Butylated hydroxytoluene (BHT) is a synthetic antioxidant that is used as a food preservative, antioxidant in cosmetics, and industrial additive. It is a white, crystalline solid that is soluble in fats and oils. BHT functions as a synthetic antioxidant by scavenging free radicals, thereby inhibiting oxidation reactions that can cause spoilage and degradation. While historically widely used, its safety and potential health effects have been a subject of ongoing research and debate.

BothPotential Benefits
Antioxidants neutralize harmful free radicals, preventing cellular damage and reducing oxidative stress, which can contribute to overall health and disease prevention. They work by donating electrons to stabilize free radicals and supporting antioxidant enzyme systems.
Possible Side Effects
BHT's potential to cause cancer is unclear, with conflicting evidence from animal and human studies. The IARC classifies BHT as not classifiable as to its carcinogenicity to humans, requiring further research.
