[ EN ]

What is claimed is:

1. A concentrated multi-purpose cleaning composition comprising:

between about 1 wt.% and about 60 wt.% of an anionic sulfonated surfactant;

between about 1 wt.% and about 30 wt.% of a solvent having a less than 5% (wt./wt.)

solubility in water;

a carrier;

wherein the anionic sulfonated surfactant and solvent are in a ratio between about 3: 1 and about 1 :3; and wherein the composition has a pH of between about 0.5 and about 1.5.

2. The composition of claim 1, wherein the composition has less than about 0.1 wt.% of a peroxide.

3. The composition of any one of claims 1-2, wherein the composition further comprises a chelant in an amount between about 0.01 wt.% and about 10 wt.%.

4. The composition of any one of claims 1-3, wherein the solvent comprises an aromatic alcohol, an aromatic glycol ether, an alkylene glycol ether, or a mixture thereof.

5. The composition of any one of claims 1-4, wherein the solvent comprises benzyl alcohol, a phenoxyethanol, a phenoxypropanol, dipropylene glycol n-butyl ether, tripropylene glycol butyl ether or a mixture thereof.

6. The composition of any one of claims 1-5, wherein the composition has a pH between about 2 and about 3.2 when diluted for use.

7. The composition of any one of claims 1-6, wherein the anionic sulfonated surfactant comprises a C8-C22 alkylbenzene sulfonic acid, sulfonated oleic acid, secondary alkane sulfonate, a sulfosuccinate, or mixture thereof.

8. The composition of any one of claims 1-7, wherein the composition provides at least about 40% soil removal of an oily, industrial soil, and/or at least about 70% soil removal of a food soil.

9. The composition of any one of claims 1-7, wherein the composition provides :

(a) at least about a 3-log reduction in feline calicivirus in the presence of about 5% soil and about 400 ppm hard water after about 30 seconds;

(b) at least about a 5-log reduction in staphylococcus aureus in the presence of about 5% soil and about 400 ppm hard water after about 30 seconds; or

(c) both (a) and (b).

10. The composition of any one of claims 1-9, wherein the composition provides complete inactivation of feline calicivirus in 30 seconds or less.

11. The composition of any one of claims 1-10, wherein the composition further comprises a buffering agent, a lubricant, a coupling agent, a defoaming agent, a dye, a fragrance, a foaming agent, a hydrotrope, a pH adjusting agent, a solubilizer, an additional surfactant, a wetting agent, or mixture thereof.

12. The composition of claim 11, wherein the lubricant is in a concentration of between about 1 wt.% and about 20 wt.% and comprises glycerin, propylene glycol, or mixture thereof.

13. A ready -to-use multi-purpose cleaning composition comprising:

between about 0.01 wt.% and about 2 wt.% of an anionic sulfonated surfactant;

between about 0.01 wt.% and about 2 wt.% of a solvent having a less than 5% (wt./wt.) solubility in water;

between about 78 wt.% and about 96 wt.% of a carrier;

wherein the composition has a pH of less than about 3.5; and

wherein the composition provides at least about 3 log reduction in a microbial population in about 15 minutes or less.

14. The composition of claim 13, wherein the composition further comprises a chelant in an amount between about 0.01 wt.% and about 1 wt.%.

15. The composition of any one of claims 13-15, wherein the solvent comprises an aromatic alcohol, an aromatic glycol ether, an alkylene glycol ether, or a mixture thereof; wherein the anionic sulfonated surfactant comprises a C8-C22 alkylbenzene sulfonic acid, sulfonated oleic acid, secondary alkane sulfonate, a sulfosuccinate, or mixture thereof.

16. The composition of any one of claims 13-15, wherein the composition provides at least about 40% soil removal of an oily, industrial soil, and/or at least about 70% soil removal of a food soil.

17. The composition of any one of claims 13-16, wherein the composition further comprises a buffering agent, a lubricant, a coupling agent, a defoaming agent, a dye, a fragrance, a foaming agent, a hydrotrope, a pH adjusting agent, a solubilizer, an additional surfactant, a wetting agent, or mixture thereof.

18. The composition of claim 17, wherein the lubricant is in a concentration of between about 0.05 wt.% and about 1 wt.% and comprises glycerin, propylene glycol, or mixture thereof.

19. A method of cleaning a surface comprising:

contacting a surface with a composition of any one of claims 1-18.

20. The method of claim 19, wherein the contacting is performed by wiping, spraying, pouring, mopping, or a combination thereof.

21. The method of any one of claims 19-20, wherein the surface is a bath, a carpet, a container, a counter, a curtain, a door, a door handle, a drain, a fabric, a floor, a fluid tank, a hospital partition, a mirror, a monitor, a pipe, a rail, a shower, a sink, a textile, a thermostat, a touch screen, an upholstery, a wall, a window, a woven surface, and a non-woven surface or a combination thereof.

22. The method of claim 21, wherein the composition leaves no visible streaking when applied to the surface.

23. The method of any one of claims 19-22, wherein the composition is in contact with the surface for at least 60 seconds, and wherein the composition provides at least about a 3
