Function

BUFFERING: Stabilising the pH of an aqueous medium in a narrow range even if an acid or base is added. Altering and/or maintaining a cosmetic product's pH at the desired level.
CHELATING: Forming complexes with metal ions which could affect the stability and/or appearance of cosmetics.
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 - HYDROTROPE: Enhancing the water solubility of another surfactant.
