Tert-Butylhydroquinone, commonly abbreviated as TBHQ, is a highly effective synthetic antioxidant widely used in various fields. It is known for its strong antioxidant capacity, good stability and low toxicity when used within the specified range.

It has excellent resistance to high temperatures and light, and is not easy to decompose under normal processing and storage conditions. It is slightly soluble in water but easily soluble in edible oils, fats, ethanol and other organic solvents, with a slight special odor.

In the food industry, TBHQ is mainly used as an antioxidant to delay the oxidation and rancidity of oil-containing and fatty foods. It can effectively inhibit the formation of harmful substances such as peroxides during food storage, thereby extending the shelf life of food.

It is widely applied in edible oils, fried foods, baked goods, dried meat products, snacks, instant foods and other products. Its usage is strictly controlled by relevant national standards to ensure food safety.

Compared with other antioxidants, TBHQ has the advantages of fast antioxidant speed and strong effect. It can also synergize with other antioxidants to improve the overall anti-oxidation effect and reduce the usage of single antioxidants.

In addition to the food industry, TBHQ is also used in cosmetics, pharmaceuticals and industrial fields. In cosmetics, it acts as an antioxidant to prevent the oxidation of active ingredients and extend the product's validity period.
