Abstract
Generation of foam when spraying biofilm-detection compositions onto a surface may entrain air and create bubbles, which lead to false positives. Aqueous biofilm-detecting compositions containing low-foaming surfactants, radical scavenger, solvent, thickener, hydrogen peroxide, chelating and coupling agent may be sprayed onto a surface to test for the presence of biofilm without generating excess bubbles or foam.
