Hydroxypropyl methyl cellulose (HPMC) ke polymer e seng ionic, ether e seng ea ionic cellulose e entsoeng ka selulose ea tlhaho ea polymer. Sehlahisoa ha se na monko, ha se na tatso, se se nang chefo e tšoeu, se ka qhibiliha ka metsing a batang ho etsa tharollo e hlakileng ea viscous, e nang le thickening, bonding, qhala, emulsifying, filimi-forming, suspending, adsorbing, gelling, holim'a mosebetsi, likarolo tse joalo. joalo ka ho boloka mongobo le li-colloids tse sireletsang.
HPMC ea Grade instant e sebelisoa haholo ho lik'hemik'hale tsa masela, lihlahisoa tsa ho hloekisa lik'hemik'hale tsa letsatsi le letsatsi, litlolo le likarolo tse ling; joalo ka shampoo, ho hlatsoa 'mele, ho hloekisa sefahleho, lotion, tranelate, gel, toner, conditioner ea moriri, lihlahisoa tsa setaele, sesepa sa meno, mathe, metsi a bubble ea ho bapala, jj.
Litšobotsi tsa sehlahisoa tsa sehlopha sa letsatsi le letsatsi sa hydroxypropyl methyl cellulose li kenyelletsa haholo:
1. Lisebelisoa tsa tlhaho tse tala, ho halefa ho fokolang, ts'ebetso e bonolo, polokeho le ts'ireletso ea tikoloho;
2. Metsi-solubility le thickening: e ka qhibiliha ka metsing a batang hang-hang, e qhibiliha ka har'a metsoako e meng ea lintho tse phelang le motsoako oa metsi le metsoako ea tlhaho;
3. Thickening le viscosity-e ntseng e eketseha: keketseho e nyenyane ea ho qhibiliha e tla theha tharollo e hlakileng ea li-viscous, pepeneneng e phahameng, ts'ebetso e tsitsitseng, liphetoho tsa solubility ka viscosity, ho fokotseha ha viscosity, ho feta ho qhibiliha; ka katleho ho ntlafatsa botsitso ba ho phalla ha tsamaiso;
4. Ho hanyetsa letsoai: HPMC ke polymer e seng ea ionic, e batlang e tsitsitse ka litharollo tse nang le metsi a letsoai la tšepe kapa li-electrolyte tsa organic;
5. Ts'ebetso ea holim'a metsi: tharollo ea metsi ea sehlahisoa e na le ts'ebetso ea holim'a metsi, 'me e na le mesebetsi le thepa ea emulsification, colloid e sireletsang le botsitso bo lekanyelitsoeng; tsitsipano ea holim'a metsi ke: 2% tharollo ea metsi ke 42-56dyn / cm;
6. PH botsitso: viscosity ea tharollo ea metsi e tsitsitse ka har'a mefuta ea PH3.0-11.0;
7. Phello ea ho boloka metsi: thepa ea hydrophilic ea HPMC e ka eketsoa ho lihlahisoa tse senyehileng, tsa peista le tsa pasty ho boloka phello e phahameng ea ho boloka metsi;
8. Thermal gelation: Ha tharollo ea metsi e futhumetse mocheso o itseng, e fetoha opaque ho fihlela e theha (poly) flocculation state, e leng se etsang hore tharollo e lahleheloe ke viscosity ea eona. Empa ka mor'a ho pholile, e tla fetoha boemo ba pele ba tharollo hape. Mocheso oo ketsahalo ea gel e hlahang ho oona o itšetlehile ka mofuta oa sehlahisoa, mahloriso a tharollo le tekanyo ea mocheso;
9. Litšobotsi tse ling: thepa e babatsehang ea ho etsa lifilimi, le mefuta e mengata ea ho hanyetsa li-enzyme, ho arohana le ho kopana, joalo-joalo.
