IHydroxypropylmethylcellulose (HPMC) iyi-polymer eyenziwe ngokushintsha i-cellulose yemvelo.Inezinhlobonhlobo zezicelo zezimboni kwezemithi, ukudla, izimonyo, kanye nokwakha.I-HPMC i-nonionic cellulose ether encibilika kalula emanzini futhi ingakha isixazululo esisobala, esine-viscous esihlala sizinzile phezu kwebanga elibanzi le-pH.
Izici ze-HPMC zifaka:
1. Amandla aphezulu okugcina amanzi: I-HPMC ingakwazi ukumunca amanzi futhi iwabambe endaweni, iwenze abe wusizo njengesithako esijiyayo, i-emulsifier, nesinzinzisi ezinhlelweni eziningi.
2. Izakhiwo ezinhle zokwenza ifilimu: I-HPMC ingakha amafilimu abonisa izinto anamandla amahle emishini.Lokhu kuvumela ukuthi isetshenziswe ekukhiqizeni ama-capsules, ama-coatings neminye imikhiqizo.
3. Umsebenzi osezingeni eliphezulu: I-HPMC inezinto ezisebenza phezulu, ezivumela ukuthi isetshenziswe njenge-ejenti yokumanzisa kanye ne-disperse.
4. Ukuzinza okuhle kwe-thermal: I-HPMC izinzile emazingeni okushisa aphezulu futhi ingasetshenziswa ezinhlelweni ezidinga lokhu kusebenza.
5. Ukunamathela okuhle ezindaweni ezihlukahlukene: I-HPMC ingabophezela ezindaweni eziningi, iyenze ibe usizo ekukhiqizeni izinto zokunamathisela nezingubo.
Ukusetshenziswa kwe-HPMC ezimbonini ezahlukahlukene:
1. Umuthi: I-HPMC isetshenziswa kabanzi emalungiselelweni emithi njenge-binder, disintegrant, kanye nesilawuli se-viscosity.Itholakala kumaphilisi, amaphilisi kanye ne-liquid formulations.
2. Ukudla: I-HPMC isetshenziswa njenge-thickener, stabilizer kanye ne-emulsifier ekudleni.Ingasetshenziswa emikhiqizweni efana no-ayisikhilimu, iyogathi kanye nezingubo zesaladi.
3. Izimonyo: I-HPMC isetshenziswa kakhulu kuzimonyo njenge-thickener, emulsifier, kanye ne-ejenti yokwenza ifilimu.Ingasetshenziswa emikhiqizweni enjengama-creams, ama-lotions nama-shampoos.
4. Ukwakhiwa: I-HPMC iyisithako esiyinhloko ezintweni eziningi zokwakha ezifana nokunamathiswa kwamathayela, amapulastele asekelwe kusimende nodaka.Isebenza njenge-ejenti yokugcina amanzi, ithuthukisa ukusebenza kahle, futhi inikeza ukulawulwa okungcono kokunamathela nokuncipha.
Isilinganiso sereferensi yemboni ye-HPMC:
1. Ukugcinwa kwamanzi: Izinga lokugcinwa kwamanzi le-HPMC liwuhlaka olubalulekile olunquma ukusebenza kahle kwalo njengokuqina nokunamathela.Indawo inamazinga okubhekisela embonini angu-80-100%.
2. I-Viscosity: I-Viscosity iyipharamitha eyinhloko ekukhetheni i-HPMC yezinhlelo zokusebenza ezihlukahlukene.Izilinganiso zereferensi yemboni ye-viscosity zisukela ku-5,000 kuye ku-150,000 mPa.s.
3. Okuqukethwe kweqembu le-Methoxyl: Okuqukethwe kweqembu le-methoxyl le-HPMC kuthinta ukunyibilika kwayo, i-viscosity kanye nokuba khona kwayo.Isilinganiso sereferensi yemboni yokuqukethwe kwe-methoxy siphakathi kuka-19% no-30%.
4. Okuqukethwe kwe-Hydroxypropyl: Okuqukethwe kwe-hydroxypropyl kuthinta ukunyibilika kanye ne-viscosity ye-HPMC.Isilinganiso sereferensi yemboni sokuqukethwe kwe-hydroxypropyl siphakathi kuka-4% no-12%.
I-HPMC iyi-polymer eguquguqukayo enezicelo eziningi zezimboni.Izakhiwo zayo eziyingqayizivele ziyenza ifanelekele ukusetshenziswa kwezemithi, ukudla, izimonyo nokwakhiwa.Izilinganiso zezithenjwa zemboni zamapharamitha ahlukahlukene zisiza ekukhetheni ibanga elifanele le-HPMC lohlelo oluthile.
