Cocamidopropyl betaine is a mild surfactant derived from coconut oil. It is commonly used in personal care products like shampoos, body washes, and facial cleansers. Its primary function is to help create foam and improve the texture of these products, making them feel smoother on the skin. In addition to its cleansing properties, cocamidopropyl betaine also acts as a conditioning agent. It helps to reduce irritation and enhance the moisturizing effects of other ingredients. This makes it a popular choice for formulations aimed at sensitive skin, as it is generally considered safe and gentle.
