Kojic acidayinxulumananga necandelo "leasidi". Yimveliso yendalo ye-Aspergillus fermentation (i-asidi ye-Kojic lilungu elifunyenwe kwi-koji etyiwayo yomngundo kwaye idla ngokufumaneka kwisosi yesoya, kwiziselo ezinxilisayo, kunye nezinye iimveliso ezivundisiweyo. I-asidi ye-Kojic inokubonwa kwiimveliso ezininzi ezivundisiweyo ze-Aspergillus fermentation. Kojic acid ngoku ingenziwa ngokwenziwa).
I-asidi ye-Kojic yikristale yeprismatic engenambala enokuthintela umsebenzi we-tyrosinase ngexesha lokuveliswa kwe-melanin. Ayinayo imiphumo eyityhefu kwezinye ii-enzymes kunye neeseli. Umxholo ongaphantsi kwe-2% unokunciphisa ngokufanelekileyo ukufakwa kwe-melanin kwaye ube mhlophe kakhulu ngaphandle kokuthintela ezinye ii-enzymes.
Isetyenziswe ngokubanzi kwishishini lemichiza yemihla ngemihla njengeukwenza mhlophe, ukukhuselwa kwelanga, izinto zokuthambisa, izinyibilikisi, intlama yamazinyo, njl.
Umsebenzi obaluleke kakhulu - umhlophe
I-asidi ye-Kojic ingena esikhumbeni kwaye ikhuphisane ne-tyrosinase ye-ion yobhedu, ithintela umsebenzi we-amino acid enzymes kunye nokubonelela nge-tyrosinase engasebenziyo, ngaloo ndlela ivalela ukuveliswa kwe-melanin. Ifezekisa umphumo wokuba mhlophe kunye namabala okukhanya, kwaye ibe nefuthe elibalulekileyo ekuvimbeleni i-melanin yobuso kunye namabala.
Ifomula equlethe i-1% ye-quercetin ibonakaliswe ukuba inciphisa ngokufanelekileyo amabala eminyaka yobudala, i-pigmentation egqithisileyo emva kokuvuvukala, i-freckles, kunye ne-melasma.
Ukudibanisa i-quercetin kunye ne-alpha hydroxy acids (iziqhamo ze-acids) nazo zinokulawula amabala ebudala kwaye zikhanyise i-freckles.
I-asidi ye-Kojic ayinayo kuphela imiphumo emhlophe, kodwa iphinde ibe ne-free radical scavenging kunye ne-antioxidant properties. Inokunceda ukuqinisa ulusu, ukukhuthaza ukuhlanganiswa kweeprotheyini, kunye nokuqinisa ulusu. Ayinayo kuphela iipropathi ezithile ze-antibacterial, kodwa ikwanazo ezithileukufumaisakhono, kwaye sinokusetyenziswa njengesigcinakaliso ekutyeni nakwizinto zokuthambisa.
Iingcebiso
▲ Nikela ingqalelo kumhlophe ophakathi kwaye uzame ukungasebenzisi izithambiso ze-citric acid ixesha elide, njengoko ubumhlophe obugqithisileyo bunokukhokelela kwi-melanin eyaneleyo, umhlaza wolusu, amabala amhlophe, njl.
Izithambiso ezine-quercetin zisetyenziswa kakuhle ebusuku, ngakumbi ukuthintela ukusetyenziswa kwe-salicylic acid, i-asidi yeziqhamo, kunye nokuxinana okuphezulu kwe-asidi.VC.
▲ Gwema ukusebenzisa izimonyo eziqukethe ngaphezu kwe-2% yoxinaniso lwe-quercetin.
