Abstract

Described is An aqueous disinfectant and hard surface cleaning composition comprising:

an effective disinfecting amount of a quaternary ammonium compound;

an effective amount of a spore forming microbial composition; and

an effective water dispersing amount of a surfactant.

The composition is used to clean a hard surface containing a diverse microbial flora. The composition cleans and disinfects by killing off undesirable microorganisms which may be causing offensive odors and leaves behind Bacillus spores which will then germinate and degrade any remaining ongoing residues without creating offensive odors.

Claims

1. An aqueous disinfectant and hard surface cleaning composition consisting essentially of:

an effective disinfecting amount of a quaternary ammonium compound;

an effective spore forming amount of a Bacillus microbial composition; and

an effective water dispersing amount of a surfactant other than the quaternary ammonium compound.

3. The composition of claim 1 wherein the cleaning composition is present in the amount of 1 to 10% by wt. with the remainder of the composition being 90 to 99% by wt water.

4. The composition of claim 3 wherein the quaternary ammonium compound is present in the amount of 5.5%;

the spore forming microbial composition is present in the amount of 0.01%;

the additional surfactant is present in the amount of 6.3%;

and the pH ranges from 6 to 8.

5. The composition of claim 1 consisting essentially of the following materials by weight:

6. The composition of claim 1 consisting essentially of the following materials:

7. A method of cleaning a soiled hard surface containing a diverse microbial flora comprising applying the composition of claim 1 to the surface and drying the surface, thereby cleaning and disinfecting the surface.

8. The method of claim 7 wherein the hard surface contains microbes, selected from the group consisting of Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella choleraesius and Escherichia coli.

9. The method of claim 7 wherein the soiled surface is comprised of blood serum as an organic soil load in the composition which is diluted in hard water containing 100-400 ppm CaCO₃, thereby demonstrating efficacy as a one-step cleaner disinfectant.

10. The method of claim 7 consisting essentially of the following materials:

11. The method of claim 7 consisting essentially of the following materials:

13. The composition of claim 1, wherein the quaternary ammonium compound is a dialkyl of from 6-18 carbon atoms, dialkyl of 1 to 4 carbon atoms ammonium compound.

15. The composition of claim 1, wherein the Bacillus material is comprised of Bacillus subtilis.

2. A concentrated aqueous disinfectant and hard surface cleaning composition, useful by diluting with water, consisting essentially of:

an effective disinfecting amount of a quaternary ammonium compound;

an effective spore forming amount of Bacillus microbial composition;

an effective water dispersing amount of [an additional material,] a surfactant other than the quaternary ammonium compound; and

an effective thickening amount of a thickening agent.

14. The composition of claim 2, wherein the quaternary ammonium compound is a dialkyl of from 6-18 carbon atoms, dialkyl of 1 to 4 carbon atoms ammonium compound.

16. The composition of claim 2, wherein the Bacillus material is comprised of Bacillus subtilis.

12. An aqueous disinfectant and hard surface cleaning composition consisting essentially of by weight:
