emulsifying surfactant

Science

Operating at the interface of disparate phases, ISOMYRETH-9, as an emulsifier, facilitates the uniform dispersion of oil within water or vice-versa, preventing separation in cosmetic emulsions. Its surfactant properties concurrently minimize surface tension, improving ingredient spreadability and supporting efficient cleansing actions on the skin by helping to lift impurities.
