  • Applications

    Dipropylene glycol monomethyl ether (CAS 20324-32-7) is a versatile solvent used as a primary or co-solvent in coatings and inks, aiding resin dissolution, pigment dispersion and formulation stability; it is also employed as a processing solvent and carrier in polymer and plastic formulations and as a solvent for adhesives and sealants; in cleaning products, it serves as a solvent and humectant to dissolve residues and stabilize formulations in both industrial and household products; in cosmetics and personal care, it functions as a solvent and humectant for fragrance materials, colorants and active ingredients; and it is often used as a co-solvent or processing aid in formulation workflows across multiple industries.
