TBHQ Antioxidant — E319 / CAS 1948-33-0

Description

1. Product Overview
   TBHQ Antioxidant (E319, CAS 1948-33-0) is a high-performance, food-grade synthetic antioxidant widely used to stabilize fats and oils against oxidation and rancidity. It is primarily applied in the food processing industry to extend shelf life, preserve flavor integrity, and maintain product quality under heat and storage stress. With exceptional oxidative stability performance at low dosage levels, TBHQ delivers significant cost efficiency and functional reliability for large-scale industrial operations. Its strategic importance lies in enabling manufacturers to ensure long-term product freshness while minimizing waste and formulation costs in global supply chains.
2. Key Specifications & Technical Characteristics

3. Core Industrial Applications
   TBHQ is extensively used in edible oils, animal fats, fried food products, snack foods, and processed convenience foods to prevent oxidative degradation. It is also applied in biodiesel stabilization, cosmetic formulations, and select industrial lubricants where oxidation resistance is critical. Its superior thermal stability ensures performance during high-temperature processing such as frying and refining. Compared to natural antioxidants, TBHQ provides higher efficiency at lower dosage levels, delivering longer-lasting protection and improved cost-performance ratio for industrial-scale production.
