Introduction
A pungent odor with a specific phenolic odor. Leather aroma, insoluble in water, soluble in oil, ethanol, glycerin, propylene glycol. It is quite stable to heat and is not easy to destroy under weakly alkaline conditions.
Application
Butylated hydroxyanisole (BHA, CAS 25013-16-5) is a synthetic phenolic antioxidant widely used to prevent oxidative rancidity in fats, oils, and fat-containing foods. It is approved as a food additive (E320) in edible oils, snacks, meats, baked goods, cereals, and chewing gum, extending shelf life by scavenging free radicals. In animal feed, BHA protects vitamins and fatty acids from degradation. In cosmetics and personal care, it serves as a preservative and stabilizer for lipsticks, lotions, and creams. Industrial applications include rubber and plastic stabilization, fuel additives, and lubricants. Xinchem offers custom synthesis, custom chemical synthesis, and contract manufacturing of high-purity BHA with flexible scaling from R&D to commercial tons.
