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.
EMULSION STABILISING: Helping the process of emulsification and improving emulsion stability and shelf-life.
HAIR CONDITIONING: Enhancing the appearance and feel of hair. Leaving the hair easy to comb, supple, soft and shiny and/or imparting volume, lightness, gloss, texture, etc.
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.
