  • Applications

    Sodium heptadecanoate is an anionic fatty acid salt commonly employed as a surfactant and emulsifier in various formulations. In cosmetics and personal care, it serves as a mild surfactant and emulsifier in cleansers and shampoos. In household and industrial cleaners, it is used as a biodegradable surfactant in detergents and degreasers. In coatings and inks, it functions as a wetting agent and pigment dispersion aid to improve leveling and stability. In polymer and plastics processing, it may act as an emulsifier or stabilizer in emulsion polymerizations. In agriculture, it may be used as an adjuvant or surfactant to improve spray coverage and formulation stability of agrochemicals. In pharmaceutical formulations, it can serve as a surfactant excipient where such properties are desired. The actual use depends on formulation requirements and regulatory constraints.
