Lactose, milk sugar with the molecular formula C12H22O11, belongs to the group of disaccharides. Lactose consists of the two molecules D-galactose and D-glucose. Both molecules are connected to each other by a β-1,4-glycosidic bond. Lactose is a crystalline or granular powder with a slightly sweet taste. The substance is used in cosmetic formulations. It is easily soluble in water, poorly soluble in ethanol.

The disaccharide acts as a humectant (preserves the skin moisture) and skin care product.
