Science

Mechanism of Action

This ingredient functions as an amphiphilic emulsifier, effectively bridging immiscible oil and water components to create stable cosmetic formulations. On the skin, it forms a lightweight, non-drying film that conditions the surface, enhances hydration by attracting and retaining moisture, and contributes to the integrity of the skin barrier. Its surfactant properties also reduce surface tension, aiding in even product distribution and gentle cleansing.
