I-3-O-Ethyl-L-ascorbic acidinezakhiwo ezimbili zamafutha aphilizayo futhi izinzile kakhulu ngamakhemikhali. I-3-O-Ethyl-L-ascorbic acid, inombolo ye-cas 86404-04-8, inempahla ye-oleophilic ne-hydrophilic njenge-derivative ye-vitamin C, eyandisa ububanzi bayo bokusetshenziswa, ikakhulukazi kumakhemikhali ansuku zonke.

I-vitamin C evamile kunzima ukuyimunca esikhumbeni futhi ayinayo i-bioavailability ephansi. Izakhiwo ze-3-O-Ethyl L-ascorbic acid ezithinta amanzi kanye ne-lipophilic zenza kube lula ukungena ku-stratum corneum bese kungena ku-dermis. Ngemva kokungena esikhumbeni, i-3-O-Ethyl L-Ascorbic acid ibola kalula ngama-enzyme e-biological ukuze idlale indima ye-vitamin C, ngaleyo ndlela ithuthukise i-bioavailability yayo.

Ngaphezu kwalokho, i-3-O-Ethyl-L-ascorbic acid iyi-vitamin C evamile, ephinde ibonise ukuzinza okuphezulu ukuqinisekisa ukutholakala kwe-VC, futhi ifeze ngempela umphumela wokwenza mhlophe kanye nokuqhekeka kwesikhumba.

Izakhiwo: I-3-O-Ethyl-L-ascorbic acid iyimpuphu emhlophe noma emhlophe ecwebezelayo ebukekayo. Ingenye yezinto eziphuma ku-vitamin C ezinhle kakhulu kuze kube manje. Ayigcini nje ngokuqina ngamakhemikhali, kodwa futhi iyi-ascorbic acid derivative engashintshi umbala kalula ngemva kokungena esikhumbeni. Iguqulwa ngendlela efanayo ne-vitamin C emzimbeni, ngaleyo ndlela ibe nomphumela ongcono we-ascorbic acid.

Indlela yokusebenza: I-3-O-Ethyl-L-ascorbic acid ivimbela umsebenzi we-tyrosinase kanye nokwakheka kwe-melanin ngokufinyelela ungqimba oluyisisekelo nge-stratum corneum yesikhumba, inciphisa i-melanin ibe yinto engenambala, iyasebenza ekwenzeni mhlophe futhi isuse amabala. I-3-O-Ethyl-L-ascorbic acid nayo ingabamba iqhaza ngqo ekwakhiweni kwe-collagen ngemva kokungena ku-dermis, okwandisa i-collagen, ngaleyo ndlela yenze isikhumba sigcwale futhi sinwebeke.

Imisebenzi eyinhloko:

(1) Ukuvimbela umsebenzi we-tyrosinase nokuvimbela ukwakheka kwe-melanin; Ukunciphisa i-melanin, kukhanyisa amabala futhi kubenze babe mhlophe.

(2) Umphumela onamandla we-antioxidant, ukususwa okuphumelelayo kwama-free radicals.

(3) Ukuqina okuhle, ukumelana nokukhanya, ukumelana nokushisa, ukumelana ne-asidi ne-alkali, ukumelana nokushiswa komoya. Ukutholakala okuphezulu kwe-bioavailability, uwoyela othanda amanzi, ukumuncwa kwesikhumba kalula.

(4) Vimbela ukuvuvukala kwesikhumba okubangelwa ukukhanya kwelanga.

(5) Khuthaza ukukhiqizwa kwe-collagen futhi kwandise ukunwebeka kwesikhumba.

I-3-O-Ethyl-L-ascorbic acidinomsebenzi wokulungisa i-collagen (kufaka phakathi ukulungisa ukwakheka kwe-collagen kanye nokwakheka kwayo), okungakhuthaza ukwakheka kwamaseli esikhumba kanye nokwakheka kwe-collagen ngokwesilinganiso samaseli esikhumba kanye nokusetshenziswa kwe-collagen, ukuze isikhumba sikhanye futhi sinwebeke. I-Vitamin C ethyl ether isetshenziswa kabanzi emikhiqizweni yokunakekela isikhumba ekhanyisa amabala kanye nemithi yokulwa nokuguga, njenge-lotion, ukhilimu, i-toner, imaski, i-essence njalo njalo.

Ukusetshenziswa komkhiqizo:

Lo mkhiqizo usetshenziswa emikhiqizweni yokwenza mhlophe, imikhiqizo yokulwa nokuguga, amanzi, ijeli, i-essence, i-lotion, ukhilimu wokunakekela isikhumba njalo njalo.

[Isilinganiso esinconyiwe] 0.1-2.0%, efanelekile emikhiqizweni yokususa amabala amhlophe, ukususa imibimbi kanye nemikhiqizo yokulwa nokuguga.

[Ukusebenza Okunconywayo] Kungcono ukuyisebenzisa ngaphansi kwezimo ze-PH3.0-6.0, futhi umphumela wokuba mhlophe kanye nama-freckle yiwona ongcono kakhulu.

I-3-O-ethyl-L-ascorbici-asidi ingaba yisiqinisi esiwusizo sezixazululo ze-p-hydroxyacetophenone.

Imiphumela ye-vitamin C ethyl ether esikhumbeni:

Ukuvimbela umsebenzi we-tyrosinase ngokusebenza ku-Cu2+ nokuvimbela ukwakheka kwe-melanin;

Ukususa amabala amhlophe kahle kakhulu (2% uma kungeziwe);

Ukulwa nokuvuvukala okubangelwa ukukhanya, kunomphumela oqinile wokulwa namagciwane kanye nokuvuvukala;

Thuthukisa ukukhazimula kwesikhumba okubuthuntu, kwenze isikhumba sithambe;

Lungisa umsebenzi wamaseli esikhumba futhi ukhuthaze ukukhiqizwa kwe-collagen.
