Hydroxypropyl methylcellulose (HPMC)ke motsoako o sebetsang ka bongata o sebelisoang haholo mefuteng e fapanengliindasterika lebaka la thepa ea eona e mengata.Karolo e 'ngoe ea bohlokoa e amang ts'ebetso ea HPMC ke bohloeki ba eona, bo ka amang viscosity ea eona haholo, ka lebaka leo, ts'ebeliso ea eona.Sengoliloeng sena se shebana le kamano lipakeng tsa bohloeki ba HPMC le viscosity, se fana ka leseli mabapi le litlamorao tsa eona makaleng a fapaneng.
HPMCle Bohlokoa ba eona:
HPMC, e nkiloeng ho selulose ea tlhaho, e na le liphetoho tsa lik'hemik'hale ho theha polima ea maiketsetso e nang le litšobotsi tse ikhethang.Motsoako ona o fumana ts'ebeliso ho tsa meriana, litlolo, kaho, le tse ling, ka lebaka la matla a eona a ho hola, ho emisa le ho etsa lifilimi.Leha ho le joalo, bohloeki ba HPMC bo hlaha e le ntlha ea bohlokoa e susumetsang ts'ebetso ena.
Kameho ea Bohloeki ho Viscosity:
Bohloeki bo bapala karolo ea bohlokoa ho tsebahatse viscosity ea tharollo ea HPMC.Maemo a phahameng a bohloeki ka kakaretso a lebisa liphellong tse tsitsitseng le tse ka tsejoang esale pele tsa viscosity.Litšila, joalo ka masalaselulose, e ka hlahisa mefuta e fapaneng ea viscosity, e amang ts'ebetso ea kakaretso ea lihlahisoa tse thehiloeng ho HPMC.

Litšobotsi tsa ho Suspension:
Bokhoni ba HPMC ba ho emisa likaroloana tse entsoeng ka metsi bo angoa ke bohloeki ba eona.Litšila li ka sitisa ho thehoa ha li-suspensions tse tsitsitseng, tse ka amang katleho ea meriana ea mokelikeli oa molomo le tse ling tse emisitsoeng.
