Cocamidopropyl Betaine (Cocamidopropyl Betaine)

Cocamidopropyl Betaine is a mild amphoteric surfactant widely used in cosmetic and personal care formulations to deliver gentle cleansing, foam boosting, and improved rinse feel. It is commonly included to reduce the perceived harshness of primary anionic surfactants, enhancing lather creaminess and supporting a softer, less-stripping after-feel—especially in sensitive-skin and daily-use cleansing systems. As part of a surfactant blend, it can contribute to viscosity building, improve solubilization of oils and soils, and help stabilize foam across a range of pH conditions. Cocamidopropyl Betaine is frequently found in facial and body cleansers, shampoos, shower gels, hand washes, bubble baths, and intimate hygiene products, as well as in micellar-style formats. Use level and performance are formulation-dependent and typically optimized with the overall surfactant package, electrolyte content, and preservative strategy to achieve the desired clarity, foam profile, and mildness.
