TBHQ is regarded as the best antioxidant for protecting frying oils against oxidation. It provides good carry through protection similar to that of BHA and BHT. TBHQ widely used as antioxidants in cosmetics, food lipids and health products.

TBHQ also used in cereal-based snack foods, chewing gum, dehydrated broths, dehydrated meat, dehydrated potatoes, dehydrated soups, processed nuts, sauce, and seasoning and condiments.
