IHydroxypropyl methylcellulose (HPMC) i-nonionic cellulose ether esetshenziswa kabanzi ezinhlotsheni ezihlukene zezimboni nezamakhemisi. Imisebenzi yayo eyinhloko ihlanganisa i-thickener, ifilimu yangaphambili, i-stabilizer, i-emulsifier, i-ejenti yokumisa nokunamathisela. I-HPMC isetshenziswa kabanzi embonini yezemithi, yezimonyo, ezokudla, ezakhiweni nakwezinye izimboni. Ukusetshenziswa kwayo kuncike emkhakheni othile wohlelo lokusebenza, umphumela odingekayo wokusebenza, ezinye izithako zokwakheka kanye nezidingo ezithile zokulawula.
1. Inkundla yezemithi
Emalungiselelweni emithi, i-HPMC ivame ukusetshenziswa njenge-ejenti ekhishwa isikhathi eside, izinto zokumboza, ifilimu yangaphambili kanye nengxenye ye-capsule. Kumaphilisi, ukusetshenziswa kwe-HPMC ngokuvamile kuphakathi kuka-2% no-5% wesisindo esiphelele ukulawula izinga lokukhululwa lomuthi. Kumaphilisi akhishwa isikhathi eside, ukusetshenziswa kungase kube phezulu, kuze kufike ku-20% noma ngaphezulu, ukuze kuqinisekiswe ukuthi umuthi ungakhululwa kancane kancane esikhathini eside. Njengento yokwemboza, ukusetshenziswa kwe-HPMC kuvame ukuba phakathi kuka-3% no-8%, kuye ngogqinsi oludingekayo kanye nezidingo zokusebenza.
2. Imboni Yokudla
Embonini yokudla, i-HPMC ivame ukusetshenziswa njenge-thickener, emulsifier, i-ejenti yokumisa, njll. Isetshenziswa njengengxenye yamafutha ekudleni okunekhalori ephansi ngoba inganikeza ukunambitheka okufana namafutha kanye nesakhiwo. Inani elisetshenziswa ekudleni ngokuvamile liphakathi kuka-0.5% no-3%, kuye ngohlobo nokwakheka komkhiqizo. Isibonelo, eziphuzweni, kumasoso noma emikhiqizweni yobisi, inani le-HPMC elisetshenziswayo ngokuvamile liphansi, cishe ngo-0.1% kuya ku-1%. Kokunye ukudla okudinga ukukhulisa i-viscosity noma ukuthuthukisa ukuthungwa, njengama-noodle asheshayo noma imikhiqizo ebhakiwe, inani le-HPMC elisetshenzisiwe lingase libe phezulu, ngokuvamile phakathi kuka-1% no-3%.
3. Inkundla yezimonyo
Kwezimonyo, i-HPMC isetshenziswa kabanzi njenge-thickener, stabilizer kanye nefilimu yangaphambili kuma-lotions, okhilimu, ama-shampoos, izithunzi zamehlo neminye imikhiqizo. Umthamo wawo ngokuvamile u-0.1% kuya ku-2%, kuye ngezidingo ze-viscosity zomkhiqizo kanye nezici zezinye izithako. Kwezinye izimonyo ezithile, njengemikhiqizo yokunakekelwa kwesikhumba noma izikhilimu zelanga ezidinga ukwakha ifilimu, inani le-HPMC elisetshenzisiwe lingase libe phezulu ukuze kuqinisekiswe ukuthi umkhiqizo wenza ungqimba oluvikelayo olufanayo esikhumbeni.
4. Izinto zokwakha
Ezimpahleni zokwakha, i-HPMC isetshenziswa kakhulu emikhiqizweni efana nosimende, imikhiqizo yegypsum, opende be-latex nezinamatheliso zamathayili ukuze kuthuthukiswe ukusebenza kokwakhiwa kwezinto zokwakha, ukwelula isikhathi esivulekile, kanye nokwenza ngcono izakhiwo zokulwa nokusagiga kanye nokunqanda ukuqhekeka. Inani le-HPMC elisetshenziswa ezintweni zokwakha ngokuvamile liphakathi kuka-0.1% no-1%, kuye ngezidingo zokwakhiwa. Ngodaka lukasimende noma izinto zegypsum, inani le-HPMC livamise ukuba ngu-0.2% kuya ku-0.5% ukuze kuqinisekiswe ukuthi impahla inokusebenza okuhle kokwakhiwa kanye ne-rheology. Kupende we-latex, inani le-HPMC livamise ukuba ngu-0.3% kuya ku-1%.
5. Imithethonqubo kanye namazinga
Amazwe ahlukene nezifunda zinemithethonqubo namazinga ahlukene okusetshenziswa kwe-HPMC. Emkhakheni wokudla nemithi, ukusetshenziswa kwe-HPMC kumele kuhambisane nezinhlinzeko zemithethonqubo efanele. Isibonelo, e-EU nase-United States, i-HPMC yaziwa kabanzi njengephephile (GRAS), kodwa ukusetshenziswa kwayo kusadinga ukulawulwa ngokuya ngezigaba zomkhiqizo ezithile kanye nezinhlelo zokusebenza. Emkhakheni wokwakha kanye nezimonyo, nakuba ukusetshenziswa kwe-HPMC kungaphansi kwemikhawulo eqondile yokulawula, umthelela ongaba khona endaweni ezungezile, ukuphepha komkhiqizo kanye nempilo yabathengi kusadingeka kucatshangelwe.
Alikho izinga elimisiwe lenani le-HPMC elisetshenzisiwe. Kuncike kakhulu esimweni sohlelo oluthile, emiphumeleni edingekayo yokusebenza, kanye nokuhlanganiswa kwezinye izithako zokwakheka. Ngokuvamile, inani le-HPMC elisetshenzisiwe lisuka ku-0.1% liye ku-20%, futhi inani elithile lidinga ukulungiswa ngokuya ngedizayini yokubunjwa kanye nezidingo zokulawula. Kuzinhlelo zokusebenza zangempela, abasebenzi be-R&D bavamise ukwenza izinguquko ngokusekelwe kudatha yokuhlola nolwazi ukuze bathole umphumela wokusebenzisa ongcono kakhulu kanye nokusebenza ngempumelelo kwezindleko. Ngesikhathi esifanayo, ukusetshenziswa kwe-HPMC kufanele kuhambisane namazinga nemithetho yemboni efanele ukuze kuqinisekiswe ukuphepha nokuhambisana komkhiqizo.
