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.

Claims

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; and

about 5 to about 10 wt-% hydrogen peroxide.

2. The composition of claim 1, further consisting of

about 3 to about 20 wt-% anionic surfactant.

3. The composition of claim 1, consisting of at least about 2 parts by weight of peroxyoctanoic acid for each 7 parts by weight of octanoic acid.

4. The composition of claim 1, further consisting of fragrance, the fragrance comprising amyl acetate, iso-bornyl acetate, alkyl salicylate, or mixture thereof.
