Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on the solubility of fatty acids, C6-19-branched, calcium salts in water, biodegradation in the environment is most accurately evaluated by separately assessing the fate of its constituents calcium ions and C6-19-branched fatty acid ions (or rather its structural analogue neodecanoate).
The concept of biodegradation is not applicable to calcium ions. In addition, neodecanoic acid (structural analogue of C6-19-branched fatty acids) is not readily biodegradable (11% biodegradation in 28 d) based on results from a standard OECD ready biodegradation test. Therefore, data available for calcium cations and neodecanoate anions (representative for C6-19-branched fatty acid anions) indicate that biotic degradation is not a relevant process for the environmental fate of fatty acids, C6-19-branched, calcium salts.
Key value for chemical safety assessment
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.
