  • Applications

    Disodium 4-(undecylenic monoethanolamide) sulfosuccinate (CAS 26650-05-5) is an anionic surfactant based on a sulfosuccinate core, serving as an emulsifier, wetting agent and dispersant in cosmetics/personal care and household cleaning products. It also functions as a surfactant and processing aid in industrial manufacturing, aiding pigment dispersion in coatings/inks and in polymer formulations. In coatings and paints, it enhances wetting and emulsion stability; in polymer systems it can act as a processing aid and emulsifier to improve solid dispersion. In agrochemical formulations it may serve as an adjuvant to improve spray performance. Its use is formulation-dependent and subject to local regulations.
