Glycerine is a colourless, odourless and vicious liquid, widely used in pharmaceutical and cosmetic industries. It has three hydroxyl groups that are required for its solubility in water and its hygroscopic nature. It is sweet in taste and has low toxicity. It is used as an element in cosmetics, hair products, medicines, and in several other applications.
