Product Desciption
1.Ethyl Ascorbic Acid Overview
Ethyl Ascorbic Acid is a vitamin C derivative obtained by hydrocarbylation. It is stable to light, heat, acid, alkali; and it is not easily oxidized by air. It is a chemically stable vitamin C derivative. Also it is soluble in water,and oil.
Ethyl Ascorbic Acid can block melanin formation by inhibiting tyrosinase activity. It has effect of whitening skin. Additionally, Ethyl Ascorbic Acid has strong antibacterial and anti-inflammatory effect. It can resist inflammation caused by sunlight. Meanwhile, it can improve the dullness of skin and repair skin cells. It promotes collagen production, and has antioxidant and anti-aging effect. Ethyl Ascorbic Acid has been widely used in whitening and anti-aging cosmetics.

3.Specifications
4.Ethyl Ascorbic Acid Advantage
Vitamin C has four hydroxyl groups in its structure. It cannot be directly absorbed by skin; and it is easily oxidized to cause discoloration. As a whitening agent, it is limited in use of cosmetics. Vitamin C is prepared by 3-hydroxyl hydrocarbylation:
(1) It is a vitamin C derivative that does not change color; and it does not affect its biological activity.
(2) In addition, Ethyl Ascorbic Acid is both oil-soluble and water-soluble. It allows it to be arbitrarily added to oil phase or aqueous phase of cosmetic formulation,. Also it can be added at high temperature or low temperature. So it is convenient to be applied in cosmetics.
(3) More importantly, its solubility makes it easier to penetrate stratum corneum into dermis to exert its biological effects.
Compared with other vitamin C derivatives, Ethyl Ascorbic Acid has advantages in solubility and pH stability, as shown in the following tables:
Comparison of vitamin C content and solubility
As can be seen from the above table, Ethyl Ascorbic Acid has the highest vitamin C content, and has the smallest molecular weight; it is both water-soluble and oil-soluble. It is more favorable to be absorbed by skin.
Comparison of pH stability
5. Ethyl Ascorbic Acid Benefits
Ethyl Ascorbic Acid is easily decomposed by enzymes after being absorbed by skin. Thereby it plays the role of vitamin C in skin care:
1.Anti-aging
Ethyl Ascorbic Acid is effective against free radicals. It can resist damage caused by UVA and UVB. Ethyl Ascorbic Acid prevents skin cells from aging and damage. It can help body to reduce the harmful free radicals produced by metabolism, and effectively fight free radicals.
2.Skin-whitening
Ethyl Ascorbic Acid directly can reduce melanin to colorless reduced melanin. Then it exerts effect of whitening skin and lightening spots. It is also capable of reducing o-quinone by its own antioxidant activity; and it inhibits catalase activity to achieve the effect of inhibiting melanin formation.
3.Anti-inflammatory
Ethyl Ascorbic Acid promotes the synthesis and repair of collagen. It is effective against carbonation and saccharification. Thus it significantly resists inflammation on skin surface.
4.Promote collagen synthesis
Ethyl Ascorbic Acid has the activity of repairing collagen (including repairing the composition and synthesis of collagen). It can promote formation of skin cells and synthesis of collagen according to the ratio of skin cells and collagen consumption. Therefore, it makes skin shiny and elastic.

2. Ethyl Ascorbic Acid SourceEthyl Ascorbic Acid is synthesized from vitamin C. The following are two common synthetic methods:
| One-step synthesis | Three-steps synthesis | |
| Procedure | Ethyl Ascorbic Acid is obtained by directly hydrolyzing 3-hydroxyl group using vitamin C and ethyl methanesulfonate or diethyl sulfate as raw materials. | A series of reactions are carried out using vitamin C as raw materials and anhydrous copper sulfate as a catalyst to obtain Ethyl Ascorbic Acid. |
| Advantage | Less steps, simple operation. | Raw material is easy to get. Low cost, stable yield, high purity and easy to be industrialized. |
| Disadvantage | Hydroxyl group is replaced by many positions; and the product is difficult to be separated. It needs to be purified by column chromatography and is not suitable for industrial production. | / |
