|Structure of propyl gallate|
Propyl gallate is less soluble in fats and oils than BHA and BHT and has significant solubility in water. The low oil solubility of propyl gallate makes this antioxidant difficult to incorporate into fats and oils and its solubility in water makes it more likely to complex with iron and iron salts, which causes dark discoloration in some applications.
