  • Applications

    Benzenesulfonic acid, oxybis(dodecyl-, sodium salt (1:2) (CAS 25167-32-2) is an anionic surfactant with two long dodecyl chains attached to a benzenesulfonate core. Typical applications include wetting, emulsifying and pigment-dispersing roles in household and industrial detergents, and in paints and coatings as a pigment dispersant and wetting agent; as a dispersant and stabilizer in polymer latex formulations; as a wetting and leveling agent in textile processing; and as a surfactant component in adhesives and inks to improve compatibility and performance.
