Used as a surfactant and emulsifier in personal care products such as shampoos, conditioners, and skin cleansers. It helps stabilize formulations by allowing oil and water to mix, improves foam formation, and enhances product spreadability. Also provides mild conditioning properties, reducing static and improving softness in hair care applications. Common in mild cleansing systems due to its low irritation potential. Frequently used in combination with other surfactants to optimize cleaning and sensory properties.
