Cocamidopropyl Betaine (CAPB)-CAS 61789-40-0
Cocamidopropyl Betaine (CAPB) is a classic coconut-derived amphoteric surfactant widely used in global mild personal care formulas. It combines the advantages of anionic and cationic surfactants, featuring excellent foaming, cleansing, thickening and skin conditioning performance. Different from traditional high-irritation surfactants, it has ultra-mild skin and scalp affinity, effectively reduces formula irritation, and brings soft and non-tight after-use feeling. It can stably compound with various anionic, cationic and non-ionic surfactants to optimize foam fineness and improve product mildness and stability. With excellent hard water resistance and low-temperature formula stability, it is a core green raw material for high-end mild cleansing, baby care and sensitive skin daily chemical products.
