Abstract

A two-part disinfecting systems, as well as disinfecting compositions and methods for making and using the same. The two-part disinfecting system contains a first part and a second part adapted to be mixed to yield an aqueous disinfecting composition, wherein the first part comprises a chlorite and the second part comprises an acid, and wherein the first part, the second part, or both the first and second parts comprise an olefin compound.

Claims (19)

1. A two-part disinfecting system comprising a first part and a second part adapted to be mixed to yield an aqueous disinfecting composition,

wherein the first part comprises a chlorite and the second part comprises an acid, and wherein the first part contains an olefin compound having the formula:

CH 3 (CH 2 ) 7 CH═CH(CH 2 ) 7 (CO)NCH 3 CH 2 CH 2 SO 3 Na

wherein the olefin compound is present in the first part so that, when the first part and second part are combined, the olefin compound is present within the disinfecting composition at a concentration ranging from about 0.005% to about 50% by weight, and wherein the acid is present in the second part in an amount so that, when combined with the first part, the pH of the disinfecting composition is between about 2 and about 5.

2. The system of claim 1 , further comprising an oxidizable colorant present in the first part, the second part, or both the first part and second part.

3. The system of claim 1 , wherein the olefin compound is present in the second part in an amount so that, when the first part and second part are combined, it is present within the disinfecting composition at a concentration ranging from 0.05% to 10% by weight.

4. The system of claim 1 , wherein the chlorite is a metal chlorite.

5. The system of claim 4 , wherein the metal chlorite is an alkali or alkaline earth metal chlorite.

6. The system of claim 5 , wherein the metal chlorite is sodium chlorite or potassium chlorite.

7. The system of claim 1 , wherein the chlorite is present in the first part in an amount so that, when combined with the second part, it is present within the disinfecting composition at a concentration ranging from about 0.005% to about 3% by weight.

8. The system of claim 1 , wherein the acid is lactic acid.

9. The system of claim 1 , wherein the acid is present in the second part in an amount so that, when combined with the first part, it is present within the disinfecting composition at a concentration ranging from about 0.05% to about 10% by weight.

10. The system of claim 2 , wherein the oxidizable colorant is a food, drug and cosmetic colorant.

11. The system of claim 1 , wherein the acid has a pK a ranging from 2 to 5.

12. The system of claim 1 , wherein the acid is an organic acid, an inorganic acid, and mixtures thereof.

13. The system of claim 1 , wherein the organic acid is glycolic acid, lactic acid, malic acid, mandelic acid, citric acid, tartaric acid, adipic acid, succinic acid, malonic acid, heptanoic acid, octanoic acid, nonanoic acid, benzoic acid, gluconic acid, or a mixture thereof.

14. The system of claim 1 , wherein the inorganic acid is sulfuric acid, sulfamic acid, phosphoric acid, hydrochloric acid, nitric acid, or a mixture thereof.

15. The system of claim 1 , wherein both the first part and the second part are independently in the form of an aqueous solution, emulsion, microemulsion, cream or gel.

16. The system of claim 1 , wherein the first part, the second part, or both the first and second parts further comprise a textural modifier, wetting agent, thickening agent, skin conditioner, healing agent, film-forming polymer, surfactant, preservative, or a mixture thereof.
