    Description
    Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its Antioxidants properties. European and U.S. regulations allow small amounts to be used as a food additive. In addition to this use, BHT is widely used to prevent oxidation in fluids (e.g. fuel, oil) and other materials where free radicals must be controlled.

    Application
    2,6-Di-tert-butyl-4-methylphenol, commonly known as Butylated Hydroxytoluene (BHT), serves primarily as a synthetic antioxidant and preservative in various applications. Its main purpose is to delay or prevent the oxidative rancidity of fats and oils, thus preserving the quality and shelf life of food products. BHT achieves this by scavenging radicals and inhibiting lipid peroxidation, making it particularly useful in foods, cosmetics, and pharmaceuticals where the maintenance of product stability and potency is crucial. Additionally, it aids in preventing the loss of activity of oil-soluble vitamins and is employed in both natural and synthetic rubber applications to enhance color stability. Though BHT is less stable at high temperatures compared to similar antioxidants, it remains a popular choice for its efficacy at typical usage levels. Beyond its preservative qualities, BHT also exhibits antiviral properties, having been used in the treatment of conditions like herpes simplex labialis. Overall, its low toxicity and effectiveness contribute to its widespread use across consumer products.
