Description

Ascorbyl Tocopheryl Maleate is a synergistic antioxidant compound formed by the esterification of ascorbic acid (Vitamin C) and tocopherol (Vitamin E) with maleic acid. This unique molecular structure provides enhanced stability and efficacy, making it a powerful free radical scavenger for protecting sensitive formulations. It is a critical ingredient for manufacturers in the cosmetic, personal care, and nutraceutical industries seeking to improve product shelf life and performance.

Application

• Cosmetic & Skincare Products: A key antioxidant in anti-aging serums, creams, lotions, and sun care products to protect skin from oxidative stress and UV-induced damage.
• Hair Care Formulations: Used in shampoos, conditioners, and treatments to shield hair from environmental damage and prevent color fading.
• Nutraceuticals & Dietary Supplements: Incorporated into softgel capsules and tablets for its combined Vitamin C and E antioxidant benefits.
• Pharmaceutical Topicals: Employed in ointments and gels to stabilize active pharmaceutical ingredients and protect the skin barrier.
• Functional Food Additives: Acts as a natural preservative and antioxidant in oil-based food products and supplements.
• Advanced Material Protection: Potential use in stabilizing polymers and sensitive materials against oxidative degradation.

Quality Control

Our Ascorbyl Tocopheryl Maleate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure it meets stringent specifications for cosmetic and nutraceutical applications. Certificates of Analysis (COA) documenting identity, purity, and related substances are provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is easily oxidized; for long-term storage, keeping the container under an inert atmosphere (e.g., nitrogen) is recommended to maintain optimal potency. Keep away from strong oxidizing agents.
