Abstract

The present invention relates to quaternary ammonium disinfecting cleaning compositions comprising a quaternary ammonium compound, an alkyl a polyglycoside with a CMC greater than 1000 ppm and a chelant. Beneficially, the compositions provide residual sanitizing efficacy without diminished performance and without scale formation when diluted with hard water. The compositions are suitable for inactivating and/or reducing infectious agents, particularly Norovirus, Adenovirus, and Polyomavirus.

First claim

What is claimed is:

1. A sanitizing composition comprising:
a) from about 0.7 wt. % to about 40.0 wt. % of a unimer biocidal quaternary ammonium compound;
b) from about 1.3 wt. % to about 80.0 wt. % of an alkyl polyglycoside surfactant;
c) from about 1.5 wt. % to about 90.0 wt. % of a C12 or higher amine oxide; and
d) from about 0.1 wt. % to about 4.0 wt. % of a chelant;
wherein the composition does not contain organic solvent; and
wherein the composition leaves a surface at least 90% free of streaks when applied to the surface wherein the biocidal quaternary ammonium compound is a dialkyl dimethyl ammonium chloride blend comprising didecyl dimethyl ammonium chloride, dioctyl dimethyl ammonium chloride, and octyl decyl dimethyl ammonium chloride.

2. The composition of claim 1 , further comprising a primary, secondary or tertiary amine.

3. The composition of claim 1 , further comprising bis(3-aminopropyl) alkylamine.

4. The composition of claim 1 , wherein the composition is diluted with water by a factor of 10 to 1000.

5. The composition of claim 4 , wherein the composition is diluted with water by a factor of 50 to 500.

6. A method of residually sanitizing a surface comprising:
contacting a surface, article, and/or substrate with the sanitizing composition of claim 1 .

7. The method of claim 6 , wherein the contacting results in inactivation and/or reduction of infectious agents on the surface, article, and/or substrate.

8. The method of claim 7 , wherein the infectious agents comprise bacteria, viruses, and/or yeasts.

9. A residual sanitizing composition comprising:
a) from about 3000 ppm to about 50 ppm of a unimer biocidal quaternary ammonium compound;
b) from about 7800 ppm to about 130 ppm of an alkyl polyglycoside surfactant;
c) from about 4050 ppm to about 67.5 ppm of a C12 or higher amine oxide; and
d) from about 1200 ppm to about 10 ppm of a chelant;
wherein the composition does not contain organic solvent; and
wherein the composition leaves a surface at least 90% free of streaks when applied to the surface wherein the biocidal quaternary ammonium compound is a dialkyl dimethyl ammonium chloride blend comprising didecyl dimethyl ammonium chloride, dioctyl dimethyl ammonium chloride, and octyl decyl dimethyl ammonium chloride.

10. The composition of claim 9 , further comprising a primary, secondary or tertiary amine.

11. A method of residually sanitizing a surface comprising:
contacting a surface, article, and/or substrate with the sanitizing composition of claim 9 .

12. The method of claim 11 , wherein the contacting results in inactivation and/or reduction of infectious agents on the surface, article, and/or substrate.

13. The method of claim 12 , wherein the infectious agents comprise bacteria, viruses, and/or yeasts.
