Description
A black, resinous liquid obtained as a byproduct from the sulfate, or kraft, paper pulping of Pine wood. Tall oil contains 35-60% rosin acids and 50-60% fatty acids (oleic and linoleic). It is mixed with lime to produce an inexpensive, oily liquid that dries to a brittle yellow film. Tall oil is used in the manufacture of soaps, greases, paints, alkyd resins, Linoleum, fungicides, cutting oils, and Asphalt emulsions.
