  • Applications

    Sodium Linoleate (CAS 822-17-3) is an anionic surfactant commonly used as an emulsifier and wetting agent in personal care formulations (shampoos, cleansers) and household cleaners. It also serves as a surfactant and detergent component in industrial cleaning products. In polymers and coatings, it can act as an emulsifier or stabilizer in latex systems and plastic processing, aiding pigment dispersion and wetting in coatings and inks. Additionally, it may function as an additive in agricultural formulations as an emulsifier or wetting agent to improve spray coverage and formulation stability, and it can serve as an intermediate for synthesizing other surfactants or esters. Use is subject to local regulations and formulation limits.
