- 11. The concentrate composition of claim 10 wherein said C.sub.6 -C.sub.18 carboxylic acid is selected from the group consisting of octanoic acid, decanoic acid, adipic acid, sebacic acid, and mixtures thereof.
- 12. The concentrate composition of claim 1 further consisting of hydrogen peroxide.
- 13. The concentrate composition of claim 12 wherein said concentrate is about 1 to 50 wt-% of said hydrogen peroxide.
- 14. The concentrate composition of claim 1 wherein said composition can form a use solution having a pH of about 3 to 7 and the microbial population is reduced in less than 30 seconds.
- 15. A peroxyacid antimicrobial concentrate composition consisting essentially of:
- (a) about to 1 to 25 wt-% of peroxyglutaric acid;
- (b) about 0.01 to 10 wt-% of a peroxyacid of the structure R.sub.1 --CO.sub.3 H, wherein R.sub.1 comprises an aliphatic 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 that can achieve a 5 log reduction in a microbial population at a pH in the range of about 3 to 7.
- 16. The concentrate composition of claim 15 wherein said peroxyacid of (b) is a peroxyfatty acid having about 8 to 12 carbon atoms per molecule.
- 17. The concentrate composition of claim 16 wherein said peroxyfatty acid is peroxyoctanoic acid, peroxydecanoic acid, or mixtures thereof.
- 18. The concentrate composition of claim 16 wherein the weight ratio of said peroxyglutaric acid to said peroxyfatty acid is about 20:1 to 2:1.
- 19. The concentrate composition of claim 15 wherein said hydrotrope is n-octanesulfonate.
- 20. The concentrate composition of claim 16 further consisting of about 5 to 50 wt-% of a carboxylic acid selected from the group consisting of a fatty acid, glutaric acid, and mixtures thereof.
- 21. The concentrate composition of claim 20 wherein said fatty acid is octanoic acid, decanoic acid, or mixtures thereof.
