Povidone-K90 / PVP-K90 Yogulitsa Kwambiri
Chiyambi:
| INCI | Mamolekyulu |
| POVIDONE-K90 | ( C6H9NO ) n |
Povidone (polyvinylpyrrolidone, PVP) imagwiritsidwa ntchito mumakampani opanga mankhwala ngati njira yopangira polima yofalitsira ndi kuyimitsa mankhwala. Imagwiritsidwa ntchito m'njira zambiri, kuphatikizapo ngati chomangira mapiritsi ndi makapisozi, filimu yopangira mayankho a maso, kuthandiza pakukometsera zakumwa ndi mapiritsi otafuna, komanso ngati chomatira cha machitidwe a transdermal.
Povidone ili ndi mawonekedwe a molekyulu a (C6H9NO)n ndipo imawoneka ngati ufa woyera mpaka wosakhala woyera pang'ono. Mafomula a Povidone amagwiritsidwa ntchito kwambiri mumakampani opanga mankhwala chifukwa amatha kusungunuka m'madzi ndi mafuta. Nambala ya k imatanthauza kulemera kwapakati kwa molekyulu ya povidone. Ma Povidone okhala ndi ma K-values okwera (monga, k90) nthawi zambiri saperekedwa ndi jakisoni chifukwa cha kulemera kwawo kwakukulu kwa molekyulu. Kulemera kwakukulu kwa molekyulu kumaletsa kutulutsa kwa impso ndikutsogolera kusonkhanitsa m'thupi. Chitsanzo chodziwika bwino cha mafomula a povidone ndi povidone-iodine, mankhwala ophera tizilombo toyambitsa matenda ofunikira.
Yoyenda bwino, ufa woyera, yokhazikika bwino, yosakwiyitsa, yosungunuka m'madzi ndi ethnol, yotetezekandipo ndi yosavuta kugwiritsa ntchito,. Yothandiza kupha tizilombo toyambitsa matenda, mavairasi ndi epiphytes. Imagwirizana ndi malo ambiri.
Imapezeka ngati ufa wosalala, wofiira bulauni, wosakwiyitsa komanso wokhazikika bwino, umasungunuka m'madzi ndi mowa, susungunuka mu diethylethe ndi chloroform.

Zaka ziwiri ngati zasungidwa pamalo ozizira komanso ouma komanso chidebe chotsekedwa bwino
Polyvinylpyrrolidone nthawi zambiri imakhala ngati ufa kapena yankho. PVP mu zodzoladzola mousse, eruption, ndi tsitsi, utoto, inki yosindikizira, nsalu, kusindikiza ndi kupaka utoto, machubu azithunzi zamitundu angagwiritsidwe ntchito ngati zophimba pamwamba, zotulutsira, zokhuthala, zomangira. Mu mankhwala ndi zomangira zomwe zimagwiritsidwa ntchito kwambiri pa mapiritsi, granules ndi zina zotero.
