Glycerol tristearate Usage And Synthesis

Description

Glyceryl tristearate is prepared by reacting glycerin with stearic acid in the presence of a suitable catalyst such as aluminum oxide. It also occurs in many animal and vegetable fats such as tallow and cocoa butter. It is a white, microfine crystalline powder. It 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

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.

Uses

In textile sizes. Formerly in making candles.

Uses

tristearin is an emollient.

Definition

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

Flammability and Explosibility

Non flammable

Safety Profile

When heated to decomposition it emits acrid smoke and irritating fumes.
