I-3-O-Ethyl-L-ascorbic acidinezinto ezimbili zikawoyela we-hydrophilic futhi izinzile ngokwedlulele ngokwamakhemikhali. I-3-O-Ethyl-L-ascorbic acid, inombolo ye-cas 86404-04-8, inendawo ye-oleophilic ne-hydrophilic njenge-derivative ye-vitamin C, eyandisa ububanzi bayo bokusebenza, ikakhulukazi kumakhemikhali wansuku zonke.

Ivithamini C evamile inzima ukumuncwa isikhumba futhi ine-bioavailability ephansi. Izakhiwo ze-hydrophilic ne-lipophilic ze-3-O-Ethyl L-ascorbic acid zenza kube lula ukungena ku-stratum corneum bese ungena edermis. Ngemva kokungena esikhumbeni, i-3-O-Ethyl L-Ascorbic acid ichithwa kalula ngama-enzyme ephilayo ukuze idlale indima ye-vitamin C, ngaleyo ndlela ithuthukise i-bioavailability yayo.

Ngaphezu kwalokho, i-3-O-Ethyl-L-ascorbic acid iyivithamini C evamile, ephinde ibonise ukuzinza okuphezulu ukuze kuqinisekiswe ukutholakala kwe-VC, futhi kuzuzwe ngempela umphumela wokuba mhlophe kanye ne-freckling.

Izakhiwo: I-3-O-Ethyl-L-ascorbic acid iyimpushana emhlophe emhlophe noma emhlophe ngokubukeka. Ingenye yezinto ezinhle kakhulu eziphuma ku-vitamin C kuze kube manje. Akukona nje ukuzinza kwamakhemikhali, kodwa futhi i-ascorbic acid derivative engaguquki kalula ngemva kokungena esikhumbeni. I-metabolized ngendlela efanayo ne-vitamin C emzimbeni, ngaleyo ndlela yenza umphumela ongcono we-ascorbic acid.

Indlela yokusebenza: I-3-O-Ethyl-L-ascorbic acid ivimbela umsebenzi we-tyrosinase kanye nokwakheka kwe-melanin ngokufinyelela ungqimba lwe-basal ngokusebenzisa i-stratum corneum yesikhumba, inciphisa i-melanin ingabi mbala, isebenze emhlophe futhi isuse ama-freckles. I-3-O-Ethyl-L-ascorbic acid nayo ingabamba iqhaza ngokuqondile ekuhlanganiseni kwe-collagen ngemva kokungena ku-dermis, okwandisa i-collagen, ngaleyo ndlela yenza isikhumba sigcwale futhi sinwebeka.

Imisebenzi esemqoka:

(1) Ukuvimbela umsebenzi we-tyrosinase nokuvimbela ukwakheka kwe-melanin; Yehlisa i-melanin, khanyisa amabala futhi wenze mhlophe.

(2) Umphumela onamandla we-antioxidant, ukususwa okusebenzayo kwama-radicals mahhala.

(3) Ukuzinza okuhle, ukumelana nokukhanya, ukumelana nokushisa, ukumelana ne-asidi ne-alkali, ukumelana ne-air oxidation. I-bioavailability ephezulu, uwoyela we-hydrophilic, ukumuncwa kalula kwesikhumba.

(4) Vimbela ukuvuvukala kwesikhumba okubangelwa ukukhanya kwelanga.

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

I-3-O-Ethyl-L-ascorbic acidinomsebenzi wokulungisa i-collagen (okuhlanganisa ukulungisa ukwakheka kwe-collagen kanye nokuhlanganiswa), okungakhuthaza ukwakheka kwamangqamuzana esikhumba kanye nokuhlanganiswa kwe-collagen ngokuvumelana nesilinganiso samangqamuzana esikhumba kanye nokusetshenziswa kwe-collagen, ukuze wenze isikhumba sikhanye futhi sinwebeka. I-Vitamin C ethyl ether isetshenziswa kakhulu emikhiqizweni yokunakekelwa kwesikhumba emhlophe kanye ne-anti-aging, efana ne-lotion, ukhilimu, i-toner, imaski, i-essence nokunye.

Ukusetshenziswa komkhiqizo:

Lo mkhiqizo usetshenziswa emikhiqizweni emhlophe, imikhiqizo elwa nokuguga, amanzi, ijeli, i-essence, i-lotion, ukhilimu wokunakekelwa kwesikhumba nokunye.

[Umthamo onconyiwe] 0.1-2.0%, ulungele imikhiqizo emhlophe nekhipha amabala, ukususwa kwemibimbi kanye nemikhiqizo elwa nokuguga.

[Ukusebenza okunconyiwe] Kungcono ukusebenzisa ngaphansi kwezimo ze-PH3.0-6.0, futhi umphumela omhlophe kanye ne-freckle uhamba phambili.

3-O-ethyl-L-ascorbici-asidi ingase ibe isizinzisi esiwusizo sezixazululo ze-p-hydroxyacetophenone.

Imiphumela ye-vitamin C ethyl ether esikhumbeni:

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

Ukwenza kube mhlophe okusebenzayo kakhulu nokususwa kwamafreckle (2% uma kungeziwe);

Ukulwa nokuvuvukala okubangelwa ukukhanya, kunomphumela oqinile we-antibacterial and anti-inflammatory;

Thuthukisa ukucwebezela kwesikhumba, unikeze ukunwebeka kwesikhumba;

Lungisa umsebenzi wamangqamuzana esikhumba futhi ukhuthaze ukukhiqizwa kwe-collagen.
