All the best,

We appreciate it if you cordially arrange presentation meeting with our technical team, it should be our great pleasure to jointly work with esteemed you and your company as a global icon for technology. In addition, for your valued reference, one of the important reason to develop this product is that Shiseido Japan has formulated the same kinds ingredient - 3O-Ethyl Ascorbyl Ether in their WHITE LUCENT brand with sensational worldwide response. Thus you are kindly requested to take it into your cosideration to test either raw material itself or skin care whitening serum type CelClearC as attached photo herewith and there are two types in 10%, 30% of active ingredient - VITAMIN C derivatives.

Therefore ascorbic acid is widely used as whitening agent in many cosmetic preparation. However, ascorbic acid so chemically unstable that it is easily oxidized and becomes biologically inactive compounds under the exposure to air, light, moisture, heat, metallic ions, oxygen and bases. Therefore, in order to enhance the stability and content of ascorbic acid in the solutions, ethyl ascorbyl ether, which is the derivative of ascorbic acid with ethyl group instead of hydroxyl group, is used in many cases. The ethyl ascorbic ether is more stable and has a higher antioxidant property than the ascorbic acid. Furthermore, it can be dissolved in lipid, alcohol and various organic solvents. Therefore, as an antioxidant for cosmetic materials of water-soluble and oil-soluble compounds, it has been developed in many cosmetic formulations.

Ascorbic acid is the major water-soluble antioxidant and important in collagen formation, the skin, bone and blood vessels. As an antioxidant, ascorbic acid plays an important role for skin care and the inhibition of the melanin formation. The skin color varies with the amount of an epidermal pigment named melanin. The major function of melanin is to protect the skin against ultraviolet radiation, but excess melanin makes the skin color dim.
