I-HPMC iyi-cotton cellulose ehlanzekile kakhulu njengento eluhlaza, ngaphansi kwezimo ze-alkali nge-etherification ekhethekile nokulungiswa.Impushana emhlophe noma emhlophe.I-HPMC iyancipha ngokuncipha kokuqukethwe kwe-methoxide, ukwanda kwephuzu le-gel, ukuncipha kokuncibilika kwamanzi nokuncipha komsebenzi ongaphezulu.
I-HPMC inekhono lokuqina, ukumelana nosawoti, impushana yomlotha ephansi, ukuzinza kwe-pH, ukugcinwa kwamanzi, ukuzinza kwe-dimensional, ukwakheka kwefilimu okuhle kakhulu, kanye nohlu olubanzi lokumelana nama-enzyme, ukuhlakazeka nokunamathela.
I-HPMC, i-Hydroxypropyl Methylcellulose izinhlobo ze-non-ionic cellulose ether, eziyimpushana emhlophe ukuya komhlophe, esebenza njenge-thickener, binder, ifilimu-yangaphambili, i-surfactant, i-colloid evikelayo, i-lubricant, i-emulsifier ne-suspension kanye nosizo lokugcina amanzi. Ngaphezu kwalokho, kunezinhlobo ze-cellulose ethers zibonisa izakhiwo ze-gelation eshisayo, ukungabi namandla kwe-metabolic, ukumelana nama-enzyme, iphunga eliphansi nokunambitha, nokuzinza kwe-PH.
Ngenxa yenqwaba yezakhiwo, i-HPMC ivamise ukusetshenziselwa ukufaka ezinye izithasiselo eziningi ngokugxila kancane, okwenza i-HPMC ibe isithasiselo esisebenza kahle kakhulu nesisebenzayo endaweni yokunamathela, ukwakhiwa, ukudla, imikhiqizo yasendlini, imithi nokunye.
