Description: Detergent compositions Technical Field The present invention relates to detergent compositions which comprise low levels of inorganic sulphate salts, but instead high levels of carbonate salts and a system to counter balance the effects of the carbonate salt. Background to the Invention Many detergent compositions comprise filler salts such as sodium sulphate. Certain formulations even comprise very high levels of such sulphate salts, in particular low density products sometimes comprise more than 30% by weight of sulphates. However, it is desirable to reduce the level of inorganic sulphates in the products, in particular from an environmental point of view. To replace the inorganic sulphate salts, other inorganic materials can be used. Some of these materials may for example be detergent builders including zeolites, phosphates or silicates. However, these ingredients may increase the formulation cost significantly. Also, high levels of phosphates as fillers are not acceptable in all countries for environmental reasons. Other, cheaper inorganic materials include for example inorganic carbonate salts, which can be readily formulated in detergents. They have as additional benefit that they provide a high alkalinity which is advantageous for the detergency. However, the inventors have found that formulations comprising high levels of inorganic carbonate salts can cause hardness or stiffiiess to the fabrics washed with these products. Therefore, the inventors found that the products need to contain a system to counteract the fabric hardness or stiffness. Numerous compounds are known in the art which can provide a softer feel of fabrics. However, they are not always compatible with high amounts of carbonate salts. The inventors now found that in particular certain mineral clays can help to overcome the problems caused by the high levels of carbonate salts. However, they found that a clay alone would not be sufficient to provide the required softness when these high amount of carbonate salts are present, but that a flocculating agent is required as well. Clays and flocculants are known in the art to provide softness to fabrics. They are for example described in EP 313146- A. However, it was previously not known that the clays and flocculating agents can counteract the disadvantages of high levels of carbonate. Summary of the invention The invention relates to a detergent composition comprising a) a clay; b) a flocculating agent; c) at least 18%, preferably at least 20% by weight of an alkali and/ or earth alkali salt of carbonate. The invention also relates to the use of a clay and a flocculating agent compositions comprising 18% by weight or more of alkali and or earth alkali carbonate salt. The compositions preferably comprise low levels of sulphate. The compositions are useful for both automatic washing and hand washing, including also pre-treatment, soaking and conditioning. Carbonate salts The carbonate salts for use herein include any carbonate salts, but are in particular alkali and/ or earth alkali carbonate salts, in particular carboante, bicarbonate and sesquicarbonate salts. Preferred salts include carbonate, sesqiocarbonate and hydrogen carbonate of potassium, lithium, sodium, and the like amongst which sodium and potassium carbonate are preferred. Suitable bicarbonates to be used herein include any alkali metal salt of bicarbonate like lithium, sodium, potassium and the like, amongst which sodium and potassium bicarbonate are preferred. However, the choice of carbonate or bicarbonate or mixtures thereof in the dry effervescent granules may be made depending on the pH desired in the aqueous medium wherein the granules are dissolved. For example where a relative high pH is desired in the aqueous medium (e.g., above pH 9.5) it may be preferred to use carbonate alone or to use a combination of carbonate and bicarbonate wherein the level of carbonate is higher than the level of bicarbonate. The inorganic alkali and/ or earth alkali carbonate salt of the compositions of the invention comprises preferably a potassium or more preferably a sodium salt of carbonate and/ or bicarbonate. Preferably, the carbonate salt comprises sodium carbonate, optionally also a sodium bicarbonate. The inorganic carbonate salts herein are preferably present at a level of at least 20% by weight of the composition. Preferably they are present at a level of at least 23% or even 25%o or even 30% by weight, preferably up to about 60% by weight or more preferably up to 55%) or even 50% by weight. They may be added completely or partially as separate powdered or granular component, as co-granules with other detergent ingredients, for example other salts or surfactants. In solid detergent compositions of the invention, they may also completely or partially be present in detergent granules such as agglomerates or spray dried granules. In one embodiment of the invention, an effervescence source is present, preferably comprising an organic acid, such as carboxylic acids or aminoacids, and a carbonate. Then it may be preferred that part or all of the carbonate salt herein is premixed with the organic acid, and thus present in an separate granular component. The carbonate may have any particle size. In one embodiment, in particular when the carbonate salt is present in a granule and not as separately added compound, the carbonate salt has preferably a volume median particle size from 5 to 375 microns, whereby preferably at least 60%>, preferably at least 70% or even at least 80%> or even at least 90% by volume, has a particle size of from 1 to 425 microns. More preferably, the carbonate salt particles has a volume median particle size of 10 to 250, whereby preferably at least 60 %, or even at least 70% or even at least 80%> or even at least 90% by volume, has a particle size of from 1 to 375 microns; or even preferably a volume median particle size from 10 to 200 microns, whereby preferably at least 60 %>, preferably at least 70% or even at least 80% or even at least 90%> by volume, has a particle size of from 1 to 250 microns. In particular when the carbonate salt is added as separate component, so to say 'dry- added' or admixed to the other detergent ingredients, the carbonate may have any particle size, including the above specified particle sizes, but preferably at least an volume average particle size of 200 microns or even 250 microns or even 300 microns. It may be preferred that the carbonate salt of the required particle size is obtained by grinding a larger particle size material, optionally followed by selecting the material with the required particle size by any suitable method. Whilst percarbonate salts may be present in the compositions of the invention as a bleaching agent, they are not included in the carbonate salts as defined herein Clay The compositions of the invention contain a clay, preferably present at a level of from 0.05%) to 40%, more preferably from 0.5% to 30%, most preferably from 2% to 20% by weight of the composition. For clarity, it is noted that the term, as used herein, excludes sodium aluminosilicate zeolite builder compounds, which however, may be included in the compositions of the invention as optional components. The weight ratio of clay to the flocculating polymer is preferably from 1000:1 to 1:1, more preferably from 500:1 to 1:1, most preferably from 300:1 to 1:1, or even more preferably from 80:1 to 10:1, or in certain applications even from 60:1 to 20:1. One preferred clay may be a bentonite clay. Highly preferred are smectite clays, as for example are disclosed in the US Patents No.s 3,862,058 3,948,790, 3,954,632 and 4,062,647 and European Patents No.s EP-A-299,575 and EP-A-313,146 all in the name of the Procter and Gamble Company. The term smectite clays herein includes both the clays in which aluminium oxide is present in a silicate lattice and the clays in which magnesium oxide is present in a silicate lattice. Typical smectite clay compounds include the compounds having the general formula Al2(Si2θ5)2(OH)2-nH2θ and the compounds having the general formula Mg3(Si2θ5)2(OH)2.nH2θ. Smectite clays tend to adopt an expandable three layer structure. Specific examples of suitable smectite clays include those selected from the classes of the montmorillonites, hectorites, volchonskoites, nontronites, saponites and sauconites, particularly those having an alkali or alkaline earth metal ion within the crystal lattice structure. Sodium or calcium montmorillonite are particularly preferred. Suitable smectite clays, particularly montmorillonites, are sold by various suppliers including English China Clays, Laviosa, Georgia Kaolin and Colin Stewart Minerals. Clays for use herein preferably have a largest particle dimension of from 0.01 μm to 800μ m, more preferably from 1mm to 400 mm, most preferably from 5mm to 200 mm. Particles of the clay mineral compound may be included as components of agglomerate particles containing other detergent compounds. Where present as such components, the term "largest particle dimension" of the clay mineral compound refers to the largest dimension of the clay mineral component as such, and not to the agglomerated particle as a whole. Substitution of small cations, such as protons, sodium ions, potassium ions, magnesium ions and calcium ions, and of certain organic molecules including those having positively charged functional groups can typically take place within the crystal lattice structure of the smectite clays. A clay may be chosen for its ability to preferentially absorb one cation type, such ability being assessed by measurements of relative ion exchange capacity. The smectite clays suitable herein typically have a cation exchange capacity of at least 50 meq/lOOg. U.S. Patent No. 3,954,632 describes a method for measurement of cation exchange capacity. The crystal lattice structure of the clay mineral compounds may have, in a preferred execution, a cationic fabric softening agent substituted therein. Such substituted clays have been termed 'hydrophobically activated' clays, as for example sold under the tradename Claytone EM by English China Clays International. The cationic fabric softening agents are typically present at a weight ratio, cationic fabric softening agent to clay, of from 1 :200 to 1 : 10, preferably from 1 : 100 to 1 :20. Suitable cationic fabric softening agents include the water insoluble tertiary amines or dilong chain amide materials as disclosed in GB-A-1 514276 and EP-B-0 011 340. Organophilic clays may also be used herein. These are are hydrophobically modified clays which have organic ions replacing inorganic metal ions by ion exchange processes known in the art. These kinds of clay are readily mixable with organic solvent and have the capability to absorb organic solvent at the interlayers. Suitable examples or organophilic clays useful in the invention are Bentone SD-1, SD-2 and SD-3 from Rheox of Highstown, N.J. In a highly preferred embodiment of the invention, the clay is present in an intimate mixture or in a particle with a humectant and a hydrophobic compound, preferably a wax or oil, such as paraffin oil. Preferred humectants are organic compounds, including propylene glycol, ethylene glycol, dimers or trimers of glycol, most preferably glycerol. The particle is preferably an agglomerate. Alternatively, the particle may be such that the wax or oil and optionally the humectant form an encapsulate on the clay or alternatively, the clay be a encapsulate for the wax or oil and the humectant. It may be preferred that the particle comprises an organic salt or silica or silicate. However, in another embodiment of the invention, the clay is preferably mixed with one or more surfactants and optionally builders and optionally water, in which case the mixture is preferably subsequently dried. Preferably, such a mixture is further processed in a spray-drying method to obtain a spray dried particle comprising the clay. It may be preferred that the flocculating agent is also comprised in the particle or granule comprising the clay. It may be highly preferred that the clay, and optionally also the flocculating polymer, is present in a mixture with a wax and a structering agent. Examples of suitable structuring agents which can be used in particles comprising the clay herein include relatively small hydrophobic solid particles such as hydrophobic silica and relatively high molecular weight hydrocarbons such as hydrocarbon rubber. Hydrophobic silicas are silica particles with a hydrophobic group chemically attached to the surface of the particles. Silica particles can be hydrophobically modified with organic group such as silicone by treating the silica particles with a reactive organosilicon compound. Examples are Cab-O-Sil TS720 and TS530 available from Cabot Corporation and Aerosil 200 supplied by Degussa Corp. The submicron hydrophobic fumed silicas such as those supplied by Cabot Co. under the trademarks Cab-O-Sil TS720 and TS530 are especially preferred. High molecular weight hydrocarbons include homo- or copolymers of ethylene, propylene and butadiene having a molecular weight of about 50,000 to about 5,000,000. Suitable examples include Ortheleium® polyethylenepropylne elastomers supplied by DuPont Corporation. Examples of suitable waxes which can be present in the particles containing the clay, or be mixed with the clay, are commercially available include (1) paraffin wax such as Merck 7150, Merck 7151 supplied by E. Merck or Darmsteadt Germany; Boler 1397, Boler 1538 supplied by Boler of Wayne, Pa, and Ross 115/120 or 1365 supplied by Frank D Ross Co of Jersey City N.J.; (2) Beeswax and (3) Japan Wax also supplied by Frank P Ross Co.

The clay flocculating agent functions such as to bring together the particles of clay compound in the wash solution and hence to aid their deposition onto the surface of the fabrics in the wash. This functional requirement is hence different from that of clay dispersant compounds which are commonly added to laundry detergent compositions to aid the removal of clay soils from fabrics and enable their dispersion within the wash solution. Preferred as clay flocculating agents herein are organic polymeric materials having an average weight of from 100,000 to 10,000,000, preferably from 150,000 to 5,000,000, more preferably from 200,000 to 2,000,000.

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 transesterification/oligomerization procedure; and (c) reacting the product of (b) with sodium metabisulfite in water.

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%o 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. Also highly preferred are polysaccheride polymers. 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-linked 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, colours and other filler salts as replacement for sulphate filler salt.
