Daim ntawv thov
Hais txog kev siv, qhov sib xyaw no feem ntau yog ua haujlwm hauv kev tsim cov dav -spectrum UV- absorbing agents rau cosmetic thiab khoom tu tus kheej. Nws cov yam ntxwv ntawm cov qauv tso cai rau nws nqus UVA thiab UVB hluav taws xob, ua rau nws tsim nyog siv rau hauv cov tshuaj pleev thaiv hnub, tshuaj pleev, thiab lwm yam tawv nqaij - cov tshuaj tiv thaiv. Tsis tas li ntawd, nws tuaj yeem ua haujlwm nruab nrab hauv kev txhim kho cov duab- cov khoom siv ruaj khov thiab qib siab UV- lim molecules rau kev txhim kho kev ua tau zoo hauv cov khoom siv hnub ci. Tshaj li cov tshuaj pleev ib ce, nws yuav siv tau rau hauv kev tshawb fawb thiab kev lag luam synthesis ntawm cov tshuaj tsw qab esters nrog photoprotective zog los yog hauv cov ntaub ntawv siv science uas yuav tsum tau muaj kev tiv thaiv UV.
Cov txiaj ntsig
Cov txiaj ntsig ntawm 2-(4-(Diethylamino)-2-hydroxybenzoyl) benzoic acid hexyl ester tshwm sim los ntawm nws qhov muaj zog UV nqus, tshuaj lom neeg ruaj khov, thiab kev sib raug zoo nrog cov qauv roj. Nws cov ester functionality thiab lipophilic hexyl saw txhim kho solubility nyob rau hauv cov organic theem, ua kom yooj yim formulation nyob rau hauv cream thiab tshuaj pleev ib ce. Cov pab pawg hydroxybenzoyl thiab diethylamino muab kev tiv thaiv kev tiv thaiv zoo thaum txo qis photodegradation, txhim kho cov kav ntev thiab kev ua tau zoo ntawm cov khoom siv tshuaj pleev thaiv hnub. Tsis tas li ntawd, nws qhov kev ruaj ntseg nyob rau hauv ntau yam ntawm ib puag ncig ua kom muaj kev ua tau zoo ib yam, ua rau nws muaj kev ntseeg siab nruab nrab lossis cov khoom muaj txiaj ntsig hauv UV-tiv thaiv daim ntawv thov.
Xaus
Hauv kev xaus, 2-(4-(Diethylamino)-2-hydroxybenzoyl) benzoic acid hexyl ester yog ib qho tseem ceeb rau UV-filter synthesis thiab kev txhim kho cov khoom tu lub hnub. Nws daim ntawv thov nyob rau hauv cov tshuaj pleev ib ce formulations thiab photostable intermediate synthesis, ua ke nrog cov txiaj ntsig xws li muaj zog UV nqus, tshuaj lom neeg ruaj khov, thiab lipophilicity, ua rau nws muaj txiaj ntsig zoo hauv cov tshuaj pleev thaiv hnub niaj hnub thiab kev tshawb fawb photoprotection. Qhov sib xyaw ua ke txhawb nqa kev tiv thaiv ntawm daim tawv nqaij thiab cov khoom ruaj khov hauv daim ntawv thov kev saib xyuas tus kheej.
