  • Applications

    Sodium Tridecyl Sulfate (CAS 3026-63-9) is an anionic surfactant commonly used as an emulsifier, wetting agent, and foaming agent in many water-based systems. Typical applications include: in cosmetics/personal care (shampoos, body washes, soaps) for stabilizing emulsions and improving feel; in household and industrial cleaners (dishwashing liquids and surface cleaners) for enhanced wetting and dispersion of cleaning actives; in industrial formulations as a surface-active agent and emulsifier in the production of plastics, coatings, and inks; in polymer and rubber processing where it acts as an emulsifier and stabilizer during synthesis; and in agricultural formulations as an adjuvant to improve spray coverage and droplet spread.
