Peroxyacid antimicrobial composition
First Claim
1. An aqueous peroxyacid antimicrobial composition consisting essentially of:
- (a) at least about 10 parts per million (ppm) of peroxyglutaric acid; and
(b) at least about 1 ppm of a peroxyacid selected from the group consisting of a C6 -C18 aliphatic peroxyacid, and mixtures thereof;
wherein the aqueous composition has a pH in the range of about 2 to 8.

Abstract
A peroxyacid antimicrobial concentrate and use composition is provided comprising a C5 peroxyacid in combination with a C1 -C4 peroxyacid, a C6 -C18 peroxyacid, or mixtures thereof. The combination of these peracids 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. Sanitizing of substantially fixed, "in-place" processing lines in dairies, breweries, and other food processing operations is one utility of the composition.
