Ho Senola 'Nete ka Morao Kojic Acid Dipalmitate le Katleho ea eona
Kojic acid dipalmitate, e tsejoang hape e le 2-Palmitoylmethyl-5-palmitoyl-pyrone, ke motsoako o qhibilihang ka mafura oa kojic acid. Ke motsoako o sebetsang o fumaneng botumo indastering ea litlolo ka lebaka la matla a eona a khanyang le a thibelang melanin. Sehloohong sena, re tla hlahloba katleho ea kojic acid dipalmitate le ho fana ka leseli mabapi le melemo e ka bang teng bakeng sa letlalo.
Aogubio, k'hamphani e ikhethang ka ho hlahisa le ho ajoa ha lintho tse sebetsang ka meriana, lisebelisoa tse tala, lihlahisoa tsa limela le phepo e nepahetseng, e bile moetsi ea ka sehloohong oa kojic acid dipalmitate. Aogubio e iketsetse indastering ea meriana, lijo, phepo e nepahetseng le litlolo ka ho fana ka lihlahisoa tsa boleng bo holimo bakeng sa tšebeliso ea batho. Ka botsebi le tsebo ea bona, Aogubio e atlehile ho sebelisa kojic acid dipalmitate tlhahisong ea litlolo, e etsa hore e be mohloli o tšepahalang bakeng sa motsoako ona o matla.
Kojic acid, selelekela sa kojic acid dipalmitate, ke ntho e chelating e hlahisoang ke li-fungus tse 'maloa tse kang Aspergillus oryzae, Aspergillus parasiticus, le Aspergillus flavus. E boetse e fumanoa lijong tse lomositsoeng joalo ka soy sauce, soybean paste le veine. Majapane a 'nile a sebelisa kojic acid ka lilemo tse makholo ho hlahisa veine ea Japane ea raese, e tsejoang e le "jiu koji." Japane esale e le moetsi ea ka sehloohong oa kojic acid lefatšeng ka bophara ho tloha ka bo-1970.
Ntho e ikhethang ea kojic acid dipalmitate e itšetlehile ka botsitso le katleho ea eona ha e bapisoa le kojic acid ea setso. Asiti ea Kojic e tsebahala ka ho se tsitse ha eona ho khanya, mocheso le li-ion tsa tšepe, tse ka senyang katleho ea eona. Leha ho le joalo, ka kenyelletso ea kojic acid dipalmitate, mefokolo ena ea hlōloa. Esterification ea sehlopha se sebetsang sa hydroxyl ka sebopeho sa limolek'hule tsa kojic acid dipalmitate e e sireletsa hore e se ke ea theha likamano tsa hydrogen le lisebelisoa tse ling tsa litlolo. Sena se tiisa hore ts'ebetso ea li-additives tse ling ha e amehe, e lumellang tšebelisano e ntle le lisebelisoa tse ling tse tala ka litlolo.
E 'ngoe ea melemo e ka sehloohong ea kojic acid dipalmitate ke bokhoni ba eona ba ho thibela ho thehoa ha melanin. Melanin e ikarabella bakeng sa ho fifala ha letlalo, 'me tlhahiso ea eona e feteletseng e ka lebisa ho hyperpigmentation le molumo oa letlalo o sa lekaneng. Ka ho thibela tyrosinase, e leng enzyme e amehang tlhahisong ea melanin, kojic acid dipalmitate e thusa ho khantša letlalo le ho fokotsa ponahalo ea matheba a lefifi le likoli. Sebopeho se ikhethang sa kojic acid dipalmitate se tiisa hore mosebetsi oa eona o babatsehang o bolokiloe, o fana ka liphello tse atlehang bakeng sa ho khanya ha letlalo.
Ho feta moo, kojic acid dipalmitate e fana ka thepa ea mongobo, e etsa hore e be motsoako o loketseng litlolong. Ho lumellana ha eona le lisebelisoa tse ling tse tala tsa litlolo ho e lumella ho sebetsa ka mokhoa o ts'oanang, ho fana ka hydration letlalong ntle le ho senya katleho ea li-additives tse ling. Sena se etsa hore kojic acid dipalmitate e be motsoako o fapaneng o sa khabiseng letlalo feela empa hape o le fepa le ho le fa metsi, ho etsa hore letlalo le be le bophelo bo botle le le khanyang.
Qetellong, kojic acid dipalmitate ke motsoako o matla indastering ea litlolo, e tsejoang ka ho khantša letlalo le ho thibela melanin-inhibiting. Aogubio, k'hamphani e tsebahalang e sebetsanang le tlhahiso le kabo ea lintho tse sebetsang le lisebelisoa tse tala, e atlehile ho kenyelletsa kojic acid dipalmitate lihlahisoa tsa bona tsa litlolo. Ka botsitso ba eona, ts'ebetso ea eona, le thepa ea moisturizing, kojic acid dipalmitate e fana ka tharollo e ntle bakeng sa ba batlang ho ntlafatsa ponahalo ea letlalo la bona le ho fumana lebala le ho feta.
Tlhaloso ea Lihlahisoa
Kojic acid dipalmitate e fetotsoe ho tsoa ho kojic acid, e sa feliseng feela ho se tsitse ha leseli, mocheso le ion ea tšepe, empa hape e boloka ts'ebetso ea inhibitory tyrosinase le ho thibela ho etsoa ha melanin. Kojic dipalmitate e na le thepa e tsitsitseng ea lik'hemik'hale. E ke ke ea fetoha mosehla bakeng sa oxidation, metallic ion, khanya le ho futhumatsa.
Mosebetsi
- kojic acid dipalmitate ke mofuta oa inhibitor e khethehileng bakeng sa melanin. E ka thibela ts'ebetso ea tyrosinase ka ho kopanya le ion ea koporo liseleng ka mor'a hore e kene liseleng tsa letlalo. Kojic acid le derivative ea eona e na le phello e ntle ea ho thibela tyrosinase ho feta lisebelisoa tse ling tse soeufatsang letlalo.
- kojic acid dipalmitate e ka boela ea felisa radical ea mahala, ea matlafatsa tšebetso ea lisele le ho boloka lijo li le ncha.
