  • Applications

    Butanedioic acid, 2-sulfo-, 1,4-didecyl ester, sodium salt (1:1) is an anionic surfactant used as an emulsifier and wetting agent in a range of formulations. In household and industrial detergents and cleaners, it improves wetting, emulsification, and soil dispersion. In coatings, paints, and polymer latexes, it acts as a dispersant and emulsifier to stabilize nonpolar components and support film formation. In cosmetics and personal care, it functions as a surfactant and wetting agent to enhance spreadability and product stability. It may also serve as a processing aid or stabilizer in polymer manufacturing and as an adjuvant in agricultural formulations to improve spray coverage. Use is subject to local regulations and formulation limits.
