Used as a surfactant and foam booster in personal care products such as shampoos, body washes, and facial cleansers. It enhances cleansing by reducing surface tension, allowing better spread and penetration of the product. Provides mildness to formulations, making it suitable for sensitive skin. Also improves foam stability and volume, even in hard water. Functions as a viscosity modifier, helping to control the thickness of liquid formulations. Offers conditioning properties in hair care products by reducing static and improving manageability. Commonly used in combination with other surfactants to optimize performance and reduce irritation.
