Abstract

The present invention relates to a disinfecting composition which requires a shorter contact time to be effective than similar compositions. Also, provided is a method of disinfecting a surface with the disinfecting composition where a shorter contact time is needed to disinfect the surface.

First claim

What is claimed is:

1. A disinfectant composition having a 5 minute or less contact kill time as measured by the Use Dilution Test of 2012, said composition consisting of:
a) a disinfecting component being a mixture of:
(i) a dimethyldialkyl ammonium compound, and
(ii) an alkyl dimethyl benzyl ammonium compound, wherein the components are in a weight ratio of component (i) to component (ii) between 4:1 to 1:2;

b) a nonionic or cationic surfactant;
c) a solvent;
d) optionally a sequestration agent;
e) optionally a pH adjuster;
f) optionally a corrosion inhibitor;
g) optionally a complexing agent;
h) optionally an auxiliary;
i) optionally a preservative,
j) optionally a fragrance; and
k) optionally a colorant.

2. The disinfectant composition according to claim 1 , wherein the nonionic surfactant is an alkoxylated alcohol surfactant having 2-8 moles of alkoxylation and the cationic surfactant is an alkyl trimethyl ammonium salt.

3. The disinfectant composition according to claim 2 , wherein each of the alkyl groups of the dimethyldialkyl ammonium compound contains between 8 and 10 carbon atoms and the alkyl group of the alkyl dimethyl benzyl ammonium compound contains between 12 and 18 carbon atoms.

4. The disinfectant composition according to claim 3 , wherein the weight ratio of dimethyldialkyl ammonium compound to the alkyl dimethyl benzyl ammonium compound is between about 2:1 to about 1:1.

5. The disinfectant composition according to claim 4 , wherein the weight ratio of dimethyldialkyl ammonium compound to the alkyl dimethyl benzyl ammonium compound is about 1.5:1.

6. The disinfectant composition according to claim 5 , wherein the dimethyldiakyl ammonium compound is dimethyldioctyl ammonium chloride.

7. The disinfectant composition according to claim 2 , wherein the alkyl groups of the dimethyldialkyl ammonium compound are each octyl groups.

8. The disinfectant composition according to claim 7 , wherein the dimethyldialkyl ammonium compound is dimethyldioctyl ammonium chloride.

9. The disinfectant composition according to claim 2 , wherein the alkoxylated alcohol surfactant has between 4-6 moles of alkoxylation.

10. The disinfectant composition according to claim 2 , wherein the dimethyldiakyl ammonium compound is dimethyldioctyl ammonium chloride, the alkyl group of the alkyl dimethyl benzyl ammonium compound contains between 12 and 18 carbon atoms; the weight ratio of dimethyldialkyl ammonium compound to the alkyl dimethyl benzyl ammonium compound is about 1.5:1, wherein the alkoxylated alcohol surfactant has between 4-6 moles of alkoxylation.

11. The disinfectant composition according to claim 1 , wherein the sequestration agent is EDTA, and the pH adjuster is sodium citrate.

12. The disinfecting composition according to claim 1 , wherein of the disinfecting component (a) is present in a range of about 800 ppm to about 1600 ppm.
