Description: Detergent Compositions Technical field The present invention relates to granular detergent compositions and in particular phosphate-containing detergent compositions, which comprise a specific hydrophobic peroxyacid bleaching system and a specific anionic surfactant system. The compositions are suitable for use in laundry washing methods. Background to the Invention In the past decades research efforts have been directed towards the development of bleaching systems, based on organic peroxyacids, which can provide effective stain and/or soil removal from fabrics at lower wash temperatures. The organic peroxyacids are often obtained by the in situ perhydrolysis of organic peroxyacid bleach precursor compounds (bleach activators). A commonly employed precursor compound is tetraacetyl ethylene diamine (TAED) which provides effective hydrophilic cleaning especially on beverage stains. Further organic peroxyacid precursors have thus been developed to deal with hydrophobic stains and soils. However, to achieve effective bleaching of a detergent, both hydrophobic and hydrophilic stains need to be bleached by the bleach system. Furthermore, to achieve an effective or efficient bleach system, the system should provide excellent bleaching at low levels, thereby minimizing the chance of damage to the fabrics. Thus, there is a need to provide detergent compositions which comprise low levels of a bleaching system, containing a bleach system, which has a very effective bleaching performance, having an excellent performance at both hydrophobic soils and hydrophilic soils. Most conventional detergent compositions contain mixtures of various detersive surfactant components. Commonly encountered surfactant components include various anionic surfactants, especially the alkyl benzene sulphonates, alkyl sulfates, alkyl alkoxy sulfates and various nonionic surfactants, such as alkyl ethoxylates and alkylphenol ethoxylates. The inventors have now surprisingly found that the introduction in detergent compositions comprising a hydrophobic bleaching system and one or more mono- functionalised anionic sulphate or/and sulphonate surfactant components, of specific anionic surfactants, which are relatively more-functionalised, results in an improved cleaning performance. Namely, in particular, anionic surfactants which are more- functionalised because they have more than one anionic charge or they have hydrophilic (substituent) groups or they have another anionic charge which is not a head group, have been found to improve the bleaching and cleaning performance of the detergent compositions containing a specific hydrophobic bleaching system and the additional mono-functionalised anionic surfactant. Without wishing to be bound by theory, it is believed that the use of relatively hydrophilic anionic surfactant facilitates the selective migration of one or more of the components of the hydrophobic bleaching system to the bleachable stains or soils specifically. It is believed that these more-functionalised anionic surfactant form effectively CO- micelles with the hydrophobic bleaching system, more easily than mono- functionalised surfactants. It is believed that this can facilitate the dissolution/dispersion of the hydrophobic bleaching system. Thereby, these components can efficiently bleach both hydrophilic and hydrophobic soils. Thus, a low level of the hydrophobic bleaching system and the specific surfactant system can be used to achieve efficient and excellent bleaching and cleaning performance. Furthermore, surprisingly it has been found that the cleaning performance of these detergent compositions is achieved for a wide variety of stains and soils.

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 incorporated 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 transesterification/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-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 colours and filler salts, with sodium sulfate being a preferred filler salt. Highly preferred compositions preferably contain from about 2% to about 10%> by weight of an organic citric acid, preferably citric acid.

Form of the Compositions The detergent component of the invention can be made via a variety of methods, including dry-mixing and agglomerating of the various compounds comprised in the detergent component. The detergent component preferably forms part of a detergent composition. The compositions in accordance with the invention can take a variety of physical forms including liquid and solid forms such as tablet, flake, pastille and bar, and preferably granular forms. The compositions in accord with the present invention can also be used in or in combination with bleach additive compositions, for example comprising chlorine bleach, as mentioned above. However, since preferred detergent compositions of the invention are solid, most liquid chlorine-based bleaching will not be suitable for these detergent compositions and only granular or powder chlorine-based bleaches will be suitable. Alternatively, the detergent compositions can be formulated such that they are chlorine-based bleach-compatible, thus ensuring that a chlorine based bleach can be added to the detergent composition by the user at the beginning or during the washing process. The chlorine-based bleachis such that a hypochlorite species is formed in aqueous solution. The hypochlorite ion is chemically represented by the formula OCT. Those bleaching agents which yield a hypochlorite species in aqueous solution include alkali metal and alkaline earth metal hypochlorites, hyposchlorite addition products, chloramines, chlorimines, chloramides, and chlorimides. Specific examples of compounds of this type include sodium hypochlorite, potassium hypochlorite, monobasic calcium hypochlorite, dibasic magnesium hypochlorite, chlorinated trisodium phosphate dodecahydrate, potassium dichloroisocyanurate, sodium dichloroisocyanurate sodium dichloroisocyanurate dihydrate, trichlorocyanuric acid, l,3-dichloro-5,5-dimethylhydantoin, N-chlorosulfamide, Chloramine T, Dichloramine T, chloramine B and Dichloramine B. A preferred bleaching agent for use in the compositions of the instant invention is sodium hypochlorite, potassium hypochlorite, or a mixture thereof. A preferred chlorine- based bleach can be Triclosan (trade name). Most of the above-described hypochlorite-yi elding bleaching agents are available in solid or concentrated form and are dissolved in water during preparation of the compositions of the instant invention. Some of the above materials are available as aqueous solutions. In general, granular detergent compositions in accordance with the present invention can be made via a variety of methods including dry mixing, spray drying, agglomeration and granulation. The quaternised clay-soil removal/ anti-redeposition agent in accord with the present invention can be added to the other detergent components by dry-mixing, agglomeration (preferably combined with a carrier material) or as a spray-dried component. The mean particle size of the components of granular compositions in accordance with the invention, should preferably be such that no more that 25%) of the particles are greater than 1.8mm in diameter and not more than 25 %> of the particles are less than 0.25mm in diameter. Preferably the mean particle size is such that from 10% to 50%) of the particles has a particle size of from 0.2mm to 0.7mm in diameter. The term mean particle size as defined herein is calculated by sieving a sample of the composition into a number of fractions (typically 5 fractions) on a series of sieves, preferably Tyler sieves. The weight fractions thereby obtained are plotted against the aperture size of the sieves. The mean particle size is taken to be the aperture size through which 50% by weight of the sample would pass. The bulk density of granular detergent compositions in accordance with the present invention typically have a bulk density of at least 200 g/litre, more preferably from 300 g/litre to 1200 g/litre, more preferably from 300g/litre to 800 gr/litre, most preferably from 330 g/litre to 600 gr/ lite. Bulk density is measured by means of a simple funnel and cup device consisting of a conical funnel moulded rigidly on a base and provided with a flap valve at its lower extremity to allow the contents of the funnel to be emptied into an axially aligned cylindrical cup disposed below the funnel. The funnel is 130 mm high and has internal diameters of 130 mm and 40 mm at its respective upper and lower extremities. It is mounted so that the lower extremity is 140 mm above the upper surface of the base. The cup has an overall height of 90 mm, an internal height of 87 mm and an internal diameter of 84 mm. Its nominal volume is 500 ml. To carry out a measurement, the funnel is filled with powder by hand pouring, the flap valve is opened and powder allowed to overfill the cup. The filled cup is removed from the frame and excess powder removed from the cup by passing a straight edged implement eg; a knife, across its upper edge. The filled cup is then weighed and the value obtained for the weight of powder doubled to provide a bulk density in g/litre. Replicate measurements are made as required. Laundry Washing Method Machine laundry methods herein typically comprise treating soiled laundry with an aqueous wash solution in a washing machine having dissolved or dispensed therein an effective amount of a machine laundry detergent composition in accord with the invention. By an effective amount of the detergent composition it is meant from lOg to 300g of product dissolved or dispersed in a wash solution of volume from 5 to 65 litres, as are typical product dosages and wash solution volumes commonly employed in conventional machine laundry methods. In a preferred use aspect the detergent composition is formulated such that it is suitable for hand washing. In another preferred aspect the detergent composition is a pre-treatment or soaking composition, to be used to pre-treat or soak soiled and stained fabrics.
