Claims24
A composition comprising:
- an effective antimicrobial amount of surfactant peroxycarboxylic acid, wherein the surfactant peroxycarboxylic acid comprises anionic surfactant peroxycarboxylic acid, amphoteric surfactant peroxycarboxylic acid, zwitterionic surfactant peroxycarboxylic acid, or mixture thereof;
- wherein the surfactant peroxycarboxylic acid comprises one or more of an alkyl carboxylate moiety, an alkyl amide moiety, an alkyl sulfonate moiety, an ethoxylate moiety, or a propoxylate moiety;
- about 0.0005 to about 40 wt-% carboxylic acid surfactant;
- an oxidizing agent;
- and
- about 20 wt-% to 70 wt-% of an acidulant.

A method of reducing population of microorganism on an object, the method comprising:
- contacting the object with a surfactant peroxycarboxylic acid composition;
- the composition comprising:
- an effective antimicrobial amount of surfactant peroxycarboxylic acid, wherein the surfactant peroxycarboxylic acid comprises anionic surfactant peroxycarboxylic acid, amphoteric surfactant peroxycarboxylic acid, zwitterionic surfactant peroxycarboxylic acid, or mixture thereof;
- about 0.0005 to about 40 wt-% of a carboxylic acid surfactant;
- an oxidizing agent;
- and
- about 20 wt-% to 70 wt-% of an acidulant.
4 more elements
An article of manufacture comprising:
- a first composition comprising carboxylic acid surfactant and carrier;
- a second composition comprising oxidizing agent;
- directions for combining the first and second compositions;
- wherein combining the first and second compositions provides a surfactant peroxycarboxylic acid composition:
- the surfactant peroxycarboxylic acid composition comprising:
- an effective antimicrobial amount of surfactant peroxycarboxylic acid, wherein the surfactant peroxycarboxylic acid comprises anionic surfactant peroxycarboxylic acid, amphoteric surfactant peroxycarboxylic acid, zwitterionic surfactant peroxycarboxylic acid, or mixture thereof;
- about 0.0005 to about 40 wt-% of the carboxylic acid surfactant;
- an oxidizing agent;
