Abstract
Synergistic mixtures of haloamines and non-oxidizing biocides and their use to control the growth of microorganisms in aqueous systems is provided. The methods entail adding an effective amount of at least one haloamine and at least one non-oxidizing biocide to an aqueous system thereby producing a biocidal synergistic effect.
Claims25
A method for controlling the growth of microorganisms in an aqueous system comprising adding an effective amount of haloamine and a non-oxidizing biocide to said aqueous system, wherein said effective amount of haloamine and non-oxidizing biocide provides a synergy index of less than 1.
A synergistic mixture comprising a haloamine and a non-oxidizing biocide in an aqueous system wherein the weight ratio of haloamine to the non-oxidizing biocide is from about 1,000:1 to about 1:50, the amount of the haloamine ranges from about 0.1 to about 50 parts per million (ppm) by weight on an active level basis, and the amount of the non-oxidizing biocide ranges from about 0.001 to about 40 ppm by weight on an active level basis.
