  • Applications

    Chemical name: Heptadecanoic acid, potassium salt (1:1) is the potassium salt of the fatty acid and behaves as a surfactant and emulsifier (CAS 17378-36-8). In practice, it is used across industries where surfactant and cleaning properties are needed: as a surfactant/emulsifier in detergents and personal care formulations; as a thickener or rheology modifier for aqueous systems; as a soap component and cleaning agent in household products; as a dispersant or pigment-dispersion additive in coatings and inks to improve pigment stability; as a lubricant or processing aid in polymer and industrial lubricant formulations; and as a surfactant adjuvant in agricultural formulations.
