| 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 | 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: 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 | Nonflammable | | Safety Profile | When heated to
decomposition it emits acrid smoke and
irritating fumes. |
