HARD SURFACE CLEANING COMPOSITIONS, PREMOISTENED WIPES, METHODS OF USE,

AND ARTICLES COMPRISING SAID COMPOSITIONS OR WIPES AND INSTRUCTIONS FOR

) USE RESULTING IN EASIER CLEANING AND MAINTENANCE, IMPROVED SURFACE : APPEARANCE AND/OR HYGIENE UNDER STRESS CONDITIONS SUCH AS NO-RINSE

FIELD OF THE INVENTION

This invention relates to liquid cleaning compositions, including concentrated compositions, premoistened wipes, including optimized substrates, and implements for use in cleaning hard surfaces and/or maintaining their appearance and hygiene, and articles comprising said compositions, concentrates, wipes, and the like, in association with instructions as to how to use them to provide superior performance. These compositions, wipes, and implement designs along with specific instructions for use are advantageous for use on hard surfaces including bathroom surfaces, glass surfaces, countertops, walls and floors. Such compositions typically contain hydrophilic polymer, detergent surfactant, organic cleaning solvent, and optional volatile buffers, perfume, anti-microbials, builders, and the like.

BACKGROUND OF THE INVENTION

] The use of detergent compositions comprising organic water-soluble synthetic detergent ’ surfactants, polymers, and cleaning solvents for cleaning hard surfaces in, e.g., bathrooms, is well established. Known liquid detergent compositions for this purpose comprise organic cleaning . solvents, detergent surfactant, and optional detergent builders and/or abrasives. The compositions can be acidic for improved removal of hard water deposits.

Liquid cleaning compositions are usually preferred, since they have the advantage that they can be applied to hard surfaces in neat or concentrated form so that a relatively high level of, eg. surfactant material and/or organic solvent is delivered directly to the soil. However, solid compositions can also be used to form a cleaning solution when diluted with water. Concentrated liquid cleaning compositions can also help improve the value eguation for consumers by economizing on packaging costs, where the concentrated products are intended to be used in more dilute form. A concentrated, e.g., 10X refill, can also provide additional convenience to the consumer in that it lasts longer, weighs less, and occupies less space than a 1X product. Liquid cleaning compositions in the form of a “wipe” also can provide convenience by allowing the consumer to use the wipe once and dispose of it. : Implements are important in that they can be used to advantageously improve the performance of the liquid compositions. Implements, including wipes, pads, mops and the like, can provide important mechanical cleaning properties to complement the liquid composition choice. Conversely, the liquid cornpositions can be chosen to suit the choice of implement. Thus, the proper choice of implement allows for a significant reduction in the level of non-volatile : surfactants and other adjuvants needed to achieve excellent cleaning results.

SUMMARY OF THE INVENTION

The present invention relates to hard surface cleaning compositions, preferably liquid, suitable for removal of and/or prevention of buildup of soils commonly encountered on floors, walls, counter tops, glass, and/or in the bathroom, said compositions preferably comprising hydrophilic polymers, to render the cleaned surface hydrophilic, and/or specific surfactant, preferably alkylpolyglycoside surfactant, selected to minimize spotting/fiiming, optionally cleaning solvents, and optionally organic acids. The invention also relates to cleaning systems including implements and instructions for how they are used, preferably, with the solutions comprising hydrophilic polymers to achieve a low residue end result. The invention further relates to methods of cleaning and maintaining the cleanliness of hard surfaces, especially those that are present in the bathroom, kitchen, laundry, etc., wherein one can treat the surface and let the treatment solution dry without scrubbing and/or rinsing, e.g., the treatment is preferably a no-rinse treatment. “No-rinse treatment’, e.g. cleaning of hard surfaces without rinsing, as used herein, means that at least a substantial part of the surface treatment solution dries down on the treated surface. Such treatment solutions are preferably highly dilute. Typically, the surface is then later, after the surface is used again, exposed to water, or another cleaning solution. Preferably, the surface is one that is normally exposed to water on a regular basis, such as showers, tubs, sinks, : etc. ) The invention also relates to compositions and methods of use in which floors, counters, ) 20 walls, and the like, are cleaned by applying a treatment solution which is then substantially removed by absorption and/or rubbing, while leaving on a low to moderate level of treatment liquid which then dries. Examples of such methods include applications such as the use of pre- moistened wipes (comprising a substrate and aqueous compositions incorporated in the substrate) and/or absorbent articles used in conjunction with cleaning solution. The use of these implements facilitates the ease of use and can be advantageous in achieving not only a desired end result but excellent hygiene. Since pre-moistened wipes or absorbent pads are typically disposed of after each use, their use and subsequent disposal reduces the risk of the implement harboring and re-inoculating germs onto the surface being cleaned which often happens with traditional re-usable sponges, cloths, and mops. The disclosures of premoistened wipes and disposable cleaning pads are found hereinafter.

The acidic versions of the present hard surface cleaning compositions can remove soap scum and hard water marks. The compositions can have disinfectant properties achieved through the choice of antibacterial actives, including citric acid, and can be used with, or without, additives such as hydrogen peroxide for additional mold/mildew prevention benefits. As stated above, the compositions preferably incorporate one or more hydrophilic polymers which attach to the surface to render it hydrophilic, as measured by, e.g., the contact angle, for improved surface wetting and/or filming/streaking properties and, optionally, viscosity control.

a

The hard surface cleaning compositions herein which contain the hydrophilic polymers, provide superior surface appearance, especially in a no-rinse application. Thus, in the context of a “daily shower” spray application, the compositions herein are sprayed directly onto tile, more preferably onto wet tile, and then allowed to dry. Upon the next exposure to water, e.g. during a

S shower, the dried-on, though not visible, residue allows for even faster wetting of the surface.

Consequently, the product works better, when it is not rinsed or wiped off after use, in subsequent cleaning procedures. Additionally, the fact that no, or limited, rinsing or wiping is involved after the product is applied improves performance with continued use. One of the benefits of the preferred polymers herein is that they ultimately reach a steady state concentration on the hard surfaces on which they are sprayed. No build-up occurs because the preferred polymers are water soluble, and once steady state concentrations are reached, “fresh” polymer deposited on the surface is offset by polymer which is dissolved by the solution. The reduction of contact angle of water can be improved over several cycles, even for compositions that contain essentially no surfactant.

In the context of a floor, counter, wall cleaner, or the like, the steady state concentration achieved after applying a solution composition, wiping and removing a substantial amount by absorption and allowing a low to moderate level of treatment to dry is also important. In these cases the Jow level of residue (residue being defined as non-volatile actives) makes next time - cleaning even easier by providing even better wetting upon subsequent application, thus reducing streaking/filming potential by minimizing solution de-wetting which is particularly important on very hydrophobic surfaces. This effective wetting benefit provided by polymer at low levels also allows the formulator to keep other ingredients in the composition, such as surfactants, that are typically involved in wetting, at a minimum. This reduces the possibility of obtaining a fitm that can smudge and/or cause surface stickiness due to the presence on the surface of too much active : 25 and/or other material. This is important, as it allows for less stickiness with prolonged product use.

Accordingly, the cleaning process is preferably a method which comprises using treatment solution (preferably a ready-to-use-solution) comprising: a. an effective amount to reduce the contact angle andlor increase surface hydrophilicity, up to about 0.5%, preferably from about 0.005% to about 0.4%, more preferably from about 0.01% to about 0.3%, by weight of the composition, of hydrophilic polymer, preferably substantive, that renders the treated surface hydrophilic, and preferably is a polymer selected from the group consisting of: polystyrene sulfonate; polyvinyl pyrrolidone; polyvinyl pyrrolidone acrylic acid copolymer; polyvinyl pyrrolidone acrylic acid copolymer sodium salt, polyvinyl pyrrolidone acrylic acid copolymer potassium salt, polyvinyl pyrrolidone- vinyl imidazoline; polyvinyl pyridine; polyvinyl pyridine n-oxide; and mixtures thereof, and more preferably polyvinyl pyridine n-oxide;

The improved surface appearance is the result of the use of the hydrophilic polymer and/or specific surfactant, especially the alkyl polysaccharide, and especially the use of only low levels of all ingredients. For no-rinse and/or limited "buffing” methods, the specific alkyl polysaccharide is important for appearance, even without the polymer being present.

Concentrates of the above product can be made by reducing the amount of water. Concentrates of the solution of the present invention (i.e., products intended to be used diluted) have levels of active that are scaled up by the stated concentration factor.

Examples of concentrates of the present invention include, but are not limited to, 3X, 5X and 10 X products according to the specification levels defined above. Unless otherwise specified, all concentrations are implied to be for “ready-to-use” products hereinafter. It is understood that those skilled in the art would be able to make concentrates, which would then be diluted for use.

DETAILED DESCRIPTION OF THE INVENTION

The hard surface cleaning compositions of the present invention are especially useful for maintaining the appearance of hard surfaces and the buildup of hard-to-remove soils that are commonly encountered on floors and/or in the bathroom. These include hard water stains, fatty acids, triglycerides, lipids, insoluble fatty acid soaps, entrenched particulate matter, encrusted food, and the like. The detergent compositions can be used on many different surface types, such as ceramic, fiber glass, glass, polyurethane, metallic surfaces, plastic surfaces, and laminates of all the above. a. Hydrophilic Polymer in most of the embodiments of the invention, the polymeric material that improves the hydrophilicity of the surface being treated is essential. This increase in hydrophilicity provides improved final appearance by providing “sheeting” of the water from the surface and/or spreading . of the water on the surface, and this effect is preferably seen when the surface is rewetted and even when subsequently dried after the rewetting. . In the context of a product intended to be used as a daily shower product, the “sheeting” : effect is particularly noticeable because most of the surfaces treated are vertical surfaces. Thus, benefits have been noted on glass, ceramic and even tougher to wet surfaces such as porcelain . 20 enamel. When the water "sheets" evenly off the surface and/or spreads on the surface, it minimizes the formation of, e.g., "hard water spots" that form upon drying. For a product intended to be used in the context of a floor cleaner, the polymer improves surface wetting and assists cleaning performance. ~ Polymer substantivity is beneficial as it prolongs the sheeting and cleaning benefits.

Another important feature of preferred polymers is lack of residue upon drying. Compositions comprising preferred palymers dry more evenly on floors while promoting an end result with little or no haze.

Many materials can provide the sheeting and anti-spotting benefits, but the preferred materials are polymers that contain amine oxide hydrophilic groups. Polymers that contain other hydrophilic groups such a sulfonate, pyrrolidone, and/or carboxylate groups can also be used.

Examples of desirable poly-sulfonate polymers include polyvinylsulfonate, and more preferably polystyrene sulfonate, such as those sold by Monomer-Polymer Dajac (1675 Bustleton Pike,

Feasterville, Pennsylvania 19053). A typical formula is as follows. -[CH{CgH4S03Na) - CHo)h- CH(CgHs) - CH - wherein n is a number to give the appropriate molecular weight as disclosed below.

Typical molecular weights are from about 10,000 to about 1,000,000, preferably from about 200,000 to about 700,000. Preferred polymers containing pyrrolidone functionalities include polyvinyl pyrrolidone, quaternized pyrrolidone derivatives (such as Gafquat 755N from

) international Specialty Products), and co-polymers containing pyrrolidone, such as polyvinylpyrrolidone /dimethylaminoethylmethacrylate (available from ISP) and polyvinyl ] pyrrolidone/acryiate (available from BASF). Other materials can also provide substantivity and - hydrophilicity including cationic materials that also contain hydrophilic groups and polymers that ) 5 contain multiple ether linkages. Cationic materials include cationic sugar and/or starch derivatives - and the typical block copolymer detergent surfactants based on mixtures of polypropylene oxide ) and ethylene oxide are representative of the polyether materials. The polyether materials are less substantive, however. } The preferred polymers comprise water-soluble amine oxide moieties. It is believed that the partial positive charge of the amine oxide group can act to adhere the polymer to the surface of the surface substrate, thus allowing water to "sheet" more readily. The amine oxide moiety can also hydrogen-bond with hard surface substrates, such as ceramic tile, glass, fiberglass, porcelain enamel, linoleum, no-wax tile, and other hard surfaces commonly encountered in consumer homes. To the extent that polymer anchoring promotes better “sheeting”, higher molecular weight materials are preferred. Increased molecular weight improves efficiency and effectiveness of the amine oxide-based polymer. The preferred polymers of this invention have one or more monomeric units containing at least one N-oxide group. At least about 10%, preferably more than about 50%, more preferably greater than about 90% of said monomers forming said polymers . contain an amine oxide group. These polymers can be described by the general formula:

P(B) wherein each P is selected from homopolymerizable and copolymerizable moieties which attach ) to form the polymer backbone, preferably vinyl moieties, e.g. C(R), --C(R),, wherein each R is H,

C1 -Cy2 (preferably Cy -C,) alkyl(ene), Cs -Cs; aryl(ene) and/or B; B is a moiety selected from substituted and unsubstituted, linear and cyclic C, -C,, alkyl, C,-C,, alkylene, C,-C.2 heterocyclic, ‘ 25 aromatic C¢-Cy2 groups and wherein at least one of said B moieties has at least one amine oxide (-N—0) group present; wherein the polymer typically has at least about 10% to about 90% monomers containing an amine oxide group; and the average molecular weight of the polymer is from about 2,000 to about 500,000, preferably from about 5,000 to about 250,000, and more preferably from about 7,500 to about 200,000.

The preferred polymers of this invention possess the unexpected property of being substantive without leaving a visible residue that would render the surface substrate unappealing to consumers. The preferred polymers include poly(4-vinylpyridine N-oxide) polymers (PVNO), e.g. those formed by polymerization of monomers that include the following moiety: 16) ! ’d g vy » (ih wherein the average molecular weight of the polymer is from about 2,000 to about 500,000 preferably from about 5,000 to about 400,000, and more preferably from about 7,500 to about 300,000. in general, higher molecular weight polymers are preferred. Often, higher molecular weight polymers allow for use of lower levels of the wetting polymer, which can provide benefits in floor cleaner applications. The desirable molecular weight range of polymers useful in the present invention stands in contrast to that found in the art relating to polycarboxylate, polystyrene sulfonate, and polyether based additives which prefer molecular weights in the range of 400,000 to 1,500,000. Lower molecular weights for the preferred poly-amine oxide polymers of the present invention are due to greater difficulty in manufacturing these polymers in higher molecular weight.

The level of amine oxide polymer will normally be less than about 0.5%, preferably from about 0.005% to about 0.4%, more preferably from about 0.01% to about 0.3%, by weight of the end use composition/solution.

Some non-limiting examples of homopalymers and copolymers which can be used as water-soluble polymers of the present invention are: adipic acid/ dimethylaminohydroxypropyi diethylenetriamine copolymer; adipic acid/epoxypropy! diethylenetriamine copolymer; polyvinyl alcohol; methacryloyl ethyl Dbetaine/methacrylates copolymer; ethyl acrylate/methyl ) methacrylate/methacrylic acid/acrylic acid copolymer; polyamine resins; polyquaternary amine resins; poly(ethenylformamide); poly(vinylamine) hydrochloride; poly(vinyl alcohol-co-6% i 20 vinylamine); poly(vinyl alcohol-co-12% vinylamine); poly(vinyl alcohol-co-6% vinylamine hydrochloride); poly(vinyl alcohol-co-12% vinylamine hydrochloride); and mixtures thereof.

Preferably, said copolymer and/or homopolymers are selected from the group consisting of adipic acid/dimethylaminohydroxypropy!l diethylenetriamine copolymer; poly(vinylpyrrolidone/dimethylaminoethyl methacrylate); polyvinyl alcohol; ethyl acrylate/methyl methacrylate/methacrylic acid/acrylic acid copolymer; methacryloyl ethyl betaine/methacrylates copolymer; polyquaternary amine resins; poly(ethenylformamide); poly(vinylamine) hydrochloride; poly(vinyl alcohol-co-6% vinylamine); poly(vinyl alcohol-co-12% vinylamine); poly(vinyl alcohol-co- 6% vinylamine hydrochloride); poly(vinyl alcohol-co-12% vinylamine hydrochloride); and mixtures thereof.

Polymers useful in the present invention can be selected from the group consisting of copolymers of hydrophilic monomers. The polymer can be linear random or block copolymers, and mixtures thereof. The term "hydrophilic" is used herein consistent with its standard meaning of having affinity for water. As used herein in relation to monomer units and polymeric materials, including the copolymers, “hydrophilic” means substantially water soluble. In this regard, “substantially water soluble” shall refer to a material that is soluble in distilled (or equivalent) water, at 25°C, at a concentration of about 0.2% by weight, and are preferably soluble at about 1% by weight. The terms “soluble”, "solubility" and the like, for purposes hereof, correspond to

- the maximum conceniration of monomer or polymer, as applicable, that can dissolve in water or other solvents to form a homogeneous solution, as is well understood to those skilled in the art.

Nontimiting examples of useful hydrophilic monomers are unsaturated organic mono- and polycarboxylic acids such as acrylic acid, methacrylic acid, crotonic acid, maleic acid and its half esters, and itaconic acid; unsaturated alcohols, such as vinyl alcohol and ally! alcohol; polar vinyl heterocyclics such as vinyl caprolactam, vinyl pyridine, and vinyl imidazole; vinyl amine; vinyl sulfonate, unsaturated amides such as acrylamides, e.g., N,N-dimethylacrylamide and N-t-butyl acrylamide; hydroxyethyl methacrylate; dimethylaminoethyl methacrylate; salts of acids and amines listed above; and the like; and mixtures thereof. Some preferred hydrophilic monomers t0 are acrylic acid, methacrylic acid, N,N-dimethyl acrylamide, N,N-dimethyl methacrylamide, N-t- butyl acrylamide, dimethylamino ethyl methacrylate, and mixtures thereof.

Polycarboxylate polymers are those formed by polymerization of monomers, at least some of which contain carboxylic functionality. Common monomers include acrylic acid, maleic acid, ethylene, vinyl pyrrolidone, methacrylic acid, methacryloylethylbetaine, and the like. Preferred polymers for substantivity are those having higher molecular weights. For example, polyacrylic acid having molecular weights below about 10,000 are not particularly substantive and therefore do not normally provide hydrophilicity for three rewettings with all compositions, although with higher ievels and/or certain surfactants like amphoteric and/or zwitterionic detergent surfactants, . molecular weights down to about 1,000 can provide some results. In general, the polymers should have molecular weights of more than about 10,000, preferably more than about 20,000, more preferably more than about 300,000, and even more preferably mare than about 400,000. It has also been found that higher molecular weight polymers, e.g., those having molecular weights of more than about 3,000,000, are extremely difficult to formulate and are less effective in providing anti-spotting benefits than lower molecular weight polymers. Accordingly, the molecular weight should normally be, especially for polyacrylates, from about 20,000 to about 3,000,000; preferably from about 20,000 to about 2,500,000; more preferably from about 300,000 to about 2,000,000; and even more preferably from about 400,000 to about 1,500,000.

An advantage for some polycarboxylate polymers is the detergent builder effectiveness of such polymers. Although such polymers do increase filming/streaking, like other detergent builders, they provide increased cleaning effectiveness on typical, common "hard-to-remove” soils that contain particulate matter.

Some polymers, especially polycarboxylate polymers, thicken the compositions that are aqueous liquids. This can be desirable. However, when the compositions are placed in containers with trigger spray devices, the compositions are desirably not so thick as to require excessive trigger pressure. Typically, the viscosity under shear should be less than about 200 cp, preferably less than about 100 cp, more preferably less than about 50 cp. It can be desirable, however, to have thick compositions to inhibit the flow of the composition off the surface, especially vertical surfaces.

Cn

Non limiting examples of polymers for use in the present invention include the following: poly(vinyl pyrrolidone/acrylic acid) sold under the name Acrylidone® by ISP and poly(acrylic acid) sold under the name Accumer® by Rohm & Haas. Other suitable materials include sulfonated polystyrene polymers sold under the name Versaflex® sold by National Starch and Chemical

Company, especially Versaflex® 7000.

The level of polymeric material will normally be less than about 0.5%, preferably from about 0.01% to about 0.4%, more preferably from about 0.01% to about 0.3%. In general, lower molecular weight materials such as lower molecular weight poly(acrylic acid), e.g., those having molecular weights below about 10,000, and especially about 2,000, do not provide good anti- spotting benefits upon rewetting, especially at the lower levels, e.g., about 0.02%. One should use only the more effective materials at the lower levels. In order to use lower molecular weight materials, substantivity should be increased, e.g., by adding groups that provide improved attachment to the surface, such as cationic groups, or the materials should be used at higher levels, e.g., more than about 0.05%. b. Surfactant

When the polymer is not present in the compositions herein, the compositions will normally have one of the preferred surfactants present, such as alkylpolysaccharides or nonionic : surfactants, including alkyl ethoxylates. The preferred surfactants for use herein are the alkylpolysaccharides that are disclosed in U.S. Patents: 5,776,872, Cleansing compositions, issued July 7, 1998, to Giret, Michel Joseph; Langlois, Anne; and Duke, Roland Philip; 5,883,059, Three in one ultra mild lathering antibacterial liquid personal cleansing composition, issued March 16, 1999, to Furman, Christopher Allen; Giret, Michel Joseph; and Dunbar, James

May 25, 1999, Process for cleaning vertical or inclined hard surfaces, by Ouzounis, Dimitrios and

Nierhaus, Wolfgang; all of which are incorporated herein by reference.

Suitable alkylpolysaccharides for use herein are disclosed in U.S. Pat. No. 4,565,647,

Lienado, issued Jan. 21, 1986, which is incorporated herein by reference, having a hydrophobic group containing from about 6 to about 30 carbon atoms, preferably from about 10 to about 16 carbon atoms and a polysaccharide, e.g., a polyglycoside, hydrophilic group. For acidic or alkaline cleaning compositions/solutions suitable for use in no-rinse methods, the preferred alkyl polysaccharide preferably comprises a broad distribution of chain lengths, as these provide the best combination of wetting, cleaning, and low residue upon drying. This "broad distribution” is defined by at least about 50% of the chainlength mixture comprising from about 10 carbon atoms to about 16 carbon atoms. Preferably, the alkyl group of the alkyl polysaccharide consists of a mixtures of chainiength, preferably from about 6 to about 18 carbon atoms, more preferably from about 8 to about 16 carbon atoms, and hydrophilic group containing from about 1 to about 1.5 saccharide, preferably glucoside, groups per moiecule. A broad mixture of chain lengths,

particularly Cg-Cye, is highly desirable relative to narrower range chain length mixtures, and particularly versus lower (i.e., Cg-Cyo Or C5-C43) chainlength alkyl polyglucoside mixtures. It is also found that the preferred Cs.46 alkyl polyglucoside provides much improved perfume solubility versus lower and narrower chainlength alkyl polyglucosides, as well as other preferred surfactants, including the Ce-C.4 alkyl ethoxylates. Any reducing saccharide containing 5 or 6 carbon atoms can be used, e.g., glucose, galactose and galactosyl moieties can be substituted for the glucosyl moieties. (optionally the hydrophobic group is attached at the 2-, 3-, 4-, etc. positions thus giving a glucose or galactose as opposed to a glucoside or galactoside). The intersaccharide bonds can be, e.g., between the one position of the additional saccharide units and the 2-, 3-, 4-, and/or 6- positions on the preceding saccharide units. The glycosyl is preferably derived from glucose.

Optionally, and less desirably, there can be a polyalkyleneoxide chain joining the hydrophobic moiety and the polysaccharide moiety. The preferred alkyleneoxide is ethylene oxide. Typical hydrophobic groups include alkyl groups, either saturated or unsaturated, branched or unbranched containing from 8 to 18, preferably from 10 to 16, carbon atoms. Preferably, the alkyl group is a straight-chain saturated alkyl group. The alkyl group can contain up to about 3 hydroxyl groups and/or the polyalkyleneoxide chain can contain up to about 10, preferably less than 5, alkyleneoxide moieties. Suitable alkyl polysaccharides are octyl, nonyidecyl, . undecyldodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, and octadecyl, di-, tri-, tetra-, penta-, and hexaglucosides and/ or galatoses. Suitable mixtures include coconut alkyl, di-, tri-, tetra-, and pentaglucosides and tallow alkyl tetra-, penta- and hexaglucosides. )

To prepare these compounds, the alcohol or alkylpolyethoxy alcohol is formed first and then reacted with glucose, or a source of glucose, to form the glucoside (attachment at the 1- position). The additional glycosyl units can then be attached between their 1-position and the preceding glycosyl units 2-,3-, 4- and/or 6-position, preferably predominantly the 2-position.

In the alkyl! polyglycosides, the alkyl moieties can be derived from the usual sources like fats, oils or chemically produced alcohols while their sugar moieties are created from hydrolyzed polysaccharides. Alkyl polyglycosides are the condensation product of fatty alcoho! and sugars like glucose with the number of glucose units defining the relative hydrophilicity. As discussed above, the sugar units can additionally be alkoxylated either before or after reaction with the fatty alcohols. Such alkyl polyglycosides are described in detail in WO 86/05199 for example.

Technical alkyl polyglycosides are generally not molecularly uniform products, but represent mixtures of alkyl groups and mixtures of monosaccharides and different oligosaccharides. Alkyl polyglycosides (also sometimes referred to as “APG's") are preferred for the purposes of the invention since they provide additional improvement in surface appearance relative to other surfactants. The glycoside moieties are preferably glucose moieties. The alkyl substituent is preferably a saturated or unsaturated alkyl moiety containing from about 8 to about 18 carbon atoms, preferably from about 8 to about 10 carbon atoms or a mixture of such alkyl moieties. Ce-

Y :

Cae alkyl polyglucosides are commercially available (e.g. Simusol® surfactants from Seppic

Corporation, 75 Quai d'Orsay, 75321 Paris, Cedex 7, France, and Glucopon®425 available from

Henkel). However, it has been found that purity of the alkyl polyglucoside can also impact performance, particularly end result for certain applications, including daily shower product

S technology. In the present invention, the preferred alkyl polyglucosides are those which have been purified enough for use in personal cleansing. Most preferred are “cosmetic grade” alkyl polyglucosides, particularly Cs to Cy alkyl polyglucosides, such as Plantaren 20009, Plantaren 2000 N®, and Piantaren 2000 N UP®, available from Henkel Corporation (Postfach 101100, D 40191 Dusseldorf, Germany). :

In the context of floor, counter, wall, etc. applications, another class of preferred nonionic surfactant is alkyl ethoxylates. The alkyl ethoxylates of the present invention are either linear or branched, and contain from about 8 carbon atoms to about 14 carbon atoms, and from about 4 ethylene oxide units to about 25 ethylene oxide units. Examples of alkyl ethoxylates include

Neodol® 91-6, Neodol 91-8® supplied by the Shell Corporation (P.O. Box 2463, 1 Shell Plaza,

Houston, Texas), and Alfonic® 810-60 supplied by Vista corporation, (300 Threadneedle P.O.

Box 19029, Houston, TX). More preferred surfactants are the alkyl ethoxylates comprising from : about 9 to about 12 carbon atoms, and from about 4 to about 8 ethylene oxide units. These surfactants offer excellent cleaning benefits and work synergistically with the required hydrophilic , polymers. A most preferred alkyl ethoxylate is C,,EQs, available from the Shell Chemical

Company under the trademark Neodol® 1-5. This surfactant is found to provide desirable wetting and cleaning properties, and can be advantageously combined with the preferred Cg. alkyl polyglucoside in a matrix that includes the wetting polymers of the present invention. While not wishing to be limited by theory, it is believed that the Cq.16 alkyl polyglucoside can provide a superior end result (i.e., reduce hazing) in compositions that additionally contain the preferred alkyl ethoxylate particularly when the preferred alkyl ethoxylate is required for superior cleaning.

The preferred the Cg4s alkyl polyglucoside is also found to improve perfume solubility of compositions comprising alky! ethoxylates. Higher levels of perfume can be advantageous for consumer acceptance.

The usage of liquid compositions according to the present invention are prepared with relatively low levels of active materials. Typically, compositions will comprise sufficient surfactant and optional solvent, as discussed hereinafter, to be effective as hard surface cleaners yet remain economical, accordingly they typically contain from about 0.005% to about 0.5% by weight of the composition of surfactant, preferably alkylpolyglycoside and/or Cg.4 alkylethoxylate surfactant, more preferably from about 0.01% to about 0.4% surfactant, and even more preferably from about 0.01% to about 0.3% surfactant. It has been found that use of low, rather than high levels of surfactant are advantageous to overall end result performance. It is also been found that when the primary surfactant system includes preferred alkyl ethoxylates that end result hazing is

. -. mitigated by specific cosurfactants. These preferred cosurfactants are Cs sulfonate and Poly-

Tergent CS-1, and are further described below in Section d.

Cc. Optional Organic Cleaning Solvent

The compositions, optionally, can also contain one, or more, organic cleaning solvents at } 5 effective levels, typically no less than about 0.25%, and, at least about 0.5%, preferably at least about 3.0%, and no more than about 7%, preferably no more than about 5%, by weight of the composition.

The surfactant provides cleaning and/ or wetting even without an organic cleaning solvent present. However, the cleaning can normally be further improved by the use of the right organic cleaning solvent. By organic cleaning solvent, it is meant an agent which assists the surfactant to remove soils such as those commonly encountered in the bathroom. The organic cleaning solvent also can participate in the building of viscosity, if needed, and in increasing the stability of the composition. The compositions containing Css alkyl polyglucosides and/or Ca 14 alkylethoxylates also have lower sudsing when the solvent is present. Thus, the suds profile can be controlled in large part by simply controlling the level of hydrophobic solvent in the formulation.

Such solvents typically have a terminal Ca-Cg hydrocarbon attached to from one to three ethylene glycol or propylene glycol moieties to provide the appropriate degree of hydrophobicity and, preferably, surface activity. Examples of commercially available hydrophobic cleaning : solvents based on ethylene glycol chemistry include mono-ethylene glycol n-hexyl ether (Hexyl

Cellosolve® available from Union Carbide). Examples of commercially available hydrophobic . cleaning solvents based on propylene glycol chemistry include the di-, and tri-propylene glycol derivatives of propyl and butyl alcohol, which are available from Arco Chemical (3801 West

Chester Pike, Newtown Square, PA 19073) and Dow Chemical (1691 N. Swede Road, Midland,

Michigan) under the trade names Arcosolv® and Dowanol®.

In the context of the present invention, preferred solvents are selected from the group consisting of mono-propylene glycol mono-propyl ether; di-propylene glycol mono-propyl ether; . mono-propylene glycol mono-butyl ether; di-propylene glycol mono-propyl ether; di-propylene glycol mono-buty! ether; tri-propylene glycol mono-butyl ether; ethylene glycol mono-butyi ether; di-ethylene glycol mono-butyl ether; ethylene glycol mono-hexyl ether; di-ethylene glycol mono- hexyl ether; and mixtures thereof. “Butyl” includes both normal butyl, isobutyl and tertiary butyl groups. Mono-propylene glycol and mono-propylene glycol mono-butyl ether are the most preferred cleaning solvent and are available under the tradenames Dowanol DPnP®and Dowanol

DPnB® from Dow Chemical. Di-propylene glycol mono-t-butyl ether is commercially available from Arco Chemical under the tradename Arcosolv PTB®,

The amount of organic cleaning solvent can vary depending on the amount of other ingredients present in the composition. The hydrophobic cleaning solvent is normally helpful in providing good cleaning, such as in floor cleaner applications.

oo . &

For cleaning in enclosed spaces, the solvent can cause the formation of undesirably small respirable droplets, so compositions/solutions for use in treating such spaces are desirably substantially free, more preferably completely free, of such solvents. d. Optional Additional Cosurfactant

The liquid compositions of the present invention optionally can include a small amount of additional cosurfactant such as anionic and/or nonionic detergent surfactant. Such anionic surfactants typically comprise a hydrophobic chain containing from about 8 to about 18 carbon atoms, preferably from about 8 to about 16 carbon atoms, and typically include a sulfonate or carboxylate hydrophilic head group. In general, the level of optional, e.g., anionic, cosurfactants in the compositions herein is from about 0.01% to about 0.25%, more preferably from about 0.01% to about 0.2%, most preferably from about 0.01% to about 0.1%, by weight of the composition.

In the context of floor, counter and other surface applications, the choice of cosurfactant can be critical in both selection of type and level. In compositions comprising Cs-Cis alkyl ethoxylates, it is found that low levels of Cg sulfonate can improve end result by providing a “toning” effect. By toning, it is meant an improvement in the visual appearance of the end result, due to less haziness. If present, the Cg sulfonate is preferably used in from about 1:10 to about - 1:1 weight ratio with respect to the primary surfactant(s). C, sulfonate is commercially available : ’ from Stepan under the tradename Bio-Terge PAS-8® as well as from the Witco Corporation under - the tradename Witconate NAS-8®. Another outstanding “toning” surfactant of benefit to the : 20 present invention is Poly-Tergent CS-1 which can be purchased from BASF. If present, the Poly- - Tergent CS-1 is preferably used in from about 1:20 to about 1:1 weight ratio with respect to the : primary surfactant(s). - Other surfactants which can be used, though less preferably, and typically at very low levels, include Cg-C45 alkyl sulfonates (Hostapur SAS® from Hoechst, Aktiengesellschaft, D-6230

Frankfurt, Germany), C45-C14 linear or branched alkyl benzene sulfonates, Cg-Cys alkyl ethoxy carboxylates detergent surfactant (Neodox® surfactants available from Shell Chemical

Corporation), Ci0.14 alkyl sulfates and ethoxysulfates (e.g., Stepanol AM® from Stepan). Alkyl! ethoxy carboxylates can be advantageously used at extremely low levels (about 0.01% or lower ) to dissolve perfume. This can be an important benefit given the low levels of active needed for the present invention to be most effective.

Alternative nonionic detergent surfactants for use herein are alkoxylated alcohols generally comprising from about 6 to about 16 carbon atoms in the hydrophobic alkyl chain of the alcohol. Typical alkoxylation groups are propoxy groups or propoxy groups in combination with ethoxy groups. Such compounds are commercially available under the tradename Antarox® available from Rhodia (P.O. Box 425 Cranberry, New Jersey 08512) with a wide variety of chain length and alkoxylation degrees. Block copolymers of ethylene oxide and propylene oxide can also be used and are available from BASF under the tradename Pluronic®. Preferred nonionic detergent surfactants for use herein are according to the formula R(X), H, were R is an alkyl chain having from about 6 to about 16 carbon atoms, preferably from about 8 to about 12 carbon atoms,

X is a propoxy, or a mixture of ethoxy and propoxy groups, n is an integer of from about 4 to . about 30, preferably from about 5 to about 8. Other non-ionic surfactants that can be used include those derived from natural sources such as sugars and include Cy-Cqs N-alkyl glucose amide surfactants. If present, the concentration of alternative nonionic surfactant is from about 0.01% to about 0.2%, more preferably from about 0.01% to about 0.1%, by weight of the composition. e. Mono- or Polycarboxylic Acid

For purposes of soap scum and hard water stain removal, the compositions can be made acidic with a pH of from about 2 to about 5, more preferably about 3. Acidity is accomplished, at least in part, through the use of one or more organic acids that have a pKa of less than about 5, preferably less than about 4. Such organic acids also can assist in phase formation for thickening, if needed, as well as provide hard water stain removal properties. It is found that organic acids are very efficient in promoting good hard water removal properties within the framework of the compositions of the present invention. Lower pH and use of one or more suitable acids is also found to be advantageous for disinfectancy benefits.

Examples of suitable mono-carboxylic acids include acetic acid, glycolic acid or 3-hydroxy ’ propionic acid and the like. Examples of suitable polycarboxylic acids include citric acid, tartaric acid, succinic acid, glutaric acid, adipic acid, and mixtures thereof. Such acids are readily . available in the trade. Examples of more preferred polycarboxylic acids, especially non-polymeric polycarboxylic acids, include citric acid (available from Aldrich Corporation, 1001 West Saint Paul

Avenue, Milwaukee, Wisconsin), a mixture of succinic, glutaric and adipic acids available from

DuPont (Wilmington, Delaware) sold as “refined AGS di-basic acids”, maleic acid (also available from Aldrich), and mixtures thereof. Citric acid is most preferred, particularly for applications requiring cleaning of soap scum. Glycolic acid and the mixture of adipic, glutaric and succinic acids provide greater benefits for hard water removal. The amount of organic acid in the compositions herein can be from about 0.01% to about 1%, more preferably from about 0.01% to about 0.5%, most preferably from about 0.025% to about 0.25% by weight of the composition. f. Odor Control Agents

As used herein, the term “cyclodextrin” includes any of the known cyclodextrins such as unsubstituted cyclodextrins containing from six to twelve glucose units, especially, alpha- cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin and/or their derivatives and/or mixtures thereof. The alpha-cyclodextrin consists of six glucose units, the beta-cyclodextrin consists of seven glucose units, and the gamma-cyclodextrin consists of eight glucose units arranged in donut-shaped rings. The specific coupling and conformation of the glucose units give the cyclodextrins rigid, conical molecular structures with hollow interiors of specific volumes. The "lining" of each internal cavity is formed by hydrogen atoms and glycosidic bridging oxygen atoms;

ES therefore, this surface is fairly hydrophobic. The unique shape and physical-chemical properties of the cavity enable the cyclodextrin molecules to absorb (form inclusion complexes with) organic molecules or parts of organic molecules which can fit into the cavity. Many odorous molecules can fit into the cavity including many malodorous molecules and perfume molecules. Therefore, cyclodextrins, and especially mixtures of cyclodextrins with different size cavities, can be used to control odors caused by a broad spectrum of organic odoriferous materials, which may, or may not, contain reactive functional groups. The complexation between cyclodextrin and odorous molecules occurs rapidly in the presence of water. However, the extent of the complex formation also depends on the polarity of the absorbed molecules. In an aqueous solution, strongly hydrophilic molecules (those which are highly water-soluble) are only partially absorbed, if at all.

Therefore, cyclodextrin does not complex effectively with some very low molecular weight organic amines and acids when they are present at low levels on wet surfaces. As the water is being removed however, e.g., the surface is being dried off, some low molecular weight organic amines and acids have more affinity and will complex with the cyclodextrins more readily.

The cavities within the cyclodextrin in the solution of the present invention should remain essentially unfilled (the cyclodextrin remains uncomplexed) while in solution, in order to allow the cyclodextrin to absorb various odor molecules when the solution is applied to a surface. Non- , . derivatised (normal) beta-cyclodextrin can be present at a level up to its solubility limit of about 1.85% (about 1.859 in 100 grams of water) at room temperature. Beta-cyclodextrin is not preferred in compositions which call for a level of cyclodextrin higher than its water solubility limit.

Non-derivatised beta-cyclodextrin is generally not preferred when the composition contains surfactant since it affects the surface activity of most of the preferred surfactants that are compatible with the derivatised cyclodextrins.

Preferably, the aqueous cleaning solution of the present invention is clear. The term "clear" as defined herein means transparent or translucent, preferably transparent, as in "water clear,” when observed through a layer having a thickness of less than about 10 cm.

Preferably, the cyclodextrins used in the present invention are highly water-soluble such as, alpha-cyclodextrin and/or derivatives thereof, gamma-cyclodextrin and/or derivatives thereof, derivatised beta-cyclodextrins, and/or mixtures thereof. The derivatives of cyclodextrin consist mainly of molecules wherein some of the OH groups are converted to OR groups. Cyclodextrin : derivatives include, e.g., those with short chain alkyl groups such as methylated cyclodextrins, and ethylated cyclodextrins, wherein R is a methyl or an ethyl group; those with hydroxyalkyl substituted groups, such as hydroxypropyl cyclodextrins and/or hydroxyethyl cyclodextrins, wherein R is a -CHy-CH(OH)-CH3 or a “CH2CH»-OH group; branched cyclodextrins such as maltose-bonded cyclodextrins; cationic cyclodextrins such as those containing 2-hydroxy-3- (dimethylamino)propyl ether, wherein R is CHo-CH(OH)-CH2-N(CH3)o which is cationic at low pH; quaternary ammonium, e.g., 2-hydroxy-3-(trimethylammonio)propyl ether chloride groups,

wherein R is CHp-CH(OH)-CH>-N*(CH3)3CI; anionic cyclodextrins such as carboxymethyl cyclodextrins, cyclodextrin sulfates, and cyclodextrin succinylates; amphoteric cyclodextrins such as carboxymethyl/quaternary ammonium cyclodextrins; cyclodextrins wherein at least one : glucopyranose unit has a 3-6-anhydro-cyclomalto structure, e.g, the mono-3-6- anhydrocyclodextrins, as disclosed in "Optimal Performances with Minimal Chemical Modification of Cyclodextrins”, F. Diedaini-Pilard and B. Perly, The 7th International Cyclodextrin Symposium

Abstracts, April 1994, p. 49, said references being incorporated herein by reference: and mixtures thereof. Other cyclodextrin derivatives are disclosed in U.S. Pat. Nos.: 3,426,011, Parmerter et al, issued Feb. 4, 1969; 3,453,257; 3,453,258; 3,453,259; and 3,453,260, all in the names of

Parmerter et al., and all issued July 1, 1969; 3,459,731, Gramera et al., issued Aug. 5, 1969; 3,553,191, Parmerter et al., issued Jan. 5, 1971; 3,565,887, Parmerter et al., issued Feb. 23, 1971; 4,635,152, Szejtii et al., issued Aug. 13, 1985; 4,616,008, Hirai et al., issued Oct. 7, 1986; 4,678,598, Ogino et al., issued Jul. 7, 1987; 4,638,058, Brandt et al., issued Jan. 20, 1987; and 4,746,734, Tsuchiyama et al., issued May 24, 1988; all of said patents being incorporated herein by reference.

Highly water-soluble cyclodextrins are those having water solubility of at least about 10 ga in 100 ml of water at room temperature, preferably at least about 20 g in 100 ml of water, more preferably at least about 25 g in 100 ml of water at room temperature. The availability of solubilized, uncomplexed cyclodextrins is essential for effective and efficient odor control performance. Solubilized, water-soluble cyclodextrin can exhibit more efficient odor control performance than non-water-soluble cyclodextrin when deposited onto surfaces.

Examples of preferred water-soluble cyclodextrin derivatives suitable for use herein are hydroxypropyl alpha-cyclodextrin, methylated alpha-cyclodextrin, methylated beta-cyclodextrin, hydroxyethyl beta-cyclodextrin, and hydroxypropyl beta-cyclodextrin. Hydroxyalkyl cyclodextrin derivatives preferably have a degree of substitution of from about 1 to about 14, more preferably from about 1.5 to about 7, wherein the total number of OR groups per cyclodextrin is defined as the degree of substitution. Methylated cyclodextrin derivatives typically have a degree of substitution of from about 1 to about 18, preferably from about 3 to about 16. A known methylated beta-cyclodextrin is heptakis-2,6-di-O-methyi-B-cyclodextrin, commonly known as

DIMEB, in which each glucose unit has about 2 methyl groups with a degree of substitution of about 14. A preferred, more commercially available, methylated beta-cyclodextrin is a randomly methylated beta-cyclodextrin, commonly known as RAMEB, having different degrees of substitution, normally of about 12.6. RAMEB is more preferred than DIMEB, since DIMEB affects the surface activity of the preferred surfactants more than RAMEB. The preferred cyclodextrins are available, e.g., from Cerestar USA, Inc. and Wacker Chemicals (USA), Inc.

It is also preferable to use a mixture of cyclodextrins. Such mixtures absorb odors more broadly by complexing with a wider range of odoriferous molecules having a wider range of molecular sizes. Preferably at least a portion of the cyclodextrin is alpha-cyclodextrin and/or its

. . & : derivatives, gamma-cyclodextrin and/or its derivatives, and/or derivatised beta-cyclodextrin, more preferably a mixture of alpha-cyclodextrin, or an alpha-cyclodextrin derivative, and derivatised beta-cyclodextrin, even more preferably a mixture of derivatised alpha-cyclodextrin and derivatised beta-cyclodextrin, most preferably a mixture of hydroxypropyl alpha-cyclodextrin and hydroxypropyl beta-cyclodextrin, andlor a mixture of methylated alpha-cyclodextrin and methylated beta-cyclodextrin.

It is preferable that the usage compositions of the present invention contain low levels of cyclodextrin so that no visible residue appears at normal usage levels. Preferably, the solution used to treat the surface under usage conditions is virtually not discernible when dry. Typical levels of cyclodextrin in usage compositions for usage conditions are from about 0.01% to about 1%, preferably from about 0.05% to about 0.75%, more preferably from about 0.1% to about 0.5% by weight of the composition. Compositions with higher concentrations can leave unacceptable visible residues. g. Optional Source of Peroxide

The compositions of the invention can contain peroxide such as hydrogen peroxide, or a source of hydrogen peroxide, for further disinfectancy, fungistatic and fungicidal benefits. The a components of the present composition are substantially compatible with the use of peroxides. i : Preferred peroxides include benzoyl peroxide and hydrogen peroxide. These can optionally be i present-in the compositions herein in levels of from about 0.05% to about 5%, more preferably ; 20 from about 0.1% to about 3%, most preferably from about 0.2% to about 1.5%. i When peroxide is present, it is desirable to provide a stabilizing system. Suitable

Li stabilizing systems are known. A preferred stabilizing system consists of radical scavengers o and/or metal chelants present at levels of from about 0.01% to about 0.5%, more preferably from : about 0.01% to about 0.25%, most preferably from about 0.01% to about 0.1%, by weight of the composition. Examples of radical scavengers include anti-oxidants such as propyl gallate, butylated hydroxy toluene (BHT), butylated hydroxy anisole (BHA) and the like. Examples of suitable metal chelants include diethylene triamine penta-acetate, diethylene triamine penta- methylene phosphonate, hydroxyethyl diphosphonate and the like. h. Optional Thickening Polymer:

Low levels of polymer can also be used to thicken the preferred aqueous compasitions of the present invention. To the extent a given polymer can be considered a hydrophilic polymer or a thickening polymer, such polymer shall be considered a hydrophilic polymer for purposes of the present invention. In general, the leve! of thickening polymer is kept as low as possible so as not to hinder the product's end result properties. Xanthan gum is a particularly preferred thickening agent as it can also enhance end result properties, particularly when used in low concentrations.

The thickening polymer agent is present in from about 0.001% to about 0.1%, more preferably from about 0.0025% to about 0.05%, most preferably from about 0.005% to about 0.025%, by weight of the composition.

i. Aqueous Solvent System

The compositions which are aqueous, comprise at least about 80% aqueous solvent by weight of the composition, more preferably from about 80% to over 99% by weight of the composition. The aqueous compositions are typically in micellar form, and do not incorporate substantial levels of water insoluble components that induce significant micellar swelling.

The aqueous solvent system can also comprise, in addition to water, low molecular weight, highly water-soluble solvents typically found in detergent compositions, e.g., ethanol, isopropanol, etc. These solvents can be used to provide disinfectancy properties to compositions that are otherwise low in active. Additionally, they can be particularly useful in compositions wherein the total level of perfume is very low. In effect, highly volatile soivents can provide “lift”, and enhance the character of the perfume. Highly volatile solvents, if present are typically present in from about 0.256% to about 5%, more preferably from about 0.5% to about 3%, most preferably from about 0.5% to about 2%, by weight of the composition. Examples of such solvents include methanol, ethanol, isopropanol, n-butanol, iso-butanol, 2-butanol, pentanol, 2- methyl-1-butanol, methoxymethanol, methoxyethanol, methoxy propanol, and mixtures thereof.

The compositions of the present invention can also include other solvents, and in particular paraffins and isoparaffins, which can substantially reduce the suds created by the composition. . i. Optional Suds Suppressor

Suitable silicone suds suppressors for use herein include any silicone and silica-silicone mixtures. Silicones can be generally represented by alkylated polysiloxane materials while silica is normally used in finely divided forms exemplified by silica aerogels and xerogels and hydrophobic silicas of various types. In industrial practice, the term "silicone" has become a generic term which encompasses a variety of relatively high-molecular-weight polymers : 25 containing siloxane units and hydrocarbyl groups of various types. Indeed, silicone compounds have been extensively described in the art, see for instance United States Patents: US 4,076,648; US 4,021,365; US 4,749,740; US 4,983,316 and European Patents: EP 150,872; EP 217,501; and EP 499,364, all of said patents being incorporated herein by reference. Preferred are polydiorganosiloxanes such as polydimethylsiloxanes having trimethylsiiyl end blocking units and having a viscosity at 25°C of from 5 x 10-5 m2/s to 0.1 mZ/s, i.e. a value of n in the range 40 to 1500. These are preferred because of their ready availability and their relatively low cost.

A preferred type of silicone compounds useful in the compositions herein comprises a mixture of an alkylated siloxane of the type hereinabove disclosed and solid silica. The solid silica can be a fumed silica, a precipitated silica or a silica made by the gel formation technique.

The silica particles can be rendered hydrophobic by treating them with diakylsilyl groups and/or trialkylsilane groups either bonded directly onto the silica or by means of silicone resin. A preferred silicone compound comprises a hydrophobic silanated, most preferably trimethylsilanated silica having a particle size in the range from 10 mm to 20 mm and a specific

EN surface area above 50 m2/g. Silicone compounds employed in the compositions according to the present invention suitably have an amount of silica in the range of 1 to 30% (more preferably 2.0 to 15%) by weight of the total weight of the silicone compounds resulting in silicone compounds having an average viscosity in the range of from 2 x 104m2/s to 1m?2/s. Preferred silicone compounds can have a viscosity in the range of from 5 x 10-3m2/s to 0.1m?/s.

Particularly suitable are silicone compounds with a viscosity of 2 x 10"2m2/s or 4.5 x 10-2m2Js,

Suitable silicone compounds for use herein are commercially available from various companies including Rhone Poulenc, Fueller and Dow Corning. Examples of silicone compounds for use herein are Silicone DB® 100 and Silicone Emulsion 2-3597® both commercially available from Dow Coming. k. Optional Perfume and/or Additional Adjuvants

Optional components, such as perfumes and/or other conventional adjuvants can also be incorporated in the present compositions.

Perfume

An optional, but highly preferred ingredient, is a perfume, usually a mixture of perfume ingredients. As used herein, perfume includes constituents of a perfume which are added primarily for their olfactory contribution, often complimented by use of a volatile organic solvent such as ethanol.

Most hard surface cleaner products contain some perfume to provide an olfactory : 20 aesthetic benefit and to cover any "chemical" odor that the product may have. The main function of a small fraction of the highly volatile, low boiling (having low boiling points), perfume } components in these perfumes is to improve the fragrance odor of the product itself, rather than ) impacting on the subsequent odor of the surface being cleaned. However, some of the less volatile, high boiling perfume ingredients can provide a fresh and clean impression to the 25 surfaces, and it is sometimes desirable that these ingredients be deposited and present on the dry surface.

The perfumes are preferably those that are more water-soluble and/or volatile to minimize spotting and filming. The perfumes useful herein are described in more detail in U.S. Patent 5,108,660, Michael, issued April 28, 1992, at col. 8 lines 48 to 68, and col. 9 lines 1 to 68, and col. 30 10 lines 1 to 24, said patent, and especially said specific portion, being incorporated by reference.

Perfume components can be natural products such as essential oils, absolutes, resinoids, resins, concretes, etc., and/or synthetic perfume components such as hydrocarbons, alcohols, aldehydes, ketones, ethers, acids, acetals, ketals, nitriles, and the like, including saturated and unsaturated compounds, aliphatic, carbocyclic and heterocyclic compounds. Examples of such 35 perfume components are: geraniol, geranyl acetate, linalool, linalyl acetate, tetrahydrolinalool, citronellol, citronellyl acetate, dihydromyrcenol, dihydromyrcenyl acetate, terpineol, terpinyl acetate, acetate, 2-phenylethanol, 2-phenylethyl acetate, benzyl alcohol, benzyl acetate, benzyl salicylate, benzyl benzoate, styrallyl acetate, amyl salicylate, dimenthylbenzylcarbinol,

Compositions herein typically comprise from 0.1% to 2% by weight of the total composition of a perfume ingredient, or mixtures thereof, preferably from 0.1% to 1%. In the case of the preferred embodiment containing peroxide, the perfumes must be chosen so as to be compatible with the oxidant.

In a preferred execution, the perfume ingredients are hydrophobic and highly volatile, e.g., ingredients having a boiling point of less than about 260°C, preferably less than about . 255°C; and more preferably less than about 250°C, and a ClogP of at least about 3, preferably more than about 3.1, and even more preferably more than about 3.2.

The logP of many ingredients has been reported; for example, the Pomona92 database, ) available from Daylight Chemical Information Systems, inc. (Daylight CIS), Irvine, California, contains many, along with citations to the original literature. However, the logP values are most conveniently calculated by the "CLOGP" program, also available from Daylight CIS. This program also lists experimental logP values when they are available in the Pomona92 database. The "calculated iogP" (ClogP) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C.

A. Ramsden, Eds., p. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment approach is based on the chemical structure of each ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding. The ClogP values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental logP values in the selection of the principal solvent ingredients which are useful in the present invention. Other methods that can be used to compute ClogP include, e.g., Crippen's fragmentation method as disclosed in J. Chem. Inf.

Comput. Sci. 27, 21 (1987); Viswanadhan's fragmentation method as disclose in J. Chem. Inf.

Comput. Sci., 29, 163 (1989); and Broto's method as disclosed in Eur. J. Med. Chem. - Chim.

Theor., 19, 71 (1984).

Other Adjuvants

>

The compositions herein can comprise a variety of other optional ingredients, including further actives and detergent builder, as well as primarily aesthetical ingredients.

In particular the rheology of the compositions herein can be made suitable for suspending particles in the composition, e.g., particles of abrasives. Detergency Builders

Detergent builders that are efficient for hard surface cleaners and have reduced filming/streaking characteristics at the critical levels are another optional ingredient. Preferred detergent builders are the carboxylic acid detergent builders described hereinbefore as part of the polycarboxylic acid disclosure, including citric and tartaric acids. Tartaric acid improves cleaning and can minimize the problem of filming/streaking that usually occurs when detergent builders are added to hard surface cleaners.

The detergent builder is present at levels that provide detergent building, and, those that are nat part of the acid pH adjustment described hereinbefore, are typically present at a level of from about 0.01% to about 0.3%, more preferably from about 0.005% to about 0.2%, and most preferably from about 0.05% to about 0.1%, by weight of the composition.

Buffers

The compositions herein can also contain other various adjuncts such as buffers, - + preservatives, and antibacterial agents, which are known to the art for detergent compositions. ¢ Preferably they are not used at levels that cause unacceptable filming/streaking. Buffers are an important class of adjuncts in the present compositions. This occurs mainly as a result of the low levels of active employed. An ideal buffer system will maintain pH over a desired narrow range, while nat leading to streaking/filming issues. Preferred buffers in the context of the invention are those which are highly volatile, yet can provide cleaning benefits in use. As such, they are advantageous in that they can be used at higher levels than corresponding buffers that are less volatile. Such buffers tend to have low molecular weight, i.e., less than about 150 g/mole and generally contain no more than one hydroxy group. Examples of preferred buffers include ammonia, methanol amine, ethanol amine, 2-amino-2-methyl-1-propanol, 2-dimethylamino-2- methyl-1-propanol, acetic acid, glycolic acid, and the like. Most preferred among these are ammonia, 2-dimethylamino-2-methyl-1-propanol, and acetic acid. When used, these buffers are typically present at levels of from about 0.005% to about 0.5%, by weight of the composition, with the higher levels being more preferred for the more volatile buffer materials.

Non-volatile buffers can also be used in this invention. Such buffers are used at generally lower levels than the preferred levels because of increased streaking/filming tendencies.

Examples of such buffers include, but are not limited to, sodium carbonate, potassium carbonate and bicarbonate, 1,3-bis(aminomethyl) cyclohexane, sodium citrate, citric acid, maleic acid, tartaric acid, and the like. Maleic acid is particularly preferred as a buffer because of its tendency not to induce surface damage. Citric acid is also desirable since it provides anti-microbial benefits as a registered EPA active. Additionally, in compositions comprising the hydrophilic polymers of the present invention for daily shower applications, acidity has been found to promote better wetting and provide longer lasting “sheeting” effects. When used, non-volatile buffers are present in from about 0.001% to about 0.05% by weight of the composition.

Non-limiting examples of other adjuncts are: enzymes such as proteases; hydrotropes such as sodium toluene sulfonate, sodium cumene sulfonate, and potassium xylene sulfonate; and aesthetic-enhancing ingredients such as colorants, providing they do not have an adverse impact on filming/streaking.

Preservatives and Antibacterial Agents

Preservatives can also be used, and may be required in many of the compositions of the present invention, since they contain high levels of water. Examples of preservatives include bronopol, hexitidine sold by Angus chemical (211 Sanders Road, Northbrook, Illinois, USA).

Other preservatives include Kathon®, 2-((hydroxymethyl) (amino)ethanol, propylene glycol, sodium hydroxymethyl amino acetate, formaldehyde and glutaraldehyde, dichloro-s-triazinetrione, trichloro-s-triazinetrione, and quaternary ammonium salts including dioctyl dimethyl ammonium chloride, didecyl dimethyl ammonium chloride, Cq;, C14 and Cig dimethyl benzyl. Preferred preservatives include 1,2-benzisothiazolin-3-one and polyhexamethylene biguanide sold by Avicia

Chemicals (Wilmington, Delaware 19897), chlorhexidine diacetate sold by Aldrich-Sigma (1001

West Saint Paul Avenue, Milwaukee, WI 53233), and sodium pyrithione sold by Arch Chemicals ) (501 Merritt Seven, P.O. Box 5204, Norwalk CT 06856). When used, preservatives are preferentially present at concentrations of from about 0.0001% to about 0.01%. These same ] preservatives can function to provide antibacterial control on the surfaces, but typically will require use at higher levels from about 0.005 to about 0.1%. Other antibacterial agents, including quaternary ammonium salts, can be present, but are not preferred in the context of the present invention at high levels, i.e., at levels greater than about 0.05%. Such compounds have been : 25 found to often interfere with the benefits of the preferred polymers. In particular, quaternary ammonium surfactants tend to hydrophobically modify hard surfaces. Thus, the preferred polymers are found to be ineffective in compositions comprising significant concentrations of quaternary ammonium surfactants. Similar results have been found using amphoteric surfactants, including lauryl betaines and coco amido betaines. When present, the level of cationic or amphoteric surfactant should be at levels below about 0.1%, preferably below about 0.05%. More hydrophobic antibacterial/germicidal agents, like orthobenzyl-para-chlorophenol, are to be avoided. If present, such materials should be kept at levels below about 0.05%.

A “Daily Shower” Compositions

Compositions for use in the bathroom and/or shower on a regular basis provide the benefit of maintaining cleanliness and appearance rather than having to remove large amounts of built-up soil.

&

The ingredients in these “daily shower” compositions are selected so as to avoid the appearance of spotsffilms on the treated surface, even when the surface is not rinsed or wiped completely to a dry state. For stress conditions, the selection of both a polyvinylpyridine amine oxide, or polyvinylpyridine polymer, and a preferred primary detergent surfactant, such as an alkyl polysaccharide detergent surfactant, are required for optimum appearance.

B. Glass Cleaner Compositions

Glass cleaner compositions typically contain less materials than other compositions, since glass composition residues are more easily seen. For these compositions, only the optimal polymers and surfactants, and methods which provide at least some rubbing action, are required.

Glass cleaner compositions comprise: a. an effective amount to reduce the contact angle and/or increase surface hydrophilicity, up to about 0.5%, preferably from about 0.005% to about 0.4%, more preferably from about 0.01% to about 0.3%, by weight of the composition, of hydrophilic polymer, preferably substantive, that renders the treated surface hydrophilic, and preferably is a polymer selected from the group consisting of: polystyrene sulfonate; polyvinyl pyrrolidone; polyvinyl pyrrolidone acrylic acid : copolymer; polyvinyl pyrrolidone acrylic acid copolymer sodium salt; polyvinyl : : pyrrolidone acrylic acid copolymer potassium salt; polyvinyl pyrrolidone- vinyl imidazoline; polyvinyl pyridine; polyvinyl pyridine n-oxide; and mixtures thereof; and more preferably polyvinyl pyridine n-oxide; b. an effective amount of primary detergent surfactant, preferably from about 0.001% to about 0.5%, more preferably from about 0.005% to about 0.3%, most preferably from a about 0.025% to about 0.3%, by weight of the composition, said primary detergent surfactant preferably comprising as the primary surfactant, alkyl polysaccharide detergent surfactant having an alkyl group containing from about 8 to about 18 carbon atoms, more preferably from about 8 to about 16 carbon atoms, the alkyi distribution wherein at least about 50% of the chainlength mixture comprises from about 10 carbon atoms to about 16 carbon atoms, optionally, as the primary surfactant, but preferably as the cosurfactant, a minor amount that is less than the amount of primary surfactant, e.g., from about 0.0001% to about 0.3%, preferably from about 0.001% to about 0.2%, more preferably from about 0.05% to about 0.2%, of cosurfactant; c. optionally, an effective amount to provide increased cleaning, e.g., from about 0.5% to about 7%, preferably from about 0.5% to about 5%, more preferably from about 0.5% to about 3%, of one or more organic cleaning solvents, preferably selected from the group consisting of: mono-propylene glycol mono-propyl ether; mono-propylene glycol mono-butyl ether; di-propylene glycol mono-propyl ether; di-propylene glycol mono-butyl ether; di-propylene glycol mono-butyl ether; tri-propylene glycol mono-

Glass cleaning compositions comprising the polymers of the present invention can be used as a spray execution, and with one or more substrates, including rags, cloths, or paper towels. In such a context, it has been found that some of the preferred polymers, such as polyvinyl amine oxides provide anti-fog benefits. It is believed that the hygroscopic properties of the preferred polymers are responsible for the benefits. . C. General Purpose and Conventional Floor Cleaning Compositions

D. Wet Wipes for Glass and Shiny Surfaces, Floors, Counter Walls and Other Surfaces

The glass cleaning compositions described in Section B. above and General Purpose and

Floor compositions described in Section C. above can be used in a pre-moistened wipe. The wipe substrate can be composed of suitable unmodified and/or modified naturally occurring fibers including cotton, Esparto grass, bagasse, hemp, flax, silk, wool, wood pulp, chemically modified wood pulp, jute, ethyl cellulose, and/or cellulose acetate. Suitable synthetic fibers can comprise . fibers of one, or more, of polyvinyl chloride, polyvinyl fluoride, polytetrafluoroethylene, polyvinylidene chloride, polyacrylics such as ORLON®, polyvinyl acetate, Rayon®, polyethylvinyl acetate, non-soluble or soluble polyvinyl alcohol, polyolefins such as polyethylene (e.g.,

PULPEX®) and polypropylene, polyamides such as nylon, polyesters such as DACRON® or

KODEL®, polyurethanes, polystyrenes, and the like, including fibers comprising polymers containing more than one monomer. The absorbent layer can comprise solely naturally occurring fibers, solely synthetic fibers, or any compatible combination of naturally occurring and synthetic fibers.

The fibers useful herein can be hydrophilic, hydrophobic, or can be a combination of both hydrophilic and hydrophobic fibers. As indicated above, the particular selection of hydrophilic or ’ hydrophobic fibers depends upon the other materials included in the absorbent (and to some degree) the scrubbing layer described hereinafter. Suitable hydrophilic fibers for use in the ) present invention include cellulosic fibers, modified cellulosic fibers, rayon, cotton, polyester fibers such as hydrophilic nylon (HYDROFIL®). Suitable hydrophilic fibers can also be obtained by hydrophilizing hydrophobic fibers, such as surfactant-treated or silica-treated thermoplastic fibers derived from, for example, polyolefins such as polyethylene, polypropylene, polyacrylics, polyamides, polystyrenes, polyurethanes and the like.

Suitable wood pulp fibers can be obtained from well-known chemical processes such as the Kraft and sulfite processes. It is especially preferred to derive these wood pulp fibers from southern soft woods due to their premium absorbency characteristics. These wood pulp fibers can also be obtained from mechanical processes, such as ground wood, refiner mechanical, thermomechanical, chemimechanical, and chemi-thermomechanical pulp processes. Recycled or secondary wood pulp fibers, as well as bleached and unbleached wood pulp fibers, can be used.

Another type of hydrophilic fibers for use in the present invention are chemically stiffened cellulosic fibers. As used herein, the term "chemically stiffened cellulosic fibers" means cellulosic fibers that have been stiffened by chemical means to increase the stiffness of the fibers under both dry and aqueous conditions. Such means can include the addition of a chemical stiffening agent that, for example, coats and/or impregnates the fibers. Such means can also include the stiffening of the fibers by altering the chemical structure, e.g., by crosslinking polymer chains.

Where fibers are used as the absorbent layer (or a constituent component thereof), the fibers can optionally be combined with a thermoplastic material. Upon melting, at least a portion of this thermoplastic material migrates to the intersections of the fibers, typically due to interfiber capillary gradients. These intersections become bond sites for the thermoplastic material. When cooled, the thermoplastic materials at these intersections solidify to form the bond sites that hold the matrix or substrate of fibers together in each of the respective layers. This can be beneficial in providing additional overall integrity to the cleaning wipe.

Amongst its various effects, bonding at the fiber intersections increases the overall compressive modulus and strength of the resulting thermally bonded member. In the case of the chemically stiffened cellulosic fibers, the melting and migration of the thermoplastic material also has the effect of increasing the average pore size of the resultant substrate, while maintaining the density and basis weight of the substrate as originally formed. This can improve the fluid acquisition properties of the thermally bonded substrate upon initial exposure to fluid, due to improved fluid permeability, and upon subsequent exposure, due to the combined ability of the stiffened fibers to retain their stiffness upon wetting and the ability of the thermoplastic material to remain bonded at the fiber intersections upon wetting and upon wet compression. In net, : thermally bonded substrates of stiffened fibers retain their original overall volume, but with the : volumetric regions previously occupied by the thermoplastic material becoming open to thus . increase the average interfiber capillary pore size.

Thermoplastic materials useful in the present invention can be in any of a variety of forms : including particulates, fibers, or combinations of particulates and fibers. Thermoplastic fibers are a particularly preferred form because of their ability to form numerous interfiber bond sites.

Suitable thermoplastic materials can be made from any thermoplastic polymer that can be melted at temperatures that will not extensively damage the fibers that comprise the primary substrate or matrix of each layer. Preferably, the melting point of this thermoplastic material will be less than about 190°C, and preferably between about 75°C and about 175°C. In any event, the melting point of this thermoplastic material should be no lower than the temperature at which the thermally bonded absorbent structures, when used in the cleaning pads, are likely to be stored. The melting point of the thermoplastic material is typically no lower than about 50°C.

The thermoplastic materials, and in particular the thermoplastic fibers, can be made from a variety of thermoplastic polymers, including polyolefins such as polyethylene (e.g., PULPEX®) and polypropylene, polyesters, copolyesters, polyvinyl acetate, polyethylvinyl acetate, polyvinyl chloride, polyvinylidene chloride, polyacrylics, polyamides, copolyamides, polystyrenes, polyurethanes and copolymers of any of the foregoing such as vinyl chloride/viny! acetate, and the like. Depending upon the desired characteristics for the resulting thermally bonded absorbent member, suitable thermoplastic materials include hydrophobic fibers that have been made hydrophilic, such as surfactant-treated or silica-treated thermoplastic fibers derived from, for example, polyolefins such as polyethylene or polypropylene, polyacrylics, polyamides,

polystyrenes, polyurethanes and the like. The surface of the hydrophobic thermoplastic fiber can be rendered hydrophilic by treatment with a surfactant, such as a nonionic or anionic surfactant, e.g., by spraying the fiber with a surfactant, by dipping the fiber into a surfactant or by including the surfactant as part of the polymer melt in producing the thermoplastic fiber. Upon melting and resolidification, the surfactant will tend to remain at the surfaces of the thermoplastic fiber.

Suitable surfactants include nonionic surfactants such as Brij® 76 manufactured by [IC] Americas,

Inc. of Wilmington, Delaware, and various surfactants sold under the Pegosperse® trademark by

Glyco Chemical, Inc. of Greenwich, Connecticut. Besides nonionic surfactants, anionic surfactants can also be used. These surfactants can be applied to the thermoplastic fibers at levels of, for example, from about 0.2 to about 1 gram per square centimeter of thermoplastic fiber.

Suitable thermoplastic fibers can be made from a single polymer (monocomponent fibers), or can be made from more than one polymer (e.g., bicomponent fibers). As used herein, "bicomponent fibers” refers to thermoplastic fibers that comprise a core fiber made from one polymer that is encased within a thermopiastic sheath made from a different polymer. The polymer comprising the sheath often melts at a different, typically lower, temperature than the polymer comprising the core. As a result, these bicomponent fibers provide thermal bonding due to melting of the sheath polymer, while retaining the desirable strength characteristics of the core ) polymer.

Suitable bicompanent fibers for use in the present invention can include sheath/core fibers having the following polymer combinations: polyethylene/ polypropylene, poiyethylvinyl acetate/polypropylene, polyethylene/polyester, polypropylene/polyester, copolyester/polyester, and the like. Particuiarly suitable bicomponent thermoplastic fibers for use herein are those having a polypropylene or polyester core, and a lower melting copolyester, polyethylvinyl acetate or polyethylene sheath (e.g., those available from Danaklon a/s, Chisso Corp., and CELBOND®, available from Hercules). These bicomponent fibers can be concentric or eccentric. As used herein, the terms "concentric" and "eccentric" refer to whether the sheath has a thickness that is even, or uneven, through the cross-sectional area of the bicomponent fiber. Eccentric bicomponent fibers can be desirable in providing more compressive strength at lower fiber thicknesses.

Methods for preparing thermally bonded fibrous materials are described in U.S. application Serial No. 08/479,096 (Richards et al.), filed July 3, 1995 (see especially pages 16-20) and U.S. Patent 5,549,589 (Horney et al.), issued August 27, 1996 (see especially Columns 9 to 10). The disclosures of both of these references are incorporated herein by reference.

The absorbent layer can also comprise a HIPE-derived hydrophilic, polymeric foam. Such foams and methods for their preparation are described in U.S. Patent 5,550,167 (DesMarais), issued August 27, 1996; and commonly assigned U.S. patent application Serial No. 08/370,695 (Stone et al}, filed January 10, 1995 (both of which are incorporated herein by reference).

The wipe can consist of one or more layers including an optional scrub layer for maximum cleaning efficiency. For pre-moistened wipes that use a single substrate, the substrate preferably contains fibers comprising of some combination of hydrophilic and hydrophobic fibers, and more preferably fibers comprising at least about 30% hydrophobic fibers and even more preferably at least about 50% of hydrophobic fibers in a hydroentangled substrate. The term “hydrophobic fibers” includes polyester fibers as well as fibers derived from polyolefins such as polyethylene, polypropylene, and the like. The combination of hydrophobic fibers and absorbent hydrophilic fibers represents a particularly preferred embodiment for the single substrate pre-moistened wipe since the absorbent hydrophilic fibers, typically cellulose, aid in the sequestering and removal of dust and other soils present on the surface. The hydrophobic fibers are particularly useful in cleaning greasy soils, in improving the pre-moistened wipe and in lowering the friction between substrate and hard surface (glide). In terms of rank ordering of fiber composition for improved glide, the inventors have found polyester fibers, particularly polyester fibers in combination with polypropylene fibers, to be most effective in providing excellent glide, followed by polyethylene fibers. Cellulose (or rayon) based pre-moistened wipes, though highly absorbent, lead to significant friction between substrate and surface to be cleaned. Fiber blends are more difficult to rank order for providing excellent glide, though it has been found that even low levels of polyester . or polypropylene fiber content can significantly improve the glide performance in virtually all cases. Fiber compositions that typically have a coefficient of friction with glass can be improved, as needed, by impregnating or chemically bonding the wipe with low levels of silicone or other ’ chemicals that are known to reduce friction. Silicones are preferred since they also reduce composition sudsing, leading to improved result.

Various forming methods can be used to form a suitable fibrous substrate for the premoistened wipes of the present invention. For instance, the substrate can be made by nonwoven dry forming techniques, such as air-laying, or alternatively by wet laying, such as on a paper-making machine. Other non-woven manufacturing techniques, including but not limited to techniques such as melt blown, spunbonded, needle punched, and hydroentanglement methods, can also be used.

In one embodiment, the dry fibrous substrate can be an airlaid nonwoven substrate comprising a combination of natural fibers, staple length synthetic fibers, and a latex binder. The dry fibrous substrate can be from about 20% to about 80%, by weight, of wood pulp fibers, from about 10% to about 60%, by weight, of staple length polyester fibers, and from about 10% to about 25%, by weight, of binder.

The dry, fibrous substrate can have a basis weight of between about 30 and about 100 grams per square meter. The density of the dry substrate can be measured after evaporating the liquid from the premoistened wipe, and the density can be less than about 0.15 grams per cubic centimeter. The density is the basis weight of the dry substrate divided by the thickness of the dry substrate, measured in consistent units, and the thickness of the dry substrate is measured using a circular load foot having an area of about 2 square inches and which provides a confining pressure of about 95 grams per square inch. In one embodiment, the dry substrate can have a basis weight of about 64 grams per square meter, a thickness of about 0.06 cm, and a density of about 0.11 grams per cubic centimeter.

In one embodiment, the dry fibrous substrate can comprise at least about 50 percent, by weight, of wood pulp fibers, and more preferably at least about 70 percent by weight wood pulp fibers. One particular airlaid nonwoven substrate which is suitable for use in the present invention comprises about 73.5 percent by weight cellulosic fibers (Southern softwood Kraft having an average fiber length of about 2.6 mm); about 10.5 percent by weight polyester fibers having a denier of about 1.35 gram/9000 meter of fiber length and a staple length of about 0.85 inch; and -about 16 percent by weight of a binder composition comprising a styrene butadiene copolymer.

The binder composition can be made using a latex adhesive commercially available as Rovene™ 5550 (49 percent solids styrene butadiene) available from Mallard Creek Polymers of Charlotte,

N.C.

One suitable airlaid non-woven substrate for use in the present invention is the airlaid nonwoven substrate employed in PAMPERS® BABY FRESH brand baby wipes marketed by The

Procter & Gamble Co. of Cincinnati, Ohio.

The art recognizes the use of dusting sheets such as those in U.S. Patent 3,629,047,

U.S. Patent 3,494 421, U.S. Patent 4,144,370, U.S. Patent 4,808,467, U.S. Patent 5,144,729, and

U.S. Patent 5,525,397, all of which are incorporated herein by reference, as effective for picking up and retaining particulate dirt. These sheets require a structure that provides reinforcement yet free fibers in order to be effective. It has been found that similar structures used dry for dusting can also be advantageously used when pre-moistened with liquid at levels of at least about 0.5 gram of chemical solution per gram of dry substrate or greater. These levels are significantly higher than the levels used for chemical additives such as mineral oils, waxes, and the like, often applied to conventional dusting sheets to enhance performance. In particular, the wipes of this invention are specifically intended to be used pre-moistened with aqueous compositions.

In one preferred embodiment, the cleaning sheet has at least two regions where the regions are distinguished by basis weight. The measure for basis weight is described in US 33 : Co Co

Provisional Applications 60/055,330 and 60/047,619. Briefly, the measurement is achieved photographically, by differentiating dark (low basis weight) and light (high basis) network regions.

In particular, the cleaning sheet comprises one or more low basis weight regions, wherein the low basis region(s) have a basis weight that is not more than about 80% of the basis weight of the high basis weight regions. In one preferred aspect, the first region is relatively high basis weight and comprises an essentially continuous network. The second region comprises a plurality of mutually discrete regions of relatively low basis weight and which are circumscribed by the high basis weight first region. In particular, a preferred cleaning sheet comprises a continuous region having a basis weight of from about 30 to about 120 grams per square meter and a plurality of discontinuous regions circumscribed by the high basis weight region, wherein the discontinuous regions are disposed in a random, repeating pattern and have a basis weight of not more than about 80% of the basis weight of the continuous region.

In one embodiment, the cleaning sheet will have, in addition to regions which differ with regard to basis weight, substantial macroscopic three-dimensionality. The term "macroscopic three-dimensionality”, when used to describe three dimensional cleaning sheets means a three dimensional pattern is readily visible to the naked eye when the perpendicular distance between the viewer's eye and the plane of the sheet is about 12 inches. In other words, the three ; dimensional structures of the pre-moistened sheets of the present invention are cleaning sheets that are non-planar, in that one or both surfaces of the sheets exist in multiple planes. By way of contrast, the term “planar”, refers to sheets having fine-scale surface aberrations on one or both sides, the surface aberrations not being readily visible to the naked eye when the perpendicular distance between the viewer's eye and the plane of the sheet is about 12 inches. In other words, on a macro scale the observer will not observe that one or both surfaces of the sheet will exist in multiple planes so as to be three-dimensional.

The measure for three-dimensionality is described in US Provisional Applications 60/055,330 and 60/047,619. Briefly, macroscopic three-dimensionality is described in terms of average height differential, which is defined as the average distance between adjacent peaks and valleys of a given surface of a sheet, as well as the average peak to peak distance, which is the average distance between adjacent peaks of a given surface. Macroscopic three dimensionality is also described in terms of surface topography index of the outward surface of a cleaning sheet; surface topography index is the ratio obtained by dividing the average height differential of a surface by the average peak to peak distance of that surface. In a preferred embodiment, a macroscopically three-dimensional cleaning sheet has a first outward surface and a second outward surface wherein at least one of the outward surfaces has a peak to peak distance of at least about 1 mm and a surface topography index from about 0.01mm to about 10 mm. The macroscopically three-dimensional structures of the pre-moistened wipes of the present invention optionally comprise a scrim, which, when heated and the cooled, contracts so as to provide further macroscopic three-dimensional structure.

In another alternative embodiment, the substrate can comprise a laminate of two outer hydroentangled substrates, such as nonwoven substrates of polyester, rayon fibers or blends thereof having a basis weight of about 10 to about 60 grams per square meter, joined to an inner constraining layer, which can be in the form of net like scrim material which contracts upon 5S heating to provide surface texture in the outer layers..

The pre-moistened wipe is made by wetting the dry substrate with at least about 1.0 gram of liquid composition per gram of dry fibrous substrate. Preferably, the dry substrate is wetted with at least about 1.5 and more preferably at least about 2.0 grams of liquid composition per ) gram of the dry fibrous substrate. The exact amount of solution impregnated on the wipe will depend on the product's intended use. For pre-moistened wipes intended to be used for cleaning counter tops, stove tops, glass, and the like, optimum wetness is from about 1 to about 5 grams of solution per gram of substrate. In the context of a floor cleaning wipe, the pre-moistened wipe can preferably include an absorbent core reservoir with a large capacity to absorb and retain fluid.

Preferably, the absorbent reservoir has a fluid capacity of from about 5 grams to about 15 grams per gram of absorptive material.. Pre-moistened wipes intended to be used for the cleaning of walls, exterior surfaces, etc. will have a capacity of from about 2 grams to about 10 grams of dry fibrous substrate.

D1. Glass Wipes: ’

Pre-moistened wipes for use on glass can comprise either mono-layer or multi-laminate substrates. In the context of mono-tayer substrates, since the surface is not wiped to dryness in ] the context of a pre-moistened wipe, it is essential that the content of non-volatile materials in the aqueous composition be kept to a minimum. Thus, the actives described above are preferably used at even lower levels for best end result. Also, it has been found that compositions consisting solely of organic hydrophobic cleaning solvents can deliver an excellent end result along with - 25 good cleaning in a pre-moistened wipe. These solvents, as opposed to the aqueous hydrophilic solvents such as ethanol, isopropanol and the like, have been found to provide better and more even surface wetting. This is important as it leads to a more uniform drying, which provides reassurance to consumers that streaks are not going to form. Additionally, while not wishing to be limited by theory, it is believed that in a soiled environment, the hydrophobic organic cleaning solvents will dry with less streaking. For example, in the context of glass wipes current mono- layer glass wipes, e.g., Glassmates™ manufactured by Reckitt & Colman, which use hydrophilic solvents only (i.e., they lack hydrophobic organic cleaning solvent) dry in spots. In the context of a pre-moistened wipe, the cleaning solvents are employed in a level of from about 0.5% to about 10%, more preferably from about 1% to about 5%. Preferred hydrophobic organic cleaning solvents include mono-propylene glyco! propyl ether, mono-propylene glycol butyl ether, mono- ethylene glycol butyl ether, and mixtures thereof. Other aqueous hydrophilic solvents such as ethanol, isopropanol, isobutano!, 2-butanal, methoxypropanol, and the like, can be used to provide perfume lift. Buffers with molecular weights of less than about 150 g/mole as described above, can be used advantageously to improve cleaning without harming end result performance.

Examples of preferred buffers include ammonia, methanol amine, ethanol amine, 2-amino-2- methyl-1-propanol, 2-dimethylamino-2-methyl-1-propanol, acetic acid, glycolic acid, and the like.

Most preferred among these are ammonia, 2-dimethylamino-2-methyl-1-propanol and acetic acid.

When used, these buffers are present from about 0.005% to about 0.5%, by weight of the composition, with the higher levels being more preferred for the more volatile chemicals. In the context of glass wipes, simple compositions using low levels of non-volatile surfactant with preferably high levels of the preferred organic cleaning solvent are sufficient to provide excellent cleaning and wetting performance even in the absence of the hydrophilic polymer. However, the addition of polymer can advantageously be used to provide other benefits such as anti-spotting, antifogging and easier next-time cleaning.

The art recognizes the use of pre-moistened wipes. For example, US Patent 4,276,338 discloses a multi-laminate absorbent article comprising adjacent first and second layers maintained together to improve wicking. US Patent 4,178,407 discloses a single towel having absorbent surface on both sides that additionally comprises an inner layer impermeable to liquid.

The towel is designed to have little wet strength and the layer of absorbent material consists of loose fibers. The art also discloses pre-moistened wipes for use in glass cleaner applications. . US Patent 4,448,704 discloses an article suitable for cleaning hard surfaces such as glass. The article may be wet or comprise compositions contained within rupturable pouches. The article of

U.S. Patent 4,448,704 is pre-washed with demineralized water or the solution used to impregnate ’ said article; the liquid composition has a surface tension of less than 35 dynes/cm, and preferably includes. a surface-active agent and a partially esterified resin such as a partially esterified styrene/maleic anhydride copolymer. All of said patents are incorporated herein by reference.

The pre-moistened wipes of the present invention advantageously are not pre-washed, yet the inventors have found that they deliver excellent end result even as single layered sheets. An additional benefit of the premoistened glass wipes is to keep linting at a minimum. Steps such as pre-washing typically loosens up fibers, making the substrate more prone to linting. In the context of hydroentangled structures specifically, the tightness of the fiber integration is optimally achieved in processing of the fibrous materials, not during the making or preparation of the pre- moistened wipe. As a result, preferred compositions of the present invention display improved linting. Additionally, the liquid composition used on the pre-moistened wipes for glass is preferably substantially free of surface active agents. As such, the surface tension of the liquid does not need to reduce surface tension below 35 dynes/cm. In the context of a multi-layered ssubstrate for the premoistened wipe of the present invention, the wipe can have two sides that differ in function. One side is pre-moistened and acts to deliver the liquid while the other is preferably not wet and is designed for buffing or finishing.

In the context of glass and other cleaning situations where lower levels of liquid are required to reduce amount of liquids left on surfaces and grease cleaning efficacy is required, a preferred embodiment includes a dry fibrous substrate substrate where at least about 65% of the dry fibrous substrate is composed of hydrophobic fibers such as polyester, polypropylene, polyethylene fibers, and the like, and lower levels of hydrophilic fibers such as wood pulp, cotton - fibers, and the like, are at levels of less than about 35%. The lower level of hydrophilic fibers ’ 5 helps reduce how much liquid the wipe can retain while the higher level of hydrophobic fibers helps to better absorb grease. Aside from benefits associated with improved grease cleaning, it has been found that hydrophobic fibers also improve the feel of the wipe on glass and other hard : surfaces, providing an easier cleaning feel to both the consumer and to the surface being treated.

E This improved ease-of-cleaning, lubricity, or “glide” can be experimentally quantified by friction . measurements on relevant hard surfaces. Improved glide from the substrate provides additional freedom in the formulation of the liquid composition.

Hydrophobic fibers in the substrate of the premoistened wipe provide glide benefits whether the wipe is completely pre-moistened and when the wipe is completely dry. This is : significant since wipes become increasingly dry as they are used. Thus, the level of C4 or higher chainlength surfactants, which are known to provide lubricity benefits, can be substantially reduced or preferably altogether eliminated from the liquid composition used in the pre-moistened wipe herein while still preserving excelient glide (low friction) characteristics. The use of wipes comprising some level of hydrophobic fibers, particularly polyester, also provides increased : flexibility in developing pre-moistened wipes for glass at acidic pH. It has been found that acidic cleaning compositions significantly hinder the glide of cellulosic substrates such as common paper towels or cellulosic pre-moistened wipes. in addition to the substrate composition, the wipe dimensions can also be used to control dosing as well as provide ergonomic appeal. Preferred wipe dimensions are from about S 1/2 inches to about 9 inches in length, and from about 5 1/2 inches to about 9 inches in width to comfortably fit in a hand. As such, the wipe preferably has dimensions such that the length and width differ by no more than about 2 inches. In the context of heavier soil cleaning, wipes are preferably bigger so that they can used and then folded, either once or twice, so as to contain dirt within the inside of the fold and then the wipe can be re-used. For this application, the wipe has a length from about 5 ¥: inches to about 13 inches and a width from about 10 inches to about 13 inches. As such, the wipe can be folded once or twice and still fit comfortably in the hand.

In addition to having wipes prepared using a mono-layer substrate, it is advantageous in some situations to have the pre-moistened wipe constructed using a multi-layer substrate. In a preferred embodiment, the wipe consists of a multi-laminate substrate comprising a pre- moistened outer layer, an impermeable film or membrane inner layer and second outer-layer which is substantially dry. To improve the wet capacity of the wipe and to protect the back layer from getting prematurely wet, an optional absorbent reservoir layer can be placed between the pre-moistened first outer-layer and the impermeable film or membrane inner tayer. Preferably,

t the dimensions of the reservoir layer are smaller than the dimensions of the two outer layers to prevent liquid wicking from the front layer onto the back layer.

The use of a multi-laminate substrate as herein described can be highly desirable in that it allows for a dry buffing step, aimed at substantially removing most of the liquid remaining on the glass following application of the wet side of the pre-moistened wipe on the glass. The inventors have found that even with a buffing step, hydrophilic polymer in the pre-moistened wipe, if present, remains on the glass providing anti-fog properties to the glass. The buffing step also provides improved overall flexibility in the level of solids used in the liquid composition because most of the solids are wiped up together with the remainder of the aqueous composition during the buffing step. In fact, those skilled in the art can recognize that it can be advantageous to use very low levels, preferably less than about 0.02%, water-soluble, though crystalline, surfactants because of improved propensity for dry the substrate to remove such crystalline solids from the glass surface.

The multi-laminate substrate is further advantageously used in the context of heavier soiled situations, such as those encountered on outside windows or car glass. By allowing use of a fresh, clean surface for buffing, the multi-laminate substrate reduces the amount of dirty liquid pushed around by the pre-moistened wipe. ; : When a multi-laminate substrate is used, it is preferred that the outer pre-moistened layer : contain at least about 30% hydrophobic fibers for oil removal and glide. The impermeable inner layer is most preferably polyethylene, polypropylene, or mixtures thereof. The composition mixture and thickness of the impermeable layer is chosen so as to minimize, or more preferably eliminate any seepage of liquid from the pre-moistened first outer-layer to the dry second outer- layer. Use of a reservoir core layer or of a high fluid capacity pre-moistened outer-layer will test the impermeable layer, such that more than one impermeable layer can be required to ensure sufficient dryness for the second outer-layer of the wipe. The reservoir layer, if present, will preferably consist of treated or untreated cellulose, either as a stand-alone material or as a hybrid with hydrophobic fibers. The hydrophobic content of the reservoir layer is preferably less than about 30%, more preferably less than about 20% by weight of the total fiber content of the layer. in a preferred embodiment, the reservoir consists of air-laid cellulose. The second outer-layer, which is substantially dry to the touch, preferably consists of high absorbency cellulose, or blends of cellulose and synthetic fibers.

The inventors have recognized that packing of the wipes that contain a pre-moistened side and a dry side can be challenging. To resolve this packing issue, a preferred folding scheme has been developed. The wipes are folded in either halves, thirds or in another suitable way such that all of the pre-moistened layers of each of the premoistened wipes are folded inward and into each other. As a result, all of the outer dry layers of successive wipes piled into a pouch, container or box, do directly contact any pre-moistened wipe sides. By “directly contact’, it is meant that all of the pre-moistened sides of the wipes are separated from dry sides by a liquid impermeable layer. By packing the wipes in such a preferred manner, it is ensured that the dry sides of the wipes do not become contaminated with liquid during storage in the wipes container and prior to use. The packing material can be made of any suitable material, including plastic or cellophane. Optionally, another means to further address potential liquid wicking into the buffing layer, is by simply adding superabsorbent polymer into the buffing layer or between the impermeable layer and the buffing layer. in a preferred embodiment, a starter kit comprises a sturdy box or other receptacle capable of holding from about eight to about twenty-four wipes which have been folded at least ‘once, and lower cost packages capable of holding from about five to about twelve wipes are used as refill packages. : importantly, the pre-moistened wipe can be used as a stand-alone or in conjunction with an implement comprising a handle and attachment device for the wipe. As used herein, implement signifies any physical means for attachment of substrate, such as pad, dry wipe pre- . moistened wipe, and the like. Optionally, but preferably, the pre-moistened wipe includes one or more preservatives so as to ensure fungistatic benefits. Examples of preservatives to be used in association with the pre-moistened wipes of the invention include methyl paraben, bronopol, } hexetidine, dichloro-s-triazinetrione, trichloro-s-triazinetrione, and quaternary ammonium salts including dioctyl dimethyl ammonium chloride, didecyl dimethyl ammonium chloride, C42, C44 and .

C4 dimethyl benzyl (Bardac® 2280 and Barquat® MB-80 sold by Lonza), and the like at concentrations below about 0.02%. Preferred preservatives include citric acid, tetrakis (hydroxymethyl phosphonium sulfate) (“THPS”), sodium pyrithione, Kathon®, and 1,2- benzisothiazolin-3-one sold by Avicia Chemicals. The preservatives, if used, are in concentrations of from about 0.001% to about 0.05%, more preferably from about 0.005% to about 0.02%, by weight of the composition. Alternatively, preservation can be achieved using product pH, by making the pH of the aqueous composition squeezed out of the pre-moistened wipe either greater than about 10.5 or less than about 3.0. Preferred pH-based preservatives include those which are highly volatile such as ammonia (for high pH) and acetic acid (for iow pH). When pH-based preservatives are used, particularly when volatile preservatives are used, the concentration of the preservative can be substantially higher than 0.02%. The use of wipes comprising hydrophobic fibers provides sufficient glide on the surface so as to even allow the use of acidic preservation agents. Additionally, a combination of preservatives can be used to achieve the desired preservation benefits. In any event, the preservative(s) can either be applied directly onto the wipe prior to the solution, or alternatively dispersed into the solution prior to moistening the wipe.

Alternatively, it can be beneficial to incorporate antimicrobial actives directly into the substrate. In this context, it is preferred to use highly water-insoluble antimicrobial actives such as those derived from heavy metals. Examples of insoluble antimicrobials include zinc pyrithione, bismuth pyrithione, copper naphthenate, copper hydroxy quinoline, and the like. Other examples

“a A of actives, which do not use heavy metals, include dichloro-s-triazinetrione and trichloro-s- triazinetrione.

D2. Premoistened Wipes for Floors, Counters, and/or Walls

The aqueous cleaning compositions described in Sections B. and C. above can be used in a pre-moistened wipe for general purpose, counter, wall and floor cleaning. The material descriptions and processes described above in Sections D. and D1. are also applicable to floor, counter and wall cleaning methods. It is particularly advantageous in the context of floor wipes to have structures with three-dimensionality. The three-dimensional structure of the substrates described above have been found to provide improved hair pick-up relative to planar sheets, which in a wet surface environment is surprising. In a preferred embodiment, the user advantageously uses slight weaving motions in an up-and-down wiping pattern to maximize hair pick-up.

Optimum wetness of the premoistened wipe is from about 1 to about 5 grams of solution per gram of wipe. In the context of a floor cleaning premoistened wipe, the substrate can optionally include an absorbent core reservoir layer with a large capacity to absorb and retain fluid.

Preferably, the absorbent reservoir layer has a fluid capacity of from about 5 to about 15 grams per gram of absorptive material. Pre-moistened wipes intended to be used for the cleaning of ‘ walls; exterior surfaces, etc. will have an absorbent capacity of from about 2 to about 10 grams of liquid per gram of dry fibrous substrate. - Since there is no rinsing step in the context of a general purpose pre-moistened wipe, it is essential that the non-volatile content be kept to a minimum to avoid film/streak residue from product. Thus, the active materials described in Section C. “General purpose and Conventional . Floor-Cleaners” above are preferably used at even iower levels for best end result. Also, it has been found that compositions consisting of primarily organic hydrophobic cleaning solvents can deliver an excellent end result along with good cleaning in the context of a general purpose pre- moistened wipe for reasons similar to those described in pre-moistened glass wipes. Buffers with molecular weights of less than about 150 g/mole can be used advantageously to improve cleaning without harming end result performance. Examples of preferred buffers include ammonia, methano! amine, ethanol amine, 2-amino-2-methyl-1-propanol, 2-dimethylamino-2- methyl-1-propanol, acetic acid, glycolic acid, and the like. Most preferred among these are ammonia, 2-dimethylamino-2-methyl-1-propanol, and acetic acid. When used, these buffers are present in from about 0.005% to about 0.5%, with the higher levels being more preferred for the more volatile chemicals. As in the case of glass wipes (see Section D1.), it has been found that simple compositions using low levels of non-volatile surfactant with preferably high levels of the preferred organic cleaning solvent are sufficient to provide excellent cleaning and wetting performance even in the absence of the hydrophilic polymer. However, the addition of polymer can advantageously be used to provide other benefits such as anti-spotting, antifogging, and easier next-time cleaning.

To provide added convenience general purpose pre-moistened wipes can be attached to a mop head with a handle. In such an execution the pre-moistened wipe is ideal for light cleaning and disinfecting. Since the amount of solution released from the wipe is much more limited than that delivered through conventional cleaning, very effective anti-microbial systems need to be used. In one such composition the general purpose and floor pre-moistened wipe can contain a solution comprising an effective level of detergent surfactant and citric acid at about 0.5 to about 5%. To boost the efficacy of such solution hydrogen peroxide or a source of hydrogen peroxide can be added at about 0.5% to about 3%. An alternative composition could use quaternary ammonium salts such as dioctyl dimethyl ammonium chloride, didecyl dimethyl ammonium chloride, Cyz, C14 and Cie dimethyl benzyl ammonium chlorides, at levels greater than about 0.05%. Such compounds have been found to often interfere with the benefits of the preferred polymers. While these solutions (e.g., those comprising sources of hydrogen peroxide, quaternary ammonium compounds and citric acid) deliver a high degree of anti-microbial efficacy they can leave a filmy surface because they are solids and need to be used at high levels.

Better end result performance is delivered by compositions containing primarily the organic cleaning solvents described above at from about 0.25% to about 10%, more preferably 0.5% to about 5% to provide cleaning and wetting, in combination with non-volatile buffers described above. Low levels of non-volatiles including hydrophilic polymer can advantageously . be incorporated such that the total level of non-volatiles excluding perfume and antimicrobials, is from about 0% to about 0.08%, more preferably from 0% to about 0.055%, most preferably from about 0% to about 0.025%. In a preferred embodiment, the combination of surfactants, wetting polymers, buffers and hydrophobic organic cleaning solvents are chosen so as a provide a surface tension reduction from water (72 dynes/cm) of more than about 25 dynes/cm, more preferably more than 30 dynes/cm, most preferably more than 35 dynes/cm. Optionally, low levels of more effective anti-microbial ingredients such as bronopol, hexitidine sold by Angus chemical (211 Sanders Road, Northbrook, lliinois, USA), Kathon®, 2-((hydroxymethyl) (amino)ethanol, propylene glycol, sodium hydroxymethyl amino acetate, formaldehyde, and glutaraldehyde, quaternary ammonium salts such as dioctyl dimethyl ammonium chloride, didecyl dimethyl ammonium chloride, C12,C14 and C16 dimethyl benzyl (Bardac® 2280 and Barquat®

MB-80 sold by Lonza), dichloro-s-triazinetrione, trichloro-s-triazinetrione, and more preferably 1,2- benzisothiazolin-3-one sold by Avicia Chemicals, chlorhexidine diacetate sold by Aldrich-Sigma, sodium pyrithione and polyhexamethylene biguanide at about 0.001% to about 0.1%, more preferably from about 0.005% to about 0.05% are added for preserving and/or providing antimicrobial benefits.

An important benefit of the wet wipes of the present invention is the fact that judicious selection of the antimicrobial actives combined with the lack of a rinsing step as preferred in the present invention, and lack of a buffing step (consumers are in the habit of cleaning floors and countertops to a wet end result), allow for residual disinfectancy benefits. By residual fi) disinfectancy, it is meant that the residual antimicrobial actives delivered by the wet wipe onto the hard surface at least about 99.9% cidal against bacteria and other microorganisms for a period of from about 8 to about 72 hours, more preferably from about 12 to about 48 hours, most preferably at least about 24 hours. While residual disinfectancy can be achieved using conventional approaches (i.e., spray product with a paper towel, sponge, rag, etc.), the premoistened wipe has the added convenience of delivering the cleaning and disinfectancy benefits in one package. The residual properties result from a combination of low vapor pressure and high cidal efficacy of the antimicrobial actives associated with the compositions of the present invention. Those skilled in the art will recognize that residual disinfectancy benefits, if present in the context of compositions comprising a very low level of surfactant, are even more easily achieved in compositions wherein the level of surfactants is raised. Residual disinfectancy, in addition to excellent end result, can provide consumers with reassurance as to the effectiveness of the wet wipe. Such reassurance is most important for tasks such as cleaning of surfaces that are particularly susceptible to harboring germs, most particularly counter tops, stove tops, appliances, sinks, furniture, showers, glass and other fixtures that are near or inside the kitchen or bathroom(s).

Preferred antimicrobial actives for residual benefits as delivered from a wet wipe or a dry wipe that becomes wet as a result of contact with a wet composition during the cleaning process, : include ‘Kathon®, 2-({hydroxymethyl) (amino)ethano!, propylene glycol, sodium hydroxymethyl amino acetate, formaldehyde, and glutaraldehyde, quaternary ammonium salts such as diocty! dimethyl ammonium chloride, octyl decyl dimethyl ammonium chloride, didecyl dimethyl ammonium chloride, Cy,,Cq4 and C,¢ dimethyl benzyl (Bardac® 2280 and Barquat® MB-80 sold by Lonza), dichioro-s-triazinetrione, trichloro-s-triazinetrione, and more preferably tetrakis(hydroxymethyl) phosphonium sulphate (THPS), 1,2-benziscthiazolin-3-one sold by Avicia

Chemicals, chlorhexidine diacetate sold by Aldrich-Sigma, sodium pyrithione and polyhexamethylene biguanide at about 0.001% to about 0.1%, more preferably from about 0.005% to about 0.05%. The specific antimirobial actives and combinations thereof are chosen so as to be effective against specific bacteria, as desired by the formulator. Preferably, the antimicrobial actives are chosen to be effective against gram-positive and gram-negative bacteria, enveloped and non-enveloped viruses, and molds that are commonly present in consumer homes, hotels, restaurants, commercial establishments and hospitals. Most preferably, the antimicrobials provide residual disinfectancy against Salmanella choleraesuis, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli, and combinations thereof. Wherever possible, the antimicrobial actives are chosen to have residual disinfectancy benefits against more than one bacterial organism, and more preferably against at least one gram-negative organism and at least one gram-positive organism.

The inventors have found that residual disinfectancy can also be achieved or enhanced using pH. Additionally, use of low levels of surfactants to reduce surface tension by more than about 25 dynes/cm, preferably more than about 30 dynes/cm, can advantageously be used in combination with pH effects in the context of a pre-moistened wipe. Thus, compositions at a pH 10.5 or greater or a pH of 3 or lower are found to deliver the desired residual efficacy. The preferred hydrophilic, substantive polymer can be used to improve residuality, particularly for voltaile actives such as acetic acid. The use of pH can also help lower the level of the above actives needed to achieve residual. Preferred actives that are effective as a result of pH include lactic acid, glycolic acid, Cs,Cs,Cy fatty acids, sodium hydroxide, potassium hydroxide.

This approach, i.e., using a combination of hydrophobic organic solvent plus volatile buffer plus optionally low levels of non-volatile raw materials to deliver a superior end result, in combination with effective and low streaking antimicrobials, can be used in a variety of practical applications herein disclosed, including general purpose cleaners, glass cleaners, glass cleaner wipes, solutions used with disposable pads (either with or without mop implements).

Use of low levels of non-volatiles in the compositions of the invention presents a challenge for perfume incorporation. Some methods to improve solubility of perfume are disclosed below. However, in certain instances, particularly when hydrophobic perfumes are desired, perfume incorporation can be problematic. To circumvent this issue, the inventors have advantageously found that perfume delivery can be achieved by directly applying concentrated perfume to either the wipe (or pad). In this manner, virtually any perfume can be used. In order to minimize any residue negatives that can be caused by the concentrated perfume, the perfume is preferentially applied to the perimeter of the wipe or pad, or to areas that do not directly contact the surface to be treated. In another embodiment, perfume can also be added into the package containing the wipes. In similar fashion, use of low levels of non-volatile actives makes incorporation of effective suds suppressors into the aqueous composition more difficult. It has been found that suds suppressors can more easily, and more effectively be applied directly to the wipe to prevent suds control. it is found that this not only addresses a consumer perception of too : 25 much sudsing, but surprisingly also has shown an improved end result upon surface drying.

Furthermore, it has been found that applying suds suppressor directly onto the wipes makes process a lot easier through better control of suds during manufacturing and packaging.

Preferred suds suppressors are those that are effective at levels of no more than about 0.1 grams of suds suppressor per gram of substrate, more preferably at levels less than about 0.01 grams suds suppressor per gram of substrate, most preferably, less than about 0.005 grams suds suppressor per gram of substrate. The most preferred suds suppressor in this context is DC AF, manufactured by the Dow Corning company. The use of suds suppressors to improve surface appearance is particularly significant since these materials are effective at very low levels.

E. Floor Cleaning Compositions for Use with Disposable Cleaning Pads

The compositions described in the previous sections on glass wipes and floor wipes also pertain to a cleaning system where solution is applied to the surface and then cleaned with a disposable cleaning pad particularly since it again involves a no-rinse cleaning application. The proper selection of ingredients and levels used can have a significant impact on performance.

. 5 e. optionally, an effective amount, up to 1%, preferably from about 0.01 % to about 0.5%, more preferably from about 0.025% to about 0.25%, of either an unsubstituted or substituted cyclodextrin, either alpha, beta, or gamma cyclodextrin substituted, optionally, with short chain (1-4 carbon atoms) alkyl or hydroxyalkyl groups, preferably beta-cyclodextrin, hydroxypropyl! cyclodextrin or mixtures thereof;

j. optionally, detergent builder; and optionally, but preferably, the balance being an aqueous solvent system, comprising water, and optional water soluble solvent, and wherein said composition has a pH under usage conditions of from about 2 to about 12, preferably from about 3 to about 11.5, the level of hydrophobic materials, including hydrophobic cleaning solvents being limited.

These detergent compositions are used in combination with a disposable, preferably superabsorbent, cleaning pad, preferably attached to an implement which facilitates its use.

Preferred detergent compositions which can be used with the preferred pads containing superabsorbent material and optional implement, described hereinafter, require sufficient detergent to enable the solution to provide cleaning without overloading the superabsorbent material with solution, but, typically, if there is more than about 0.5% detergent surfactant the performance suffers.

Therefore, the level of detergent surfactant is preferably from about 0.001%to about 0.5%, more preferably from about 0.005% to about 0.4%, and even more preferably from about 0.02% to about 0.3%, by weight of the composition.

The level of hydrophobic materials, including cleaning solvent, is preferably less than about 7%, more preferably less than about 6%, and even more preferably less than about

5% and the pH is typically provided, at least in part, by volatile materials, to minimize streaking/filming problems.

In some cases an alkaline pH is preferred where soils are higher in

Lo grease composition while in other cases a lower pH is preferred where soils could have calcium or calcium soap deposits.

Preferred buffers include ammonia, methanol amine, ethanol amine, 2-amino-2-methyl-1- propanol, 2-dimethylamino-2-methyl-1-propanol, acetic acid, glycolic acid and the like. Most preferred among these are ammonia, 2-dimethylamino-2-methyl-1-propanol and acetic acid.

Suitable hydrophobic cleaning solvents include short chain (e.g., C1-Cg) derivatives of oxyethylene glycol and oxypropylene glycol, such as mono- and di-ethylene glycol n-hexyl ether, mono-, di- and tri-propylene glycol n-butyl ether, and the like, most preferably propoxypropanol.

The level of hydrophobic cleaning solvent, e.g., solvent having a solubility in water of less than about 10%, is in the cleaning composition at less than about 6%, more preferably less than about 5% by weight of the composition.

Suitable detergent builders include those derived from phosphorous sources, such as orthophosphates, pyrophosphates, tripolyphosphates, etc., and those derived from non- phosphorous sources, such as nitrilotriacetates; S,S-ethylene diamine disuccinates; and the like.

Suitable chelants include ethylenediaminetetraacetates; citrates; and the like. Suitable suds suppressors include silicone polymers and linear or branched C4g-Cqg fatty acids or alcohols. } Suitable detergent enzymes include lipases, proteases, amylases and other enzymes known to be useful for catalysis of soil degradation. The total level of such ingredients is low, preferably less than about 0.1%, more preferably less than about 0.05%, to avoid causing filming/streaking . 20 problems. Preferably, the compositions should be essentially free of materials that cause filming/streaking problems. Accordingly, it is desirable to use alkaline materials that do not cause filming and/or streaking for the majority of the buffering. Suitable alkaline buffers are carbonates, bicarbonates, citrates, etc. The preferred alkaline buffers are alkanol amines having the formula:

CR2(NR2)CR,0OH wherein each R is selected from the group consisting of hydrogen and alkyl groups containing from one to four carbon atoms and the total of carbon atoms in the compound is from three to six, preferably, 2-dimethylamino-2-methyl-1-propanol.

Soil suspending agents, preferably water soluble polymers, for use in the detergent composition and/or cleaning solution of this invention in addition to the said hydrophilic polymers, can optionally be selected from a group consisting of, ethoxylated and/or propoxylated polyalkylamines, carboxylate polymers, nitrogen-based zwitterionic polymers, polyethyleneoxides, polyphosphates, and cellulosic polymers. Preferred soil suspending agents are ethoxylated polyalkylamines. Such agents are disclosed in U. S. Pat. Patent Number: 4,891,160, issued

Eugene P.; and Zhang, Shulin, incorporated herein by reference.

An improvement in soil suspension can be achieved at all mixing ratios of the vinyl pyrrolidone polymer and the nonionic cellulose ether. Preferably, the ratio of the vinyl pyrrolidone polymer to the nonionic cellulose ether in the detergent composition is within the range from about 8:2 to about 2:8, most preferably from about 6:4 to about 4:6, by weight. Mixtures of this type are disclosed in U. S. Pat. Patent Number: 4,999,129, entitled Process and composition for washing soiled polyester fabrics, by Michael Hull.

In one preferred embodiment, similar to learnings on glass and floor wipes, using high levels of an organic cleaning solvent while minimizing the level of non-volatile ingredients can be advantageous, resulting in good cleaning without leaving haze or streaks particularly on tough to clean surfaces like ceramic. These compositions contain primarily the organic cleaning solvents from about 0.5% to about 10%, more preferably 1% to about 5% to provide cleaning and wetting, in combination with non-volatile buffers described above. Low levels of non-volatiles including . hydrophilic polymer can advantageously be incorporated such that the total level of non-volatiles excluding perfume and antimicrobials, is from about 0% to about 0.2%, more preferably from 0% to about 0.1%, more preferably from about 0% to about 0.055% and most preferably from about 0% to about 0.025%. Also as in the case of glass wipes and floor, counter and wall wipes, the inventors have found that simple compositions using low levels of non-volatile surfactant with preferably high levels of the preferred organic cleaning solvent are sufficient to provide excellent cleaning and wetting performance even in the absence of the hydrophilic polymer. However, the addition of polymer can advantageously be used to provide other benefits such as anti-spotting, antifogging and easier next-time-cleaning. In a preferred embodiment, the combination of surfactants, wetting polymers, buffers and hydrophobic organic cleaning solvents are chosen so as a provide a surface tension reduction from water (72 dynes/cm) of more than about 25 dynesicm, more preferably more than 30 dynes/cm, most preferably more than 35 dynes/cm.

Optionally, low levels anti-microbial ingredients such as bronopol, hexitidine sold by

Angus chemical (211 Sanders Road, Northbrook, illinois, USA), dichloro-s-triazinetrione, trichloro- s-triazinetrione, quaternary ammonium salts including dioctyl dimethyl ammonium chloride, octyl decyl ammmonium chloride, didecyl dimethyl ammonium chloride, C12,C14 and C16 dimethyl benzyl (Bardac® 2280 and Barquat® MB-80 sold by Lonza), Kathon®, 2-((hydroxymethyl) (amino)ethanol, propylene glycol, sodium hydroxymethyl amino acetate, formaldehyde, and glutaraldehyde, and more preferably tetrakis (hydroxymethyl phosphonium sulfate (THPS), 1,2- benzisothiazolin-3-one, chlorhexidine diacetate, sodium pyrithione and polyhexamethylene biguanide at about 0.001% to about 0.1%, more preferably from about 0.005% to about 0.05% can be added for preserving and/or providing antimicrobial benefits while maintaining good end result.As in the case of the wet wipe (part D, D1 and D2.), residual disinfectancy benefits can be important for consumers cleaning counter tops, stove tops, appliances, sinks, furniture, and other fixtures that are near or inside the kitchen or bathroom(s), and to a lesser extent in the cleaning of floors, glass and walls. Such benefits can be delivered via one or more of these antimicrobial actives. A full discussion of residual disinfectancy is provided in section D, D1 and D2 (“Wet- wipe” for Floors and/or Counters and Walls).

The cleaning pads will preferably have an absorbent capacity, when measured under a confining pressure of 0.09 psi after 20 minutes (1200 seconds) (hereafter referred to as "t1200 absorbent capacity"), of at least about 10 g deionized water per g of the cleaning pad. The absorbent capacity of the pad is measured at 20 minutes (1200 seconds) after exposure to deionized water, as this represents a typical time for the consumer to clean a hard surface such as a floor. The confining pressure represents typical pressures exerted on the pad during the cleaning process. As such, the cleaning pad should be capable of absorbing significant amounts of the cleaning solution within this 1200 second period under 0.09 psi. The cleaning pad will preferably have a t120p absorbent capacity of at least about 15 g/g, more preferably at least ) about 20 g/g, still more preferably at least about 25 g/g and most preferably at least about 30 g/g.

The cleaning pad will preferably have a tggg absorbent capacity of at least about 10 g/g, more ’ 20 preferably a tggq absorbent capacity of at least about 20 g/g.

Values for t1200 and tggg absorbent capacity are measured by the performance under pressure (referred to herein as "PUP") method, which is described in detail in the Test Methods section in allowed application Serial Number 08/756,507, Holt, Masters, and Ping, filed November 26, 1996, said application being incorporated herein, in its entirety, by reference. The application contains a more complete disclosure of the pads, instruments, etc. that are of use herein.

The cleaning pads will also preferably, but not necessarily, have a total fluid capacity (of deionized water) of at least about 100 g, more preferably at least about 200 g, still more preferably at least about 300 g and most preferably at least about 400 g. While pads having a total fluid capacity less than 100 g are within the scope of the invention, they are not as well suited for cleaning large areas, such as seen in a typical household, as are higher capacity pads.

Pads that absorb less than about 100 g or less can be advantageous, particularly when : used with in conjunction preferred liquid compositions described above for cleaning and disinfecting smaller areas like bathroom floors or for consumers who typically have smaller areas of washable floors in their home of about 100 square feet or less. Under these situations consumers will be less forced to keep partially used pads which still have absorptive capacity available. These pads can also be advantageous in that maybe better suited for spill pick-up where again keeping partially used pads is not desired. This pad can be composed of an absorbent structure with or without superabsorbent polymer.

In the pads there is preferably an absorbent layer which serves to retain any fluid and soil absorbed by the cleaning pad during use and a scrubbing layer. While the preferred scrubbing ayer, described hereinafter, has some effect on the pad's ability to absorb fluid, the preferred absorbent layer plays a major role in achieving the desired overall absorbency. Furthermore, the absorbent layer preferably comprises multiple layers which are designed to provide the cleaning pad with multiple planar surfaces.

From the essential fluid absorbency perspective, the absorbent layer is preferably capable of removing fluid and soil from any "scrubbing layer" so that the scrubbing layer will have capacity to continually remove soil from the surface. The absorbent layer also is preferably capable of retaining absorbed material under typical in-use pressures to avoid "squeeze-out” of absorbed soil, cleaning solution, etc.

The absorbent layer can comprise any material that is capable of absorbing and retaining fluid during use. To achieve desired total fluid capacities, it will be preferred to include in the absorbent layer a material having a relatively high fluid capacity (in terms of grams of fluid per gram of absorbent material). As used herein, the term "superabsorbent material” means any absorbent material having a g/g capacity for water of at least about 15 g/g, when measured under . a confining pressure of 0.3 psi. Because a majority of the cleaning fluids useful with the present invention are aqueous based, it is preferred that the superabsorbent materials have a relatively high g/g capacity for water or water-based fluids.

Representative superabsorbent materials include water insoluble, water-swellable superabsorbent gelling polymers (referred to herein as "superabsorbent gelling polymers”) which are well known in the literature. These materials demonstrate very high absorbent capacities for water. The superabsorbent gelling polymers useful in the present invention can have a size, shape and/or morphology varying over a wide range. These polymers can be in the form of particles that do not have a large ratio of greatest dimension to smallest dimension (e.g., granules, flakes, pulverulents, interparticle aggregates, interparticle crosslinked aggregates, and the like) or they can be in the form of fibers, sheets, films, foams, laminates, and the like. The use of superabsorbent gelling polymers in fibrous form provides the benefit of providing enhanced retention of the superabsorbent material, relative to particles, during the cleaning process. While their capacity is generally lower for aqueous-based mixtures, these materials still demonstrate significant absorbent capacity for such mixtures. The patent literature is replete with disclosures of water-swellable materials. See, for example, U.S. Patent 3,699,103 (Harper et al.), issued

June 13, 1972; U.S. Patent 3,770,731 (Harmon), issued June 20, 1972; U.S. Reissue Patent 32,649 (Brandt et al.), reissued April 19, 1989; U.S. Patent 4,834,735 (Alemany et al.), issued

May 30, 1989.

Superabsorbent gelling polymers useful in the present invention include a variety of water- insoluble, but water-swellable polymers capable of absorbing large quantities of fluids. Such polymeric materials are also commonly referred to as “hydrocolloids”, and can include polysaccharides such as carboxymethyl starch, carboxymethyl cellulose, and hydroxypropyl cellulose; nonionic types such as polyvinyl alcohol, and polyvinyl ethers; cationic types such as polyviny! pyridine, polyvinyl morpholine, and N N-dimethylaminoethyl or N,N-diethylaminopropyl acrylates and methacrylates, and the respective quaternary salts thereof. Well-known materials and are described in greater detail, for example, in U.S. Patent 4,076,663 (Masuda et al), issued

February 28, 1978, and in U.S. Patent 4,062,817 (Westerman), issued December 13, 1977, both of which are incorporated by reference.

Preferred superabsorbent gelling polymers contain carboxy groups. These polymers include hydrolyzed starch-acrylonitrile graft copolymers, partially neutralized hydrolyzed starch- acrylonitrile graft copolymers, starch-acrylic acid graft copolymers, partially neutralized starch- acrylic acid graft copolymers, saponified vinyl acetate-acrylic ester copolymers, hydrolyzed acrylonitrile or acrylamide copolymers, slightly network crosslinked polymers of any of the foregoing copolymers, partially neutralized polyacrylic acid, and slightly network crosslinked polymers of partially neutralized polyacrylic acid. These polymers can be used either solely or in “ the form of a mixture of two or more different polymers. Examples of these polymer materials are disclosed in U.S. Patent 3,661,875, U.S. Patent 4,076,663, U.S. Patent 4,093,776, U.S. Patent 4,666,983, and U.S. Patent 4,734,478, all of said patents being incorporated by reference. : Most preferred polymer materials for use in making the superabsorbent gelling polymers i are slightly network crosslinked polymers of partially neutralized polyacrylic acids and starch : derivatives thereof. Most preferably, the hydrogel-forming absorbent polymers comprise from about 50 to about 95%, preferably about 75%, neutralized, slightly network crosslinked, polyacrylic acid (i.e. poly (sodium acrylate/acrylic acid)). Network crosslinking renders the polymer substantially water-insoluble and, in part, determines the absorptive capacity and extractable polymer content characteristics of the superabsorbent gelling polymers. Processes for network crosslinking these polymers and typical network crosslinking agents are described in greater detail in U.S. Patent 4,076,663.

While the superabsorbent gelling polymers is preferably of one type (i.e., homogeneous), mixtures of polymers can also be used in the implements of the present invention. For example, mixtures of starch-acrylic acid graft copolymers and slightly network crosslinked polymers of partially neutralized polyacrylic acid can be used in the present invention.

While any of the superabsorbent gelling polymers described in the prior art can be useful in the present invention, where significant levels (e.g., more than about 50% by weight of the absorbent structure) of superabsorbent gelling polymers are to be included in an absorbent structure, and in particular where one or more regions of the absorbent layer will comprise more than about 50%, by weight of the region, the problem of gel blocking by the swollen particles can impede fluid flow and thereby adversely affect the ability of the gelling polymers to absorb to their full capacity in the desired period of time. U.S. Patent 5,147,343 (Kellenberger et al.), issued

September 15, 1992 and U.S. Patent 5,149,335 (Kellenberger et al.), issued September 22, 1992, describe superabsorbent gelling polymers in terms of their Absorbency Under Load (AUL), where gelling polymers absorb fluid (0.9% saline) under a confining pressure of 0.3 psi. (The disclosure of each of these patents is incorporated herein by reference.) The methods for determining AUL are described in these patents. Polymers described therein can be particularly useful in embodiments of the present invention that contain regions of relatively high levels of superabsorbent gelling polymers. In particular, where high concentrations of superabsorbent gelling polymer are incorporated in the cleaning pad, those polymers will preferably have an AUL, measured according to the methods described in U.S. Patent 5,147,343, of at least about 24 ml/g, more preferably at least about 27 ml/g after 1 hour; or an AUL, measured according to the “methods described in U.S. Patent 5,149,335, of at least about 15 ml/g, more preferably at least ‘about 18 ml/g after 15 minutes. Commonly assigned U.S. application Serial Numbers 08/219,547 (Goldman et al.), filed March 29, 1994 and 08/416,396 (Goldman et al.), filed April 6, 1995 (both of which are incorporated by reference herein}, also address the problem of gel blocking and describe superabsorbent gelling polymers useful in overcoming this phenomena. These applications specifically describe superabsorbent gelling polymers which avoid gel blocking at . even higher confining pressures, specifically 0.7 psi. In the embodiments of the present invention where the absorbent layer will contain regions comprising high levels (e.g., more than about 50% by weight of the region) of superabsorbent gelling polymer, it can be preferred that the superabsorbent gelling polymer be as described in the aforementioned applications by Goldman et al.

Other useful superabsorbent materials include hydrophilic polymeric foams, such as : 25 those described in commonly assigned U.S. patent application Serial No. 08/563,866 (DesMarais et al.), filed November 29, 1995 and U.S. Patent No. 5,387,207 (Dyer et al.), issued February 7, 1995. These references describe polymeric, hydrophilic absorbent foams that are obtained by polymerizing a high internal phase water-in-oil emulsion (commonly referred to as HIPEs). These foams are readily tailored to provide varying physical properties (pore size, capillary suction, density, etc.) that affect fluid handling ability. As such, these materials are particularly useful, either alone or in combination with other such foams or with fibrous structures, in providing the overall capacity required by the present invention.

Where superabsorbent material is included in the absorbent layer, the absorbent layer will preferably comprise at least about 15%, by weight of the absorbent layer, more preferably at least about 20%, still more preferably at least about 25%, of the superabsorbent material.

The absorbent layer can also consist of or comprise fibrous material. Fibers useful in the present invention include those that are naturally occurring (modified or unmodified), as well as synthetically made fibers. Examples of suitable unmodified/modified naturally occurring fibers
