STEARATE
Ste"a*rate, n. (Chem.)
Defn: A salt of stearic acid; as, ordinary soap consists largely of sodium or potassium stearates.
STEARIC
Ste*ar"ic, a. Etym: [Cf. F. stéarique.] (Physiol. Chem.)
Defn: Pertaining to, or obtained from, stearin or tallow; resembling tallow. Stearic acid (Chem.), a monobasic fatty acid, obtained in the form of white crystalline scales, soluble in alcohol and ether. It melts to an oily liquid at 69°C.C18H36O2, CH3.(CH2)16.COOH; sodium stearate, with sodium palmitate, is the main component of ordinary bar soaps (Such as Ivory soap).
STEARIN
Ste"a*rin, n. Etym: [Gr. stéarine.] (Physiol. Chem.)
Defn: 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.
STEAROLIC
Ste`a*rol"ic, a. Etym: [Stearic + oleic + -ic.] (Chem.)
Defn: Of, pertaining to, or designating, an acid of the acetylene series, isologous with stearis acid, and obtained, as a white crystalline substance, from oleïc acid.
STEARONE
Ste"a*rone, n. (Chem.)
Defn: The ketone of stearic acid, obtained as a white crystalline substance, (C17H35)2.CO, by the distillation of calcium stearate.
