Abstract

The present disclosure relates to multi-purpose cleaning compositions, methods of manufacturing the multi-purpose cleaning compositions, and methods of using the multi-purpose cleaning compositions to clean a surface. The composition contains anionic sulfonated surfactant, solvent, a carrier, and a chelant. Beneficially the multi-purpose cleaning compositions are capable of removing soil and providing antimicrobial activity. The compositions are especially useful on hard surfaces and are preferably low streaking.

Claims

What is claimed is:

1. A concentrated multi-purpose cleaning composition comprising: between about 7 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, wherein the solvent comprises benzyl alcohol, phenoxyethanol, or a mixture thereof; a carrier; wherein the composition further comprises a chelant in an amount between about 0.01 wt.% and about 10 wt.%; wherein the anionic sulfonated surfactant and solvent are in a ratio between about 3:1 and about 1:1; 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 has a pH between about 2 and about 3.2 when diluted for use.

4. The composition of any one of claims 1-3, wherein the anionic sulfonated surfactant comprises a C -C alkylbenzene sulfonic acid, sulfonated oleic acid, secondary alkane sulfonate, a sulfosuccinate, or mixture thereof.

5. The composition of any one of claims 1-4, 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.

6. The composition of any one of claims 1-5, 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).

7. The composition of any one of claims 1-6, wherein the composition provides complete inactivation of feline calicivirus in 30 seconds or less.

8. The composition of any one of claims 1-7, 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.

9. The composition of claim 8, wherein the lubricant is in a concentration of between about 1 wt.% and about 20 wt.% and comprises glycerin, propylene glycol, or mixture thereof.

10. 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, wherein the solvent comprises benzyl alcohol, phenoxyethanol, or a mixture thereof; a carrier in a concentration to q.s.; wherein the composition further comprises a chelant in an amount between about 0.01 wt.% and about 1 wt.%; wherein the composition has a pH of less than about 3.5; wherein the anionic sulfonated surfactant and solvent are in a ratio between about 3:1 and about 1:1; and wherein the composition provides at least about 3 log reduction in a microbial population in about 15 minutes or less.

11. The composition of claim 10, wherein the anionic sulfonated surfactant comprises a C -C alkylbenzene sulfonic acid, sulfonated oleic acid, secondary alkane sulfonate, a sulfosuccinate, or mixture thereof.

12. The composition of any one of claims 10-11, 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.

13. The composition of claim 12, 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.

14. A method of cleaning a surface comprising: contacting a surface with a composition of any one of claims 1-13.

15. The method of claim 14, wherein the contacting is performed by wiping, spraying, pouring, mopping, or a combination thereof.

16. The method of any one of claims 14-15, 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.

17. The method of any one of claims 14-16, wherein the composition is in contact with the surface for at least 60 seconds, and wherein the composition provides at least about a 3 log reduction and inactivates a virus after about 60 seconds and/or provides at least about a 3.5 log reduction in a bacterial population after about 3 minutes.

18. A method of manufacturing the multi-purpose cleaning composition of any one of claims 1-13 comprising: combining and mixing the anionic sulfonated surfactant, the solvent, and the carrier.

19. The method of claim 18, further comprising adjusting the pH of the composition with a pH modifier to a desired pH.

20. The method of any one of claims 18-19, further comprising diluting the multi-purpose cleaning composition. By the Attorneys for the Applicant SPRUSON & FERGUSON Ecolab USA Inc.
