glycerol, glycerin, glycerine, or 1,2,3-propanetriol (prō`pāntrī'ŏl), CH₂OHCHOHCH₂OH, colorless, odorless, sweet-tasting, syrupy liquid. Glycerol is a trihydric alcohol alcohol, any of a class of organic compounds with the general formula R-OH, where R represents an alkyl group made up of carbon and hydrogen in various proportions and -OH represents one or more hydroxyl groups .

It is hygroscopic; i.e., it absorbs water from the air; this property makes it valuable as a moistener in cosmetics. Glycerol is present in the form of its esters ester, any one of a group of organic compounds with general formula RCO₂R′ (where R and R′ are alkyl groups or aryl groups) that are formed by the reaction between an alcohol and an acid.

It is obtained commercially as a byproduct when fats and oils are hydrolyzed to yield fatty acids or their metal salts (soaps). Glycerol is also synthesized on a commercial scale from propylene (obtained by cracking petroleum), since supplies of natural glycerol are inadequate. Glycerol can also be obtained during the fermentation of sugars if sodium bisulfite is added with the yeast. Glycerol is widely used as a solvent; as a sweetener; in the manufacture of dynamite, cosmetics, liquid soaps, candy, liqueurs, inks, and lubricants; to keep fabrics pliable; as a component of antifreeze mixtures; as a source of nutrients for fermentation cultures in the production of antibiotics antibiotic, any of a variety of substances, usually obtained from microorganisms, that inhibit the growth of or destroy certain other microorganisms.

glycerol

or glycerin

Clear, colourless, viscous, sweet-tasting liquid organic compound of the alcohol family, chemical formula HOCH₂CHOHCH₂OH. With three hydroxyl (−OH) groups, it can form three types of esters (monoglycerides, diglycerides, and triglycerides). Mono- and diglycerides are common food additives. Fats and oils are triglycerides; 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 cells, sperm, corneas, 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.

glycerol

a colourless or pale yellow odourless sweet-tasting syrupy liquid; 1,2,3-propanetriol: a by-product of soap manufacture, used as a solvent, antifreeze, plasticizer, and sweetener (E422). Formula: C₃H₈O₃

glycerol [′glis·ə‚rȯl]

(organic chemistry)

CH₂OHCHOHCH₂OH The simplest trihedric alcohol; when pure, it is a colorless, odorless, viscous liquid with a sweet taste; it is completely soluble in water and alcohol but only partially soluble in common solvents such as ether and ethyl acetate; used in manufacture of alkyd resins, explosives, antifreezes, medicines, inks, perfumes, cosmetics, soaps, and finishes. Also known as glycerin; Also known as glycerin; glycerine; glycyl alcohol. glycyl alcohol.
