Consumer Advice

Octyl gallate is a synthetic antioxidant, an ester of gallic acid and octanol, used to prevent fat oxidation. It is not authorised for food in the EU; China manages it under its additive system with usage limits. It poses no clear health risk at authorised levels, but it is used much less often than propyl gallate, so consumers rarely see it on labels.
