Claims19
A sanitizing/disinfecting composition comprising:
- a) a quaternary ammonium compound, having the general formula:
- wherein
- R2 is benzyl or C6-18-alkyl;
- R3 is C1-18-alkyl or —[(CH2)2—O]nR6 where n=1-20;
- R4 and R5 independently of one another are CI-Li-alkyl;
- R6 is hydrogen or unsubstituted or substituted phenyl;
- and
- A− is a monovalent anion or one equivalent of a polyvalent anion of an inorganic or organic acid, wherein the quaternary ammonium compound comprises a didecyldimethyl ammonium compound, a dioctyldimethyl ammonium compound, a mixture of a didecyldimethyl ammonium compound and an alkyldimethylbenzyl ammonium compound, or a mixture of a dioctyldimethyl ammonium compound and an alkyldimethylbenzyl ammonium compound;
- b) a polyalkylenebiguanide;
- c) a solvent comprising an organic solvent;
- and
- d) at least one surfactant comprising an ethoxylated ester;
- wherein the quaternary ammonium compound is present in an effective amount of about 150 ppm up to about 400 ppm, the polyalkylenebiguanide is present in an amount of about 150 ppm up to about 550 ppm, and the at least one surfactant is present in an amount from 0.01 wt. % to 5 wt %, based upon the weight of the sanitizing/disinfecting composition, whereby the quaternary ammonium compound and the polyalkylenebiguanide provide the composition with a Log10 kill rate greater than 5 against Staphylococcus aureus, Salmonella enterica, or Pseudomonas aeruginosa,
- wherein the Log10 kill is measured using test method for Pre-Saturated Towelette for Hard-Surface Disinfection (Modified AOAC 961.0 2, AOAC Germicidal Spray Products as Disinfectants);
- and
- e) an alkyl polyglucoside comprising C8-C10 alkyl polyglucoside.
