BHT (Butylated Hydroxytoluene) is a synthetic, potent antioxidant, white crystalline oil-soluble powder that will delay the rancidity (auto-oxidation) of oils and fats (mainly containing polyunsaturated fatty acids) in food and personal care applications. It scavenges free oxygen radicals preventing oxidation inside the product (fat-stabilizer) and skin cell membranes and DNA after application.

In addition, Butylated Hydroxytoluene extends the shelf-life of oil-based formulations, preventing deterioration. It is used to help reduce the rate of rancidity in oils at the optimum level of antioxidant ranges from 0.02% to 0.1%.

BHT-treated moisturizing liquid oils, perfume, and flavors exhibit better shelf-life and fragrance stabilizing after the opening of the package. It rapidly dissolves in oils and poorly in water and can be used for essential oil caring soaps. Butylated Hydroxytoluene is widely used in decorative cosmetics, personal care products, and fragrances.

Combination with other ingredients

It improves the antioxidant properties of another ingredient, BHA, exhibiting good synergism and potentiation of action. When used with chelating agents di- or tetrasodium EDTA, BHT works better, preventing the tendency of products to become yellow.
