BHT (Butylated Hydroxytoluene) FCC is a food grade antioxidant used to delay the oxidative rancidity of oils and fats and thereby extend the shelf life of both food and cosmetics. When used in soapmaking, BHT is best used in combination with tetrasodium EDTA (which is added to the water). In perfumery and cosmetic use, BHT is added to the oil phase of cosmetic formulations or the alcohol for perfumes. Typical usage rates are 0.05 – 0.1%. To extend the shelf life of oils, FDA approves of adding 1/4 tsp to 1 gallon of oil. Also excellent for long storage of gasoline in motors. BHT is classified as GRAS (generally regarded as safe) by the US FDA. It is generally recognized as safe for use in food when the total content of antioxidants does not exceed 0.02% of the fat or oil content of food.
