Glyceryl Tristearate is a natural product found in Lysiphlebia japonica, Aphis forbesi, and other organisms with data available.

Glyceryl Tristearate is a triglyceride that is glycerol in which all three hydroxy groups have been formally esterified with stearic acid. 
Glyceryl Tristearate has a role as a plant metabolite and a Caenorhabditis elegans metabolite. 
Glyceryl Tristearate derives from an octadecanoic acid.

Use:
-In textile sizes. Formerly in making candles.
-Soap; candies; adhesive pastes; metal polishes; water-proofing paper; leather stuffing; manufacture of stearic acid.
-Food additive (crystallization accelerator in chocolate).
-Textile sizing agent.
-Lubricant, eg, in cosmetics

Consumer Uses:
-Building/construction materials not covered elsewhere

Glyceryl Tristearate is an odourless, white powder. 
Glyceryl Tristearate 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.Like other triglycerides, stearin can crystallise in three polymorphs. For stearin, these melt at 54 (α-form), 65, and 72.5 °C (β-form).

Note that stearin is also used to mean the solid component of an oil or fat that can be separated into components that melt at higher (the stearin) and lower (the olein) temperatures. This is the usage meant in an example such as palm stearin.

Occurrence
Glyceryl Tristearate is obtained from animal fats created as a byproduct of processing beef. 
Glyceryl Tristearate can also be found in tropical plants such as palm. 
Glyceryl Tristearate can be partially purified by dry fractionation by pressing tallow or other fatty mixtures, leading to separation of the higher melting stearin-rich material from the liquid, which is typically enriched in fats derived from oleic acid. 
Glyceryl Tristearate can be obtained by interesterification, again exploiting its higher melting point which allows the higher melting tristearin to be removed from the equilibrated mixture. 
Stearin is a side product obtained during the extraction of cod liver oil removed during the chilling process at temperatures below −5 °C.

Uses
Glyceryl Tristearate is used as a hardening agent in the manufacture of candles and soap.
Glyceryl Tristearate is mixed with a sodium hydroxide solution in water, creating a reaction which gives glycerin and sodium stearate, the main ingredient in most soap:

C3H5(C18H35O2)3 + 3 NaOH → C3H5(OH)3 + 3 C18H35OONa
Glyceryl Tristearate is also added to aluminium flakes to help in the grinding process in making dark aluminium powder.

Glyceryl Tristearate is a chemical compound from the group of simple triglycerides. All three hydroxy groups of glycerol are esterified with stearic acid. 
Glyceryl Tristearate was shown that in tristearin treated human umbilical vein smooth muscle cells (HUVSMCs), the saturated fatty acid content was increased, and the compositions of polyunsaturated fatty acid (PUFA) and monounsaturated fatty acid were decreased significantly. 
Glyceryl Tristearate had significant promotion effects on the proliferation of HUVSMCs induced by oxidized‐LDL. 
Glyceryl Tristearate is a triacylglycerol commonly found in dietary fats. 
Glyceryl Tristearate increases serum cholesterol levels in rats. 
Glyceryl Tristearate is also used to form the lipid matrices of solid lipid nanoparticles. Formulations containing tristearin are used in cosmetic products to condition skin and as thickening agents.

Description
Glyceryl tristearate is prepared by reacting glycerin with stearic acid in the presence of a suitable catalyst such as aluminum oxide. 
Glyceryl tristearate also occurs in many animal and vegetable fats such as tallow and cocoa butter. 
Glyceryl tristearate is a white, microfine crystalline powder.
Glyceryl tristearate is soluble in hot alcohol, benzene and chloroform, very slightly soluble in cold alcohol, in ether and in petroleum ether, and insoluble in water.

Chemical Properties
off-white to cream powder

Uses
Present in animal and vegetable fats.

Uses
In textile sizes. Formerly in making candles.

Uses
tristearin is an emollient.

Uses
Glyceryl Tristearate is a formulation aid, lubricant, and release agent, prepared by reacting stearic acid with glycerol in the presence of a suitable catalyst. The additive is used as a crystallization accelerator in cocoa products; a formulation aid in confections; a formulation in fats and oils; and a winterization and fractionation aid in fat and oil processing.

Definition
ChEBI: A triglyceride that is glycerol in which all three hydroxy groups have been formally esterified with stearic acid.
