2,6-Di-tert-butyl-p-cresol is a widely used synthetic antioxidant with excellent anti-aging and anti-degradation properties. It can effectively inhibit the autoxidation process of organic materials caused by free radicals, and delay the deterioration, discoloration and performance decline of products due to oxidation.

It is widely applied in various industries for its stable antioxidant effect and good compatibility with most organic substrates. In the plastic and rubber industry, it is added to polymers to prevent thermal oxidative degradation during processing and storage, extending the service life of plastic and rubber products.

In the oil and fat industry, it is used as an antioxidant for edible oils, animal and vegetable fats, and various oil-based products, inhibiting rancidity caused by oxidation and maintaining the quality and flavor of oil products. It also serves as an antioxidant in the cosmetic and daily chemical industry, added to creams, lotions and other formulations to prevent the oxidation of oil components in products, prolonging the shelf life of cosmetics.
