Definitions

  • Silica is the primary raw material used in the manufacture of window glass, mirror surfaces, glass furniture surfaces, and the like. Such surfaces are consistent, hard and nonporous. Various kinds of soil commonly become attached to such surfaces, including environmental pollutants, airborn cooking fat, bird excreta, cosmetic splatter, fingerprints, and the like.
  • window cleaning products depend for their effectiveness on the user's rubbing a film of an aqueous solution or emulsion over the soiled glass.
  • the detergents or surfactants employed in these products may contribute somewhat to the cleaning process by aiding the dispersion of greasy dirt, the main cleaning effect is due to the physical removal of the dirt from the glass by the moving towel, sponge or cloth.
  • the amount of user effort needed to effectively clean a glass surface is compounded due to the fact that the transparent liquid films of cleanser which are deposited give no clear indication of the extent to which the glass has been coated or cleaned.
  • Glass Wax ® Gold Seal Co., Bismark, N.D.
  • a cloth moistened with Glass Wax leaves a cloudy film or haze on the glass surface after it has been rubbed over the glass and allowed to dry. This film both permits the user to check for complete coverage and then to insure that all of the surface has been wiped clean of both cleaner particles and of soil.
  • Glass Wax is water-based, and the weight of the water phase adds to the cost of shipping and storage. Also, the product must be formulated so as to insure the stability of the dispersed solid phase until the product is used. The large ratio of water to solid also requires the user to wait until the wetted glass has substantially dried before wiping it clean.
  • an object of the present invention to provide a product which minimizes the effort required to clean a glass surface.
  • a dry cleaner in the form of a flexible substrate base which is impregnated with fine particles of a water-insoluble diatomaceous earth and with a small amount of synthetic organic detergent and/or particles of a smectite clay.
  • the base which may be in the form of a porous sheet, is wetted and wiped over a glass, ceramic, or other nonporous surface, the water insoluble material is physically transferred to the glass surface where it mixes with the soil to leave a thin, visible film or haze. The film or haze, either in the dry, partially dry, or wet state, is then wiped off the window with an uncoated paper or cloth towel.
  • the cleaners of the present invention are prepared by impregnating a flexible, porous substrate base with an aqueous dispersion of fine particles of diatomaceous earth in combination with at least one of a dispersing agent and smectite clay particles.
  • a dispersing agent and clay particles will be employed in combination with the diatomaceous earth to impregnate a base sheet.
  • the water is then evaporated from the impregnated base to leave the solid particles of diatomaceous earth, and the clay particles and/or the detergent, evenly distributed throughout the interstices and on the surface of the substantially dry sheet.
  • the clay particles and/or dispersing agent function to help adhere the film of soil and diatomaceous earth to the glass surface and also to enhance the cleaning power of the cleaners by aiding the dispersion of the soil particles so as to form the opaque film.
  • the size of the particles which form the solid phase of the dispersions used to impregnate the base sheets are selected so as to be fine enough to penetrate the interstices of the base sheet and to leave a coherent, opaque film when the cleaner is wiped across the glass surface.
  • the particles must also be water-insoluble, wettable and inert to the surfaces sought to be cleaned.
  • processed high-bulk diatomaceous silicas are preferred.
  • a particularly preferred silica product for use in the present invention is Snow Floss® (Manville Gorp., Denver, Col.), which has a surface area of 20-30 sq. m./g, will absorb about 190% of its weight of oil, and has a 325 mesh residue of 0.3% .
  • silica product which may be used alone or in combination with other silicas is the silaceous diatomaceous earth Celatom MN-23 ® (Eagle Picher, Cincinatti, Ohio), which has a 325 mesh residue of 0-3% and a median particle diameter of 2.0 microns.
  • diatomaceous earths When used in combination with other solids, diatomaceous earths will preferably make up about 50-80% of the total solids used, most preferably 65-75%.
  • Particulate clays useful as optional components in the cleaners of the present invention inc lude the wettable smectite clays generally disclosed in U.S. Pat. No. 4,062,647, the disclosure of which is incorporated by reference herein.
  • Particularly useful clays are those of the bentonite class, such as Volclay ® (344 Bentonite, Whittaker, Clark & Daniels, Inc., S. Plainfield, N.J.) which has 96% of its particles sized less than 44 microns and comprises about 58-64% silica and 18-21% alumina. Volclay has a 20 mesh residue of 10%.
  • clay particles will preferably comprise about 5-45% of the total solids used, most preferably about 25-35%.
  • the solid particles are stirred into an excess of water to form the aqueous dispersions used to impregnate the base sheets.
  • These dispersions may be formulated to comprise about 3-35%, preferably 5-25%, of at least one, and preferably a mixture of two or three water-insoluble particulate solids, such as a mixture of two diatomaceous earths and one bentonite clay.
  • diatomaceous earths comprise the major proportion of the solids mixture used. It has been found that large amounts of clay have a deleterious effect on the performance of the present cleaners in that the film which is deposited thereby becomes increasingly difficult to remove.
  • the resultant dispersions are generally stable, preferably for 24 hours, most preferably for at least 3 days to a week at ambient temperature. This stability is desirable for processing reasons, in that time is obtained to store the dispersions in between manufacturing runs, i.e. while different substrates are being prepared, and to prepare the dispersions in large batches which may not be used all at once. Stable dispersions also allow an even application of the solid particles to the substrate sheets.
  • a minor but effective amount of a one or more dispersing agents such as a detergent or surfactant may also be employed to aid in the formation of the dispersion and to aid in the uniform wetting of the sheet.
  • the dispersing agents are used in amounts effective to adhere the solid particles present in the dispersion to the glass surface in an even film, while permitting the ready removal of the film of dispersed dirt and solid particles without smearing, dusting or undue effort.
  • Useful dispersing agents readily adhere to the solid particles and accordingly are removed with the solids when the film is wiped off the glass.
  • Detergents useful in the dispersions of the present invention are generally disclosed in U.S. Pat. Nos. 3,755,180 and 4,062,647, the disclosures of which are incorporated by reference herein, and include the preferred nonionic and anionic synthetic organic detergents.
  • Such detergents include the condensation products of a C 8 -C 2 2 fatty acid with a dimer, trimer or higher polymer of a C 2 -C 5 polyhydric alcohol, i.e., the polyoxyethylene esters of lauric, oleic or stearic acid which incorporate a mole ratio of ethylene oxide to fatty acid of about 1-10:1.
  • a preferred member of this class of detergent is diglycol laurate.
  • anionic detergents include anionic detergent salts having alkyl substituents of 8 to 22 carbon atoms such as the water-soluble higher fatty acid alkali metal soaps , e .g . , sodium myristate and sodium palmitate; water-soluble sulfated and sulfonated anionic alkali metal and alkaline earth metal detergent salts containing a hydrophobia higher alkyl moiety (typically containing from about 8 to 22 carbon atoms) such as salts of higher alkyl mono or polynuclear aryl sulfonates having from about 1 to 16 carbon atoms in the alkyl group (e.g., sodium dodecylbenzenesulfonate, magnesium tridecylbenzenesulfonate), lithium or potassium pentapropylenebenzenesulfonate); alkali metal salts of alkyl naphthalene sulfonic acids (methyl naphthalene sodium sulfonate, Petro
  • salts of sulfated ethylenoxy-derivatized fatty alcoho ls such as the sodium potas sium , o r ammonium s ulfates of the condensation products of about 1-4 moles of ethylene oxide with a
  • the total detergents used will comprise about 0.25-3.0%, preferably from about 0.5-2.5% by weight of the dispersions of the present invention.
  • mixtures of nonionic and anionic detergents will be employed as the dispersing agent, with the nonionic detergent forming the major amount of the mixture.
  • a ratio of nonionic to anionic detergent of about 10-1.5:1, preferably about 9-2:1 has been found to be particularly effective.
  • Polyhydric alcohols such as alkylene diols, glycerol, erythritol, pentaerythritol, and the like have also been found to be useful as optional dispersing agents in proportions similar to those used in the case of detergents.
  • a particularly used polyhydric alcohol is propylene glycol.
  • a minor but effective amount of an inorganic or organic thickening agent such as ammonium carbonate may also comprise an optional component of the present dispersions.
  • the thickening agent will preferably comprise up to about 3.0% by weight of the dispersion for example 0.5-2.0%. It is expected that any ammonium carbonate used to stabilize the present dispersions would be decomposed and driven off during the drying step employed in the preparation of the window cleaners.
  • a hydrocarbon solvent for example an amount of a C 10 -C 14 paraffinic naphthenic hydrocarbon such as kerosene, which is equal to, or less than the amount of detergent used, may optionally be employed.
  • the resulting oil-in-water emulsion has been found to enhance the stability of the particulate dispersion in some cases.
  • up to about 2.5%, preferably 1.1-1.5% by weight of the hydrocarbon solvent is used.
  • the hydrocarbon solvent will also be evaporated from the sheet during the drying process.
  • a minor amount of dye effective to color the dried sheets may also be incorporated into the dispersions, i.e., less than about 0.1% of Rhodamine Pink. Minor amounts of other adjuvants such as fragrance, antimicrobial agents, and the like may also be incorporated into the dispersions in amounts suitable for their intended purposes.
  • preferred aqueous dispersions useful to impregnate porous base sheets to form the glass cleaners of the present invention comprise about 5-25% by weight of a major amount of diatomaceous earth in combination with a minor amount of smectite clay dispersed in water in the presence of about 0.25-3.0% dispersing agent.
  • about 1.1-1.3% inorganic thickener, and about 0.9-1.5% kerosene or similar hydrocarbon solvent mixture may also be employed.
  • the dispersions of the present invention are formed by adding the ingredients to vigorously stirred, hot water until a uniform dispersion has been achieved, then screening the dispersion and applying it to the porous substrate base by any suitable dipping, spraying, or spreading process.
  • the porous substrate base may be formed of any suitably absorbent material, such as thin sheets of fabric, foam or paper, which will absorb about 3-8, and preferably about 4-7 times its dry weight in water, and which possesses a wet strength sufficient to maintain its integrity during the application of the dispersions and upon rewetting and use by the ultimate user.
  • Preferred sheets are those made from cellulosic materials in whole or in part, to provide a highly absorbent product.
  • a useful base can be made from a nonwoven, cellulosic textile bound with a thermoplastic binder such as the air-layered wood fiber Airtex ® SC 150 HL (James River Paper Co., Green Bay, Wisconsin) which weighs about 8 g/sq.ft., has a thickness of about 0.0034 inches and a wet strength of 3050 g/3 in. strip in the machine direction and 2550 g/3 in. strip in the cross direction. Fabrics such as linen and cotton may also be used in, or to form, the base sheet.

  • the dispersed solid particles will comprise up to about 75%, most preferably about 50% by weight of the base sheet.
  • preferred, finished (dried) window cleaners prepared in this manner will comprise a cellulosic support sheet impregnated with about 40-50% by weight of a mixture of solid particles, i.e. about 25-35% diatomaceous earth and about 10-15% smectite clay; about 1-5% nonionic detergent and about 0.5-3% anionic detergent. After drying the sheets will retain only minor amounts of water, i.e. about 1-10%.
  • a 0.8 ft 2 cleaner prepared in this manner is adequate to clean approximately 770 ft 2 of glass.
  • the aqueous dispersion regenerated and available to be spread onto a glass surface when the sheet is wiped across it.
  • a dried strip of the film formed by the application of a wetted window cleaner to a glass surface should be completely removable by no more than 5-6 passes, preferably 1-3 passes of a dry paper towel applied to the film at a pressure of about 1 Ib./sq. inch, a force which approximates the wiping force applied by an average user to the dried film on a vertical glass surface.
  • the dispersion was pumped through a 16 mesh screen and roll-coated onto a 10" wide sheet of Airtex SC 150 HL fiber moving at 100 ft./min.
