HPMC Hypromellose

Hydroxypropyl methylcellulose(HPMC), ikemikari inoshandiswa zvakasiyana-siyana ine fomula [C6H7O2(OH)3-mn(OCH3)m(OCH2CH(OH)CH3)n]x, apo m inomiririra dhigirii rekutsiva methoxy uye n inomiririra dhigirii rehydroxypropoxy. kutsiva. Iyo inotorwa kubva ku cellulose, yakasikwa polymer inowanikwa kubva kumadziro esero ezvirimwa. HPMC haina kunhuwa, haina kunaka, uye haina chepfu. Iyo ine akasiyana physicochemical zvimiro zvakaita solubility mumvura, thermal gelation properties, uye kugona kugadzira mafirimu, zvichiita kuti ishandiswe zvakanyanya mumaindasitiri akawanda.

Muindasitiri yemishonga, HPMC inoshandiswa zvakanyanya sechinhu chinobatsira-chinhu chinogadzirwa pamwe chete nechinhu chinoshanda chemushonga, nechinangwa chekudzikamisa kwenguva refu, kuunganidza maumbirwo akasimba ane zvine simba zvinoringana muzvikamu zvidiki (zvinowanzo kunzi seyekuzadza, diluent, kana mutakuri), kana kuwedzera kunyura kana kunyungudika. HPMC capsules ndeimwe nzira yegelatin capsules yevarimi uye inoshandiswa mukudzorwa-kuburitswa kwemaitiro, zvichibvumira kunonoka kuburitswa kwemushonga nekufamba kwenguva. HPMC mhinduro dzinogona zvakare kushanda seviscolyzers kuwedzera viscosity yeophthalmic solutions, kunatsiridza bioadherence, uye kurebesa nguva yekugara kwezvinodhaka pameso pemeso.

Muindasitiri yechikafu, HPMC inozivikanwa seyakachengeteka chikafu chekuwedzera (E464) uye inoshanda akawanda mabasa senge emulsifier, thickening agent, uye stabilizer. Inoshandiswa mukugadzira zvakasiyana-siyana zvekudya kuvandudza magadzirirwo, kuchengetedza hunyoro, uye kugadzira mafirimu anodyiwa. Iyo inopisa gelation pfuma yeHPMC inonyanya kukosha mumashandisirwo anoda gelling pane chaiyo tembiricha, senge mune yezvinomera uye vegan mabikirwo kwaanogona kutsiva gelatin. HPMC inobatsirawo kuhupenyu hwesherufu uye mhando yezvinhu zvakabikwa, sosi, uye dhizeti nekudzora kristalllization uye mwando.

Indasitiri yekuvaka inobatsira kubva kuHPMC mukugadzira zvinhu zvekuvaka. Zvishandiso zvaro zvinosanganisira kuita seanosungira uye kuchengetedza mvura mudhaka, plasters, uye machira, kuvandudza kushanda, kuderedza kushandiswa kwemvura, uye kuwedzera nguva yakavhurika - nguva iyo chinhu chinoramba chichishandiswa. HPMC inosimudzira zvimiro zvesimende-yakavakirwa maumbirwo, ichipa nani kunamatira, kupararira, uye kuramba kusagika.

Muindasitiri yezvizoro uye yekuchengeta munhu, HPMC inoshanda semugadziri wemufirimu, emulsifier, uye rheology modifier muzvigadzirwa zvakaita semafuta ekuzora, makirimu, uye gel ebvudzi. Kuenderana kwayo nemhando dzakasiyana dzeganda uye kugona kudzikamisa emulsions kunowedzera kuita kwechigadzirwa uye hupenyu hurefu. HPMC's hydration properties inoita kuti ive inodiwa inskin care products, inobatsira kuchengetedza hunyoro uye kupa kunzwa kwakatsetseka. Muchidimbu, kuita kwakasiyana-siyana kweHPMC kunobata mishonga, chikafu, kuvaka, uye zvizorwa, zvichiratidza kukosha kwayo sechinhu chinoshanda mune zvakasiyana siyana.
