3-O-Ethyl-L-ascorbic acidmuaj ob yam khoom ntawm cov roj hydrophilic thiab ruaj khov heev hauv tshuaj. 3-O-Ethyl-L-ascorbic acid, tus lej cas 86404-04-8, muaj cov khoom oleophilic thiab hydrophilic ua cov vitamin C derivative, uas nthuav dav nws cov ntawv thov, tshwj xeeb tshaj yog hauv kev siv tshuaj txhua hnub.

Cov vitamin C ib txwm nyuaj rau nqus los ntawm daim tawv nqaij thiab muaj bioavailability qis. Cov khoom hydrophilic thiab lipophilic ntawm 3-O-Ethyl L-ascorbic acid ua rau nws yooj yim dua rau nkag mus rau hauv stratum corneum thiab nkag mus rau hauv dermis. Tom qab nkag mus rau hauv daim tawv nqaij, 3-O-Ethyl L-Ascorbic acid yooj yim decomposed los ntawm cov enzymes biological los ua lub luag haujlwm ntawm vitamin C, yog li txhim kho nws cov bioavailability.

Ntxiv rau, 3-O-Ethyl-L-ascorbic acid yog cov vitamin C uas pom ntau, uas kuj qhia tau tias muaj kev ruaj khov siab kom ntseeg tau tias muaj VC, thiab ua tiav qhov cuam tshuam ntawm kev ua kom dawb thiab ua rau tawv nqaij qhuav.

Cov Khoom: 3-O-Ethyl-L-ascorbic acid yog dawb los yog dawb crystalline hmoov zoo li. Nws yog ib qho ntawm cov derivatives zoo tshaj plaws ntawm vitamin C txog niaj hnub no. Nws tsis yog tsuas yog ruaj khov hauv tshuaj lom neeg xwb, tab sis kuj yog ascorbic acid derivative uas tsis yooj yim hloov xim tom qab nkag mus rau hauv daim tawv nqaij. Nws yog metabolized tib yam li vitamin C hauv lub cev, yog li ua rau muaj txiaj ntsig zoo dua ntawm ascorbic acid.

Txoj kev ua haujlwm: 3-O-Ethyl-L-ascorbic acid tiv thaiv tyrosinase kev ua haujlwm thiab kev tsim cov melanin los ntawm kev ncav cuag txheej basal los ntawm stratum corneum ntawm daim tawv nqaij, txo cov melanin kom tsis muaj xim, ua haujlwm zoo hauv kev ua kom dawb thiab tshem tawm cov quav hnav. 3-O-Ethyl-L-ascorbic acid kuj tseem tuaj yeem koom nrog ncaj qha rau hauv kev tsim cov collagen tom qab nkag mus rau hauv dermis, uas ua rau collagen ntau ntxiv, yog li ua rau daim tawv nqaij puv thiab ywj.

Cov Haujlwm Tseem Ceeb:

(1) Kev txwv tsis pub ua tyrosinase thiab tiv thaiv kev tsim melanin; Txo melanin, ua kom cov pob me me thiab dawb.

(2) Muaj zog antioxidant nyhuv, zoo tshem tawm cov dawb radicals.

(3) Kev ruaj khov zoo, tiv taus lub teeb, tiv taus kub, tiv taus kua qaub thiab alkali, tiv taus huab cua oxidation. Muaj bioavailability siab, roj hydrophilic, yooj yim nqus tau ntawm daim tawv nqaij.

(4) Tiv thaiv kom daim tawv nqaij o los ntawm tshav ntuj.

(5) Txhawb kev tsim cov collagen thiab ua rau daim tawv nqaij elasticity.

3-O-Ethyl-L-ascorbic acidmuaj cov haujlwm ntawm kev kho collagen (suav nrog kev kho collagen muaj pes tsawg leeg thiab kev tsim ua ke), uas tuaj yeem txhawb kev tsim cov hlwb tawv nqaij thiab kev tsim collagen raws li qhov sib piv ntawm cov hlwb tawv nqaij thiab kev noj collagen, yog li ua rau daim tawv nqaij ci ntsa iab thiab ywj. Vitamin C ethyl ether yog siv dav hauv kev ua kom dawb freckle thiab tiv thaiv kev laus ntawm cov khoom siv tawv nqaij, xws li tshuaj pleev, tshuaj pleev, toner, daim npog ntsej muag, essence thiab lwm yam.

Kev siv khoom:

Cov khoom no yog siv rau hauv cov khoom ua kom dawb, cov khoom tiv thaiv kev laus, dej, gel, essence, tshuaj pleev, tshuaj pleev tawv nqaij thiab lwm yam.

[Cov tshuaj pom zoo] 0.1-2.0%, tsim nyog rau kev ua kom dawb thiab tshem tawm cov quav hnav, tshem tawm cov tawv nqaij ntsws thiab cov khoom tiv thaiv kev laus.

[Kev ua haujlwm pom zoo] Nws yog qhov zoo tshaj plaws los siv rau hauv qab PH3.0-6.0 cov xwm txheej, thiab qhov ua kom dawb thiab freckle nyhuv yog qhov zoo tshaj plaws.

3-O-ethyl-L-ascorbiccov kua qaub yuav yog ib qho stabilizer pab tau rau cov kua p-hydroxyacetophenone.

Cov teebmeem ntawm vitamin C ethyl ether rau ntawm daim tawv nqaij:

Kev txwv tsis pub ua tyrosinase los ntawm kev ua haujlwm ntawm Cu2 + thiab thaiv cov melanin tsim;

Ua kom dawb thiab tshem tawm cov quav hnav zoo heev (2% thaum ntxiv);

Tiv thaiv kev o los ntawm lub teeb, muaj cov tshuaj tua kab mob thiab tiv thaiv kev o;

Txhim kho daim tawv nqaij ci ntsa iab, muab daim tawv nqaij elasticity;

Kho cov haujlwm ntawm daim tawv nqaij thiab txhawb kev tsim cov collagen.
