Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 of 2 -ethylhexanoic acid, copper salt in the environment is most accurately evaluated by separately assessing the fate of its moieties copper cations and 2-ethylhexanoate anions. Whereas 2-ethylhexanoate is readily biodegradable, the concept of biodegradation is not applicable to copper cations since metals are not degraded. However as a result of naturally occurring geochemical processes copper ions are 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".


In sum, the moieties of 2-ethylhexanoic acid, copper salt are biodegraded or removed from the water column.
