Khoom Taw Qhia
Kojic acidyog ib qho tsis muaj zog acid compound tsim los ntawm fermentation. Nws yog qhov hnyav molecular, tuaj yeem nqus ncaj qha los ntawm daim tawv nqaij, thiab muaj kev siv siab. Nws tuaj yeem tiv thaiv kev tsim ntawm tyrosinase, inhibit tiam ntawm melanin, thiab thaiv kev tsim ntawm melanin melanin.

Mechanism ntawm Action
Melanin yog synthesized los ntawm melanocytes nyob rau hauv qis txheej ntawm epidermis. Melanocytes raug cais nyob rau hauv qeb ntawm cov hlwb tshwj xeeb dendritic uas nyob ntawm cov epidermal keratinocytes thiab lawv ua lub luag haujlwm tseem ceeb ntawm melanin tsim nyob rau hauv ib qho organelle hu ua melanosomes, thiab yog li kis mus rau ib puag ncig keratinocytes. Txhua melanocyte ua rau kev sib cuag nrog melanosomes nyob rau hauv ntau theem ntawm dendritic hlwb thiab faib nyob rau hauv ntau keratinocytes. Melanins yog cov polymers complex uas tau muab los ntawm tyrosine thiab lwm yam intermediates. Tyrosinase muaj tooj liab ions nyob rau hauv lub active site. Thaum raug UV rays, tooj liab ion txib kom tyrosinase ua kom nquag plias. Kojic Acid ntes cov tooj liab ion, tiv thaiv kom tsis txhob ua rau tyrosinase. Los ntawm inhibiting cov dej num ntawm tyrosinase, Kojic Acid tuaj yeem tiv thaiv kev tsim melanin.
Kev nyab xeeb ntawm kojic acid
Yog hais tias qhov concentration yog tswj nyob rau hauv 1%, nws muaj me ntsis irritation rau lub qhov muag thiab tawv nqaij.
Txawm hais tias tej zaum yuav muaj tsawg heev me ntsis ntawm daim tawv nqaij khaus, me ntsis ntawm daim tawv nqaij ua xua thiab lub teeb rhiab heev, tsis muaj teeb meem nrog kev nyab xeeb.
Tswv yim:
1. Kojic acid tsis ruaj khov rau lub teeb, cua sov thiab hlau ions. Tsis txhob ntxiv nws ntawm qhov kub thiab txias thaum lub sij hawm formulation. Tswj cov ntsiab lus ntawm hlau thiab lwm yam hlau ions nyob rau hauv lub system.
2. Nws yog qhov zoo dua los ntxiv cov khoom tsim nyog xws li EDTA thiab antioxidants xws li sodium sulfite hauv lub cev.
3. Pom zoo npaum li cas: 0.5 ~ 1.0%.
