Hydroxypropyl methylcellulose (HPMC) ke polymer e feto-fetohang le e sebetsang ka mefuta-futa e sebelisoang liindastering tse fapaneng, ho kenyeletsoa meriana, lijo, kaho le litlolo. Motsoako o tsoa ho cellulose mme o fetotsoe ka ts'ebetso ea lik'hemik'hale ho ntlafatsa thepa ea eona.
1. Sebopeho sa lik'hemik'hale le thepa ea hydroxypropyl methylcellulose:
HPMC ke semi-synthetic polymer e fumanoang ka ho fetola selulose ea tlhaho ka ho eketsa propylene oxide le methylene chloride. The degree of substitution (DS) le molar substitution (MS) ke lintlha tsa bohlokoa tse khethollang thepa ea HPMC. Litekanyetso tsena li bonts'a boemo ba hydroxypropyl le methoxy substitution mokokotlong oa cellulose.
Sebopeho sa lik'hemik'hale sa HPMC se fa polymer mefuta e mengata e lakatsehang. Ke thepa ea hydrophilic e nang le bokhoni bo botle ba ho boloka metsi, e etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng moo taolo ea mongobo e leng bohlokoa. Ntle le moo, HPMC e na le thepa ea ho etsa lifilimi, e bohlokoa bakeng sa liindasteri tse kang tsa meriana le liphahlo.
2. Likopo tsa bongaka:
HPMC e sebelisoa haholo indastering ea meriana ka lebaka la biocompatibility, nontoxicity, le bokhoni ba ho fetola tokollo ea lithethefatsi. E sebelisoa hangata ha ho etsoa liforomo tsa litekanyetso tse tiileng tsa molomo joalo ka matlapa le li-capsules. Ho lokolloa ha lithethefatsi tse laoloang ho tsoa mefuteng ena ea litekanyetso ho finyelloa ka ho fetola viscosity le thepa ea ho ruruha ea HPMC.
Ntle le moo, HPMC e sebelisoa e le setlamo, sekoahelo, le sekoaelo sa filimi mefuteng ea matlapa. Litšobotsi tsa eona tsa ho etsa lifilimi li thusa ho nts'etsopele ea liphahlo tse matlafatsang botsitso ba lithethefatsi, tatso ea mask, le ho fana ka thepa e laoloang ea tokollo. Ho lumellana ha polymer le mefuta e fapaneng ea metsoako e sebetsang ea meriana (APIs) e etsa hore e be khetho e fapaneng bakeng sa baetsi ba lihlahisoa.
3. Indasteri ea kaho:
Lefapheng la kaho, HPMC e sebelisoa haholo joalo ka ntho e tiisang lihlahisoa tse thehiloeng ho samente. E ntlafatsa ho sebetsa le ho tsitsisa ha lirafshoa le li-plaster, ho fokotsa ho sagging le ho ntlafatsa ho khomarela. Lintho tse bolokang metsi tsa HPMC li thibela motsoako oa samente hore o se ke oa omella ka potlako, o lumella hore ho be le hydration e ntle ea likaroloana tsa samente le ntlafatso ea matla a ntlafetseng.
HPMC e boetse e sebelisoa ho likhomaretsi tsa lithaele, li-grouts le metsoako ea ho ikemela. Karolo ea eona lits'ebetsong tsena e kenyelletsa ho laola viscosity, ho fana ka nako e ntle e bulehileng, le ho ntlafatsa ts'ebetso e akaretsang ea thepa ea moaho.
4. Indasteri ea lijo:
HPMC e amohetsoe hore e sebelisoe indastering ea lijo joalo ka tlatsetso ea lijo (E464). Tabeng ena, e sebetsa e le motenya, stabilizer le emulsifier lijong tse fapaneng. HPMC e bohlokoa haholo bakeng sa bokhoni ba eona ba ho etsa li-gel, ho ntlafatsa sebopeho le ho tsitsisa foam mefuteng ea lijo.
Mehaho ea HPMC ea ho boloka metsi e etsa hore e be molemo lihlahisoa tsa baka, li-dessert tsa lebese le li-sauces. Ho phaella moo, thepa ea eona ea ho etsa lifilimi e ka sebelisoa ho hlahisa lifilimi tse jeoang le liphahlo ho ntlafatsa ponahalo le bophelo ba sethala sa lijo tse itseng.
5. Litlolo le lihlahisoa tsa tlhokomelo ea motho ka mong:
Indastering ea litlolo le tlhokomelo ea motho, HPMC e sebelisoa lihlahisoa tse fapaneng, ho kenyeletsoa litlolo, litlolo, li-shampoo le lihlahisoa tsa setaele sa moriri. Bokhoni ba eona ba ho etsa lifilimi bo thusa ho theha lesela le boreleli le sireletsang letlalong le moriring.
HPMC e nkoa e le ea bohlokoa bakeng sa karolo ea eona ea ho fetola sebopeho se teteaneng le rheology, ho fana ka sebopeho se lakatsehang le viscosity ho litlolo tsa litlolo. E boetse e thusa ho tsitsisa li-emulsions, ho thibela ho arohana ha mekhahlelo le ho ntlafatsa botsitso bo akaretsang ba litlolo.
6. Ts'ebetso le melemo:
Poloko ea Metsi: O mong oa melemo ea mantlha ea HPMC ke bokhoni ba eona bo botle ba ho boloka metsi. Thepa ena e bohlokoa bakeng sa lits'ebetso moo taolo ea mongobo e leng bohlokoa haholo, joalo ka meriana le lisebelisoa tsa kaho.
Tlhahiso ea Lifilimi: Thepa ea ho etsa filimi ea HPMC e thusa ho nts'etsopele ea liphahlo tse fanang ka tšireletso, ho lokolloa ho laoloang, le ho ntlafatsa aesthetics lits'ebetsong tse fapaneng.
Phetoho ea Thickening le Rheology: HPMC e tsebahala haholo ka bokhoni ba eona ba ho tenya litharollo le ho fetola thepa ea rheological ea metsoako. Sena se etsa hore e be ea bohlokoa indastering moo taolo ea viscosity e leng bohlokoa.
Biocompatibility: Lits'ebetsong tsa meriana le tsa litlolo, biocompatibility ea HPMC ke monyetla oa bohlokoa. Ka kakaretso e mamelloa hantle ke batho, e etsa hore e loketse ho sebelisoa lihlahisoa bakeng sa tsamaiso ea lihlooho kapa tsa molomo.
Ho feto-fetoha ha maemo: Ho feto-fetoha ha maemo ha HPMC ho bonahala mefuteng e mengata ea lits'ebetso liindastering tse fapaneng. Ho lumellana ha eona le lisebelisoa tse ling le boiketlo ba ho kenngoa ka har'a lihlahisoa li etsa hore e ratoe.
7. Liphephetso le maikutlo:
Hydrophilicity: Le hoja hydrophilicity ea HPMC e le molemo lits'ebetsong tse ngata, e ka hlahisa liphephetso mefuteng e itseng moo ho khathatseha ha metsi.
Temperature Sensitivity: Ts'ebetso ea HPMC e angoa ke mocheso mme ts'ebetso ea eona e ka fapana tlasa maemo a fapaneng a tikoloho. Baetsi ba liforomo ba tlameha ho nahana ka lintlha tsena ha ba theha liforomo.
Litšenyehelo: Maemong a mang, litšenyehelo tsa HPMC li ka nahanoa, haholo liindasteri tseo ho tsona ho nahanoang ka katleho ea litšenyehelo.
8. Qetello:
Hydroxypropyl methylcellulose ke polymer e feto-fetohang e bapalang karolo ea bohlokoa liindasteri tse 'maloa ho kenyelletsa le tsa meriana, kaho, lijo le litlolo. Motsoako oa eona o ikhethang oa thepa, ho kopanyelletsa le ho boloka metsi, thepa ea ho etsa lifilimi le ho feto-fetoha ha maemo, ho etsa hore e be motsoako oa bohlokoa mefuteng e fapaneng ea likopo. Ho sebetsa ha HPMC ho fana ka lithethefatsi, thepa ea kaho, lijo le mekhoa ea tlhokomelo ea botho e totobatsa bohlokoa ba eona mekhoeng ea morao-rao ea tlhahiso.
Ha indasteri e ntse e tsoela pele ho fetoha, tlhoko ea li-polymer tse sebetsang le tse tšepahalang joalo ka HPMC e kanna ea tsoela pele. Boiteko bo tsoelang pele ba lipatlisiso le nts'etsopele bo kanna ba ntlafatsa ts'ebetso le ts'ebeliso ea HPMC, ho netefatsa hore e tsoela pele ho sebetsa mafapheng a fapaneng. Qetellong, litlamorao le katleho ea hydroxypropyl methylcellulose li bonts'a tšusumetso ea lisebelisoa tse ncha tse ka bang le tsoelopele ea liindasteri tse fapaneng.
