'''Glycerol''', or glycerin, is a clear, colourless, viscous, sweet-tasting liquid organic compound of the alcohol family, chemical formula HOCH2CHOHCH2OH. With three [[hydroxyl]] groups, it can form three types of [[ester]]s ([[monoglyceride]]s, [[diglyceride]]s, and [[triglyceride]]s). Mono- and [[diglyceride]]s are common food additives. Fats and oils are [[triglyceride]]s; their processing into [[soap]] was the chief source of glycerol until the mid-20th century, when industrial synthesis took over.

Glycerol has thousands of uses, including as an emulsifier, softening agent, plasticizer, and stabilizer in baked goods, ice cream, and tobacco; in skin lotions, mouthwashes, and cough medicines; as a protective medium for freezing [[red blood cell]]s, [[sperm]], [[cornea]]s, and other tissues; in printing inks and in the gums and resins in paints and coatings; in antifreeze mixtures; as a nutrient in [[fermentation]]; and as a raw material for [[nitroglycerin]].
