Kojic acidsichigwirizana ndi gawo la "acid". Ndi mankhwala achilengedwe a Aspergillus fermentation (Kojic acid ndi chinthu chotengedwa kuchokera ku bowa wa koji ndipo nthawi zambiri amapezeka mu soya msuzi, zakumwa zoledzeretsa, ndi zinthu zina zofufumitsa. Kojic acid amatha kupezeka muzinthu zambiri zofufumitsa za Aspergillus fermentation. Kojic acid. tsopano akhoza kupangidwa mwachisawawa).
Kojic acid ndi kristalo wopanda mtundu wa prismatic yemwe amatha kuletsa ntchito ya tyrosinase panthawi yopanga melanin. Lilibe poizoni zotsatira ena michere ndi maselo. Zomwe zili zosakwana 2% zimatha kuchepetsa kuyika kwa melanin ndikuyera kwambiri popanda kuletsa ma enzyme ena.
Zakhala zikugwiritsidwa ntchito kwambiri pamakampani opanga mankhwala tsiku ndi tsiku mongakuyera, kuteteza dzuwa, zodzoladzola, zosungunulira, mankhwala otsukira mano, etc.
Ntchito yofunika kwambiri - kuyeretsa
Kojic asidi amalowa pakhungu ndikupikisana ndi tyrosinase kwa ayoni amkuwa, kulepheretsa ntchito ya michere ya amino acid yovuta komanso kupangitsa kuti tyrosinase isagwire ntchito, potero kutsekereza kupanga melanin. Iwo amakwaniritsa zotsatira za whitening ndi mphezi mawanga, ndipo zimakhudza kwambiri inhibiting nkhope melanin ndi mawanga.
Fomu yomwe ili ndi 1% quercetin yatsimikiziridwa kuti imachepetsa bwino mawanga azaka, mtundu wochuluka wa pigment pambuyo pa kutupa, mabala, ndi melasma.
Kuphatikiza quercetin ndi alpha hydroxy acids (zipatso zidulo) kungathenso kuwongolera mawanga azaka ndikuwunikira ma freckles.
Kojic acid sikuti imakhala ndi zotsatira zoyera, komanso imakhala ndi ma free radical scavenging ndi antioxidant katundu. Zingathandize kumangitsa khungu, kulimbikitsa kuphatikizika kwa mapuloteni, ndi kumangitsa khungu. Sikuti ali ndi antibacterial properties, komanso ali ndi zinawonyowakuthekera, ndipo amatha kugwiritsidwa ntchito ngati chosungira muzakudya ndi zodzoladzola.
Malangizo
▲ Samalani kuyera kwapakatikati ndipo yesetsani kusagwiritsa ntchito zodzoladzola za citric acid kwa nthawi yayitali, chifukwa kuyera kwambiri kungayambitse kusakwanira kwa melanin, khansa yapakhungu, mawanga oyera, ndi zina zambiri.
Zodzoladzola zomwe zimakhala ndi quercetin zimagwiritsidwa ntchito bwino usiku, makamaka kupewa kugwiritsa ntchito salicylic acid, zipatso za acidic, komanso kuchuluka kwa mafuta m'thupi.VC.
▲ Pewani kugwiritsa ntchito zodzoladzola zomwe zili ndi quercetin yopitilira 2%.
