Urashobora kuba uzi bike kuri acide kojic, ariko acide kojic ifite nabandi bagize umuryango, nka kojic dipalmitate. Kojic aside dipalmitate nikintu kizwi cyane cya kojic acide yera kumasoko kurubu. Mbere yuko tumenya aside ya kojic dipalmitate, reka tubanze tumenye ibyayibanjirije - “acide kojic”.
Acide Kojicikorwa na fermentation no kweza glucose cyangwa sucrose munsi ya kojise. Uburyo bwayo bwera ni ukubuza ibikorwa bya tyrosinase, kubuza ibikorwa bya aside N-hydroxyindole (DHICA) oxydease, no guhagarika polymerisation ya dihydroxyindole (DHI). Nibintu bidasanzwe byera bishobora guhagarika imisemburo myinshi icyarimwe.

Ariko aside ya kojic ifite urumuri, ubushyuhe nicyuma ion idahungabana, kandi ntabwo byoroshye kwinjizwa nuruhu, bityo ibikomoka kuri acide kojic byaje kubaho. Abashakashatsi bakoze aside nyinshi ya kojic kugirango bongere imikorere ya acide kojic. Ibikomoka kuri acide ya Kojic ntabwo bifite gusa uburyo bwo kwera nka acide kojic, ahubwo bifite imikorere myiza kuruta acide kojic.
Nyuma ya esterification hamwe na acide ya kojic, hashobora kubaho monoester ya acide kojic, kandi na dieter irashobora. Kugeza ubu, acide ya kojic izwi cyane ku isoko ni kojic aside dipalmitate (KAD), ikaba ikomoka kuri mazutu ikomoka kuri acide kojic. Ubushakashatsi bwerekana ko ingaruka zo kwera za KAD ziyongereye hamwe n'ibikomoka kuri glucosamine biziyongera cyane.

Kuvura uruhu efficacy ya kojic dipalmitate

Kugabanya uburyo bwo kwisiga bwo kwisiga
Kojic aside dipalmitateni bigoye kongeramo formula kandi byoroshye gukora imvura igwa. Kugirango iki kibazo gikemuke, birasabwa kongeramo isopropyl palmitate cyangwa isopropyl myristate mugice cyamavuta kirimo kojic dipalmitate, shyushya icyiciro cya peteroli kugeza kuri 80 ℃, fata iminota 5 kugeza kojal dipalmitate ishonga burundu, hanyuma wongereho icyiciro cyamavuta kuri icyiciro cyamazi, kandi yigana muminota 10. Mubisanzwe, pH agaciro k'ibicuruzwa byarangiye byabonetse ni 5.0-8.0.
Igipimo gisabwa cya kojic dipalmitate mumavuta yo kwisiga ni 1-5%; Ongeramo 3-5% mubicuruzwa byera.
