Description and Uses
During the 1940s, propyl gallate and several other alkyl gallates were allowed for use in foods in a number of countries. Since gallic acid contains three phenolic hydroxyl groups, it is a rather potent antioxidant; however, the propyl ester has a significant degree of water solubility. As a consequence, propyl gallate tends to partition into any water phase which may be present and to complex with iron salts to give bluish black colors. Also, its relatively poor resistance to heat degradation makes it ineffective for baking and frying applications. The higher alkyl gallates (butyl and octyl) are more fat soluble.
Used in treatment of alcohol dependence.
