Product Description
Ascorbyl Palmitate is an ester formed from ascorbic acid (Vitamin C) and palmitic acid, a saturated fatty acid. This chemical modification makes Vitamin C fat-soluble (lipophilic), allowing for its incorporation into lipid-based formulations where ascorbic acid itself would not be stable or soluble. Ascorbyl Palmitate functions primarily as an antioxidant, helping to protect oils, fats, and other lipid-rich products from oxidative degradation, thereby extending their shelf life. It also contributes Vitamin C activity, though its primary use in food, cosmetics, and pharmaceuticals is often for its preservative and stabilizing antioxidant properties.

Ascorbyl Palmitate is valued for its antioxidant properties and its ability to function in lipid environments. Its main applications include:
- Food Industry: Widely used as an antioxidant (E304) to prevent rancidity in oils, fats, margarines, snack foods, and processed meats. It helps maintain product quality and extend shelf stability.
- Cosmetics and Personal Care: Incorporated into creams, lotions, sunscreens, and anti-aging products to protect lipid components from oxidation and to deliver antioxidant benefits to the skin. It can help stabilize other active ingredients.
- Pharmaceuticals: Used as an antioxidant excipient to protect active pharmaceutical ingredients (APIs) that are sensitive to oxidation in oil-based formulations, ointments, and supplements.
- Dietary Supplements: Included in oil-based Vitamin C supplements or multivitamin formulations where a fat-soluble form of Vitamin C is desired for better absorption or stability.
- Animal Feed: Used as a preservative and antioxidant to maintain the quality of animal feeds and pet foods.
As a supplier, providing high-quality Ascorbyl Palmitate (CAS 137-66-6) serves manufacturers in the food, cosmetic, pharmaceutical, and nutraceutical industries who require an effective fat-soluble antioxidant and Vitamin C source.
