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.
Claims13
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.

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,
