Product Description
Eastman Tenox™ TBHQ is highly refined tertiary-butylhydroquinone. Tenox™ TBHQ food-grade antioxidant was developed for use in stabilizing various oils, fats, foods, and cosmetics against oxidative deterioration, thus retarding development of rancidity in these products and extending shelf life. TBHQ is the most effective antioxidant for highly unsaturated vegetable oils and many edible animal fats. TBHQ shows no discoloration when used in the presence of iron and produces no discernible odor or flavor when added to various oils, fats, and foods. It has good solubility in food fats and oils and can be combined with other antioxidants such as Tenox™ BHA to produce highly effective antioxidant combinations.
