Science
Mechanism of Action
This ingredient effectively lowers the surface tension of liquids, a key property that enables the fine mixing of components like oil and water that would otherwise separate. This action underpins its role as an emulsifying agent and solubilizer, ensuring product stability and consistency. Furthermore, its functional profile extends to acting as a solvent and a skin conditioning agent, contributing to the overall texture and feel of the skin.
