Ukusetshenziswa
I-Ethyl ascorbic acidiyi-derivative ewusizo kakhulu ye-vitamin C. Ayigcini nje ngokuqina ngamakhemikhali, njengoba iyi-derivative ye-vitamin C engashintshi umbala, kodwa futhi iyinto e-amphiphilic enezakhiwo ze-lipophilic kanye ne-hydrophilic, okwandisa kakhulu ububanzi bokusetshenziswa kwayo, ikakhulukazi kumakhemikhali asetshenziswa nsuku zonke. I-3-O-Ethyl ascorbic acid ether ingangena kalula ku-stratum corneum futhi ifinyelele ku-dermis. Uma isingene emzimbeni, ibola kalula ngama-enzyme e-biological emzimbeni, ngaleyo ndlela isebenzisa imisebenzi ye-biological ye-vitamin C.
I-Ethyl ascorbic acid (i-VC ethyl ether)iyi-derivative ye-vitamin C e-amphiphilic ephinde ibe yi-lipophilic kanye ne-hydrophilic. Ayigcini nje ngokugcina umsebenzi we-redox we-vitamin C kodwa futhi izinzile kakhulu. Iyi-derivative ye-vitamin C engashintshi umbala. Ngaphezu kwalokho, njengoba iyi-amphiphilic, kulula kakhulu ukuyisebenzisa ekwakhiweni. Ngaphezu kwalokho, ingangena kalula ku-stratum corneum futhi ingene ku-dermis. Uma isingene esikhumbeni, ibola kalula ngama-enzyme e-biological ukuze isebenzise imisebenzi ye-vitamin C, ngaleyo ndlela ithuthukise ukutholakala kwayo.
i-ether ye-3-O-Ethyl ascorbic acid (i-ethyl ascorbic acid)kuyinto encibilikayo kokubili ku-oyili nasemanzini. Lokhu kuvumela abakhiqizi ukuthi bayifake esigabeni samafutha noma esigabeni samanzi, futhi ingafakwa emazingeni okushisa aphezulu noma aphansi, okwenza kube lula kakhulu ukuyisebenzisa. Okubaluleke kakhulu, lesi sici esithinta amaphiko siyenza ikwazi ukungena kalula ku-stratum corneum futhi ingene ku-dermis, ngaleyo ndlela isebenzise imiphumela yayo yemvelo, engenakwenzeka kwezinye izinto ezithathwe ku-vitamin C. Ingavimbela umsebenzi we-tyrosinase ukuvimba ukwakheka kwe-melanin; inemiphumela yokususa amabala amhlophe kanye nama-freckle (uma ingeziwe ku-2%); ingamelana nokuvuvukala okubangelwa ukukhanya kwelanga futhi inemiphumela enamandla yokulwa namagciwane kanye nokuvuvukala; ngesikhathi esifanayo, ingathuthukisa isikhumba esibuthakathaka nesingenakukhanya, inike isikhumba ukukhanya nokunwebeka, ilungise umsebenzi wamaseli esikhumba, futhi ikhuthaze ukukhiqizwa kwe-collagen.
Ukupakisha Nokuthumela
25KG/Isigubhu noma ngokwezidingo zamakhasimende.
Ingeyasesigabeni sesi-8 sezimpahla eziyingozi futhi ingathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
