  • Applications

    Sorbitan trioctadecanoate (CAS 26658-19-5) is a lipophilic nonionic surfactant commonly used as an emulsifier and stabilizer in formulated products. In cosmetics and personal care, it acts as an emulsifier and lipophilic emollient to help stabilize oil-in-water blends and improve texture. In coatings and inks, it serves as a dispersing agent and surfactant that enhances pigment compatibility and flow. In household and cleaning formulations, it functions as a surfactant and lubricant/softening additive to improve soil removal and formulation stability. In polymers/plastics processing, it can act as a compatibilizer or processing aid, reducing interfacial tension between dissimilar phases. In pharmaceutical formulations, it may be used as a solubilizer or lipid-based formulation component, subject to regulatory limits. Overall, its applications center on emulsification, stabilization, and lipophilic enhancement in various media.
