Definitions

• the present invention relates to compositions for the treatment of hard surfaces, such as floors, which are effective to clean, polish and protect such surfaces, and particularly to compositions comprised of an acid/silicone base formulation.
• the present invention relates to the treatment and maintenance by a single product of floors, walls, stairs, patios, walkways and other hard and substantially smooth surfaces for the purposes of cleaning, polishing and protecting them from wear and weathering.
• the present invention may be broadly applied to a variety of surfaces; however, the term "floor” will be utilized hereinafter for convenience in collectively referring to all appropriate surfaces.
• the present invention relates particularly to a product for treating and maintaining floors and more particularly to a product for treating and maintaining floors having a surface material which is hard and smooth.
• Representative floor surfaces include those made of metal such as steel, or stone such as natural or reconstituted marble, ceramics such as terracotta, as well as surfaces bearing an organic-based coating such as plastic sheets or acrylic tile, and even to surfaces covered with wood parquet. Fibrous materials, however, such as carpets and rough surfaces such as concrete are not hard and substantially smooth as contemplated herein, and are therefore inappropriate surfaces for treatment with the products of the present invention.
• the traditional approach to floor treatment involves a multi-step procedure.
• Floors are initially exposed to a protecting agent which forms an interface between the floor and the air or objects which pass over or rest upon the surface.
• the protective interface will also impart an acceptable shine to the floor.
• Subsequent "maintenance" steps involve the cleaning, polishing and continued protecting of the treated floor.
• the basic treatment traditionally involves the production of a chemical reaction, commonly called crystallization, which leads to the formation of a hard, shiny superficial layer on the marble surface (i.e. , calcium carbonate or CaCo3).
• This reaction occurs according to the known reaction scheme: SiMgF6 + 2CaCO3 ⁇ SiO2MgF2 + 2F2Ca + 2CO2.
• SiNa2F6 can be used in place of SiMgF6.
• the basic treatment consists of the application of a varnish or film-forming compound.
• the ultimately-desired shining appearance then results from a polymerization of the treatment product itself without the necessity for chemical reaction with the floor surface.
• an acrylic-based layer can be formed for protection purposes.
• maintenance consists of a cleaning or scouring step, followed by the reapplication of a shiny and/or protective layer and subsequent polishing thereof.
• Future maintenance of a treated floor thus provides maintenance and/or restoration of the foregoing protective layer, unless the residuum of the floor treatment product is stripped down to the actual floor surface, as may periodically be necessary or desirable.
• the traditional maintenance scheme involves a "spray” step which involves spraying, onto the surface to be treated, an appropriate composition followed by the mechanical actions of brushing or polishing, advantageously accomplished with the aid of a floor polishing machine.
• the present invention relates to compositions which exhibit a polyvalent action in the sense that they are useful for the treatment of all surfaces, such as floors, having a hard and substantially smooth surface regardless of the compositional nature of such surfaces.
• the present invention further relates to products which accomplish protecting through chemical reaction or otherwise, cleaning, polishing and maintaining in one step.
• Such products may include, for example, a cleaning ingredient such as an acid mixed together with a silicone capable of imparting water repellancy as well as an enhanced shine to the floor surface so treated.
• a cleaning ingredient such as an acid mixed together with a silicone capable of imparting water repellancy as well as an enhanced shine to the floor surface so treated.
• the complete compositions formulated from such a base may be critical, however, as they will vary in substrate specificity, efficacy, odor and even in flammability.
• U.S. Patent No. 3,681,122 to Domicone et al. and Canadian Patent No. 843,388 to Hyde disclose abrasive silicone-­containing cleaning and conditioning compositions. While these compositions are effective for cleaning and conditioning glass-­ceramic surfaces, they have certain unsatisfactory properties for more broad-based applications.
• compositions when the compositions contain a soluble alkaline metal silicate they are useful for cleaning glass-ceramic surfaces which have been stained, but the surface maintains and develops a stubborn stain over a period of time from the treatment product. If an analogous composition is utilized which is free of the soluble alkaline metal silicate, it is effective for protecting the glass-ceramic surface without causing further stain but it also lacks the cleaning power to remove the old stain.
• U.S. Patent No. 3,579,540 to Ohlhausen relates to a method for treating nonporous substrates with acid/silicone products to protect and render them water repellant.
• the compositions therein disclosed comprise a mineral acid such as sulfuric acid, phosphoric acid, aromatic sulfonic acids, aliphatic sulfonic acids and hydrochloric acid.
• the silicone reagent disclosed by Ohlhausen also includes an alkylpolysiloxane such as dimethylpolysiloxane, methylhydrogenpolysiloxane and methylphenylpolysiloxane.
• Solvents, diluents and extenders such as alcohols, chlorinated hydrocarbons, ethers, ketones, esters, aromatic hydrocarbons, water, colloidal pyrogenic silicas and clays are also disclosed as additional ingredients.
• Such formulations are relatively limited in their applicability in the absence of the ability to form protective layers through mineral reacting components or acrylic copolymers, and in the absence of additional emulsifying agents.
• pure organic acids possess advantageous cleansing activities.
• U.S. Patent No. 4,212,759 to Young et al. discloses an acidic cleaning composition comprising an acid-stable hydrocarbon-and-water emulsion which contains a liquid hydrocarbon, a solid porous absorbent, and a minor amount of an acid to provide an acidic emulsion.
• the formulation may also contain a soap or detergent, and a minor amount of a polysilicone or a thickening agent.
• Preferred acids include oxalic acid, sulfamic acid and the like.
• compositions disclosed may also include a porous absorbent present in an amount sufficient to stabilize the emulsion, and which may also enhance the cleaning activity of the compositions disclosed by acting as an abrasive.
• Such formulations act primarily as a cleaning or maintaining agent rather than a protecting agent in the absence, for example, of mineral-reacting components and acrylic copolymers. The use of an acid only to form an acidic emulsion does not appear to provide the cleansing efficacy of other acid cleaners.
• U.S. Patent No. 4,124,523 to Johnson discloses silicone-­containing acidic cleaners which consist essentially of polydimethylsiloxane, water, acid, abrasive and colloidal silica flocculated with a nonionic surfactant.
• the particular acid components are said not to be critical and may include oxalic acid, phosphoric acid, acetic acid, citric acid and hydrochloric acid.
• Suitable silicone components include methyl-endblocked, hydroxyl-endblocked and methyl-and hydroxyl-endblocked poly­dimethylsiloxanes and mixtures thereof, and the polydimethyl­siloxane fluid may be present in the form of an emulsion.
• a suspending agent or emulsifier may be used to properly disperse the polydimethylsiloxane fluid in the aqueous phase.
• Johnson also discloses that any of the well-known nonionic surfactants may be used in the compositions taught.
• the compositions disclosed may also include an abrasive such as diatomaceous earth, aluminum oxide, ground quartz, tripoli and talc. Again, such formulations are primarily cleaners rather than protecting treatments.
• U.S. Patent No. 3,095,381 to Tinnon et al. discloses a hard surface cleaning composition containing an alkyl-substituted tertiary acetylenic hexynol which additionally contains an organic solvent, isopropyl and diethylene glycol monoethyl ether, as well as non-volatile surfactants.
• U.S. Patent No. 4,689,168 to Requejo discloses a hard surface cleaning composition comprising an organic polar solvent, a volatile organosiloxane and a volatile surfactant such as an acetylenic alcohol or diol. An acidic component is not taught by Requejo.
• U.S. Patent No. 3,992,235 to Denissenko et al. relates to a composition capable of shining the surface of a substrate such as a wood parquet floor without prior stripping and without subsequent polishing, by simply applying and drying the composition on the surface.
• the composition is an anhydrous solution comprising at least six and preferably seven constituents which consist, in critical proportions, of a solid film-forming macromolecular compound, a hard resin, a liquid plasticizer, a solid plasticizer and a solvent mixture consisting of at least one lower alkanol.
• the seventh, optional component may be a silicone oil.
• Certain cleaning acids may also be undesirable in particular formulations, as explained in U.S. Patent No. 4,013,579 to Nakasone et al. which discloses an acidic cleaning composition comprising at least one member selected from the group consisting of furan-carboxylic acid and derivatives thereof and tetrahydrofuran-carboxylic acid and derivatives thereof.
• Nakasone et al. teaches that a variety of acid substances are effective cleaning agents, including oxalic acid, but teaches that such substances have significant toxicity and/or smell disadvantages. It was therefore a primary object of the composition disclosed by Nakasone et al. to provide an acidic cleaning composition in which the disadvantages of conventional acidic cleaners are greatly reduced.
• this patent teaches that oxalic acid, while an effective spot remover, has a very high toxicity and a high skin penetrating property and therefore that the use of oxalic acid-containing compositions is undesirable. Notwithstanding the teachings of Nakasone et al., the use of acidic components such as oxalic acid is generally considered to be desirable by those skilled in the art for their superior cleansing efficacies.
• What is desirable in a floor treatment product is a formulation applicable to a wide variety of floor surfaces which, furthermore, protects and maintains in a single formulation and which also falls within acceptable limits on corrosivity, flammability, odor and slipperiness. It is thus an object of the present invention to provide a complete floor treatment composition which is polyvalent in the sense that it possesses a broad applicability to a variety of surface compositions. It is a further object of the present invention to provide a floor treatment composition that is advantageously formulated for its efficacy, acceptable odor and compliance with U.S. flammability regulations and other safety considerations.
• an object of the present invention is a floor treatment composition which protects both calcium carbonate-containing as well as nonmineralized floors; effectively cleans hydrophilic as well as hydrophobic dirt and stains and imparts a shine to a surface, all in one solution. Additionally, the composition is acceptable for daily or routine maintenance and avoids the need for separate stripping and polishing products.
• the present invention which, per gallon formulated (or about 3,776 ml), forms an emulsion which comprises the following ingredients: a polycarboxylic chelating acid, a plurality of silicones including at least one aminofunctional polysiloxane and preferably at least one silane, an alkaline earth fluorosilicate and an acrylic resin; a co-solvent system which includes at least one lower aliphatic alcohol, glycol ether, halogenated hydrocarbon and nonhalogenated hydrocarbon solvent, and water; and as additives, preferably, a perfuming agent, a surfactant and an emulsion stabilizer.

• Michemlube 743 a paraffin emulsion sold by Michelman, Inc. which acts as a stabilizer
• Michemlube 743 is added to enhance the shine of the floor and as a fixative for the emulsion previously formed.
• the balanced compositions of the present invention generally include at least one, and optionally a plurality of, acidic cleaning agents, such as the polycarboxylic chelating acids. Additionally, the compositions include a plurality of silicones further including at least one aminofunctional polysiloxane and at least one silane which is believed to act as a cross-linking agent. The plurality of silicones should reflect different molecular weights and therefore different molecular sizes, so as to most effectively coat or fill the variously-sized cracks and depressions of the floor to be treated.
• An alkaline earth fluorosilicate is included to react chemically with mineralized or mineral-containing floors such as marble or vinyl composite floors, respectively.
• a film-forming agent such as an acrylic resin is included to form a protective layer above the surface treated.
• a co-solvent system is also co-formulated, including at least one lower aliphatic alcohol, at least one glycol ether, at least one halogenated hydrocarbon, at least one nonhalogenated hydrocarbon solvent and water.
• the glycol ether serves to help solubilize the silicone components of the formulation, as well as to clean the floor surface.
• co-formulated as additives are orange oil terpene which imparts a desirable odor to the ultimate composition, a surfactant and a stabilizing agent like Parrafin Emulsion (Michemlube 743 such as is sold by the Michelman Corp. of Cincinnatti, Ohio) which is added to stabilize the emulsified product of the preceding ingredients.

It is contemplated that for particular floors, such as marble, the acid component may be omitted to avoid a bleaching effect. The proper amount of whichever acid is chosen can be adjusted to suit a particular floor surface by routine testing.
• the contemplated silicones include organic polysiloxanes which are film formers having a viscosity in the range of about 5 to about 50,000 centistokes, preferably about 100 to about 10,000 centistokes.
