3-O-Ethyl-L-ascorbic acidIli ndi mphamvu ziwiri za mafuta ophilic ndipo ndi yokhazikika kwambiri pamankhwala. 3-O-Ethyl-L-ascorbic acid, cas nambala 86404-04-8, ili ndi mphamvu ya oleophilic komanso hydrophilic monga chochokera ku vitamini C, chomwe chimakulitsa ntchito yake, makamaka mu chemistry ya tsiku ndi tsiku.

Vitamini C wamba ndi wovuta kuyamwa ndi khungu ndipo alibe bioavailability yokwanira. Mphamvu ya 3-O-Ethyl L-ascorbic acid yothandiza polimbana ndi madzi komanso lipophilic zimapangitsa kuti zikhale zosavuta kulowa mu stratum corneum ndikulowa mu dermis. Pambuyo polowa pakhungu, 3-O-Ethyl L-Ascorbic acid imasungunuka mosavuta ndi ma enzymes achilengedwe kuti ikhale gawo la vitamini C, motero imawonjezera bioavailability yake.

Kuphatikiza apo, 3-O-Ethyl-L-ascorbic acid ndi vitamini C wodziwika bwino, womwe umasonyezanso kukhazikika kwakukulu kuti zitsimikizire kupezeka kwa VC, ndikukwaniritsadi zotsatira za kuyera ndi kufinya.

Katundu: 3-O-Ethyl-L-ascorbic acid ndi ufa woyera kapena woyera wa kristalo. Ndi imodzi mwa zinthu zabwino kwambiri zomwe zimapezeka mu vitamini C mpaka pano. Sikuti imangokhala yokhazikika pa mankhwala okha, komanso imachokera ku ascorbic acid yomwe siimasintha mtundu ikalowa pakhungu. Imasinthidwa mofanana ndi vitamini C m'thupi, motero imagwira ntchito bwino ndi ascorbic acid.

Njira Yogwirira Ntchito: 3-O-Ethyl-L-ascorbic acid imaletsa ntchito ya tyrosinase ndi kupangika kwa melanin mwa kufika pa basal layer kudzera mu stratum corneum ya khungu, kuchepetsa melanin kukhala yopanda mtundu, yothandiza kuyeretsa ndi kuchotsa madontho. 3-O-Ethyl-L-ascorbic acid imathanso kutenga nawo mbali mwachindunji pakupanga collagen ikalowa mu dermis, zomwe zimapangitsa kuti collagen iwonjezere, motero zimapangitsa khungu kukhala lodzaza komanso lotanuka.

Ntchito zazikulu:

(1) Kuletsa ntchito ya tyrosinase ndikuletsa kupanga melanin; Kuchepetsa melanin, kuyeretsa mawanga ndi kuyeretsa khungu.

(2) Mphamvu yamphamvu yoteteza ku ma antioxidants, kuchotsa bwino ma free radicals.

(3) Kukhazikika bwino, kukana kuwala, kukana kutentha, kukana asidi ndi alkali, kukana kukhuthala kwa mpweya. Kupezeka kwa bioavailability yambiri, mafuta ophikira madzi, komanso kuyamwa khungu mosavuta.

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

(5) Kulimbikitsa kupanga kolajeni ndikuwonjezera kusinthasintha kwa khungu.

3-O-Ethyl-L-ascorbic acidIli ndi ntchito yokonzanso collagen (kuphatikizapo kukonza kapangidwe ka collagen ndi kapangidwe kake), zomwe zingathandize kupangidwa kwa maselo a khungu ndi kapangidwe ka collagen malinga ndi chiŵerengero cha maselo a khungu ndi momwe collagen imagwiritsidwira ntchito, kuti khungu likhale lowala komanso losalala. Vitamini C ethyl ether imagwiritsidwa ntchito kwambiri poyeretsa ma freckle ndi zinthu zoteteza kukalamba pakhungu, monga lotion, cream, toner, mask, essence ndi zina zotero.

Kugwiritsa ntchito mankhwala:

Mankhwalawa amagwiritsidwa ntchito popanga zinthu zoyera, zinthu zoletsa ukalamba, madzi, gel, essence, lotion, kirimu wosamalira khungu ndi zina zotero.

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

[Ntchito yovomerezeka] Ndi bwino kugwiritsa ntchito pansi pa mikhalidwe ya PH3.0-6.0, ndipo kuyera ndi kuoneka kwa ma freckle ndiye njira yabwino kwambiri.

3-O-ethyl-L-ascorbicasidi angakhale chokhazikika chothandiza pa mayankho a p-hydroxyacetophenone.

Zotsatira za vitamini C ethyl ether pakhungu:

Kuletsa ntchito ya tyrosinase mwa kuchitapo kanthu pa Cu2+ ndikuletsa kupanga melanin;

Kuyeretsa bwino komanso kuchotsa madontho a khungu (2% akawonjezeredwa);

Kuletsa kutupa komwe kumachitika chifukwa cha kuwala, kumakhala ndi mphamvu yolimbana ndi mabakiteriya komanso kutupa;

Kupangitsa khungu kukhala losalala, kupangitsa kuti likhale lolimba;

Konzani ntchito ya maselo a khungu ndikulimbikitsa kupanga collagen.
