Abstract
The present invention relates to quaternary ammonium disinfecting cleaner compositions comprising a quaternary ammonium compound, an antimicrobial amine, and an anionic scale inhibitor. Beneficially, the compositions provide 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.
Claims36
A disinfectant cleaner composition comprising:
- at least one biocidal quaternary ammonium compound;
- at least one antimicrobial amine;
- and
- an anionic scale inhibitor,
- and wherein the composition remains clear and stable in hard water.
A sanitizing composition comprising:
- at least one biocidal quaternary ammonium compound;
- at least one antimicrobial amine;
- and
- an anionic scale inhibitor,
- wherein the weight % ratio of the at least one biocidal quaternary ammonium compound and the at least one antimicrobial amine is in the range of about 0.1:1 to about 1:1,. and wherein the composition remains clear and stable in hard water.
A method of making a disinfectant cleaning composition comprising:
- combining the following reagents and agitating until a homogenous solution is formed:
- at least one biocidal quaternary ammonium compound;
- at least one antimicrobial amine;
- and
- an anionic scale inhibitor,
- wherein the weight % ratio of the at least one biocidal quaternary ammonium chloride and the at least one antimicrobial amine is in the range of about 0.1:1 to about 1:1,
- and wherein the composition remains clear and stable in hard water.
