Other synonyms for abietic acid include abeitic acid, fir resin acid, and juniper resin acid. It is a carboxylic acid that is produced by the oxidation of resinous materials derived from coniferous trees. Abietic acid is used in the manufacture of soaps, varnishes, and adhesives, as well as in the production of paper and textiles.
