Lintlha tsa Bohlokoa tse Amang Boleng ba Hydroxypropyl Methylcellulose
Boima ba Molek'hule
Boima ba molek'hule (MW) bo bolela boholo ba molek'hule ea AnxinCel®HPMC mme e bapala karolo ea bohlokoa ho khethollang viscosity le ho qhibiliha ha eona. Boima bo phahameng ba molek'hule HPMC e atisa ho ba le viscosity e phahameng, e leng molemo lits'ebetsong tse kang ho lokolloa ha lithethefatsi kapa e le ntho e teteaneng mekhoeng e sa tšoaneng.
Boima bo Tlase ba Molek'hule (LMW): Ho qhibiliha ka potlako, viscosity e tlaase, e loketseng haholoanyane bakeng sa likopo tse kang ho roala le ho etsa filimi.
Boima bo Phahameng ba Molek'hule (HMW): Ho qhibiliha butle-butle, viscosity e phahameng, e loketseng haholoanyane bakeng sa ho teteana, ho phunya, le mekhoa e laoloang ea ho lokolla lithethefatsi.
Degree of Substitution (DS)
Tekanyo ea ho nkela sebaka e bolela hore na lihlopha tsa hydroxyl mokokotlong oa cellulose li nkeloa sebaka ke lihlopha tsa methyl le hydroxypropyl. Ntho ena e ama boleng ba solubility le rheological ea polymer.
DS e tlase: Ho fokotsa ho qhibiliha ha metsi, matla a phahameng a gel.
DS e phahameng: Keketseho ea ho qhibiliha ha metsi, ho fokotsa matla a li-gel, le thepa ea tokollo e laoloang hamolemo ho litlhare.
Viscosity
Viscosity ke ntlha ea bohlokoa ho khethollang hore na HPMC e ka sebetsa hantle hakae ho thinya, ho tsitsisa, le lits'ebetsong tsa gelling. HPMC e nang le viscosity e phahameng e sebelisoa lits'ebetsong tse kang li-emulsions, suspensions, le hydrogels, athe limaraka tse tlase tsa viscosity li loketse lijo le litlatsetso tsa meriana.
Viscosity e tlase: E sebelisoa ka tloaelo lijong, tlhokomelong ea botho, le litlhahlobo tsa meriana bakeng sa ho etsa lifilimi le ho tlama.
Viscosity e phahameng: E sebelisoa ho lihlahisoa tse laoloang ke meriana, li-gel tse matla haholo, le li-thickeners lihlahisoa tsa indasteri.
Bohloeki
Boemo ba litšila, tse kang li-solvents tse setseng, letsoai la inorganic, le litšila tse ling, li ka ama haholo ts'ebetso ea AnxinCel®HPMC. Limaraka tse phahameng tsa bohloeki hangata lia hlokahala lits'ebetsong tsa meriana le tsa lijo.
Pharmaceutical Grade: Bohloeki bo phahameng, hangata bo tsamaisana le taolo e matla holim'a lihlahisoa tse setseng le litšila.
Sehlopha sa indasteri: Bohloeki bo tlaase, bo amohelehang bakeng sa lisebelisoa tse sa jeng kapa tse sa sebeliseng phekolo.
Solubility
The solubility ea HPMC ka metsing itšetlehile ka bobeli boima ba eona molek'hule le tekanyo ea ho nka sebaka. Ka tloaelo, HPMC e qhibiliha ka metsing a batang, e leng se etsang hore e be khetho e babatsehang bakeng sa mefuta e mengata ea lisebelisoa tse hlokang metsoako e thehiloeng metsing.
Tlase Sollubility: Ha e na ho qhibiliha hanyenyane, e sebelisetsoang mekhoa e laoloang ea tokollo.
Monyetla o phahameng: E qhibiliha haholoanyane, e loketse lits'ebetso tse hlokang ho qhibiliha kapele.
Thermal Stability
Ho tsitsa ha mocheso oa HPMC ke ntlha ea bohlokoa, haholo-holo liindastering tse kenyelletsang ho sebetsa ka mocheso o phahameng. Botsitso bo phahameng ba mocheso bo ka ba bohlokoa lits'ebetsong tse kang liphahlo tsa letlapa le indastering ea lijo.
Matla a Gel
Matla a gel a bolela bokhoni ba HPMC ba ho etsa gel ha e kopane le metsi. Matla a phahameng a gel a lakatsoa lits'ebetsong tse joalo ka lits'ebetso tsa phano ea lithethefatsi tse laoloang, 'me matla a tlase a li-gel hangata a ratoa lits'ebetsong tse kang ho emisoa le li-emulsions.
