Definitions

  • the present invention relates to an improved general purpose cleaning wipe which comprises a wipe combined with a liquid solution comprising surfactant and a combination of water-miscible or soluble solvents.
  • the improved wipe surprisingly accomplishes the desired but difficult-to-achieve goals of enhanced cleaning, with little or no filming or streaking, without buffing the surface cleaned with the wipe.
  • Cleaning wipes have been formulated for specific purposes.
  • cleaning wipes containing inverse emulsions i.e., water-in-lipid
  • These baby wipes are claimed to be more aesthetically pleasant to use on skin, since they essentially contain a waxy coating which, among other characteristics, prevents premature release of the aqueous liquid cleaning composition contained in the inverse emulsion.
  • Examples of these inverse emulsion impregnated wipes are depicted in Cabell et al., U.S. Patent 5,908,707, Mackey et al., WO 97/40814, Mackey et al., WO 96/14835 and Moore, EP 750063. It is quite clear that these types of wipes do not consider improved cleaning of hard surfaces as paramount.
  • U.S. Patent 4,666,621 discloses a pre-moistened, streak-free, lint-free hard surface wiping article.
  • the disclosed liquid formulation consists of a low (1-6) carbon chain length alcohol as the predominant solvent, the loading on the wipe to be 2.5-4.5 times the weight of the wipe.
  • WO 01/38840 discloses improved cleaning wipes in which a combination of a hydrophilic polymer and a nonionic surfactant, preferably a glycoside, improves filming/streaking performance.
  • the present invention is directed to an improved cleaning wipe moistened/impregnated with a liquid cleaning composition in which a surfactant, a short chain alkanol combined with a more hydrophobic solvent, preferably a glycol ether, and water are combined to provide enhanced cleaning of hard surfaces, without the need for rinsing with water, and in which not only is complete cleaning effected, but done so without the leaving of a significant residue, which is typically called streaking/filming, wherein the ratio of short chain alkanol to hydrophobic solvent is from 1.75:1 to 0.5:1, and wherein the liquid cleaner load on the wipe is less than 2.5:1.
  • Surfaces treated with the wipes especially glossy hard surfaces, such as glass, mirrors, chrome, tile, shiny metallic surfaces, painted surfaces, porcelain (or other hard, glossy surfaces, whether made of natural or composite materials), and the like, are rendered brighter and shinier in appearance.
  • the invention is directed to a cleaning wipe which requires no scrubbing, buffing, polishing or rinsing, comprising:
  • the invention is directed to a method for cleaning a hard surface, comprising the steps of:
  • the invention provides an improved cleaning wipe comprising an absorbent/adsorbent wipe, preferably made of at least one layer of nonwoven material, the wipe being impregnated with a liquid cleaner.
  • the wipe provides excellent cleaning with no or little streaking/filming and imparts resistance to soiling to the surface cleaned therewith.
  • the cleaning wipe is preferably impregnated with a liquid cleaner which preferably is a single phase solution or dispersion, having a viscosity generally less than about 1,000 Centipoise ("cps").
  • the liquid cleaner has the following ingredients:
  • adjuncts in small amounts such as cosurfactants, chelating agents, buffers, fragrances, dyes, and the like can be included to provide desirable attributes of such adjuncts.
  • the substrate for the wipe is generally an absorbent or adsorbent material.
  • it is a nonwoven sheet, which is at least one layer, made of wood pulp; or a blend of wood pulp and a synthetic fiber, without limitation, such as polyester, rayon, nylon, polypropylene, polyethylene, other cellulose polymers; or a synthetic fiber or mixture of such fibers.
  • the nonwovens may include nonwoven fibrous sheet materials which include meltblown, coform, air-laid, spun bond, wet laid, bonded-carded web materials, hydroentangled (also known as spunlaced) materials, and combinations thereof. These materials can comprise synthetic or natural fibers or combinations thereof.
  • a binder may or may not be present. Manufacturers include Kimberly-Clark, E.I.
  • Woven materials such as cotton fibers, cotton/nylon blends, or other textiles may also be used herein- Regenerated cellulose, polyurethane foams, and the like, which are used in making sponges, may also be suitable for use herein.
  • the substrate's liquid loading capacity should be at least about 50%-240% of the dry weight thereof, more preferably at least about 100%-240%, and most preferably between about 150%-240%. This is expressed as loading 1 ⁇ 2 to less than 2.5 times the weight (or, more accurately, the mass) of the substrate. This loading of the substrate is very important to the invention, as it will predict greater or lesser streaking/filming performance, as demonstrated by the Experimental Section below.
  • the substrate varies without limitation from about .01 to about 1,000 grams per square meter, most preferably 25 to 120 grams/m 2 (referred to as “basis weight") and typically is produced as a sheet or web which is cut, die-cut, or otherwise sized into the appropriate shape and size.
  • the substrates which are now referred to simply as wipes, can be individually sealed with a heat-sealable or glueable thermoplastic overwrap (such as polyethylene, Mylar, and the like). More preferably the wipes can be packaged as numerous, individual sheets which are then impregnated or contacted with the liquid cleaning ingredients of the invention for more economical dispensing. Even more preferably, the wipes can be formed as a continuous web during the manufacturing process and loaded into a dispenser, such as a canister with a closure, a paper or other material carton with a closure or fold, or a tub with closure. The closure is to seal the moist wipes from the external environment and to prevent premature volatilization of the liquid ingredients.
  • a heat-sealable or glueable thermoplastic overwrap such as polyethylene, Mylar, and the like.
  • the wipes can be packaged as numerous, individual sheets which are then impregnated or contacted with the liquid cleaning ingredients of the invention for more economical dispensing. Even more preferably, the wipes can be formed
  • the dispenser may be formed of plastic, such as high density polyethylene, polypropylene, polycarbonate, polyethylene pterethalate (PET), polyvinyl chloride (PVC), or other rigid plastics; or, of paper, cartonboard, or other material.
  • the continuous web of wipes could preferably be threaded through a thin opening in the top of the dispenser, most preferably, through the closure. A means of sizing the desired length or size of the wipe from the web would then be needed.
  • a knife blade, serrated edge, or other means of cutting the web to desired size can be provided on the top of the dispenser, for non-limiting example, with the thin opening actually doubling in duty as a cutting edge.
  • the continuous web of wipes could be scored, perforated, folded, segmented, or partially cut into uniform or non-uniform sizes or lengths, which would then obviate the need for a sharp cutting edge.
  • the wipes could be interleafed, so that the removal of one wipe advances the next, and so forth.
  • the wipes will preferably have a certain wet tensile strength which is without limitation about 25 to about 250 Newtons/m, more preferably about 75-170 Newtons/m.
  • the liquid cleaner is impregnated, dosed, loaded, metered; or otherwise dispensed onto the wipe.
  • each individual wipe could be treated with a discrete amount of liquid cleaner. More preferably, a mass treatment of a continuous web of wipes with the liquid cleaner will ensue. In some cases, an entire web of wipes could be soaked in the cleaner. In other cases, while the web is being spooled, or even during the creation of the nonwoven material, the liquid cleaner could be sprayed or otherwise metered onto the web.
  • a mass, such as a stack of individually cut and sized wipes could also be impregnated in its container by the manufacturer, or, even by the user. What follows is a description of the individual constituents of the liquid cleaner.
  • An essential part of the invention lies in the use of a low residue surfactant, which an alkali metal (sodium, potassium, lithium counterion; ammonium is also a possibility) alkyl diphenyl oxide disulfonate, as the major surfactant portion of the liquid cleaner used to impregnate the wipe.
  • alkali metal alkyl diphenyl oxide disulfonates are atypical surfactants and preferably include an alkyl chain group of C 6-20 .
  • the preferred alkali metal alkyl diphenyl oxide disulfonates are from Dow under the brand name Dowfax. Especially preferred is Dowfax 2A1, a sodium dodecyl diphenyl oxide disulfonate. Pilot Chemical, with Calfax, is another source of the alkyl diphenyl oxide sulfonate surfactant.
  • the amounts of surfactants present are to be somewhat minimized, for purposes of cost-savings and to generally restrict the dissolved actives which could contribute to leaving behind residues when the composition is applied to a surface.
  • the amounts added are generally 0.001-6%, more preferably 0.002-4.00% surfactant. These are generally considered to be cleaning-effective amounts.
  • a key to the invention is the use of a combination of solvents in the liquid cleaner: a C 2-4 alkanol with a more hydrophobic solvent, most preferably, a glycol ether.
  • the two solvents should be in a ratio of short chain alkanol to hydrophobic solvent from 1.75 : 1 to 0.5 : 1. Further, in the invention, the completed liquid cleaner load on the wipe is less than 2.5 : 1.
  • a further water soluble or dispersible organic solvent having a vapor pressure of at least 0.001 mm Hg at 25°C, such as selected from C 1-6 alkanols, C 1-6 diols, C 1-6 alkyl ethers of alkylene glycols and polyalkylene glycols, and mixtures thereof.
  • the C 2-4 alkanol can be selected from ethanol, n-propanol, isopropanol, the various positional isomers of butanol, and mixtures of the foregoing. It is, however, most preferred to use isopropyl alcohol (also referred to as isopropanol) or 2-propanol (sometimes referred to hereinafter as "IPA").
  • the second, important solvent is a more hydrophobic solvent, preferably, an alkylene glycol ether solvent in this invention.
  • alkylene glycol ether solvent can include, for example, monoalkylene glycol ethers such as ethylene glycol monopropyl ether, ethylene glycol mono-n-butyl ether, propylene glycol monopropyl ether, and propylene glycol mono-n-butyl ether, and polyalkylene glycol ethers such as diethylene glycol monoethyl or monopropyl or monobutyl ether, di- or tri-polypropylene glycol monomethyl or monoethyl or monopropyl or monobutyl ether, etc., and mixtures thereof. Additionally, acetate and propionate esters of glycol ethers may be used.
  • the most preferred glycol ether is propylene glycol mono n-butyl ether, Dowanol PnB, from Dow Chemical Company.
  • Additional water insoluble solvents may be included in minor amounts (0-1%). These include isoparaffinic hydrocarbons, mineral spirits, allcylaromatics, and terpenes such as d-limonene. Additional water soluble solvents may be included in minor amounts (0-1%). These include pyrrolidones, such as N-methyl-2-pyrrolidone, N-octyl-2-pyrrolidone and N-dodecyl-2-pyrrolidone.
  • the total amount of solvents is preferably no more than about 20%, and more preferably, no more than about 10%, of the cleaner.
  • a particularly preferred range is about 1-10%.
  • These amounts of solvents are generally referred to as dispersion-effective or solubilizing-effective amounts.
  • the solvents, especially the glycol ethers, are also important as cleaning materials on their own, helping to loosen and solubilize greasy or oily soils from surfaces cleaned. But the volatile solvents, such as IPA, are necessary to prevent the leaving of residues on the surface cleaned.
  • surfactant and solvents of the invention provide excellent cleaning performance, it may sometimes be desired to add small amounts of cosurfactants to the formulations to obtain additional cleaning benefits.
  • the surfactant may be used in conjunction with other nonionic or amphoteric surfactants, or mixtures thereof, such as are known in the art. Such surfactants are described, for example, in McCutcheon's Emulsifiers and Detergents (1997).
  • Illustrative nonionic surfactants are the ethylene oxide and mixed ethylene oxide propylene oxide adducts of alkylphenols, the ethylene oxide and mixed ethylene oxide / propylene oxide adducts of long chain alcohols or of fatty acids, mixed ethylene oxide / propylene oxide block copolymers, esters of fatty acids and hydrophilic alcohols, such as sorbitan monooleate, alkanolamides, and the like.
  • amphoteric surfactants are those which have both acidic and basic groups in their structure, such as amino and carboxyl radicals or amino and sulfonic radicals, or amine oxides and the like.
  • Suitable amphoteric surfactants include betaines, sulfobetaines, imidazolines, and the like.
  • cosurfactants will generally be about less than the level of the primary low residue surfactant. It is probably less preferred to include either other anionic or cationic surfactants, because of their tendency to leave residues. However, judicious formulation with other dispersing aids may allow for the use of these latter surfactants.
  • Polymers may or may not be added to the liquid formulations herein.
  • a list of possibly appropriate polymers may be found in co-pending application Serial No. 09/448,703, filed November 24, 1999, of Malcolm A. Deleo et al., of common assignment herewith. Mixtures of any of the foregoing polymers may be possible or desirable.
  • the hydrophilic polymer or polymers are present at a level of about 0.001-5%, more preferably, about 0.001-1 % of the liquid cleaner.
  • Chelants useful herein include the various alkali metal, ammonium and substituted ammonium polyacetates, carboxylates, polycarboxylates and polyhydroxysulfonates.
  • Non-limiting examples of polyacetate and polycarboxylate builders include the sodium, potassium, lithium, ammonium and substituted ammonium salts of ethylenediamine tetraacetic acid, ethylenediamine triacetic acid, ethylenediamine tetrapropionic acid, diethylenetriamine pentaacetic acid, nitrilotriacetic acid, oxydisuccinic acid, iminodisuccinic acid, mellitic acid, polyacrylic acid or polymethacrylic acid and copolymers, benzene polycarboxylic acids, gluconic acid, sulfamic acid, oxalic acid, phosphoric acid, phosphonic acid, organic phosphonic acids, acetic acid, and citric
  • chelating agents may also exist either partially or totally in the hydrogen ion form, for example, citric acid or disodium dihydrogen ethylenediamine tetraacetate, depending upon the pH of the liquid formulation.
  • the substituted ammonium salts include those from methylamine, dimethylamine, butylamine, butylenediamine, propylamine, triethylamine, trimethylamine, monoethanolamine, diethanolamine, triethanolamine, isopropanolamine, and propanolamine. Most preferred is monoethanolamine.
  • chelating agents are the mono-, di-, tri-, and tetrapotassium and ammonium salts of ethylenediamine tetraacetic acid. See, for example, Robbins et al., U.S. Patents 6,242,401, 6,159,916, 6,214,784, 5,972,876, Chang et al., U.S. Patent 5,948,742, Ochomogo et al., U.S. Patent 5,948,741, and Mills et al., U.S. 5,814,591.
  • the amount of chelant added should be in the range of 0.001-2%, more preferably 0.001-2%, by weight of the cleaner.
  • the cleaner is an aqueous cleaner with relatively low levels of actives
  • the principal ingredient is water, which should be present at a level of at least about 70%, more preferably at least about 80%, and most preferably, at least about 90%.
  • Distilled, deionized, or industrial soft water is preferred so as not to contribute to formation of a residue and to avoid the introduction of undesirable metal ions.
  • Buffering and pH adjusting agents may be desirable components. These would include minute amounts of inorganic agents such as alkali metal and alkaline earth salts of silicate, metasilicate, borate, carbonate, carbamate, phosphate, ammonia, and hydroxide.
  • Organic buffering agents such as monoethanolamine, monopropanolamine, diethanolamine, dipropanolamine, triethanolamine, and 2-amino-2-methylpropanol are also desirable.
  • adjuncts can be added for improving aesthetic qualities of the invention.
  • Aesthetic adjuncts include fragrances or perfumes, such as those available from Givaudan-Rohre, International Flavors and Fragrances, Quest, Sozio, Firmenich, Dragoco, Norda, Bush Boake and Allen and others, and dyes or colorants which can be solubilized or suspended in the formulation. Further solubilizing materials, such as hydrotropes (e.g., water soluble salts of low molecular weight organic acids such as the sodium or potassium salts of xylene sulfonic acid), may also be desirable.
  • Adjuncts for cleaning include additional surfactants, such as those described in Kirk-Othmer, Encyclopedia of Chemical Technology.
  • Dyes or colorants which can be solubilized or suspended in the formulation such as diaminoanthraquinones, may be added, although it is cautioned that since leaving little or no residue is an objective of the invention, that only minute amounts should be used.
  • Thickeners such as polyacrylic acid, xanthan gum, alginates, guar gum, methyl, ethyl and propylhydroxycelluloses, and the like, may be desired additives, although the use of such polymers is to be distinguished from the previously mentioned hydrophilic polymers in 6 above.
  • Defoamers such as, without limitation, silicones, aminosilicones, silicone blends, silicone/hydrocarbon blends, and the like, available from Dow Coming, Wacker, Witco, Ross and Hercules.
  • the amounts of these aesthetic adjuncts should be in the range of 0-2%, more preferably 0-1 %.

  • Examples of the substrates from which the wipes are made include: TABLE II Manufacturer and Item Description DuPont 8838 and 8892 Spunlaced Pulp-Polyester Blends Kimberly Clark Hydroknit Spunlaced Pulp-Polypropylene Kimberly Clark Spunbond Spun, Fine Fiber Polypropylene Kimberly Clark Meltblown PP/EHRT Meltblown Polypropylene American Nonwovens, ANC 4297 Carded Nonwoven, 70/30 Rayon/Polyester American Nonwovens, ANC 4297 Carded Nonwoven, 100 Rayon James River Pulp or Pulp Blends Dexter 10180 Hydrospun Spunlaced Pulp Blend Dexter ZA-0155 Spunlaced Pulp-Polyester Blends Dexter 8589 Rayon/Pulp Blend Dexter 4459 Pulp/Polyethylene Blend
  • the test surfaces were glass mirror tiles at different temperatures (35°F, or, 1.66°C; 70°F or 21°C; 100°F or 37.7°C) which were wiped for 3 strokes back and forth in a similar manner and evaporation times were measured. Unexpectedly, rapid evaporation times, particularly at 35°F, are predictive of good streaking/filming performance.
  • a panel study was coordinated with 26 panelists to grade the streaking caused by wiping soiled mirrors.
  • a car soil (sebum, air borne soil, triethanolamine, carbon black) was developed and 0.2g of the soil sprayed on clean mirrors.
  • a premoistened wipe wound over by a fixed weight was wiped 10 times in a circular motion on the soiled mirror, allowed to dry and visually graded.
  • the controls were Clorox® Disinfecting Wipes (most streaking; most likely due to the presence of a germicide in the formula) and Windex® sprayed and buffed with a Kim-Wipe® (least streaking).
  • the next set of examples further confirms the use of evaporation rates at low temperatures as predictive of good streaking/filming performance, as well as confirming the need to maintain a cleaner/wipes load of less than 2.5.
  • a larger panel of panelists graded the filming/streaking caused by wiping soiled mirrors.
  • a car soil (sebum, airborne soil, triethanolamine, carbon black) was developed and a small amount (less than 0.5g) was sprayed onto clean mirrors.
  • a premoistened wipe (containing the liquid cleaners depicted in Table V) was used to wipe 10 times in a circular motion on the soiled mirror, allowed to dry and visually graded by the panelists on a 1 to 10 scale (score of 10 meaning “least soiled", a score of 1 meaning “most filming/streaking”).
  • the controls were Clorox® Disinfecting Wipes ("CDW”; most streaking) and Windex® cleaner sprayed once/buffed with a Bounty® paper towel (least streaking; it is again observed that this compares the performance of a spray cleaner with a dry, clean cloth, with repeated wiping. Thus, this control is very different from and not as convenient to use as a premoistened wipe).
