Surfactants, one of the major ingredient of cosmetic products, are characterized by their tendency to concentrate at interfaces and to alter the free energy of the interfaces. Through interfacial processes such as wetting, emulsification, solubilization, dispersion and modification of interfacial viscosity and electrical charge, surfactants can mix various ingredients in cosmetics (oil phase, water phase, solids, pigments, dyes, perfumes, enzymes and other additives) into a stable and homogenous system.
