Dab tsi yogDeoxyarbutin?
Cov qauv sib txawv ntawm arbutin thiab deoxyarbutin
Deoxyarbutin (C12h16o4) yog cov khoom siv hluavtaws ntawm lub cev muaj tshwm sim arbutin[1]. Qhov kev tshem tawm ntawm ib pawg hydroxyl (-h) txhim kho nws cov ruaj khov thiab cov xyoob ntoo kom haum rau nws cov thawj[2]{{0. hauv cov tshuaj pleev ib ce, nws ua haujlwm ua tus neeg sawv cev tawv nqaij uas tiv thaiv melanin ntau lawm los ntawm kev cuam tshuam nrog tyrosinase enzymes[3].
Kev Nyab Xeeb Profile rau Kev Siv Txuj Ci
Kev ntsuas thib peb tog ua kom pom kev ua kom muaj kev ua raws
Cov kev tshawb fawb tam sim no qhia tau tias muaj kev nyab xeeb kom muaj kev nyab xeeb rau kev tsim cov kev txwv tsis pub dhau los:
Tsawg iritation muaj peev xwm: Ib txoj kev kawm 2010 tau tshaj tawm tsawg dua qhov kev ntsuas tsis zoo ntawm 3% siab[4].
Photostability: Ua kom pom ntau ntau dua rau UV degradation tshaj alpha-arbutin[5].
Kev cai tswj hwm: Teev nyob rau hauv cosing database raws li tus neeg sawv cev tawv nqaij[6].
Qhov tseem ceeb siv kev txiav txim siab
| Chaw ua uas tsis tau haus | Lus ntuas |
|---|---|
| Ua Haujlwm Ntau Yam | 0.5% {- 3% hauv cov khoom kawg |
| PHEEJ YEEM | 4.0 - 7.0 |
| Qho so | Hauv qab 40℃thaum ua |
