1. A composition consisting of:
- about 0.5 to about 5 wt-% peroxyoctanoic acid;
about 1 to about 10 wt-% octanoic acid;
about 5 to about 97 wt-% water;
about 1 to about 20 wt-% of an anionic surfactant selected from the group consisting of alkyl sulfonate, linear alkyl benzene sulfonic acid, secondary alkane sulfonate, alkylated diphenyl oxide disulfonate, alkyl ether sulfate, and mixtures thereof;
about 5 to about 10 wt-% hydrogen peroxide and a persulfate;
about 15 to about 35 wt-% sulfuric acid or methanesulfonic acid; and
about 1 to about 5 wt-% sequestrant;
the composition being in the form of a microemulsion, the microemulsion comprising droplets of a diameter of 100 nanometers or less.

Abstract
The present invention relates to compositions including medium chain peroxycarboxylic acid, methods for making these compositions, and methods for reducing the population of a microorganism. The compositions can include advantageously high levels of the medium chain peroxycarboxylic acid, can be readily made, and/or can exhibit reduced odor.
