Description

Ethoxyquin is a synthetic antioxidant widely recognized for its efficacy in preventing oxidative degradation. Its primary commercial value lies in its ability to preserve the quality and shelf life of sensitive materials, particularly in animal feed and pet food. This product is essential for manufacturers in the feed, aquaculture, and food processing industries seeking to maintain nutritional value and prevent spoilage.

Application

• Primary antioxidant in animal feed and pet food to preserve fats, oils, and fat-soluble vitamins (e.g., Vitamin A, E).
• Preservative in fish meal and fish oil for aquaculture and animal nutrition to prevent rancidity.
• Stabilizer for spices and paprika oleoresins to maintain color and flavor.
• Antioxidant in rubber and polymer production to inhibit degradation during processing and storage.
• Additive in certain pesticide formulations to improve stability.
• Research and development applications in chemical synthesis and material science.

Quality Control

Our Ethoxyquin is produced under a stringent quality management system. Each batch is tested to ensure it meets defined specifications for identity, purity, and performance. While commonly supplied in technical or feed-grade quality, production can be aligned with relevant industry practices. 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). Due to its nature as an easily oxidized substance, prolonged exposure to air should be minimized. Keep away from strong oxidizing agents.
