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] Like other triglycerides, stearin can crystallise in three polymorphs.
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. Purified sodium stearate can be made by neutralizing stearic acid with sodium hydroxide. C 17 H 35 COOH+NaOH→C 17 H 35 COONa+H 2 O
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. It has a melting point of 69.4 °C (156.9 °F) °C and a pKa of 4.50. [11]
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 .

The company was founded in 1839 by Lars Johan Hierta, the same person who founded the Swedish daily newspaper Aftonbladet. [3] Originally the factory was located to Stockholm but in 1970 a new factory and a factory outlet was built in coastal town Oskarshamn, in the south-east of Sweden.
Magnesium stearate is often used as an anti-adherent [3] in the manufacture of medical tablets, capsules and powders. [4] In this regard, the substance is also useful because it has lubricating properties, preventing ingredients from sticking to manufacturing equipment during the compression of chemical powders into solid tablets; magnesium stearate is the most commonly used lubricant for ...
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.
