  • Applications

    Stearamidopropyl Betaine, CAS 6179-44-8, is an amphoteric fatty amide-derived surfactant widely used in cosmetics and personal care such as facial cleansers, shampoos, and shower gels due to its mildness, foam stability, and conditioning effects on skin and hair. It is also commonly used in household cleaning and laundry products as a mild surfactant, foam booster, and emulsion stabilizer. In industrial polymer processing, it serves as an emulsifier and/or dispersant, and is used as a surfactant additive in coatings, inks, and finishes to improve dispersion and softness of the system. Additionally, it can be considered a mild conditioning agent in hair care formulations.
