Abstract
1. A ready-for use composition for cleaning hard surfaces and containing a scouring base impregnated with a cleaning liquid, characterised by an expanded paper as scouring base which is in the form of a sheet of paper cut along parallel lines, close to one another, by means of short cuts repeated along each line and closely spaced, with lateral staggering of the cuts from one line to the next, and which is expanded by a stretching of the paper at right angles to the cut lines.
Description
The present invention relates to ready-for-use compositions intended for cleaning hard surfaces and containing a scouring base impregnated with cleaning liquid, which consists of a sheet of latticed and expanded paper.
It has been known for a very long time to clean glass, porcelain, ceramic, marble, metals and other hard surfaces using abrasive powders, but the application of these powders requires the addition of water and the use of a rag or a sponge. Liquids are also known which contain cleaning agents in solution and scouring agents in suspension; this technology is very fully described in EJS-A-2,164,810, 2,196,992, 2,275,049, 2,739,129, 2,892,795, 2,920,045, 3,281,367 and ' 3,681,122, BE-A-737,033, GB-A-1,303,810, 1,308,190 and 1,345,119, CA-A-578,717, 635,321, 685,394 and 843,388 and FR-A-1,548,948, 2,161,963, 2,256,952, 2,283,952, 2,349,648, 2,349,649, 2,356,719, 2,383,229 and 2,405,990.
Scouring liquids represent a real advance, but their application still requires a rag or a sponge.
Products exist which comprise a scouring pad impregnated with a detergent composition such as a soap. Finally, a cloth impregnated with a cleansing agent for cleaning dishes, which cloth consists of two paper layers and one intermediate layer comprising a net made of elastic thermoplastic resin, said layers being stuck to each other, is known from FR-A-1 363 974. These products require water at the time of use and are not suitable for all purposes because for instance the scouring pad consists of wire, which can cause irreparable damage to non-metallic surfaces by scratching them.
It has now been found that all these disadvantages can be eliminated by the use of a ready-to-use product which requires neither water nor rags or a sponge and with which there is no danger of scratching the cleaned surfaces. A product of this type is presented by the claimed composition for cleaning hard surfaces containing a scouring base impregnated with a cleaning liquid which is in the form of a sheet of an expanded paper cut along parallel lines, close to one another, by means of short cuts repeated along each line and closely spaced, with lateral staggering of the cuts from one line to the next, and which is expanded by a stretching of the paper at right angles to the cut lines. This gives a more or less transparent lattice, the structure of which varies as a function of the thickness and the nature of the paper, the length and the spacing of the cuts, and the distance between the lines. By virtue of the oblique shape adopted by the strips surrounding the meshes of the lattice, an expanded paper of this type, impregnated with a cleaning liquid, possesses more or less pronounced scouring properties depending on the nature and the thickness of the paper. Conveniently, the lateral staggering is substantially equal to half the sum obtained by adding the length of a cut and the space separating two adjacent cuts on one and the same line.
The cleaning liquid is chosen from the group comprising aqueous solutions of detergent and organic solvents, which, if desired, can contain an adjuvant chosen from the group comprising thickeners, colorants, fluorescent brighteners, alkalis, antiseptics, humectants, water repellents, perfumes and antistatic agents.
The chacateristics of the sheet of expanded paper are not critical.
The paper can be made, in particular, from a pulp of chemical and/or mechanical origin, containing cellulosic fibres derived from wood, cotton, alfa, flax, cereals, old rags and/or waste paper; it can also be made from, or contain, fibres of wool, silk, glass, rock and polymeric materials, for example those based on polyalkylenes polyalkadienes, polystyrenes, polyacrylic acid esters, polymethacrylic acid esters, polyesters, polyurethanes, polyamides, 4polyvinyl alkanoates and/or polyvinyl halides; it can contain fillers for modifying its structure (density, abrasiveness, permeability and mechanical strength), these fillers being chosen, for example, from the group comprising gums, gelatins, resins, industrial starches, pigments and insoluble mineral powders such as silica, metal silicates, metal phosphates, metal carbonates, barium sulfate, calcium sulfate, titanium oxide, kaolin, kieselguhr, tin oxide, perlite and cristobalite.
The thickness of the paper can vary within limits compatible with the use in question, i.q. permitting a sufficient flexibility an The space between two adjacent cuts along one and the same line is preferably between 1 and 4 millimetres; even more preferably, this space is between 2 and 3 millimetres.
The distance between two adjacent lines of cuts is preferably between 0.5 and 3 millimetres; even more preferably, this distance is between 0.7 and 1.5 millimetres.
The dimensions of the sheet of paper are not critical and depend on the use for which it is intended; for domestic use or for cleaning small pieces, it is possible, for example, to cut the sheet to dimensions containing between 1 and 10 square decimetres, whereas for industrial use, the sheet can be produced with large dimensions of several tens of square decimetres,or even in the form of long, folded or rolled strips arranged in a box serving as a dispenser.
The expanded paper can be present in the composition either in its stretched form or in its unstretched form, in which case the stretching is carried out by the user at the time of use.
If the cleaning liquid contains water, the origin of the water is generally not critical; it can be spring water, rain water, river water, softened water, demineralised water or distilled water. It is generally preferred to use water containing relatively small proportions of calcium carbonate and magnesium carbonate.
The surfactants which can be used according to the invention can be chosen from the group comprising all the known anionic, cationic, amphoteric or non-ionic surfactants. Representative surfactants are described in McCutcheon's Detergents and Emulsifiers 1969 Annual, in which these compounds are indexed according to their chemical formula and their tradename. Other suitable surfactants are described in Surface Active Agents and Detergents, Volume II, by Schwartz, Perry and Berch (Interscience Publishers, 1958).
Examples of suitable anionic surfactants are soaps and also synthetic, sulfated and sulfonated surfactants, in particular anionic surfactants having about 8 to 26, and preferably about 10 to 22, carbon atoms per molecule. The soaps are generally the water-soluble, alkali metal or ammonium soaps of fatty acids each containing 10 to 18 carbon atoms, and mixtures thereof.
The sulfated and sulfonated surfactants are also known in the art and can be prepared from suitable organic materials which can be sulfonated (i.e. which can be subjected to true sulfonation and/or sulfation).
Amongst the wide variety of suitable sulfates and sulfonates, it is preferable to use the aliphatic sulfates and sulfonates having about 8 to 22 carbon atoms and also the alkylaromatic sulfonates containing about 8 to 22 carbon atoms in the alkyl group, and preferably 12 to 18 carbon atoms.
The detergent alkylaromatic sulfonates in question can have a mononuclear or polynuclear structure.
More particularly, the aromatic nucleus can be 82361 derived from benzene, toluene, xylene, phenol, cresols, phenol ethers, naphthalene or phenanthrene derivatives.
The alkyl group can vary in a similar manner. Thus, for example, the alkyl groups can have a linear or branched chain (the linear chains being very much preferred) and can be, for example, dodecyl, tridecyl, pentadecyl, octyl, nonyl, decyl or undecyl radicals, mixed alkyls derived from fatty products, olefins consisting of cracked paraffin wax or polymers of lower monoolefins.
Although the number of sulfonic acid groups present on the nucleus is not critical, it is preferable for only one of these groups to be present, so as to preserve as far as possible an equilibrium between the hydrophilic and hydrophobic parts of the molecule and to obtain an effec15 tive surface activity.
Other particular examples of suitable surface-active alkylaromatic sulfonates are linear alkylbenzenesulfonates in which the alkyl group contains, for example, between 10 and 18 carbon atoms, more particularly between 10 and 15 2o carbon atoms on average; these include sodium dodecylbenzenesulfonate, sodium tridecylbenzenesulfonate and sodium (higher)alkylbenzenesulfonates in which the alkyl contains between 10 and 15 carbon atoms, i.e. on average 12.5 carbon atoms, per molecule.
Other suitable surfactants are sulfated or sulfonated, surface-active aliphatic compounds preferably having 12 to 22 carbon atoms. The following correspond to this definition: sulfuric acid esters of polyalcohols incompletely esterified by higher fatty acids, such as coconut 3o oil monoglyceride monosulfate and tallow glyceride monosulfate, pure or mixed, long-chain alkyl sulfates such as lauryl sulfate and cetyl sulfate, esters of hydroxysulfonated higher fatty acids, such as higher fatty acid esters of low molecular weight alkylolsulfonic acids, like fatty acid esters of isethlonic acid, sulfates of fatty acid ethanolamides of aminoalkylsulfonic acids, such as the laurylamide. of taurine, or olefinsulfonates and paraffinsulfonates.
More particularly, it is preferable to use sulfated aliphatic compounds containing at least about 8 carbon atoms, in particular those containing about 12 to 18 or 22 carbon atoms per molecule. In addition to or instead of the surface-active, aliphatic and aromatic sulfates and sulfonates, it is also possible to use the corresponding organic phosphates and phosphonates if the presence of such organophosphorus compounds is permitted by the national regulations.
As cationic surfactants, it is also possible to use long-chain quaternary alkylammonium compounds such as quaternary cetylammonium salts. This group includes cetyltrimethylammonium chloride and cetylpyridinium chloride. Diethylaminoethyloleylamide is another compound which can also be used.
The non-ionic surfactants comprise, for example, polyoxyethylene ethers of hydroxylated alkylaromatic compounds (such as polyoxyethyleneated alkylphenols), polyoxyethylene ethers of long-chain aliphatic alcohols, polyoxyethylene ethers of hydrophobic propylene oxide polymers, and also (higher)alkylamine oxides such as lauryldimethylamine oxide and 3-lauroylamido-propyldimethylamine oxide.
According to the invention, it is also possible to use amphoteric surfactants, for example salts of (higher)alkyl-beta-aminopropionic acids, the sodium salt of Nlauryl-beta-alanine, betaines substituted by higher alkyl groups, lauryldimethylammonium-acetic acid and also compounds of the imidazoline type, such as the disodium salt of 1-(2-hydroxyethyl)-l-carboxymethyl-2-hendecyl-4,5-dihydroimidazolinium hydroxide.
The anionic and cationic surfactants are commonly used in uhe form of their water-soluble salts. As regards the synthetic anionic compounds, the alkali metal salts (for example sodium and potassium salts) are preferable, although it is possible, if desired, to use other salts, for example ammonium salts, (lower)alkylamine salts (i.e. salts of monoalkylamines and trialkylamines containing to 4 carbon atoms in the alkyl group, such as methylamine, diisopropylamine and tributylamine), lower alkanolamine salts (for example salts of ethanolamine, diethanolamine, triethanolamine and isopropanolamine) and also alkaline 5 earth metal salts and salts of similar metals such as calcium and magnesium. As regards the cationic surfactants, they can contain an anion such as chloride, sulfate or acetate. Preferably, if it exists, the surfactant is present in the cleaning liquid in a proportion of between 0.1 Iq and 25 per cent by weight. If at least one is present in the cleaning liquid, the organic solvent or solvents are chosen from the group comprising the non-caustic organic liquids known to those skilled in the art for their solvent power. Solvents of this type are described, in particu15 lar, in Solvents Guide by MARSDEN & MANN.

The alcoholic solvents include, in particular, alkanols, cycloalkanols, aralkanols and alkanediols, for example methanol, ethanol, propanol, isopropanol, butanol, isobutanol, sec.-butanol, tert.-butanol, isoper.tanol, cyclo25 hexanol, methylcyclohexanols, benzyl alcohol, ethylene glycol, propylene glycol, butylene glycol and propane-1,3-diol, and mixtures thereof.
