Isingeniso Somkhiqizo
I-3-O-Ethyl Ascorbicacid iyi-derivative ewusizo kakhulu ye-vitamin C. Ayigcini nje ngokuqina ngamakhemikhali, iyi-derivative ye-vitamin C engashintshi umbala, futhi iyi-amphoteric ephilic ne-hydrophilic, eyandisa kakhulu ububanzi bayo bokusetshenziswa, ikakhulukazi kumakhemikhali ansuku zonke. I-3-O-ethyl ascorbic acid ether ingangena kalula e-dermis nge-stratum corneum. Ngemva kokungena emzimbeni, ibola kalula ngama-enzyme e-biological emzimbeni ukuze isebenzise imiphumela ye-biological ye-vitamin C.
I-3-O-Ethyl Ascorbicacid ingena ku-stratum corneum ngqo kuma-melanocyte engqimba eyisisekelo, ivimbele umsebenzi we-tyrosinase, ivimbele ukwakheka kwe-melanin, futhi inciphise i-melanin ibe yinto engenambala, ngaleyo ndlela yenze isikhumba sibe mhlophe ngempumelelo. Ngaphezu kwalokho, i-3-O-Ethyl Ascorbicacid ingangena ku-dermis futhi ihlanganyele ngqo ekwakhiweni kwe-collagen Chemicalbook protein ukulungisa umsebenzi weseli lesikhumba nokwandisa i-collagen, ngaleyo ndlela yenze isikhumba sibe sikhulu futhi sinwebeke, okwenza isikhumba sibe bushelelezi futhi sibushelelezi. I-3-O-Ethyl Ascorbicacid ingaba yi-stabilizer ewusizo yezixazululo ze-p-hydroxyacetophenone.
I-3-O-Ethyl ascorbic acid ether (i-vitamin C ethyl ether) iyisithako esincibilikayo ku-oyela namanzi, okuvumela abakhiqizi ukuthi basifake esigabeni samafutha noma esigabeni samanzi, noma basifake emazingeni okushisa aphezulu noma aphansi, okwenza kube lula ukusisebenzisa. Okubaluleke kakhulu, lokhu kuncibilika okubili kwenza kube lula ukungena ku-stratum corneum bese ungena ku-dermis ukuze kusebenze imiphumela yayo yemvelo, okuyinto ezinye izinhlobo ze-Chemicalbook vitamin C ezingenayo. Ingavimba ukwakheka kwe-melanin ngokuvimbela umsebenzi we-tyrosinase; inemiphumela yokususa amabala amhlophe kanye nama-freckle; imelana nokuvuvukala okubangelwa ukukhanya kwelanga futhi inemiphumela enamandla yokulwa namagciwane kanye nokuvuvukala; iphinde ithuthukise isikhumba esibuthakathaka nesibuthuntu, isinike ukukhanya, ukuguquguquka, kanye nokulungiswa. Ivuselela umsebenzi wamaseli esikhumba futhi ikhuthaze ukukhiqizwa kwe-collagen.

Umsebenzi Womkhiqizo
1. Umphumela wokwenza mhlophe: I-3-O-Ethyl Ascorbicacid ingavimbela umsebenzi we-tyrosinase esikhumbeni, ngaleyo ndlela ivimbele ukwakheka kwe-melanin futhi ifinyelele imiphumela yokwenza mhlophe. Ngesikhathi esifanayo, ingakhuthaza ukusebenza kwesikhumba futhi isize ukususa amabala e-pigment asele ekhona.
2. Umphumela we-Antioxidant: I-3-O-Ethyl Ascorbicacid inamandla amakhulu e-antioxidant, engasusa ama-free radicals futhi ivimbele isikhumba ekulimaleni yimisebe ye-ultraviolet kanye nokungcola kwemvelo. Ukusetshenziswa isikhathi eside kungathuthukisa ukukhazimula kwesikhumba kanye nokuqina kwaso futhi kulibazise ukuguga kwesikhumba.
3. Khuthaza ukwakheka kwe-collagen: I-3-O-Ethyl Ascorbicacid ingakhuthaza futhi ukwakheka kwe-collagen esikhumbeni, okubaluleke kakhulu ekugcineni ukuqina nokuqina kwesikhumba.
Isicelo Somkhiqizo
I-3-O-Ethyl Ascorbicacid isetshenziswa kabanzi emikhiqizweni yokunakekela isikhumba ekhanyisa futhi elwa nokuguga, njenge-lotion, ukhilimu, i-toner, i-mask, i-essence, njll. Isilinganiso esinconywayo ezimonyweni zokugcoba singama-0.5-3%.
