What is 3-O-Ethyl-L-Ascorbic Acid?

3-O-Ethyl-L-Ascorbic Acid is a very beneficial vitamin C derivative. It is not simply exceptionally secure in chemical materials, it is a non-discoloring vitamin C derivative, as well as also it is lipophilic as well as hydrophilic. It has significantly expanded its series of application, especially in day-to-day chemistry. 3-O-Ethyl-L-Ascorbic Acid can swiftly get in the dermis with the stratum corneum. After going into the body, it is extremely straightforward to be decayed by the organic enzymes in the body to put in the organic results of vitamin C.

Because vitamin C has 4 hydroxyl groups in its framework, it can not be straight absorbed by the skin, in addition to it is conveniently oxidized to create staining. As a bleaching agent, its use in cosmetics is limited. The vitamin C ethyl ether gotten after the 3-hydroxyl is alkylated is a vitamin C by-product that does not change color and additionally does not impact its organic activity, hence filling out the gap on the market for similar products. Studies have actually disclosed that 3-O-Ethyl-L-Ascorbic Acid gets in the skin as well as is conveniently broken down by enzymes to play the function of vitamin C.

Application of 3-O-Ethyl-L-Ascorbic Acid

3-O-Ethyl-L-Ascorbic Acid (vitamin C ethyl ether) is an oil-water soluble material, which permits the formulator to include it to the oil stage or water phase, and also can also be included at high or low temperature level, so that it is convenient Much more significantly, this twin solubility makes it easier to penetrate the stratum corneum as well as get in the dermis to exert its organic results, which is not readily available in various other vitamin C by-products. It can block the development of melanin by inhibiting the activity of tyrosinase; it has bleaching and freckle elimination impacts (when 2% is included); it can resist swelling triggered by sunshine and has solid antibacterial as well as anti-inflammatory effects; The skin is glossy as well as elastic, the activity of skin cells is fixed, and also the production of collagen is promoted.

CN201610866558.7 provides a whitening composition, which includes the extract of euphorbic acid, 3-O-Ethyl-L-Ascorbic Acid and auxiliary agents, further, the whitening composition includes 0.5~5.0wt% of euphorbic acid Huoxuedan extract, 0.2-3.0wt% 3-O-ethyl ascorbic acid and the balance of additives. In the present application, by adding the extract of euproxetan and 3-O-Ethyl-L-Ascorbic Acid to the whitening composition, the resulting composition has a better whitening effect; further, the above two components are compounded , so that the whitening composition achieves the best whitening effect, and the mildness is better. The present application also provides a skin care product.

CN201510804504.3 discloses a manufacturing method of peony whitening facial cleanser, comprising the following steps: adding glycerin, glyceryl glucoside, myristic acid, ascorbyl phosphatidic acid, palmitic acid, potassium hydroxide, 3-O-Ethyl-L-Ascorbic Acid, Macrogol-8, Hydroxyethyl Cellulose, Butylated Hydroxytoluene, Methylparaben, Sodium Methyl Lauroyl Taurate, Polyquaternium-39, Disodium EDTA, Glyceryl Oleate, Benzene Put oxyethanol, methylisothiazolinone, butanediol and deionized water in a container, heat to 90°C and stir to dissolve; keep warm for 10 minutes and cool to 30°C; add peony root extract, oat amino acids, bamboo leaf extract Stir for 3-10 minutes; add 1.8-2.2 parts of citric acid to adjust the pH value; let it stand for defoaming, cool to room temperature, and fill it into a finished product.
