Ascorbic Acid (Vitamin C Powder)

Vitamin C, 100% L-Ascorbic Acid, FCC, Ultrafine powder is a water soluble antioxidant. Vitamin C, a potent, naturally occurring antioxidant which plays a pivotal role in the prevention of dry skin and wrinkles, collagen synthesis and skin regeneration. Ascorbate is found in all layers of the skin, but is more concentrated in the epidermis than the dermis. However, it is readily depleted by about two thirds in cutaneous tissue stores with exposure to UV light. Biochemically, the body relies on ascorbate in the collagen biosynthetic pathway. It functions as a cofactor for two enzymes, lysyl and prolyl hydroxylases. These are dependent on iron and Vitamin C prevents iron oxidation and thus inactivation of these hydroxylases, thereby maintaining their activity.

Topical application of Vitamin C has been shown to reduce the appearance of fine lines and wrinkles. Caused by mechanisms supporting collagen production, this leads to improving the appearance of the skin. It has further been proven to reduce the severity of sunburns and age spots.

This is a cosmetic raw material and is meant for external use only in cosmetic formulations. As with all of our materials, it should not be taken internally.

The difficulty for the cosmetic formulator is that L-Ascorbic Acid is very unstable in aqueous solutions, as it starts to oxidize immediately, gradually producing color changes (orange/brown shift) and a reduction in activity as it converts to dehydroascorbic acid. For cosmetic use, it is best stabilized in an anhydrous lipid or silicone base, although some have reported increased stability with the use of Ferulic Acid as part of aqueous formulations. This product is an ultrafine powder, ready to use in anhydrous formulations without further grinding.
