  • Applications

    1-Propoxy-2-propanol (CAS 1569-01-3), also known as propylene glycol monopropyl ether, is primarily used as a solvent and co-solvent in industrial formulations. In paints and coatings, it helps dissolve resins and adjust flow and drying characteristics. In printing inks, it serves as a solvent to control viscosity and substrate wetting. It is a common ingredient in industrial cleaners and degreasers, contributing solvency for oils and greases. In adhesives and sealants, it functions as a processing solvent to improve mixing and pot life. In polymer formulation and processing, it can dissolve or plasticize resins and facilitate processing. In cosmetics/personal care formulations, it may be used as a co-solvent or processing aid where permitted by regulation.
