Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Partitioning of
substances into the different environmental compartments depends mainly
on their physico-chemical properties. Since the substance is poorly
soluble in water, not volatile, and has a high adsorption potential, it
is not expected to be found in the air or water compartments. If
released in surface waters, the substance would probably partition from
the water phase to the sediment. Based on physico-chemical properties,
the main target compartments for the substance would thus be soil and
sediment. However, the substance is readily biodegradable and is thus
expected to be eliminated in sewage treatment plants to a high extent.
Release to surface waters, and thereby exposure of sediment, is
therefore very unlikely. Accumulation into organisms is not expected,
since the substance can be digested by common metabolic pathways, as
dietary fats (Berg et al., 2002; Mattson and Volpenheim, 1972; Tocher,
2003).
The fate of the chemicals is also influenced by (bio-)chemical processes
they may undergo in the environment. The substance is readily
biodegradable and is therefore expected to be rapidly eliminated from
the environment. Abiotic degradation is not likely. Hydrolysis and
photodegradation are not relevant, since the substance is not expected
to be present in the water and air compartments. Additionally, estimated
hydrolysis rates are very low at environmental conditions.
In conclusion,2-ethylhexanol nonanoate (CAS 59587-44-9) is
expected to be found mainly in the soil compartment, where a rapid
degradation by microorganisms is expected.
