Description

Ethoxyquin Hydrochloride is a stabilized salt form of the synthetic antioxidant ethoxyquin, offering enhanced handling and storage properties. This compound is valued for its potent ability to inhibit oxidative degradation, thereby preserving the quality and extending the shelf life of sensitive materials. It serves as a critical additive in the animal feed and pet food industries, as well as in the stabilization of various industrial products prone to oxidation.

Application

• Animal Feed Antioxidant: Primary application as a preservative in fish meal, poultry feed, and pet food to prevent rancidity and preserve nutritional value (e.g., vitamins A and E).
• Rubber & Polymer Stabilizer: Used as an antioxidant and antiozonant in the production of synthetic rubbers and certain polymers to prevent aging and cracking.
• Industrial Grease & Oil Additive: Incorporated into lubricants and industrial oils to inhibit oxidation and extend operational life.
• Pesticide Stabilizer: Acts as a stabilizer in certain pesticide formulations to prevent active ingredient degradation.
• Research & Development: Utilized in chemical research as a model antioxidant or intermediate for synthesizing other specialty chemicals.

Quality Control

Our Ethoxyquin Hydrochloride is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and related substances. While not a USP/NF or Ph. Eur. monograph item, quality is assured against rigorous in-house standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain maximum potency. Keep away from strong oxidizing agents.
