Propyl gallate is a compound with antioxidant properties that is used in the production of cosmetics, fats, oils, ethers, emulsions, and waxes.

A review of the use of propyl gallate and other compounds as antioxidants has been published. A discussion of in vivo toxicology studies of propyl gallate and other gallic acid esters has been reported.3 The synthesis of propyl gallate by transesterification of tannic acid with tannase from Aspergillus niger van Teighem has been described.

Propyl gallate has been used to probe the cyanideinsensitive alternative oxidase pathway of oxygen uptake in seeds of Orobanche aegyptiaca. A study of cultured lens epithelial cells treated with H2O2 has indicated that propyl gallate dismutates superoxide ion in a catalytic manner and thus mimics superoxide dismutase activity. Propyl gallate (1 mM) has been utilized to probe the activity of plastid oxidase from Arabidopsis thaliana as expressed in tobacco. A report has investigated the utility of propyl gallate with a gold cluster/fluorochrome-labeled antibody probe for immunofluorescence microscopy and immunoelectron microscopy
