Product Introduction:
Ascorbyl Palmitate is a fat-soluble derivative of vitamin C (L-ascorbic acid) and palmitic acid. It is a white or yellow-white powder with a slight citrus smell, a melting point between 107°C and 117°C, and a specific rotation of +21° to +26°. Ascorbyl Palmitate has good antioxidant properties and is more stable than vitamin C. It can withstand high temperatures and is not easily oxidized. It overcomes the shortcomings of vitamin C that it is afraid of heat, light, and moisture, so it has a wide range of application value in many fields.
In the food field, Ascorbyl Palmitate is widely used as an antioxidant and nutritional enhancer. It can be used in edible oils, oil-containing foods, instant noodles, bread and other foods. It can effectively prevent oil oxidation and rancidity and extend the shelf life of food. At the same time, it can also provide the nutritional function of vitamin C to the human body. In addition, Ascorbyl Palmitate is the only antioxidant allowed to be added to baby food. It can be used in infant formula and complementary foods to meet the needs of infants for vitamin C and promote their growth and development.
In the field of medicine and health products, Ascorbyl Palmitate also has important application value. Studies have shown that it can strongly inhibit the DNA synthesis of cancer cells and decompose the cell membrane phospholipids of cancer cells, and has a certain anti-cancer effect
In the field of cosmetics, Ascorbyl Palmitate is widely used in various skin care products and cosmetics due to its antioxidant and stability. It can effectively resist the damage of free radicals to the skin, delay skin aging, and enhance the stability and shelf life of cosmetics. In addition, it also has a certain whitening effect, can inhibit the formation of melanin, and improve skin color.
The production processes of Ascorbyl Palmitate mainly include acyl chloride method, sulfuric acid method and lipase method. Among them, the acyl chloride method is highly corrosive, the sulfuric acid method has a long reaction time and serious pollution, and the lipase method is green and environmentally friendly, but the technology is not yet mature. With the continuous advancement of science and technology, it is expected to develop more efficient and environmentally friendly production processes in the future to meet the growing market demand for Ascorbyl Palmitate.

Ascorbyl Palmitate has quickly become an indispensable antioxidant solution in the food industry. Used on easily oxidized systems such as vegetable oils and animal fats, Ascorbyl Palmitate can increase shelf life by 30-50% by directly eliminating free radicals and blocking peroxide formation. Furthermore, Ascorbyl Palmitate’s heat resistance advantage can effectively prevent oil degradation or food spoilage during high-temperature processing situations like frying food products like instant noodles and baked products.
The dairy industry takes advantage of Ascorbyl Palmitate’s fat-soluble properties by adding it to products containing fat such as milk powder and cheese, to both protect from oxidation while providing nutritional enhancement benefits from vitamin C. Furthermore, Ascorbyl Palmitate excels at blocking the formation of nitrosamines; this allows it to be utilized effectively during meat processing to minimize carcinogenic risk while improving color stability of products.
Ascorbyl Palmitate has become an invaluable ingredient for use in cosmetics industry products, from basic antioxidants to multifunctional composites. Being fat soluble, Ascorbyl Palmitate penetrates deep into skin layers quickly, effectively stimulating collagen synthesis while simultaneously inhibiting tyrosinase activity in dermis tissue. While its direct bleaching effect may be less dramatic than that of vitamin C itself, Ascorbyl Palmitate can still significantly reduce photoaging damage while improving skin elasticity indicators by eliminating ultraviolet-induced free radicals from skin layers deep within.
Formulator practice shows Ascorbyl Palmitate forming a synergistic system with vitamin E: after vitamin E captures free radicals and releases tocopherol free radicals, Ascorbyl Palmitate acts to reduce and regenerate them through its circulation mechanism – increasing antioxidant efficacy by up to three-five times while simultaneously decreasing total ingredients added. This synergy is especially significant in high-end anti-aging products where this can both extend active ingredient effectiveness while meeting streamlining trends for cosmetic formulas.
Medicine and health care increasingly place emphasis on increasing the physiological activity value of Ascorbyl Palmitate. Used as a vitamin C precursor, Ascorbyl Palmitate helps ensure stable ascorbic acid concentration in the body through sustained release, making it particularly helpful for cardiovascular and cerebrovascular diseases patients requiring long-term vitamin C supplementation.
Studies have demonstrated the ability of Ascorbyl Palmitate to not only promote cholesterol metabolism and lower the risk of low-density lipoprotein oxidation, but also boost immune cell activity – characteristics which make it widely used in functional foods and dietary supplements. More cutting-edge research suggests it has an inhibitory effect on DNA synthesis in certain cancer cells – opening a possible new avenue for adjuvant tumor treatment; although its mechanism requires further clinical validation.
From the perspective of product competitiveness, the core advantage of Ascorbyl Palmitate is first reflected in regulatory compatibility. Compared with the use restrictions of synthetic antioxidants such as TBHQ and BHT in the EU, Japan and other places, Ascorbyl Palmitate has obtained access to major global markets due to its natural origin characteristics, which is of strategic significance to export-oriented manufacturers. In sensitive areas such as infant food and pharmaceutical preparations, it has become one of the few compliant antioxidant options, and this irreplaceability has strengthened its market position.
In terms of technical performance, Ascorbyl Palmitate has an oxidation potential of +0.28V and an efficiency of scavenging DPPH free radicals of more than 90%, which is at the leading level among similar natural antioxidants. Its affinity with the phospholipid bilayer is 1.3 times that of vitamin E. This molecular characteristic not only improves its distribution uniformity in the lipid system, but also enhances the cell membrane protection effect.
From the perspective of economic benefits, although the unit cost of Ascorbyl Palmitate is higher than that of synthetic antioxidants such as BHA, its use concentration is only 1/5-1/10 of that of traditional products to achieve the same antioxidant effect. Adding 0.02% Ascorbyl Palmitate to the oil system can extend the shelf life by more than 30 days. This high cost-effectiveness makes it still competitive in cost-sensitive applications. The stability parameters further highlight its long-term value: in the 40℃ accelerated test, its activity retention rate is still more than 85% after 6 months, which is much better than the 30% retention rate of the prototype vitamin C, which directly reduces the quality loss of the product during storage and transportation.
From the perspective of technological development, the derivatization research of Ascorbyl Palmitate continues to expand its application boundaries. New derivatives such as tetraisopalmitate developed through molecular modification have increased the transdermal absorption rate to 2-3 times that of the prototype VC while maintaining the advantage of fat solubility. This technological innovation has given Ascorbyl Palmitate a new lease of life in transdermal drug delivery systems and high-end skin care products. These technological advances have paved the way for it to enter the pharmaceutical raw material market.
Overall, Ascorbyl Palmitate has become a key functional raw material connecting the three major industries of food, cosmetics, and medicine with its unique physicochemical properties, wide application adaptability, and excellent safety performance. With the growth of consumer demand for natural ingredients and the tightening of regulations on synthetic additives, the technical value and market space of Ascorbyl Palmitate and its derivatives will continue to be released, playing an increasingly important role in the upgrading of the health industry.
