Description

DETERGENT COMPOSITION COMPRISING ANTI-HAZING AGENT

TECHNICAL FIELD

This application relates to detergent compositions containing an anti-hazing agent.

The detergent composition cleaning solution is also preferably suitable for use with a disposable cleaning pad. This application also relates to a process of using the detergent composition with such a cleaning pad, and the provision of a kit containing the detergent composition and cleaning pad are disclosed.

BACKGROUND OF THE INNENTION

The developer and formulator of surfactants for hard surface cleaning must consider a wide variety of possibilities with limited (sometimes inconsistent) information, and then strive to provide overall improvements in one or more of a whole array of criteria, including performance in the presence of free calcium and a wide variety of soils, in complex mixtures of surfactants and polymers, e.g. cationic polymers, formulation changes, enzymes , various changes in consumer habits and practices, and the need for biodegradability.

One problem associated with hard surface cleaning compositions is the hazing of a surface after cleaning. This hazing is often associated by the consumer with residual soil, or unremoved stains. The hazing is usually the result of solution components combining with visible residues of any unremoved soil. These residues, when dried on a hard surface, such as a floor, can refract light instead of reflecting it and diminish the appearance of the surface. When haze is present after cleaning the consumer perception is that more product should be used or that the product does not work. Consequently, there remains the need for a hard surface cleaning composition suitable for providing grease and particulate soil removal which upon drying on a surface minimizes or totally eliminates haze .

SUMMARY OF THE INNENTION It has now been determined that the use of certain anti-hazing agents, as outlined in detail below, in combination with at least one surfactant in a specific ratio range and pH provide a composition which upon drying does reduce haze.

In accordance with a first aspect of the present invention a hard surface detergent composition is provided that comprises: an effective amount of anti-hazing agent, preferably from about 0.001% to about 5%, more preferably from about 0.001% to about 2%, by weight of the composition of anti-hazing agent. The anti-hazing agent being selected from the group consisting of organic diamine, having molecular weight of from greater than 61 g/mol to less than or equal to 400 g/mol, organic triamine having molecular weight less than or equal to 500 g/mol, organic tetramine having molecular weight less than or equal to 600 g/mol, and mixtures thereof, and wherein the anti-hazing agent has a pKa of at least about 8; and an effective amount, preferably from about 0.005% to about 0.5%, more preferably from about 0.01% to about 0.2% by weight of the composition of one or more detergent surfactants; wherein the weight ratio of the anti- hazing agent to the surfactants is from about 40: 1 to about 1:5, preferably from about 15:1 to about 1 :5, more preferably from about 11 : 1 to about 1 :5; and said composition has a pH greater than about 8, preferably greater than 9, more preferably from 9.5 to 12.5, more preferably from about 9.5 to about 11.7.

In accordance with a second aspect of the present invention a process of cleaning a surface comprises the step of applying an effective amount of the detergent composition according to the first aspect to said surface and. optionally, but preferably, absorbing the composition in an absorbent structure preferably comprising a superabsorbent material.

In accordance with a third aspect of the present invention a kit comprises an implement containing disposable cleaning pad containing superabsorbent material and detergent composition that provides effective cleaning and good filming/streaking, that is reduces hazing, when used with said disposable cleaning pad, optionally, but preferably, without rinsing, said composition according to the first aspect comprising an effective amount of anti-hazing agent. The anti-hazing agent being selected from the group consisting of organic diamine, having molecular weight of from greater than 61 g/mol to less than or equal to 400 g/mol, organic triamines having molecular weight less than or equal to 500 g/mol, organic tetramines having molecular weight less than or equal to 600 g/mol, and mixtures thereof, the anti-hazing agent having a pKa of at least about 8; and an effective amount of one or more detergent surfactants; wherein the weight ratio of said anti-hazing agent to said surfactants is from about 40:1 to about 1:5, preferably from about 15: 1 to about 1 :5, more preferably from about 11:1 to about 1 :5; and said composition has a pH greater than about 8, preferably greater than 9, more preferably from 9.5 to 12.5, more preferably from about 9.5 to about 11.7.

The invention in a fourth aspect also comprises a detergent composition as disclosed herein in a container in association with instructions to use it with an implement comprising a disposable pad, preferably a disposable pad comprising an effective amount of a superabsorbent material, and, optionally, said container is in a kit comprising disposable pad and, optionally, the remainder of said implement, or, at least, a disposable cleaning pad comprising a superabsorbent material. The invention also relates in a preferred fifth aspect to the use of the composition and a cleaning pad comprising a superabsorbent material (superabsorbent pad) to effect cleaning of soiled surfaces.

Accordingly, it is an aspect of the present invention to provide novel cleaning compositions; methods of using these novel compositions; kits containing these novel compositions; methods of using these novel compositions/ and these novel compositions packaged with instructions for using them in a way that provides unique benefits to the consumer. These, and other, aspects, features and advantages will be clear from the following detailed description and the appended claims. In the description of the invention various embodiments and/or individual features are disclosed. As will be apparent for the skilled practitioner all combinations of such embodiments and features are possible and can result in preferred executions of the invention.

All parts, percentages and ratios used herein are by weight unless otherwise specified. All documents cited are, in relevant part, incorporated herein by reference.

DETAILED DESCRIPTION The present invention relates to hard surface cleaning applications (HSC). HSC compositions are different form other similar cleaning compositions, such as LDL's or laundry compositions, in that they are tpyically used neat or pre-diluted, low suds (unlike LDL's), non-rinse, higher pH. Furthermore, HSC compositions are designed to be applied to much larger surfaces, than other cleaning compositions, such as counter tops, and floors. They are also applied to a wide variety of both synthetic and natural surfaces, such as marble, slate, vinyl, linoleum, granite, Formica, aluminum, stainless steel and the like. Anti-hazing agent The anti-hazing agent of the present invention is selected from the group consisting of organic diamines, having molecular weights of from greater than 61 g/mol to less than or equal to about 400 g/mol; organic triamines having molecular weight less than or equal to about 500 g/mol; organic tetramines having molecular weight less than or equal to about 600 g/mol; and mixtures thereof, and wherein said anti-hazing agent has a pKa of at least about 8.

As a working definition herein, the pKa of the anti-hazing agent is specified in an all-aqueous solution at 25°C and for an ionic strength between 0.1 to 0.5 M. The pKa is an equilibrium constant which can change with temperature and ionic strength; thus, values reported in the literature are sometimes not in agreement depending on the measurement method and conditions. To eliminate ambiguity, the relevant conditions and/or references used for pKa's of this invention are as defined herein or in "Critical Stability Constants: Volume 2, Amines". One typical method of measurement is the potentiometric titration of the acid with sodium hydroxide and determination of the pKa by suitable methods as described and referenced in "The Chemist's Ready Reference Handbook" by Shugar and Dean, McGraw Hill, NY, 1990.

It is preferred that when the anti-hazing agent is an organic diamine it has the formula:

R_s ^R

^VN-X-N'

R R wherein each R is independently selected from the group consisting of hydrogen, Cι-C linear or branched alkyl, alkyleneoxy having the formula: (R2O)_yR3

wherein R^" is C₂-C linear or branched alkylene, and mixtures thereof; R³ is hydrogen, Cι-C alkyl, and mixtures thereof; y is from 1 to about 10; X is a unit selected from: i) C₂-Cιo linear alkylene, C -Cιo branched alkylene, C -Cιo cyclic alkylene, C₃- Cio branched cyclic alkylene, an alkyl eneoxyalkylene having the formula:

wherein R and y are the same as defined herein above; ii) C -Cιo linear, C -Cιo branched linear, C -Cιo cyclic, C -Cιo branched cyclic alkylene, C-₅-C10 arylene, wherein said unit comprises one or more electron donating or electron withdrawing moieties which provide said diamine with a pKa greater than about 8; and iii) mixtures of (i) and (ii). More preferably the anti-hazing agent is selected from the group consisting of 1,3- bis(amino methyl)-cyclohexane(also known as 1, 3 cyclohexaneBis(methylamine) or 1, 3 BAC), N-cyclohexyl-l,3-propanediamine, 1,2-diaminocyclohexane, 1, 3 cyclohexane Bis[tetra(hydoxypropyl)-methylamine], 1,3 benzene dimethanamine, N-phenylethylene diamine, 1,3 bis[tris(hydroxymethyl)-methylamino]propane, N,N,N',N'tetrakis(2- hydroxypropyl)ethylenediamine, N.N'-bis bishydroxypropy ethylene diamine, N,N^Λ- bis(bishydroxyethyll)ethylene diamine, N,N',N'tetrakis(2-hydroxyethyl)ethylenediamine, 1,3, Bis[tris(hydroxymethyl)methylamino]propane, 1,3 benzene dimethanamine, and mixtures thereof. Even more preferably the anti-hazing agent is l,3-bis(amino methyl)- cyclohexane, N,N,N',N'tetrakis(2-hydroxypropyl)ethylenediamine, N,N',N'tetrakis(2- hydroxyethyl)ethylenediamine, N,N,N',N'tetrakis(2-hydroxypropyl)ethylenediamine.

N,N'-bis(bishydroxypropyl)ethylene diamine, N^-bis ishydroxyethyOethylene diamine, 1 ,3 benzene dimethanamine and mixtures thereof.

The anti-hazing agent can provide additional functions and/or benefits. The preferred anti-hazing agents provide alkalinity, especially to provide a pH of greater than about 8, preferably greater than about 9, and more preferably from about 9.5 to about 12.5, even more preferably from about 9.5 to about 11.7 to improve cleaning, stabilize the formula, and/or neutralize anionic materials like surfactants and carboxylate polymers that are present. The preferred anti-hazing agents, for example, l,3-bis(amino methyl)- cyclohexane, in addition to providing improved cleaning and product stability help reduce the incidence of, or severity of marks on the floor after cleaning the surface with a composition according to the present invention. In addition, the preferred amines have surprisingly low odor compared to other amines, which allow them to be used at relatively higher levels in compositions while maintaining consumer-acceptable odor characteristics in the finished product. These extra benefits can be brought to the attention of consumers by adding instructions as pointed out herein after. Surfactant

The compositions of the present invention contain one or more detergent surfactants. It is preferred that these surfactants are selected from the group consisting of anionic, nonionic, zwitterionic, cationic, amphoteric and mixtures thereof, more preferably the detergent surfactant has a linear or branched structure and is selected from the group consisting of anionic and nonionic detergent surfactants, even more preferably anionic and nonionic detergent surfactants having hydrophobic chains containing from about 8 to about 18, preferably from about 8 to about 15, carbon atoms. Examples of anionic surfactants include, but are not limited to, linear alkyl sulfates, alkyl sulfonates, and the like. Examples of nonionic surfactants include alkylethoxylates and the like. Examples of zwitterionic surfactants include betaines and sulfobetaines. Examples of amphoteric surfactants include alkylampho glycinates, and alkyl imino propionate. Further example of suitable surfactants are described in McCutcheon's Vol. 1 : Emulsifiers and Detergents, North American Ed., McCutheon Division, MC Publishing Co., 1995, which is incorporated herein by reference

Highly preferred surfactants include alcohol ethoxylate detergent surfactant (e.g., Neodol 1-5®, available from Shell Chemical Co.) and an alkyl sulfonate (e.g., Witconate NAS-8, a linear Cg sulfonate available from Witco Co.) and mixtures thereof. Soil Suspending Agents The hard surface cleaning compositions of the present invention can optionally

(preferably) include a soil suspending agent. The soil suspending agents, preferably water soluble polymers, for use in the detergent composition and/or cleaning solution of this invention are preferably 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 January 2, 1990, entitled Detergent compositions containing ethoxylated amines having, clay soil removal/anti- redeposition properties, by Vander Meer, James M.

Preferred ethoxylated polyamines can be derived from polyamino amides and/or polyaminopropyleneoxide materials. Preferred ethoxylated amine polymers are the ethoxylated C₂ -C polyalkyleneamines and polyalkyleneimines. Particularly preferred ethoxylated polyalkyleneamines and polyalkyleneimines are the ethoxylated polyethyleneamines (PEAs) and polyethyleneimines (PEIs). Each hydrogen atom attached to each nitrogen atom represents an active site for subsequent ethoxylation. Preferred have a molecular weight of from about 140 to about 310, preferably from about 140 to about 200. These PEAs can be obtained by reactions involving ammonia and ethylene dichloride, followed by fractional distillation. The common PEAs obtained are tri ethyl enetetramine (TETA) and tetraethylenepentamine (TEPA). Above the pentamines, i.e., the hexamines, heptamines, octamines and possibly nonamines, the cogenerically derived mixture does not appear to separate by distillation and can include other materials such as cyclic amines and particularly piperazines. There can also be present cyclic amines with side chains in which nitrogen atoms appear. See U.S. Pat. No. 2,792,372 to Dickson, issued May 14, 1957, which describes the preparation of PEAs. The minimum degree of ethoxylation required for preferred soil suspension performance can vary depending upon the number of units in the PEA.

The PEIs used in preparing the compounds of the present invention have a molecular weight of at least about 600 prior to ethoxylation, which represents at least about 10 units. Preferred PEIs used in preparing these compounds have an average molecular weight of from about 600 to about 2600. Although linear polymer backbones are possible, branched chains can also occur. The relative proportions of primary, secondary and tertiary amine groups present in the polymer can vary, depending on the manner of preparation. Each hydrogen atom attached to each nitrogen atom of the PEI represents an active site for subsequent ethoxylation. These PEIs can be prepared, for example, by polymerizing ethyleneimine in the presence of a catalyst such as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc. Specific methods for preparing PEIs are disclosed in U.S. Pat. No. 2,182,306 to Ulrich et al., issued Dec. 5, 1939; U.S. Pat. No. 3,033,746 to Mayle et al., issued May 8, 1962; U.S. Pat. No. 2,208,095 to Esselma-nn et al., issued July 16, 1940; U.S. Pat. No. 2,806,839 to Crowther, issued Sept. 17, 1957; and U.S. Pat. No. 2,553,696 to Wilson, issued May 21, 1951 (all incorporated herein by reference). The minimum degree of ethoxylation required for suitable soil suspension performance can increase as the molecular weight of the PEI increases, especially much beyond about 1800. Also, the degree of ethoxylation for preferred compounds increases as the molecular weight of the PEI increases. For preferred PEAs and PEIs having a molecular weight of at least about 600, the degree of ethoxylation is preferably at least about 1, with a more preferred range of from about 12 to about 42. For PEAs and PEIs having a molecular weight of at least 1600, the degree of ethoxylation is preferably at least about 2, with a typical range of from about 10 to about 40. The level at which the ethoxylated amine(s) can be present in the detergent compositions herein can vary depending upon the compounds used. Generally, the ethoxylated amines can be included in an amount of from about

0.001% to about 1% by weight of the composition, with the preferred range being from about 0.005% to about 0.5% by weight, and a more preferred range of about 0.01% to 0.1%.

Still other suitable compounds are disclosed in U. S. Pat. Patent Number 5,565,145, issued October 15, 1996, entitled Compositions comprising ethoxylated/propoxylated, polyalkyleneamine polymers as soil dispersing agents, by Watson, Randall A.; Gosselink, Eugene P.; and Zhang, Shulin, incorporated herein reference.

These compounds are ethoxylated/propoxylated polyalkyleneamine polymers The polyalkyleneamines comprise a nitrogen-containing backbone with an average molecular weight of from about 600 to about 10,000, preferably from about 1,000 to about 3,000.

An example of suitable polyalkylamine has the general formula:

E B

I I

[E₂NCH₂CH₂]_W [NCH₂CH₂]_X [NCH₂CH₂]_y NE₂ wherein B is a continuation by branching of the polyethyleneimine backbone and E is an ethyleneoxy unit having the formula:

-(CHzCH.O^H wherein m has an average value of about 20. What is meant herein by an average value of 20 is that sufficient ethylene oxide or other suitable reagent is reacted with the polyethyleneimine starting material to fully ethoxylate each N-H unit in the polyethyleneamine to an average degree of 20 ethoxy groups.

The units which make up the polyalkyleneimine backbones are derived from primary amine units having the formula:

[H₂N-CH₂CH₂]- and -NH₂ which terminate the main backbone and any branching chains, secondary amine units having the formula:

H [N-CH₂CH₂]— and which, after modification, have their hydrogen atom substituted by an average of 20 ethyleneoxy units, and tertiary amine units having the formula:

B — [N-CH₂CH₂]— which are the branching points of the main and secondary backbone chains, B representing a continuation of the chain structure by branching. The tertiary units have no replaceable hydrogen atom and are therefore not modified by substitution with ethyleneoxy units. During the formation of the polyamine backbones cyclization may occur, therefore, an amount of cyclic polyamine can be present in the parent polyalkyleneimine backbone mixture. Each primary and secondary amine unit of the cyclic alkyleneimines undergoes modification by the addition of alkyleneoxy units in the same manner as linear and branched polyalkyleneimines. The indices w, x, and y have values such that the average molecular weight of the polyethyleneimine backbone prior to modification is about 600 daltons. In addition, those skilled in the art will recognize that each branch chain must terminate in a primary amine unit, therefore the value of the index w is y + 1 in the case where no cyclic amine backbones are present. The average molecular weight for each ethylene backbone unit, - NCH2CH2-, is approximately 43 daltons.

Other soil suspending materials include polyvinyl pyrrolidone and/or cellulose derivatives. Polyvinyl pyrrolidone is not a single individual compound but can be obtained in almost any degree of polymerization. The degree of polymerization, which is most easily expressed in terms of average molecular weight, is not critical provided the material has the desired water solubility and soil-suspending power. In general, suitable soil-suspending vinyl pyrrolidone polymers are linear in structure, and have an average molecular weight within the range of about 5,000 to about 100,000, and preferably from about 15,000 to about 50,000. Suitable polymers will also, generally, have a water solubility of greater than 0.3% at normal usage temperatures.

Any well-known nonionic cellulose ether can be used in the detergent composition according to the invention. Preferably the cellulose ether is an alkyl or an alkyl/ hydroxyalkyl cellulose derivative. The alkyl group should contain from 1 to 4, preferably from 1 to 3 carbon atoms, and the hydroxyalkyl group should contain from 2 to 4, preferably from 2 to 3 carbon atoms. Particularly preferred materials include methyl hydroxyethyl cellulose, methyl hydroxylpropyl cellulose and ethyl hydroxyethyl cellulose. The total level of the polyvinyl pyrrolidone and/or cellulose derivatives in the detergent composition is preferably in the range of about 0.001% to about 1% by weight of the composition, a more preferred range being from about 0.005% to about 0.5% by weight, and a more preferred range of about 0.01 % to 0.1 %.

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. Other soil suspending agents can be anionic polymers. Examples of these anionic polymers are disclosed in, e.g., U. S. Pat. Number: 5789369, entitled, Modified polyacrylic acid polymers for anti-redeposition performance, by Gopalkrishnan, Sridhar; Guiney, Kathleen M.; and Sherman, John V. The total molecular weight of the copolymer disclosed in said patent are within the range of about 1000 to 100,000, as determined by gel permeation chromatography. More preferably, the weight average molecular weight falls within the range of about 1,000 to 30,000; most preferably within the range of about 1,000 to 20,000.

The hydrophilic copolymer can be prepared by copolymerizing two monomers, an unsaturated hydrophilic monomer and a hydrophilic oxyalkylated monomer. Examples of unsaturated hydrophilic monomers disclosed include acrylic acid, maleic acid, maleic anhydride, methacrylic acid, methacrylate esters and substituted methacrylate esters, vinyl acetate, vinyl alcohol, methylvinyl ether, crotonic acid, itaconic acid, vinyl acetic acid, and vinylsulphonate. The unsaturated hydrophilic monomer component of the hydrophilic copolymer is preferably acrylic acid. Examples of the hydrophilic oxyalkylated monomer include compounds that have a polymerizable olefinic moiety with at least one acidic hydrogen and are capable of undergoing addition reaction with alkylene oxide. It is also possible to include monomers with at least one acidic hydrogen that are polymerized first, and then subsequently oxyalkylated to yield the desired product. For example, allyl alcohol is especially preferred since it represents a monofunctional initiator with a polymerizable olefinic moiety having an acidic hydrogen on the oxygen, and is capable of adding to alkylene oxide. Other examples of the hydrophilic oxyalkylated monomer of the copolymer include reaction products of either acrylic acid, methacrylic acid, maleic acid, or 3-allyloxy-l,2-propanediol with alkylene oxide. Preparation of oxyalkylated monomers is disclosed in U.S. Pat. No. 5,162,475 and U.S. Pat. No. 4,622,378 both incorporated herein by reference. Especially preferred is the hydrophilic oxyalkylated monomer which is a propylene Is oxide and ethylene oxide adduct of allyl alcohol. This monomer has a molecular weight of about 3800. The molecular weight of the hydrophilic oxyalkylated monomer according to the various embodiments of the invention should be preferably within the range of about 600 to 30,000, more preferably about 700 to 15,000, and most preferably about 700 to 5000. The hydrophilic oxyalkyated monomer preferably has a solubility of about 500 grams/liter, more preferably about 700 grams/liter in water.

Other polymeric polycarboxylates that are suitable include, for example, the polymers disclosed in U. S. Pat. 5,574,004, incorporated herein by reference. Such polymers include homopolymers and/or copolymers (composed of two or more monomers) of an alpha, beta-ethylenically unsaturated acid monomer such as acrylic acid, methacrylic acid, a diacid such as maleic acid, itaconic acid, fumaric acid, mesoconic acid, citraconic acid and the like, a monoester of a diacid with an alkanol, e.g., having 1-8 carbon atoms, and mixtures thereof. When the polymeric polycarboxylate is a copolymer, it can be a copolymer of more than one of the foregoing unsaturated acid monomers, e.g., acrylic acid and maleic acid, or a copolymer of at least one of such unsaturated acid monomers with at least one non-carboxylic alpha, beta-ethylenically unsaturated monomer which can be either relatively non-polar such as styrene or an olefinic monomer, such as ethylene, propylene or butene-1, or which has a polar functional group such as vinyl acetate, vinyl chloride, vinyl alcohol, alkyl acrylates, vinyl pyridine, vinyl pyrrolidone, or an amide of one of the delineated unsaturated acid monomers, such as acrylamide or methacrylamide. Certain of the foregoing copolymers can be prepared by after treating a homopolymer or a different copolymer, e.g., copolymers of acrylic acid and acrylamide by partially hydrolyzing a polyacrylamide. Copolymers of at least one unsaturated carboxylic acid monomer with at least one non-carboxylic co-monomer should contain at least about 50 mol % of polymerized carboxylic acid monomer. The polymeric polycarboxylate should have a number average molecular weight of, for example about 1000 to 10,000, preferably about 2000 to 5000. To ensure substantial water solubility, the polymeric polycarboxylate is completely or partially neutralized, e.g., with alkali metal ions, preferably sodium ions.

The total level of the polymeric polycarboxylate in the detergent composition is preferably in the range of about 0.001% to about 1% by weight of the composition, a more preferred range being from about 0.005% to about 0.5% by weight, and a more preferred range of about 0.01% to 0.1%. Still other polycarboxylate materials include those disclosed in U. S. Pat. Patent

Number: 5,470,510, issued November 28, 1995, entitled Dispersing agent, by Willey, Alan D. The polymers can be derived from L-glumatic acid, D-glumatic acid or mixtures, e.g. racemates, of these L and D isomers. The L isomer and D, L racemate are currently preferred. The polymers include not only the homopolymers of glutamic acid but also copolymers, such as block, graft or random copolymers, containing glutamic acid. Thus, copolymers of glutamic acid with at least one other (preferably biodegradable) monomer, oligomer or polymer come into consideration. These include, for example, copolymers containing at least one other amino acid, such as aspartic acid, ethylene glycol, ethylene oxide, (or an oligymer or polymer of any of these) or polyvinyl alcohol. Glutamic acid can, of course, carry one or more substituents and the polymers useful as component (a) include those in which a proportion or all of the glutamic acid monomers are substituted. Substituents include, for example, alkyl, hydroxy alkyl, aryl and arylalkyl, commonly with up to 18 carbon atoms per group, or polyethylene glycol attached by ester linkages.

Other soil suspending agents suitable herein include cellulose derivatives such as methylcellulose, carboxymethylcellulose and hydroxyethylcellulose. The total level of cellulose derivatives in the detergent composition is preferably in the range of about 0.001% to about 1% by weight of the composition, a more preferred range being from about 0.005% to about 0.5% by weight, and a more preferred range of about 0.01% to 0.1%.

Further useful organic polymeric compounds are the polyethylene glycols, particularly those of average molecular weight of 1,000-100,000, more particularly 2000 to 10,000 and most preferably 4,000. These can be used alone or in combination with the polycarboxylate polymers disclosed herewithin. The total level of these polymers in the detergent composition is preferably in the range of about 0.001% to about 1% by weight of the composition, a more preferred range being from about 0.005%) to about 0.5% by weight, and a more preferred range of about 0.01% to 0.1%.

Further examples of suitable soil suspending agent can be found in co-pending U.S. Patent Application Serial No. 60/110,356, filed December 1, 1998 K. W. Willman, et al. (P&G Case 7367P) which is incorporated by reference herein. Hydrophilic Polymer For the purpose of helping to level the solution during drying the composition preferably contains a polymer that has hydrophilic and shear-thinning characteristics that is capable of inhibiting molecular aggregation of surfactant solution on floors during the dry-down process to provide one, or more, of the benefits of: strippability; avoidance of build-up; easy spreading of solution on hard surfaces such as floors; and maintaining a sufficient amount of water on the surface to level the ingredients remaining on the surface. By leveling we mean minimizing solution de-wetting from the surface during drying which, in turn, minimizes streaking. Because of this benefit, the polymer allows formulation at even low surfactant levels and allows for addition of solvents to aid in cleaning without hurting filming/streaking.

When present in the composition the hydrophilic, shear-thinning polymer that is capable of inhibiting molecular aggregation of surfactant solution on floors during the dry-down process, is present in an amount of from about 0.0001% to about 0.2%, more preferably from about 0.0001% to about 0.1%, even more preferably from about 0.0005% to about 0.08%, by weight of the composition. It is preferred that hydrophilic, shear- thinning polymer has a molecular weight of at least about 100,000, preferably at least about 1,000,000.

Preferably the hydrophilic, shear-thinning polymer is selected from the group of polymers consisting of xanthan gum, guar gum, gum arabic, pectin and mixtures thereof, preferably xanthan gum.

Further examples of suitable hydrophilic, shear-thinning polymer can be found in co-pending U.S. Patent Application Serial No. 60/061,296, filed October 7, 1997 by N. J. Policicchio, et al. (P&G Case 6873P), which is incorporated by reference herein. Suds Suppressor
