  • Applications

    Potassium Behenoyl Hydroxyproline (CAS 1149374-59-3) is used in cosmetics and personal care as an emollient, mild surfactant, and emulsifier, helping stabilize oil-in-water systems and improve slip in creams, lotions, and cleansers. In household and industrial cleaning products, it functions as a surfactant and dispersant to enhance wetting, soil removal, and formulation stability. In industrial manufacturing, it may serve as a fatty-acid-derived additive to improve compatibility between hydrophobic components and to provide lubrication in processing and formulation work. In coatings and inks, it can act as a surfactant or dispersant to improve pigment dispersion and the stability of complex formulations.
