  • Applications

    Dipropylene glycol monoethyl ether (CAS 10143-32-5) is a versatile glycol ether solvent commonly used as a solvent and co-solvent across multiple industries. In coatings and inks, it serves as a resin solvent and helps improve film formation and leveling. In cleaning formulations, it acts as a solvency component and co-solvent for active ingredients and surfactants, enabling effective degreasing and residue removal. In cosmetics and personal care, it functions as a solvent and humectant, aiding the dissolution of active ingredients and improving formulation texture and stability. In polymers and plastics processing, it can act as a processing solvent or processing aid for resin systems and adhesives, facilitating formulation processing. It may also be used as a solvent carrier in fragrance formulations, helping to dissolve aromatic compounds and stabilize blends. All use is subject to local regulations and formulation limits.
