Octyl Gallate or E311 is a synthetic antioxidant that presents itself as a white or slightly yellow crystalline powder and is used to prevent spoilage in processed foods, supplements, and medicine, in particular by averting oxidation of fats and oils.
Propyl Gallate or E310 is a synthetic compound (white or pale-yellow crystalline powder) typically used as an antioxidant to prevent spoilage and off-flavors of various foods (especially the fats and oils used within them).
Delta-Tocopherol (E309) is another synthetic Tocopherol (one of vitamin E forms) along with Alpha-Tocopherol (E307) and Gamma-Tocopherol (E308) that is used as an additive in various products.
Gamma-Tocopherol or E308 is one of four different vitamin E forms that can be made synthetically (dl- form) and are commonly used as additives.
Alpha-Tocopherol or E307 is the synthetic vitamin E that is used as an additive. Meaning, it is the “dl-” form of the vitamin (synthetic).
