Ibanga Lobuhle 98% Tetrahexyldecyl Ascorbate (VC-IP) CAS 183476-82-6
I-Tetrahexyldecyl ascorbate uhlobo lwevithamini C olushintshiwe ukuze luncibilike kakhulu kuma-lipid. Lokhu kuguqulwa kuyivumela ukuthi ingene kangcono esikhumbeni. Enomsebenzi wokulwa ne-oxidant, ivimbela i-lipid peroxidation. Ukusetshenziswa ngaphandle kunganciphisa imiphumela elimazayo yokuchayeka kwe-UV. Izifundo zikhombisile ukuthi ikhuthaza ukukhiqizwa kwe-collagen kanye nokucacisa nokukhanyisa isikhumba ngokuvimbela i-melanogenesis (ukukhiqizwa kwe-pigment) ngaleyo ndlela ikhuthaze ithoni yesikhumba elinganayo. Ngokungafani ne-ascorbic acid, ngeke ikhiphe noma icasule isikhumba.
Inkinga ngezinhlobo eziningi zevithamini C ezitholakala endaweni engaphandle ukuthi ziyancibilika emanzini futhi azikwazi ukudlula esivimbelweni sesikhumba esicebile ngamafutha ukuze zifinyelele esikhumbeni lapho zingaba nezinzuzo ezinkulu khona. I-Tetrahexyldecyl ascorbate iyakwazi ukungena ngempumelelo esikhumbeni bese ithuthela ongqimbeni olungaphansi olubizwa ngokuthi i-dermis. Kusesikhumbeni lapho kwakheka khona i-collagen, iphrotheni enika isikhumba ukuqina kwaso kobusha kanye nekhono lokumelana nemibimbi.
1. Izifundo zibonisa ukuthi i-ascorbyl tetraisopalmitate izohlala emangqamuzaneni esikhumba isikhathi eside ngokuphindwe kangamashumi amane kuya kwamashumi ayisishiyagalombili kune-ascorbic acid futhi izoba nomphumela ophindwe kane；
2. I-Ascorbyl Tetraisopalmitate ingavimbela umsebenzi we-tyrosinase wangaphakathi kweseli kanye nokukhiqizwa kwe-melanin; Izinto zokusetshenziswa zobuhle ezisezingeni eliphezulu i-Ascorbyl Tetraisopalmitate;
3. I-Ascorbyl Tetraisopalmitate inganciphisa umonakalo weseli/i-DNA obangelwa yi-UV (ilwa ne-UV/ilwa nokucindezeleka) ； Izinto zokuhlobisa ezisezingeni eliphezulu i-Ascorbyl Tetraisopalmitate;
4. I-Ascorbyl Tetraisopalmitate ingavimbela i-lipid peroxidation kanye nokuguga kwesikhumba；
5. I-Ascorbyl Tetraisopalmitate inciphisa ukulahleka kwamanzi e-trans-epidermal；
6. I-Ascorbyl Tetraisopalmitate ithuthukisa ngokubonakalayo ukuthungwa kanye nemibimbi.
