Butylated hydroxytoluene (BHT), also known as dibutyl hydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties. BHT is also used to prevent peroxide formation in diethyl ether and other laboratory chemicals.
Butylated hydroxytoluene, a potent synthetic antioxidant that also has health concerns when consumed orally. The amount of BHT uses in cosmetic products is typically 0.01-0.1%, and does not pose a risk to the skin, nor does it penetrate skin far enough to be absorbed into the bloodstream.
Butylated hydroxytoluene (BHT), also known as dibutyl hydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties.BHT is widely used to prevent free radical-mediated oxidation in fluids (e.g. fuels, oils) and other materials, and the regulations overseen by the U.S. F.D.A.—which considers BHT to be "generally recognized as safe"—allow small amounts to be added to foods. Despite this, and the earlier determination by the National Cancer Institute that BHT was noncarcinogenic in an animal model, societal concerns over its broad use have been expressed. BHT has also been postulated as an antiviral drug.
Antioxidant:- BHT is also used as an antioxidant in products such as metalworking fluids, cosmetics, pharmaceuticals, rubber, transformer oils, and embalming fluid. In the petroleum industry, where BHT is known as the fuel additive AO-29, it is used in hydraulic fluids, turbine and gear oils, and jet fuels. BHT is also used to prevent peroxide formation in organic ethers and other solvents and laboratory chemicals. It is added to certain monomers as a polymerization inhibitor to facilitate their safe storage. Some additive products contain BHT as their primary ingredient, while others contain the chemical merely as a component of their formulation, sometimes alongside butylated hydroxyanisole (BHA).
Food Additive:- BHT is primarily used as an antioxidant food additive. it is classified as generally recognized as safe (GRAS) based on a National Cancer Institute study from 1979 in rats and mice. It is approved for use in the U.S. by the Food and Drug Administration: For example, allows BHT up to 0.0033% by weight in "enriched rice", while 9 allows up to 0.01% in poultry "by fat content". It is permitted in the European Union under E321.
BHT is used as a preservative ingredient in some foods. With this usage BHT maintains freshness or prevents spoilage; it may be used to decrease the rate at which the texture, color, or flavor of food changes.
Some food companies have voluntarily eliminated BHT from their products or have announced that they were going to phase it out.
