  • Applications

    Sodium Laurate (CAS 629-25-4) is the sodium salt of lauric acid and is used primarily as an anionic surfactant in cleaning and laundry formulations, including household detergents and industrial cleaners. It also serves as a surfactant, emulsifier, and stabilizer in cosmetics and personal care products (shampoos, body washes), improving foaming and emulsion stability. As a medium-chain fatty acid salt, it is commonly used as an intermediate in the synthesis of other surfactants and fatty‑acid derivatives. In industry it functions as a surface-active agent in coatings, paints, and inks, and may be used in agricultural formulations as a fatty‑acid soap-based surfactant for foliar sprays. Subject to local regulations and formulation limits.
