  • Applications

    Sodium cetostearyl sulfate (CAS 59186-41-3) is a surfactant and emulsifier commonly used in cosmetics and personal care products (shampoos, body washes, facial cleansers) to improve cleansing, foaming and conditioning properties. It also serves as a mild surfactant and stabilizer in household cleaners and other cleaning formulations. In industrial manufacturing, it acts as a wetting agent, emulsifier and dispersant for polymer latexes, paints and coatings, helping pigment dispersion and product stability. It is employed in coatings and inks to improve wetting and dispersion of pigments. In agricultural formulations, it may be used as an adjuvant or surfactant to enhance spray coverage and spreading of agrochemical products. It may also function as a processing aid or emulsifier in various formulating contexts, subject to local regulations and formulation limits.
