Safety Information
Glycerol tristearate Usage And Synthesis
  • DescriptionGlyceryl 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 Propertiesoff-white to cream powder
  • UsesPresent in animal and vegetable fats.
  • UsesIn textile sizes. Formerly in making candles.
  • Usestristearin is an emollient.
  • UsesGlyceryl 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.
  • DefinitionChEBI: A triglyceride that is glycerol in which all three hydroxy groups have been formally esterified with stearic acid.
  • Safety ProfileWhen heated to decomposition it emits acrid smoke and irritating fumes.
