  • Applications

    Diethylene Glycol Diisononanoate (CAS 190282-37-2) is an ester of diethylene glycol and isononanoic acid, used primarily as a plasticizer and solvent in cosmetics and personal care. In cosmetics, it acts as a lightweight emollient and solvent for actives and fragrance oils, improving skin feel and the solubility of waxy or hard-to-dissolve ingredients. In perfumery, it often serves as a fragrance solvent and carrier, helping to distribute aroma within formulations. In polymers and plastics, it functions as a plasticizer for PVC, polyurethane, and polyester resins, enhancing flexibility and processability. In coatings and inks, it can be used as a solvent or supplemental plasticizer to adjust viscosity and cure performance. In adhesives, it may improve flexibility and adhesion. In household products, it is used as a solvent or emollient in cleaners and air fresheners, subject to local regulations and formulation limits.
