## 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.

## Claims

### Claim 1

A sanitizing composition comprising:
from about 0.7 wt. % to about 40.0 wt. % of a a dialkyl quaternary ammonium compound free of benzyl or aromatic quaternary substituents;
from about 8 wt. % to about 80.0 wt. % of an alkyl polyglycoside surfactant;
from about 9 wt. % to about 90.0 wt. % of a C12 or higher amine oxide surfactant; and
from about 0.1 wt. % to about 4.0 wt. % of a chelant;
wherein the composition does not contain organic solvent and wherein the alkyl polyglycoside surfactant having a critical micelle concentration (CMC) of 1000 or more does not interfere with the biocidal activity of the quaternary ammonium compound.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 4)

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

### Claim 6 (depends on 1)

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

### Claim 7 (depends on 6)

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

### Claim 8 (depends on 6)

The method of claim 6, wherein the infectious agents comprise one or more of bacteria, viruses and/or yeasts.

### Claim 9

A residual sanitizing composition comprising:
from about 3000 ppm to about 50 ppm of a dialkyl quaternary ammonium compound free of benzyl or aromatic quaternary substituents;
from about 7800 ppm to about 130 ppm of an alkyl polyglycoside surfactant;
from about 4050 ppm to about 67.5 ppm of an C12 or higher amine oxide surfactant; and
from about 1200 ppm to about 10 ppm of a chelant,
wherein the composition does not contain organic solvent and wherein the alkyl polyglycoside surfactant having a critical micelle concentration (CMC) of 1000 or more does not interfere with the biocidal activity of the quaternary ammonium compound.

### Claim 10 (depends on 9)

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

### Claim 11 (depends on 9)

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

### Claim 12 (depends on 11)

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

### Claim 13 (depends on 11)

The method of claim 11, wherein the infectious agents comprise bacteria, viruses, and/or yeasts.
