3-O-Ethyl-L-ascorbic asidiali ndi katundu wapawiri wa mafuta a hydrophilic ndipo ndi okhazikika pamankhwala. 3-O-Ethyl-L-ascorbic acid, cas number 86404-04-8, ili ndi oleophilic ndi hydrophilic katundu monga vitamini C yochokera, yomwe imawonjezera kuchuluka kwake kwa ntchito, makamaka mu chemistry ya tsiku ndi tsiku.

Vitamini C wamba ndizovuta kutengeka ndi khungu ndipo amakhala ndi bioavailability yochepa. Mphamvu ya hydrophilic ndi lipophilic ya 3-O-Ethyl L-ascorbic acid imapangitsa kuti zikhale zosavuta kulowa mu stratum corneum ndikulowa mu dermis. Pambuyo polowa pakhungu, 3-O-Ethyl L-Ascorbic acid imawonongeka mosavuta ndi michere yachilengedwe kuti igwire ntchito ya vitamini C, potero kuwongolera kupezeka kwake.

Komanso, 3-O-Ethyl-L-ascorbic asidi ndi wamba vitamini C, amene amasonyezanso kukhazikika mkulu kuonetsetsa kupezeka kwa VC, ndi kukwaniritsa kwenikweni zotsatira za whitening ndi freckling.

Katundu: 3-O-Ethyl-L-ascorbic asidi ndi woyera kapena woyera crystalline ufa mu maonekedwe. Ichi ndi chimodzi mwazinthu zabwino kwambiri zochokera ku vitamini C mpaka pano. Sizingokhala zokhazikika pamankhwala, komanso zotumphukira za ascorbic acid zomwe sizimasungunuka mosavuta mukalowa pakhungu. Imapangidwanso mofanana ndi vitamini C m'thupi, motero imakhala ndi zotsatira zabwino za ascorbic acid.

Njira yochitira: 3-O-Ethyl-L-ascorbic acid imalepheretsa ntchito ya tyrosinase ndi mapangidwe a melanin pofika pamtunda woyambira pakhungu, kuchepetsa melanin kuti ikhale yopanda mtundu, yothandiza poyera komanso kuchotsa mabala. 3-O-Ethyl-L-ascorbic asidi angathenso mwachindunji nawo kaphatikizidwe kolajeni pambuyo kulowa dermis, amene kumawonjezera kolajeni, potero kupanga khungu kudzaza ndi zotanuka.

Ntchito zazikulu:

(1) Kuletsa ntchito ya tyrosinase ndikuletsa kupanga melanin; Chepetsani melanin, pezani mawanga ndikuyera.

(2) Mphamvu ya antioxidant, kuchotsa bwino ma radicals aulere.

(3) Kukhazikika kwabwino, kukana kuwala, kukana kutentha, kukana kwa asidi ndi alkali, kukana kwa okosijeni. High bioavailability, hydrophilic mafuta, mayamwidwe mosavuta khungu.

(4) Pewani kutupa khungu chifukwa cha kuwala kwa dzuwa.

(5) Limbikitsani kupanga kolajeni ndikuwonjezera kutha kwa khungu.

3-O-Ethyl-L-ascorbic asidiali ndi ntchito yokonza kolajeni (kuphatikizapo kukonza kolajeni ndi kaphatikizidwe), zomwe zingalimbikitse mapangidwe a khungu ndi kaphatikizidwe ka collagen malinga ndi chiŵerengero cha maselo a khungu ndi kumwa kolajeni, kuti khungu likhale lonyezimira komanso zotanuka. Vitamini C ethyl ether amagwiritsidwa ntchito kwambiri poyeretsa ma freckle ndi anti-kukalamba kusamalira khungu, monga mafuta odzola, zonona, toner, mask, essence ndi zina zotero.

Kugwiritsa ntchito mankhwala:

Izi zimagwiritsidwa ntchito popanga zoyera, zotsutsana ndi ukalamba, madzi, gel osakaniza, essence, mafuta odzola, zonona zosamalira khungu ndi zina zotero.

[Mlingo wovomerezeka] 0.1-2.0%, woyenera kuyeretsa ndi kuchotsa madontho, kuchotsa makwinya ndi mankhwala oletsa kukalamba.

[Opaleshoni yolangizidwa] Ndibwino kugwiritsa ntchito pansi pa PH3.0-6.0 mikhalidwe, ndipo kuyera ndi madontho ndikobwino kwambiri.

3-O-ethyl-L-ascorbicasidi akhoza kukhala stabilizer zothandiza p-hydroxyacetophenone njira.

Zotsatira za vitamini C ethyl ether pakhungu:

Kuletsa ntchito ya tyrosinase pochita Cu2 + ndikuletsa kupanga melanin;

Kuyeretsa kothandiza kwambiri komanso kuchotsa mawanga (2% mukawonjezeredwa);

Anti kutupa chifukwa kuwala, ali amphamvu antibacterial ndi odana ndi kutupa kwenikweni;

Kusintha khungu kuzimiririka luster, kupereka elasticity khungu;

Konzani ma cell a khungu ndikulimbikitsa kupanga kolajeni.
