Kusiyanitsa pakati pa hydroxypropyl methylcellulose yeniyeni ndi yotsika ndikwambiri ndipo kumakhudza kuyenerera kwawo pamagwiritsidwe osiyanasiyana. HPMC yeniyeni, yokhala ndi chiyero chambiri, kapangidwe kake kosasinthika, kupanga zapamwamba, komanso magwiridwe antchito odalirika, ndikofunikira pamapulogalamu omwe amafunikira kulondola komanso chitetezo. HPMC yotsika, kumbali ina, ndi zonyansa zake, katundu wosagwirizana, ndi kusowa kwa malamulo oyendetsera ntchito, kumayambitsa zoopsa zomwe zingasokoneze ubwino ndi mphamvu za mapeto.
M'mafakitale monga opanga mankhwala, zomangamanga, chakudya, ndi zodzoladzola, kusankha kwamtundu wa HPMC ndikofunikira. Kuwonetsetsa kugwiritsidwa ntchito kwa HPMC yeniyeni sikumangowonjezera magwiridwe antchito komanso kuonetsetsa kuti zikutsatira mfundo zachitetezo, ndikuteteza thanzi la ogula ndi chitetezo. Opanga ndi ogula ayenera kukhala tcheru posankha HPMC yapamwamba kwambiri kuti asunge kukhulupirika ndi kudalirika kwa zinthu zawo.
