I-Hypromellose, eyaziwa nangokuthi i-hydroxypropyl methylcellulose (HPMC), i-polymer yokwenziwa etholakala ku-cellulose. Yenziwa ngokushintsha amakhemikhali i-cellulose yemvelo etholakala ku-pulp yokhuni noma imicu kakotini ngenqubo eyaziwa ngokuthi i-etherification. Kule nqubo, imicu ye-cellulose iphathwa ngenhlanganisela ye-propylene oxide ne-methyl chloride, okuholela ekwengezweni kwamaqembu e-hydroxypropyl nama-methyl kuma-molecule e-cellulose.

Umkhiqizo ovelayo uyi-polymer encibilika emanzini esetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi imithi, izimonyo, imikhiqizo yokudla, nezithako zokudla. IHypromellose itholakala emabangeni ahlukene, ngezisindo zamangqamuzana ahlukahlukene kanye namazinga okushintsha, kuye ngokusetshenziswa okuhlosiwe.

Sekukonke, i-hypromellose ithathwa njengesithako esiphephile futhi esibekezelelwa kahle uma sisetshenziswa njengoba kuyaliwe. Ivamise ukusetshenziswa njenge-ejenti enamathelayo, i-ejenti ejiyayo, kanye ne-stabilizer emikhiqizweni eminingi futhi ihlonishwa ngekhono layo lokuthuthukisa ukuqina komkhiqizo, ukwandisa i-viscosity, kanye nokuthuthukisa ukusebenza komkhiqizo.
