Science
Mechanism of Action
This compound primarily functions by reducing the surface tension of cosmetic products, thereby enabling more uniform application and distribution. As an emulsifier, it is crucial for creating and maintaining stable blends of otherwise immiscible oil and water components. Its surfactant properties allow it to efficiently bind to and remove dirt and other impurities from the skin.
