Tall oil, also called "liquid rosin" or tallol, is a viscous yellow-black odorous liquid obtained as a by-product of the Kraft process of wood pulp manufacture when pulping mainly coniferous trees.
The tall oil rosin finds use as a component of adhesives, rubbers, and inks, and as an emulsifier. The pitch is used as a binder in cement, an adhesive, and an emulsifier for asphalt.
The demand is for the tall oil rosin and fatty acids which are used to produce adhesives, coatings, and ink resins. The products find use in lubricants, soaps, linoleum, flotation and waterproofing agents, paints, varnishes, and drying oils.
Demand for tall oil fatty acids (TOFA) and TOFA derivatives, as well as tall oil rosin-based resins are said to be picking up, mostly because of improved economic activity.
