Science
Mechanism of Action
Functions as a surfactant by positioning itself at the oil-water interface, reducing surface tension to allow oils and impurities to be lifted from skin and rinsed away. Simultaneously acts as an emulsifier, stabilizing oil-in-water formulations by maintaining the structural integrity between aqueous and lipid phases.
