Science

Mechanism of Action

This ingredient functions by significantly lowering the surface tension of liquids, which allows water to more effectively interact with and suspend oily residues and particulate matter for removal. As an emulsifier, its chemical structure, featuring phosphoric acid and polyoxyethylene groups, enables the creation and maintenance of stable mixtures from components that would otherwise separate, such as in creams and lotions.
