  • Applications

    Polyglycerin-3 (CAS 20411-31-8) is a multi-hydroxyl polyol commonly used as a humectant and solvent in cosmetic and personal care formulations, aiding moisture retention and formulation stability. It serves as a feedstock for polyglyceryl esters that function as nonionic emulsifiers and surfactants in skincare, hair care, and cleaning products. It acts as a thickener and viscosity modifier in household and industrial formulations to improve texture and processability. In industrial manufacturing, it is used as an intermediate for surfactants and polymer additives, and can serve as a polyol component in polyurethane and other polymer systems. It may also serve as a co-solvent or plasticizer in coatings, inks, and plastics processing, depending on formulation needs and regulatory constraints.
