Propyl gallate Usage And Synthesis
Chemical Properties white to light beige crystalline powder
Chemical Properties Propyl gallate is a white, odorless or almost odorless crystalline powder, with a bitter astringent taste that is not normally noticeable at the concentrations employed as an antioxidant.
Uses Propyl Gallate is an antioxidant that is the n-propylester of 3,4,5-tri- hydroxybenzoic acid. natural occurrence of propyl gallate has not been reported. it is commercially prepared by esterification of gallic acid with propyl alcohol followed by distillation to remove excess alcohol.
Uses propyl gallate is an anti-oxidant with preservative properties.
