Ascorbyl Palmitate Chemical Properties,Uses,Production

Description

Ascorbyl palmitate is a lipophilic derivative of ascorbic acid with antioxidant and antiproliferative activities. It scavenges hydroxyl radicals in cell-free assays. Ascorbyl palmitate (0.01%) reduces the rate of autoxidation of soybean, safflower, sunflower, peanut, and corn oil. It inhibits increases in epidermal ornithine decarboxylase activity and DNA synthesis induced by phorbol 12-myristate 13-acetate (TPA; ) in mice in a concentration-dependent manner when applied topically. Ascorbyl palmitate (0.8 and 4 μmol per 200 μl of acetone, applied topically) reduces the number of tumors per mouse and the percentage of mice with tumors in a mouse skin two-stage model of tumor formation initiated and promoted by 7,12-dimethylbenz[a]anthracene (DMBA) and TPA, respectively. Formulations containing ascorbyl palmitate have been used as antioxidants and preservatives in foods, pharmaceuticals, and cosmetics.

Chemical Properties

Ascorbyl palmitate is a white or yellowish-white solid with a soapy taste and a citrus-like odor. It is very slightly soluble in water but freely soluble in alcohol, animal oil, and vegetable oil. It melts at 107° to 117°C (around 234°F). Ascorbyl palmitate prevents oxidative rancidity development by quenching singlet oxygen. The ascorbic acid part of the molecule donates hydrogen (a reducing agent). This phenomenon is also called "oxygen scavenging".

About China Ascorbyl Palmitate, Vatinmin C derivative, Vitamin C Palmitate

China is a leading producer of Vitamin C Ascorbyl Palmitate, a high-quality derivative of Vitamin C renowned for its stability and versatility. Also known as Vitamin C Ester, Ascorbyl Palmitate is created by bonding Vitamin C with palmitic acid, resulting in an oil-soluble and nonacidic form that is significantly more stable than the water-soluble L-Ascorbic Acid. This enhanced stability makes it ideal for formulations where oxidation, a common issue with L-Ascorbic Acid, can lead to product discoloration or degradation.

China Ascorbyl Palmitate offers numerous benefits across various industries. In the food industry, it acts as a natural preservative for oils, vitamins, and colors, keeping food, fruits, and beverages fresh while preventing the formation of unpleasant odors. It also enhances dough quality, maximizes baked food expansion, and prevents the formation of nitrous amines in processed meats. Additionally, it compensates for Vitamin C losses during food and beverage processing, ensuring nutritional value.

In the pharmaceutical sector, China L-Ascorbyl Palmitate is used to treat Vitamin C deficiencies and conditions such as scurvy, while also supporting therapies for infections, anemia, and gum diseases. Its antioxidant properties strengthen immunity and improve overall health. The personal care and cosmetics industry benefits significantly from its inclusion in products, as it promotes collagen synthesis, reduces wrinkles, and prevents pigment spots. Its antioxidant and skin-rejuvenating properties make it a key ingredient in anti-aging creams, lotions, and sun protection products.

As a highly stable and bioavailable Vitamin C derivative, China Ascorbyl Palmitate is suitable for a wide range of applications. Its oil-soluble nature allows it to penetrate deeply into tissues, delivering the multiple benefits of Vitamin C, such as improved skin elasticity, reduced blotchiness, and enhanced antioxidant activity through synergy with Vitamin E. This versatility, combined with China’s advanced manufacturing capabilities, extensive experience, and industry expertise, makes China Ascorbyl Palmitate an essential choice for businesses seeking reliable and effective solutions in food, pharmaceuticals, and cosmetics.
