Cleaning implements
View Patent ↗Disclosed herein is a cleaning article as an article of manufacture which includes a substrate onto which a cleaning composition is partially impregnated, leaving a portion of the substrate not impregnated with the composition. The impregnated part or side of the substrate is used to clean surfaces, especially vitro-ceramic surfaces while the unimpregnated part or side of the substrate is then used to dry and buff the cleaned surface.
1. A cleaning article having a sheet configuration comprising a flexible substrate having a first portion, divided by an impermeable barrier extending through the flexible substrate from a second portion, wherein the first portion contains a cleaning composition, and the second portion is essentially dry, wherein the cleaning composition comprises:
(a) 0.01-10% wt. of one or more surfactants selected from anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants and mixtures thereof;
(b) 2-40% wt. of a scouring agent selected from the group consisting of oxides, carbonates, quartzes, siliceous chalk, diatomaceous earth, colloidal silicon dioxide, alkali metasilicates, organic abrasive materials, abrasive water soluble salts, natural materials, nepheline syenite, talc and mixtures thereof;
(c) 0-10% wt. of a thickener;
(d) 0-10% wt. of one or more organic solvents;
(e) 0.01-7% wt. of an organopolysiloxane;
(f) 0-3% wt. of an acid;
(g) 0-5% wt. of one or more optional constituents;
(i) to 100% wt. of water,
wherein the barrier prevents migration of the cleaning composition from the first portion of the cleaning article to the second portion of the cleaning article.
2. The cleaning article of claim 1 wherein the cleaning composition comprises from 0.01-5% wt. of an organopolysiloxane.
3. The cleaning article of claim 1 wherein the cleaning composition comprises an acid.
4. The cleaning article according to claim 1 wherein the cleaning composition comprises both an anionic and a nonionic surfactant.
5. The cleaning article according to claim 1 wherein the cleaning composition comprises 2-35% wt. of a scouring agent.
6. The cleaning article according to claim 1 wherein the cleaning composition comprises 0.01-5% wt. of a thickener.
7. The cleaning article according to claim 1 wherein the cleaning composition comprises 0.01-7% wt. of an organic solvent.
8. A cleaning article according to claim 1 wherein the impermeable barrier is a heat sealed strip extending through the flexible substrate or is a layer or strip of a cured resin on the substrate.
9. A cleaning article according to claim 1 wherein the organic abrasive materials are selected from: polyolefins, polyethylenes, polypropylenes, polyesters, polystyrenes, acetonitrile-butadiene-styrene resins, melamines, polycarbonates, phenolic resins, epoxies and polyurethanes.
10. A cleaning article according to claim 1 wherein the natural materials are selected from rice hulls and corn cobs.
11. A method for the treatment of surfaces, particularly vitroceramic surfaces which method comprises the steps of:
providing a cleaning article according to claim 1 ;
applying the first portion of the cleaning article to a soiled surface, especially a vitroceramic surface;
manually spreading the cleaning composition and cleaning the soiled surface;
subsequently removing the first portion of the cleaning article from the surface,
applying the second portion of the cleaning article to the surface to manually buff the surface to provide a shined, cleaned appearance.
12. A cleaning article having a sheet configuration comprising a flexible substrate having a first portion, divided by an impermeable barrier extending through the flexible substrate from a second portion, wherein the first portion contains a cleaning composition, and the second portion is essentially dry, wherein the cleaning composition consists essentially of:
(a) 0.01-10% wt. of one or more surfactants selected from anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants and mixtures thereof;
(b) 2-40% wt. of a scouring agent selected from the group consisting of oxides, carbonates, quartzes, siliceous chalk, diatomaceous earth, colloidal silicon dioxide, alkali metasilicates, organic abrasive materials, abrasive water soluble salts, natural materials, nepheline syenite, talc and mixtures thereof;
(c) 0-10% wt. of a thickener;
(d) 0-10% wt. of one or more organic solvents;
(e) 0.01-7% wt. of an organopolysiloxane;
(f) 0-3% wt. of an acid;
(g) 0-5% wt. of one or more optional constituents;
(i) to 100% wt. of water,
wherein the barrier prevents migration of the cleaning composition from the first portion of the cleaning article to the second portion of the cleaning article.
13. The cleaning article of claim 12 wherein the organopolysiloxane is present in the cleaning composition in an amount from 0.01-5% wt.
14. The cleaning article of claim 12 wherein the acid is present in the cleaning composition.
15. The cleaning article according to claim 12 wherein the surfactant is a mixture of an anionic and a nonionic surfactant.
16. The cleaning article according to claim 12 wherein the scouring agent is present in the cleaning composition in an amount from 2-35% wt.
17. The cleaning article according to claim 12 wherein the thickener is present in the cleaning composition in an amount from 0.01-5% wt.
18. The cleaning article according to claim 12 wherein the organic solvent is present in the cleaning composition in an amount from 0.01-7% wt.
19. A cleaning article according to claim 12 wherein the impermeable barrier is a heat sealed strip extending through the flexible substrate or is a layer or strip of a cured resin on the substrate.
20. A cleaning article according to claim 12 wherein the organic abrasive materials are selected from: polyolefins, polyethylenes, polypropylenes, polyesters, polystyrenes, acetonitrile-butadiene-styrene resins, melainines, polycarbonates, phenolic resins, epoxies and polyurcthanes.
21. A cleaning article according to claim 12 wherein the natural materials are selected from rice hulls and corn cobs.
22. A method for the treatment of surfaces, particularly vitroceramic surfaces which method comprises the steps of:
providing a cleaning article according to claim 12 ;
applying the first portion of the cleaning article to a soiled surface, especially a vitroceramic surface;
manually spreading the cleaning composition and cleaning the soiled surface;
subsequently removing the first portion of the cleaning article from the surface, applying the second portion of the cleaning article to the surface to manually buff the surface to provide a shined, cleaned appearance.
