  • Applications

    ethanesulfonic acid, 2-(methyl(1-oxotetradecyl)amino)-, sodium salt (CAS 18469-44-8) is used mainly as an anionic surfactant and wetting agent. In practical formulations, it serves as a surfactant in household and industrial cleaners, a pigment dispersant and emulsifier for coatings, paints, and inks, a processing aid to improve wetting and dispersion in polymer and textile formulations, and an ingredient in personal care products for cleansing and solubilizing hydrophobic actives. It may also be used as an intermediate in the synthesis of specialty surfactants and related formulation aids, subject to local regulations and formulation constraints.
