Hydroxypropyl methylcellulose ndi non-ionic cellulose ether yopangidwa kuchokera ku cellulose yachilengedwe ya polima kudzera munjira zingapo zama mankhwala.Ndi mtundu wa ufa woyera wopanda fungo, wopanda fungo, wopanda poizoni, womwe umatupa m'madzi ozizira ndipo umatchedwa clear or cloudy colloidal solution.Lili ndi katundu wa thickening, kumanga, kubalalika, emulsifying, filimu kupanga, suspending, adsorbing, gelling, pamwamba yogwira, kusunga chinyezi ndi kuteteza colloid.
Hydroxypropyl methylcellulose yabwino kwambiri imatha kuthetsa vuto la kusunga madzi pansi pa kutentha kwakukulu.M'nyengo yotentha kwambiri, makamaka m'madera otentha ndi owuma komanso zomangamanga zopyapyala kumbali yadzuwa, HPMC hydroxypropyl methylcellulose yapamwamba imafunika kuti madzi asungidwe bwino.
Hydroxypropyl methylcellulose yapamwamba imakhala yabwino kwambiri.Magulu ake a methoxy ndi hydroxypropoxy amagawidwa mofanana pamagulu a cellulose, omwe amatha kupititsa patsogolo maatomu a okosijeni pa hydroxyl ndi ether bond ndi mgwirizano wa madzi.Kutha kuphatikiza ndikupanga zomangira za haidrojeni kumasintha madzi aulere kukhala madzi omangika, potero amawongolera bwino kutuluka kwamadzi chifukwa cha kutentha kwanyengo ndikukwaniritsa kusungirako madzi ambiri.
