Hydroxyethylcellulose (HEC) yog cov dej-soluble polymer feem ntau siv hauv kev tsim cov gels vim nws cov thickening, stabilizing, thiab gelling zog. HEC gels tau siv ntau yam kev siv, suav nrog cov khoom tu tus kheej, tshuaj, thiab zaub mov.
Txhawm rau tsim HEC gel, cov polymer yog thawj zaug tawg hauv dej thiab tom qab ntawd sib tov kom txog thaum muaj dej txaus. Qhov no feem ntau yuav tsum tau maj mam nplawm lossis sib tov rau ob peb feeb kom ntseeg tau tias cov polymer tau tawg tag nrho thiab hydrated. Cov txiaj ntsig HEC yog tom qab ntawd rhuab mus rau qhov kub thiab txias, uas nyob ntawm qib tshwj xeeb ntawm HEC tau siv, txhawm rau qhib cov khoom gelling ntawm cov polymer.
HEC gel tuaj yeem hloov kho ntxiv los ntawm kev sib ntxiv ntawm lwm cov khoom xyaw, xws li cov khoom xyaw nquag, cov tshuaj tsw qab, lossis cov tshuaj pleev xim. Cov txheej txheem tshwj xeeb ntawm cov gel yuav nyob ntawm qhov xav tau ntawm cov khoom kawg.
Ib qho txiaj ntsig ntawm kev siv HEC hauv gel formulations yog nws lub peev xwm los muab ib tug du, creamy zoo nkauj rau cov khoom kawg. HEC gels kuj muaj kev ruaj khov thiab tuaj yeem tswj tau lawv cov kev ntxhib los mos thiab viscosity nyob rau ntau qhov kub thiab txias thiab pH.
Ntxiv nrog rau nws cov khoom ruaj khov thiab thickening, HEC kuj tseem muaj cov khoom ua kom dej thiab cov yeeb yaj kiab tsim, uas tuaj yeem ua rau nws muaj txiaj ntsig zoo hauv cov khoom tu tus kheej xws li moisturizers thiab tshuaj pleev thaiv hnub. HEC kuj tseem siv tau los ua tus neeg sawv cev ncua hauv cov qauv uas yuav tsum muaj kev faib tawm ntawm cov khoom lossis cov khoom xyaw.
HEC gels feem ntau yog siv ntau yam khoom siv tu tus kheej, nrog rau cov plaub hau gels, tshuaj ntxuav lub ntsej muag, thiab ntxuav lub cev. Lawv tuaj yeem siv tau rau hauv cov chaw muag tshuaj raws li kev xa khoom rau cov tshuaj pleev xim lossis ua cov tshuaj pleev xim rau hauv cov tshuaj ua kua.
