A high concentration diester dicarboxylate-peroxide composition comprising:

• at least about 15 wt-% diester dicarboxylate;
• about 0.1 wt-% to about 25 wt-% anionic surfactant, amine oxide surfactant, or a mixture thereof;
• at least about 10 wt-% hydrogen peroxide;
• and
• less than about 30 wt-% total water.

An antimicrobial use solution comprising:

• from about 5 ppm to about 35,000 ppm monoester peroxy dicarboxylic acid;
• from about 2 ppm to about 1,500 ppm anionic surfactant, from about 2 ppm to about 1500 ppm amine oxide surfactant, or a mixture thereof;
• and
• carrier.

A method of reducing population of microorganism on an object, comprising:

• contacting the object with use solution of a high concentration monoester peroxy dicarboxylic acid composition;
• the high concentration composition comprising:
• more than 6 wt-% mono-monoester peroxy dicarboxylic acid;
• at least about 10 wt-% diester dicarboxylate;
• about 0.1 wt-% to about 25 wt-% anionic surfactant, amine oxide surfactant, or a mixture thereof;
• at least about 4 wt-% hydrogen peroxide;
• and
• about 8 to about 55 wt-% total water.

A method of making a high concentration equilibrium mono-monoester peroxy dicarboxylic acid composition comprising:

• formulating
• diester dicarboxylate,
• hydrogen peroxide, and
• water;
• to achieve concentrations of:
• at least about 15 wt-% diester dicarboxylate;
• about 0.1 wt-% to about 25 wt-% anionic surfactant, amine oxide surfactant, or a mixture thereof;
• at least about 10 wt-% hydrogen peroxide;
• and
• less than about 40 wt-% total water;
• equilibrating the formulation;
• thereby making the high concentration equilibrium mono-monoester peroxy dicarboxylic acid composition.
