Iyini i-HPMC k15?

I-HPMC K15 iyibanga le-hydroxypropyl methylcellulose (HPMC) ye-cellulose ether, enobubanzi be-viscosity 12.0-18.0, okuwuhlobo lwempahla ye-polymeric encibilika emanzini.Kuyimpushana emhlophe, engenaphunga, enganambitheki esetshenziswa njenge-ejenti ejiyayo, i-stabilizer, kanye ne-emulsifier emikhiqizweni eyahlukene.I-HPMC K15 iyi-ether engeyona ionic cellulose, okusho ukuthi ayiqukethe noma yimaphi amaqembu e-ionic ngakho-ke ayisebenzi.Isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi ukudla, imithi, izimonyo, nemikhiqizo yezimboni.

I-HPMC K15 iyizinga eliphezulu lesisindo samangqamuzana e-HPMC, okusho ukuthi yakhiwe ngamaketanga amade ama-molecule.Lokhu kuyenza ibe i-agent ekahle yokuqina, njengoba ikwazi ukwenza isakhiwo esifana nejeli lapho ixutshwe namanzi.Lesi sakhiwo esifana nejeli sandisa i-viscosity yesisombululo, okwenza kube i-agent ephumelelayo yokuqina.I-HPMC K15 futhi iyi-emulsifier enhle, okusho ukuthi ingasiza ukuzinzisa ingxube kawoyela namanzi, ivimbele ukuthi ihlukane.Lokhu kuyenza ibe wusizo emikhiqizweni eyahlukene, njengamakhilimu, ama-lotions, namafutha okugcoba.

I-HPMC K15 iyimpahla ephephile nengenabo ubuthi, iyenza ifanelekele ukusetshenziswa ekudleni nasemikhiqizweni yezemithi.Igunyazwe futhi yi-FDA ukuthi isetshenziswe ekudleni nasezimonyoni, futhi ithathwa njengephephile ukuthi isetshenziswe abantu.I-HPMC K15 futhi iyimpahla ehambisana nemvelo, njengoba ibola futhi ayinabo ubuthi.

I-HPMC K15 iwumsebenzi oguquguqukayo ongasetshenziswa ezinhlelweni ezahlukahlukene.Kuyi-ejenti yokuqina esebenzayo, i-emulsifier, kanye ne-stabilizer, okuyenza ibe wusizo emikhiqizweni eminingi.Iphephile futhi, ayinabo ubuthi, futhi ayihambisani nemvelo, okuyenza ibe yinhle ukukhetha ukuthi isetshenziswe ekudleni, emithini yemithi nasezimonyo.
