L-Ascorbyl Palmitate
Synonyms:vitamin C palmitate, L-ascorbyl-6-palmitate, 3-oxo-L-gulofuranolactone 6-palmitate.
Chemical formular: C22H38O7
Molecular weight: 414.54
CAS No.137-66-6
Description:
Ascorbyl palmitate is a white or yellowish powder having a slight odor. It is very slightly soluble in water and in vegetable oils. Ascorbic acid comprises 42.5% of the weight of ascorbyl palmitate.
Ascorbyl palmitate is a synthetic ester comprised of the 16-carbon chain saturated fatty acid palmitic acid and L-ascorbic acid.It is used as an antioxidant in foods, pharmaceuticals and cosmetics, and is also used as a preservative for the natural oils, oleates, fragrances, colors, vitamins and other edible oils and waxes which are used in pharmaceuticals, cosmetics and foods.
Ascorbyl palmitate is marketed as a nutritional supplement and claimed to be a superior delivery form of vitamin C. Since ascorbyl palmitate is a fat-soluble derivative of ascorbic acid, theoretically it can concentrate into the lipid domains of biological systems and protect cell membranes and low density lipoproteins (LDL) against oxidation.
