    • n Stearin stē"ȧ*rĭn (Physiol. Chem) One of the constituents of animal fats and also of some vegetable fats, as the butter of cacao. It is especially characterized by its solidity, so that when present in considerable quantity it materially increases the hardness, or raises the melting point, of the fat, as in mutton tallow. Chemically, it is a compound of glyceryl with three molecules of stearic acid, and hence is technically called tristearin, or glyceryl tristearate.

    • n stearin An ether or glyceride, C3H5O3(C18H35O2)3, formed by the combination of stearic acid and glycerin. When crystallized it forms white pearly scales, soft to the touch but not greasy, and odorless and tasteless when pure. It is insoluble in water, but soluble in hot alcohol and ether. When treated with superheated steam it is separated into stearic acid and glycerin, and when boiled with alkalis is saponified—that is, the stearic acid combines with the alkali, forming soap, and glycerin is separated. When melted it resembles wax. There are three stearins, which may all be regarded as derivatives of glycerin in which one, two, or three OH groups are replaced by the radical stearyl. Natural stearin is the tristearyl derivative of glycerin. It is the chief ingredient in suet, tallow, and the harder fats, and may be prepared by repeated solution in ether and crystallization. Candle-pitch, chandlers' gum, or residuary gum, used in the manufacture of roofing-cements, is a by-product of this manufacture.
    • n stearin A popular name for stearic acid as used in making candles.
