Biocidal compositions and use thereof containing a synergistic mixture of tetraalkyl phosphonium halide and n-alkyl dimethylbenzyl ammonium chloride

摘要

A bactericidal composition and method for inhibiting and controlling the growth of the capsulated, facultative bacterium, Klebsiella pneumoniae, are disclosed. The composition comprises an amount, effective for the intended purpose, of n-alkyl dimethyl benzyl ammonium chloride and tetraalkyl phosphonium halide. The method comprises administering between about 0.1 to about 200 parts of this combined treatment (based on one million parts of the desired aqueous system) to the particular water containing system for which treatment is desired.
