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.
Claims19
A disinfectant cleaner composition comprising:
- at least one biocidal quaternary ammonium compound;
- at least one antimicrobial amine;
- from about 0.1 wt. % to about 10 wt. % of an anionic scale inhibitor comprising ethanolamine-N,N-bis (methylene phosphonate);
- and
- from about 0.1 wt. % to about 5 wt. % of a sequestering agent comprising methylglycinediacetate;
- wherein the composition remains clear and stable in water which comprises dissolved minerals including calcium, magnesium, and/or manganese.
