METHODS OF TREATING SURFACES USING SURFACE-TREATING COMPOSITIONS CONTAINING SULFONATED/CARBOXYLATED POLYMERS

TECHNICAL FIELD This invention is in the field of treating surfaces with cleaning and/or rinsing compositions. More particularly, the invention relates to surface-treating compositions, methods, and compositions of matter, and articles of manufacture containing a water- soluble, sulfonated/carboxylated polymer.

BACKGROUND OF THE INVENTION In certain surface-treating compositions and methods, polymers may serve many useful functions. They can function, either independently or concurrently, as thickeners in liquid detergents, as viscosity reducers in the processing of granular detergents, as anti- redeposition agents, as scale and deposit inhibitors, as crystal modifiers, and as detergent assistants which are capable of completely or partially replacing the materials used as builders, while imparting to surfactants optimum properties with respect to detergent actions. In certain applications, use of polycarboxylate polymers may help to reduce hard water filming on substrate surfaces. These polycarboxylate polymers may be derived from (meth)acrylic acids and salts, as well as, from mixtures of such polymers with other compounds and/or polymers, such as phosphonic acids. Copolymers of (meth)acrylic acids and vinyl esters (such as, methyl methacrylate (MMA), ethyl acrylate (EA), hydroxy ethyl methacrylate and hydroxy propyl acrylate), copolymers of (meth)acrylic acids and salts with acrylamido alkyl, aryl sulfonates, or unsubstituted acrylamides, and terpolymers, formed from acrylic acid, 2-acrylamido-2-methyl propane sulfonic acid (AMPS) or unsubstituted acrylamide, are also useful in automatic dishwashing compositions. Polymers comprising polycarboxylates are described in U.S. Pat. Nos. 4,745,154; 5,547,612; and 5,591,703. Recently, several hydrophobic polymers have been developed and are described in U.S. Pat. Nos. 5,489,397; 5,021,525; 5,534,198; 5,698,512; 5,798,324; 6,395,185; 6,114,294; 4,711,725; and 6,395,185. Sulfonated/carboxylated polymers may exhibit greater levels of hydrophobicity than that seen in conventional polycarboxylates polymers, however, these polymers may be expensive to manufacture, and especially with a high degree of sulfonation (e.g. 4 mole % and greater). With regard to the use of some nonionic, amide- and ester-containing monomers in certain automatic dishwashing compositions, this can be actually very problematic. For example, some MMA-containing or AMPS-containing sulfonated/carboxylated polymers are unstable in chlorinated liquid automatic dishwashing compositions (especially in gels having a high pH) — often losing their performance after a couple of weeks in solution. While not wishing to be bound by theory, it is believed that in certain automatic washing detergents these polymers may be subject to attack by chlorine bleach because of the presence of the nitrogen in the amido functionality (such as, in AMPS) or the hydrolysis of the ester linkage (such as, in MMA). Thus, there remains a long-standing need for surface-treating compositions that comprise more cost-effective polymers. The sulfonated/carboxylated polymers described herein can be used to clean and/or rinse a variety of hard surfaces with good cleaning performance while having less filming, spotting, and/or streaking. For example, these polymers can be used in automatic dishwashing rinse aid compositions, including but not limited to acidic formulations, to help to reduce hard water filming and spotting on tableware surfaces. In some liquid hard surface cleaners (such as, medium-duty detergent compositions or light-duty liquid dishwashing detergents), these polymers can act as an effective hydrotrope to reduce filming and streaking on all types of bathroom and kitchen surfaces, such as tableware, countertops, appliances, fixtures, floors, walls, windows, mirrors, shower doors, etc. These polymers may also be used in other acidic formulations, for example, to clean and/or rinse car surfaces. Since the sulfonated/carboxylated polymers described herein may contain low sulfonate functionality, they can be more cost-effective than conventional sulfonated/carboxylated polymers with higher sulfonation. When used in a variety of consumer products, these cost-effective polymers provide many consumer benefits. For example, these polymers can be used as processing aids during blending, drying and agglomerating operations, thereby providing uniform distribution of the detergent composition's components, desired particle size and density, as well as, other desirable attributes during manufacture and storage of detergents, especially in powdered detergents (such as, detergent tablets, granulated compact detergents, granulated automatic dishwashing detergents, and heavy-duty granulated or granular laundry detergents). Since sulfonated/carboxylated polymers with low sulfonation also provide improved stability performance in the presence of chlorine bleach, they are ideally suited for certain chlorinated and/or highly alkaline detergent compositions (such as liquid or granular, dishwashing detergents and heavy-duty laundry detergents). In the wash liquor, these polymers are believed to perform as a dispersant, co-builder and anti-soil redeposition agent, for both hard surfaces (e.g. tableware) and soft surfaces (e.g. laundry). These polymers are also believed to improve detergency by acting as a co-builder in reducing soil redeposition and water hardness salt deposition in soft surface cleaning applications, as well as, to function as a dispersant, especially in reduced and/or nil builder laundry formulations. There also remains a need for sulfonated/carboxylated polymers that are hydrophobically modified, inexpensive and yet provide good anti-spotting and anti- filming performance over a broad pH range. Soluble builders, such as conventional hydrotropes, may be added as coupling agents to liquid detergent compositions to improve performance but the use of conventional hydrotropes may be expensive. Another cost-effective approach involves the use of hydrophobically-modified, sulfonated/carboxylated polymers comprising a nonionic functionality that is aimed at permitting interaction with a structured surfactant, thereby giving a stable, concentrated, low viscosity, built, liquid surface-treating composition. Hydrophobically modified, sulfonated/carboxylated polymers outperform conventional hydrotropes by providing an improved stability over a wide range of pH (e.g. both high and low pH formulations). In fact, these hydrophobically-modified, sulfonated/carboxylated polymers offer more flexibility in formulating effective surface-treating compositions than conventional polymers since they may also comprise any suitable level of sulfonate and/or carboxylic acid functionality.

Sulfonated/carboxylated Polymer with Low Sulfonate Functionality fSMPLSF) The surface-treating compositions of the present invention may incorporate a cost- effective, water-soluble, sulfonated/carboxylated polymer with low sulfonate functionality, which is hereinafter referred to therein as an "SMPLSF." The at least one carboxylic acid functionality of a suitable SMPLSF may be present in any suitable amount. For example, the at least one carboxylic acid functionality may be present in any suitable amount less than or equal to about 0.01 mole %, or less than or equal to about 0.1 mole %, or less than or equal to about 1 mole %, or less than or equal to about 2 mole %, or less than or equal to about 5 mole %, or less than or equal to about 10 mole %, or less than or equal to about 20 mole %, or less than or equal to about 30 mole %, or less than or equal to about 40 mole %, or less than or equal to about 50 mole %, or less than or equal to about 55 mole %, or less than or equal to about 60 mole %, or less than or equal to about 65 mole %, or less than or equal to about 70 mole %, or less than or equal to about 75 mole %, or less than or equal to about 80 mole %, or less than or equal to about 85 mole %, or less than or equal to about 90 mole %, or less than or equal to about 95 mole %, or alternatively less than or equal to about 99.99 mole % of the total SMPLSF molar content. The optional one or more nonionic functionality of a suitable SMPLSF may be present, if at all, in any suitable amount to provide hydrophobicity. For example, when present, the one or more nonionic functionality may be greater than or equal to about 0.01 mole %, or greater than or equal to about 0.1 mole %, or greater than or equal to about 1 mole %, or greater than or equal to about 2 mole %, or greater than or equal to about 3 mole %, or greater than or equal to about 4 mole %, or greater than or equal to about 5 mole %, or greater than or equal to about 10 mole %, or greater than or equal to about 20 mole %, or greater than or equal to about 30 mole %, or greater than or equal to about 40 mole %, or greater than or equal to about 50 mole %, or greater than or equal to about 60 mole %, or greater than or equal to about 70 mole %, or greater than or equal to about 80 mole %, or greater than or equal to about 90 mole %, or greater than or equal to about 95 mole %, or alternatively greater than or equal to about 99.98 mole % of the total SMPLSF molar content. The at least one sulfonate functionality of a suitable SMPLSF may be present in any suitable amount less than 4 mole %. For example, the sulfonate functionality may be present at a level less than or equal to about 3.5 mole %, or less than or equal to about 3 mole %, or less than or equal to about 2.5 mole %, or less than or equal to about 2 mole %, or less than or equal to about 1.5 mole %, or less than or equal to about 1 mole %, or less than or equal to about 0.5 mole %, or equal to about 0.1 mole %, or alternatively less than or equal to about 0.01 mole % of the total SMPLSF molar content. In one non-limiting embodiment, a suitable SMPLSF may comprise: (a) from about 0.01 mole % to less than 4 mole % of at least one sulfonate functionality; and (b) from about 99.99 mole % to about 96 mole % of a carboxylic acid functionality. In another non-limiting embodiment, this SMPLSF may be free of an ester and/or an amide functionality. In another non-limiting embodiment, a suitable SMPLSF may comprise: (a) from about 0.01 mole % to about 95.99 mole % of at least one nonionic functionality; (b) from about 0.01 mole % to less than 4 mole % of at least one sulfonate functionality; and (c) from about 99.98 mole % to about 0.01 mole % of a carboxylic acid functionality. In another non-limiting embodiment, this SMPLSF may comprise an aromatic monomer, such as styrene. In another non-limiting embodiment, the at least one carboxylic acid functionality can comprise one or more of the following: acrylic acid, maleic acid, itaconic acid, methacrylic acid, or ethoxylate esters of acrylic acids. In another non-limiting embodiment, the sulfonate functionality can comprise one or more of the following: sodium (meth) allyl sulfonate, vinyl sulfonate, sodium phenyl (meth) allyl ether sulfonate, or 2-acrylamido-methyl propane sulfonic acid. In another non-limiting embodiment, the optional one or more nonionic functionality can comprise one or more of the following: methyl (meth) acrylate, ethyl (meth) acrylate, t-butyl (meth) acrylate, methyl (meth) acrylamide, ethyl (meth) acrylamide, t-butyl (meth) acrylamide, styrene, or ct-methyl styrene. In another non-limiting embodiment, a surface-treating composition may comprise an SMPLSF comprising styrene, having a molecular weight of less than or equal to about 100,000 Da. Stability In one non-limiting embodiment, the SMPLSF may be chemically stable in the surface-treating composition described herein in the presence of bleach and/or high pH. It is believed that stability of the SMPLSF is improved when an effective amount of one or more nonionic functionality is present, especially when the SMPLSF is free of an ester and/or amide functionality. This is not only useful for chlorine-containing and/or highly alkaline detergent products, but also in a chlorine-containing and/or highly alkaline wash water of a cleaning device (e.g. an automatic washing machine or dishwashing machine) where an ester and/or an amide functionality can be hydrolyzed and attacked in solution. Hydrophobically Modified Polymer (HMP) The surface-treating compositions of the present invention may also exhibit enhanced hard water anti-filming performance and improved product stability at a cheaper cost by incorporating a water-soluble, hydrophobically modified polymer comprising an effective amount of one or more nonionic monomers, at least one sulfonate-containing monomer, and at least one carboxylic acid-containing monomer, which is hereinafter referred to as an "HMP." The one or more nonionic functionality may be greater than or equal to about 0.01 mole %, or greater than or equal to about 0.1 mole %, or greater than or equal to about 1 mole %, or greater than or equal to about 2 mole %, or greater than or equal to about 3 mole %, or greater than or equal to about 4 mole %, or greater than or equal to about 5 mole %, or greater than or equal to about 10 mole %, or greater than or equal to about 20 mole %, or greater than or equal to about 30 mole %, or greater than or equal to about 40 mole %, or greater than or equal to about 50 mole %, or greater than or equal to about 60 mole %, or greater than or equal to about 70 mole %, or greater than or equal to about 80 mole %, or greater than or equal to about 90 mole %, or greater than or equal to about 95 mole %, or alternatively greater than or equal to about 99.98 mole % of the total HMP molar content. The at least one carboxylic acid functionality and/or at least one sulfonate functionality of a suitable HMP may be present in any suitable amount. For example, any of these functionalities may be present in any suitable amount less than or equal to about 0.01 mole %, or less than or equal to about 0.02 mole %, or less than or equal to about 0.1 mole %, or less than or equal to about 1 mole %, or less than or equal to about 2 mole %, or less than or equal to about 5 mole %, or less than or equal to about 10 mole %, or less than or equal to about 20 mole %, or less than or equal to about 30 mole %, or less than or equal to about 40 mole %, or less than or equal to about 50 mole %, or less than or equal to about 55 mole %, or less than or equal to about 60 mole %, or less than or equal to about 65 mole %, or less than or equal to about 70 mole %, or less than or equal to about 75 mole %, or less than or equal to about 80 mole %, or less than or equal to about 85 mole %, or less than or equal to about 90 mole %, or less than or equal to about 95 mole %, or alternatively less than or equal to about 99.98 mole % of the total HMP molar content. For example, in one non-limiting embodiment a suitable HMP may comprise: (a) from about 0.01 mole % to about 99.98 mole % of one or more nonionic functionality; (b) from about 0.01 mole % to less than 99.98 mole % of at least one sulfonate functionality; and (c) from about 99.98 mole % to about 0.01 mole % of a carboxylic acid functionality. In another non-limiting embodiment, a suitable water-soluble hydrophobically modified polymer may comprise: (a) from about 0.01 mole % to about 49.99 mole % of one or more nonionic functionality; (b) from about 0.01 mole % to about 49.99 mole % of a sulfonate-containing monomer; and (c) from about 0.02 mole % to about 99.98 mole % a carboxylic acid-containing monomer, by mole percent of the polymer. The at least one nonionic functionality may be selected from the group consisting of methyl (meth) acrylate, ethyl (meth) acrylate, t-butyl (meth) acrylate, methyl (meth) acrylamide, ethyl (meth) acrylamide, t-butyl (meth) acrylamide, styrene, α-methyl styrene, and combinations thereof. In another non-limiting embodiment, the HMP may comprise one or more nonionic monomers that may be free of an ester and/or an amide functionality. A suitable example of one or more nonionic monomers that do not contain an ester and/or amide functionality includes, but is not limited to, an aromatic monomer (such as, styrene). pH Any suitable pH may be used herein. A suitable pH may be from about 1 to about 14, when measured at a 1% concentration in an aqueous solution unless otherwise noted. In certain non-limiting embodiments, the surface-treating composition may exhibit an alkaline pH in the range of from about 8 to about 14, or from about 9 to about 12.5, from about 9 to about 11.5, or alternatively from about 9 to about 10. These alkaline surface- treating compositions may comprise chlorine bleach. In certain other non-limiting embodiments, the surface-treating composition may exhibit an acidic pH in the range of from about 1 to about 6.5, or from about 1 to about 6, or from about 1 to about 5, or from about 1 to about 4, or from about 1 to about 3, or alternatively from about 1 to about 2. In the case of automatic washing detergent compositions (such as, dishwashing detergents and heavy-duty or laundry detergents), mildly- to highly-alkaline compositions may be effectively used. However, in the case of hard surface cleaners (such as, medium- duty detergents and light-duty liquid detergents) less alkaline compositions may be desirable, especially when mildness to skin is a concern. In certain rinse aid compositions, a lower pH range may tend to reduce incompatibility and negative interaction with existing commercial product residues left in the dispenser reservoir of the automatic dishwashing machine prior to use.

In one non-limiting embodiment, the surface-treating composition may comprise from 0% to about 99.99%, or from about 0.01% to about 95%, or from about 0.01% to about 90%, or from about 0.01% to about 80%, or from about 0.01% to about 70%, or from about 0.01% to about 60%, or from about 0.01% to about 50%, or from about 0.01% to about 40%, or from about 0.01% to about 30%, or from about 0.01% to about 20%, or from about 0.01% to about 10%, or from about 0.01% to about 5%, or from about 0.01% to about 4%, or from about 0.01% to about 3%, or from about 0.01% to about 2%, or from about 0.01% to about 1%, or from about 0.01% to about 0.5%, or alternatively from about 0.01% to about 0.1%, by weight of the composition, of a suitable adjunct ingredient. PRODUCT FORM The surface-treating composition can be provided in any suitable physical form. A suitable form may include, but is not limited to: solids; granules; powder; liquid; paste; cream; gel; liquigels, and combinations thereof. The surface-treating compositions used herein can comprise a unitized dose in one of the following forms: tablets, multi-phase tablets, gel pacs, capsules, multi-compartment capsules, water-soluble pouches, or multi- compartment pouches. The surface-treating composition can be dispensed from any suitable device. Suitable devices include, but are not limited to: wipe, hand mittens, boxes, baskets, bottles (e.g. pourable bottles, pump assisted bottles, squeeze bottles), multi-compartment bottles, jars, paste dispensers, and combinations thereof. In the case of additive or multi-component products contained in single- and/or multi-compartment pouches, capsules, or bottles, it is not required that the adjunct ingredients nor the surface-treating compositions be in the same physical form. In one non-limiting embodiment, the surface-treating composition can provide in a multi- compartment, water-soluble pouch comprising both a solid and a liquid or gel component in a unit dose form. The presence of different forms may allow for a controlled release (e.g. delayed, sustained, triggered or slow release) of the surface-treating composition during treatment of a surface (e.g. during one or more wash and/or rinse cycles in an automatic dishwashing machine). Water-soluble Pouch Many of the surface-treating compositions described herein may demonstrate improved compatibility with partially hydrolysed, water-soluble polyvinyl alcohol (PVA) pouch materials of known construction and type. This is particularly surprising given that many well-known polar/or hydrolysed bonding solvent materials (for example the organoamines) in themselves have low compatibility with PVA materials and present serious issues for product stability. METHOD OF USE / COMPOSITION OF MATTER Any suitable domestic, institutional, industrial, and/or commercial method of treating a surface may be used in herein. In the methods described herein, any suitable surface-treating composition may be used, alone or in combination with a composition of matter (such as the wash and/or rinse water), and/or as part of an article of manufacture comprising a kit having a composition comprising an effective amount of a suitable sulfonated/carboxylated polymer. Any suitable surface may be treated with the sulfonated/carboxylated polymer described herein. In one non-limiting embodiment, the method may comprise the step of contacting a surface with a surface-treating composition comprising the sulfonated/carboxylated polymer described herein. In another non-limiting embodiment, the method may comprise the step of contacting tableware, especially glass and plastic, in a cleaning device (e.g. an automatic dishwashing machine) with a composition of matter comprising a wash and/or rinse water having a concentration from about 1 ppm to about 10,000 ppm by concentration, of the above described surface-treating composition, as delivered to the tableware surface via the cleaning device. In other non-limiting embodiments, the method may comprise the step of contacting laundry with a composition of matter comprising a wash and/or rinse water having a concentration from about 1 ppm to about 10,000 ppm by concentration, of the above-described surface-treating composition, as delivered to the laundry surface via a cleaning device (e.g. an automatic washing machine). In other non-limiting embodiments, the method may comprise the step of contacting a car surface with a composition of matter comprising a wash and/or rinse water having a concentration from about 1 ppm to about 10,000 ppm by concentration, of the above-described surface-treating composition, as delivered to the car surface via a cleaning device (e.g. an automatic car wash or hand-held pressure washer). EXAMPLES EXAMPLE 1 A surface-treating composition of the present invention may incorporate any suitable sulfonated/carboxylated polymer described herein. To prepare a suitable sulfonated/carboxylated polymer comprising acrylic acid ('AA'), styrene, sodium methallylsulfonate ('SMS') and sodium phenylmethallylether ('SPME') in the mole ratio 89:10:0.57:0.43, an initial charge of 150 g deionized water, 120 g isopropyl alcohol, 3.2 grams SMS and 4.0 grams SPME was added to a 1 -liter glass reactor fitted with a lid and having inlet ports for an agitator, water cooled condenser and for the addition of monomer and initiator solutions. The reactor contents were heated to reflux (approximately 85 °C). At reflux, continuous additions of 226 g of acrylic acid and 36.1 g of styrene were added concurrently to the reactor with stirring over a period of 3 hours. During the same time period and for 30 additional minutes, an initiator solution of 13.3 grams sodium persulfate dissolved in 80 grams water was also added. At the end of the initiator addition, a 50% aqueous sodium hydroxide solution (251 g) along with 100 grams water was added. The alcohol co-solvent (approximately 200 grams) was removed from the polymer solution by azeotropic distillation. The surface-treating compositions described herein can be suitably prepared and packaged by any process chosen by the formulator, non-limiting examples of which are described in U.S. Pat.
