Science
Mechanism of Action
This ingredient operates by significantly lowering the surface tension of liquids, which allows oil and water to mix more readily. This action is crucial for dispersing and lifting fat and soil particles from the skin and hair, ensuring efficient cleansing. Furthermore, it acts as an emulsifier, stabilizing formulations, and contributes to the production of rich, desirable foam.
