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 study does not need to be conducted
because the partition coefficient of a UVCB substance of this nature
should be evaluated on the basis of the properties of its constituents.
A result for the whole substance is not meaningful scientifically for
the purpose of assessment of exposure or risk. It is therefore not
appropriate to conduct or propose a test for this endpoint. The needs
associated with a sound understanding of partition coefficient are
adequately met by the available data on constituents. Reliable partition
coefficient data are characterised by quantitative structure activity
relationships (QSARs) for constituents of the substance.
In a supporting study conducted according to
OECD 117, a partition coefficient of 4.9 - 7.7 and 3.2 - 6.8 at pH 2 and
pH 5 - 6 was obtained for Distilled Tall Oil respectively.
