A synergistic antimicrobial composition includes an effective amount of at least one furanone, together with other disinfectants, such as, for example, an effective amount of at least one organosilane with quaternary ammonium functionality, and/or an effective amount of at least one quaternary ammonium compound. Additionally, biguanides and disinfectant amines also may be advantageously combined with furanones in an antimicrobial composition.

1. A composition comprising: (a) a sparing amount of at least one furanone; (b) a sparing amount of at least one quaternized organosilane; and (c) a sparing amount of at least one quaternary ammonium compound, wherein the amount of each of components (a), (b) and (c) is sufficient to form, in
1. A composition comprising: (a) a sparing amount of at least one furanone; (b) a sparing amount of at least one quaternized organosilane; and (c) a sparing amount of at least one quaternary ammonium compound, wherein the amount of each of components (a), (b) and (c) is sufficient to form, in combination, a synergistic antimicrobial composition. 2. The composition of claim 1, wherein the sparing amount of furanone is between about 1 μg/L and about 5000 mg/L of the composition. 3. The composition of claim 1, wherein the sparing amount of quaternized organosilane is between about 0.001 weight percent and about 5.0 weight percent of the composition. 4. The composition of claim 1, wherein the sparing amount of quaternary ammonium compound is between about 0.01 weight percent and about 10.0 weight percent of the composition. 5. The composition of claim 1, wherein the composition is effective against microorganisms selected from the group consisting of a fungus, a yeast, a bacterium, and mixtures thereof. 6. The composition of claim 5, wherein the fungus is selected from the group consisting of Alternaria alternata, Aureobasidium pullullans, Cladosporium cladosporioides and Penicillium digitatum. 7. The composition of claim 5, wherein the yeast is Candida albicans. 8. The composition of claim 5, wherein the bacterium is Staphylococcus aureus. 9. The composition of claim 1, wherein the at least one furanone is Furanone 30. 10. The composition of claim 1, wherein the at least one quaternized organosilane is selected from the group consisting of 3-(trimethoxysilyl)propyldimethyl-octadecyl ammonium chloride and 3-(trimethoxysilyl)propylmethyl-di(decyl) ammonium chloride. 11. The composition of claim 1, wherein the at least one quaternary ammonium compound is selected from the group consisting of didecyl dimethyl ammonium chloride, dioctyl dimethyl ammonium chloride, octyl decyl dimethyl ammonium chloride, benzalkonium chloride and alkyl benzyl alkyl dimethyl ammonium chloride. 12. The composition of claim 1, further comprising one or more ingredients selected from the group consisting of: water, a sequestering or complexing agent, a fragrance, an additional disinfectant, and a pH adjustor. 13. A method of cleaning a surface, or a reservoir or conduit that is fluid-filled comprising: providing a synergistic antimicrobial composition comprising: (a) a sparing amount of at least one furanone; (b) a sparing amount of at least one quaternized organosilane; and (c) a sparing amount of at least one quaternary ammonium compound; and applying the composition to the surface, reservoir, or conduit to be cleaned. 14. The method of claim 13, wherein the sparing amount of the at least one furanone is between about 1.0×10-7weight percent and about 0.5 weight percent of the composition. 15. The method of claim 13, wherein the sparing amount of the at least one quaternized organosilane is between about 0.001 weight percent and about 5.0 weight percent of the composition. 16. The method of claim 13, wherein the sparing amount of the at least one quaternary ammonium compound is between about 0.01 weight percent and about 10.0 weight percent of the composition. 17. The method of claim 13, wherein the at least one furanone is Furanone 30. 18. The method of claim 13, wherein the at least one quaternized organosilane is 3-(trimethoxysilyl)propyl-dimethyl-octadecyl ammonium chloride. 19. The method of claim 13, wherein the at least one quaternary ammonium compound is selected from the group consisting of didecyl dimethyl ammonium chloride and benzalkonium chloride.
