Description

α-Tocopherol Quinol is the reduced, hydroquinone form of Vitamin E (α-tocopherol), a potent lipid-soluble antioxidant. This compound is critical for applications requiring a highly effective oxygen scavenger to protect sensitive ingredients from oxidative degradation. It is essential for manufacturers in the pharmaceutical, nutraceutical, and high-end cosmetic industries seeking to enhance product stability and shelf life.

Application

• Pharmaceutical Antioxidant: Used as a stabilizing agent in injectable formulations, soft gel capsules, and topical ointments to prevent API oxidation.
• Nutraceutical & Dietary Supplements: A key active ingredient and stabilizer in high-potency Vitamin E supplements and combination antioxidant formulas.
• Cosmetic & Personal Care: Incorporated into anti-aging serums, creams, and sunscreens for its superior skin-protective antioxidant properties.
• Food & Beverage Fortification: Employed as a nutrient and preservative in functional foods and beverages, though specific food-grade compliance is required.
• Biochemical Research: Serves as a standard or reagent in studies of lipid peroxidation, oxidative stress, and antioxidant mechanisms.
• Industrial Stabilizer: Protects polymers, lubricants, and other industrial materials susceptible to oxidative breakdown.
