Uses: Octyl Gallate is used in oils, margarine, lard and salad dressings, cereals, snack foods, dairy produce, sometimes used in packaging. It is used as an antioxidant in food, often with BHT E321 and BHA E320, although it has limited use as it is unstable at high temperatures.
May cause gastric or skin irritation. Gallates are not permitted in foods for infants and small children because of their known tendency to cause the blood disorder, methemoglobinemia.
It is suspected as being listed as additives that act as "xenoestrogens" - substances with oestrogen-like effects. Xenoestrogens have been linked to a range of human health effects, including reduced sperm counts in men and increased risk of breast cancer in women. See E586.
Description: Octyl Gallate is used to prevent oily substances from going rancid. It is derived from nutgalls which are formed by the Gall wasp laying her eggs inside the branches of oak trees.
The resulting galls are said to be anti-viral and anti-fungicidal, and Gallic Acid is extracted, however they are then mixed with propanol which is alcohol based and a possible irritant.
The resulting mixture can then become a metabolised form of Propionate which can also be toxic
