● Dab tsi yog Kojic Acid Dipalmitate?
Taw qhia rau cov khoom siv raw: Kev tsim kho tshiab los ntawm kojic acid rau cov roj-soluble derivatives
Kojic acid dipalmitate (CAS No.: 79725-98-7) yog ib qho esterified derivative ntawm kojic acid, uas yog npaj los ntawm kev sib txuas kojic acid nrog palmitic acid. Nws cov mis molecular yog C₃₈H₆₆O₆ thiab nws qhov hnyav molecular yog 618.93. Kojic acid yog Ameslikas muab los ntawm cov khoom fermentation ntawm fungi xws li Aspergillus oryzae thiab yog dav siv nyob rau hauv cov zaub mov preservation thiab whitening, tab sis nws cov dej solubility thiab instability rau lub teeb, tshav kub thiab hlau ions txwv nws daim ntawv thov. Kojic acid dipalmitate tau hloov kho los ntawm esterification, uas tsis tsuas yog khaws cov kev ua kom zoo nkauj ntawm kojic acid, tab sis kuj tseem txhim kho nws txoj kev ruaj ntseg thiab muaj roj solubility, ua rau nws muaj hnub qub hauv kev lag luam tshuaj pleev ib ce.
Nws cov txheej txheem npaj muaj xws li tshuaj synthesis thiab bioenzymatic hydrolysis technology. Niaj hnub nimno technology optimizes cov tshuaj tiv thaiv tej yam kev mob (xws li high-temperature esterification los yog enzyme catalysis) kom paub meej tias cov khoom purity yog ≥98% thiab ua tau raws li cov qauv zoo nkauj-qib.
Kojic acid dipalmitateyog ib tug dawb mus rau lub teeb daj crystalline hmoov nrog ib tug melting point ntawm 92-96 ° C thiab ib tug ceev ntawm 0.99 g / cm³. Nws yog soluble hauv cov roj ntxhia, esters thiab kub ethanol, tab sis insoluble hauv dej. Cov pab pawg hydroxyl hauv nws cov qauv molecular yog esterified, uas tsis txhob hydrogen bonding nrog lwm cov khoom xyaw hauv cov tshuaj pleev ib ce (xws li cov tshuaj pleev thaiv hnub thiab tshuaj pleev thaiv hnub) thiab txhim kho kev sib xyaw ua haujlwm.
Cov txiaj ntsig tseem ceeb ntawm kojic acid dipalmitate:
Photothermal stability:Piv nrog kojic acid, nws lub teeb thiab kub tsis kam yog ua kom zoo dua qub, tsis txhob muaj xim daj los ntawm kev sib cuag nrog cov hlau ions.
Fat-soluble yam ntxwv:Nws yog yooj yim soluble nyob rau hauv roj-theem qauv, muaj peev xwm ntau npaum nkag mus rau lub stratum corneum ntawm daim tawv nqaij, thiab txhim khu kev nqus efficiency.
● Dab tsi yog Cov txiaj ntsig ntawmKojic Acid Dipalmitate?
Kojic acid dipalmitate ua tiav cov teebmeem kev tu tawv nqaij los ntawm ntau lub tshuab:
1. Cov tshuaj ntxuav hniav dawb zoo heev:
Inhibit tyrosinase kev ua: Los ntawm chelating tooj liab ions (Cu² ⁺), nws thaiv txoj hauv kev tsim cov melanin, thiab muaj cov nyhuv whitening dua kojic acid. Cov ntaub ntawv kho mob qhia tau tias nws cov tshuaj melanin inhibition tuaj yeem ncav cuag ntau dua 80%.
Lighten qhov chaw:Kojic Acid Dipalmitatemuaj kev txhim kho tseem ceeb ntawm pigmentation xws li hnub nyoog me ntsis, ncab cov cim, freckles, thiab lwm yam.
2. Antioxidant thiab anti-aging:
Nws muaj qhov zoo tshaj plaws dawb radical scavenging peev xwm, txo ultraviolet-induced oxidative kev puas tsuaj, ncua collagen degradation, thiab pab tiv thaiv wrinkle.
3. Kev ua siab mos thiab kev nyab xeeb:
Nws tau teev tseg raws li cov khoom siv tshuaj pleev ib ce zoo los ntawm US CTFA, EU thiab Tuam Tshoj Food and Drug Administration. Nws yog non-irritating thiab haum rau cov tawv nqaij rhiab heev.
● Dab tsi yog Cov Ntawv Thov Ntawm Kojic Acid Dipalmitate ?
1. Kev lag luam tshuaj pleev ib ce:
Cov khoom ua kom tawv nqaij: Ntxiv rau lub ntsej muag cream, cov ntsiab lus (pom zoo 1%-3%), qhov ncauj qhov ntswg, thiab lwm yam, xws li kev sib xyaw nrog glucosamine derivatives los ua ob npaug ntawm cov nyhuv whitening.
Tshuaj pleev thaiv hnub thiab kho: Ua haujlwm nrog cov tshuaj pleev thaiv hnub lub cev xws li zinc oxide los txhim kho UV tiv thaiv thiab kho lub teeb puas.
Cov khoom siv los tiv thaiv kev laus: Siv rau hauv cov tshuaj tiv thaiv wrinkle thiab tshuaj pleev qhov muag kom txo cov kab zoo.
2. Tshuaj thiab kev saib xyuas tshwj xeeb:
Tshawb nrhiav kev siv nws hauv kev kho cov kab mob pigmentary (xws li chloasma) thiab kho cov xim tom qab hlawv.
3. Emerging fields:
Daim ntawv thov ntawm nanotechnology: Txhim kho qhov ruaj khov ntawm cov khoom xyaw los ntawm kev siv tshuab encapsulation, ua tiav kev tso tawm mus ntev, thiab txhim kho cov khoom siv tau zoo.
