Description

tert-Butylhydroquinone (TBHQ) is a highly effective synthetic phenolic antioxidant widely used to prevent rancidity and oxidative degradation in fats and oils. Its primary commercial value lies in extending the shelf life and maintaining the quality of perishable lipid-based products. This compound is essential for manufacturers in the food, cosmetic, and polymer industries who require a reliable and approved antioxidant for their formulations.

Application

• Food Industry Antioxidant: Primary application for stabilizing edible oils, fats, margarine, and fried snacks to prevent rancidity and off-flavors.
• Cosmetic & Personal Care: Used in creams, lotions, and lipsticks to protect oil-based ingredients from oxidation and spoilage.
• Polymer & Rubber Stabilizer: Acts as an antioxidant in the production of synthetic rubbers, adhesives, and certain plastics to inhibit degradation.
• Biofuel & Industrial Oil Additive: Employed to improve the oxidative stability of biodiesel and various industrial lubricants.
• Pharmaceutical Intermediate: Serves as a chemical building block or stabilizer in certain pharmaceutical synthesis processes.
• Animal Feed Preservative: Used in small quantities to protect fats and fat-soluble vitamins in feed products.

Quality Control

Our tert-Butylhydroquinone is produced under strict quality management systems. We offer grades compliant with FCC (Food Chemicals Codex) and food-grade specifications for global applications. Every batch undergoes rigorous analytical testing to ensure identity, purity, and safety. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage of bulk quantities, an inert atmosphere (e.g., nitrogen) is recommended. Keep away from strong oxidizing agents.
