بوتیل هیدروکسی تولوئن

Butylated Hydroxytoluene (BHT) is a lipophilic organic compound, a derivative of phenol, commonly used as an antioxidant. It prevents oxidation caused by free radicals in various substances such as food, cosmetics, and industrial products.
🏭⚗️ Production
BHT is produced by the alkylation of p-cresol with isobutylene.
🧪 Applications
It is widely used as a preservative in food products containing fats (like cereals, gum, and chips) to prevent discoloration and rancidity. BHT is also employed in cosmetics to stabilize formulations such as lipsticks and lotions, in pharmaceuticals to maintain drug stability, and in industrial products including rubber, plastics, oils, and fuels to prevent oxidative degradation.
⚠️ Safety
BHT is generally recognized as safe (GRAS) by the FDA for use in food and cosmetics when used within regulated limits. High oral doses have shown some adverse effects in animal studies, and certain countries restrict its use in food. In cosmetics, it is typically used at low concentrations and is considered safe without significant systemic toxicity.
