Micelles are the structures that surfactants form when they reach a certain concentration in water. The surfactant must have a strongly polar “head” and a non-polar hydrocarbon chain “tail”. When this type of surfactant is added to water, the non-polar tails of the molecules clump into the centre of a ball-like structure called a micelle, because they are hydrophobic or “water-hating”. The polar head of the molecule presents itself for interaction with the water molecules on the outside of the micelle. Oil droplets can “hide” from the water in the middle of the micelle so they can be suspended or washed away. Contains xylitol, betaine, and glycerine to moisturize the skin as it cleans.
