Sodium Oleth Sulfate

Sodium Oleth Sulfate is a synthetic surfactant that helps to create lather and clean the skin or hair. It works by reducing the surface tension of water, allowing oil and dirt to mix with water and be rinsed away. It is commonly found in shampoos, body washes, and facial cleansers.
