Activated disinfectant hydrogen peroxide compositions

A ready-to-use hydrogen peroxide, disinfectant solution comprising:

• a biocidal amount of hydrogen peroxide from 0.05 to 2 weight percent of the total solution,
• a non-surfactant organic sulfonic acid or salt thereof from 0.05 to 5.0 weight percent of the total solution,
• a non-ionic surfactant from 0.05 to 3.0 weight percent of the total solution,
• an optional acid other than the non-surfactant organic sulfonic acid from 0.05 to 6.0 weight percent of the total solution, and
• water,
• wherein the ready-to-use hydrogen peroxide, disinfectant solution is free of an anionic surfactant,
• wherein the ready-to-use hydrogen peroxide, disinfectant solution has a pH from 0.5 to 4.0, and
• wherein the hydrogen peroxide source, the non-surfactant organic sulfonic acid or salt thereof, the non-ionic surfactant, and the optional acid provide the ready-to-use hydrogen peroxide, disinfectant solution with a Log10 microbial reduction ≥4 within a 3-minute contact time against Staphylococcus aureus (Sa),
• wherein the non-surfactant organic sulfonic acid or salt thereof is selected from the group consisting of methane sulfonic acid, benzene sulfonic acid, toluene sulfonic acid, xylene sulfonic acid, ethylbenzene sulfonic acid or mixtures thereof, and
• wherein the optional acid is glutaric acid, citric acid, phosphoric acid, etidronic acid, or mixtures thereof.

A method of disinfecting a surface of microorganisms, the method comprising:

• contacting said surface with a disinfecting composition comprising of
• (i) a biocidal amount of hydrogen peroxide from 0.05 to 2 weight percent of the disinfecting composition,
• (ii) a non-surfactant organic sulfonic acid or salt thereof from 0.05 to 5.0 weight percent of the disinfecting composition,
• (iii) a non-ionic surfactant from 0.05 to 3.0 weight percent of the disinfecting composition,
• (iv) an optional acid other than the non-surfactant organic sulfonic acid from 0.05 to 6.0 weight percent of the disinfecting composition, and
• (v) water,
• wherein the disinfecting composition is free of an anionic surfactant,
• wherein the disinfecting composition has a pH from 0.5 to 4.0,
• wherein the hydrogen peroxide source, the non-surfactant organic sulfonic acid or salt thereof, the non-ionic surfactant, and the optional acid provide the disinfecting composition with a Log10 microbial reduction ≥4 within a 3-minute contact time against Staphylococcus aureus (Sa),
• wherein the non-surfactant organic sulfonic acid or salt thereof is selected from the group consisting of methane sulfonic acid, benzene sulfonic acid, toluene sulfonic acid, xylene sulfonic acid, ethylbenzene sulfonic acid or mixtures thereof, and
• wherein the optional acid is glutaric acid, citric acid, phosphoric acid, etidronic acid, or mixtures thereof, and
• wherein said surface is contacted for an amount of time effective to kill a majority of the microbes located on the surface.

A two-part disinfectant, comprising:

• a first container including a non-surfactant organic sulfonic acid or salt thereof, a non-ionic surfactant, and an optional acid other than the non-surfactant organic sulfonic acid;
• and
• a second container including a biocidal amount of hydrogen peroxide from 2 to 8 weight percent of the disinfectant, and water;
• wherein the two-part disinfectant is free of an anionic surfactant,
• wherein the two-part disinfectant provides a ready-to-use, disinfectant solution with a pH from 0.5 to 4.0;
• wherein the two-part disinfectant provides the ready-to-use, disinfectant solution with 0.05 to 2 weight percent of hydrogen peroxide,
• wherein the two-part disinfectant provides the ready-to-use, disinfectant solution with 0.05 to 5.0 weight percent of non-surfactant organic sulfonic acid or salt thereof,
• wherein the two-part disinfectant provides the ready-to-use, disinfectant solution with 0.05 to 3.0 weight percent of non-ionic surfactant,
• wherein the two-part disinfectant provides the ready-to-use, disinfectant solution with 0.05 to 6.0 weight percent of optional acid, and
• wherein the hydrogen peroxide source, the non-surfactant organic sulfonic acid or salt thereof, the non-ionic surfactant, and the optional acid of the two-part disinfectant provides the ready-to-use, disinfectant solution with a Log10 microbial reduction ≥4 within a 3-minute contact time against Staphylococcus aureus (Sa).
