I-Povidone-K90 / PVP-K90 Amapharamitha

Isingeniso:

INCI Amangqamuzana
I-POVIDONE-K90 ( C6H9NO )n

I-Povidone (i-polyvinylpyrrolidone, i-PVP) isetshenziswa embonini yezemithi njengemoto ye-polymer yokwenziwa yokuhlakaza nokumisa izidakamizwa.Inokusetshenziswa okuningi, okuhlanganisa njengesibophezelo samaphilisi namaphilisi, ifilimu yangaphambili yezixazululo ze-ophthalmic, ukusiza ekunambiseni uketshezi namaphilisi ahlafunwayo, futhi njengento enamathelayo yezinhlelo ze-transdermal.

I-Povidone inefomula yamangqamuzana engu-(C6H9NO)n futhi ibonakala njengempushana emhlophe ukuya kokumhlophe kancane.Amafomu e-povidone asetshenziswa kabanzi embonini yezemithi ngenxa yekhono lawo lokuncibilika kokubili emanzini namafutha e-solvents.Inombolo engu-k ibhekisela esisindweni se-molecule ye-povidone.Ama-povidone anamanani aphezulu we-K (okungukuthi, i-k90) awavamisile ukunikelwa ngomjovo ngenxa yesisindo sawo samangqamuzana aphezulu.Izisindo eziphakeme zamangqamuzana zivimbela ukukhishwa kwezinso futhi ziholela ekuqongeleleni emzimbeni.Isibonelo esaziwa kakhulu sokwakheka kwe-povidone yi-povidone-iodine, isibulala-magciwane esibalulekile.

Ukugeleza kwamahhala,impushana emhlophe,ukuzinza okuhle,okungacunuli,kuncibilika emanzini kanye ne-ethnol,iphephilefuthi kulula ukuyisebenzisa,.Isebenza ngempumelelo ekubulaleni i-bacillus,amagciwane nama-epiphyte.Ihambisana nezindawo eziningi.

Ikhona njengokugeleza kwamahhala, impushana ensundu ngokubomvu, engacasuli ngokuzinza okuhle, incibilika emanzini nasetshwaleni, engancibiliki ku-diethylethe ne-chloroform.

Isicelo se-Povidone-K90 / PVP-K90

I-Polyvinylpyrrolidone ngokuvamile isesimweni sempushana noma isixazululo ikhona.I-PVP ku-cosmetics mousse, ukuqhuma, nezinwele, upende, inki yokunyathelisa, indwangu, ukuphrinta nokudaya, amashubhu esithombe sombala angasetshenziswa njengama-ejenti okugqoka angaphezulu, ama-agent ahlakazayo, ama-thickeners, ama-binder.Emithini kusetshenziswa kakhulu izibophezelo zamaphilisi, ama-granules nokunye.
