Hypromellose, inozivikanwawo se hydroxypropyl methylcellulose (HPMC), i polymer yakagadzirwa kubva ku cellulose.Iyo inogadzirwa nemakemikari ekugadzirisa cellulose yechisikigo inowanikwa kubva muhuni pulp kana machira ekotoni kuburikidza nenzira inozivikanwa se etherification.Mukuita uku, iyo cellulose fiber inobatwa nemusanganiswa wepropylene oxide uye methyl chloride, izvo zvinotungamira mukuwedzerwa kwehydroxypropyl uye methyl mapoka kune cellulose mamorekuru.

Chigadzirwa chinobuda ipolymer inonyungudika nemvura inoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira mishonga, zvizorwa, zvigadzirwa zvekudya, uye zvekudya zvinowedzera.Hypromellose inowanikwa mumagiredhi akasiyana, ane huremu hwemamorekuru hwakasiyana uye madhigirii ekutsiva, zvichienderana nekushandiswa kwakarongwa.

Pakazara, hypromellose inoonekwa seyakachengetedzeka uye inoshivirirwa zvakanaka kana yakashandiswa sekurairwa.Inowanzo shandiswa seajenti yekupfekedza, inokora mumiriri, uye inodzikamisa muzvigadzirwa zvakawanda uye inokosheswa nekugona kwayo kuvandudza kugadzikana kwechigadzirwa, kuwedzera viscosity, uye kuwedzera mashandiro echigadzirwa.
