Hydroxypropylmethylcellulose (HPMC) ke polymer e sebelisoang haholo liindastering tse fapaneng. Ke ether e se nang ionic cellulose, e qhibilihang ka metsing, e se nang chefo le e sa khathatseng. HPMC e atisa ho sebelisoa e le sekontiri, se tlamang le se emulsifier lijong tse ngata, meriana le lihlahisoa tsa tlhokomelo ea botho.
E 'ngoe ea thepa ea bohlokoa ea HPMC ke boima ba eona ba molek'hule, e amang viscosity ea eona. Viscosity ke tekanyo ea hore mokelikeli o hana ho phalla. Ha viscosity e phahame, mokelikeli o motenya. Boima ba molek'hule ke tekanyo ea boholo ba molek'hule, e amanang ka ho toba le viscosity ea HPMC.
HPMC e fumaneha ka limaraka tse fapaneng ho latela boima ba eona ba molek'hule. The viscosity ea HPMC eketseha ka boima ba molek'hule. Viscosity ea HPMC e boetse e susumetsoa ke degree of substitution (DS), e leng palo ea lihlopha tsa hydroxypropyl le methyl tse khomaretsoeng mokokotlong oa cellulose. Ha DS e phahame, boima ba molek'hule le viscosity ea HPMC e phahame.
Viscosity ea HPMC e boetse e angoa ke mahloriso a polymer tharollong. Maemong a tlase, liketane tsa polymer lia qhalakanngoa mme viscosity ea tharollo e tlase. Ha mahloriso a ntse a eketseha, liketane tsa polymer li qala ho kopana le ho ts'oarana, e leng se bakang keketseho ea viscosity. Khatiso eo liketane tsa polymer li qalang ho kopana li bitsoa "overlap concentration".
Boima ba limolek'hule le viscosity ea HPMC ke litekanyetso tsa bohlokoa mefuteng e mengata ea lihlahisoa. Indastering ea lijo, HPMC e sebelisoa e le setepi sa li-sauces, liaparo le lintho tse halikiloeng. Boima bo nepahetseng ba limolek'hule le viscosity ea HPMC e netefatsa sebopeho se lakatsehang le molomo oa sehlahisoa sa ho qetela.
Indastering ea meriana, HPMC e sebelisoa e le setlamo sa matlapa le li-capsules. Boima ba limolek'hule le viscosity ea HPMC li khetholla matla a letlapa le bokhoni ba lona ba ho qhibiliha ka har'a pampiri ea mala.
Indastering ea tlhokomelo ea motho ka mong, HPMC e sebelisoa joalo ka ntho e tenya le emulsifier ho li-shampoo, litlolo le litlolo. Boima bo loketseng ba limolek'hule le viscosity ea HPMC e netefatsa ho lumellana ho loketseng le botsitso ba sehlahisoa.
Ho akaretsa, boima ba limolek'hule le viscosity ea HPMC ke likarolo tsa bohlokoa tse amang ts'ebetso ea eona liindastering tse fapaneng. Ho utloisisa kamano lipakeng tsa liparamente tsena ho bohlokoa ho theha lihlahisoa tse fihlelang litlhaloso tse lakatsehang. HPMC ke polymer e feto-fetohang le ea bohlokoa e thusang ho ntlafatsa boleng le ts'ebetso ea lihlahisoa tse ngata.
