EC number: 701-042-9
CAS number: 1335202-94-2
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 even numbered and C18-unsatd. triesters with
propylidynetrimethanol (CAS 57675-44-2) are available. Results from
AOPWIN v1.92 indicate that the substance is susceptible to indirect
photodegradation in air. The estimated half-life for the reaction with
OH-radicals is 1.5 - 6.1 h (24 h day; OH-concentration: 0.5E+06 OH/cm³)
(Müller, 2013). However, this is not expected to be a relevant
environmental fate process, since fatty acids, C16-18 even numbered and
C18-unsatd. triesters with propylidynetrimethanol is not expected to
enter the atmospheric compartment 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, no further
testing is considered necessary for fatty acids, C16-18 even numbered
and C18-unsatd. triesters with propylidynetrimethanol.
