1. Hydroxypropyl methyl celluloseqhibilihang ka metsing a batang, metsi a chesang a qhibilihisitsoeng a tla kopana le mathata. Empa mocheso oa eona oa gelation metsing a chesang o phahame haholo ho feta oa methyl cellulose. Ho qhibiliha ha methyl cellulose metsing a batang le hona ho ntlafalitsoe haholo.
2. The viscosity ea hydroxypropyl methyl cellulose e amana le boima ba eona ba molek'hule, 'me boima bo boholo ba molek'hule ke ho ba le viscosity e phahameng. Mocheso o tla boela o ama viscosity ea eona, mocheso o eketseha, viscosity e fokotseha. Leha ho le joalo, viscosity ea mocheso o phahameng o tlase ho feta oa methyl cellulose. Tharollo e tsitsitse ha e bolokiloe mocheso oa kamore.
3. Hydroxypropyl methyl cellulose e tsitsitse ho acid le alkali, 'me tharollo ea eona ea metsi e tsitsitse haholo ka har'a pH = 2 ~ 12. Caustic soda le metsi a lime ha a na phello e kholo ho thepa ea eona, empa alkaline e ka potlakisa sekhahla sa ho qhibiliha le ho ntlafatsa viscosity ea pin. Hydroxypropyl methyl cellulose e na le botsitso ho matsoai a akaretsang, empa ha motsoako oa motsoako oa letsoai o phahame, viscosity ea hydroxypropyl methyl cellulose tharollo e atisa ho eketseha.
4. Ho bolokoa ha metsi a hydroxypropyl methyl cellulose ho itšetlehile ka palo ea eona e ekelitsoeng, viscosity, joalo-joalo Sekhahla sa ho boloka metsi tlas'a chelete e tšoanang ea ho eketsa e phahame ho feta ea methyl cellulose.
5. Ho khomarela ha hydroxypropyl methyl cellulose mohahong oa seretse ho phahame ho feta methyl cellulose.
6. Hydroxypropyl methyl cellulosee na le khanyetso e ntle ea enzyme ho feta methyl cellulose, mme monyetla oa ho senyeha ha enzymatic tharollong o tlase ho feta methyl cellulose.
