Science
Mechanism of Action
This ingredient functions by significantly lowering the interfacial tension between typically incompatible phases, like lipids and aqueous solutions. As an emulsifier, it stabilizes formulations, preventing phase separation. As a surfactant, it facilitates the removal of skin oils and impurities through emulsification, and as a solubilizer, it allows hydrophobic compounds like fragrances to be uniformly dispersed in water-based systems.
