<P>PROBLEM TO BE SOLVED: To provide a method and a composition for maintaining the microbicidal activity of a histidine-silver complex even in a chlorine ion-containing liquid. <P>SOLUTION: The microbicidal activity of the histidine-silver complex in a chlorine ion-containing liquid is maintained by adding a water-soluble nitrogen-containing polymer, such as one typically represented by a polyethyleneimine, to obtain an effect preventing the reaction of the histidine silver complex with the chlorine ion. In addition, a liquid antimicrobial agent composition is obtained by mixing (a) silver oxide, (b) L-histidine, (c) a water-soluble nitrogen-containing polymer and (d) a solvent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
