O-ethyl ascorbic acid is the most stable derivative of Ascorbic Acid (AA) known so far.
As an ethyl ether derivative, Ethyl Ascorbic Acid (EAA) presents higher lipophilicity, increasing bioavailability and improving efficacy compared to free ascorbic acid. |
In contrast to free AA, Ethyl Ascorbic Acid freely penetrates into skin, where it is further metabolized to Ascorbic Acid, ensuring a remarkable higher bioavailability and a consequent higher concentration in deeper skin target sites. 3-O-ethyl ascorbic acid presents an outstanding stability in all kind of cosmetic formulations, without any color change at pH 3.0-6.0. |
| • Inhibits Tyrosinase activity, preventing melanin synthesis. • Improves skin complexion and enhances its elasticity. • Outstanding antioxidant performance. • Accelerates and improves collagen production. |
• Free radical scavenger. Protects skin from environmental and intrinsic stress factors. • Reduces inflammation and inhibits the formation of edema. • Excellent stability to light, heat, acid, alkali, salt and oxygen. |
