Abstract
Stable, concentrated aqueous suspensions of 2,2-dibromo-3-nitrilopropionamide which contribute minimal chemical oxygen demand to systems treated therewith and methods of preparing and using said suspensions in biocidal applications have been discovered. The formulations comprise from about 3 to about 70 weight percent 2,2-dibromo-3-nitrilopropionamide suspended in about 30 to about 97 weight percent water in the presence of a suspending amount of a thixotrope that exhibits Ellis-Plastic behavior, such as xantham gum and locust bean gum, at a pH of from about 1 to about 4.
