  • Applications

    Sodium Palmitate (CAS 408-35-5) is a fatty salt that functions primarily as an anionic surfactant and emulsifier. In practical applications, it serves in household detergents and cleaners, cosmetics and personal care formulations as a cleansing and emulsifying agent and to improve texture, industrial manufacturing as a dispersant and emulsifier for polymers, coatings, and inks, and in agricultural formulations as a surfactant or spray adjuvant to improve coverage, and as a base component in traditional soap formulations.
