Biocidal compositions and use thereof containing a synergistic mixture of 2-bromo-2-nitropropane-1,3-diol and tri-n-butyl tetradecyl phosphonium chloride

摘要

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 2-bromo-2-nitropropane-1,3-diol (BNPD) and "Belclene 350." The active biocidal component of the "Belclene 350" product is tri n-butyl tetradecyl phosphonium chloride. The method comprises administering between about 0.1 to about 200 parts of this composition (i.e., BNPD and "Belclene 350" product) (based on one million parts of the desired aqueous system) to the particular water containing system for which treatment is desired.
