Povidone
Povidone he homopolymer o 1-vinyl-2-pyrrolidone (Polyvinylpyrrolidone), he wairewa noa ki te wai, i te waihono (96%), i roto i te methanol, me etahi atu whakarewa koiora, ka rewa noa i roto i te acetone. He polymer hygroscopic tenei, he mea tuku ki te paura ma, te kirikiri ranei, he maama ranei, mai i te iti ki te teitei o te pokapoka. ki te taumaha o te ngota ngota, e whakaatuhia ana e te Uara K, me te tino hygroscopisty, te hanga kiriata, te piripiri, te pumau o te matū me te wairua noho taikaha.
