Glycerin is the earliest and widely used moisturizer in cosmetics. From the chemical formula, glycerol contains three OH molecules, which form hydrogen bonds with water molecules and bind water, and has strong hygroscopicity. It is a common ingredient in skin cleansers, creams and lotions. It can replenish moisture to the cuticle of the skin, regulate the physiological function of the skin, keep the skin healthy, and improve the sense of use.
In addition to being a moisturizing ingredient, another useful use of glycerin is as a solvent. Improves product ductility and increases skin absorption of other ingredients. Another important function of glycerin as a solvent is as the main component of mild facial cleansers. Glycerin has a certain fat solubility, can help clean the skin of excess oil; Glycerin, on the other hand, has a good water solubility and can be easily washed off, although it is not a surfactant, it can also act as a cleaning effect.
