IHypromellose, ekwabizwa ngokuba yi-hydroxypropyl methylcellulose (HPMC), yipolymer eyenziweyo evela kwiselulosi.Yenziwa ngokuguqula ngokwekhemikhali iselulosi yendalo efunyenwe kwintlama yomthi okanye kwimicu yomqhaphu ngenkqubo eyaziwa ngokuba yi-etherification.Kule nkqubo, i-cellulose fibers iphathwa ngokudibanisa i-propylene oxide kunye ne-methyl chloride, ekhokelela ekongezweni kwe-hydroxypropyl kunye namaqela e-methyl kwii-molecule ze-cellulose.

Imveliso ephumayo yipolymer enyibilikayo emanzini esetyenziswa kwizicelo ezahlukeneyo, kubandakanya amayeza, izithambiso, iimveliso zokutya, kunye nezongezo zokutya.I-Hypromellose ifumaneka kumabakala ahlukeneyo, kunye nobunzima beemolekyuli ezahlukeneyo kunye namaqondo okutshintshwa, kuxhomekeke kusetyenziso olucetywayo.

Ngokubanzi, i-hypromellose ithathwa njengento ekhuselekileyo kunye nokunyamezela kakuhle xa isetyenziswe njengoko kuyalelwe.Isetyenziswa ngokuqhelekileyo njenge-agent yokwambathisa, i-agent etyebisayo, kunye ne-stabilizer kwiimveliso ezininzi kwaye ixabiswa ngokukwazi kwayo ukuphucula ukuzinza kwemveliso, ukwandisa i-viscosity, kunye nokuphucula ukusebenza kwemveliso.
