Applications of Ascorbyl Palmitate
- Food-grade Ascorbyl Palmitate can be used as a food additive in oil-containing foods, instant rice and noodle products, and infant formula.It can not only effectively supplement the vitamins the human body needs, but also prevent food oxidation and delay spoilage.
- Food-grade Ascorbyl Palmitate can be used to produce various nutritional supplements, primarily in soft capsule form, with tablets, powders, or other forms as secondary options.It has high compatibility with other ingredients and is suitable for supplementation by various groups of people.This includes people with sensitive digestive systems, those with weakened immune systems, those needing mineral supplements, and those seeking general health maintenance.
- Feed-grade Ascorbyl Palmitate is used as an additive in pet food, aquatic feed, and livestock and poultry feed.It can serve as a source of vitamins and also prevent the oxidation and deterioration of nutrients in feed, as well as prevent a decline in palatability.
- Cosmetic-grade Ascorbyl Palmitate is one of the widely used vitamin C derivatives in cosmetic applications.It is a key ingredient in whitening, anti-aging, and antioxidant products,and it boasts the advantages of being stable, gentle, having multiple functions, and being highly compatible.
- Cosmetic-grade Ascorbyl Palmitate is suitable for all skin types and skin care.It can also be used for hair care, preventing dryness and yellowing of the hair.
- Pharmaceutical-grade Ascorbyl Palmitate can be used as a high-quality antioxidant and pharmaceutical/nutritional excipient, for example, as a stabilizer in pharmaceutical ointments and capsule formulations.
- Industrial-grade Ascorbyl Palmitate can be used for the large-scale processing and continuous production of other high-value vitamin C derivatives and lipid-soluble fine chemicals.
- Industrial-grade Ascorbyl Palmitate is added in small quantities during the production and processing of plastics, coatings, and other materials. This helps prevent yellowing and aging caused by oxidation, improving the appearance and stability of the products.
