I-HPMC HYPROMELLOSE

Hydroxypropyl methylcellulose(HPMC), iyingxenye yamakhemikhali ehlukahlukene ngeFomula [C6H7O2 (oh) 3-MN indawo. Kuthathwe ku-cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. I-HPMC ayinaphutha, ayinambitha, futhi ayinobuthi. Inezakhiwo ezahlukahlukene ze-physicochemical ezinjenge-solubity emanzini, izakhiwo ezishisayo ze-gelation, kanye nekhono lokukha amafilimu, okwenza lisetshenziswe kabanzi kuzo zonke izimboni eziningi.

Embonini yezemithi, i-HPMC isetshenziswa kabanzi njengento ethokozisayo - eyenziwe ngento eyenziwe eceleni kwesithako somuthi, ngenhloso yokuzinza okunesikhathi eside, inhloso yokuzinza okunamandla okuqukethe izithako ezinamandla ezinamandla ngamanani amancane (ngaleyo ndlela kuvame ukubizwa ngokuthi Njengomsizi, ongcolile noma ophethe), noma ukuthuthukisa ukumuncwa noma nge-solubility. Ama-HPMC capsule ahlukile kuma-gelatin caplule for imifino futhi asetshenziswa ekwenziweni okulawulwa okulawulwayo, okuvumela ukukhishwa okuhamba kancane kwesidakamizwa ngokuhamba kwesikhathi. Izixazululo ze-HPMC nazo zingasebenza njenge-viscolyzers ukukhulisa i-viscosity yezixazululo ze-ophthalmic, thuthukisa i-bioahere, futhi yandise isikhathi sokuhlala sezidakamizwa endaweni ye-ocular.

Embonini yokudla, i-HPMC yamukelwa njengesengezo sokudla esiphephile (i-E464) futhi isebenza imisebenzi eminingi efana ne-emulsifier, i-ejenti yokuqina kanye ne-stabilizer. Kuqashwa ekukhiqizweni kokudla okuhlukahlukene ukuthuthukisa ukuthungwa, ukugcina umswakama, kanye namafilimu adliwayo. I-Thermal Gelation Property ye-HPMC ibaluleke kakhulu kwizicelo ezidinga ukuceba emazingeni okushisa athile, njengokupheka kwemifino kanye ne-vegan lapho kungathatha khona i-gelatin. I-HPMC nayo inikela empilweni yeshelufu nekhwalithi yezimpahla ezibhakiwe, amasoso, kanye nama-dessert ngokulawula i-crystallization kanye nomswakama.

Imboni yezokwakha izuza ku-HPMC ekwenziweni kwezinto zokwakha. Izicelo zayo zifaka phakathi i-ejenti ne-ejenti yokugcina amanzi ezinhlotsheni, ama-porsasters, kanye nokwenza umsebenzi, ukunciphisa ukusetshenziswa kwamanzi, nokunwebeka isikhathi esivulekile - isikhathi lapho kuqhubeka khona into ethile. I-HPMC ithuthukisa izakhiwo zokwakheka esekwe ku-monce, ukuhlinzeka ngokunamathelisa okungcono, ukusakazeka kanye nokumelana nokuhlanza.

Ezimonyo kanye nemboni yokunakekelwa komuntu siqu, i-HPMC isebenza njenge-ejenti eyakha amafilimu, i-emulsifier, kanye nokushintsha kwe-Rheology emikhiqizweni efana nama-lotions, okhilimu kanye nezinwele. Ukuhambisana kwalo ngezinhlobo ezahlukahlukene zesikhumba nekhono lokuqinisa ama-emulsions akhulisa ukusebenza komkhiqizo nokuphila isikhathi eside. Izakhiwo ze-hpmc ze-hydration zikwenza kube yimikhiqizo yokunakekelwa kwe-ingn inskin, esiza ukugcina umswakama futhi inikeze umuzwa obuhle. Ngamafuphi, ukuguquguquka okuhlukahlukene kwe-HPMC spans Pharmaceuticals, ukudla, ukwakha, kanye nezimonyo, kugqamisa ukubaluleka kwayo njengesithako esisebenzayo kuzicelo ezahlukahlukene.
