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.
Table 1. Test results - cumulative
percentage immobilisation in each treatment over the course of the test
Table 2. Results of analysis of test
media - concentrations of Total Organic Carbon (TOC, mg/L) at the start
and end of the first 24 hour exposure period in the 10000 mg/L nominal
results for short-term toxicity to aquatic invertebrates are summarised
in Table 7.2. A 48h EL50 of between 5000 and 10000 mg/L and a
NOELR of 5000 mg/L have been determined for the effects of DTO on
mobility of Daphnia magna. These values are the lowest of those
obtained in three reliable tests conducted on different samples of DTO.
test organisms were exposed to water-accommodated fractions of the
substance. The values are supported by similar results from two other
of PNECs for the aquatic compartment will be based on data for the
blocks of constituents rather than on data for the whole substance.
