Hydroxypropyl methylcellulose ni ether ya cellulose idafite ionic ikozwe muri cellulose karemano ya polymer binyuze mu buryo butandukanye bwa shimi. Ni ubwoko bw'ifu yera idafite impumuro, impumuro, kandi idahumanya, ibyimba mu mazi akonje kandi yitwa umuti wa colloidal usobanutse cyangwa ufite ibicu bike. Ifite imiterere yo gukurura, gufatanya, gukwirakwiza, gukurura, gukora filime, kuyihagarika, kuyikurura, kuyitera amenyo, kuyikora ku buso, kuyibungabunga no kuyirinda.
Hydroxypropyl methylcellulose nziza cyane ishobora gukemura neza ikibazo cyo kubika amazi mu gihe cy'ubushyuhe bwinshi. Mu bihe by'ubushyuhe bwinshi, cyane cyane mu bice bishyushye n'ibyumye ndetse n'imiterere y'ubutaka ku ruhande rw'izuba, HPMC hydroxypropyl methylcellulose nziza cyane irakenewe kugira ngo amazi akomeze kubika amazi mu buryo bwiza.
Hydroxypropyl methylcellulose nziza cyane ifite uburyo bungana. Amatsinda yayo ya methoxy na hydroxypropoxy akwirakwira ku buryo bungana ku ruhererekane rwa molekile ya cellulose, bishobora kongera atome za ogisijeni ku migozi ya hydroxyl na ether ndetse n'isano ry'amazi. Ubushobozi bwo guhuza no gukora imigozi ya hydrogen buhindura amazi yigenga mo amazi yigenga, bityo bikagenzura neza imyuka y'amazi iterwa n'ikirere gishyushye cyane kandi bigatuma amazi agumana amazi menshi.
