  • Applications

    2,3-Bis(2-hydroxyethoxy)propyl octadecanoate (CAS number: 32518-68-6) is commonly used in cosmetics and personal care as an emollient and humectant and can function as a nonionic surfactant or emulsifier in formulations; in coatings and inks it acts as a dispersant and flow modifier; in polymers/plastics it serves as a plasticizer or processing aid to improve flexibility and processing; in industrial manufacturing it can be a processing solvent or lubricant and a formulation aid; in household cleaning products it may act as a surfactant or co-emulsifier to improve cleaning performance; and as an intermediate in the synthesis of other polyether-containing esters.
