3-O-Ethyl-L-ascorbic acid e molemo bakeng sa eng?

3-O-Ethyl-L-ascorbic acidE na le thepa e habeli ea oli e hydrophilic 'me ka lik'hemik'hale e tsitsitse haholo. 3-O-Ethyl-L-ascorbic acid, cas nomoro 86404-04-8, e na le thepa ea oleophilic le hydrophilic e le derivative ea vithamine C, e atolosang boholo ba ts'ebeliso ea eona, haholo-holo k'hemistri ea letsatsi le letsatsi.

3-O-Ethyl-L-ascorbic-acid

Vithamine C e tloaelehileng e thata ho monngoa ke letlalo 'me e na le bioavailability e tlase. Matla a hydrophilic le lipophilic a 3-O-Ethyl L-ascorbic acid a etsa hore ho be bonolo ho kenella ka har'a stratum corneum le ho kena ka har'a dermis. Kamora ho kena letlalong, 3-O-Ethyl L-Ascorbic acid e bola habonolo ke li-enzyme tsa baeloji ho bapala karolo ea vithamine C, ka hona e ntlafatsa bioavailability ea eona.

Ho phaella moo, 3-O-Ethyl-L-ascorbic acid ke vithamine C e tloaelehileng haholo, e boetse e bontša botsitso bo phahameng ho netefatsa hore VC e fumaneha, 'me e hlile e finyella phello ea ho soeufatsa le ho soeufala ha letlalo.

Matlotlo: 3-O-Ethyl-L-ascorbic acid ke phofo e tšoeu kapa e tšoeu e kristale ka ponahalo. Ke e 'ngoe ea lihlahisoa tse ntle ka ho fetisisa tsa vithamine C ho fihlela joale. Hase feela hore e tsitsitse ka lik'hemik'hale, empa hape ke sehlahisoa sa ascorbic acid se sa fetoheng 'mala habonolo ka mor'a ho kena letlalong. E fetoloa ka tsela e tšoanang le ea vithamine C 'meleng, ka hona e etsa hore ascorbic acid e be le phello e betere.

3-O-Ethyl-L-ascorbic-acid-e sebelisitsoeng

Mokhoa oa ts'ebetso: 3-O-Ethyl-L-ascorbic acid e thibela ts'ebetso ea tyrosinase le ho thehoa ha melanin ka ho fihla lera la basal ka har'a stratum corneum ea letlalo, e fokotsa melanin ho ba e se nang 'mala, e sebetsang hantle ho soeufatseng le ho tlosa matheba. 3-O-Ethyl-L-ascorbic acid e ka boela ea nka karolo ka kotloloho tlhahisong ea collagen kamora ho kena dermis, e leng se eketsang collagen, ka hona e etsa hore letlalo le tlale le be bonolo.

Mesebetsi e ka sehloohong:

(1) Ho thibela ts'ebetso ea tyrosinase le ho thibela ho thehoa ha melanin; Ho fokotsa melanin, ho khantša matheba le ho soeufatsa letlalo.

(2) Tšusumetso e matla ea antioxidant, ho tlosoa ha li-free radical ka katleho.

(3) Ho tsitsa ho hotle, ho hanyetsa khanya, ho hanyetsa mocheso, ho hanyetsa asiti le alkali, ho hanyetsa moea o oxidation. Ho fumaneha ha bioavailability e phahameng, oli e phelang metsing, ho monya letlalo habonolo.

(4) Thibela ho ruruha ha letlalo ho bakoang ke khanya ea letsatsi.

(5) Ho kgothaletsa tlhahiso ya collagen le ho eketsa ho tenyetseha ha letlalo.

3-O-Ethyl-L-ascorbic acide na le mosebetsi oa ho lokisa collagen (ho kenyeletsoa le ho lokisa sebopeho le tlhahiso ea collagen), e leng se ka khothalletsang ho thehoa ha lisele tsa letlalo le tlhahiso ea collagen ho latela karolelano ea lisele tsa letlalo le tšebeliso ea collagen, e le ho etsa hore letlalo le benye le benye. Vithamine C ethyl ether e sebelisoa haholo lihlahisoa tsa tlhokomelo ea letlalo tse soeufatsang matheba le tse thibelang botsofali, tse kang lotion, tranelate, toner, mask, essence le tse ling.

Tšebeliso ea 3-O-Ethyl-L-ascorbic acid

Tšebeliso ea sehlahisoa:

Sehlahisoa sena se sebelisoa lihlahisoa tsa ho soeufatsa, lihlahisoa tsa ho thibela botsofali, metsi, gel, essence, lotion, tranelate ea tlhokomelo ea letlalo le tse ling.

[Tekanyo e kgothaletswang] 0.1-2.0%, e loketse dihlahiswa tsa ho soeufatsa le ho tlosa matheba, ho tlosa matheba le dihlahiswa tse thibelang botsofali.

[Ts'ebetso e khothaletsoang] Ho molemo ho e sebelisa tlas'a maemo a PH3.0-6.0, 'me phello ea ho soeufatsa le ho fifala ha matheba ke eona e molemohali.

3-O-ethyl-L-ascorbicasiti e ka ba sesebelisoa se thusang ho tsitsisa ditharollo tsa p-hydroxyacetophenone.

Litlamorao tsa vithamine C ethyl ether letlalong:

Ho thibela ts'ebetso ea tyrosinase ka ho sebetsa ho Cu2+ le ho thibela ho thehoa ha melanin;

Ho tlosa matheba le ho soeufatsa letlalo hantle haholo (2% ha e eketsoa);

Thibela ho ruruha ho bakoang ke leseli, e na le phello e matla ea antibacterial le anti-inflammatory;

Ntlafatsa khanya e lerootho ea letlalo, e fe letlalo ho tenyetseha;

Lokisa tšebetso ea lisele tsa letlalo le ho khothaletsa tlhahiso ea collagen.
