Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 fate of fatty acids, C9 -13-neo, copper salts in the environment is most accurately evaluated by separately assessing the fate of its constituents copper cations and fatty acids, C9 -13-neo anions. For the fatty acid anions, read-across to neodecanoic acid (as structural analogue of fatty acids, C6-13-neo) is applied.
The concept of biodegradation is not applicable to copper cations since metals are not degraded. However as a result of naturally occurring geochemical processes metal ions can get removed from the water column. Information on “changes in copper speciation, removal from the water-column and the potential of copper remobilization from sediments” are considered as equivalent to “biodegradation of organic substances.
Available data for the structural analogue neodecanoic acid indicate that it is not readily biodegradable (11% biodegradation in 28 days) based on a standard OECD test.
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.
