Cocamidopropyl betaine is widely used in personal care products due to its mildness and conditioning properties. It is a common ingredient in shampoos, body washes, and facial cleansers, where it helps to create a rich lather while being gentle on the skin and scalp. Its ability to reduce irritation makes it suitable for sensitive skin formulations. Additionally, it is often included in baby care products for its soothing effects. In cosmetics, it acts as a viscosity enhancer, helping to thicken formulations and improve texture. Its amphoteric nature allows it to stabilize other surfactants, making it a versatile component in various cleansing and foaming products.
