Applications

Ascorbyl palmitate is used as an antioxidant in food and cosmetic industry; or a nutrition strength modifier; and it also can be used as an active pharmaceutical ingredient.
Antioxidant: Colour retention agent to protect oxidizable natural pigment(such as Capsorubin, Lycopene, Carotene, lutein, etc). Liposoluble antioxidant in animal and vegetable fat and foods to stabilize soybean oil, cottonseed oil, palm oil, unsaturated fat; Antioxidant in baby milk products to prevent baby  milk product oxidation. Infired products(such as instant noodle, potato chip, fried meat products,etc.) to prevent lipid oxidation and prolong its shelf life.
Chemical daily product: lipsoluble whitening and freckle removing product.
Medicine and health care:Protects the active ingredients and oxidation of the drug. As a VC nutritional fortifier, this product is less irritating to the stomach than VC.
