DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a cleaning wipe for dishware, flatware, pots and pans which comprises approximately:

(a) 20 wt. % to 95 wt. % of a water insoluble substrate; and

(b) 5 wt. % to 80 wt. % of a liquid cleaning composition being coated onto and/or impregnated into said water insoluble substrate, wherein said liquid cleaning composition comprises:

(i) 5 wt. % to 50 wt. %, more preferably 8 wt. % to 40 wt. % of at least one anionic surfactant selected from the group of sulfate anionic surfactants and sulfonated anionic surfactants and mixtures thereof; and

(ii) the balance being water, wherein the composition has a pH of 3 to 7 and does not contain ammonium hydroxide, an alkali metal hydroxide, potassium sorbate, a polysaccharide polymer, a polycarboxylate polymer, polyvinyl alcohol polymer, polyvinylpyrrolidone polymer, methyl vinyl ether polymer and the cleaning composition has a Gram Positive Residual Effective Index as measured by the method set forth in U.S. Pat. No. 6,284,259 of less than 0.35, preferably less than 0.3.

Suitable water-soluble non-soap, anionic surfactants used in the instant compositions include those surface-active or detergent compounds which contain an organic hydrophobic group containing generally 8 to 26 carbon atoms and preferably 10 to 18 carbon atoms in their molecular structure and at least one water-solubilizing group selected from the group of sulfonate, sulfate and carboxylate so as to form a water-soluble detergent. Usually, the hydrophobic group will include or comprise a C 8 -C 22 alkyl, alkyl or acyl group. Such surfactants are employed in the form of water-soluble salts and the salt-forming cation usually is selected from the group consisting of sodium, potassium, ammonium, magnesium and mono-, di- or tri-C 2 -C 3 alkanolammonium, with the sodium, magnesium and ammonium cations again being preferred.

Examples of suitable sulfonated anionic surfactants are the well known higher alkyl mononuclear aromatic sulfonates such as the higher alkyl benzene sulfonates containing from 10 to 16 carbon atoms in the higher alkyl group in a straight or branched chain, C 8 -C 15 alkyl toluene sulfonates and C 8 -C 15 alkyl phenol sulfonates.

A preferred sulfonate is a mixture of an alkali metal ammonium salt and an alkaline earth metal salt of a linear alkyl benzene sulfonate having a high content of 3- (or higher) phenyl isomers and a correspondingly low content (well below 50%) of 2- (or lower) phenyl isomers, that is, wherein the benzene ring is preferably attached in large part at the 3 or higher (for example, 4, 5, 6 or 7) position of the alkyl group and the content of the isomers in which the benzene ring is attached in the 2 or 1 position is correspondingly low.

Other suitable anionic surfactants are the olefin sulfonates, including long-chain alkene sulfonates, long-chain hydroxyalkane sulfonates or mixtures of alkene sulfonates and hydroxyalkane sulfonates. These olefin sulfonate detergents may be prepared in a known manner by the reaction of sulfur trioxide (SO 3 ) with long-chain olefins containing 8 to 25, preferably 12 to 21 carbon atoms and having the formula RCH═CHR 1 where R is a higher alkyl group of 6 to 23 carbons and R 1 is an alkyl group of 1 to 17 carbons or hydrogen to form a mixture of sultones and alkene sulfonic acids which is then treated to convert the sultones to sulfonates. Preferred olefin sulfonates contain from 14 to 16 carbon atoms in the R alkyl group and are obtained by sulfonating an α-olefin.

Other examples of suitable anionic sulfonate surfactants are the paraffin sulfonates containing 10 to 20, preferably 13 to 17, carbon atoms. Primary paraffin sulfonates are made by reacting long-chain alpha olefins and bisulfites and paraffin sulfonates having the sulfonate group distributed along the paraffin chain are shown in U.S. Pat. Nos. 2,503,280; 2,507,088; 3,260,744; 3,372,188; and German Patent 735,096.

Examples of satisfactory anionic sulfate surfactants are the alkali metal or ammonium salt C 8 -C 18 alkyl sulfate salts the ethoxylated C 8 -C 18 alkyl ether sulfate salts having the formula R(OC 2 H 4 ) n OSO 3 M wherein n is 1 to 12, preferably 1 to 5, and M is a metal cation selected from the group consisting of sodium, potassium, ammonium, magnesium and mono-, di- and triethanol ammonium ions. The alkyl sulfates may be obtained by sulfating the alcohols obtained by reducing glycerides of coconut oil or tallow or mixtures thereof and neutralizing the resultant product.

On the other hand, the ethoxylated alkyl ether sulfates are obtained by sulfating the condensation product of ethylene oxide with a C 8 -C 18 alkanol and neutralizing the resultant product. The alkyl sulfates may be obtained by sulfating the alcohols obtained by reducing glycerides of coconut oil or tallow or mixtures thereof and neutralizing the resultant product. The ethoxylated alkyl ether sulfates differ from one another in the number of moles of ethylene oxide reacted with one mole of alkanol. Preferred alkyl sulfates and preferred ethoxylated alkyl ether sulfates contain 10 to 16 carbon atoms in the alkyl group.

The ethoxylated C 8 -C 12 alkylphenyl ether sulfates containing from 2 to 6 moles of ethylene oxide in the molecule also are suitable for use in the inventive compositions. These surfactants can be prepared by reacting an alkyl phenol with 2 to 6 moles of ethylene oxide and sulfating and neutralizing the resultant ethoxylated alkylphenol.

Other suitable anionic surfactants are the C 9 -C 15 alkyl ether polyethenoxyl carboxylates having the structural formula R(OC 2 H 4 ) n OX COOH wherein n is a number from 4 to 12, preferably 5 to 10 and X is selected from the group consisting of

wherein R 1 is a C 1 -C 3 alkylene group. Preferred compounds include C 9 -C 11 alkyl ether polyethenoxy (7-9) C(O) CH 2 CH 2 COOH, C 13 -C 15 alkyl ether polyethenoxy (7-9)

and C 10 -C 12 alkyl ether polyethenoxy (5-7) CH2COOH. These compounds may be prepared by condensing ethylene oxide with appropriate alkanol and reacting this reaction product with chloracetic acid to make the ether carboxylic acids as shown in U.S. Pat. No. 3,741,911 or with succinic anhydride or phthalic anhydride. Obviously, these anionic. surfactants will be present either in acid form or salt form depending upon the pH of the final composition, with salt forming cation being the same as for the other anionic surfactants.

The instant composition can also contain a surfactant selected from the group consisting of amine oxides, alkyl polyglucosides, zwitterionics and C 12-14 fatty acid alkanolamides and mixtures thereof.

The instant composition can optionally include 0.1 wt. % to 15 wt. % of a water-soluble zwitterionic surfactant, which can also be used provides good foaming properties and mildness to the present nonionic based liquid detergent. The zwitterionic surfactant is a water soluble betaine having the general formula:

wherein R 1 is an alkyl group having 10 to 20 carbon atoms, preferably 12 to 16 carbon atoms, or the amido radical:

wherein R is an alkyl group having 9 to 19 carbon atoms and a is the integer 1 to 4; R 2 and R 3 are each alkyl groups having 1 to 3 carbons and preferably 1 carbon; R 4 is an alkylene or hydroxyalkylene group having from 1 to 4 carbon atoms and, optionally, one hydroxyl group. Typical alkyldimethyl betaines include decyl dimethyl betaine or 2-(N-decyl-N,N-dimethyl-ammonia) acetate, coco dimethyl betaine or 2-(N-coco N,N-dimethylammonio) acetate, myristyl dimethyl betaine, palmityl dimethyl betaine, lauryl diemethyl betaine, cetyl dimethyl betaine, stearyl dimethyl betaine, etc. The amidobetaines similarly include cocoamidoethylbetaine, cocoamidopropyl betaine and the like. A preferred betaine is coco (C 8 -C 18 ) amidopropyl dimethyl betaine.

The instant composition can optionally include 0.1 wt. % to 15 wt. % of an amine oxide semi-polar nonionic surfactants comprise compounds and mixtures of compounds having the formula:

wherein R 1 is an alkyl, 2-hydroxyalkyl, 3-hydroxyalkyl, or 3-alkoxy-2-hydroxypropyl radical in which the alkyl and alkoxy, respectively, contain from 8 to 18 carbon atoms, R 2 and R 3 are each methyl, ethyl, propyl, isopropyl, 2-hydroxyethyl, 2-hydroxypropyl, or 3-hydroxypropyl, and n is from 0 to 10. Particularly preferred are amine oxides of the formula:

wherein R 1 is a C 12-16 alkyl and R 2 and R 3 are methyl or ethyl. The above ethylene oxide condensates, amides, and amine oxides are more fully described in U.S. Pat. No. 4,316,824 which is hereby incorporated herein by reference.

The instant composition can optionally contain 0.1 wt. % to 10 wt. % of a C 12-14 alkyl monoalkanol amide such as lauryl monoalkanol amide or a C 12-14 alkyl dialkanol amide such as lauryl diethanol amide or coco diethanol amide.

The alkyl polysaccharides surfactants, which can be optionally used at a concentration of 0.1 wt. % to 15 wt. % have a hydrophobic group containing from about 8 to about 20 carbon atoms, preferably from about 10 to about 16 carbon atoms, most preferably from about 12 to about 14 carbon atoms, and polysaccharide hydrophilic group containing from about 1.5 to about 10, preferably from about 1.5 to about 4, most preferably from about 1.6 to about 2.7 saccharide units (e.g., galactoside, glucoside, fructoside, glucosyl, fructosyl; and/or galactosyl units). Mixtures of saccharide moieties may be used in the alkyl polysaccharide surfactants. The number x indicates the number of saccharide units in a particular alkyl polysaccharide surfactant. For a particular alkyl polysaccharide molecule x can only assume integral values. In any physical sample of alkyl polysaccharide surfactants there will be in general molecules having different x values. The physical sample can be characterized by the average value of x and this average value can assume non-integral values. In this specification the values of x are to be understood to be average values. The hydrophobic group (R) can be attached at the 2-, 3-, or 4-positions rather than at the 1-position, (thus giving e.g. a glucosyl or galactosyl as opposed to a glucoside or galactoside). However, attachment through the 1-position, i.e., glucosides, galactoside, fructosides, etc., is preferred. In the preferred product the additional saccharide units are predominately attached to the previous saccharide unit's 2-position. Attachment through the 3-, 4-, and 6-positions can also occur. Optionally and less desirably there can be a polyalkoxide chain joining the hydrophobic moiety (R) and the polysaccharide chain. The preferred alkoxide moiety is ethoxide.

Typical hydrophobic groups include alkyl groups, either saturated or unsaturated, branched or unbranched containing from about 8 to about 20, preferably from about 10 to about 18 carbon atoms. Preferably, the alkyl group is a straight chain saturated alkyl group. The alkyl group can contain up to 3 hydroxy groups and/or the polyalkoxide chain can contain up to about 30, preferably less than about 10, alkoxide moieties.

Suitable alkyl polysaccharides are decyl, dodecyl, tetradecyl, pentadecyl, hexadecyl, and octadecyl, di-, tri-, tetra-, penta-, and hexaglucosides, galactosides, lactosides, fructosides, fructosyls, lactosyls, glucosyls and/or galactosyls and mixtures thereof.

The alkyl monosaccharides are relatively less soluble in water than the higher alkyl polysaccharides. When used in admixture with alkyl polysaccharides, the alkyl monosaccharides are solubilized to some extent. The use of alkyl monosaccharides in admixture with alkyl polysaccharides is a preferred mode of carrying out the invention. Suitable mixtures include coconut alkyl, di-, tri-, tetra-, and pentaglucosides and tallow alkyl tetra-, penta-, and hexaglucosides.

The preferred alkyl polysaccharides are alkyl polyglucosides having the formula

R 2 O(C n H 2n O)r(Z) x

wherein Z is derived from glucose, R is a hydrophobic group selected from the group consisting of alkyl, alkylphenyl, hydroxyalkylphenyl, and mixtures thereof in which said alkyl groups contain from about 10 to about 18, preferably from about 12 to about 14 carbon atoms; n is 2 or 3 preferably 2, r is from 0 to 10, preferable 0; and x is from 1.5 to 8, preferably from 1.5 to 4, most preferably from 1.6 to 2.7. To prepare these compounds a long chain alcohol (R 2 OH) can be reacted with glucose, in the presence of an acid catalyst to form the desired glucoside. Alternatively the alkyl polyglucosides can be prepared by a two step procedure in which a short chain alcohol (R 1 OH) can be reacted with glucose, in the presence of an acid catalyst to form the desired glucoside. Alternatively the alkyl polyglucosides can be prepared by a two step procedure in which a short chain alcohol (C 1-6 ) is reacted with glucose or a polyglucoside (x=2 to 4) to yield a short chain alkyl glucoside (x=1 to 4) which can in turn be reacted with a longer chain alcohol (R 2 OH) to displace the short chain alcohol and obtain the desired alkyl polyglucoside. If this two step procedure is used, the short chain alkylglucosde content of the final alkyl polyglucoside material should be less than 50%, preferably less than 10%, more preferably less than about 5%, most preferably 0% of the alkyl polyglucoside.

The amount of unreacted alcohol (the free fatty alcohol content) in the desired alkyl polysaccharide surfactant is preferably less than about 2%, more preferably less than about 0.5% by weight of the total of the alkyl polysaccharide. For some uses it is desirable to have the alkyl monosaccharide content less than about 10%.

The used herein, “alkyl polysaccharide surfactant” is intended to represent both the preferred glucose and galactose derived surfactants and the less preferred alkyl polysaccharide surfactants. Throughout this specification, “alkyl polyglucoside” is used to include alkyl polyglycosides because the stereochemistry of the saccharide moiety is changed during the preparation reaction.

An especially preferred APG glycoside surfactant is APG 625 glycoside manufactured by the Henkel Corporation of Ambler, Pa. APG25 is a nonionic alkyl polyglycoside characterized by the formula:

C n H 2n+1 O(C 6 H 10 O 5 ) x H

wherein n=10 (2%); n=122 (65%); n=14 (21-28%); n=16 (4-8%) and n=18 (0.5%) and x (degree of polymerization)=1.6. APG 625 has: a pH of 6 to 10 (10% of APG 625 in distilled water); a specific gravity at 25° C. of 1.1 g/ml; a density at 25° C. of 9.1 lbs/gallon; a calculated HLB of 12.1 and a Brookfield viscosity at 35 C., 21 spindle, 5-10 RPM of 3,000 to 7,000 cps.

The C 12 -C 14 fatty acid alkanolamides can be optionally included in the instant compositions at a concentration of 0.1 wt. % to 10 wt. %.

wherein n is about 8 to about 225, more preferably about 10 to about 100,000, wherein the polyethylene glycol has a molecular weight of about 200 to about 1,000. One preferred polyethylene glycerol is PEG1000 which is a polyethylene glycol having a molecular weight of about 1000.

The instant composition can optionally contain 0.05 wt. % to 4 wt. % of a proton donating agent is selected from the group consisting of inorganic acids such as sulfuric acid and hydrochloric acid and hydroxy containing organic acid, preferably a hydroxy aliphatic acid, wherein the hydroxy contains organic acid is selected from the group consisting of lactic acid, citric acid, orthohydroxy benzoic acid and glycolic acid and mixtures thereof.

The water is present in the composition at a concentration of about 5 wt. % to 70 wt. %.

The cleaning composition of this invention may, if desired, also contain other components either to provide additional effect or to make the product more attractive to the consumer. The following are mentioned by way of example: Antibacterial agents such as 2,4,4′-trichloro-2′hydroxydiphenyl ether colors or dyes in amounts up to 0.5% by weight; pH adjusting agents, such as sulfuric acid or sodium hydroxide, can be used as needed.

Preservatives which can be used in the instant compositions at a concentration of 0.005 wt. % to 3 wt. %, more preferably 0.01 wt. % to 2.5 wt. % are: benzalkonium chloride; benzethonium chloride,5-bromo-5-nitro-1,3dioxane; 2-bromo-2-nitropropane-1,3-diol; alkyl trimethyl ammonium bromide; N-(hydroxymethyl)-N-(1,3-dihydroxy methyl-2,5-dioxo-4-imidaxolidinyl-N′-(hydroxy methyl) urea; 1-3-dimethyol-5,5-dimethyl hydantoin; formaldehyde; iodopropynl butyl carbamata, butyl paraben; ethyl paraben; methyl paraben; propyl paraben, mixture of methyl isothiazolinone/methyl-chloroisothiazoline in a 1:3 wt. ratio; mixture of phenoxythanol/butyl paraben/methyl paraben/propylparaben; 2-phenoxyethanol; tris-hydroxyethyl-hexahydrotriazine; methylisothiazolinone; 5-chloro-2-methyl-4-isothiazolin-3-one; 1,2-dibromo-2,4-dicyanobutane; 1-(3-chloroalkyl)-3,5,7-triaza-azoniaadamantane chloride; and sodium benzoate. PH adjusting agents such as sulfuric acid or sodium hydroxide can be used as needed.

The product of the present invention comprises a water insoluable substrate with one or more layers. Each layer may have different textures and abrasiveness. Differing textures can result from the use of different combinations of materials or from the use of different manufacturing processes or a combination thereof. A dual texture substrate can be made to provide the advantage of a more abrasive side for cleaning difficult to remove soils. A softer side can be used for fine dishware and flatware. The substrate should not dissolve or break apart in water. It is the vehicle for delivering the cleaning composition to dishware, flatware, pots and pans. Use of the substrate enhances lathering, cleaning and grease removal.

A wide variety of materials can be used as the substrate. It should have sufficient wet strength, abrasivity, loft and porosity. Examples include, non woven substrates, wovens substrates, hydroentangled substrates and sponges.

Examples of suitable non woven water insoluable substrates include, 100% cellulose Wadding Grade 1804 from Little Rapids Corporation, 100% polypropylene needlepunch material NB 701-2.8-W/R from American Non-wovens Corporation, a blend of cellulosic and synthetic fibres-Hydraspun 8579 from Ahlstrom Fibre Composites, and &0% Viscose/30% PES Code 9881 from PGI Nonwovens Polymer Corp.

Another useful substrate is manufactured by Jacob Holm-Lidro Rough. It is a composition material comprising a 65/35 viscose rayon/polyester hydroentangled spunlace layer with a hydroenlongated bonded polyeser scribbly layer.

Still another useful substrate is manufactured by Texel “TI”. It is a composite material manufactured from a layer of coarse fiber 100% polypropylene needlepunch, an absorbent cellulose core and a fine fiber polyester layer needlepunched together. The polypropylene layer can range from 1.5 to 3.5 oz/sq. yd. The cellulose core is a creped paper layer ranging from 0.5 to 2 oz./sq. yd. The fine fiber polyester layer can range from 0.5 to 2 oz./sq. yd.

Still another composite material manufactured by Texcel from a layer of coarse fiber 100% polypropylene needlepunch layer, an absorbent cellulose core and a fine fiber polyester layer needlepunched together. The polypropylene layer can range from 1.5 to 3.5 oz/sq. yd. The cellulose core is a creped paper layer ranging from 0.5 to 2 oz/sq. yd. The fine fiber polyester layer can range from 0.5 to 2 oz/sq. yd. The polypropylene layer is flame treated to further increase the level of abrasivity. The temperature of the flame and the length of time the material is exposed can be varied to create different levels of surface roughness.

The abrasiveness is tested by cutting one quarter inch thick Lucite boards to fit an abrader bed. The boards are marked to indicate the track of the wipes during abrasion (approximately 2¼ and 4½ inches from one long edge) and three spots along the track (6, 9 and 12 inches from the short end). This gives unique and reproducible locations at which to do gloss measurements which are in the center of the abrasion track.

Using a BYK-Gardener Haze-Gloss glossmeter, the indicated spots are measured for starting gloss. An average and standard deviation is reported for each track using the three measurements.

Pieces of the wipes are cut approximately 3 inches by 2 inches. This piece is wrapped around a piece of sponge that fits in a holder for the abrader. (Indication should be made of whether the material is being used in the machine or cross direction). This wrapped sponge is placed in the holder, tucking all the edges of the wipe into the holder so that it is kept firmly in place. The dry sponge is wetted with approximately 20-25 g of water (either deionized, distilled or tap as the experiment desires). This is done so that there are two wipes in the trial.

The gloss measured Lucite board is placed in the abrader bed. Set the abrader for 500 cycles and start.

After the abrader cycles have ended, the Lucite board is removed. It is wiped dry with paper towel to remove any residual water. It is also inspected for any fingerprints incurred during handling and these are also wiped clean. Remeasure the gloss at the specified spots again and again report the average of these three spots and the standard deviation for each track.

The higher the abrasiveness of the wipe, the more that it roughens the surface of the Lucite and the more the gloss is reduced. The most abrasive of the wipes therefore give the greatest decrease in gloss. Results for this test are given below.

                                 Change in Gloss
Material (all machine direction) for 500 cycles
3 layer needlepunch (Texel) no flame treatment 0
3 layer needlepunch (Texel) medium flame treatment 4
3 layer needlepunch (Texel) high flame treatment 19
