  • Applications

    Potassium dodecylbenzenesulfonate (CAS 27177-77-1) is a widely used anionic surfactant that functions as a wetting agent, emulsifier, dispersant and surface-active stabilizer. Real-world applications include use in household and industrial cleaners and detergents to improve cleaning performance; in paints, coatings and inks as a pigment dispersant and surface-active additive; in polymer latex production and emulsion formulations as an emulsifier and stabilizer; and in cosmetic and personal-care formulations as a surfactant ingredient for cleansers and shampoos.
