Abstract

The present invention provides preferred, preferably liquid, hard surface cleaning compositions, compositions with cleaning liquid composition on a substrate, compositions used with absorbent pads and implements and devices for making the process of cleaning hard surfaces and/or maintaining their appearance and hygiene easier and more effective. These compositions, along with specific instructions for use are advantageous for removal of and/or prevention of buildup of soils commonly encountered on floors, glass surfaces, counters, walls, showers and/or tubs, said compositions comprising hydrophilic polymers to render the cleaned surface hydrophilic and to improve the appearance when the surface is either not rinsed, or when the composition is incompletely removed, specific surfactant, preferably surfactant selected to minimize spotting/filming, optionally specific organic cleaning solvents to provide cleaning and wetting particularly in applications where levels of non-volatiles need to be minimized, and, optionally, anti-bacterial agents for preserving or surface activity and optionally perfumes for aesthetics.

Claims

1. A pre-moistened cleaning wipe for cleaning a hard surface comprising:

at least one layer of fibrous substrate material impregnated with a cleaning composition, said composition comprising;

from about 0.005% by weight and about 0.5% by weight of said composition of a detergent surfactant wherein said detergent surfactant includes an alkylpolyglucoside;

an antimicrobial active wherein said antimicrobial active is selected from the group consisting of quaternary ammonium salts, clorhexidine diacetate, polyhexamethylene biguanide and mixtures thereof; and

from about 0.5% by weight and about 5% by weight of said composition of one, or more, organic cleaning solvents;

the balance being an aqueous solvent system, comprising water, wherein said composition has a pH under usage conditions of from about 2 to about 12.

2. The pre-moistened wipe of claim 1 wherein said detergent surfactant is at a level from about 0.02% to about 0.3% by weight of the cleaning composition.

3. The pre-moistened cleaning wipe of claim 1 wherein said cleaning composition does not include a hydrophilic polymer.

4. The premoistened wipe of claim 1 wherein said quatemary ammonium salts are selected from the group consisting of dioctyl dimethyl ammonium chloride, didecyl dimethyl ammonium chloride, C12, C14 and C16 dimethyl beazyl, and mixtures thereof.

5. The premoistened wipe of claim 4 wherein the antimicrobial actives provide residual disinfectancy.

6. The pre-moistened cleaning wipe of claim 1 wherein said antimicrobial active is at a level of between about 0.001% by weight to about 0.1% by weight of said composition.

7. The pre-moistened cleaning wipe of claim 1 wherein said at least one substrate layer is made of a fibrous material having a basis weight of between about 30 g/m² and about 100 g/m².

8. The pre-moistened cleaning wipe of claim 7 wherein said at least one layer is made of a fibrous material comprising between about 20% by weight and about 80% by weight of wood pulp fibers.

9. The pre-moistened cleaning wipe of claim 1 wherein said at least one layer is made of a fibrous material having a basis weight of between about 100 g/m² and about 500 g/m².

10. The pre-moistened cleaning wipe of claim 9 wherein said pre-moistened cleaning wipe has a wetness of between about 1 and about 5 grams of cleaning solution per gram of substrate.

11. The pre-moistened cleaning wipe of claim 1 wherein pre-moistened cleaning wipe has a fluid capacity of between about 2 and about 10 grams of liquid per gram of dry substrate.
