Ascorbyl Palmitate(CAS No.: 137-66-6)

Ascorbyl Palmitate(CAS No.: 137-66-6), also known as Vitamin C Palmitate or Fat-soluble Vitamin C. It is a far superior form of vitamin C supplementation compared to pure vitamin C itself, boasting stronger antioxidant activity as well as heat resistance and high stability. It is a safe and highly effective fat-soluble antioxidant, and a raw material for health products, cosmetics, as well as a pharmaceutical excipient.

Preparation Method: Enzymatic Synthesis
Use lipase as a biological catalyst to facilitate the esterification reaction between ascorbic acid and palmitic acid, followed by separation and purification to obtain high-purity ascorbyl palmitate.

Safe & Highly Effective
Ascorbyl Palmitate has been rated by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) as a non-toxic, highly effective and nutritive food additive. It is listed as Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration (FDA), and recognized as a safe and compliant additive by the National Health Commission of the People’s Republic of China (NHC), the European Food Safety Authority (EFSA) and the Ministry of Health, Labour and Welfare of Japan (MHLW). It is also a recommended oil-based food stabilizer by the Food and Agriculture Organization of the United Nations (FAO).

In addition to its outstanding antioxidant efficacy and stability, AP also delivers nutritional benefits including free radical scavenging, cellular oxidation prevention, promotion of collagen synthesis and iron absorption. It is truly a “next-generation nutritive antioxidant” in the true sense.
Listed as a Pharmaceutical Excipient in Multiple Countries
It is included as a pharmaceutical excipient in the United States Pharmacopeia (USP) and the British Pharmacopoeia (BP).
Preferred Antioxidant for Infant Food
It is a globally approved antioxidant for use in infant formula (milk powder, complementary food).

Food Application

Ascorbyl palmitate ranks among the most high-performance fat-soluble antioxidants. It effectively inhibits lipid oxidation and exhibits a far better performance than BHA and BHT in preventing oxidative deterioration. It has a synergistic effect and delivers enhanced efficacy when used in combination with other antioxidants such as vitamin E.

① Antioxidant

② Color Fixative

Cosmetics Application

Ascorbyl palmitate (AP) is currently incorporated into approximately 22,000 cosmetic formulations worldwide. Structurally, AP retains the reductive groups of vitamin C;

① Skin Whitening
② Antioxidation
③ Anti-inflammation
④ Ameliorates the inflammatory microenvironment
⑤ Inhibits hyaluronidase activity

Nutrition Supplements Application

① Vitamin C Nutrient Fortification
Ascorbyl palmitate is a fat-soluble form of vitamin C, which is more readily utilized by the human body than other vitamin C variants.
② Antioxidant Supplementation
It is truly a “next-generation nutritive antioxidant” in the true sense.
③ Formula Stabilization & Synergistic Enhancement
