  • Applications

    Sodium butyl oleate sulfate is an anionic surfactant used as a surface-active agent, emulsifier and wetting aid in a range of formulations. Practical applications include use in household cleaners and cosmetics/personal care products, aiding dispersion and emulsification of oils and fats; functioning as a dispersant and emulsifier for coatings, inks, and polymer latex systems; acting as a processing aid and wetting enhancer in polymer and plastics processing; and may be evaluated as a surface-active additive in agricultural formulations or other industrial formulations, depending on local regulations and formulation limits.
