Ethyl ascorbic acid
Ethyl Ascorbic Acid yog ib qho zoo heev ntawm daim tawv nqaij ntxuav hniav dawb, nws inhibits qhov kev ua ntawm Tyrosinase los ntawm kev ua ntawm Cu2 + thiab nws tiv thaiv cov synthesis ntawm melanin. ib tug zoo heev stability nyob rau hauv tag nrho cov hom ntawm cov tshuaj pleev ib ce formulations.
Ethyl Ascorbic Acid nkag mus rau hauv daim tawv nqaij qhov chaw uas nws metabolized rau ascorbic acid.Vim cov txheej txheem no nws cov kev ua tau zoo isore pronounced tshaj ib qho ntawm cov ntshiab ascorbic acid.Non irritating rau ntawm daim tawv nqaij thiab ob lub qhov muag.

Vitamin C
Niaj hnub no, ntau yam vitamin C derivatives yog siv rau hauv cov tshuaj pleev ib ce rau kev siv sab nraud.Ntshiab vitamin C, ascorbic acid los yog tseem hu ua L-ascorbic acid (ascorbic acid) muaj cov nyhuv ncaj qha.In sib piv rau lwm yam, nws tsis yog thawj zaug yuav tsum tau hloov dua siab tshiab rau hauv daim ntawv nquag.Cov kev tshawb fawb pom tau tias vitamin C txhawb collagen synthesis thiab tua cov dawb radicals.Nws tseem muaj txiaj ntsig zoo tiv thaiv pob txuv thiab hnub nyoog me ntsis los ntawm inhibiting tyrosinase.Txawm li cas los xij, ascorbic acid tsis tuaj yeem ua tiav rau hauv cov kua nplaum vim tias cov khoom xyaw nquag ua rau oxidation thiab decomposes sai heev.Yog li ntawd, kev npaj ua lyophilisate lossis kev tswj hwm raws li cov hmoov yog tsim nyog.
Nyob rau hauv cov ntaub ntawv ntawm ib tug serum muaj ascorbic acid, cov formulation yuav tsum muaj ib tug nruj pH nqi kom paub meej tias qhov zoo tshaj plaws tau nkag mus rau hauv daim tawv nqaij.Kev tswj hwm yuav tsum yog airtight dispenser.Cov vitamin C derivatives uas tsis tshua muaj tawv nqaij ua haujlwm lossis ua kom ntev dua thiab ua kom ruaj khov txawm tias nyob hauv cov nplaum nplaum tshwj xeeb yog tsim rau cov tawv nqaij rhiab lossis qhov muag nyias.
Nws paub zoo tias qhov siab ntawm cov khoom xyaw nquag tsis txhais tau tias muaj kev saib xyuas zoo dua.Tsuas yog cov kev xaiv ua tib zoo xaiv thiab cov qauv tsim kho kom haum rau cov khoom xyaw ua kom pom kev bioavailability, zoo ntawm daim tawv nqaij, kev ruaj ntseg siab, thiab cov khoom ua tau zoo tshaj plaws.
