Cocamidopropyl Betaine (CAPB / CAB 35%) is an organic compound derived from coconut oil and dimethylaminopropylamine. It is a viscous pale yellow solution widely utilized as a high-performance surfactant in personal care products. The lauric acid group, derived from coconut oil, forms the core of its molecule. It has significantly replaced cocamide DEA in various formulations due to its superior properties.
