  • Applications

    Chemical name: Sodium 2-[(1-oxododecyl)amino]ethanesulphonate, CAS 70609-66-4. This anionic sulfonate surfactant is used as a wetting agent, emulsifier and dispersant in a range of formulations. Typical applications include cosmetics/personal care (cleansers and shampoos), household and cleaning products (dishwashing liquids and surface cleaners), industrial manufacturing (emulsification and stabilization of polymer latices, and as a wetting and dispersing aid in paints, coatings and inks), coatings/inks (enhanced wetting, leveling and pigment dispersion), and agricultural formulations as a spray adjuvant to improve coverage.
