EC number: 232-304-6
CAS number: 8002-26-4
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.
preliminary estimate of water solubility was dependent on loading

from the mean calculation and range, as it appears that the sample
may not have been cleaned up sufficiently, compared to samples 1 and
3, hence the high result.
Water solubility: 4.22 x 10-2 g/L at 20°C, pH 4 - 4.1 (OECD 105).
Water solubility has been determined in a
GLP study for the test substance using a method in accordance to OECD
105. DTO has a water solubility of 4.22 x 10-2g/L at 20°C, pH
4 - 4.1. The data is most recent, considered reliable and has been
selected as key study. The result sums the contribution of all
other supporting studies, a water solubility of 9 mg/L is also reported
for the test substance in its entirety as a complex substance using the
same method as stated above. The water solubility of samples of DTO with
resin acid contents of 10 and 40% has been determined in accordance with
OECD 105, respective values of 8.4 mg/L and 8.7 mg/L have been
determined for the samples at 20°C.
test substance is considered slightly soluble.
