A. Chemical Structure and Composition
Ascorbyl Palmitate, also known as vitamin C ester or ascorbyl-6-palmitate, has a chemical structure that combines the antioxidant properties of ascorbic acid (vitamin C) with the lipid-solubility of palmitic acid. The chemical formula for ascorbyl palmitate is C22H38O7. Let's break down its chemical structure:
Ascorbic Acid Component:
The ascorbic acid portion of ascorbyl palmitate is derived from vitamin C. It contains a six-membered lactone ring with a ketone functional group (C=O) and two hydroxyl groups (-OH). This part is responsible for the antioxidant properties of ascorbyl palmitate.
Palmitic Acid Component:
The palmitic acid portion is a 16-carbon fatty acid, typically saturated. It is attached to the ascorbic acid through an ester bond, which is formed by the reaction between the hydroxyl group of ascorbic acid and the carboxyl group of palmitic acid.
The ester bond between ascorbic acid and palmitic acid is represented as -C(O)-O-. This esterification results in the formation of a compound that is both water-insoluble (lipid-soluble) and more stable in certain formulations compared to the water-soluble ascorbic acid.
The combination of these components makes ascorbyl palmitate suitable for use in oil-based products such as creams, lotions, and other cosmetic formulations. Its chemical structure allows it to penetrate lipid-rich cell membranes more effectively, enhancing its bioavailability and antioxidant action in skincare applications.
