Hydroxypropyl methylcellulose (HPMC) shine ether cellulose wanda aka samo daga cellulose na halitta. Na'urar roba ce, mai narkewar ruwa, wacce ba ta ionic polymer wacce aka saba amfani da ita a masana'antu daban-daban kamar gini, magunguna, abinci, kayan kwalliya, da masaku.

Ana samar da HPMC ta hanyar canza cellulose ta hanyar sinadarai tare da propylene oxide da methyl chloride don gabatar da ƙungiyoyin hydroxypropyl da methyl a cikin kwayoyin cellulose. Matsayin maye gurbin (DS) na HPMC yana nufin adadin hydroxypropyl da ƙungiyoyin methyl a kowace rukunin anhydroglucose (AGU) na cellulose.

HPMC yana da kaddarori da yawa waɗanda ke sa shi amfani a aikace-aikace daban-daban. Yana da narkewa a cikin ruwa, yana samar da bayani mai tsabta, kuma yana da kyakkyawan kwanciyar hankali na thermal. Hakanan yana da kwanciyar hankali a ƙarƙashin yanayin al'ada na zazzabi da pH kuma baya rubewa cikin sauƙi. HPMC hygroscopic ne, wanda ke nufin zai iya sha da riƙe danshi. Ba mai guba ba ne, ba mai ban haushi ba, kuma ba allergenic ba, wanda ya sa ya zama lafiya don amfani a yawancin aikace-aikace.

A cikin masana'antar gine-gine, ana amfani da HPMC azaman mai kauri, ɗaure, da mai riƙe ruwa a cikin samfuran tushen siminti, adhesives na tayal, filasta, da sauran kayan gini. A cikin masana'antar harhada magunguna, ana amfani da HPMC azaman ɗaure, tarwatsewa, da tsohon fim a cikin ƙirar kwamfutar hannu da capsule.
