HPMC Hypromellose

Hydroxypropyl methylcellulose(HPMC), ke motsoako oa lik'hemik'hale o sebetsang ka mefuta-futa o nang le foromo [C6H7O2(OH)3-mn(OCH3)m(OCH2CH(OH)CH3)n]x, moo m e emelang tekanyo ea methoxy substitution' me n e emela tekanyo ea hydroxypropoxy. ho nkela sebaka. E tsoa ho cellulose, polymer ea tlhaho e fumanoang marakong a lisele tsa limela. HPMC ha e na monko, ha e latsoehe, ebile ha e chefo. E na le lisebelisoa tse fapaneng tsa physicochemical joalo ka ho qhibiliha ka metsing, thepa ea gelation ea mocheso, le bokhoni ba ho etsa lifilimi, ho etsa hore e sebelisoe haholo liindastering tse ngata.

Indastering ea meriana, HPMC e sebelisoa haholo e le mothusi-e leng ntho e entsoeng hammoho le motsoako o sebetsang oa meriana, ka morero oa ho tsitsisa nako e telele, ho bokella metsoako e tiileng e nang le metsoako e matla e sebetsang ka tekanyo e nyenyane (kahoo hangata e bitsoa joalo ka setlatsi, se hlapollang, kapa sejari), kapa ho matlafatsa ho monya kapa ho qhibiliha. Li-capsules tsa HPMC ke mokhoa o mong oa li-gelatin capsules bakeng sa batho ba jang meroho 'me li sebelisoa ka mokhoa o laoloang-ho lokolloa, ho lumella ho lokolloa butle ha moriana ha nako e ntse e ea. Litharollo tsa HPMC li ka boela tsa sebetsa e le li-viscolyzers ho eketsa viscosity ea tharollo ea mahlo, ho ntlafatsa bioadherence, le ho lelefatsa nako ea ho lula ha lithethefatsi sebakeng sa mahlo.

Indastering ea lijo, HPMC e amoheloa e le sehokelo sa lijo se bolokehileng (E464) mme e sebeletsa mesebetsi e mengata joalo ka emulsifier, motenya, le stabilizer. E sebelisoa ho hlahisa mefuta e fapaneng ea lijo ho ntlafatsa sebopeho, ho boloka mongobo le ho etsa lifilimi tse jeoang. Thepa e futhumatsang ea HPMC e bohlokoa haholo lits'ebetsong tse hlokang ho jelloa ka mocheso o itseng, joalo ka lijong tsa meroho le vegan moo e ka nkang sebaka sa gelatin. HPMC e boetse e kenya letsoho bophelong ba lishelefo le boleng ba thepa e halikiloeng, li-sauces, le li-dessert ka ho laola kristale le mongobo.

Indasteri ea kaho e rua molemo ho HPMC ha ho etsoa thepa ea moaho. Ts'ebeliso ea eona e kenyelletsa ho sebetsa joalo ka setlamo le ho boloka metsi ka har'a seretse, lipolasetere le lirafshoa, ho ntlafatsa ts'ebetso, ho fokotsa tšebeliso ea metsi, le ho eketsa nako e bulehileng - nako eo thepa e lulang e sebelisoa. HPMC e ntlafatsa thepa ea liforomo tse thehiloeng ho samente, e fana ka ho khomarela hantle, ho ata, le ho hanyetsa ho sagging.

Ka indasteri ea litlolo le tlhokomelo ea botho, HPMC e sebetsa e le moemeli oa ho etsa lifilimi, emulsifier, le rheology modifier lihlahisoa tse kang lotions, litlolo le li-gels tsa moriri. Ho lumellana ha eona le mefuta e fapaneng ea letlalo le bokhoni ba ho tsitsisa li-emulsions ho ntlafatsa ts'ebetso ea sehlahisoa le bophelo bo bolelele. Thepa ea HPMC's hydration e etsa hore e be motsoako o lakatsehang oa lihlahisoa tsa tlhokomelo ea letlalo, e thusang ho boloka mongobo le ho fana ka maikutlo a boreleli. Ka bokhuts'oane, ho feto-fetoha ha maemo ha HPMC ho kenyelletsa meriana, lijo, kaho le litlolo, ho totobatsa bohlokoa ba eona e le motsoako o sebetsang ka bongata lits'ebetsong tse fapaneng.
