Hydroxypropyl methylcellulose (HPMC) ke lisebelisoa tse ngata tse sebelisoang haholo meriana, lijo, litlolo, thepa ea mohaho le masimo a mang. Ke ether e seng ea ionic cellulose e fumanoang ka phetoho ea lik'hemik'hale ea cellulose ea tlhaho, 'me sebopeho sa eona sa molek'hule se na le hydroxypropyl le methyl substituents. Litšobotsi tsena tsa sebopeho li fa HPMC thepa e mengata e ikhethang, e etsa hore e sebetse hantle lits'ebetsong tse fapaneng.
1. Excellent viscosity tokiso le thickening thepa
HPMC e na le solubility e ntle ka tharollo ea metsi 'me e ka theha litharollo tse phahameng tsa viscosity. Litšobotsi tsa eona tsa viscosity li ka laoloa ka ho fetola boima ba limolek'hule le tekanyo ea ho fetola. Sena se etsa hore HPMC e be setei se tloahelehileng se sebelisoang haholo le moemeli oa gelling liindastering tse ngata. Mohlala, indastering ea lijo, HPMC e ka sebelisoa ho tenya ice cream, li-sauces le lino tse tahang ho ntlafatsa tatso le sebopeho.
2. Lintho tse tsitsitseng tsa ho etsa lifilimi
HPMC e ka etsa lifilimi tse pepeneneng le tse thata libakeng tse fapaneng. Thepa ena ea ho etsa filimi ke ea bohlokoa ka ho khetheha lefapheng la bongaka. Lefapheng la meriana, HPMC e atisa ho sebelisoa bakeng sa ho roala letlapa, e ka khonang ho arola ka katleho ho kopana pakeng tsa lithethefatsi le tikoloho ea ka ntle le ho ntlafatsa botsitso le ho lokolloa ha lithethefatsi. Ho phaella moo, ka litlolo, HPMC e ka sebelisoa e le moemeli oa ho etsa lifilimi bakeng sa limaske tsa sefahleho le lihlahisoa tsa tlhokomelo ea letlalo ho ntlafatsa phihlelo ea sehlahisoa.
3. Molemo oa ho fanyeha le thepa ea emulsification
HPMC e na le bokhoni bo babatsehang ba ho fanyeha le ho emulsification, e ka tsitsang tsamaiso ea ho hasana le ho thibela sedimentation ea likaroloana le stratification. Ka indasteri ea ho roala, HPMC, e le motenya le stabilizer, e ka thibela sedimentation ea li-pigments le ho ntlafatsa ho tšoana le thepa ea rheological ea liphahlo. Ka indasteri ea lijo, HPMC e ka tsitsisa li-emulsion, ea thibela karohano ea metsi le oli, 'me ea ntlafatsa sebopeho le tatso ea lihlahisoa.
4. Biocompatibility le polokeho
HPMC e tsoa ho selulose ea tlhaho 'me e na le biocompatibility e ntle le polokeho. Ha e monoe ke tsamaiso ea tšilo ea lijo 'meleng ebile ha e bake liphetoho tse chefo. Sena se etsa hore HPMC e sebelisoe haholo indastering ea meriana le ea lijo. Ka mohlala, litokisetsong tsa meriana, HPMC e atisa ho sebelisoa ha ho etsoa litokisetso tse tsitsitseng, matlapa le li-capsules ho netefatsa ho lokolloa ha lithethefatsi ka mokhoa o sireletsehileng le o sebetsang. Indastering ea lijo, HPMC e amohetsoe joalo ka tlatsetso ea lijo 'me e sebelisoa haholo lijong tse kang bohobe, likuku le lihlahisoa tsa lebese.
5. Thermal colloid thepa
HPMC e na le thepa e ikhethang ea colloid ea mocheso, ke hore, e etsa gel ha e futhumala 'me e qhibiliha hape ka mor'a ho pholile. Thepa ena e etsa hore HPMC e sebetse hantle lits'ebetsong tse ling tse ikhethang. Ka mohlala, litokisetsong tsa meriana, HPMC e ka sebelisoa bakeng sa ho kenyelletsa le ho lokolla taolo ea lithethefatsi tse thibelang mocheso. Indastering ea lijo, HPMC e ka sebelisoa ha ho etsoa lijo tse tšetsoeng mocheso ho ntlafatsa sebopeho le botsitso ba lihlahisoa.
6. Ho feto-fetoha ha pH ka bophara
HPMC e na le ts'ebetso e tsitsitseng ka mefuta e mengata ea pH, e leng se e nolofalletsang ho boloka mesebetsi ea eona e teteaneng, e tsitsitseng le ea ho etsa lifilimi libakeng tse sa tšoaneng tsa asiti kapa alkaline. Ka mohlala, ka thepa ea mohaho, HPMC e ka sebelisoa bakeng sa ho tiisa le ho boloka metsi a thepa e thehiloeng ho samente le ea gypsum, ho ntlafatsa ts'ebetso ea kaho le ho tšoarella.
7. Tšireletso le ts'ireletso ea tikoloho
HPMC e tsoa mehloling ea selulose ea tlhaho e ka nchafatsoang hape e na le biodegradability e ntle le botsoalle ba tikoloho. Boemong ba tlhokomeliso e ntseng e eketseha ea tikoloho kajeno, HPMC, joalo ka boitsebiso bo tsitsitseng, e fumane tlhokomelo le ts'ebeliso e eketsehileng. Ka mohlala, ka liaparo tsa tikoloho le thepa ea mohaho, HPMC, e le motenya oa tlhaho le stabilizer, e nkela sebaka sa lisebelisoa tsa tlhaho tsa lik'hemik'hale tsa lik'hemik'hale le ho fokotsa tšilafalo ea tikoloho.
Hydroxypropyl methylcellulose (HPMC) e na le tebello e pharaletseng ea ts'ebeliso le likarolo tsa bohlokoa lefapheng la meriana, lijo, litlolo, thepa ea mohaho, joalo-joalo ka lebaka la taolo ea eona e babatsehang ea viscosity, sebopeho sa filimi, ho emisoa, emulsification, biocompatibility, thermal colloidization, ho ikamahanya le maemo a pH ka bophara. litšobotsi tsa tšireletso ea tikoloho. Ka tsoelopele e tsoelang pele ea mahlale le thekenoloji le ntlafatso ea litlhoko tsa batho bakeng sa bophelo bo botle le ts'ireletso ea tikoloho, sebaka sa ts'ebeliso ea HPMC se tla tsoela pele ho hola le ho bapala karolo e kholoanyane.
