Product Overview

Cocamidopropyl betaine (capb) is a widely used, mild, zwitterionic surfactant primarily derived from coconut oil and dimethylaminopropylamine. Celebrated for its exceptional gentleness, cocamidopropyl betaine (capb) is the cornerstone ingredient in"no-tears"baby shampoos. Its key function is as a secondary surfactant that effectively boosts and stabilizes rich, creamy lather while significantly reducing the potential irritation from harsher primary cleansers.
Beyond foam enhancement, cocamidopropyl betaine (capb) acts as a viscosity modifier, thickening liquid formulations into desirable gels, and provides a slight conditioning effect by smoothing hair and skin. This versatility makes cocamidopropyl betaine a fundamental component across personal care, featured in adult shampoos, body washes, facial cleansers, and shaving products.

Product Characteristics
- Gentle Cleansing & Foaming: Cocamidopropyl betaine (capb) is an excellent secondary surfactant that boosts and stabilizes foam, making lather richer, creamier, and more stable. It is much milder on the skin than harsh anionic surfactants like SLS.
- Viscosity Modifier: Cocamidopropyl betaine (capb) helps thicken formulations, giving shampoos, body washes, and hand soaps their desirable, creamy consistency.
- Conditioning Agent: Cocamidopropyl betaine (capb) imparts a soft, smooth feel to hair and skin and can reduce static and flyaways in hair.
- Compatibility Enhancer: Its amphoteric nature helps reduce the irritation potential of other surfactants in a formula, making cocamidopropyl betaine liquid a key component in"no-tear"and"gentle"labeled products.
