Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Fatty acids, C16 -18, zinc salts is readily biodegradable. Based on the solubility in water, its environmental fate is controlled by the mobility of zinc cations and C16 -18 fatty anions under environmental conditions, and by fatty acids degrading via the β-oxidation pathway. Using QSAR (KOCWIN v2.00, EPI Suite v4.1), the log Koc values of hexadecanoic acid and octadecanoic acid were estimated based on the respective logKow with 4.12 and 4.71, respectively. Transport and distribution coefficients are reported for zinc cations, which will be released upon dissolution in water. However, 70 % of zinc is removed from the water column under reference conditions for EU regional waters (EUSES) (see section 5.6.: “removal from the water column”). Please refer to the endpoint summary of the respective assessment entity for further details.
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.
