EC number: 500-204-4
CAS number: 68334-05-4
Phototransformation in air is not relevant due to low vapour pressure (≤ 0.0001 Pa at 20 °C).
Based on QSAR calculation using AOPWIN v1.92, Fatty acids, C18-unsatd.,
dimers, 2-ethylhexylesters (CAS No. 68334-05-4) is susceptible to rapid
indirect photodegradation in air (Erler, 2001). The estimated half-life
for the reaction with OH-radicals is in the range of 2.2 hours to 2.3
hours (24h day; OH-concentration: 0.5E+06 OH/cm3). However,
photodegradation is not expected to be an important environmental fate
process since the substance is not expected to evaporate into the
atmosphere due to its low vapor pressure of ≤ 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, C18-unsatd., dimers, 2-ethylhexylesters.
