  • Applications

    Steareth-3 (CAS 4439-32-1) is a nonionic surfactant commonly used as an emulsifier and wetting agent in cosmetic and household formulations. In cosmetics and personal care, it helps stabilize oil-in-water lotions, creams, shampoos, and conditioners. In household and industrial cleaners, it improves wetting, detergency, and spreadability. In industrial manufacturing, it serves as an emulsifier and dispersant in degreasers, metalworking fluids, and other formulation concentrates. In coatings and inks, it acts as a pigment dispersant and flow modifier. In polymers and plastics processing, it can function as a processing aid and dispersant for polymer emulsions.
