  • Applications

    Stearic monoisopropanolamide (CAS 35627-96-4) is commonly used as a fatty amide surfactant and conditioning agent in cosmetic and personal-care formulations, improving slip, mild emolliency, and gentle cleansing performance. It may also function as an intermediate or specialty surfactant component in household and industrial cleaners, as well as a processing aid in polymers and plastics where it can act as a slip or lubricating additive. In coatings and inks, it can serve as a flow modifier or lubricant to improve leveling and film formation. Additionally, it may be evaluated as a nonionic surfactant or emulsifier in detergent systems, subject to local regulations and formulation limits.
