Stearin / ˈ s t ɪər ɪ n /, or tristearin, or glyceryl tristearate is an odourless, white powder. It is a triglyceride derived from three units of stearic acid . Most triglycerides are derived from at least two and more commonly three different fatty acids . [ 7 ]
Stearyl alcohol, or 1-octadecanol, is an organic compound classified as a saturated fatty alcohol with the formula CH 3 (CH 2) 16 CH 2 OH. It takes the form of white granules or flakes, which are insoluble in water. It has a wide range of uses as an ingredient in lubricants, resins, perfumes, and cosmetics.
The IUPAC name is octadecanoic acid. [9] It is a soft waxy solid with the formula CH 3 (CH 2) 16 CO 2 H. [9] The triglyceride derived from three molecules of stearic acid is called stearin. [9] Stearic acid is a prevalent fatty-acid in nature, found in many animal and vegetable fats, but is usually higher in animal fat than vegetable fat.

Palm stearin is the solid fraction of palm oil that is produced by partial crystallization at controlled temperature. [1] It is a stearin in the sense of stearins and oleins being the solid and liquid fractions respectively of fats and oils; not in the sense of glyceryl tristearate .
GMS is a food additive used as a thickening, emulsifying, anticaking, and preservative agent; an emulsifying agent for oils, waxes, and solvents; a protective coating for hygroscopic powders; a solidifier and control release agent in pharmaceuticals; and a resin lubricant.

Tallow is especially high in stearic acid content (as the triglyceride), whereas most fats only contain a few percent. The idealized equation for the formation of sodium stearate from stearin (the triglyceride of stearic acid) follows: (C 18 H 35 O 2) 3 C 3 H 5 + 3 NaOH → C 3 H 5 (OH) 3 + 3 C 18 H 35 O 2 Na
