I-PHARAMCEUTICAL EXOPIPIEIX
I-Hydroxypropyl Methylcellulose (HPMC) imhlophe noma i-Milky White White omhlophe, onamakha, ongenambitha, ongenakunambitha, ukuncipha kwesisindo, ukuncipha kwamanzi akwedlule amanzi ashisayo, kancane kancane ekuvuvukeni kwamanzi okushisayo, i-pottization, kanye nokwakha a Isixazululo se-dliscous colloidal, esiba yisixazululo lapho selenziwe, futhi siba yijeli lapho kufuthelwa. I-HPMC iyi-insoluble e-ethanol, chloroform ne-ether. Kuyancibilika ku-solvent exubile ye-methanol ne-methyl chloride. Kuyancibilika futhi ku-solvent ehlanganisiwe ye-acetone, i-methyl chloride ne-isopropanol nezinye izinto eziphilayo. Isixazululo sayo esinamanzi singabekezelela usawoti (isixazululo saso se-colloidal asibhujiswa ngosawoti), futhi i-PH yekhambi elingu-1% lingu-6-8. Ifomula ye-molecular ye-HPMC yi-C8H15O8- (C10h18o6) -C815o, kanye nesisindo esilinganiselwe se-molecular cishe ama-86,000.
I-HPMC ine-soubity yamanzi enhle kakhulu emanzini abandayo. Ingachithwa sisombululo esibonakalayo ngokuvusa okuncane emanzini abandayo. Ngokuphambene nalokho, ngokuyisisekelo kuncibilika emanzini ashisayo ngaphezulu kwama-60 ℃ futhi kungavuvukala kuphela. Kuyi-ether ye-celtuleose engeyona eye-ionic. Isixazululo saso asinakhokhiswa i-Ionic, ayisebenzisana nosawoti wensimbi noma amakhompiyutha we-ionic arganic, futhi awenzi nezinye izinto ezingavuthiwe ngesikhathi senqubo yokulungiselela; Inezakhiwo eziqinile zokulwa ne-anti-allergic, futhi ngokwanda kwesilinganiso sokufakwa esikhundleni sesakhiwo samangqamuzana, kuvela kakhulu ku-allergies futhi zizinze ngokwengeziwe; Futhi i-metabolically inert. Njenge-excipieint yezemithi, ayihlangene noma imunwe. Ngakho-ke, akuhlinzeki amakhalori emithini nokudla. Ikhalori ephansi, i-hast-free, futhi ayinawo usawoti mahhala. Izidakamizwa ze-Allergenic nokudla zinokusebenza okuhlukile; Kuyazinza kakhulu kuma-acids kanye ne-alkalis, kepha uma inani le-PH lidlula 2 ~ 11 futhi lithintwa amazinga okushisa aphezulu noma linesikhathi eside sokugcina, ukubonakala kwalo kuzokwehla; Isixazululo saso samanzi singanikeza umsebenzi wendawo, ekhombisa ukungezwani okulinganiselayo kanye nokungezwani kwezingcweti; Ine-emulsation ephumelelayo ohlelweni lwesigaba ezimbili, ingasetshenziswa njenge-stabilizer esebenzayo ne-colloid evikelayo; Isixazululo saso samanzi sinezakhiwo ezinhle kakhulu zefilimu, iyithebhulethi nephilisi elinezinto ezinhle zokuhlanganisa. I-coating yefilimu eyakhiwe yinayo inzuzo yokungabi nangenawo umbala nokuqina. Ukungeza i-glycerin nakho kungathuthukisa ipulasitiki yako.
Imikhiqizo ye-DickenCel® HPMC ingathuthuka yizakhiwo ezilandelayo ePharmaceutical Exepieint:
· Uma incibilika emanzini futhi iguqulwe nge-solvent, i-HPMC yenza ifilimu esobala ngamandla aphezulu ashubile.
· Khuthaza amandla okubopha.
· Hydrophilic matrix esetshenziswe kanye ne-HPMC hydrate ukudala ungqimba lwe-gel, elawula iphethini yokukhishwa kwezidakamizwa.
