Ascorbyldipalmitate, with the CAS number 4218-81-9, is a fat-soluble derivative of ascorbic acid (vitamin C) formed by the esterification of ascorbic acid with palmitic acid. This compound is characterized by its antioxidant properties, which help protect against oxidative stress by neutralizing free radicals. Ascorbyldipalmitate is often used in cosmetic formulations and food products due to its ability to stabilize formulations and enhance the shelf life of products by preventing lipid oxidation. It is typically recognized for its emulsifying properties, allowing for improved texture and stability in creams and lotions. Additionally, ascorbyldipalmitate can contribute to skin health by promoting collagen synthesis and providing a source of vitamin C, albeit in a less bioavailable form compared to its free acid counterpart. Its solubility in oils rather than water makes it particularly useful in oil-based formulations. Overall, ascorbyldipalmitate serves as a multifunctional ingredient in various applications, combining the benefits of vitamin C with the stability of fatty acids.

Ascorbic acid dipalmitate is a biocompatible polymer that has been shown to be an effective agent for the treatment of staphylococcal infections. It is used in the form of crystalline cellulose and isopropyl palmitate, which are both lipophilic and thus able to cross the cell membrane. Ascorbic acid dipalmitate has been shown to inhibit bacterial growth by binding with fatty acids from exudates on the surface of bacteria, preventing them from interacting with enzymes that are required for metabolism. The molecular docking analysis of this product shows that it binds to the magnesium salt in a way that prevents its interaction with enzymes, inhibiting bacterial growth.
