  • Applications

    Disodium sulfoacetate, CAS 5462-60-2, is the water-soluble sodium salt of sulfoacetic acid and is used primarily as an anionic surfactant component and solubilizer in cleaning, cosmetics/personal care, and related formulations. In industrial manufacturing, it can function as a surfactant and dispersing agent to improve wetting, dispersion, and emulsification in cleaning formulations and coatings. It is also employed as an intermediate in the synthesis of specialty surfactants and polymer additives. Additionally, it may serve as a processing aid or formulation component in coatings, inks, and adhesives to enhance compatibility and solubility of other ingredients. Depending on local regulations and formulation limits, its use is typically as a solubilizing/functional salt within formulated products.
