  • Applications

    Sodium stearoyl lactylate (CAS 25383-99-7) is widely used as an emulsifier and surfactant across several industrial applications: in food processing it functions as a dough conditioner and emulsifier for bakery products to improve crumb softness and texture stability; in cosmetics and personal care it serves as an emulsifier and thickener/stabilizer in creams, lotions, and shampoos; in household cleaning products it acts as a surfactant and emulsifier to improve cleaning performance and formulation stability; in industrial manufacturing it is used as an emulsifier, emulsion stabilizer, and processing aid in polymer, coating, and ink formulations to enhance dispersion and system stability.
