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. Tall oil is the third largest chemical by-product in a kraft mill after lignin and hemicellulose. 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.
