Science

Mechanism of Action

As a sulfosuccinate monoester anionic surfactant, Disodium Oleyl Sulfosuccinate functions by significantly reducing the surface tension of water. This action facilitates the dispersion of immiscible phases, enabling efficient cleansing, foaming, and emulsification in cosmetic preparations. It further exhibits effective dispersing, wetting, solubilizing, and permeating capabilities.
