Application
2,6 Di Tert Butyl 4 Methylphenol, commonly known as BHT, is one of the most widely used phenolic antioxidants across multiple industries.
In the polymer and plastics industry, it serves as a primary antioxidant for polyolefins, polystyrene, polyurethanes, and elastomers, preventing thermal and oxidative degradation during processing and end use. In rubber manufacturing, it protects natural and synthetic rubber from oxidation and ozone cracking. In the petroleum industry, BHT is used as a fuel additive in gasoline, jet fuels, hydraulic fluids, and turbine and gear oils to prevent peroxide formation and gumming.
In the food industry, BHT is approved as a food additive (E321) to prevent rancidity in fats, oils, and fat containing foods. European and US regulations allow small amounts to be used as a food additive. In pharmaceutical and cosmetic applications, it serves as an antioxidant in gels, creams, liquids, gelatin capsules, tablets, vitamins, and personal care products. It is also used as a stabilizer in cosmetics and toiletries. In research applications, BHT is utilized as a free radical scavenger to inhibit lipid peroxidation and as a ferroptosis inhibitor in biological studies.
