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.
Claims34
A disinfectant cleaner composition comprising:
- at least one biocidal quaternary ammonium compound;
- at least one antimicrobial amine;
- and
- from about 0.1 wt.-% to about 2 wt.-% an anionic scale inhibitor comprising ethanolamine-N,N-bis(methylene phosphonate).
A sanitizing composition comprising:
- at least one biocidal quaternary ammonium compound;
- at least one antimicrobial amine;
- and
- from about 0.1 wt.-% to about 2 wt.-% of an anionic scale inhibitor, comprising ethanolamine-N,N-bis(methylene phosphonate), 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
- a solvent.
A sanitizing composition comprising:
- a) from about 1 wt.-% to about 30 wt.-% of at least one biocidal quaternary ammonium compound;
- b) from about 1 wt.-% to about 30 wt.-% of at least one antimicrobial amine;
- and
- c) from 1 wt.-% to about 10 wt.-% of an anionic scale inhibitor comprising ethanolamine-N,N-bis(methylene phosphonate), 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
- a solvent.
A method of making a disinfectant cleaning composition, comprising:
- combining the following reagents and agitating until a homogenous solution is formed:
- a) at least one biocidal quaternary ammonium compound;
- b) at least one antimicrobial amine;
- and
- c) an anionic scale inhibitor comprising ethanolamine-N,N-bis(methylene phosphonate),
- 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 remains clear and stable when diluted with water which comprises dissolved minerals including calcium, magnesium, and/or manganese.
