Abstract

A disinfecting composition comprising a quaternary ammonium acid compound and hydrogen peroxide is disclosed. An embodiment of the composition comprises a quaternary ammonium acid compound in a hydrogen peroxide/water solution. In addition, the composition can further comprise an acid. In addition, the composition does not comprise a cationic polymer. The disclosure also provides methods of using the same to kill or inhibit the growth of microorganisms, such as bacteria, viruses, fungi, mildew, and mold. The disclosure also provides for methods of disinfecting a substrate, preferably a hard surface, comprising applying a disinfecting composition of the invention to the substrate.

First claim

The invention claimed is:

1. A composition comprising a quaternary ammonium acid compound and hydrogen peroxide, wherein the composition does not comprise a cationic polymer,
wherein the quaternary ammonium acid compound is a compound having the formula (I):

wherein R 1 is a benzyl group or a C 1-22 alkyl or aryl-substituted alkyl group;
R 2 is selected from the group consisting of C 1-22 alkyl or aryl-substituted alkyl group, benzyl group, and —[(CH 2 ) 2 —O] n —R 5 , wherein n is an integer from 1 to 20 and R 5 is selected from the group consisting of hydrogen, phenyl, and alkyl-substituted phenyl;
R 3 and R 4 are independently C 1-22 alkyl; and
M − is CH 3 COO − , H 2 PO 4 − , C 4 H 5 O 6 − , C 6 H 9 O 4 − , HC 2 O 4 − , or H 2 NSO 3 − ,

wherein the quaternary ammonium acid compound is free of chloride, and
wherein the composition has a pH <7.

2. The composition according to claim 1 , further comprising an acid.

3. The composition according to claim 1 , wherein R 1 and R 2 are the same benzyl groups or C 1-22 alkyl or aryl-substituted alkyl groups.

4. The composition according to claim 1 , wherein R 3 and R 4 are the same C 1-22 alkyl groups.

5. The composition according to claim 1 , wherein R 1 and R 2 are C 10 alkyl, and R 3 and R 4 are methyl.

6. A method of killing or inhibiting growth of microorganisms or disinfecting a surface by applying the composition of claim 1 to a surface.

7. The method according to claim 6 , wherein the microorganisms comprise one or more of Gram positive bacteria, Gram negative bacteria, viruses, fungi, mildew, or mold.

8. The method according to claim 6 , wherein the microorganisms comprise one or more of Staphylococcus, Pseudomonas, hepatitis, rotavirus, rhinovirus, or TB.

9. The method according to claim 6 , wherein the microorganisms are P. aeruginosa.

10. The method of claim 6 , wherein the surface is a floor, wall, countertop, appliance, or fixture.

11. A wipe saturated with a composition of claim 1 .

12. The wipe of claim 11 , wherein the wipe is disposable, and wherein the wipe expresses or releases the composition on to a surface as the wipe is run across the surface to be treated.

13. The composition of claim 1 , comprising about 1% to about 42.5% by weight of quaternary ammonium acid compound and about 2% to about 58% by weight of hydrogen peroxide.

14. The composition of claim 1 , comprising about 1% to about 6.4% by weight of quaternary ammonium acid compound.

15. The composition of claim 1 , wherein the quaternary ammonium acid compound is formed from reacting a quaternary ammonium carbonate/ bicarbonate compound with an acid prior to the addition of hydrogen peroxide,
wherein the quaternary ammonium carbonate/ bicarbonate compound is a compound having the formula (II)

wherein R 1 is a benzyl group or a C 1-20 alkyl or aryl-substituted alkyl group;
R 2 is selected from the group consisting of C 1-20 alkyl or aryl-substituted alkyl group, benzyl group, and —[(CH 2 ) 2 —O] n —R 5 , wherein n is an integer from 1 to 20 and R 5 is selected from the group consisting of hydrogen, phenyl, and alkyl-substituted phenyl;
R 3 and R 4 are independently C 1-20 alkyl, and

wherein the acid is selected from the group consisting of acetic acid, phosphoric acid, tartaric acid, adipic acid, sulfamic acid, or oxalic acid.

16. The composition of claim 15 , where the quaternary ammonium carbonate/bicarbonate compound is didecyl dimethyl ammonium carbonate/ bicarbonate.

17. The composition of claim 1 , wherein the composition is free of chelating agent.

18. The composition of claim 1 , wherein the quaternary ammonium acid compound is a compound having the formula (I):

wherein R 1 is a benzyl group or a C 1-22 alkyl or aryl-substituted alkyl group;
R 2 is selected from the group consisting of C 1-22 alkyl or aryl-substituted alkyl group, benzyl group, and —[(CH 2 ) 2 —O] n —R 5 , wherein n is an integer from 1 to 20 and R 5 is selected from the group consisting of hydrogen, phenyl, and alkyl-substituted phenyl;
R 3 and R 4 are independently C 1-22 alkyl; and
M − is CH 3 COO − , H 2 PO 4 − , C 6 H 9 O 4 − , HC 2 O 4 − , or H 2 NSO 3 − .

19. The composition of claim 1 , wherein the composition does not comprise a surfactant.

20. The composition of claim 1 , wherein active components in the composition consists of the quaternary ammonium acid compound and hydrogen peroxide.
