Widely used as an antioxidant in industrial applications, it prevents oxidative degradation of materials sensitive to heat and air exposure. In the plastics and rubber industries, it stabilizes polymers during processing and extends product life by inhibiting polymerization and chain reactions caused by free radicals.

Commonly added to lubricating oils, fuels, and hydraulic fluids to protect against oxidation, which can lead to sludge formation, viscosity changes, and equipment corrosion. Its effectiveness at high temperatures makes it suitable for use in engine oils and industrial greases.

In the food industry, it preserves fats, oils, and fat-containing foods by delaying rancidity, thus maintaining flavor and shelf life. Also found in cosmetics and personal care products such as lipsticks, creams, and lotions, where it protects ingredients from air and light-induced spoilage.

Used in pharmaceutical formulations to maintain active ingredient potency by preventing oxidative breakdown during storage. Its low toxicity and high stability under processing conditions make it a preferred choice across multiple sectors requiring long-term oxidative protection.
