Microbicidal Personal Care Compositions Comprising Metal Ions

摘要

Animate surface treatment compositions comprise (or in certain preferred embodiments may consist essentially of, or may consist of): a metal ion source material which releases copper ions and/or zinc ions into the treatment composition, in certain embodiments at least one alcohol which independently of other constituents present exhibits a microbicidal effect, in certain embodiments at least one quaternary ammonium compound which provides a microbicidal benefit, optionally but very preferably also at least one detersive surfactant, further optionally one or more further constituents which impart one or more advantageous technical or aesthetic benefits to the compositions, including one or more detersive surfactants, and water, wherein the compositions are at a pH such that the animate surface treatment compositions, exhibit a microbicidal or germicidal or antimicrobial effect on treated surfaces, which compositions are characterized in exhibiting a microbicidal benefit when tested against one or more challenge microorganisms according to one or more standardized test protocols.

1. An animate surface treatment composition which imparts an antimicrobial or microbicidal benefit to such treated surfaces which composition comprises
a metal ion source material selected from a copper ion source material which releases copper ions into the said treatment composition or a zinc ion source material which releases zinc ions into the said treatment composition; at least one quaternary ammonium compound which independently of other constituents present exhibits a microbicidal effect; at least one lower alkyl aliphatic monohydric alcohol which independently of other constituents present exhibits a microbicidal effect; water; and, optionally at least one further detersive surfactant, further optionally, one or more further constituents which impart one or more further technical or aesthetic benefits to the composition, wherein the treatment composition is characterized in exhibiting a microbicidal benefit when tested against one or more challenge microorganisms according to one or more of the following standardized test protocols: ASTM E1052 Standard Test Method for Efficacy of Antimicrobial Agents against Viruses in Suspension, or ASTM E1053 Standard Test Method to Assess Virucidal Activity of Chemicals Intended for Disinfection of Inanimate, Nonporous Environmental Surfaces, or European Standard Surface Test, EN1369, or AOAC Germicidal Spray Products as Disinfectant Test Method, AOAC Index, 17th Ed. (2000), or ASTM E2315-03(2008) Standard Guide for Assessment of Antimicrobial Activity Using a Time-Kill Procedure against one or more challenge microorganisms, especially preferably against gram positive bacteria, gram negative bacteria, preferably adenovirus and/or poliovirus type 1 (Sabin) (“PV1”).
