Wataƙila ka san kaɗan game da kojic acid, amma kojic acid ma yana da wasu 'yan uwa, kamar kojic dipalmitate. Kojic acid dipalmitate shine mafi shaharar maganin farin acid na kojic a kasuwa a yanzu. Kafin mu san kojic acid dipalmitate, bari mu fara koyo game da wanda ya gabace shi - "kojic acid".
Kojic AcidAna samar da shi ta hanyar fermentation da tsarkake glucose ko sucrose a ƙarƙashin aikin kojise. Tsarinsa na bleaching shine hana aikin tyrosinase, hana aikin N-hydroxyindole acid (DHICA) oxidase, da kuma toshe polymerization na dihydroxyindole (DHI). Wani abu ne mai sauƙin yin bleaching wanda zai iya hana enzymes da yawa a lokaci guda.

Amma kojic acid yana da rashin daidaiton haske, zafi da kuma rashin daidaiton ion na ƙarfe, kuma ba shi da sauƙin sha daga fata, don haka an samar da abubuwan da aka samo daga kojic acid. Masu bincike sun ƙirƙiro abubuwa da yawa na kojic acid don inganta aikin kojic acid. Abubuwan da aka samo daga kojic acid ba wai kawai suna da tsarin farin ciki iri ɗaya da kojic acid ba, har ma suna da aiki mafi kyau fiye da kojic acid.
Bayan an yi amfani da sinadarin kojic acid, ana iya samar da monoester na kojic acid, kuma ana iya samar da diester. A halin yanzu, mafi shaharar sinadarin kojic acid mai farin gashi a kasuwa shine kojic acid dipalmitate (KAD), wanda aka samo daga kojic acid mai narkewa. Bincike ya nuna cewa tasirin farin gashi na KAD wanda aka haɗa shi da glucosamine zai ƙaru sosai.

Ingancin kula da fata na kojic dipalmitate
1) Farar fata: Kojic acid dipalmitate ya fi kojic acid tasiri wajen hana aikin tyrosinase a fata, don haka yana hana samuwar melanin, wanda ke da tasiri mai kyau akan farin fata da kuma hasken rana.
2) Cire freckle: Kojic acid dipalmitate na iya inganta launin fata, kuma yana iya yaƙi da tabo na shekaru, alamun miƙewa, freckles da kuma launin baki gaba ɗaya.

Jagorar haɗa kayan kwalliya na Dipalmitate
Kojic acid dipalmitateYana da wuya a ƙara wa dabarar kuma yana da sauƙin samar da ruwan sama mai yawa. Domin magance wannan matsalar, ana ba da shawarar a ƙara isopropyl palmitate ko isopropyl myristate a cikin man da ke ɗauke da kojic dipalmitate, a dumama man zuwa 80 ℃, a riƙe na minti 5 har sai kojic dipalmitate ya narke gaba ɗaya, sannan a ƙara man zuwa ruwan, sannan a yi emulsify na kimanin minti 10.
