Glycerine (CAS 56-81-5, USP grade) is very common materials used in medicine, cosmetic, food and other industrial production.
Glycerine is used in medical and pharmaceutical and personal care preparations, mainly as a means of improving smoothness, providing lubrication and as a humectants. And the Glycerin moisturizing effect is more significant than other polyol moisturizing agents, It has the function of preventing chapped cosmetics, it is widely used in various cosmetics. Adsorption of one gram of glycerol 0.6 g of water under high humidity environment is the most preferable.
