US 2010/0136077 A1 · BIOCIDIC HOUSEHOLD CLEANSING MATERIALS

Abstract

The present invention discloses household cleaning materials comprising at least one insoluble proton sink or source (PSS) and to method for utilizing the PSS as a biocidic agent. The household cleaning materials are provided useful for killing living target cells (LTCs) or otherwise inhibiting LTCs growth, disrupting vital intracellular processes and/or intercellular interactions of the LTC upon contact. The household cleaning materials consisting of at least one PSS, comprises, inter alia, (i) proton source or sink providing a buffering capacity; and (ii) means providing proton conductivity and/or electrical potential. The PSS is effectively disrupting the pH homeostasis and/or electrical balance within the confined volume of said LTC and/or disrupting vital intercellular interactions of said LTCs while efficiently preserving the pH of said LTCs' environment.
