McDonald’s frying oil contains a small amount of an additive called dimethlypolysiloxane, which helps prevent oil from foaming and spattering in our restaurants.
All of the ingredients we use, including dimethylpolysiloxane, meet recognized food quality and safety standards. Because dimethylpolysiloxane is used in some non-food products, like putty, caulks or cosmetics, there have been individuals who have erroneously claimed that these items are also in our food.
We recognize the difference between using ingredients in food versus using a variation of those ingredients for non-food purposes can be confusing. We also realize that sometimes the scientific name for an ingredient may sound scary. For example, the salt you use to de-ice a driveway is a variation of the salt you use in the kitchen, however they are both sodium chloride.
