Hypromellose, eo hape e tsejoang e le hydroxypropyl methylcellulose (HPMC), ke polymer ea maiketsetso e nkiloeng ho selulose.E entsoe ka ho fetola lik'hemik'hale selulose ea tlhaho e fumanoeng ho tloha lehong la lehong kapa likhoele tsa k'hothone ka mokhoa o tsejoang e le etherification.Ts'ebetsong ena, likhoele tsa cellulose li phekoloa ka motsoako oa propylene oxide le methyl chloride, e lebisang ho kenyelletsoeng ha lihlopha tsa hydroxypropyl le methyl ho limolek'hule tsa cellulose.

Sehlahisoa se hlahisoang ke polima e qhibilihang ka metsing e sebelisoang lits'ebetsong tse fapaneng, ho kenyeletsoa meriana, litlolo, lihlahisoa tsa lijo le li-supplement tsa lijo.Hypromellose e fumaneha ka limaraka tse fapaneng, ka litekanyo tse fapaneng tsa limolek'hule le likhato tsa sebaka, ho latela ts'ebeliso e reriloeng.

Ka kakaretso, hypromellose e nkoa e le motsoako o sireletsehileng le o mamelloang hantle ha o sebelisoa joalokaha o laetsoe.Hangata e sebelisoa e le ntho ea ho roala, e teteaneng le e tsitsitseng lihlahisoa tse ngata 'me e nkoa e le ea bohlokoa ka lebaka la bokhoni ba eona ba ho ntlafatsa botsitso ba sehlahisoa, ho eketsa viscosity le ho ntlafatsa ts'ebetso ea sehlahisoa.
