Cov dej txias instant hydroxypropyl methylcellulose (HPMC) yog ib qho uas tsis yog-ionic cellulose ether dav siv nyob rau hauv ntau yam lag luam nrog rau kev lag luam tshuaj niaj hnub. HPMC yog cov khoom siv nrov hauv ntau yam kev saib xyuas tus kheej thiab cov khoom siv tu tsev vim nws cov dej tuav tau zoo thiab muaj peev xwm ua kom tuab. Hauv tsab xov xwm no, peb yuav tham txog cov txiaj ntsig ntawm kev siv dej txias tam sim HPMC hauv kev lag luam tshuaj txhua hnub.
Txhim kho kev ruaj ntseg
Ib qho txiaj ntsig tseem ceeb ntawm kev siv dej txias tam sim HPMC hauv kev saib xyuas tus kheej thiab cov khoom siv tu tsev yog txhim kho kev ruaj ntseg. HPMC yog cov khoom siv hydrophilic uas tuaj yeem nqus tau thiab khaws cov dej ntau. Yog li, nws pab tswj cov khoom ruaj khov los ntawm kev tiv thaiv cov khoom kom qhuav los yog poob kev ntxhib los mos ntawm lub sijhawm.
Tsis tas li ntawd, HPMC muaj cov cuab yeej ua yeeb yaj kiab zoo heev, uas pab tsim cov txheej txheem sib xws thiab zoo ib yam ntawm cov khoom. Qhov no tiv thaiv cov khoom los ntawm lwm yam xws li av noo, tshuaj lom neeg thiab kub hloov, yog li txhim kho cov khoom ruaj khov.
Txhim kho viscosity
Lwm qhov txiaj ntsig ntawm kev siv dej txias tam sim HPMC hauv kev saib xyuas tus kheej thiab cov khoom siv tu tsev yog nce viscosity. HPMC muaj cov khoom thickening uas tuaj yeem txhim kho kev ntxhib los mos thiab viscosity ntawm cov khoom. Qhov no yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig rau cov khoom lag luam uas xav tau kev sib xws, xws li tshuaj zawv plaub hau, ntxuav lub cev thiab xab npum ua kua.
Tsis tas li ntawd, HPMC muaj nyob rau hauv ntau qib viscosity, txhais tau tias cov tuam ntxhab tuaj yeem xaiv cov qib uas zoo tshaj plaws rau lawv cov khoom tshwj xeeb. Qhov no tso cai rau kev hloov pauv ntau dua hauv cov khoom tsim, uas yog qhov tseem ceeb hauv kev lag luam tshuaj pleev ib ce uas muaj kev sib tw.
Txhim kho kev tuav dej
Cov dej txias tam sim HPMC tshwj xeeb tshaj yog tsim rau cov khoom uas xav tau kev tuav dej siab. HPMC tuaj yeem nqus tau thiab khaws cov dej ntau, pab kom cov tawv nqaij thiab plaub hau moisturize. Qhov no tseem ceeb tshwj xeeb tshaj yog rau cov khoom siv tu tus kheej xws li moisturizers, lotions thiab conditioners.
Tsis tas li ntawd, HPMC tseem tuaj yeem pab tiv thaiv cov evaporation ntawm cov dej hauv cov khoom. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov khoom uas raug cov av noo siab, xws li ntxuav lub cev thiab xab npum ua kua. Los ntawm kev tiv thaiv ya raws los ntawm evaporating, HPMC pab tswj kev ntxhib los mos thiab sib xws ntawm cov khoom, yog li txhim kho nws tag nrho cov zoo.
Txhim kho emulsifying zog
Thaum kawg, dej txias tam sim HPMC muaj cov khoom zoo emulsifying, uas txhais tau tias nws pab cov khoom xyaw khi thiab ruaj khov hauv cov khoom. Qhov no yog tshwj xeeb tshaj yog pab tau rau cov khoom uas muaj roj thiab dej-raws li cov khoom xyaw, xws li tshuaj pleev ib ce thiab cream.
HPMC pab tsim cov emulsion ruaj khov los ntawm kev tsim ib qho kev thaiv ntawm cov roj thiab dej theem. Qhov kev thaiv no tiv thaiv cov khoom xyaw los ntawm kev sib cais thiab pab tswj cov khoom sib xws. Qhov no txhim kho qhov zoo ntawm cov khoom los ntawm kev ua kom nws muaj kev ntxhib los mos thiab yooj yim siv.
nyob rau hauv xaus
Hauv kev xaus, dej txias instant hydroxypropyl methylcellulose (HPMC) yog ib qho khoom muaj ntau yam thiab muaj txiaj ntsig zoo hauv kev lag luam tshuaj txhua hnub. Nws cov dej tuav, thickening, stabilizing, thiab emulsifying zog ua rau nws muaj txiaj ntsig ntxiv rau ntau yam kev saib xyuas tus kheej thiab cov khoom siv tu tsev. Cov txiaj ntsig ntawm kev siv HPMC hauv cov khoom no suav nrog txhim kho kev ruaj ntseg, viscosity, dej tuav thiab emulsification zog. Nws txoj kev siv dav hauv kev lag luam hais txog qhov ua tau zoo ntawm HPMC thiab nws qhov kev cuam tshuam zoo tag nrho rau qhov zoo ntawm cov khoom siv tshuaj txhua hnub.
