  • Applications

    Lauryl sarcosine sodium (CAS 7631-98-3) is an anionic surfactant commonly used in cosmetics and personal care formulations as a mild cleansing/wetting agent and, in some products, as a conditioning component. It is also employed in household and industrial cleaning formulations for surface activity and emulsification. In industrial manufacturing, it serves as an emulsifier and wetting agent in coatings, inks, and polymer processing, helping stabilize emulsions and improve dispersion. It can function as a processing aid in polymers and plastics and may be used to modify surface properties in adhesives formulations. Its use is typically formulation- and regulation-dependent.
