Cocamide Betaine
What is Cocamide Betaine?
Cocamide Betaine is an amphoteric surfactant synthesized from coconut fatty acids and betaine, a compound found in beets and other plants. Its zwitterionic nature, with both positive and negative charges, enables mild interaction with skin and hair. Primarily used in rinse-off cosmetics such as shampoos, conditioners, body washes, and facial cleansers within the cleansing and hair care categories. It functions by reducing surface tension to lift dirt and excess oils, while boosting foam height and stability for a luxurious lather. Additionally, it thickens formulations for improved spreadability and provides mild conditioning to minimize tangles and static. Its pH-dependent behavior allows compatibility with various surfactant types, supporting gentle yet effective cleaning systems in diverse personal care products.
