| POVIDONE-K90 | ( C6H9NO ) n |
Povidone (polyvinylpyrrolidone, PVP) amagwiritsidwa ntchito m'makampani opanga mankhwala ngati galimoto yopangira polima yobalalitsa ndi kuyimitsa mankhwala.Imakhala ndi ntchito zingapo, kuphatikiza ngati chomangira mapiritsi ndi makapisozi, filimu yomwe kale inali yopangira mankhwala a maso, kuthandiza pakukometsera zamadzimadzi ndi mapiritsi omwe amatha kutafuna, komanso zomatira pamakina a transdermal.
Povidone ili ndi mamolekyu a (C6H9NO)n ndipo imawoneka ngati yoyera mpaka yoyera pang'ono.Mapangidwe a Povidone amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala chifukwa amatha kusungunuka m'madzi ndi mafuta osungunulira.Nambala ya k imatanthawuza kulemera kwa molekyulu ya povidone.Ma povidone okhala ndi ma K-values apamwamba (ie, k90) nthawi zambiri samaperekedwa ndi jekeseni chifukwa cha kulemera kwawo kwa mamolekyu apamwamba.Kulemera kwa mamolekyu kumalepheretsa kutuluka kwa impso ndi kumapangitsa kuti thupi likhale lochuluka.Chitsanzo chodziwika bwino cha mankhwala a povidone ndi povidone-iodine, mankhwala ophera tizilombo toyambitsa matenda.
Ufa wopanda pake, ufa woyera, kukhazikika kwabwino, osakwiyitsa, kusungunuka m'madzi ndi ethnol, otetezekakomanso yosavuta kugwiritsa ntchito,.Yothandiza pakupha tizilombo toyambitsa matenda, ma virus & epiphytes.Yogwirizana ndi zambiri pamtunda.
Imakhalapo ngati ufa waufulu, wonyezimira wofiirira, wosakwiyitsa ndi kukhazikika bwino, kusungunuka m'madzi ndi mowa, osasungunuka mu diethylethe ndi chloroform.

Kusungirako
Zaka ziwiri ngati kusungidwa ozizira ndi youma zinthu ndi bwino chatsekedwa chidebe
Polyvinylpyrrolidone nthawi zambiri amakhala ngati ufa kapena yankho.PVP mu zodzoladzola mousse, kuphulika, ndi tsitsi, utoto, inki yosindikizira, nsalu, kusindikiza ndi utoto, machubu azithunzi amtundu angagwiritsidwe ntchito ngati othandizira pamwamba, obalalitsa, thickeners, binders.Mu mankhwala ambiri ntchito binders kwa mapiritsi, granules ndi zina zotero.
