Ua ʻike iki paha ʻoe e pili ana i ka waikawa kojic, akā he mau lālā ʻohana ʻē aʻe ko ka waikawa kojic, e like me ka kojic dipalmitate. ʻO ka waikawa kojic dipalmitate ka mea hoʻokeʻokeʻo waikawa kojic kaulana loa ma ka mākeke i kēia manawa. Ma mua o ko mākou ʻike ʻana i ka waikawa kojic dipalmitate, e aʻo mua kākou e pili ana i kona mua - "kojic acid".
ʻAkika KojicUa hana ʻia ma o ka fermentation a me ka hoʻomaʻemaʻe ʻana o ka glucose a i ʻole sucrose ma lalo o ka hana a kojise. ʻO kāna ʻano hoʻokeʻokeʻo, ʻo ia ke kāohi i ka hana o tyrosinase, kāohi i ka hana o ka N-hydroxyindole acid (DHICA) oxidase, a ālai i ka polymerization o dihydroxyindole (DHI). He mea hoʻokeʻokeʻo hoʻokahi kakaikahi e hiki ke kāohi i nā enzyme he nui i ka manawa like.

Akā, he māmā, wela a me ka paʻa ʻole o ka ion metala ko ka waikawa kojic, a ʻaʻole maʻalahi ke komo ʻia e ka ʻili, no laila ua puka mai nā mea hoʻohui waikawa kojic. Ua hoʻomohala nā kānaka noiʻi i nā mea hoʻohui waikawa kojic he nui e hoʻomaikaʻi i ka hana o ka waikawa kojic. ʻAʻole wale ka ʻano hoʻokeʻokeʻo like o nā mea hoʻohui waikawa kojic me ka waikawa kojic, akā ʻoi aku ka maikaʻi o ka hana ma mua o ka waikawa kojic.
Ma hope o ka esterification me ka waikawa kojic, hiki ke hoʻokumu ʻia ka monoester o ka waikawa kojic, a hiki nō hoʻi ke hoʻokumu ʻia ka diester. I kēia manawa, ʻo ka mea hoʻokeʻokeʻo waikawa kojic kaulana loa ma ka mākeke ʻo ia ka kojic acid dipalmitate (KAD), he derivative diesterified o ka waikawa kojic. Hōʻike ka noiʻi e hoʻonui nui ʻia ka hopena hoʻokeʻokeʻo o KAD i hui pū ʻia me nā derivatives glucosamine.

Ka pono o ka mālama ʻili o kojic dipalmitate
1) Keʻokeʻo: ʻOi aku ka maikaʻi o ka dipalmitate Kojic acid ma mua o ka kojic acid i ka pale ʻana i ka hana o tyrosinase i loko o ka ʻili, no laila e pale ana i ka hoʻokumu ʻia ʻana o ka melanin, kahi hopena maikaʻi i ka hoʻokeʻokeʻo ʻana i ka ʻili a me ka sunscreen.
2) Ka wehe ʻana i nā freckle: Hiki i ka Kojic acid dipalmitate ke hoʻomaikaʻi i ka pigmentation ʻili, a hiki ke hakakā i nā wahi makahiki, nā māka kīkoʻo, nā freckles a me ka pigmentation maʻamau.

Alakaʻi hoʻohuihui hoʻonani Dipalmitate
ʻO ka dipalmitate waikawa KojicHe paʻakikī ke hoʻohui i ke ʻano hana a maʻalahi hoʻi e hana i ka ua kristal. I mea e hoʻoponopono ai i kēia pilikia, ua ʻōlelo ʻia e hoʻohui i ka isopropyl palmitate a i ʻole isopropyl myristate i ka pae aila e loaʻa ana ka kojic dipalmitate, e hoʻomehana i ka pae aila i 80 ℃, e paʻa no 5 mau minuke a hiki i ka wā e hoʻoheheʻe loa ʻia ai ka kojic dipalmitate, a laila e hoʻohui i ka pae aila i ka pae wai, a emulsify no kahi o 10 mau minuke. Ma keʻano laulā, ʻo ka waiwai pH o ka huahana hope loa i loaʻa ma kahi o 5.0-8.0.
ʻO ka nui i manaʻo ʻia o kojic dipalmitate i nā mea hoʻonani he 1-5%; E hoʻohui i ka 3-5% i nā huahana keʻokeʻo.
