Abstract

Articles for cleaning debris from a hard surface are described herein, the articles include a hard surface cleaning composition which includes from about 0.1% to about 50% by weight of the composition of a detergent surfactant and a pad including a core and adapted to contact the hard surface. The core comprising up to about 50% cellulosic material. They are high sudsing, have excellent soap scum removal and hard water deposit removal properties and are easy to rinse. A sprayer, methods of use and kits are also disclosed.

First claim

What is claimed is:

1. An article for cleaning debris from a hard surface, said article comprising:
a) a hard surface cleaning composition which comprises from about 0.1% to about 50% by weight of the composition of a surfactant wherein the surfactant is an alkyl sulfate detergent surfactant, the alkyl group of the alkyl sulfate detergent surfactant contains 8 carbon atoms on the average with substantially all of the alkyl groups having within two carbon atoms of the 8 average carbon atoms, wherein the cleaning composition does not include an alkyl sulfate detergent surfactant that contains about 10 carbon atoms on the average, with substantially all of the alkyl groups having within two carbon atoms of the 10 average carbon atoms, wherein the cleaning composition has a suds dissolution rate from about 0.8 ml/s to about 2.6 ml/s using the Suds Dissolution Rate Test and
b) a pad comprising a core and adapted to contact the hard surface, the core comprising up to about 50% cellulosic material.

2. An article according to claim 1 , wherein the core comprises up to about 30% cellulosic material.

3. An article according to claim 1 , wherein the core is free of cellulosic material.

4. An article according to claim 1 , wherein suds are generated in under about 50 strokes using the Suds Generation Value Test.

5. An article according to claim 1 , wherein the cleaning composition has a particle size distribution at Dv50 of at least about 200 μm using the Particle Size Distribution Test Method.

6. An article according to claim 1 , further comprising from about 0.25% to about 4% by weight of the composition of an anionic cosurfactant selected from the group consisting of: C 12 -C 18 paraffin sulfonates, C 8 -C 18 alkyl ethoxy sulfates; C 8 -C 18 alkyl sulfates, and mixtures thereof.

7. An article, for cleaning debris from a hard surface, said article comprising:
a) a hard surface cleaning composition which comprises from about 0.1% to about 50% by weight of the composition of a surfactant wherein the surfactant is an alkyl sulfate detergent surfactant, the alkyl group of the alkyl sulfate detergent surfactant contains 8 carbon atoms on the average with substantially all of the alkyl groups having within two carbon atoms of the 8 average carbon atoms, wherein the cleaning composition does not include an alkyl sulfate detergent surfactant that contains about 10 carbon atoms on the average, with substantially all of the alkyl groups having within two carbon atoms of the 10 average carbon atoms, wherein the composition further comprises from about 0.001% to about 0.3% by weight of the composition of a hydrophilic polymer selected from the group consisting of: polystyrene sulfonate; polyvinylpyrrolidone; polyvinyl pyrrolidone/acrylate copolymer; polyvinyl pyridine; polyvinyl pyridine n-oxide; and mixtures thereof, wherein the cleaning composition has a suds dissolution rate from about 0.8 ml/s to about 2.6 ml/s using the Suds Dissolution Rate Test; and
b) a pad comprising a core and adapted to contact the hard surface, the core comprising up to about 50% cellulosic material.

8. An article according to claim 1 , comprising from about 1% to about 10% by weight of the composition of said alkyl sulfate surfactant; from about 1% to about 6% by weight of the composition of one, or more, organic cleaning solvents; from about 2% to about 6% by weight of the composition of organic acid; from about 60% to about 90% by weight of the composition of an aqueous solvent system, said composition having a pH of about 3 to about 7.

9. An article according to claim 1 , further comprising an organic cleaning solvent selected from the group consisting of dipropylene glycol n-butyl ether, butoxy propanol and propoxy propanol.

10. An article according to claim 1 , further comprising a polycarboxylic acid selected from the group consisting of: citric acid and mixtures of succinic, adipic, glycolic, and glutaric acids, and mixtures thereof.

11. An article according to claim 1 , further comprising a dispenser containing the cleaning composition, wherein the dispenser comprises a trigger spray device or an aerosol device.

12. An article according to claim 11 wherein the dispenser is an aerosol device and is capable of providing droplets with a particle size distribution at Dv50 of at least about 200 μm using the Particle Size Distribution Test Method.

13. An article according to claim 1 wherein the cleaning composition has a pH under usage conditions of from about 2 to about 7.

14. A kit for cleaning a hard surface, comprising the article according to claim 1 .

15. A process of cleaning a surface comprising:
applying an effective amount of a cleaning composition according to claim 1 to the surface and
wiping the surface with a pad comprising a core and adapted to contact the hard surface, the core comprising up to about 50% cellulosic material.

16. The process of claim 15 wherein the effective amount is applied onto said surface using a trigger-spray device or an aerosol device.
