[Gk. glykys, sweet.] A colorless, inodorous, syrupy liquid, having a very sweet taste, soluble in water and alcohol, but insoluble in ether and chloroform. It is obtained from fats. It has numerous uses both in the arts and in medicine. It is used in calico-printing, in perfumery, in leather-making, and in the manufacture of copying ink. When added to water, it lowers the freezing point, and has in this way been serviceable in preventing the freezing of the water in gas-meters. In medicine it is applied externally for softening the skin, and it may be used as a substitute for cod-liver oil. Dissolved in a mixture of nitric and sulphuric acids, it yields the powerful explosive called nitro-gly-cerine (q.v.)
