Description

L-Ascorbyl Dipalmitate is a fat-soluble ester derivative of ascorbic acid (Vitamin C) and palmitic acid. This compound is highly valued as a potent antioxidant and emulsifier, offering superior stability in lipid-based systems compared to water-soluble Vitamin C. It is essential for manufacturers in the food, cosmetic, and nutraceutical industries seeking to enhance product shelf life and efficacy. Its primary function is to prevent oxidative rancidity and degradation in a wide range of formulations.

Application

• Food & Beverage Antioxidant: Used to prevent oxidation and extend the shelf life of oils, fats, margarine, and fat-containing foods.
• Cosmetic & Personal Care: A key active ingredient in anti-aging creams, serums, and lotions for its antioxidant properties and skin-brightening effects.
• Nutraceutical & Dietary Supplements: Incorporated into softgel capsules and oil-based supplement formulations as a stable source of Vitamin C.
• Pharmaceuticals: Used as an excipient and stabilizer in certain lipid-based drug delivery systems.
• Animal Feed Additive: Employed as a nutritional supplement and preservative in feed premixes.
• Color & Flavor Preservation: Helps maintain the natural color and flavor profile of processed food products.

Quality Control

We supply L-Ascorbyl Dipalmitate that meets stringent quality standards, including FCC (Food Chemicals Codex) and pharmaceutical-grade specifications where applicable. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles 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, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, open flames, and incompatible materials. Due to its light-sensitive nature, the container should be opaque or stored in darkness.
