Is Ester C as good as vitamin C?
What Is Vitamin CEthyl Ether?
Vitamin C is a well-known whitening ingredient and also has the function of promoting collagen synthesis. Vitamin C is often used as an antioxidant and has reducing properties. It can inhibit the oxidation of melanin intermediate dopaquinone into melanin, and at the same time convert dark oxidized melanin into light-colored reduced melanin, thereby playing a role in whitening the skin. However, vitamin C is water-soluble and not easy to penetrate into the stratum corneum of the skin. It is also easy to oxidize and difficult to preserve. Vitamin C itself has poor stability and is not easily absorbed by the skin, so people have been striving to find a way to convert vitamin C into a substance that is stable and easily absorbed by the skin. Preparing it into a derivative is one of the main ways at present.
Vitamin C ethyl ether, also known as 3-O-ethyl ascorbic acid, is a very useful vitamin C derivative. It is not only very stable in terms of chemical substances and is a non-discoloring vitamin C derivative, but also a hydrophilic and lipophilic substance. This not only makes it extremely convenient to use in formulas, but also makes it easy to penetrate the stratum corneum and enter the dermis. After entering the skin, it is easily decomposed by biological enzymes to play the role of vitamin C, thereby improving its bioavailability.
What Are The Advantages Of Vitamin C Ethyl Ether?
1.High stability
VC ethyl ether is obtained by etherifying the C3 hydroxyl group of VC, making VC inert, thus avoiding VC from being oxidized and destroyed and having good stability. It is a non-discoloring vitamin C derivative.
Under the conditions of room temperature 25℃ and high temperature 45℃, the retention rate of VC ethyl ether remains above 90% for 15 days, which is much better than the prototype VC and other VC derivatives (the ten-day preservation rate is 14.25-18.3%).
2.Mild and low irritation
The pH value (acidity and alkalinity) of the human skin surface is weakly acidic, approximately between 4.5 and 6.5. The pH value of 3-O-ethyl ascorbic acid is closest to human skin and is safer.
3.High conversion rate and easy absorption
VC ethyl ether is very easy to be decomposed by biological enzymes in the body after entering the body, and the VC content can reach 86.3%, which is high in VC content.
It has an amphiphilic structure of lipophilic and hydrophilic. Compared with the hydrophilic prototype VC, it is easier to penetrate the stratum corneum and enter the dermis, thereby exerting its biological efficacy and can play a role for a long time.
What Are The Functions Of Vitamin C Ethyl Ether?
1.Whitening and freckle removal
VC ethyl ether can inhibit the activity of tyrosinase in the skin, thereby preventing the formation of melanin and achieving a whitening effect. At the same time, it can also promote skin metabolism and help remove pigment spots that have already formed. Compared with VC, VC ethyl ether is very stable and does not change color. It truly achieves the effect of whitening and freckle removal.
2.Antioxidant
VC ethyl ether is a powerful antioxidant that can quickly capture and remove free radicals in the body, prevent oxidative damage to skin cells caused by free radicals, and thus protect the skin from pigmentation problems caused by external factors such as ultraviolet rays.
3.Anti-aging
The hydroxylation of proline in the synthesis of collagen requires the participation of VC and VC derivatives. VC deficiency will lead to abnormal synthesis of collagen. After entering the dermis, VC ethyl ether directly participates in the synthesis of collagen to repair the activity of skin cells, increase collagen, and make the skin full and elastic, making the skin delicate and smooth.
4.Antibacterial and anti-inflammatory
VC ethyl ether can inhibit the activity of 5-hydroxylamine in the skin, reduce skin inflammatory reactions, inhibit skin redness caused by inflammation, and significantly remove yellowness and even skin color.
What Is The Application Of Vitamin C Ethyl Ether?
In daily chemical products, vitamin C ethyl ether is widely used, and its lipophilic and hydrophilic properties enable it to adapt to a variety of environments and application scenarios.
In the cosmetics industry, the application of vitamin C ethyl ether is mainly reflected in its antioxidant and whitening effects. It can inhibit the oxidation of melanocytes, prevent the formation of spots, lighten spots, brighten skin tone, promote collagen regeneration, help the skin resist external invasion, and improve skin fatigue, sallowness and other problems.
In the food industry, vitamin C ethyl ether is mainly used as an antioxidant for oils, beverages, cold drinks, meat processing products, etc. In addition, it is also used as a natural dye for dyeing natural fibers such as wool and cotton, providing a variety of color options, and good soap resistance and sun resistance.
Vitamin C ethyl ether is also widely used in various foods, beverages, health products, feed, agriculture, industry, biochemical research and other fields as food additives, feed additives, fertilizer additives, raw materials, etc. Its stability and effectiveness make it an indispensable ingredient in these industries.
