Abstract
Abstract An aqueous, antimicrobial liquid cleaning formulation including: 1) a polymeric deposition aid composed of a mixture of liquid, hydroxyl-terminated urethane polymers in polyethylene glycol; 2) a phenol derivative antimicrobial agent; and 3) a surfactant system comprising predominantly nonionic surfactants, amphoteric surfactants or combinations thereof such that the liquid cleaning formulation provides at least about 10 percent greater antimicrobial activity than the same formulation without the polymeric deposition aid.
