Hydroxypropyl methylcellulose (HPMC) thiab polyethylene glycol (PEG) yog ob hom tshuaj sib xyaw ua ke uas siv tau ntau yam hauv ntau yam lag luam.
Hydroxypropyl Methylcellulose (HPMC):
Cov Tshuaj: HPMC siv dav hauv cov tshuaj ua cov khoom ua kom tuab, cov khoom sib txuas, cov yeeb yaj kiab qub, thiab cov neeg sawv cev tso tawm tas mus li hauv cov tshuaj pleev xim thiab cov matrices tswj kev tso tawm.
Kev Xa Tshuaj Los Ntawm Qhov Ncauj: Nws ua haujlwm ua tus hloov pauv viscosity hauv cov qauv tshuaj kua xws li syrups, suspensions, thiab emulsions, txhim kho lawv qhov ruaj khov thiab saj zoo.
Cov Qauv Ophthalmic: Hauv cov tshuaj qhov muag thiab cov tshuaj ophthalmic, HPMC ua haujlwm ua cov roj nplua nyeem thiab cov neeg sawv cev txhim kho viscosity, ua kom lub sijhawm sib cuag ntawm cov tshuaj nrog qhov chaw ocular ntev dua.
Kev Npaj Siv Rau Sab Nraud: HPMC siv rau hauv cov tshuaj pleev, cov gels, thiab cov tshuaj pleev ua tus neeg sawv cev ua kom tuab, muab qhov sib xws xav tau thiab txhim kho kev sib kis ntawm cov qauv.
Cov Khoom Siv Rau Qhov Ncauj: Nws siv rau hauv cov khoom siv hydrogel rau qhov ncauj vim nws cov khoom khaws cia dej noo, pab kho qhov ncauj thiab txhawb kom muaj qhov ncauj noo.
Kev Lag Luam Tsim Kho: HPMC raug ntxiv rau cov cement-based mortars, plasters, thiab vuas nplaum kom txhim kho kev ua haujlwm, kev khaws dej, thiab cov khoom lo.
Kev Lag Luam Khoom Noj: Hauv cov khoom noj, HPMC ua haujlwm ua cov khoom ua kom tuab, ruaj khov, thiab emulsifier, txhim kho cov qauv, lub sijhawm khaws cia, thiab qhov ncauj zoo. Nws feem ntau pom muaj nyob rau hauv cov khoom ci, cov khoom siv mis nyuj hloov pauv, cov kua ntses, thiab cov kua ntses.
Cov Khoom Siv Saib Xyuas Tus Kheej: HPMC tau muab tso rau hauv cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej xws li tshuaj pleev, tshuaj pleev, thiab cov khoom saib xyuas plaub hau ua tus neeg sawv cev tuab thiab ncua, txhim kho cov khoom sib xws thiab ruaj khov.
Xim thiab Txheej: HPMC siv rau hauv cov xim thiab txheej txheej dej los tswj cov viscosity, tiv thaiv kev sagging, thiab txhim kho kev nplaum rau cov substrates.
Polyethylene Glycol (PEG):
Cov Tshuaj: PEG siv dav hauv cov tshuaj ua cov tshuaj yaj, tshwj xeeb tshaj yog rau cov tshuaj yaj tsis zoo, thiab ua lub hauv paus rau ntau yam kev xa tshuaj xws li liposomes thiab microspheres.
Cov Tshuaj Laxatives: Cov tshuaj laxatives uas muaj PEG feem ntau yog siv rau kev kho mob cem quav vim lawv cov osmotic action, rub dej mus rau hauv txoj hnyuv thiab ua kom cov quav mos.
Tshuaj pleev ib ce: PEG siv rau hauv cov tshuaj pleev ib ce xws li tshuaj pleev, tshuaj pleev, thiab tshuaj zawv plaub hau ua cov emulsifier, humectant, thiab cov kuab tshuaj, txhim kho cov khoom ruaj khov thiab cov qauv.
Cov Tshuaj Pleev Tus Kheej: Cov tshuaj pleev raws li PEG yog siv rau hauv cov khoom siv saib xyuas tus kheej thiab cov tshuaj pleev kev sib deev vim lawv cov qauv du, tsis nplaum thiab yaj tau hauv dej.
Polymer Chemistry: PEG yog siv ua tus ua ntej hauv kev tsim ntau yam polymers thiab copolymers, pab txhawb rau lawv cov qauv thiab cov khoom.
Cov Tshuaj Tiv Thaiv: PEG ua haujlwm ua cov tshuaj tiv thaiv lossis cov kuab tshuaj hauv cov organic synthesis thiab cov tshuaj tiv thaiv, tshwj xeeb tshaj yog hauv cov tshuaj tiv thaiv uas muaj cov tshuaj tiv thaiv dej.
Kev Lag Luam Textile: PEG siv rau hauv kev ua cov ntaub ua cov roj nplua nyeem thiab cov neeg sawv cev tiav, txhim kho cov ntaub qhov kev xav, kev ruaj khov, thiab cov khoom zas xim.
Kev Lag Luam Khoom Noj: PEG yog siv los ua cov khoom ntub dej, cov khoom ruaj khov, thiab cov khoom ua kom tuab hauv cov khoom noj xws li cov khoom ci, khoom qab zib, thiab cov khoom noj mis nyuj, txhim kho cov qauv thiab lub neej txee.
Kev Siv Biomedical: PEGylation, tus txheej txheem ntawm kev txuas PEG saw hlau rau biomolecules, yog siv los hloov kho pharmacokinetics thiab biodistribution ntawm cov protein kho mob thiab nanoparticles, ua rau lawv lub sijhawm ncig thiab txo qis kev tiv thaiv kab mob.
HPMC thiab PEG pom cov ntawv thov dav dav thoob plaws hauv kev lag luam tshuaj, khoom noj, tshuaj pleev ib ce, kev tsim kho, thiab ntau yam lag luam, vim lawv cov khoom siv tau ntau yam thiab kev ua haujlwm.
