EC number: 701-023-5
CAS number: 85408-61-3
Phototransformation in air is not relevant due to low vapour pressure (0.00063 Pa).
No experimental studies investigating the phototransformation in
air of Fatty acids, C16-18 (even numbered) and C18-unsatd., branched and
linear, di- and triesters with trimethylolpropane (former CAS
85005-23-8) 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., branched and linear, di-
and triesters with trimethylolpropane is not expected to enter the
atmospheric compartment based on the low estimated vapour pressure under
ambient conditions (< 0.00063 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., branched and linear, di- and triesters with
