Ethyl ascorbic acid
Ethyl ascorbic acid,3-O-Ethyl Ascorbic Acid, mofuta oa ethylated vithamine C, ke ntho e ntle ka ho fetisisa ea ho hloekisa letlalo, e thibela mosebetsi oa Tyrosinase ka ho sebetsa ka Cu2 + 'me e thibela ho qaptjoa ha melanin. acid.E boetse e bontša botsitso bo botle haholo mefuteng eohle ea litlolo tsa litlolo.
Ethyl Ascorbic Acid e kenella ka har'a letlalo moo e entsoeng ka metabolized ho ascorbic acid.Ka lebaka la ts'ebetso ena, isore ea eona e sebetsang hantle ho feta ea ascorbic acid e hloekileng. E sa halefiseng letlalo le mahlo.

Vithamine C
Matsatsing ana a fapanenglihlahisoa tsa vithamine C li sebelisoa litlolo bakeng sa tšebeliso ea ka ntle . Vithamine C e hloekileng, ascorbic acid kapa e boetse e bitsoa L-ascorbic acid (ascorbic acid) e na le phello e tobileng ka ho fetisisa.Ho fapana le mefuta e meng e fapaneng, ha ho hlokahale hore e fetohe pele ka mokhoa o sebetsang. Liphuputso li bontša hore vithamine C e tšehetsa motsoako oa collagen le ho loantša li-radicals tsa mahala. E boetse e sebetsa khahlanong le makhopho le matheba a lilemo ka ho thibela tyrosinase. Leha ho le joalo, asiti ea ascorbic e ke ke ea sebelisoa ka tranelate hobane motsoako o sebetsang o ka hlaseloa habonolo ke oxidation mme o senyeha kapele. Ka hona, ho lokisoa joalo ka lyophilisate kapa tsamaiso e le phofo ho molemo.
Tabeng ea serum e nang le asiti ea ascorbic, sebopeho se lokela ho ba le pH e nang le asiti e tiileng ho etsa bonnete ba ho kenella ka ho fetisisa letlalong. Tsamaiso e lokela ho ba mochine o thibelang moea. Li-derivatives tsa vithamine C tse fokolang letlalo kapa tse mamellehang haholoanyane le tse lulang li tsitsitse esita le li-cream bases li loketse ka ho khetheha bakeng sa letlalo le nang le bothata kapa sebaka sa mahlo a masesaane.
Hoa tsebahala hore bongata bo bongata ba motsoako o sebetsang ha bo bolele hore ho na le phello e betere ea tlhokomelo. Ke khetho e hlokolosi feela le ho hlophisoa ho ikamahanyang le motsoako o sebetsang ho netefatsa hore bioavailability e ntle, ho mamella letlalo hantle, botsitso bo phahameng, le ts'ebetso e ntle ka ho fetisisa ea sehlahisoa.
