Description: SOLID DETERGENT COMPOSITIONS Technical Field of the Invention The invention relates to solid detergent compositions comprising aluminosilicate builder and surfactants comprised in two or more components which have an improved cleaning performance, an improved delivery to the wash and a reduced residue formation on the fabrics. Background to the Invention All detergents on the market contain surfactants and builders. One of the most commonly used builders in phosphate-free detergents are aluminosilicates. They are inexpensive builders, which have as an additional benefit that they are easy to process. They are in fact useful process aids because they are very good structurants, binders or carrier materials for other detergent ingredients. Therefore, most detergents comprise a base powder, made by spray-drying a slurry of aluminosilicate and surfactant or by agglomerating aluminosilicate and surfactant. Furthermore, aluminosilicates are useful as dusting agent, to reduce the stickiness or caking of the product. A problem encountered with these detergents comprising a builder system containing aluminosilicates, it that they tend to cause fabric residues. These residues contain detergent products which is entrapped in the fabrics and/ or are insoluble in water. They are noticeable by the consumer as spotting on the fabric. Another problem encountered with, in particular solid, detergents is their tendency to gel upon contact with water. This leads to poor dispensing of the product from the dispensing drawer or from a dispensing device, and also to poor dissolution of the product into the wash water. This results in residues in the drawer, dispensing device, washing machine and on the fabrics, which may be noticeable as spots on the fabric. It has been found that in particular surfactants gel upon contact with water. The inventors have now suφrisingly found that this problems in particular arises when the surfactants and the aluminosilicates in the detergent are in close contact with one another, for example when they are in the detergent in an intimately mixture. This is for example the case in most known and used base powders, which are agglomerates or spray-dried powders containing. The inventors have now found that the residue formation problem but also the gelling problem or dissolution or dispensing problem mainly arises in most known products, when about all the anionic surfactants and aluminosilicates are intimately mixed with one another. When the degree of intimate mixing is reduced or even avoided completely, they have found that these problems are reduced or even solved completely. Thus, the inventors have found a solution which still allows the incoφoration of aluminosilicates and surfactants in detergent, but in a different manner: the invention provides thereto detergents comprising at least two components comprising the surfactants and the aluminosilicate in such a manner that a limited degree of intimate mixing occurs. The detergents of the invention have a reduced fabric residue, in particular of insoluble detergent ingredients, gelling, an improved dispensing and dissolution. It has been found that these benefits are obtained by any convention way of introducing detergent to the wash, including by use of a dispensing drawer, a dispensing device or by addition of the detergent in the washing prior to addition of the wash load or addition of the detergent on top of the wash load. The compositions may comprise an effervescence system to further aid the dispensing or dissolution or foaming. Summary of the Invention The invention provides a detergent composition comprising an aluminosilicate builder and an anionic surfactant and comprising (n) components (i), n being at least 2, whereby the level of aluminosilicate builder in said components together is at least 5% by weight of the composition and the level of the anionic surfactant in said components together is at least 5% by weight of the composition, and whereby the degree of mixture (M) of the anionic surfactant and the aluminosilicate builder is from 0 to 0.7, M being ∑ n ι=ι V(σ, . ζ ) σ is the fraction of the anionic surfactant of the composition comprised in component (i); ζ is the fraction of the aluminosilicate of the composition comprised in component (i). The composition is in particular in granular form, in the form of an extrudate, marumerate or pastille, or in the form of an tablet. The invention also relates to the use in a detergent composition of at least two components which comprise together an aluminosilicate at a level of at least 5% by weight of the composition and an anionic surfactant at a level of at least 5% by weight of the composition or mixtures thereof, whereby the degree of mixture (M) of the anionic surfactant and the aluminosilicate builder is from 0 to 0.7 for improvement of the delivery of the detergent to the washing water, M being as defined above. The detergent compositions have an improved delivery to the washing water. This means for the piupose of the invention that the compositions provide a reduction of fabric residues, in particular of water-insoluble detergent ingredients such as the aluminosilicate, an improvement of the dispensing of the detergent composition, an improvement in the dissolution of the detergent, a reduction in gelling of the detergent and / or a reduction of lump formation of the detergent on the fabrics and for bleach-containing compositions, an reduced risk of fabric damage. Detailed Description of the Invention The detergent composition herein comprise at least two components which comprise an anionic surfactant or an aluminosilicate or mixtures thereof, whereby if mixtures of aluminosilicate and the surfactant are present in one or more of the components, the degree of mixture M is less than 0.7, as defined by the formula. Thus, each component comprises part or all of the aluminosilicate, all or part of the anionic surfactant or mixtures thereof, provided that M is from 0 to 0.7. The components of the detergent composition of the invention comprise each at least two ingredients, including the anionic surfactant and/ or the aluminosilicate, which are intimately mixed. This means for the puφose of the invention that the two or more ingredients the component are substantially homogeneously divided in the component. Preferably, a component is such that when it comprises an anionic surfactant, the level of the anionic surfactant is less than 95%), preferably less than 85% or even less than 80% by weight of the component, whereby it may be preferred that the level of the anionic surfactant is at least 5%, preferably at least 10% more preferably at least 20% or even at least 30%) or even 35% by weight of the component. Preferably, a component is such that when it comprises an aluminosilicate, the level of the aluminosilicate is less than 95%), preferably less than 85% or even less than 80% by weight of the component, whereby it may be preferred that the level of the aluminosilicate is at least 5%>, preferably at least 10%> by weight of the component. It should be understood that the detergent composition herein may also comprise additional intimately mixtures which are free of anionic surfactant and free of aluminosilicate. Also, the detergent composition may comprise additional ingredients which are not in an intimate mixture with another ingredient and thus not comprised in a component of the composition, as defined herein. For example, the composition may comprise a detergent ingredient sprayed onto the components herein or dry-added to the components herein. The components together comprise the aluminosilicate builder at a level of least 5%> by weight of the composition of and the anionic surfactant at a level of at least 5%> by weight of the composition. Preferably, the components comprise the aluminosilicate at a level of at least 1%, or more preferably at least 10%> or even 15%> by weight of the composition. Depending on the precise formulation of the composition and the conditions of use, the compositions of the invention can even comprise higher levels of aluminosilicate, such as more than 20%> or even more than 25%>, whilst still providing an improved delivery of the detergent to the wash. Preferably at least 7%> or more preferably at least 10%> or even at least 12%> by weight of the composition of anionic surfactant is present in the components. Depending on the precise formulation of the composition and the conditions of use, it may be preferred to have levels of anionic surfactants of 18%) by weight of the composition or more. It may be preferred that the detergent composition comprises additional dry-added aluminosilicate, in particular to dust the detergent components to reduce the risk of caking and/ or to provide whiteness to the product. Preferably, M is less than 0.65, or even less than 0.45 or even 0.4 or even 0.35. It may be preferred that M is 0, and that thus no components are present in the detergent composition which comprise both aluminosilicate and anionic surfactants. Whether this is preferred will for example depend the levels of aluminosilicate and anionic surfactant in the detergent, on the other ingredients present in the formulation and the amount of components present in the formulation. The components herein preferably are particles, having a particle size of at least 50 microns, preferably the particles have an weight average particle size of more than 150 or more than 250 microns or even more than 350 microns, as measured by sieving the composition on sieves of different mesh size, and calculating the fraction which remain on the sieve and the fraction which passes through the sieve. It may be preferred that at least one component is made by a spray-drying process, as known in the art, and at least one component is made by an agglomeration process, as known in the art. Preferably, the density of the components is from 250 g/litre to 1500 g/litre, more preferably at least one of the components, preferably all of the components, has a density from 400 g/litre to 1200gr/litre, more preferably from 500 g/litre to 900g/litre. A highly preferred additional ingredient of the detergent compositions herein may be oxygen based bleach, preferably containing an hydrogen peroxide source, preferably a perhydrogen compound and a bleach activator, described herein after. It has been found that the improved product delivery to the wash results in an improved delivery of the bleach system therein, which reduces the risk of deposition of bleach on the fabric and the risk of patchy fabric damage. Another preferred additional ingredient is one or more additional builder materials, such as one or more monomeric, oligomeric or polymeric carboxylate builders and/ or crystalline layered silicate builder material, described herein after. Also, depending on the use of the composition and the specific formulation, the detergent composition may be substantially free of specific spray-on nonionic alkoxylated alcohol surfactants, which have been found to cause gelling or dispensing or dissolution problems. It may then be preferred that the composition comprises other nonionic surfactants, preferably nonionic surfactants which are solid at room temperature. A further advantage can be that the omission of sprayed-on nonionic alkoxylated alcohols allows the reduction or omission of powdered materials normally required to dust the detergent particles containing these liquid nonionic surfactants, such as fine aluminosilicates. This not only reduces the process complexity, but moreover reduces the degree of mixing or contact of the s and surfactants. Furthermore, the inventors have found that in certain embodiments of the invention it may be beneficial to reduce the degree of mixing between the aluminosilicate and one or more of the organic polymeric compounds, when present, for example flocculation polymers and polycarboxylate polymers, as described herein. The degree of mixture of the aluminosilicate and one or more of these polymers can be determined by the formula above, wherein σ would indicate the weight fraction of the specific polymer in a certain component. It has been found that this may reduce the fabric residue formation on the fabrics, in particular of water-insoluble components, such as the aluminosilicate. It may also be useful that in certain embodiments of the invention , the degree of mixing between amoφhous silicate and an anionic surfactant is reduced, when an amoφhous silicate is present, in particular in mixtures containing anionic surfactant which are to be spray-dried, it may be beneficial to reduce the amount of silicate present, for example to levels of less than 3% by weight of the mixture, or even less than 2%, or even less thanl% or even 0%> by weight of the mixture.

Other highly preferred suds suppressing systems comprise polydimethylsiloxane or mixtures of silicone, such as polydimethylsiloxane, aluminosilicate and polycarboxylic polymers, such as copolymers of laic and acrylic acid. Polymeric Dye Transfer Inhibiting Agents The compositions herein may also comprise from 0.01%> to 10 %>, preferably from 0.05% to 0.5%) by weight of polymeric dye transfer inhibiting agents. The polymeric dye transfer inhibiting agents are preferably selected from polyamine N- oxide polymers, copolymers of N-vinylpyrrolidone and N-vinylimidazole, polyvinylpyrrolidonepolymers or combinations thereof, whereby these polymers can be cross-linked polymers. Optical Brightener The compositions herein also optionally contain from about 0.005% to 5%> by weight of certain types of hydrophilic optical brighteners, as known in the art. Polymeric Soil Release Agent Polymeric soil release agents, hereinafter "SRA", can optionally be employed in the present compositions. If utilized, SRA's will generally comprise from 0.01% to 10.0%, typically from 0.1 % to 5%, preferably from 0.2% to 3.0%> by weight, of the compositions. Preferred SRA's typically have hydrophilic segments to hydrophilize the surface of hydrophobic fibers such as polyester and nylon, and hydrophobic segments to deposit upon hydrophobic fibers and remain adhered thereto through completion of washing and rinsing cycles, thereby serving as an anchor for the hydrophilic segments. This can enable stains occurring subsequent to treatment with the SRA to be more easily cleaned in later washing procedures. Preferred SRA's include oligomeric terephthalate esters, typically prepared by processes involving at least one transesterification/oligomerization, often with a metal catalyst such as a titanium(IV) alkoxide. Such esters may be made using additional monomers capable of being incoφorated into the ester structure through one, two, three, four or more positions, without, of course, forming a densely crosslinked overall structure. Suitable SRA's include a sulfonated product of a substantially linear ester oligomer comprised of an oligomeric ester backbone of terephthaloyl and oxyalkyleneoxy repeat units and allyl-derived sulfonated terminal moieties covalently attached to the backbone, for example as described in U.S. 4,968,451, November 6, 1990 to J.J. Scheibel and E.P. Gosselink. Such ester oligomers can be prepared by: (a) ethoxylating allyl alcohol; (b) reacting the product of (a) with dimethyl terephthalate ("DMT") and 1 ,2-propylene glycol ("PG") in a two-stage transesterifϊcation/oligomerization procedure; and (c) reacting the product of (b) with sodium metabisulfite in water. Other SRA's include the nonionic end- capped 1 ,2-propylene/polyoxyethylene terephthalate polyesters of U.S. 4,711,730, December 8, 1987 to Gosselink et al., for example those produced by transesterification/oligomerization of poly(ethyleneglycol) methyl ether, DMT, PG and poly(ethyleneglycol) ("PEG"). Other examples of SRA's include: the partly- and fully- anionic-end-capped oligomeric esters of U.S. 4,721,580, January 26, 1988 to Gosselink, such as oligomers from ethylene glycol ("EG"), PG, DMT and Na-3,6-dioxa-8- hydroxyoctanesulfonate; the nonionic-capped block polyester oligomeric compounds of U.S. 4,702,857, October 27, 1987 to Gosselink, for example produced from DMT, methyl (Me)-capped PEG and EG and/or PG, or a combination of DMT, EG and/or PG, Me-capped PEG and Na-dimethyl-5-sulfoisophthalate; and the anionic, especially sulfoaroyl, end-capped terephthalate esters of U.S. 4,877,896, October 31, 1989 to Maldonado, Gosselink et al., the latter being typical of SRA's useful in both laundry and fabric conditioning products, an example being an ester composition made from m- sulfobenzoic acid monosodium salt, PG and DMT, optionally but preferably further comprising added PEG, e.g., PEG 3400. SRA's also include: simple copolymeric blocks of ethylene terephthalate or propylene terephthalate with polyethylene oxide or polypropylene oxide terephthalate, see U.S. 3,959,230 to Hays, May 25, 1976 and U.S. 3,893,929 to Basadur, July 8, 1975; cellulosic derivatives such as the hydroxyether cellulosic polymers available as METHOCEL from Dow; the C1-C4 alkyl celluloses and C4 hydroxyalkyl celluloses, see U.S. 4,000,093, December 28, 1976 to Nicol, et al.; and the methyl cellulose ethers having an average degree of substitution (methyl) per anhydroglucose unit from about 1.6 to about 2.3 and a solution viscosity of from about 80 to about 120 centipoise measured at 20°C as a 2%> aqueous solution. Such materials are available as METOLOSE SMI 00 and METOLOSE SM200, which are the trade names of methyl cellulose ethers manufactured by Shin-etsu Kagaku Kogyo KK. Additional classes of SRA's include: (I) nonionic terephthalates using diisocyanate coupling agents to link polymeric ester structures, see U.S. 4,201,824, Violland et al. and U.S. 4,240,918 Lagasse et al.; and (II) SRA's with carboxylate terminal groups made by adding trimellitic anhydride to known SRA's to convert terminal hydroxyl groups to trimellitate esters. With the proper selection of catalyst, the trimellitic anhydride forms linkages to the terminals of the polymer through an ester of the isolated carboxylic acid of trimellitic anhydride rather than by opening of the anhydride linkage. Either nonionic or anionic SRA's may be used as starting materials as long as they have hydroxyl terminal groups which may be esterified. See U.S. 4,525,524 Tung et al.. Other classes include: (III) anionic terephthalate-based SRA's of the urethane-Iinked variety, see U.S. 4,201,824, Violland et al.; Other Optional Ingredients Other optional ingredients suitable for inclusion in the compositions of the invention include perfumes, speckles, colours or dyes, filler salts, with sodium sulfate being a preferred filler salt.
