1. Taw qhia
Vitamin C muaj ntau lub luag haujlwm ua cov khoom siv kom zoo nkauj, nrog rau cov tawv nqaij ua kom pom kev, txhawb nqa collagen synthesis thiab inhibiting lipid peroxidation. Txawm li cas los xij, vitamin C yog qhov ua rau oxidative discoloration, ua rau nws nyuaj rau siv hauv tshuaj pleev ib ce. Yog li ntawd, VC derivatives ruaj khov dua tau tsim. Ascorbyl Tetraisopalmitate yog vitamin C derivative, nws tseem hu ua fat-soluble vitamin C, esterified vitamin C. Nws yog qhov ruaj khov tshaj plaws ntawm tag nrho cov vitamin C derivatives.
2. Lub luag haujlwm tseem ceeb
2.1 Ascorbyl Tetraisopalmitate yog qhov ruaj khov dua li cov vitamin C.
Yog vim li cas vim li cas cov qauv vitamin C muaj cov khoom zoo antioxidant yog tias nws muaj cov qauv [dienol], uas ua rau nws tsis ruaj khov thiab yooj yim hloov xim.
Raws li rau VC-IP, ob lub ultra-ntev isopalmitic acid cov qauv yog esterified nrog cov hydroxyl pawg saum toj no, thiab ntau exaggeratedly, lwm ob "tsis muaj txim" hydroxyl pawg kuj tshwm sim ua ke, ua "octopus" qauv.
Vim li no, VC-IP tsis muaj cov tshuaj tiv thaiv antioxidant hauv vitro (nws tsuas yog ua haujlwm thaum nws nkag mus rau ntawm daim tawv nqaij). Nws tuaj yeem khaws cia hauv chav sov li 6 lub hlis, thiab nws cov haujlwm tuaj yeem khaws cia rau ntau dua 85 feem pua.
Txawm hais tias nws muab tso rau hauv cov mis, tsuav yog pH tsawg dua 6, qhov kub thiab txias tsis muaj qhov cuam tshuam. Txawm li cas los xij cov khoom koj ua, txawm tias nws yog cov tshuaj pleev ib ce, cov ntsiab lus lossis qab zib, qhov kev hloov pauv tau zoo heev, zoo dua li cov qauv vitamin C.
2.2 VC IP muaj qhov zoo tshaj plaws transdermal haum
Ntau qhov teeb meem ntawm vitamin C derivatives feem ntau tsis tuaj ntawm kev ruaj ntseg, tab sis lawv cov khoom siv transdermal thiab seb lawv puas tuaj yeem hloov mus rau hauv cov vitamin C tiag tiag hauv daim tawv nqaij, txwv tsis pub, txawm tias lawv ruaj khov, lawv tuaj yeem tsuas yog kho kom zoo nkauj.
Raws li kev nkag mus ntawm daim tawv nqaij muaj kev txhawj xeeb, tus qauv vitamin C tsis ua haujlwm zoo vim nws yog cov dej-soluble tshuaj, thiab cell membranes feem ntau yog lipophilic.
Raws li cov roj-soluble VC-IP, txawm hais tias nws loj, nws muaj cov lipophilic zoo dua vim yog qhov sib ntxiv ntawm pawg palmitic acid.
2.3 Nws muaj kev tiv thaiv oxidation
Hauv kev sim hauv vitro cell, xws li kev sim ua kom rov tsim dua collagen, kev sim DNA tiv thaiv, thiab lwm yam, kev ua haujlwm ntawm VC-IP yog qhov zoo heev, tsis muaj tsawg dua vitamin C.
Hauv qee qhov ntsuas, nws tseem tshaj vitamin C, uas muaj ntau yam ua rau nws cov khoom siv transdermal.
3. Cov ntawv thov
Ascorbyl Tetraisopalmitate feem ntau yog siv rau hauv cov tshuaj pleev ib ce.
Daim ntawv thov:
3.1. Qhov pH ntau thaum lub sij hawm tsim yog tsim kom tsis txhob siab tshaj 6.0.
3.2. Nws raug nquahu kom siv cov tshuaj chelates hauv kev tsim tawm vim tias cov tshuaj chelate muaj txiaj ntsig zoo hauv kev tiv thaiv kom tsis muaj xim.
3.3. Txij li thaum sib cuag nrog dej yuav ua rau oxidation ntawm ascorbyl tetraisopalmitate, ntxiv ib tug surfactant nrog ntev-chain polyoxyethylene kom stabilize lub system thiab ntxiv dag zog rau lub interface zaj duab xis.
3.4. Tsis txhob raug tshav kub ntev.
4. Flow Chart
2-Hexyldecanal reacts nrog L-ascorbic acid ncaj qha nyob rau hauv qhov kev txiav txim ntawm catalyst thiab oxidant los tsim ascorbyl tetraisopalmitate; Tom qab tshem tawm, ntxuav, ziab, concentration, purification thiab lwm yam kev kho mob tom qab, ascorbyl tetraisopalmitate tau txais.
