Abstract

An improved cleaning composition adapted to clean a variety of hard surfaces. The improved cleaning composition includes a cationic biocide that includes biguanide compounds and/or quats.

Claims

1. A hard surface cleaning wipe comprising:

a) a cleaning wipe comprising at least one layer of a nonwoven material; and

b) a hard surface cleaning composition loaded onto said nonwoven material comprising;

about 0.05-5 weight percent cationic biocide as the principal biocide, a cationic biocide release agent having an ionic strength in said cleaning composition of about 1×

10<sup>−

2</sup>-5 mol/l and constituting about 0.04-5 weight percent of said cleaning composition, about 0.01-5 weight percent surfactant, about 0.5 to less than about 5 weight percent organic solvent, and a majority weight percent water, wherein said hard surface cleaning composition is without a polymer and wherein said cationic biocide comprises a quaternary ammonium compound, said cationic biocide release agent comprises a salt selected from the group consisting of;

potassium citrate, sodium citrate, magnesium sulphate, sodium chloride, ammonium chloride, potassium chloride, and mixtures thereof, said surfactant comprises an alkyl polyglycoside, a majority of said organic solvent comprises a solvent selected from the group consisting of methanol, ethanol, n-propanol, isopropanol, butanol, pentanol, hexanol and mixtures thereof.

2. The hard surface cleaning wipe as defined in claim 1, wherein said solvent comprises at least two solvent compounds, one of said solvent compounds has a boiling point less than about 150°

C. and another solvent compound has a boiling point of at least about 150°

C.

3. The hard surface cleaning wipe as defined in claim 1, wherein said alkyl polyglycoside comprises a linear alkyl group.

4. The hard surface cleaning wipe as defined in claim 1, wherein said alkyl polyglycoside comprises an alkyl group having 6-22 carbons.

5. The hard surface cleaning wipe as defined in claim 1, wherein said quaternary ammonium compound comprises an alkyldimethylbenzylammonium quat.

6. The improved cleaning wipe as defined in claim 1, further comprising about 0.01-2% by weight of a builder.

7. The hard surface cleaning wipe as defined in claim 6, wherein said builder selected from the group consisting of:

sodium EDTA, disodium EDTA, potassium EDTA, dipotassium EDTA and mixtures thereof.

8. An improved cleaning wipe comprising:

I. a cleaning wipe comprising at least one layer of a nonwoven material; and

II. a cleaning composition loaded onto said nonwoven material comprising;

a. about 0.05-5% by weight of a cationic biocide,

b. about 0.03-10% by weight of a biocide release agent,

c. about 0.01-5% by weight of alkyl polyglycoside surfactant, and

d. at least about 0.05% by weight of solvent,

wherein said cleaning composition is without a polymer and wherein said solvent comprises at least two solvent compounds, one of said solvent compounds has a boiling point less than about 150°

C. and another solvent compound has a boiling point of at least about 150°

C., and the ratio of solvent having a boiling point less than about 150°

C. to the amount of solvent having a boiling point greater than or equal to about 150°

C. is between about 5;

1 and 1;

1.

9. The improved cleaning wipe as defined in claim 8, wherein the cleaning composition further comprises from about 0.01-2% by weight of a builder.

10. The improved cleaning wipe as defined in claim 9, wherein the cleaning composition further comprises a builder selected from the group consisting of:

sodium EDTA, disodium EDTA, potassium EDTA, dipotassium EDTA and mixtures thereof.
