Resin soap

Source: Wikipedia, the free encyclopedia.

Resin soap is a mix of salts (usually sodium) of resin acids (usually mainly abietic acid). It is a yellow gelatinous pasty soap with use in bleaching and cleaning and as a compound of some varnishes. It also finds use in rubber industry.

Resin soap is made by reacting resin acids in wood with

wood pulp
. It is also called Kraft soap.

Acidification of the resin soap produces tall oil.

Pine soap is refined from resin soap via tall oil by acidification, refining and resaponification. [1]
