Abstract
Stable, concentrated aqueous suspensions of ortho-phenylphenol (OPP) which contribute minimal chemical oxygen demand 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 of OPP 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.
