Cocamidopropyl Betaine (CAS 61789-40-0) is a Cosmetic Grade amphoteric surfactant derived from coconut oil, supplied as a colorless viscous liquid that boosts foam and reduces the irritation of anionic surfactants in shampoos, body washes and liquid soaps, and serves as a biodegradable wetting agent in industrial cleaning. It is widely utilized for its excellent foam boosting capabilities and its ability to reduce the irritation of anionic surfactants.

This high-purity secondary surfactant is effective across a broad pH range and provides mild conditioning properties. It is a Technical Grade essential for formulating clear liquid soaps, shampoos, and sensitive skin cleansing products.

Beyond personal care, it functions as a highly efficient biodegradable wetting agent in industrial cleaning. Its viscous liquid form ensures easy processing and stability in high-performance detergent formulations.
