations and 2-ethylhexanoic acid anions may be assumed under environmental conditions. Abiotic degradation is not relevant for zinc cations. Zinc cations and 2-ethylhexanoic acid anions are not subject to hydrolysation as both ions lack hydrolysable groups. Therefore, abiotic degradation via hydrolysis is not considered to significantly affect the fate of zinc bis(2-ethylhexanoate) in the environment. After evaporation or exposure to the air, 2-ethylhexanoic acid will be slowly degraded by photochemical processes with OH-radicals.
