Ascorbyl palmitate
A fat-soluble form of vitamin C
Ascorbyl palmitate is a fat-soluble form of vitamin C, also known as ascorbic acid. It is an ester formed from ascorbic acid and palmitic acid, a common fatty acid found in both animals and plants. Ascorbyl palmitate is used in the food industry as an antioxidant and is also found in various cosmetic and pharmaceutical products.
Chemical properties[edit | edit source]
Ascorbyl palmitate is a white to yellowish powder with a slight citrus odor. It is soluble in fats and oils, which allows it to be used in lipid-based formulations. The chemical structure of ascorbyl palmitate consists of the ascorbic acid moiety esterified with palmitic acid, making it more stable than ascorbic acid alone.
Uses[edit | edit source]
Food industry[edit | edit source]
In the food industry, ascorbyl palmitate is used as an antioxidant to prevent the oxidation of fats and oils, thereby extending the shelf life of food products. It is often added to margarine, vegetable oils, and snack foods.
Cosmetics[edit | edit source]
Ascorbyl palmitate is used in cosmetic formulations for its antioxidant properties. It helps to protect the skin from oxidative damage caused by free radicals and ultraviolet radiation. It is commonly found in skin creams, lotions, and sunscreens.
Pharmaceuticals[edit | edit source]
In the pharmaceutical industry, ascorbyl palmitate is used as an antioxidant in drug formulations to enhance the stability of active ingredients. It is also used in vitamin C supplements as a source of vitamin C that is more stable and less acidic than ascorbic acid.
Health effects[edit | edit source]
Ascorbyl palmitate is considered safe for use in food and cosmetics. It is metabolized in the body to release ascorbic acid and palmitic acid, both of which are naturally occurring substances. As a form of vitamin C, it contributes to the maintenance of normal immune function, collagen synthesis, and antioxidant protection.
