HPMC ni selile nziza cyane ya selile nkibikoresho fatizo, mubihe bya alkaline na etherification idasanzwe no kuyitegura. Ifu yera cyangwa yera.HPMC igabanuka hamwe no kugabanuka kwa vitamine, kwiyongera kwa gel, kugabanuka kwamazi no kugabanuka kwibikorwa byubutaka.
HPMC ifite ubushobozi bwo kubyimba, kurwanya umunyu, ifu yivu nkeya, ituze rya pH, kugumana amazi, guhagarara neza, gukora firime nziza, hamwe nubwinshi bwimisemburo ya enzyme, gutatanya no gufatira hamwe.
HPMC, Hydroxypropyl Methylcellulose yubwoko butari ionic selulose ether, nifu yifu yera kugeza ibara ryera, ikora nkibyimbye, binder, firime-yahoze, surfactant, irinda colloid, lubricant, emulsifier hamwe nubufasha bwo gufata amazi. Mubyongeyeho, hari ubwoko bwa ethers ya selile yerekana imiterere yubushyuhe bwumuriro, kutagira metabolike, kurwanya enzyme, impumuro nke nuburyohe, hamwe na PH ituje.
Bitewe nimitungo itabarika, HPMC ikoreshwa mugusimbuza izindi nyongeramusaruro nyinshi hamwe nubushakashatsi buke, bigatuma HPMC yongerera imbaraga zidasanzwe kandi nziza mubice byamavuta, ubwubatsi, ibiryo, ibikomoka murugo, imiti nibindi.
