  • Applications

    Potassium Linoleate (CAS 3414-89-9) is the potassium salt of linoleic acid, acting as an anionic surfactant and emulsifier. In practice, it is used as (1) a surfactant and emulsifier in household and industrial cleaners; (2) an ingredient in cosmetics and personal care formulations as an emulsifier and stabilizer for oil-in-water emulsions; (3) a raw material or intermediate for soap production and fatty-acid–based polymer systems; (4) a wetting and dispersing agent in coatings, paints and inks.
