  • Applications

    Dehydroabietic acid (CAS 1740-19-8) is a rosin-derived diterpene carboxylic acid that serves mainly as a building block for rosin derivatives used in coatings, varnishes, and inks. It functions as a tackifying resin in polymer formulations and pressure-sensitive adhesives, improving adhesion, processing, and film formation. It is also used as a feedstock for synthesizing specialized plasticizers and stabilizers for plastics and coatings. In cosmetics and personal care, it may be incorporated as a resin component or fragrance fixative. In household products, it can act as a resin modifier and tackifying agent in cleaners and furniture polishes.
