Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 environmental fate of zinc bis(2-ethylhexanoate) in the environment is most accurately evaluated by separately assessing the fate of its dissociation products, zinc cations and 2-ethylhexanoic acid anions.
Zinc: Biodegradation is not applicable for metals including zinc. However, information is available on the removal of zinc ions from the water column. The removal from the water column was modeled referring to the EUSES model parameters and different conditions of pH, resulting in a removal of > 70% of total zinc ions under the reference conditions for EU regional waters (EUSES). Consequently, zinc is considered as equivalent to being ‘rapidly degradable” in the context of classification for chronic aquatic effects.
2-ethylhexanoic acid: 2-ethylhexanoic acid is readily biodegradable according to OECD TG 301E (99% removal after 28 d).
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
