I-HPMC ingancibilikiswa ku-solvent exutshwe namanzi abandayo kanye nezinto eziphilayo ukuze kwakheke isixazululo esibonakalayo esiqinile. Isixazululo samanzi sinomsebenzi wobuso, ukukhanya okuphezulu kanye nokuqina okuqinile. Ukuncibilika kwayo emanzini akuthinteki yi-pH. Inemiphumela yokujiya kanye nokulwa nokuqandisa ku-shampoo kanye ne-shower gel, futhi inokugcinwa kwamanzi kanye nezakhiwo ezinhle zokwakha ifilimu yezinwele nesikhumba. Ngokwanda okukhulu kwezinto eziyisisekelo zokusetshenziswa, i-cellulose (i-antifreeze thickener) inganciphisa kakhulu izindleko futhi ithole imiphumela emihle uma isetshenziswa ku-shampoo kanye ne-shower gel.
I-hydroxypropyl methyl cellulose ye-instant chemical water grade yansuku zonke inezici ezilandelayo zomkhiqizo:
1. Ukusebenza okuhle kakhulu kokugcinwa kwamanzi. I-HPMC inezici ezithinta amanzi. Ingagcina ukugcinwa kwamanzi okuphezulu emikhiqizweni ye-paste, paste kanye ne-paste.
2. I-hydroxypropyl methylcellulose esheshayo yamanzi abandayo i-HPMC isebenzisa izinto zokusetshenziswa zemvelo, ezisebenza kahle, ezicasulayo kancane, ezivikela imvelo kanye nokuphepha.
3. I-PH izinzile, futhi i-viscosity yesisombululo samanzi ivame ukuqina kusukela ku-pH3.0 kuya ku-11.0.
4. Isixazululo samanzi somkhiqizo sinomsebenzi wobuso, i-emulsification, ukuvikelwa kwe-colloid kanye nokuqina okulinganiselwe. Ukucindezeleka kobuso baso kucishe kube ngu-2% kanti isixazululo samanzi singama-42-56dyn/cm.
5. Njengoba iqina futhi incibilika emanzini, ingancibilika ngokushesha emanzini abandayo, kwezinye izinyibilikisi eziphilayo kanye nezingxube ezinezinyibilikisi eziphilayo.
6. Khulisa i-viscosity: lapho inani elincane lokuncibilika likhuliswa, kuzokwakhiwa isixazululo esicacile esiqinile, esinezici zokusebenza okuzinzile kanye nokucaca okuphezulu. Ukuncibilika kuzoshintsha ngokuncibilika. Uma i-viscosity iphansi, kulapho izinga lokuncibilika liba likhulu, okungathuthukisa ngempumelelo ukuzinza kokugeleza kohlelo.
7. Ukumelana okuhle kakhulu nosawoti. I-HPMC iyi-polymer engeyona i-ionic, ezinzile kakhulu kwisisombululo samanzi se-electrolyte ephilayo noma i-electrolyte ephilayo.
8. I-gelation yokushisa: lapho isixazululo samanzi sishiswa kufikela ezingeni lokushisa elithile, sizoba opaque kuze kube yilapho kukhiqizwa isimo sokugeleza, okuzokwenza ngokuphelele isixazululo silahlekelwe yi-viscosity yaso efanele. Kodwa-ke, sizoshintsha sibe yisimo sesixazululo sokuqala ngemva kokupholisa. Ngenkinga ye-gel yokushisa, izinga lokushisa lincike kakhulu ohlotsheni lomkhiqizo, ukuhlushwa kwesisombululo kanye nezinga lokushisa.
9. I-HPMC inezinye izakhiwo emkhakheni wokusetshenziswa kwamakhemikhali kwansuku zonke, njengezakhiwo ezinhle kakhulu zokwakha ifilimu, ukumelana okukhulu kwama-enzyme, izakhiwo zokuhlakazeka kanye nezakhiwo zokubopha.
