Ungangoziva zvishoma nezve kojic acid, asi kojic acid inewo dzimwe nhengo dzemhuri, dzakadai se kojic dipalmitate. Kojic acid dipalmitate ndiyo inonyanya kufarirwa mukugadzirwa kwekojic acid pamusika pari zvino. Tisati taziva kojic acid dipalmitate, ngatitangei tadzidza nezveyakaitangira - "kojic acid".
Kojic Acidinogadzirwa nekuvirisa uye kucheneswa kweglucose kana sucrose pasi pekushanda kwekojise. Maitiro ayo ekuchena ndeyekudzivisa kushanda kwetyrosinase, kudzivirira kushanda kweN-hydroxyindole acid (DHICA) oxidase, uye kudzivirira polymerization yedihydroxyindole (DHI). Ichinhu chimwe chete chisinganzwisisike chinogona kudzivirira ma enzymes akawanda panguva imwe chete.

Asi kojic acid ine kusagadzikana kwemaion echiedza, kupisa uye esimbi, uye haisi nyore kunyudzwa neganda, saka maderivatives ekojic acid akatanga kuvapo. Vaongorori vakagadzira maderivatives akawanda ekojic acid kuti vavandudze mashandiro ekojic acid. Maderivatives ekojic acid haasi chete ane nzira imwechete yekuchenesesa sekojic acid, asiwo ane mashandiro ari nani pane kojic acid.
Mushure mekugadziriswa kwe ester ne kojic acid, monoester ye kojic acid inogona kuumbwa, uye diester inogonawo kuumbwa. Parizvino, chinhu chinonyanya kufarirwa pamusika chekuchenesa kojic acid i kojic acid dipalmitate (KAD), inova derivative ye kojic acid yakasanganiswa ne diester. Tsvagiridzo inoratidza kuti mhedzisiro yekuchenesa ye KAD yakawedzerwa ne glucosamine derivatives ichawedzera zvakanyanya.

Kushanda zvakanaka kweKojic dipalmitate pakuchengetedza ganda
1) Kuchenesa: Kojic acid dipalmitate inoshanda kupfuura kojic acid mukudzivirira kushanda kwetyrosinase paganda, nokudaro ichidzivirira kuumbwa kwemelanin, iyo ine mhedzisiro yakanaka pakuchena kweganda uye sunscreen.
2) Kubvisa mavanga: Kojic acid dipalmitate inogona kuvandudza ruvara rweganda, uye inogona kurwisa mavanga ezera, mavanga ekutambanudza, mavanga uye ruvara rweganda.

Gwaro reDipalmitate rekugadzira zvinhu zvinoyevedza
Kojic acid dipalmitateZvakaoma kuwedzera mufomura uye zviri nyore kugadzira crystal precipitation. Kuti dambudziko iri rigadziriswe, zvinokurudzirwa kuwedzera isopropyl palmitate kana isopropyl myristate muchikamu chemafuta chine kojic dipalmitate, kupisa chikamu chemafuta kusvika 80 ℃, chengeta kwemaminitsi mashanu kusvika kojic dipalmitate yanyungudika zvachose, wobva wawedzera chikamu chemafuta muchikamu chemvura, wobva waisa emulsify kwemaminitsi angangoita gumi. Kazhinji, pH kukosha kwechigadzirwa chekupedzisira chawanikwa inenge iri 5.0-8.0.
Chiyero chinokurudzirwa chekojic dipalmitate muzvizoro i1-5%; Wedzera 3-5% muzvigadzirwa zvekuchenesa.
