Description

Butylated Hydroxytoluene CAS NO 128-37-0 is a highly effective synthetic phenolic antioxidant widely used to prevent oxidative degradation in a diverse range of materials. Its primary value lies in stabilizing products against deterioration caused by exposure to oxygen, thereby extending shelf life and maintaining performance integrity. This essential additive is critical for manufacturers in the food, polymer, cosmetic, and industrial lubricant sectors seeking reliable protection for their formulations.

Application

• Food & Beverage Preservation: Used as an antioxidant (E321) in fats, oils, cereals, and snack foods to prevent rancidity and extend shelf life.
• Polymer & Rubber Stabilization: Protects plastics, elastomers, and adhesives from thermal and oxidative degradation during processing and service life.
• Cosmetics & Personal Care: Incorporated into creams, lipsticks, and other formulations to stabilize oils and fats against oxidation.
• Fuel & Lubricant Additive: Serves as an antioxidant in jet fuels, gasoline, transformer oils, and industrial lubricants to inhibit gum formation.
• Pharmaceutical Excipient: Used in certain drug formulations and packaging materials to protect active ingredients from oxidative degradation.
• Animal Feed Antioxidant: Added to feed premixes and pet foods to preserve nutritional value and prevent spoilage of fat-soluble vitamins.

Quality Control

Our Butylated Hydroxytoluene is manufactured under a strict quality management system. We offer grades compliant with major pharmacopeial and food standards, including USP-NF, FCC, and Ph. Eur. Each batch undergoes rigorous analytical testing for identity, purity, and specified impurities. Certificates of Analysis (COA) documenting full compliance with agreed specifications are available for every shipment.

Storage

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