| titleOfInvention | Polyvinylpyrrolidone powder compositions |
| abstract | A polyvinylpyrrolidone powder composition including polyvinylpyrrolidone with a K value of not lower than 50 and not higher than 120, wherein a content of insoluble substances remaining on a membrane filter having a pore size of 1.2 μm when a 2 wt % aqueous solution of the composition is filtered with the filter is not higher than 70 ppm; a polyvinylpyrrolidone powder composition including polyvinylpyrrolidone with a K value of not lower than 50 and not higher than 120, wherein a K value lowering ratio to be observed when the composition is heated at 80° C. in air for 14 days is not higher than 12%; and a polyvinylpyrrolidone powder composition including polyvinylpyrrolidone with a K value of not lower than 50 and not higher than 120, wherein a content of insoluble substances remaining on a membrane filter having a pore size of 1.2 μm when a 2 wt % aqueous solution of the composition is filtered with the filter is not higher than 70 ppm, and a K value lowering ratio to be observed when the composition is heated at 80° C. in air for 14 days is not higher than 12%. |
