  • Applications

    Sodium cholesteryl sulfate (CAS 2864-50-8) is commonly used as an anionic surfactant and emulsifier in cosmetic and personal-care formulations, helping stabilize oil-in-water emulsions, supporting wetting and dispersion of pigments in coatings and inks, and acting as a rheology modifier in certain polymer systems. It may also serve as a surfactant or formulation aid in household cleaners and industrial detergents, enhancing cleaning performance and formulation stability. In coatings, inks, and adhesives, it functions as a dispersing agent to improve pigment dispersion and substrate wetting. In polymer and plastic processing, it can stabilize latex emulsions and serve as a specialty surfactant for formulated polymers. It may also be evaluated as an excipient or surfactant component in topical pharmaceutical preparations, subject to regulatory compliance.
