I-Povidone-K90 / PVP-K90
Isingeniso:
| Isekiso | Amangqamuzana |
| IPovidone-K90 | (C6h9no) n |
IPovidone (Polyvinylpyrolone, i-PVP) isetshenziswa embonini yezemithi njengemoto ye-polymer yokwenziwa yokusabalalisa nokumisa izidakamizwa. Inokusetshenziswa okuningi, kufaka phakathi njengesixhumanisi samathebulethi nama-capsule, ifilimu yangaphambili ye-ophthalmic solutions, ukusiza ekutholeni uketshezi namathebulethi ama-cntidermal.
IPovidone inefomula ye-molecular (C6h9no) n futhi ivela njengomhlophe ku-powder emhlophe kancane. Izakhi zePvidone zisetshenziswa kabanzi embonini yezemithi ngenxa yekhono labo lokuncibilikisa kuwo womabili ama-solvents amanzi. Inombolo k isho isisindo se-molecular se-povidone. Ama-Popidones anama-K-amanani aphezulu (ie, k90) awavamiswa kaningi ngomjovo ngenxa yezinsimbi zawo eziphakeme. Izinsimbi eziphakeme zamangqamuzana zivimbela ukukhishwa yizinso futhi kuholele ekuqongeleleni emzimbeni. Isibonelo esaziwa kakhulu sokwakhiwa kwePovidone i-Povidone-Iodine, i-magciwane ebalulekile.
Ukugeleza kwamahhala, i-powder emhlophe, ukuzinza okuhle, okungacasuli, okuncibilikayo emanzini kanye ne-ethnol, kuphephileFuthi kulula ukuyisebenzisa, .Ectiofting ekubulaleni i-bacillus, amagciwane kanye nama-epiphytes) ahambisane kakhulu nendawo eningi.
Ikhona njengokugeleza kwamahhala, i-powder emnyama, engacasuli ngokuqina okuhle, chaza ngamanzi notshwala, insoluble eDiethylethe naseChloroform ne-Chloroform.

Ukubeka
Iminyaka emibili uma igcinwe ngaphansi kwezimo ezipholile nezomile nesitsha esivaliwe kahle
I-polyvinylpyrrolidone imvamisa ngesimo se-powder noma isixazululo ikhona. I-PvP kuma-cosmetics mousse, ukuqhuma, nezinwele, upende, i-inki yokuphrinta, izindwangu, ukuphrinta kanye nokudaya, amashubhu wezithombe zemibala angasetshenziswa njengama-ejenti ahlanganisiwe, ama-ejenti asabalalisa, ama-ejenti, ama-linders. Kwezokwelapha kusetshenziswa kakhulu amabhande amaphilisi, ama-granules nokunye.
