Abstract

The invention relates to fast-acting viricidal compositions and methods of using the same, wherein the compositions are capable of removing soil and effectively inactivating a wide variety of viral pathogens, particularly small, non-enveloped viruses such as poliovirus and norovirus. The compositions are especially useful on hard surfaces, and can easily be applied to a service to provide rapid viricidal efficacy.

Claims (14)

1. A concentrated viricidal composition comprising:

between about 5 wt. % and about 10 wt. % of an anionic sulfonated surfactant comprising dodecylbenzene sulfonic acid;

between about 80 wt. % and about 90 wt. % of an aromatic alcohol solvent comprising benzyl alcohol;

between about 5 wt. % and about 10 wt. % of a nonionic surfactant comprising an ethylene oxide/propylene oxide (EO/PO) block copolymer; and

between about 0.01 wt. % and about 0.5 wt. % of a water conditioning agent comprising a diphosphonic acid; and

between about 0.01 wt. % and about 0.05 wt. % of sodium hydroxide;

wherein the ratio of aromatic alcohol solvent to anionic sulfonated surfactant is between about 8:1 and about 15:1;

wherein the composition has less than about 0.1 wt. % of added peroxide;

wherein the composition provides a pH of less than about 3 in a use solution formed with between about 90 wt. % water to about 98 wt. % water; and

wherein the composition provides at least about 3.5 log reduction in polio in about 1 minute or less.

2. The composition of claim 1 , wherein the composition further comprises an additional solvent.

3. The composition of claim 2 , wherein the additional solvent comprises a phenoxypropanol, dipropylene glycol n-butyl ether, tripropylene glycol butyl ether, or a mixture thereof.

4. The composition of claim 1 , wherein the composition provides a pH between about 2 and about 3 in the use solution.

5. The composition of claim 1 , wherein the composition further comprises an additional surfactant, an additional pH modifier, a buffering agent, a dye, a fragrance, a foaming agent, a surface active agent, a solubilizer, a coupling agent, a hydrotrope, a defoaming agent, or mixture thereof.
