Active Pharmaceutical Ingredients
BHT (C₆H₅COOH) is a white, crystalline organic compound, the simplest aromatic carboxylic acid, known for its use as a food preservative (often as its salt, sodium benzoate) to inhibit yeast and mold, and in cosmetics, plastics, and medicine.
Yes. BHT is approved as an antioxidant in food products (like edible oils, fats, and processed foods) and pharmaceutical formulations (tablets, capsules, creams) to prevent oxidation and extend shelf life.
The recommended level varies by application and regulatory guidelines: typically 0.01–0.02% in food products and 0.01–0.1% in pharmaceutical or cosmetic formulations, depending on the matrix and required antioxidant protection.
BHT is more stable at high temperatures and provides longer-lasting protection than many natural antioxidants. It is cost-effective and widely used in industrial and food applications, while Vitamin E is milder and preferred in “natural” or clean-label formulations.
No. At recommended levels, BHT does not significantly alter the taste, odor, or color of food products, making it suitable for preserving flavor and appearance.
