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.
following aquatic toxicity data are available for classification of DTO:
Reliable short-term LL50/EL50 values have been
determined in tests conducted with water-accommodated fractions (WAFs).
The resulting are >100, between 5000 and 10000 and circa 3300 mg/L for
fish, invertebrates and algae.
NOELR of circa 300 mg/L has been determined in the test with algae
long-term NOELR of ≥1 mg/L has been determined in a test conducted on
the closely-related substance, Crude tall Oil, with aquatic
invertebrates (Daphnia magna).
no classification is considered necessary because the substance is
There are no data for long-term toxicity to fish but it is not
expected that fish would be any more susceptible to the effects of the
substance than invertebrates or algae.
is proposed that DTO should not be classified for aquatic
