Phototransformation in air is not relevant due to low vapour pressure (< 0.0001 Pa).
No experimental studies investigating the phototransformation in
air of fatty acids, C16-18, 2-octyldodecyl esters (CAS 96690-38-9) are
available. Because the substance is a composition of different
homologues, the phototransformation in air was calculated for
representative components using AOPWIN v1.92 (Müller, 2011). The results
indicate that the components of the test substance are susceptible to
indirect photodegradation in air. The estimated half-life for the
reaction with OH-radicals is 7.81 - 8.28 h (24 h day; OH-concentration:
0.5E+06 OH/cm³). However, this is not expected to be a relevant
environmental fate process, since the components fatty acids, C16-18,
2-octyldodecyl esters are not expected to be present in the atmosphere
based on the low estimated vapour pressure under ambient conditions (<
0.0001 Pa at 20 °C). As this study is not a standard information
requirement in REACh and there is no indication from the Chemical Safety
Assessment (CSA) on the need to investigate further the fate and
behaviour of the substance (Annex X requirement), no further testing is
considered necessary for fatty acids, C16-18, 2-octyldodecyl esters.
