Abstract: Disclosed are liquid detergent compositions containing from about 5% to about 40% of an alkyl sulfate or alkyl ethoxylated sulfate surfactant, or mixture thereof, and water-insoluble, amine-organic anion ion-pair conditioning particles in a liquid base. The alkyl sulfate, alkyl ethoxylated sulfate, or mixture thereof, stabilizes the conditioning particles for improved shelf-­ life.

Description: TECHNICAL FIELD This invention relates to liquid detergent compositions containing an alkyl sulfate/alkyl ethoxylated sulfate surfactant component, or mixtures thereof, and an amine-organic anion ion-pair complex conditioning agent. BACKGROUND OF THE INVENTION Numerous attempts have been made to formulate laundry detergent compositions which provide the good cleaning performance expected of them and which also have good through-the-wash fabric conditioning benefits, such as softening and anti-static properties. Attempts have been made to incorporate cationic conditioners in anionic surfactant-based built detergent compositions employing various means of overcoming the natural antagonism between the anionic and cationic surfactants. For instance, U.S. Patent 3,936,537, Baskerville et al., issued February 3, 1976, discloses detergent compositions comprising organic surfactant, builders, and, in particulate form (10 to 500 micrometers), a quaternary ammonium softener combined with a poorly water-soluble dispersion inhibitor which inhibits premature dispersion of the cationic in the wash liquor. Even in these compositions some compromise between cleaning and softening effectiveness has to be accepted. Another approach to provide detergent compositions with softening ability has been to employ nonionic surfactants (instead of anionic surfactants) with cationic softeners. Compositions of this type have been described in, for example, German Patent 1,220,956, assigned to Henkel, issued April 4, 1964; and in U.S. Patent 3,607,763, Salmen et al., issued September 21, 1971. However, the detergency benefits of nonionic surfactants are inferior to those of anionic surfactants, especially relative to alkyl sulfates and alkyl ethoxylated sulfates, which provide excellent cleaning performance in liquid detergent compositions. In European Patent Application 268 324, filed November 6, 1987, amine-anionic compound ion-pair complex particles having an average particle diameter of from 10 micrometers to 300 micrometers were disclosed. These particles provide excellent through-the-wash conditioning without significantly impairing cleaning performance. European Patent Application 268 324 further discloses that ion-pair particles which are made from lower alkyl chain length linear alkyl benzene sulfonates impart improved processing characteristics and also improved chemical stability in liquid detergents to provide longer shelf-life to the conditioning agent particles. Even further improvements in the processing characteristics and chemical stability of amine-organic anion ion-pair complex particles are obtained by incorporating certain levels of amine-inorganic ion-pair complexes into the particles. Still, further improvements in stability of the ion-pair particles in liquid detergent compositions that are aggressive toward ion-pair conditioning particles, such as compositions containing high levels of anionic and nonionic surfactants, fatty builders, and polar solvents, are desirable. Also, higher levels of cleaning performance in conjunction with excellent through-the-wash fabric conditioning are desirable. European Patent Application 294 894, filed on 6th June 1988, discloses the use of ion-pair/wax composites as fibre and fabric conditioning agents. Both Applications 268 324 and 298 894 form a part of the state of the art in accordance with Article 54(3) EPC. It is an object of this invention to provide a liquid detergent composition having excellent cleaning performance and excellent through-the-wash fabric conditioning performance. More specifically, it is an object of this invention to provide a liquid detergent composition as described above wherein the fabric conditioning agent therein comprises amine-organic anion ion-pair complex particles, and wherein the conditioning particles have improved stability, and therefore extended shelf-life, in detergent compositions with exceptional cleaning performance. SUMMARY OF THE INVENTION The present invention relates to liquid detergent compositions comprising: 1) a liquid base; 2) from 7.0% to 40% of a surfactant component selected from alkyl sulfates and alkyl ethoxylated sulfates, and mixtures thereof; and 3) from 0.1% to 20% of water-insoluble ion-pair conditioning particles having an average diameter of from 10 to 500 micrometers and containing less than 1% of a nonsilicone wax, said particles comprising an amine-organic anion ion-pair complex having the formula: wherein each R₁ and R₂ can independently be C₁₂ to C₂₀ alkyl or alkenyl, and R₃ is H or CH₃, and A is an organic anion selected from the group consisting of alkyl sulfonates, aryl sulfonates, alkylaryl sulfonates, alkyl sulfates, dialkyl sulfosuccinates, alkyl oxybenzene sulfonates, acyl isethionates, acylalkyl taurates, alkyl ethoxylated sulfates, olefin sulfonates, and mixtures of such anions. The detergent composition has a pH of from 5 to 10. Optionally, the ion-pair conditioning particles also contain from 5% to 95% of an amine-inorganic anion ion-pair complex having the formula: wherein each R₁ and R₂ can independently be C₁₂ to C₂₀ alkyl or alkenyl, each R₃ is H or CH₃, and x corresponds to the molar ratio of the amine to the inorganic anion and the valence of the inorganic anion, x being an integer between 1 and 3, inclusive. B is an inorganic anion selected from the group consisting of sulfate (SO₄⁻²), hydrogen sulfate (HSO₄⁻¹), nitrate (NO₃⁻), phosphate (PO₄⁻³), hydrogen phosphate (HPO₄⁻²), and dihydrogen phosphate (H₂PO₄⁻¹), and mixtures thereof, preferably sulfate or hydrogen sulfate. Inclusion of the optional amine-inorganic anion ion-pair complex in the conditioning particles can improve processing characteristics of the particles. The liquid compositions can additionally contain other surfactants, detergent builders, chelating agents, enzymes, soil release agents, anti-redeposition agents, and other detergent components useful for fabric cleaning or conditioning applications. It has been observed that common liquid detergent components, including certain polar solvents, surfactants, and builders, can detrimentally affect stability of the amine-organic anion ion-pair conditioning particles, set forth above. It has now surprisingly been discovered that high levels of alkyl sulfate and alkyl ethoxylated sulfate added to the liquid detergent composition promotes stability of the ion-pair conditioning particles. DETAILED DESCRIPTION OF THE INVENTION As used herein, the term "liquid detergent composition" shall refer to compositions containing a liquid base, a surfactant component selected from alkyl sulfates and alkyl ethoxylated sulfates, and the ion-pair conditioning particles . As used herein, the term "alkyl sulfate" surfactant shall specifically refer to non-ethoxylated alkyl sulfate surfactants. The liquid detergent composition may optionally contain other surfactants and conditioning agents, and may also contain builders, other cleaning ingredients, or other optional ingredients such as chelating agents, enzymes, soil release agents, and anti-redeposition agents. All percentages set forth below to describe the amount of any particular detergent component in the liquid detergent composition are defined as a weight percentage of the total liquid detergent composition, unless otherwise specifically indicated. Conditioning Particles The ion-pair conditioning particles comprise water-insoluble particles comprised of certain amine-organic anion ion-pair complexes and, optionally, certain amine-inorganic anion ion-pair complexes. The amine-organic anion ion-pair complexes can be represented by the following formula: wherein each R₁ and R₂ can independently be C₁₂ to C₂₀ alkyl or alkenyl, and each R₃ is H or CH₃. A represents an organic anion and includes a variety of anions derived from anionic surfactants, as well as related shorter alkyl or alkenyl chain compounds which need not exhibit surface activity. A is selected from the group consisting of alkyl sulfonates, aryl sulfonates, alkylaryl sulfonates, alkyl sulfates, dialkyl sulfosuccinates, alkyl oxybenzene sulfonates, acyl isethionates, acylalkyl taurates, alkyl ethoxylated sulfates, and olefin sulfonates, and mixtures of such anions. As used herein the term alkyl sulfonate shall include those alkyl compounds having a sulfonate moiety at a fixed or predetermined location along the carbon chain, as well as compounds having a sulfonate moiety at a random position along the carbon chain. The optionally incorporated amine-inorganic anion ion-pair complexes can be represented by the following formula: wherein each R₁ and R₂ can independently be C₁₂ to C₂₀ alkyl or alkenyl, each R₃ is H or CH₃, and x corresponds to the molar ratio of the amine to the inorganic anion and the valence of the inorganic anion, x being an integer between 1 and 3, inclusive. B is an inorganic anion selected from the group consisting of sulfate (SO₄⁻²), hydrogen sulfate (HSO₄⁻¹), nitrate (NO₃⁻), phosphate (PO₄⁻³), hydrogen phosphate (HPO₄⁻²), and dihydrogen phosphate (H₂PO₄⁻¹), and mixtures thereof, preferably sulfate or hydrogen sulfate. It has been found that in order for the conditioning particles of the present invention to impart their fabric care benefits through the wash they should have an average particle diameter of from 10 to 500 micrometers. Preferably the particles have an average diameter of less than 350 micrometers, and more preferably less than 200 micrometers, and most preferably less than 150 micrometers. Also preferably, the particles have an average diameter of greater than 40 micrometers, and more preferably greater than 50 micrometers. The term "average particle diameter" represents the mean particle size diameter of the actual particles of a given material. The mean is calculated on a weight percent basis. The mean is determined by conventional analytical techniques such as, for example, laser light diffraction or microscopic determination utilizing a scanning electron microscope. Preferably, greater than 50% by weight, more preferably greater than 70% by weight, and most preferably greater than 90% by weight, of the particles have actual diameters which are less than 500 micrometers, preferably less than 350 micrometers, and more preferably less than 200 micrometers. Also preferably, greater than 50% by weight, more preferably greater than 70% by weight, and most preferably greater than 90% by weight, of the particles have actual diameters which are greater than 10 micrometers, preferably greater than 40 microns, and more preferably greater than 50 micrometers. The complexing of an amine with the organic anion and, optionally, with the inorganic anion results in ion-pair entities which are chemically distinct from the respective starting materials. Such factors as the type of amine and the type of organic anion or inorganic anion employed, the ratio of the amine to the organic anion and inorganic anion, in addition to the ratio of amine-organic anion ion-pair complex to amine-inorganic anion ion-pair complex can affect the physical properties of the resulting complexes, including the thermal phase transition points which affects whether the complex has a gelatinous (soft) or solidified (hard) character at a particular temperature. These factors as discussed in more detail below. The conditioning particles which contain the optional ion-pair complex of Formula (2) preferably contain from 5% to 95%, by weight of the particles, of the amine-organic anion ion-pair complex of Formula (1) and from 95% to 5% of the amine-inorganic anion ion-pair complex of Formula (2), more preferably between 40% and 90% of the Formula (1) complex and between 60% and 10% of the Formula (2) complex, even more preferably between 50% to 80% of the Formula (1) complex and 50% to 20% of the Formula (2) complex, and for highly preferred conditioning particles wherein the Formula (1) complex anion component is a C₃ linear alkyl benzene sulfonate (cumene sulfonate), most preferably 70% of the Formula (1) complex and 30% of the Formula (2) complex. The ratio of Formula (1) complex to Formula (2) complex can affect whether particles containing these ion-pair complexes have a gelatinous (soft) or solidified (hard) character at a particular temperature. By including proportionally more of the ion-pair complex of Formula (2), the particles tend to become more solidified (hard), and therefore easier to form into particles by prilling or mechanical processing. By including proportionately more of the fabric care active ion-pair complex of Formula (1) in the comelt mixtures, particles made from such comelt mixtures tend to have higher fabric care conditioning performance. Thus, the optimal fabric care conditioning agent formulations will involve a balancing of these factors, and will not necessarily be the same for all applications. Such balancing, however, can be performed by one of ordinary skill in the art without undue experimentation. Starting amines for the Formula (1) ion-pair complex are of the formula: wherein each R₁ and R₂ are independently C₁₂ to C₂₀ alkyl or alkenyl, preferably C₁₆ to C₂₀ alkyl or alkenyl, and most preferably C₁₆ to C₂₀ alkyl, and R₃ is H or CH₃. Suitable non-limiting examples of starting amines include ditallow amine, ditallow methyl amine, dipalmityl amine, dipalmityl methyl amine, distearyl amine, distearyl methyl amine, diarachidyl amine, diarachidyl methyl amine, palmityl stearyl amine, palmityl stearyl methyl amine, palmityl arachidyl amine, palmityl arachidyl methyl amine, stearyl arachidyl amine, stearyl arachidyl methyl amine, tallow palmityl amine, tallow palmityl methyl amine, tallow stearyl amine, tallow stearyl methyl amine, tallow arachidyl amine, and tallow arachidyl methyl amine. Most preferred are ditallow amine, distearyl amine, ditallow methyl amine and distearyl methyl amine. The organic anions (A) useful in the ion-pair complex of the present invention are the alkyl sulfonates, aryl sulfonates, alkylaryl sulfonates, alkyl sulfates, alkyl ethoxylated sulfates, dialkyl sulfosuccinates, alkyl oxybenzene sulfonates, acyl isethionates, acylalkyl taurates, olefin sulfonates, and mixtures thereof. Preferred organic anions are the C₁-C₂₀ alkyl sulfonates, C₁-C₂₀ alkylaryl sulfonates, C₁-C₂₀ alkyl sulfates, C₁-C₂₀ alkyl ethoxylated sulfates, aryl sulfonates, and dialkyl sulfosuccinates. More preferred are the C₁-C₂₀ alkyl ethoxylated sulfates, C₁-C₂₀ alkylaryl sulfonates, aryl sulfonates, and dialkyl sulfosuccinates. Even more preferred are C₁-C₂₀ alkylaryl sulfonates and aryl sulfonates and especially preferred are benzene sulfonates (as used herein, benzene sulfonates contain no hydrocarbon chain attached directly to the benzene ring) and C₁-C₁₃ alkylaryl sulfonates, including the C₁-C₁₃ linear alkyl benzene sulfonates (LAS). The benzene sulfonate moiety of LAS can be positioned at any carbon atom of the alkyl chain, and is commonly at the second carbon atom for alkyl chains containing three or more carbon atoms. Most preferred organic anions are benzene sulfonates and C₁-C₅ linear alkylbenzene sulfonates (LAS), particularly C₁-C₃ LAS. The anions listed above can generally be obtained in their acid or soluble salt forms from commercial chemical sources such as Aldrich Chemical Co., Inc. in Milwaukee, Wisconsin, Vista Chemical Co. in Ponca, Oklahoma, and Reutgers-Nease Chemical Co. in State College, Pennsylvania. Acids of the anions are preferred. The amines can be obtained from Sherex Chemical Corp., in Dublin, Ohio. Preferred are complexes formed from the combination of ditallow amine complexed with an aryl sulfonate or C₁-C₂₀ alkylaryl sulfonate, ditallow methyl amine complexed with an aryl sulfonate or a C₁-C₂₀ alkylaryl sulfonate, distearyl amine complexed with an aryl sulfonate or a C₁-C₂₀ alkylaryl sulfonate and distearyl methyl amine complexed with an aryl sulfonate or a C₁₋₂₀ alkylaryl sulfonate. Even more preferred are those complexes formed from ditallow amine, ditallow methyl amine, distearyl amine or distearyl methyl amine complexed with a benzene sulfonate of a C₁-C₁₃ linear alkylbenzene sulfonate (LAS). Even more preferred are complexes formed from ditallow amine, ditallow methyl amine, distearyl amine or distearyl methyl amine complexed with a benzene sulfonate or a C₁-C₅ linear alkylbenzene sulfonate. Most preferred are complexes formed from ditallow amine, ditallow methyl amine, distearyl amine or distearyl methyl amine complexed with C₁-C₃ LAS. Starting amines for the optional Formula (2) ion-pair complexes are of the formula: wherein each R₁ and R₂ are independently C₁₂ to C₂₀ alkyl or alkenyl, preferably C₁₆ to C₂₀ alkyl or alkenyl, and most preferably C₁₆ to C₂₀ alkyl, and each R₃ is H or CH₃. Suitable non-limiting examples of starting amines for the Formula (2) complexes include ditallow amine, ditallow methyl amine, dipalmityl amine, dipalmityl methyl amine, distearyl amine, distearyl methyl amine, diarachidyl amine, diarachidyl methyl amine, palmityl stearyl amine, palmityl stearyl methyl amine, palmityl arachidyl amine, palmityl arachidyl methyl amine, stearyl arachidyl amine, stearyl arachidyl methyl amine, tallow palmityl amine, tallow palmityl methyl amine, tallow stearyl amine, tallow stearyl methyl amine, tallow arachidyl amine, and tallow arachidyl methyl amine. The inorganic anion component of the amine-inorganic anion ion-pair complex can be obtained from inorganic acids, including acids having monovalent, divalent, and trivalent anions such as nitric acid, sulfuric acid, and phosphorous acid. Especially preferred is sulfuric acid. These acids are commonly available from chemical supply companies, including Aldrich Chemical Company, Inc., Milwaukee, Wisconsin, and Sigma Chemical Company, St. Louis, Missouri. The fabric care agent of the present invention can comprise particles which contain both the amine-organic anion ion-pair complex of Formula 1 and the amine-inorganic anion ion-pair complex of Formula 2. These two types of ion-pair complexes are physically combined in a way such that particles can be formed which comprise said combination of ion-pair complexes. This can be accomplished by separately forming each type of ion-pair complex, and then physically combining them by mixing the two molten ion-pair complexes together. Another method for providing a mixture of the two types of ion-pair complexes is to form said complexes conjointly, for example by preparing a melt containing the organic anion component, A, the inorganic anion component, B, and a sufficient amount of the amine components to form the desired levels of each type of ion-pair complex. The amine and organic anion are combined in a molar ratio of amine to anionic compound ranging from 10:1 to 1:2, preferably from 5:1 to 1:2, more preferably from 2:1 to 1:2 and most preferably about 1:1. For the preferred amine-organic anion/amine-inorganic anion conditioning particles wherein the organic anion is C₁-C₃LAS and the inorganic anion is the divalent sulfate anion, the amine and inorganic anion are combined in a molar ratio ranging from 10:1 to 1:2, preferably from 5:1 to 1:2, more preferably from 3:1 to 1:1, and most preferably about 2:1. The amine quantity indicated in the above ratios is based upon separate preparation of the Formula 1 and Formula 2 ion-pair complexes. Accordingly, when the Formula 1 and Formula 2 ion-pair complexes are formed conjointly, the molar ratio of amine to organic anion to inorganic anion will depend on the preferred ratio of the Formula (1) and Formula (2) complexes. For example, for the highly preferred ditallow amine-C₃LAS/ditallow amine-sulfate comelt utilized in a 70:30 weight ratio of ditallow amine-C₃LAS to ditallow amine-sulfate, the molar ratios of the ditallow amine C₃LAS, and sulfate in the starting materials will be about 5.7:3.7:1.0. Another method of forming the conditioning particles is to heat the amine to a liquid state, add the desired amounts of this molten amine component to separate heated acidified aqueous solutions of the organic anion and the inorganic anion, and then extract the ion-pair complexes by using a solvent, such as chloroform. Alternatively, the molten amine can be added to a mixture of heated acidified aqueous solutions of the organic anion and inorganic anion, followed by solvent extraction. The desired particle sizes can be achieved by, for example, mechanically grinding the ion-pair complexes in blenders (e.g., an Oster® blender) or in large scale mills (e.g., a Wiley® Mill) to the desired particle size range. Preferably, the particles are formed by prilling in a conventional manner, such as by hydraulically forcing a comelt of the ion-pair complexes through a heated nozzle. Prior to passage through the nozzle, the comelt should be in a well-mixed condition, for example by continuously circulating the comelt through a loop at sufficient velocity to prevent settling. As an alternative to hydraulically forcing the comelt through the nozzle, air injection can be used to pass the comelt through the nozzle. Particle diameters within the preferred ranges can be obtained directly from the prilling apparatus or, when additional control over average particle is desired, such desired particle size can be obtained by conventional screening techniques. Comelts of complexes which are gelatinous (ie, soft) at room temperature can be mechanically ground to achieve the desired particle size after flash freezing by using, for example, liquid nitrogen. The particles can then be incorporated into a liquid delivery system, such as a detergent base or an aqueous base useful for forming an aqueous dispersion of the particles. Alternately, the comelt can be added to the liquid delivery system, such as a detergent base, and then be formed into particles by high shear mixing. The complexes can be characterized for the purposes of this invention by their thermal phase transition points. As used hereafter, the thermal phase transition (hereinafter alternately referred to as "transition point") shall mean the temperature at which the complex exhibits softening (solid to liquid crystal phase transition) or melting (solid to isotropic phase transition) whichever occurs first upon heating. The transition point temperatures can be determined by differential scanning colorimetry (DSC) and/or polarized light microscopy. The first transition point of solid particles made from the ion-pair complex or mixture of ion-pair complexes will preferably be between 10°C and 100°C, more preferably between 30°C and 100°C, and most preferably between 35°C and 80°C. With respect to the amine-organic anion ion-pair complexes, generally shorter alkyl or alkenyl chain length anions will form complexes with higher transition points than complexes that are identical except for having an anion with a longer chain length. Highly preferred ion-pairs are made with C₁-C₁₃ LAS or benzene sulfonate and generally have transition points in the range of 10°C-100°C. The amine-organic anion ion-pair complexes made with C₆-C₁₃ LAS generally have first transition points in the range of 15°C to 30°C and tend to be gelatinous (soft). The amine-organic anion ion-pair complexes made with C₁-C₅ LAS and benzene sulfonate (i.e., no alkyl chain) generally have first transition points in the range of 30°C to 100°C and tend to be more solidified (hard), and therefore tend to form comelted amine-organic anion ion-pair complexes or amine-organic anion/amine-inorganic anion ion-pair complex mixtures that are more susceptible to prilling. Preferred conditioning particles are made with organic anion components derived from C₁-C₃ LAS and have transition points, apart from the amine-inorganic anion ion-pair complex, in the range of 35°C to 100°C. Preferred amine-organic anion ion-pair complexes include those comprised of a ditallow amine, ditallow methyl amine, distearyl amine or distearyl methyl amine complexed with a C₁ to C₃ LAS in a 1:1 molar ratio. These complexes have transition points generally between 35°C and 100°C. The preferred amine-inorganic anion ion-pair complexes for use with the preferred amine-organic anion ion-pair complexes include ditallow amine, ditallow methyl amine, distearyl amine and distearyl methyl amine complexed with sulfate in a 2:1 molar ratio. The temperature ranges listed above are approximate in nature, and are not meant to exclude complexes outside of the listed ranges. Further, it should be understood that the particular amine of the ion-pair complex can affect the transition point. For example, for the same anionic compound, distearyl amines will form harder ion-pair complexes than ditallow amines, and ditallow amines will form harder ion-pair complexes than ditallow methyl amines. The ideal conditioning particle is sufficiently large so as to become entrapped in fabrics during washing, and has a transition point which is low enough that at least a substantial part of the particle, preferably the entire particle, will soften or melt at conventional automatic laundry dryer temperatures, but not so low that it will melt during the fabric wash or rinse stages. The ion-pair conditioning particles can be incorporated into detergent compositions or used in the presence of detergent compositions, with little, if any, detrimental effect on cleaning. These conditioning particles provide conditioning benefits across a variety of laundry conditions, including machine or hand washing followed by machine drying and also machine or hand washing followed by line drying. Additionally, these same conditioning agents can be used with a variety of surfactant systems. The conditioning particles are used herein at levels of 0.1% to 20.0%, preferably 0.1% to 10%, of the liquid detergent composition. Detergent composition components are described below. Liquid Base The liquid detergent compositions of the present invention have a liquid base component which functions as a carrier and diluent of the other detergent compositions. The liquid base is preferably water or other polar solvents, or mixtures thereof. Exemplary nonlimiting polar solvents, in addition to water, include low molecular weight primary and secondary monohydric alcohols such as methanol, ethanol, and isopropanol, and polyols containing from 2 to 6 carbon atoms and from 2 to 6 hydroxy groups such as propylene glycol, ethylene glycol, glycerine, and 1,3-propanediol. Typically, the liquid detergent composition will contain between 30% and 80% of the liquid base, and preferably will contain between 20% and 70% water. Alkyl Sulfate/Alkyl Ethoxylated Sulfate Surfactant Component The detergent compositions of the present invention have as an essential element alkyl sulfate/alkyl ethoxylated sulfate surfactant component. This surfactant component can comprise alkyl sulfate (i.e., nonethoxylated alkyl sulfate) and/or alkyl ethoxylated sulfate surfactants. These surfactants typically have from 10 to 20 carbon atoms in the alkyl or hydroxyalkyl group, and can have the formula RO(C₂H₄O) m SO₃M wherein R is a C₁₀-C₂₀ alkyl or hydroxyalkyl group having a C₁₀-C₂₀ alkyl component, preferably a C₁₂-C₁₆ alkyl or hydroxyalkyl, more preferably C₁₂-C₁₅ alkyl or hydroxyalkyl, M is from 0 (inclusive) to 4, and M is a cation which can be, for example, an alkali metal cation (e.g., sodium, potassium, lithium), ammonium or substituted-ammonium cation. Specific examples of substituted ammonium cations include methyl-, dimethyl-, and trimethyl-ammonium cations and quaternary ammonium cations such as tetramethyl-ammonium and dimethyl piperidinium cations and those derived from alkylamines such as ethylamine, diethylamine, triethylamine, mixtures thereof, and the like, said salt preferably being an olefin sulfonate salt having from 12 to 24 carbon atoms. For alkyl sulfates, m will be 0. For surfactant components containing alkyl ethoxylated sulfates, m will typically be between 0.5 and 4, preferably between 0.5 and 3. Examples of preferred surfactants in the surfactant component are C₁₂-C₁₆ nonethoxylated alkyl sulfate (C₁₂₋₁₆E(0) M ), C₁₂-C₁₆ alkyl polyethoxylate (1.0) sulfate (C₁₂₋₁₆E(1.0) M ), C₁₂-C₁₆ alkyl polyethoxylate (2.25) sulfate (C₁₂₋₁₆E(2.25) M ), C₁₂-C₁₆ alkyl polyethoxylate (3.0) sulfate (C₁₂₋₁₆E(3.0) M ), and C₁₂-C₁₆ alkyl polyethoxylate (4.0) sulfate (C₁₂₋₁₆E(4.0) M ), wherein M is selected from sodium and potassium. The alkyl sulfate/alkyl ethoxylated sulfate surfactant component can be prepared by sulfating a nonethoxylated straight or branched chain alcohol having an alkyl group containing from 10 to 18 carbon atoms, preferably from 12 to 16 carbon atoms, or by sulfating an ethoxylated alcohol having an alkyl group containing from 10 to 18 carbon atoms, preferably from 12 to 16 carbon atoms, or by sulfating a mixture of such nonethoxylated and ethoxylated alcohols. Nonethoxylated alcohols as described above are commonly available. The ethoxylated alcohols described above are preferably produced by first ethoxylating a nonethoxylated alcohol (described above) with an average of 0.5 to 4, preferably from 0.5 to 3, moles of ethylene oxide per mole of alcohol, by a conventional alkaline-catalyzed ethoxylation reaction. The alkyl sulfate and/or alkyl ethoxylated sulfate should, as a final step. be neutralized with an appropriate base. Typically, the surfactant component which contains alkyl ethoxylated sulfate will also contain some alkyl sulfate, due to incomplete ethoxylation of the alcohol. The products obtained will also typically have a mixture of alkyl or alkyl ethoxylate chain lengths. The alkyl sulfates and/or alkyl ethoxylated sulfates of the surfactant component are used as water soluble or dispersible salts, preferably sodium, potassium, ammonium, monoethanol ammonium, diethanol ammonium, triethanol ammonium, or magnesium salts, or mixtures thereof. A particularly preferred anionic surfactant is the sodium salt of the sulfated reaction product of a mixture of fatty alcohols containing from 14 to 15 carbon atoms with approximately 0.5 to approximately 3.0 moles of ethylene oxide. The liquid detergent compositions of this invention will contain at least 7.0% and no more than 40% of the surfactant component, preferably less than 25% of the surfactant component. The upper limit of 40% is merely a practical limit due in part to sudsing which is typically imparted by alkyl sulfate/alkyl ethoxylated sulfate surfactants upon agitation. Anti-sudsing agents discussed in more detail below, can be utilized to control sudsing, and will be desirable particularly when the surfactant component content is above 25%. Anti-Sudsing Agents Non-soap suds suppressors are preferred, although fatty acid such as hardened marine oil fatty acids (predominantly C₁₈ to C₂₀) can be used. Preferred suds suppressors comprise silicones. In particular there may be employed a particulate suds suppressor comprising silicone and silanated silica releasably enclosed in water soluble or dispersible substantially non-surface active detergent impermeable carrier. Suds suppressing agents of this sort are disclosed in British Patent 1,407,997. A suitable suds suppressing product comprises 7% silica/silicone (15% by weight silanated silica, 85% silicone, obtained from Dow Corning), 65% sodium tripolyphosphate, 25% tallow alcohol condensed with 25 molar proportions of ethylene oxide, and 3% moisture. The amount of silica/silicone suds suppressor employed depends upon the degree of suds suppression desired but it is often in the range from 0.01% to 0.5% by weight of the detergent composition. Other suds suppressors which may be used are water insoluble waxes, preferably microcrystalline, having melting point in the range from 35° to 125°C and saponification value less than 100, as described in British Patent 1,492,938. Yet other suitable suds suppressing systems are mixtures of hydrocarbon oil, a hydrocarbon wax and hydrophobic silica as described in published European Patent Application 0000216 and, especially, particulate suds suppressing compositions comprising such mixtures, combined with a nonionic ethoxylate having hydrophilic lipophilic balance in the range from 14-19 and a compatibilising agent capable of forming inclusion compounds, such as urea. These particulate suds suppressing compositions are described in European published Patent Application 0008830. Detergent Surfactant System The amount of total detergent surfactant (including the alkyl sulfate and/or alkyl ethoxylated sulfate surfactant) included in detergent compositions of the present invention can vary from 7% to 98% by weight of the composition, depending upon the particular surfactant(s) used and the effects desired. Preferably, the total detergent surfactant(s) comprises from 10% to 60% by weight of the composition. Combinations of anionic, cationic and nonionic surfactants, in addition to the anionic alkyl sulfates and alkyl ethoxylated sulfates discussed above as part of the essential surfactant component, can be used. Liquid detergent compositions preferably contain primarily anionic surfactants or combinations of anionic and nonionic surfactants. Preferred optional anionic surfactants for liquid detergent compositions include linear alkyl benzene sulfonates. Preferred nonionic surfactants include alkyl polyethoxylated alcohols. Other classes of surfactants, such as semi-polar, ampholytic, zwitterionic, or cationic surfactants can be used. Mixtures of these surfactants can also be used. A. Additional Anionic Detergent Surfactants Consistent with the art pertaining to detergent surfactants, liquid detergents typically incorporate stable acid forms of the surfactants. Optional anionic detergent surfactants suitable for use in the present invention as detergent surfactants include sulfonates such as those generally disclosed in U.S. Patent 3,929,678, Laughlin et al., issued December 30, 1975, at column 23, line 58 through column 29, line 23 and in U.S. Patent 4,294,710, Hardy et al., issued October 13, 1981. Classes of useful anionic surfactants include: 1. Ordinary alkali metal soaps, such as the sodium, potassium, ammonium and alkylolammonium salts of higher fatty acids containing from 8 to 24 carbon atoms, preferably from 10 to 20 carbon atoms. Preferred alkali metal soaps are sodium laurate, sodium stearate, sodium oleate and potassium palmitate. 2.

Enzymes Enzymes are an optional ingredient generally incorporated in an amount of from 0.025% to 2%, preferably from 0.05% to 1.5% of the total composition. Preferred proteolytic enzymes should provide a proteolytic activity of at least 5 Anson units (about 1,000,000 Delft units) per liter, preferably from 15 to 70 Anson units per liter, most preferably from 20 to 40 Anson units per liter.

Stabilizing System Preferably, the liquid detergent compositions of the present invention contain a stabilizing agent to maintain the fabric care agent uniformly dispersed in the liquid medium. Otherwise, density differences between the insoluble particles and the liquid base detergent can cause eventual particle settling or creaming. The choice of the stabilizing agent for the present compositions depends upon factors such as the type and level of solvent ingredients in the composition. Suitable suspending agents include various clay materials, such as montmorillonite clay, quaternized montmorillonite clays (e.g. Bentone™ 14, available from NL Industries), hectorites (e.g., Laponite™ S, available from La Porte), polysaccharide gums (e.g. xanthan gum available from the Kelco Division of Merck & Co., Inc.), any of several long-chain acyl derivative materials or mixtures of such materials; diethanolamide of a long-chain fatty acid (e.g., PEG 3 lauramide), block polymers of ethylene oxide and propylene oxide (such as Pluronic™ F88 offered by BASF Wyandotte), sodium chloride, ammonium xylene sulfonate, sodium sulfate and polyvinyl alcohol. Other suspending agents found useful are alkanol amides of fatty acids, having from 16 to 22 carbon atoms, preferably from 16 to 18 carbon atoms. Preferred alkanol amides are stearic monoethanolamide, stearic diethanolamide, stearic monoisopropanolamide and stearic monoethanolamide stearate. Other long-chain acyl derivatives include long-chain esters of long-chain alkanol amides (e.g., stearamide DEA distearate, stearamide MEA stearate). The most preferred suspending agents for use in the present invention are quaternized montmorillonite clay and hectorite clay. This suspending agent is preferably present at a level of from 0.1% to 10.0%, preferably from 0.5% to 3.0%. Other Optional Detergent Ingredients Other optional ingredients which can be included in detergent compositions of the present invention, in their conventional art-established levels for use (generally from 0 to 20%), include solvents, hydrotropes, solubilizing agents, processing aids, soil-suspending agents, corrosion inhibitors, dyes, fillers, optical brighteners, germicides, pH-adjusting agents (monoethanolamine, sodium carbonate, sodium hydroxide, etc.), enzyme-stabilizing agents, bleaches, bleach activators and perfumes. Product Formulations Liquid detergent compositions of the present invention comprise a liquid base as previously discussed. The liquid detergent compositions further comprise the ion-pair conditioning agent particles, between 0.1% and 20%, total composition weight basis, and the alkyl sulfate/alkyl ethoxylated sulfate surfactant component in an amount totaling at least 7.0% of the total composition, weight basis and, for practical reasons related to control of excessive sudsing, preferably less than 40%, more preferably less than 25%. The ratios of water and other solvents in the compositions will be determined in part by the resulting state of the fabric care agent. At ambient temperatures, the conditioning particles should be substantially insoluble in the product, and within the particle size specifications heretofore discussed. Also, in preferred executions of the invention, the product desirably is free-flowing across a reasonable temperature range, encompassing the conditions typical for storage and use. The level of the essential alkyl sulfate/alkyl ethoxylated sulfate surfactant component effective for increasing the stability of the conditioning particles is dependent upon the particular type and/or concentration of: conditioning particles; liquid base (particularly if nonaqueous solvents are used); the alkyl sulfate/alkyl ethoxylated sulfate surfactant component; and, if present, builders and other surfactants. Other ingredients not specifically listed herein can also affect ion-pair conditioning particle stability. Fatty acid builders and sulfonate surfactants, such as the linear alkyl benzene sulfonate surfactants, in conjunction with fatty acid builders, nonionic surfactants such as alkyl polyethoxylated alcohols and polar solvents such as monohydric alcohols are particularly aggressive toward the conditioning particles in liquid detergent compositions. Accordingly, a higher concentration of the alkyl sulfate/alkyl ethoxylated sulfate surfactant component will generally be required to effect a significant stability benefit for the conditioning particles when these aggressive detergent ingredients are incorporated into the detergent composition, relative to when such aggressive detergent ingredients are not present in the detergent composition. When significant levels of such aggressive ingredients are present in the detergent compositions, more than 7.0% of the detergent composition should be the alkyl sulfate/alkyl ethoxylated sulfate surfactant component. The pH of the liquid detergent compositions is between 5 and 10, preferably between 5 and 9. The lower limit is present for practical reasons related to cleaning performance of the detergent components conventionally used in liquid laundry detergents and the adverse effect of excessively low pH on many textile materials. The pH should be below 10, however, since higher pH tends to excessively adversely affect the chemical stability of the ion-pair complex component(s) of the conditioning particles. Without being limited to theory and by way of explanation, it is believed that such high pH induces the proton bonded to the amine of the ion-pair complex to deprotonate, thereby disrupting the ionic-bonding necessary for continuity of the complexed ions. Other optional components of liquid detergent compositions include, but are not limited to, colorants, perfumes, bacterial inhibitors, optical brighteners, opacifiers, viscosity modifiers, fabric absorbency boosters, emulsifiers, stabilizers, shrinkage controllers, spotting agents, germicides, fungicides and anti-corrosion agents. One preferred method for making stable, one-phase liquid detergent compositions containing: alkyl sulfate and/or alkyl ethoxylated sulfate anionic surfactant; the conditioning particles of the present invention; cumene, xylene or toluene sulfonate surfactant, or a mixture thereof; a smectite-type clay softener; and a nonionic surfactant produced by condensing ethylene oxide with a straight or branched alkyl chain containing from 8 to 16 carbon atoms, the nonionic surfactant having an HLB of from 8 to 15, consists in mixing the clay in the liquid base at a high rate of shear, for example by mixing at about 150,000 sec⁻¹ with a homogenizer. Suitable homogenizers are available from APV Gaulin, Inc., Everett, Massachusetts. Liquid detergent compositions of this invention can also be adapted to a thru-the-wash laundry article which comprises the liquid base, the conditioning particles and alkyl sulfate/alkyl ethoxylated sulfate surfactant component, with or without other detergent, fabric care or other laundry actives contained within a laundry article which releases the liquid detergent composition in water. These laundry articles include dissolvable laundry products, such as dissolvable pouches. The conditioning agent particles used in the present invention may also comprise nonsilicone waxes in addition to the ion-pair complex(s), as disclosed in European Patent Application 294 894, published Dec. 12, 1988. Particles comprising an amine-organic anion ion-pair complex, and optionally comprising an amine-inorganic anion ion-pair complex and nonsilicone wax can be formed by mixing the components in molten form and then forming particles by the methods discussed above, said method not being intended to exclude other methods for forming particles comprising the aforesaid components. Exemplary nonsilicone waxes include hydrocarbon waxes, such as paraffin wax, and microcrystalline wax. The weight ratio of ion-pair complex(s) to wax is preferably between 1:10 and 10:1. In a laundry method aspect of the invention, typical laundry wash water solutions comprise from 0.1% to 2% by weight of the detergent compositions of the invention. Fabrics to be laundered are agitated in these solutions to effect cleaning, stain removal, and fabric care benefits. A useful method for determining an effective level of alkyl sulfate/alkyl ethoxylated sulfate surfactant component for stabilizing the conditioning particles in a liquid detergent composition is to measure the anti-static performance of the conditioning particles for a laundry load washed in cold water after the composition has been aged at elevated temperatures, and then comparing this performance to an alkyl sulfate/alkyl ethoxylated sulfate-free control composition of otherwise substantially the same ingredients after such control composition has been similarly aged. The detergent compositions of the present invention will impart a statistically significant decrease in static relative to the control compositions. Preferably, a sufficient amount of alkyl sulfate/alkyl ethoxylated sulfate surfactant component is incorporated into the composition such that the static of the laundry load is reduced to less than 40%, preferably less than 25%, of the static for the control laundry load after the alkyl sulfate/alkyl ethoxylated sulfate surfactant component-containing detergent composition and control detergent composition have aged at 90°F (about 32.2°C) for seven days, preferably for 28 days. Static of the laundry load can be determined by measurement of electric charge of the laundry load upon completion of an automatic laundry dryer stage. The electric charge can be measured with the use of a Faraday cage, a measurement device known in the art. Total electric charge should be determined by summing the differences in electric charge measured upon removal of each of the pieces of fabric from the laundry load, until all of the fabric pieces are removed from the Faraday cage. The laundry load for the control and test compositions should be dried under substantially equivalent conditions. Conventional automatic dryer temperature ranges, typically between 110°F (43.3°C) and 180°F (82.2°C) are preferred. Also the automatic dryer is desirably located in an environment having a constant relative humidity, preferably of 20% to 25% at about 70°F (about 21.1°C). The quantity of liquid detergent utilized will be dependent upon the size of the load, strength of the detergent, and degree of cleaning performance desired and should be identical for the control and test loads. The laundry load for the control and test detergent compositions should also be identical as to the types of fabrics included. A significant number of fabric articles should include fabric materials which conventionally become statically charged when dried by automatic laundry dryers. Preferably, a mix of fabrics at least including cotton, polyester, acrylic and nylon is used. The detergent dosage per load of laundry should be determined consistent with the acceptable dosages for laundry detergent usage in the laundry detergent art. The liquid detergent compositions of the invention are particularly suitable for laundry use, but are also suitable for other applications, for example, as conditioning shampoo for hair. The foregoing description fully describes the nature of the present invention. The following examples are presented for the purpose of illustrating the invention. The scope of the invention is to be determined by the claims, which follow the examples. All parts, percentages and ratios herein are by weight unless otherwise specified. EXAMPLES The following examples illustrate the present invention. The scope of the present invention is to be defined by the claims which follow. The abbreviations used are: EXAMPLE I This example demonstrates the synthesis and generation of conditioning particles made from a combination of ditallow amine-linear C₃ alkylbenzene sulfonate (C₃LAS) ion-pair complex and ditallow amine-sulfate ion-pair complex. The ditallow amine-C₃LAS ion-pair complex is formed by combining a 1:1 molar ratio of ditallow amine (available from Sherex Corporation, Dublin, Ohio as Adogen® 240) and cumene sulfonic acid. The acid is slowly added to a 70°C to 150°C melt of the amine with agitation to provide a homogeneous fluid. Distearyl amine, also available from Sherex Corporation, complexed with C₃LAS can be made by substantially the same method. This complex can then be directly prilled to form particles or can be mixed with ditallow amine sulfate ion-pair complex made as described below. The ditallow amine-sulfate ion-pair complex is formed by combining a 2:1 molar ratio of ditallow amine and sulfuric acid. The acid is slowly added to a 70°C to 150°C melt of the amine with agitation to provide a homogeneous fluid. The ditallow amine-C₃LAS complex and the ditallow amine-sulfate complex, respectively, are then mixed together at a weight ratio of 70:30. The ion-pair complex or mixture of ion-pair complexes is kept well mixed by recirculation and hydraulically forced through a heated nozzle to form particles of the complex which have mean diameters of between 50 and 200 micrometers. Alternately, the comelt can be forced through the nozzle by air injection. This method of synthesis and generation of the ditallow amine-C₃LAS particles and the ditallow amine-C₃LAS/ditallow amine-sulfate conditioning particles can also be used to make other amine-organic anion conditioning particles, such as distearyl amine-C₃LAS particles, and other amine-organic anion/ amineinorganic anion ion-pair conditioning particles including, but not limited to, the combinations shown below: Conditioning Particle Ion-Pair Combination Amine-Organic Anion Amine-Inorganic Anion 1. Ditallow amine-C₃LAS Distearyl amine-sulfate 2. Distearyl amine-C₃LAS Distearyl amine-sulfate 3. Distearyl amine-C₃LAS Ditallow amine-sulfate The amine-organic anion to amine-inorganic anion ion-pair complex proportions can be modified to other ratios within the range of 95:5 to 5:95, preferably within the range of 40:60 to 90:10. These particles can be used as disclosed in the following examples by forming the particles as discussed above and then mixing them with the appropriate detergent components. All such compositions can be added to the laundry before or during the wash stage of fabric laundering without significantly impairing cleaning performance, while still providing excellent fabric conditioning.

EXAMPLE VIII A heavy duty liquid laundry detergent composition of the present invention is as follows. Component Weight % Sodium C₁₂₋₁₃ alkyl polyethoxylate (1.0) sulfate 8.5 C₁₂₋₁₃ alcohol polyethoxylate (6.5) 9.7 Sodium cumene sulfonate 4.5 Prills 6.4 Distearyl amine-C₃LAS (70%) Distearyl amine-sulfate (30%) Smectite clay (Bentone 14, organically modified montmorillonite) 1.4 Ethanol 3.4 Sodium formate 1.4 Calcium formate 0.1 Sodium diethylenetriamine pentaacetic acid (DTPA) 0.4 Water and miscellaneous (includes anti-redeposition agent and brighteners) Balance to 100% The process used to make this composition is as follows. The percent activities are given as weight percents in aqueous solution. The ingredients listed in step 1 are added to a mixing tank with a single agitator in the order which they appear above. Before the calcium formate is added, the pH of the mix is lowered to below 9.0 by adding 0.04 parts of citric acid. The clay slurry listed in step 2 is made by mixing the clay into water with an agitator. This clay slurry (step 2) is immediately added to the ingredients from step 1. This formulation intermediate is then processed through a Gaulin Homogenizer at a pressure of 6000 psig, (41.5x10⁶ Pa) shear rate of 150,000 sec⁻¹, and for 1 pass. This processing step is critical to activate the clay as an effective suspension agent. Product mading continues by adding the ingredients listed in step 3, in the order which they appear above, to the formulation intermediate which was processed through the homogenizer. The ingredients are hand mixed at this point. Finally, the prills described in step 4 are added and mixed in by hand, followed by mechanical agitation for less than a minute. The stable one-phase heavy duty liquid has a viscosity of about 480 cps (480 mPas) at 70°F (about 21.1°C), a pH of 9.1, and a yield value of about 146 dynes/cm² (14.6 Pa).
