Glycerol /ËÉ¡lÉªsÉrÉl/ (also called glycerine or glycerin; see spelling differences) is a simple polyol (sugar alcohol) compound. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Glycerol has three hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature. The glycerol backbone is central to all lipids known as triglycerides.
Most glycerin is made as a by-product of the manufacture of soap. In this process, either animal fat or vegetable oil can be used. It is heated with a strong alkali, usually caustic soda (sodium hydroxide), which produces soap and a solution of glycerin in water.ost glycerin is made as a by-product of the manufacture of soap.
