A complex combination of tall oil rosin and fatty acids derived from acidulation of crude tall oil soap and including that which is further refined. Contains at least 10% rosin.
The adsorption/desorption of DTO as a whole
substance is not scientifically necessary or meaningful for the purpose
of environmental assessment. However, for risk characterisation, it is
necessary to consider the properties of the individual constituents that
determine their environmental fate. As a consequence, in this section,
only data describing the adsorption/desorption of DTO constituents are
No measured data are available for
adsorption/desorption coefficient (Koc) of DTO constituents.
Calculated values for the constituents of DTO were obtained using KOCWIN
(PFA 2010b). Koc for each block is calculated from the
weighted average for the constituents in the block, the adsorption of
DTO constituent blocks is shown in Table 4.5.
Adsorption/desorption for DTO constituent blocks
Low boiling fatty acids
C16 saturated - C18.3 unsaturated fatty acids
C18 saturated - C24 saturated and unsaturated fatty acids
Tetracosanol and dehydrated sterol
Sitosterols and analoque
assessed because they are high polymeric constituents
