Abstract

Antimicrobial, hard surface cleaning compositions that effectively clean and reduce microorganisms on a surface without resulting in unacceptable filming and/or streaking residue on the surface, generally comprise (a) cationic antimicrobial active; (b) nitrogen-containing polymer; and (c) surfactant. Preferred antimicrobial, hard surface cleaning compositions for use in no-rinse cleaning methods comprise (a) from about 0.001% to about 0.5%, by weight of the composition, of surfactant; (b) cationic antimicrobial active; and (c) nitrogen-containing polymer. Methods of cleaning and reducing microorganisms on hard surfaces comprises contacting the surfaces with such compositions and preferably allowing the compositions to dry on the surface without rinsing the composition from the surface using water or other rinsing solution.

Claims

1. An antimicrobial, hard surface cleaning composition comprising:

(a) from about 0.001% to about 15%, by weight of said composition, of a surfactant selected from the group consisting of nonionic surfactant, anionic surfactant, zwitterionic surfactant, amphoteric surfactant, and mixtures thereof;

(b) a cationic antimicrobial active selected from the group consisting of biguanide compounds, bis-biguanide compounds, polymeric biguanides and mixtures thereof;

(c) a nitrogen-containing polymer, wherein said nitrogen-containing polymer is selected from the group consisting of;

(i) polyalkyleneimines and derivatives;

(ii) modified polyamines having the formulae;

2. A cleaning composition according to claim 1, wherein said surfactant is present at a level of from about 0.001% to about 0.5%, by weight of the composition.

3. A cleaning composition according to claim 2, wherein said surfactant is present at a level of from about 0.005% to about 0.3%, by weight of the composition.

4. A cleaning composition according to claim 1, wherein said surfactant is a nonionic surfactant.

5. A cleaning composition according to claim 4, wherein said nonionic surfactant is an alkyl polyglucoside surfactant.

6. A cleaning composition according to claim 1, wherein said cationic antimicrobial active is present at a level of from about 0.005% to about 1%, by weight of the composition.

7. A cleaning composition according to claim 6, wherein said cationic antimicrobial active is present at a level of from about 0.005% to about 0.5%, by weight of the composition.

8. A cleaning composition according to claim 1, wherein said nitrogen-containing polymer is present at level of from about 0.005% to about 1%, by weight of said composition.

9. A cleaning composition according to claim 8, wherein said nitrogen-containing polymer is present at a level of from about 0.005% to about 0.3%, by weight of said composition.

10. A cleaning composition according to claim 1, wherein said nitrogen-containing polymer has a molecular weight of from about 50,000 to about 15,000,000 Daltons.

11. A cleaning composition according to claim 10, wherein said nitrogen-containing polymer has a molecular weight of from about 350,000 to about 15,000,000 Daltons.

12. A cleaning composition according to claim 1, wherein said polymeric biguanide compound is selected from the group consisting of poly(hexamethylene biguanide), poly(hexamethylene biguanide)hydrochloride, poly(hexamethylene biguanide)hydrobromide, and poly(hexamethylene biguanide)hydrogen sulfate.

13. A cleaning composition according to claim 1;

wherein said bis-biguanide compound is a chlorhexidine compound.

14. A cleaning composition according to claim 1 further comprising a quaternary cationic antimicrobial active.

15. A kit for cleaning and reducing microorganisms on hard surfaces, said kit comprising:

a cleaning pad comprising an absorbent layer, wherein said cleaning pad is impregnated with the cleaning composition of claim 1.

16. The kit for cleaning and reducing microorganisms on hard surfaces of claim 15, wherein said pad further comprises an attachment layer.

17. The kit for cleaning and reducing microorganisms on hard surfaces of claim 16, wherein said pad further a scrubbing layer.

18. The kit for cleaning and reducing microorganisms on hard surfaces of claim 15, wherein said cleaning pad has a total fluid capacity less than 100 g.

19. The kit for cleaning and reducing microorganisms on hard surfaces of claim 15, wherein said cleaning pad has a total fluid capacity of at least about 100 g.
