Description and Uses

Glycerol is a colorless, viscous, hygroscopic, sweet-tasting trihydric alcohol. It is also called glycerin or glycerine, with the term glycerol being preferred as the pure chemical form and the term glycerin(e) being primarily used when the compound is used commercially in various grades.

Glycerol's properties make it useful for numerous applications. The three hydroxyl groups in glycerol allow extensive hydrogen bonding that gives glycerol its characteristic syrupy viscous texture and hygroscopic character. Approximately 40% of glycerol's use is for personal care products such as cosmetics, soaps, shampoos, lotions, mouthwash, and toothpaste. Glycerol's hygroscopic properties make it a good moisturizer in skin products. Another 25% of glycerol's annual production is used in food production. In the food industry glycerol is used as a moistening agent, as a solvent for food coloring and syrups, to prevent crystallization of sugar in candies and icings, as a preservative, and as a sweetening agent. Approximately 10% of glycerol's use goes into tobacco processing, where it is sprayed on tobacco leaves before they are shredded to serve as a moistening agent. Glycerol has the added benefit of imparting a sweet taste to chewing tobacco. The remaining 25% of glycerol's use is distributed among various industrial uses. It is used in cough syrups and elixir medicines. In industry, glycerol is found in lubricants, plasticizers, adhesives, antifreezes, resins, and insulating foams. At one time it was used almost exclusively in its nitrated form as an explosive (see Nitroglycerin), which today accounts for about 3% of its use.
