In the event of a conflict between a definition in the present disclosure and one in a cited reference, the present disclosure controls.
100081 " The compositions as provided herein are described and claimed with reference to their ingredients, as is usual in the art. As would be evident to one skilled in the art, the ingredients may in some instances react with one another, so that the true composition of the final formulation may not correspond exactly to the ingredients listed. Thus, it should be understood that the invention extends to the product of the combination of the listed ingredients.
[0009] In certain embodiments, the present invention is directed to a composition that is useful for the cleaning or disinfecting of hard surfaces such as those typically found in bathrooms and kitchens, especially enamel, glass, metal, hard plastic, tile, glass, porcelain or ceramic surfaces, such as bathtubs, sinks, countertops and toilets. Other hard surfaces for which the compositions of the present invention may be useful include, e.g., metals such as stainless steel, and natural or synthetic minerals such as granite.
1000101 In various embodiments, the compositions of the present invention may be useful for the removal of soils such as, for example, grease, lime scale, soap scum, feces, rust or other soils. In certain embodiments, a composition of the present invention is an aqueous solution comprised of an organic acid, together with a nonionic surfactant, a thickener and an anti-adhesion polymer.
1000111 In various embodiments, the invention is also directed to methods for removing stains, e.g., those resulting from lime scale, soap scum, grease, feces or rust, from a hard surface, comprising applying the composition to the hard surface, and rinsing the composition, e.g., with water, or wiping off the composition, e.g., with a sponge, towel, brush or other implement.
1000121 The compositions of the present invention comprise an organic acid.
In certain embodiments, one or more organic acids may be present. In certain embodiments the compositions may further comprise an inorganic acid. Organic acids that are useful for the present embodiments may include, for example, acetic acid, lactic acid, citric acid, levulinic acid, tartaric acid, formic acid, glycolic acid, adipic acid, succinic acid, glutaric acid, maleic acid, methane sulfonic acid, sulfamic acid and oxalic acid. Inorganic acids are optional for the present invention and may include, for example, sulfuric acid, nitric acid, hydrochloric acid or phosphoric acid.
1000131 In various embodiments, at least one organic acid is lactic acid in an amount of about 2 to about 6% of the composition. In certain embodiments, the compositions may comprise two or more organic acids, or a combination of organic and inorganic acids, for example, formic and oxalic acids in a weight ratio of about 2:1 to about 5:1, or lactic acid and phosphoric acid in a weight ratio of about 1:3 to about 3:1.
100014] In various embodiments, the compositions of the present invention are such that the total amount of acid present (including both organic and inorganic acids) is about 4 to about 7.5% of the composition, about 4.5 to about 7% of the composition, or about 4.75 to about 6.75% of the composition.
1000151 In various embodiments, the compositions of the present invention may further comprise a hydrophilic polymer that adsorbs to hard surfaces, i.e., an anti-adhesion polymer. As used herein, the term "anti-adhesion polymer" refers to a polymer that prevents the adhesion of soils to a hard surface, either by creating a physical barrier impeding soils sticking to the surface or allowing a better flowing of the soil from the surface. In certain embodiments, the anti-adhesion polymer may be an amphoteric polymer, and/or may be a hydrophilic polymer.
1000161 In certain embodiments, the anti-adhesion polymer may comprise:a polybetaine. For example, useful polymers that may be included in the compositions of the present invention are those polymers available under the trade-marks "Mirapol Surf S-500" or "Mirapol Surf-S 110" from Rhodia, Inc.
(Tennessee, USA), and may be further described in U.S. Patent Application Publication No. 2006/0217286 to Geoffrey et al. Other useful polymers include, for example, a polymeric quaternary ammonium salt consisting of acrylamide and TM
dimethyl dialkyl ammonium chloride monomers, also known as Polyquatemium-7 and available, for example, under the trade-mark "Merquat 550" from Nalco Company (Illinois, USA); or water-soluble polymers such as those available under the trade-mark "Sokalan" from BASF Company (New Jersey, USA).
100017] In certain embodiments, the anti-adhesion polymer may be a polyacrylate polymer. In certain embodiments, amphoteric polyamines have been found to be useful as anti-adhesion polymers, such as those available under the trade-mark ''Sokalan" and available from BASF (New Jersey, USA). These include, for example, "Sokalan HP 70," or polycarboxylates such as maleic acid/olefin copolymers such as those available under the trade-marks "Sokalan CP 9" from BASF
or "Acusol 460 NK (available from Rohm Az Haas (Pennsylvania, USA).
1000181 The compositions of the present invention comprise a nonionic surfactant. Examples of nonionic surfactants useful for the present invention include the alkoxylated alcohol nonionic surfactants, for example, primary aliphatic alcohol ethoxvlates, secondary aliphatic alcohol ethoxylates, alkylphenol ethoxylates and ethylene-oxide-propylene oxide condensates on primary alkanols, such a PLURAFACgm(BASF, New Jersey, USA) and condensates of ethylene oxide with sorbitan fatty acid esters such as the compositions available under the various =
62 30 1 ¨ 2 956 TWEENS trade-marks, available from ICI Surfactants (New Jersey, USA). The nonionic synthetic organic detergents generally are the condensation products of an organic aliphatic or alkyl aromatic hydrophobic compound and hydrophilic ethylene oxide groups. Practically any hydrophobic compound having a carboxy, hydroxy, amido, or amino group with a free hydrogen attached to the nitrogen can be condensed with ethylene oxide or with the polyhydration product thereof, polyethylene glycol, to form a water-soluble nonionic detergent. Further, the length of the polyethenoxy chain can be adjusted to achieve the desired balance between the hydrophobic and hydrophilic elements.
1000191 The nonionic detergent class includes the condensation products of a higher alcohol (e.g., an alkanol containing 8 to 18 carbon atoms in a straight or branched chain configuration) condensed with about 5 to about 30 moles of ethylene oxide, for example, lauryl or myristyl alcohol condensed with about 16 moles of ethylene oxide (EO), tridecanol condensed with about 6 moles of E0, myristyl alcohol Condensed with about 10 moles of EO per mole of myristyl alcohol, the condensation product of E0 with a cut of coconut fatty alcohol containing a mixture of fatty alcohols with alkyl chains varying from 10 to 14 carbon atoms in length and wherein the condensate contains either about 6 moles of EO per mole of total alcohol or about 9 moles of EO per mole of alcohol and tallow alcohol ethoxylates containing 6 E0 to 11 E0 per mole of alcohol.
TM
1000201 In certain embodiments, the nonionic surfactants are the Neodol ethoxylates (available from Shell Co., USA), which are higher aliphatic, primary alcohol containing 9 to15 carbon atoms, such as C0-C11 alkanol condensed with 2.5 to 10 moles of ethylene oxide (NEODOL 91-2.5 or -5 or -6 or -8), Cu-C13 alkanol = condensed with 6.5 moles ethylene oxide (Neodol 23-6.5), C12-C15 alkanol condensed with 12 moles ethylene oxide (Neodol 25-12), C14-Cis alkanol condensed with 13 moles ethylene oxide (Neodol 45-13), and the like. In certain embodiments, the nonionic surfactant component is a mixture of Neodol 91-8 and Neodol 91-2.5 in the range of about 7:1 to about 3:1 weight ratio.
1000211 In certain embodiments, the nonionic system comprises the mixture of a nonionic surfactant formed from a C9-Cii alkanol condensed with 2 to 3.5 moles of =
ethylene oxide (C9-Cu alcohol EO 2 to 3.5:1) with a nonionic surfactant formed from a C9-Cil alkanol condensed with 7 to 9 moles of ethylene oxide (C9-Cit alcohol to 9:1), wherein the weight ratio of the C9-Cii alcohol EO 7 to 9:1 to the C9-Cii alcohol EO 2 to 3.5:1 is, in various embodiments, about 8:1 to about 1:1, or about 7:1 to about 3:1.
1000221 Additional satisfactory water soluble alcohol ethylene oxide condensates are the condensation products of a secondary aliphatic alcohol containing 8 to 18 carbon atoms in a straight or branched chain configuration condensed with 5 to 30 moles of ethylene oxide. Examples of commercially available nonionic detergents of the foregoing type are C11TC15 secondary alkanol condensed with either 9 EO (available under the trade-mark "TERGITOL 15-S-9") or 12 EO
(available under the trade-mark "TERGITOL 15-S-12") marketed by Union Carbide (USA).
1000231 Other suitable nonionic detergents include the polyethylene oxide condensates of one mole of alkyl phenol containing 8 to 18 carbon atoms in a straight- or branched chain alkyl group with about 5 to about 30 moles of ethylene oxide. Specific examples of alkyl phenol ethoxylates include nonyl phenol condensed with about 9.5 moles of EO per mole of nonyl phenol, dinonyl phenol condensed with about 12 moles of EO per mole of phenol, dinonyl phenol condensed with about 15 moles of EO per mole of phenol and di-isoctylphenol condensed with about 15 moles of EO per mole of phenol. Commercially available nonionic surfactants of this type include those available under the trade-mark "IGEPAL CO-630" (nonyl phenol ethoxylate) marketed by GAF Corporation (USA).
1000241 Also among the satisfactory nonionic detergents are the water-soluble condensation products of a C8-C20 alkanol with a heteric mixture of ethylene oxide and propylene oxide wherein the weight ratio of ethylene oxide to propylene oxide is about 2.5:1 to about 4:1, preferably about 2.8:1 to about 3.3:1, with the total of the ethylene oxide and propylene oxide (including the terminal ethanol or propanol group) being 60-85%, preferably 70-80%, by weight. Such detergents are commercially available from BASF-Wyandotte and a particularly preferred detergent is a C10-C16 alkanol condensate with ethylene oxide and propylene oxide, the weight ratio of ethylene oxide to propylene oxide being 3:1 and the total alkoxy content being about 75% by weight.
[00025] Condensates of 2 to 30 moles of ethylene oxide with sorbitan mono-and tri-C10-C20 alkanoic acid esters having a hydrophilic-lipophilic balance (HLB) of about 8 to about 15 also may be employed as the nonionic detergent ingredient in the described composition. These surfactants are known and are available from Imperial Chemical Industries (New Jersey, USA) under the TWEEN trade name.
Suitable surfactants include polyoxyethylene (4) sorbitan monolaurate, polyoxyethylene (4) sorbitan monostearate, polyoxyethylene (20) sorbitan trioleate and polyoxyethylene (20) sorbitan tristearate.
[00026] Other suitable water-soluble nonionic detergents are marketed under the trade name PLURONICS (available from BASF, New Jersey, USA). The compounds are formed by condensing ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol. The molecular weight of the hydrophobic portion of the molecule is of the order of 950 to 4000 and preferably 200 to 2,500. The addition of polyoxyethylene radicals to the hydrophobic portion tends to increase the solubility of the molecule as a whole so as to make the surfactant water-soluble. The molecular weight of the block polymers varies from about 1,000 to about 15,000 and the polyethylene oxide content may comprise about 20% to about 80% by weight.

62 30 1 ¨ 2 956 TWEENS trade-marks, available from ICI Surfactants (New Jersey, USA). The nonionic synthetic organic detergents generally are the condensation products of an organic aliphatic or alkyl aromatic hydrophobic compound and hydrophilic ethylene oxide groups. Practically any hydrophobic compound having a carboxy, hydroxy, amido, or amino group with a free hydrogen attached to the nitrogen can be condensed with ethylene oxide or with the polyhydration product thereof, polyethylene glycol, to form a water-soluble nonionic detergent. Further, the length of the polyethenoxy chain can be adjusted to achieve the desired balance between the hydrophobic and hydrophilic elements.
1000191 The nonionic detergent class includes the condensation products of a higher alcohol (e.g., an alkanol containing 8 to 18 carbon atoms in a straight or branched chain configuration) condensed with about 5 to about 30 moles of ethylene oxide, for example, lauryl or myristyl alcohol condensed with about 16 moles of ethylene oxide (EO), tridecanol condensed with about 6 moles of E0, myristyl alcohol Condensed with about 10 moles of EO per mole of myristyl alcohol, the condensation product of E0 with a cut of coconut fatty alcohol containing a mixture of fatty alcohols with alkyl chains varying from 10 to 14 carbon atoms in length and wherein the condensate contains either about 6 moles of EO per mole of total alcohol or about 9 moles of EO per mole of alcohol and tallow alcohol ethoxylates containing 6 E0 to 11 E0 per mole of alcohol.

1000201 In certain embodiments, the nonionic surfactants are the Neodol ethoxylates (available from Shell Co., USA), which are higher aliphatic, primary alcohol containing 9 to15 carbon atoms, such as C0-C11 alkanol condensed with 2.5 to 10 moles of ethylene oxide (NEODOL 91-2.5 or -5 or -6 or -8), Cu-C13 alkanol = condensed with 6.5 moles ethylene oxide (Neodol 23-6.5), C12-C15 alkanol condensed with 12 moles ethylene oxide (Neodol 25-12), C14-Cis alkanol condensed with 13 moles ethylene oxide (Neodol 45-13), and the like. In certain embodiments, the nonionic surfactant component is a mixture of Neodol 91-8 and Neodol 91-2.5 in the range of about 7:1 to about 3:1 weight ratio.
1000211 In certain embodiments, the nonionic system comprises the mixture of a nonionic surfactant formed from a C9-Cii alkanol condensed with 2 to 3.5 moles of =
ethylene oxide (C9-Cu alcohol EO 2 to 3.5:1) with a nonionic surfactant formed from a C9-Cil alkanol condensed with 7 to 9 moles of ethylene oxide (C9-Cit alcohol to 9:1), wherein the weight ratio of the C9-Cii alcohol EO 7 to 9:1 to the C9-Cii alcohol EO 2 to 3.5:1 is, in various embodiments, about 8:1 to about 1:1, or about 7:1 to about 3:1.
1000221 Additional satisfactory water soluble alcohol ethylene oxide condensates are the condensation products of a secondary aliphatic alcohol containing 8 to 18 carbon atoms in a straight or branched chain configuration condensed with 5 to 30 moles of ethylene oxide. Examples of commercially available nonionic detergents of the foregoing type are C11TC15 secondary alkanol condensed with either 9 EO (available under the trade-mark "TERGITOL 15-S-9") or 12 EO
(available under the trade-mark "TERGITOL 15-S-12") marketed by Union Carbide (USA).
1000231 Other suitable nonionic detergents include the polyethylene oxide condensates of one mole of alkyl phenol containing 8 to 18 carbon atoms in a straight- or branched chain alkyl group with about 5 to about 30 moles of ethylene oxide. Specific examples of alkyl phenol ethoxylates include nonyl phenol condensed with about 9.5 moles of EO per mole of nonyl phenol, dinonyl phenol condensed with about 12 moles of EO per mole of phenol, dinonyl phenol condensed with about 15 moles of EO per mole of phenol and di-isoctylphenol condensed with about 15 moles of EO per mole of phenol. Commercially available nonionic surfactants of this type include those available under the trade-mark "IGEPAL CO-630" (nonyl phenol ethoxylate) marketed by GAF Corporation (USA).

Such detergents are commercially available from BASF-Wyandotte and a particularly preferred detergent is a C10-C16 alkanol condensate with ethylene oxide and propylene oxide, the weight ratio of ethylene oxide to propylene oxide being 3:1 and the total alkoxy content being about 75% by weight.
[00025] Condensates of 2 to 30 moles of ethylene oxide with sorbitan mono-and tri-C10-C20 alkanoic acid esters having a hydrophilic-lipophilic balance (HLB) of about 8 to about 15 also may be employed as the nonionic detergent ingredient in the described composition. These surfactants are known and are available from Imperial Chemical Industries (New Jersey, USA) under the TWEEN trade name.
Suitable surfactants include polyoxyethylene (4) sorbitan monolaurate, polyoxyethylene (4) sorbitan monostearate, polyoxyethylene (20) sorbitan trioleate and polyoxyethylene (20) sorbitan tristearate.
[00026] Other suitable water-soluble nonionic detergents are marketed under the trade name PLURONICS (available from BASF, New Jersey, USA). The compounds are formed by condensing ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol. The molecular weight of the hydrophobic portion of the molecule is of the order of 950 to 4000 and preferably 200 to 2,500. The addition of polyoxyethylene radicals to the hydrophobic portion tends to increase the solubility of the molecule as a whole so as to make the surfactant water-soluble. The molecular weight of the block polymers varies from about 1,000 to about 15,000 and the polyethylene oxide content may comprise about 20% to about 80% by weight. Preferably, these surfactants will be in liquid form and satisfactory surfactants are available as grades L 62 and L
64. In certain embodiments, useful nonionics include alkyl polyglucosides.
