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.

Table 3. Results of TOC analysis of test
results for toxicity to algae and aquatic plants are summarised in Table
7.4. A 72h EL50 of approximately 3300 mg/L and NOELR of approximately
300 mg/L have been determined for the effect of DTO on growth rate of
Scenedesmus subspicatus. These values are the lowest of those obtained
in three reliable tests conducted on different samples of DTO.
is a UVCB substance and compositional information has been used in
conjunction with validated QSARs to derive No Observed Effect
Concentrations (NOECs) for its constituent blocks. Calculation of
long-term PNECs for the aquatic compartment will be based on data for
the constituent blocks rather than on data for the whole substance.
Further testing for long-term toxicity to aquatic algae will therefore
not contribute to the database that is required to complete the
assessment of the substance.
