Ascorbyl Palmitate/fat-soluble antioxidant, vitamin C activity, free-radical scavenger, preservative

Description

This product is L-ascorbyl palmitate (also known as vitamin C palmitate) with CAS No. 137-66-6. It is a fat-soluble vitamin C derivative prepared by the esterification reaction of vitamin C (ascorbic acid) and palmitic acid. The molecular formula of the product is C₂₂H₃₈O₇, and its molecular weight is approximately 414.53. It normally appears as a white to yellowish-white powder with a slight citrus odour, and its purity can reach over 97% (tested by HPLC). As a mature commercial bulk raw material, this product is available in various grades including food grade, cosmetic grade and pharmaceutical grade according to application purposes. It is widely used in food, cosmetics, pharmaceuticals, health food and many other fields, and is a common variety with large circulation volume in domestic and overseas markets. The product shall be stored in a sealed, light-proof, cool and dry place.

Key Effects

The most prominent feature of ascorbyl palmitate is that "it is both antioxidant and oil-soluble". Ordinary vitamin C is water-soluble and cannot function stably in oil-based products. After being combined with palmitic acid, it becomes fat-soluble vitamin C, which can be uniformly dispersed in oils and oil-containing products, effectively preventing oxidative deterioration of fats and oils and extending the shelf life of products. Meanwhile, it still exerts the effects of vitamin C in the human body and serves as a source of antioxidant nutrients. In addition, it helps preserve the natural color of food and plays an auxiliary role in antioxidation and brightening skin tone in skincare products, making it a versatile fat-soluble antioxidant ingredient.

Its specific functions can be summarized as follows:
Prevention of lipid oxidation: As a fat-soluble antioxidant, it prevents oxidative rancidity of fats, oils and oil-containing foods and extends shelf life;
Nutritional fortification: As a fat-soluble source of vitamin C, it provides nutritional fortification for foods and infant formula foods;
Color protection and freshness preservation: It helps protect natural pigments in food and prevents oxidative discoloration of products;
Protection of oxidizable components: It protects oxidizable nutrients such as vitamin A and vitamin E;
Antioxidation for skincare: Used in skincare products to help resist oxidative damage and assist in brightening skin tone;
Good formulation compatibility: It features excellent fat solubility and high stability, and can be flexibly applied in various formulations such as oil systems and emulsions.
