Peroxyacid antimicrobial composition
First Claim
1. A peroxyacid antimicrobial concentrate composition comprising:
- (a) about 0.01 to 25 wt. % of a C1 -C4 peroxycarboxylic acid;
(b) about 0.01 to 10 wt. % of a peroxyacid of the structure R1 --CO3 H, wherein R1 comprises a linear, saturated hydrocarbon chain having about 5 to 17 carbon atoms;
(c) about 0.1 to 30 wt. % of a hydrotrope coupling agent capable of solubilizing said peroxyacid of (b) in the concentrate and when the concentrate is diluted with water; and
(d) about 1 to 50 wt. % of hydrogen peroxide;
wherein the concentrate composition is capable of being diluted with a major proportion of water to form an antimicrobial sanitizing use solution having a pH in the range of about 3 to 7.

Abstract
A peroxyacid antimicrobial concentrate and use composition is provided comprising a C1 to C4 peroxycarboxylic acid, and a C6 to C18 peroxyacid. The combination of these acids produces a synergistic effect, providing a much more potent biocide than can be obtained by using these components separately. Other components can be added to the composition such as hydrotrope coupling agents, stabilizers, etc. An effective antimicrobial use solution is formed at low concentrations when the concentrate composition is diluted with water to a pH in the range of about 2 to 8. Sanitizing of substantially fixed, "in-place" processing lines in dairies, breweries, and other food processing operations is one utility of the composition.
