    • n Glycerin (Chem) An oily, viscous liquid, C3H5(OH)3, colorless and odorless, and with a hot, sweetish taste, existing in the natural fats and oils as the base, combined with various acids, as oleic, margaric, stearic, and palmitic. It may be obtained by saponification of fats and oils. It is a triatomic alcohol, and hence is also called glycerol. See Note under Gelatin.☞ It is obtained from fats by saponification, or, on a large scale, by the action of superheated steam. It is used as an ointment, as a solvent and vehicle for medicines, and as an adulterant in wine, beer, etc.

Century Dictionary and Cyclopedia
    • n glycerin A transparent, colorless, hygroscopic liquid (C3H5(OH)3), with a sweet taste and syrupy consistence. It occurs in natural fats combined with fatty acids, and is obtained from them by saponification with alkalis or by the action of superheated steam. It is a triatomic alcohol, and dissolves the alkalis, alkaline earths, and some metallic oxids, forming compounds analogous to the alcoholates. It is used in medicine as an emollient and protective dressing, with which, from its consistence and solvent properties, many substances can be incorporated; it absorbs watery discharges, and has some astringent action. The name is also applied to mixtures of glycerin with various substances, whether involving solution or not: as, glycerin of gallic acid; glycerin of starch. It is used in the arts for a great variety of purposes: for example, in soaps and cosmetics, for preserving animal and vegetable substances, in paper-making, and in the manufacture of nitroglycerin and dynamite. Also called glycerol, glycerole, glycerina, and glycerinum.
    • n glycerin Formerly a general designation for compounds similar to glycerol in that they contain three hydroxyl groups.
