  • Applications

    Potassium Xylenesulfonate (CAS 30346-73-7) is primarily used as an anionic surfactant and dispersing agent in a range of formulations across cleaning, coatings, and textile processing. In household and industrial cleaners, it functions as a wetting and emulsifying agent to improve stain removal and pigment dispersion. In paints, coatings, and inks, it acts as a pigment dispersant and leveling aid to stabilize suspensions and enhance flow. In textile processing, it serves as a wetting agent and dyeing auxiliary to promote even dye uptake and fiber finishing. It may also be used as a processing additive in plastics and polymer formulations to improve pigment dispersion and formulation stability.
