| POVIDONE-K90 | ( C6H9NO )n |
Povidone (polyvinylpyrrolidone, PVP) inoshandiswa muindasitiri yemishonga semotokari yepolymer yekugadzira yekuparadzira nekumisa zvinodhaka.Iine mashandisirwo akawanda, kusanganisira sebhainda remapiritsi nemakapisi, firimu raimbove remhinduro dzemaziso, kubatsira mukunakisa zvinwiwa uye mahwendefa anotsenga, uye seanonamira kune transdermal system.
Povidone ine molecular formula ye (C6H9NO) n uye inoratidzika sechena kune zvishoma kubva-chena poda.Povidone maumbirwo anoshandiswa zvakanyanya muindasitiri yemishonga nekuda kwekugona kwavo kunyungudika mumvura nemafuta zvinonyungudutsa.Iyo k nhamba inoreva huremu hwemamorekuru epovidone.Povidones ane K-akakwirira (kureva, k90) haawanzo kupihwa nejekiseni nekuda kwehuremu hwawo hwemamorekuru.Iyo yakakwira molecular uremu inodzivirira kubuda neitsvo uye inotungamira mukuungana mumuviri.Muenzaniso unonyanya kuzivikanwa wepovidone formulations ndeye povidone-iodine, yakakosha mushonga wekuuraya utachiona.
Kuyerera kwemahara, hupfu chena, kugadzikana kwakanaka, kusatsamwisa, kunyungudika mumvura uye ethnol, yakachengetekauye nyore kushandisa,.Inoshanda mukuuraya bacillus,mavhairasi & epiphytes.Inoenderana neakawanda pamusoro.
Iripo seyemahara inoyerera, red brown poda, isingatsamwise nekugadzikana kwakanaka, inonyungudika mumvura nedoro, isinganyungudika mu diethylethe uye chloroform.
