Mechanism of Action
This ingredient functions by reducing the surface tension between immiscible liquids, such as oils and water, allowing them to form stable emulsions. As a surfactant, it aids in cleansing by enabling water to effectively mix with and rinse away oil-based impurities and dirt from the skin. Furthermore, PEG-3 Diisostearate possesses the capacity to enhance the dermal absorption of other compounds within a formulation.
