3-O-Ethyl-L-ascorbic acide na le likarolo tse peli tsa oli ea hydrophilic mme e tsitsitse haholo ka lik'hemik'hale. 3-O-Ethyl-L-ascorbic acid, cas number 86404-04-8, e na le thepa ea oleophilic le hydrophilic e le derivative ea vithamine C, e atolosang sebaka sa eona sa kopo, haholo-holo k'hemistri ea letsatsi le letsatsi.

Vithamine C e tloaelehileng e thata ho monngoa ke letlalo mme e na le bioavailability e tlase. Thepa ea hydrophilic le lipophilic ea 3-O-Ethyl L-ascorbic acid e etsa hore ho be bonolo ho kenella ka har'a stratum corneum le ho kena dermis. Ka mor'a ho kena letlalong, 3-O-Ethyl L-Ascorbic acid e senyeha habonolo ke li-enzyme tsa likokoana-hloko ho phetha karolo ea vithamine C, kahoo e ntlafatsa bioavailability ea eona.

Ho phaella moo, 3-O-Ethyl-L-ascorbic acid e batla e tloaelehile vithamine C, eo hape e bontšang botsitso bo phahameng ho netefatsa hore ho na le VC, 'me e hlile e finyella phello ea ho soeufala le ho fofa.

Thepa: 3-O-Ethyl-L-ascorbic acid ke phofo e tšoeu kapa e tšoeu ea kristale ka ponahalo. Ke e 'ngoe ea lihlahisoa tse ntle ka ho fetisisa tsa vithamine C ho fihlela joale. Ha e na lik'hemik'hale tse tsitsitseng feela, empa hape ke motsoako oa ascorbic acid o sa fetoheng habonolo ka mor'a ho kena letlalong. E entsoe ka mokhoa o ts'oanang le vithamine C 'meleng, kahoo e fana ka phello e ntle ea ascorbic acid.

Mokhoa oa ts'ebetso: 3-O-Ethyl-L-ascorbic acid e thibela ts'ebetso ea tyrosinase le ho thehoa ha melanin ka ho fihla karolong ea basal ka stratum corneum ea letlalo, e fokotsa melanin hore e se na mebala, e sebetsang ka ho soeufala le ho tlosa li-freckles. 3-O-Ethyl-L-ascorbic acid e ka boela ea kenya letsoho ka ho toba tlhahisong ea collagen ka mor'a hore e kene ka har'a dermis, e leng ho eketsang collagen, ka tsela eo ho etsa hore letlalo le tlale le ho reketla.

Mesebetsi ea mantlha:

(1) Ho thibela mosebetsi oa tyrosinase le ho thibela ho thehoa ha melanin; Fokotsa melanin, fokotsa matheba le ho soeufatsa.

(2) Tšusumetso e matla ea antioxidant, ho tlosoa ka katleho ha li-radicals tsa mahala.

(3) Botsitso bo botle, ho hanyetsa khanya, ho hanyetsa mocheso, ho hanyetsa acid le alkali, ho hanyetsa moea oxidation. Bioavailability e phahameng, oli ea hydrophilic, ho monya ha bonolo ha letlalo.

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

(5) Khothalletsa tlhahiso ea collagen le ho eketsa elasticity ea letlalo.

3-O-Ethyl-L-ascorbic acide na le mosebetsi oa ho lokisa collagen (ho kenyeletsoa ho lokisa sebopeho sa collagen le synthesis), e ka khothalletsang ho thehoa ha lisele tsa letlalo le motsoako oa collagen ho ea ka karo-karolelano ea lisele tsa letlalo le tšebeliso ea collagen, e le ho etsa hore letlalo le benye le rekere. Vithamine C ethyl ether e sebelisoa haholo lihlahisoa tsa tlhokomelo ea letlalo tse soeufatsang le tse thibelang botsofali, joalo ka lotion, tranelate, toner, mask, essence joalo-joalo.

Tšebeliso ea lihlahisoa:

Sehlahisoa sena se sebelisoa lihlahisoa tse tšoeu, lihlahisoa tse thibelang botsofali, metsi, gel, essence, lotion, tranelate ea tlhokomelo ea letlalo joalo-joalo.

[Tekanyetso e khothalelitsoeng] 0.1-2.0%, e loketseng lihlahisoa tse soeufatsang le tse tlositsoeng matheba, ho tlosoa ha makhopho le lihlahisoa tse thibelang botsofali.

[Ts'ebetso e khothalelitsoeng] Ho molemo ho sebelisa tlasa maemo a PH3.0-6.0, 'me phello e tšoeu le ea freckle ke eona e ntle ka ho fetisisa.

3-O-ethyl-L-ascorbicacid e ka 'na ea e-ba ntho e tsitsitseng e sebetsang bakeng sa tharollo ea p-hydroxyacetophenone.

Liphello tsa vithamine C ethyl ether letlalong:

Ho thibela mosebetsi oa tyrosinase ka ho sebetsa ho Cu2 + le ho thibela ho thehoa ha melanin;

Ho soeufala haholo le ho tlosoa ha matheba (2% ha ho kenyelletsoa);

Anti-inflammatory e bakoang ke leseli, e na le phello e matla ea antibacterial le anti-inflammatory;

Ntlafatsa letlalo le khanyang le khanyang, le fane ka elasticity ea letlalo;

Lokisa ts'ebetso ea lisele tsa letlalo le ho khothaletsa tlhahiso ea collagen.
