Lauryl ether sulfate sodium is widely used as a surfactant in personal care and cleaning products due to its excellent foaming and cleansing properties. It is a key ingredient in shampoos, body washes, and facial cleansers, where it helps to remove dirt and oil effectively while creating a rich lather. In household cleaning products like dishwashing liquids and laundry detergents, it acts as a powerful cleaning agent that breaks down grease and stains. Its mildness on the skin makes it suitable for use in formulations designed for sensitive skin. Additionally, it is often used in industrial applications for its emulsifying and wetting properties, aiding in processes such as textile manufacturing and metal cleaning.
