Abstract:
A composition having antimicrobial activity, the composition comprising an effective antimicrobial amount of a mixture of:(a) about 0.2 wt-% to about 6 wt-% hydrogen peroxide; (b) about 0.5 wt-% to about 80 wt-% carboxylic acid of the formula: R(COOH)n, wherein R comprises hydrogen, alkyl, alkenyl, alicyclic group, aryl, heteroaryl, or heterocyclic group, and n is 1, 2, or 3; (c) about 0.2 wt-% to about 30 wt-% peroxycarboxylic acid of the formula: R(COOOH)n, wherein R comprises hydrogen, alkyl, alkenyl, alicyclic group, aryl, heteroaryl, or heterocyclic group, and n is 1, 2, or 3; and (d) about 0.15 wt-% to 4 wt-% quaternary ammonium compound comprising N-alkyl dimethyl ethyl benzyl ammonium, di-n-alkyl dimethyl ammonium, di-n-alkyl methyl benzyl ammonium salt, or a mixture thereof; the composition comprising 5 to 18 parts by weight of the peroxycarboxylic acid for each part of hydrogen peroxide; wherein the composition, employed at a concentration of about 150 ppm peroxycarboxylic acid, causes greater than 5-log reduction in spores of a microorganism of Bacillus cereus group in about 10 min at 40Â° C.
