  • Method for cleaning hard surfaces using an aqueous solution of quaternary ammonium compound, combination of nonionic surfactant and glycol ether solvent
    Patent number: 5522942
    Abstract: A synergistic cleaning composition has been discovered comprising an aqueous solution a quaternary ammonium compound component; a nonionic surfactant component; and a glycol ether solvent. Surprisingly, the combination of the quaternary ammonium compound component, the nonionic surfactant component, and glycol ether solvent provides a synergistic effect where the cleaning composition functions with a low level of quaternary ammonium compound component while still maintaining at least one of the following desirable properties, as follows: an acceptable cleaning efficacy; a low level irritation or toxicity profile; and/or a broad spectrum antimicrobial activity.
    Type: Grant
    Filed: July 7, 1995
    Date of Patent: June 4, 1996
    Assignee: Reckitt & Colman Inc.
    Inventors: Beth T. G. Graubart, Allan L. Streit, Ernest J. Sachs, Carol A. Beronio
