  • Applications

    Steareth-2 (CAS 16057-43-5) is a nonionic surfactant based on stearyl alcohol ethoxylated with 2 ethylene oxide units. In practice it serves as an emulsifier and surface-active agent in cosmetics and personal care products (creams, lotions, shampoos); as a solubilizer and wetting agent in household and industrial cleaning formulations; as a wetting agent and dispersant in paints, coatings, and inks; as a stabilizer/dispersant in polymer or latex systems; as an additive in adhesives to improve wetting and flow; and as a fragrance oil solubilizer in cosmetic and cleaning formulations.
