Cocamidopropyl Hydroxysultaine

Also known as: CAHS, Coco-Betaine Hydroxysultaine

Cocamidopropyl Hydroxysultaine is a mild amphoteric surfactant derived from coconut oil. It is commonly used as a co-surfactant to boost foam, improve viscosity, and reduce the irritation potential of other, harsher cleansing agents. It helps create a rich, stable lather and leaves a soft feel.
