I-HPMC ingancibilika ku-solvent exutshwe namanzi abandayo kanye ne-organic matter ukuze kwakhiwe isisombululo se-viscous esisobala.Isixazululo esinamanzi sinomsebenzi ongaphezulu, ukukhanya okuphezulu kanye nokuzinza okuqinile.Ukuhlakazeka kwayo emanzini akuthintwa i-pH.Inomphumela wokujiya kanye ne-anti-fridge ku-shampoo nejeli yokugeza, futhi inokugcina amanzi kanye nezakhiwo ezinhle zokwenza ifilimu zezinwele nesikhumba.Ngokukhula okukhulu kwezinto zokusetshenziswa eziyisisekelo, i-cellulose (i-antifreeze thickener) inganciphisa kakhulu izindleko futhi izuze imiphumela emihle uma isetshenziswa ku-shampoo nejeli yokugeza.
I-hydroxypropyl methyl cellulose esheshayo yezinga lamakhemikhali nsuku zonke inezici ezilandelayo zomkhiqizo:
1. Ukusebenza kahle kakhulu kokugcinwa kwamanzi.I-HPMC inezici ze-hydrophilic.Ingakwazi ukugcina ukugcinwa kwamanzi okuphezulu emikhiqizweni yokunamathisela, ukunamathisela kanye nokunamathisela.
2. Amanzi abandayo asheshayo i-hydroxypropyl methylcellulose HPMC isebenzisa izinto zokusetshenziswa zemvelo, ezinokusebenza okuncane, ukucasuka okuphansi, ukuvikelwa kwemvelo nokuphepha.
3. I-PH izinzile uma kuqhathaniswa, futhi i-viscosity yesisombululo samanzi ngokuvamile izinzile ebangeni le-pH3.0 ukuya ku-11.0.
4. Isixazululo esinamanzi somkhiqizo sinomsebenzi ongaphezulu, i-emulsification, ukuvikelwa kwe-colloid kanye nokuzinza okuhlobene.Ukungezwani kwayo okungaphezulu kucishe kube ngu-2% kanti isisombululo esinamanzi singama-42-56dyn/cm.
5. Ukuqina nokuncibilika kwamanzi, kungancibilika ngokushesha emanzini abandayo, amanye ama-solvents e-organic kanye nezingxube ezinama-organic solvents.
6. Ukwandisa i-viscosity: lapho inani elincane lokuchithwa likhuphuka, isisombululo se-viscous esisobala sizokwakhiwa, esinezici zokusebenza okuzinzile nokucaca okuphezulu.I-solubility izoshintsha nge-viscosity.I-viscosity ephansi, i-degree enkulu yokuqedwa, engathuthukisa ngokuphumelelayo ukuzinza kokugeleza kwesistimu.
7. Ukumelana nosawoti okuhle kakhulu.I-HPMC iyi-polymer engeyona i-ionic, ezinzile kusixazululo se-aqueous electrolyte noma i-organic electrolyte.
8. I-Thermal Gelation: lapho isisombululo se-aqueous sishiswa ekushiseni okuthile, sizoba yi-opaque kuze kube yilapho kukhiqizwa isimo se-flocculation, esizokwenza ngokuphelele isisombululo silahlekelwe yi-viscosity yayo efanele.Nokho, izoshintshela esimweni sokuqala sesixazululo ngemva kokupholisa.Ngenkinga yejeli elishisayo, izinga lokushisa lixhomeke ikakhulukazi kuhlobo lomkhiqizo, ukuhlushwa kwesisombululo kanye nezinga lokushisa.
9. I-HPMC inezinye izici emkhakheni wokusetshenziswa kwamakhemikhali kwansuku zonke, njengezakhiwo ezinhle kakhulu zokwakha ifilimu, ukumelana okubanzi kwama-enzyme, ukuhlakazeka kanye nezakhiwo zokubopha.
