Povidone-K90 / PVP-K90 ku bucuruzi bwinshi
Intangiriro:
| INCI | Molekulike |
| POVIDONE-K90 | (C6H9NO) n |
Povidone (polyvinylpyrrolidone, PVP) ikoreshwa mu nganda zikora imiti nk'ikinyabutabire cya polymer cy’ubukorikori mu gukwirakwiza no guhagarika imiti. Ifite akamaro kenshi, harimo nk'ikintu gifunga ibinini na kapsule, icyuma gikoreshwa mu gupima amaso, gufasha mu gusiga uburyohe bw'ibinyobwa n'ibinini byo guhekenya, ndetse no nk'igikoresho cyo gufatanya uruhu.
Povidone ifite formula ya molekile ya (C6H9NO)n kandi igaragara nk'ifu y'umweru kugeza ku ifu y'umweru. Imiterere ya Povidone ikoreshwa cyane mu nganda zikora imiti bitewe n'ubushobozi bwayo bwo gushonga mu byuma biyungurura amazi n'amavuta. Umubare wa k yerekeza ku buremere bw'impuzandengo ya povidone. Povidone zifite agaciro ka K-gaciro kari hejuru (ni ukuvuga k90) ntizikunze gutangwa hakoreshejwe urushinge bitewe n'uburemere bwazo bwinshi bwa molekile. Uburemere bwinshi bwa molekile buza impyiko gusohora kandi bigatera kwirundanya mu mubiri. Urugero ruzwi cyane rwa povidone ni povidone-iyode, umuti w'ingenzi wo kwica udukoko.
Itemba neza, ifu yera, ihamye neza, ntitera umujinya, ishongesha mu mazi no mu mazi, kandi itekanye kurushahokandi byoroshye gukoresha,. Bifasha mu kwica bacillus, virusi na epiphytes. Bijyanye n'ubuso bwinshi.
Ibaho nk'ifu y'umukara utukura, idatera umujinya kandi ihamye, ishongesha mu mazi na alukolo, ntishongesha muri diethylethe na chloroform.

Ububiko
Imyaka ibiri iyo bibitswe ahantu hakonje kandi humutse kandi mu gikoresho gifunze neza
Ubusanzwe haba mu buryo bw'ifu cyangwa umuti. PVP mu bijyanye n'ubwiza, mousse, eruption, n'umusatsi, irangi, wino yo gucapa, imyenda, icapiro n'irangi, imiyoboro y'amabara ishobora gukoreshwa nk'ibintu bisiga ku buso, ibintu bigabanya ubushyuhe, ibintu binini, ibifunga. Mu buvuzi, hari ibintu bifunga bikoreshwa cyane ku binini, granules n'ibindi.
