Cocamidopropyl Betaine 30% (CAB)

Cocamidopropyl Betaine 30%, commonly abbreviated as CAB or CAPB, is an amphoteric surfactant derived from coconut oil, specifically fatty acids combined with dimethylaminopropylamine. This versatile chemical serves as a cornerstone in the personal care and cleaning industries due to its exceptional mildness and compatibility with various surfactant types, including anionic, cationic, and nonionic systems. As a zwitterionic compound, it possesses both positive and negative charges, allowing it to function effectively across a wide pH range. In its 30% active concentration aqueous solution, it appears as a clear to slightly pale yellow liquid. CAB is primarily utilized to enhance foam stability, increase viscosity, and reduce the irritation potential of harsher primary surfactants like Sodium Laureth Sulfate. Its biodegradable nature and renewable plant-based origin make it a preferred choice for formulators seeking sustainable ingredients. Furthermore, it provides antistatic and conditioning properties, making it indispensable for high-quality hair and skin cleansing formulations worldwide.
