Description of key information

Not relevant due to low vapour pressure.

Key value for chemical safety assessment

Additional information

Based on a QSAR estimation using SRC AOP v1.92, 2-ethylhexyl oleate (CAS 26399 -02 -0) is susceptile to indirect photodegradation in air (Kampara, 2013). The estimated half time for the reaction with OH-radicals is 4.14 to 4.51 hours (24 h day; OH-concentration 0.5E+06). However, this is not expected to be a relevant environmental fate process, since the substance is not expected to be present in the atmosphere based on the low estimated vapour pressure (0.00000024 Pa at 20 °C).As this study is not a standard information requirement in REACH and there is no indication from the CSA on the need to investigate further the fate and behaviour of the substance (Annex X requirement), no further testing is considered necessary.
