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.
Tall Oil is not explosive based on experience on use and handling and
structural examination of the constituents of the substance.
assessment of explosive properties was conducted using non-experimental
methodology. The potential explosive properties of a substance can be
determined with acceptable reliability directly from the chemical
structure (ECHA 2008). If the substance does not contain any groups
associated with explosivity then a negative result is likely to be
obtained. Chemical structures for the constituents of DTO were examined.
of DTO are not expected to present any hazard associated with explosive
properties based on experience in use and handling. This statement is
supported by the lack of functional groups of concern in the
constituents of DTO and an oxygen balance of –289 for oleic acid and
–286 for linoleic acid, the two main fatty acid constituents, and –281
for abietic acid, a typical resin acid structure in DTO.
oxygen balance of major constituents of DTO was determined with the
mathematical equation below:
+ [x + (y/4)-(z/2)]. O2 → x CO2 + (y/2) H2O
the formula: OB = -1600 [2x +(y/2) -z] / molecular weight.
Number of carbon atoms
Number of hydrogen atoms
Number of oxygen atoms
number of nitrogen and other atoms present is neglected.)
on lack of functional group of concern in the constituents of DTO based
on structural examination and experience in use and handling, it can be
predicted that testing for explosive properties will be negative;
therefore, testing is not conducted for this group of substance.
