ASCORBYL GLUCOSIDE(Cas 129499-78-1) Usage
|
Biochem/physiol Actions |
2-O-a-D-glucopyranosyl-L-ascorbic acid or ascorbyl glucoside functions as a skin whitener and radical scavenger in cosmetics. It is responsible for the bleaching action of bleaching cosmetics. This compound is activated in a manner identical to that of vitamin C. The enzyme present in the epidermal basal membrane, ascorbyl phosphatase, slowly converts 2-O-a-D-glucopyranosyl-L-ascorbic acid into vitamin C, thereby maintaining a high vitamin C level in skin throughout the day. |
|
General Description |
Ascorbyl glucoside is a stable form of vitamin C combined with glucose. When properly formulated and absorbed into skin, it breaks down to ascorbic acid (pure vitamin C).2-O-a-D-Glucopyranosyl-L-ascorbic Acid is a useful cosmetic gel and skin cleanser. Once absorbed, its breakdown to vitamin C is gradual, creating what’s known as a reservoir effect within skin. This leads to longer-lasting benefits. |
