Function

CLEANSING: Helping to keep the body surface clean.
FOAMING: Trapping numerous small bubbles of air or other gas within a small volume of liquid by modifying the surface tension of the liquid.
SURFACTANT - CLEANSING: Wetting body surfaces, emulsifying or solubilizing oils, and suspending soil (generally, such ingredients contribute to the foaming and lathering properties of cleansing products).
SURFACTANT - EMULSIFYING: Helping suspensions or dispersions of liquids in a second liquid by reducing the surface tension of the substances to be emulsified.
