Science
Mechanism of Action
This ingredient primarily functions as an emulsifying agent, effectively blending immiscible oil and water phases to stabilize cosmetic emulsions. It also acts as a surfactant, reducing the surface tension of formulations, which aids in the even distribution of product across the skin. Its unique ability to bind both water and oils contributes to a pleasant skin feel and may facilitate the optimized penetration of other active ingredients.
