Kev siv
Ethyl Ascorbic Acidyog ib qho txiaj ntsig zoo vitamin C derivative. Nws tsis yog tsuas yog siv cov siv tawv heev, ua cov tshuaj pleev ib ce uas tsis yog qhov, 3-O-ER-ER-ERHYR ASCORBIC ACCID ETHET YUAV TAU TXAIS LUB CEV CORUMBE thiab mus txog rau Dermis. Thaum nws nkag rau lub cev, nws yog qhov tseeb decomposed los ntawm cov roj ntsha enzymes hauv lub cev, yog li exerting txoj kev siv roj ntsha ntawm vitamin C.
Ethyl ascorbic acid (vc ethyl ether ether)yog amphiphilic vitamin C derivative uas yog ob qho lipophilic thiab hydrophilic. Nws tsis tsuas yog khaws cov redox ua haujlwm ntawm vitamin C tab sis kuj tseem ruaj khov. Nws yog qhov tsis-plhaw vitamin C deramin C deramin C deramin C deramin C derivative. Ntxiv mus, ua cov tshuaj amphipilic, nws yooj yim heev rau kev siv hauv cov qauv. Dab tsi ntxiv, nws tuaj yeem nkag mus rau hauv stratum Corneum thiab nkag rau hauv dermis. Thaum nws nkag los ntawm daim tawv nqaij, nws yog qhov tseeb decomposed los ntawm cov roj ntsha enzymes kom tau siv zog ua haujlwm ntawm vitamin C, yog li txhim kho nws cov bioavailability.
3-O-ER-ERHYL ASCORBIC acid ether (Asthyl ascorbic acid)yog ib yam khoom uas yog soluble hauv ob qho roj thiab dej. This allows formulators to add it to either the oil phase or the water phase, and it can also be added at high or low temperatures, making it very convenient to use. Qhov tseem ceeb tshaj, qhov chaw amphipilic no tuaj yeem nkag rau hauv stratum Corneum tau yooj yim dua rau lwm cov vitamin C derivatives. Nws tuaj yeem cuam tshuam qhov kev ua si ntawm Tyrosinase los thaiv kev tsim ntawm Melanin; Nws muaj whitening thiab fryckle-tshem cov teebmeem (thaum ntxiv ntawm 2%); Nws tuaj yeem tiv thaiv mob tshwm sim los ntawm lub hnub ci thiab muaj cov tshuaj tua kabmob muaj zog thiab tiv thaiv kev cuam tshuam; Nyob rau tib lub sijhawm, nws tuaj yeem txhim kho cov tawv nqaij thiab cov tawv nqaij uas muaj cov tawv nqaij, kho cov kev ua si ntawm cov tawv nqaij, thiab txhawb nqa cov tawv nqaij collagen.
