1. Ethyl Ascorbic Acid Overview

Where to buy Ethyl Ascorbic Acid Powder with lowering Ethyl Ascorbic Acid price and high quality? Where to find good information of Wholesale Ethyl Ascorbic Acid and Purchase Ethyl Ascorbic Acid for sales? As the professional Ethyl Ascorbic Acid manufacturer, BFSTAR is your best choice.

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, oil, and methanol.

thyl 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.

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 ethyl ether 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

Ethyl Ascorbic Acid is a relatively acidic substance compared to other vitamin C derivatives. It is more suitable for human skin property.

7. Ethyl Ascorbic Acid Reference Formula

• Whitening cream

Preparation method：

1. Add water phase ingredients to the water phase pot; heat to 85°C; stir to dissolve, and form an aqueous phase.
2. Add oil phase ingredients to the oil phase pot, stir and heat to 85°C. After dispersing completely, then pump into the emulsification pot; then get oil phase.
3. Slowly pump ingredients in water phase pan into the emulsification pot through the filter to emulsify. After emulsifying for 25 minutes, stop homogenization; open circulating water to cool down. Keep stirring and vacuumize to defoam.
4. Cool down to 45°C; add fragrance, and stir evenly. Continue to cool down to 38°C, then discharge to obtain the cream.

• Sunscreen facial mask fluid

Preparation method：

1. Mix and dissolve ginseng extract, scutellaria baicalensis extract, and liquorice extract for 10-24 hours to obtain solution A.
2. Mix propylene glycol with 1,2-butanediol to obtain solution B.
3. Add hyaluronic acid oligomer, macromolecular hyaluronic acid, synthetic egg white powder, aloe extract, ethyl ascorbic acid to solution B. Disperse and mix by homogenizer to obtain solution C; dispersion speed of homogenizer is 10000 rpm; and for three times, each time is 5 seconds.
4. Dissolve kojic acid, nano titanium dioxide, and raspberry ketone glucoside in one-third of water solution to obtain solution D.
5. Add solution A to solution C, then add solution D, then add glycerin and the rest water to stir and dissolve. Stir in a homogenizer; disperse speed is 10,000 rpm. For three times, each time for 3 seconds. Then mask liquid is obtained.

• Anti-aging emulsion

Preparation method：

1. The oil phase ingredients are heated to 70-90°C; stir and dissolve, and pressurize 0.1-10 MPa.
2. The water phase ingredients are heated to 70-90°C; stir to dissolve, and pressurize 0.1-10Mpa.
3. Inject the water phase into the oil phase mixture; homogenize for 3-5 minutes, then stir for 15 to 45 minutes. Release the pressure, and cool down to 45°C, and then add arginine, solomonseal rhizome P.E, benincasae semen P.E., and stir evenly.

• Whitening essence

Preparation method：

The phase A is heated to 85°C. Stir until completely dissolve, and cool down to below 45°C. Then add phase B. After dissolving completely, stop stirring. And then obtain the essence.

8. Ethyl Ascorbic Acid Safety

• The CIR Expert Panel has experimentally concluded that Ethyl Ascorbic Acid is safe for use in cosmetics;
• In 2010, the Department of Health announced that ethyl ascorbic acid is a whitening ingredient that can be added to cosmetics. The dosage limit is 1-2%.

9. Packing and Storage
