Hydroxypropyl methylcellulose (HPMC) ke nonionic cellulose ether e sebelisoang haholo lits'ebetsong tse fapaneng tsa indasteri le tsa meriana. Mesebetsi ea eona e ka sehloohong e kenyelletsa thickener, filimi ea pele, stabilizer, emulsifier, e emisang le sekhomaretsi. HPMC e sebelisoa haholo indastering ea meriana, ea litlolo, ea lijo, ea kaho le liindasteri tse ling. Tšebeliso ea eona e itšetlehile ka sebaka se itseng sa kopo, phello e hlokahalang ea ts'ebetso, lisebelisoa tse ling tsa tlhahiso le litlhoko tse khethehileng tsa taolo.
1. Tšimo ea meriana
Litokisetsong tsa meriana, HPMC e atisa ho sebelisoa e le moemeli oa nako e telele, thepa ea ho roala, filimi ea pele le karolo ea capsule. Matlapeng, ts'ebeliso ea HPMC hangata e lipakeng tsa 2% le 5% ea boima ba 'mele ho laola sekhahla sa tokollo ea moriana. Bakeng sa matlapa a sa khaotseng, tšebeliso e ka ba holimo, esita le ho fihla ho 20% kapa ho feta, ho netefatsa hore moriana o ka lokolloa butle-butle ka nako e telele. Joalo ka thepa ea ho roala, ts'ebeliso ea HPMC hangata e lipakeng tsa 3% le 8%, ho latela botenya bo hlokahalang le litlhoko tsa ts'ebetso.
2. Indasteri ea Lijo
Lefapheng la lijo, HPMC e atisa ho sebelisoa e le motenya, emulsifier, moemeli oa ho emisa, joalo-joalo E sebelisoa e le sebaka sa mafura lijong tse tlaase-khalori hobane e ka fana ka tatso le sebopeho se kang mafura. Chelete e sebelisoang lijong hangata e pakeng tsa 0.5% le 3%, ho itšetlehile ka mofuta le sebopeho sa sehlahisoa. Ka mohlala, ka lino, li-sauces kapa lihlahisoa tsa lebese, palo ea HPMC e sebelisoang hangata e tlaase, e ka bang 0.1% ho isa ho 1%. Lijong tse ling tse hlokang ho eketsa viscosity kapa ho ntlafatsa sebopeho, joalo ka li-noodle kapa lihlahisoa tse halikiloeng, palo ea HPMC e sebelisitsoeng e ka ba holimo, hangata lipakeng tsa 1% le 3%.
3. Tšimo ea Litlolo
Ka litlolo, HPMC e sebelisoa haholo e le setenya, stabilizer le filimi ea pele ea litlolo, litlolo, li-shampoo, meriti ea mahlo le lihlahisoa tse ling. Tekanyetso ea eona hangata ke 0.1% ho isa ho 2%, ho latela litlhoko tsa viscosity ea sehlahisoa le litšobotsi tsa lisebelisoa tse ling. Litlolong tse ling tse ikhethileng, joalo ka lihlahisoa tsa tlhokomelo ea letlalo kapa litlolo tse sireletsang letlalo letsatsing tse hlokang ho etsa filimi, palo ea HPMC e sebelisitsoeng e ka ba holimo ho netefatsa hore sehlahisoa se etsa lesela le ts'ireletso le ts'oanang letlalong.
4. Lisebelisoa tsa mohaho
Ka thepa ea kaho, HPMC e sebelisoa haholo lihlahisoa tse kang samente, lihlahisoa tsa gypsum, lipente tsa latex le li-adhesives tsa lithaele ho ntlafatsa ts'ebetso ea kaho ea thepa, ho eketsa nako e bulehileng, le ho ntlafatsa thepa ea ho thibela ho senya le ho thibela ho phunyeha. Palo ea HPMC e sebelisoang linthong tsa mohaho hangata e pakeng tsa 0.1% le 1%, ho itšetlehile ka litlhoko tsa moralo. Bakeng sa seretse sa samente kapa lisebelisoa tsa gypsum, palo ea HPMC ka kakaretso ke 0.2% ho 0.5% ho netefatsa hore thepa e na le ts'ebetso e ntle ea kaho le rheology. Ka pente ea latex, palo ea HPMC hangata ke 0.3% ho isa ho 1%.
5. Melawana le ditekanyetso
Linaha le libaka tse fapaneng li na le melao le litekanyetso tse fapaneng tsa tšebeliso ea HPMC. Lefapheng la lijo le meriana, tšebeliso ea HPMC e tlameha ho latela lipehelo tsa melaoana e amehang. Ka mohlala, EU le United States, HPMC e tsejoa ka ho pharaletseng e le e sireletsehileng (GRAS), empa tšebeliso ea eona e ntse e hloka ho laoloa ho latela lihlopha tse itseng tsa lihlahisoa le lisebelisoa. Libakeng tsa kaho le litlolo, leha ts'ebeliso ea HPMC e sa ipapise le lithibelo tse tobileng tsa taolo, phello e ka bang teng tikolohong, polokeho ea sehlahisoa le bophelo bo botle ba bareki e ntse e hloka ho nahanoa.
Ha ho na tekanyetso e tsitsitseng ea palo ea HPMC e sebelisitsoeng. E itšetlehile haholo ka boemo bo khethehileng ba ts'ebeliso, liphello tse hlokahalang tsa ts'ebetso, le ho hokahanya ha metsoako e meng ea tlhahiso. Ka kakaretso, palo ea HPMC e sebelisitsoeng e tloha ho 0.1% ho isa ho 20%, 'me boleng bo khethehileng bo hloka ho lokisoa ho latela moralo oa moralo le litlhoko tsa taolo. Lits'ebetsong tsa 'nete, basebetsi ba R&D hangata ba etsa litokiso ho latela lintlha tsa liteko le boiphihlelo ho fihlela ts'ebeliso e ntle ka ho fetesisa le ho baballa litšenyehelo. Ka nako e ts'oanang, ts'ebeliso ea HPMC e tlameha ho ipapisa le litekanyetso le melaoana ea indasteri ho netefatsa polokeho le tumellano ea sehlahisoa.
