1. Food Processing and Preservation

Food-grade ascorbyl palmitate is a commonly used natural fat-soluble antioxidant in the food industry, suitable for various applications including oils, baked goods, meat products, dairy products, and infant formula. In oils and fried foods, it can be added to vegetable oils, animal fats, potato chips, instant noodles, and other products. It can scavenge free radicals produced during oil oxidation, inhibit lipid peroxidation, delay rancidity, and extend product shelf life without affecting the original flavor of the oil. In baked goods, it is used in bread, cakes, and biscuits to inhibit the oxidation of fats in the dough, preventing rancidity in the finished product, while also improving dough gas retention and the softness of the finished product, extending its shelf life. In meat products, it is added to sausages, ham, and cured meats to inhibit the oxidative discoloration of myoglobin, maintaining the bright color of the meat, while also delaying fat oxidation and improving product quality stability. In infant formula, it serves as a nutritional fortifier to supplement vitamin C, and its fat-soluble properties make it more easily absorbed by infants, meeting the stringent safety standards for infant food. It is highly safe and is an antioxidant permitted for use under the Chinese national standard GB 2760. We can provide food-grade raw materials of different purity specifications to food companies, along with comprehensive food-grade testing reports and application ratio recommendations.

2. Health Supplements and Nutritional Fortification

Ascorbyl palmitate is a core raw material for fat-soluble vitamin C supplements, addressing the problem of ordinary vitamin C's high water solubility and difficulty in remaining in fatty tissues. It can be more efficiently absorbed by the human body and acts at the cellular membrane level. It can be developed into single-ingredient preparations such as capsules, softgels, and tablets, or combined with vitamin E, coenzyme Q10, and unsaturated fatty acids, focusing on "fat-soluble antioxidant," "cellular anti-aging," and "synergistic immune enhancement" selling points, precisely targeting people who focus on cellular antioxidant protection, middle-aged and elderly people seeking physical conditioning, and sports and fitness enthusiasts. Its strong stability prevents decomposition and inactivation during production and storage. We can provide food-grade raw materials to health supplement companies, along with antioxidant activity test reports and support for cross-border e-commerce compliance claims.

3. Cosmetics and Personal Care Products

Cosmetic-grade ascorbyl palmitate is an antioxidant and repair ingredient in high-end skincare products. Its lipid-soluble properties allow it to penetrate the stratum corneum of the skin, reaching deep into the skin to exert its effects. In skincare products, it is used in anti-aging creams, serums, lotions, and sunscreens. It can scavenge free radicals in skin cells, inhibit photoaging caused by ultraviolet radiation, reduce the formation of fine lines and wrinkles, and improve dull and rough skin. It also promotes collagen synthesis, improves skin elasticity and firmness, and enhances the skin barrier function, relieving redness, dryness, and discomfort in sensitive skin. Compared to water-soluble vitamin C, it is less irritating, more stable, and less likely to decompose due to light and high temperatures, making it suitable for all skin types. It can be combined with ceramides, hyaluronic acid, and vitamin E, focusing on "gentle antioxidant" and "anti-aging repair" benefits.
