  • Applications

    Ammonium cumenesulfonate (mixed isomers), CAS 37475-88-0, functions primarily as an anionic surfactant and a dispersion/wetting aid in aqueous systems. In practice it is used as a component in cleaning and detergent formulations, including household and industrial cleaners, to improve emulsification and soil removal. It also serves as an emulsifier and pigment dispersant in coatings, inks, and paints, aiding wetting and stability of formulations. In textile and paper processing it provides wetting and dispersion properties for processing chemicals and dyes. It can be used as an intermediate or building block in the synthesis of more complex surfactants and specialty chemicals. Additionally, it may be evaluated for use in polymer formulations and water-based systems as a dispersant or stabilizer, subject to formulation limits and local regulations.
