<p>A method of increasing the antimicrobial activity of an aqueous, antimicrobial liquid cleaning formulation. The method includes the step of blending a polymeric deposition aid composed of a mixture of liquid, hydroxyl-terminated urethane polymers in polyethylene glycol together with a phenol derivative antimicrobial agent and a surfactant such that the liquid cleaning formulation has at least 10 percent greater antimicrobial activity than the same formulation without the polymeric deposition aid.</p> |
