The antimicrobial acitivy of surface active substances applied in mixtures of different ionic species was investigated ; growth-inhibiting concentration, prolongation of lag time and decrease in viable count were measured employing bacteria, yeasts and molds as test organisms.Cationics were not always antagonized by anionics : for example, the antimicrobial activity of DPC was scarcely antagonized by the equal amount of anionics. On the other hand, typical antagonism was observed with Softex (or Osvan) when added in congunction with anionics, although antimicrobial activity was still remarlable even at the highest antagonism attainable.The degree of antagonism of this kind was dependent not only upon the chemical structure of drugs, but also upon test organis, pH of media and the mixing ratio of drugs (cf. Table 1〜8,Fig. 1〜2,page 297〜303).
