Ascorbyl palmitate (L-Ascorbic acid 6-hexadecanoate), an ester formed from ascorbic acid and palmitic acid, produces a fat-soluble form of vitamin C.

Applications Ascorbyl Palmitate is an ester formed from ascorbic acid (A786990) and palmitic acid (P144500) creating a fat soluble form of vitamin C. Ascorbyl Palmitate is also used as an antioxidant food additive.

Ascorbyl palmitate is an ester of ascorbic acid and palmitic acid. It is a water-soluble antioxidant that has been shown to be safe for oral ingestion at doses of up to 3 grams per day. Ascorbyl palmitate is used in topical formulations to provide protection against sun damage, and also has been shown to have anti-inflammatory properties, which may be due to its inhibitory effect on the mcl-1 protein. Ascorbyl palmitate has a phase transition temperature at about 41°C. This compound can be used in pharmaceuticals for the treatment of infectious diseases caused by bacteria such as tuberculosis or herpes simplex virus type 1 (HSV-1). This chemical also has been shown to have physiological effects on bowel disease and toxicity studies show that it does not cause any adverse reactions in rats or rabbits when given orally.

L-Ascorbyl palmitate (Asc-6P) is used along with other fatty acid ascorbates such as L-ascorbyl oleate and L-ascorbyl linoleate to protect cells and membranes from oxidative damage. Fatty acid ascorbate molecules have increased solubility in non-polar (lipophilic) environments. It is applied as hume
