Hydroxypropyll methylcellulose ndi malo osakhala a cellulose ether opangidwa kuchokera ku cellulose yachilengedwe ya polymer kudzera njira zingapo zamankhwala. Ndiwo mtundu wa ufa wopanda fungo, wopanda mphamvu, womwe umatupa m'madzi ozizira ndipo umatchedwa solodial yankho la colloidal. Ili ndi katundu wa kukula, kumanga, kubalalitsa, emulsifteming, kupanga filimu, kuyimitsa, kupindika, pamtunda, kupitilira, wapamwamba, amakhala chinyezi, akuteteza Colloid.
Zabwino kwambiri hydroxpyl methylcellulose imatha kuthana bwino ndi vuto la madzi osungidwa kutentha kwambiri. Mu nyengo yotentha nyengo, makamaka m'malo otentha komanso owuma komanso zowonda kwambiri padzuwa, vpmc hydroxypyulose ya kusungidwa kwamadzi kwa slorry.
Hydroxypypypyl methylcellulose imafanana. Magulu ake a methoxy ndi hydroxyprophoxy amagawidwa mogwirizana ndi ma cellulose molecula ophatikizika, omwe amatha kukulitsa ma atomu a oxygen pa hydroxyl ndi mayanjano amadzi. Kutha kuphatikiza ndi kupanga ma hydrogen kumatembenuza madzi osakhazikika m'madzi omangidwa, potero kumawongolera madzi oyambitsidwa ndi kutentha kwa kutentha kwambiri komanso kukwaniritsa kutentha kwa madzi.
