  • Applications

    Sodium Lauroyl Sarcosinate (CAS 137-16-6) is a mild surfactant commonly used in cosmetics and personal care as a cleansing and foaming agent, in products such as shampoos, facial cleansers, and body washes, where it also helps stabilize emulsions and improve skin feel. It is also employed in household cleaning products as a surfactant and degreasing aid, in pharmaceuticals as an excipient and surface-active aid in topical formulations, and as an emulsifier or wetting agent in coatings and inks. In industrial manufacturing and polymer applications it can serve as a processing aid, emulsifier, or stabilizer for formulations and polymer emulsions.
