Description: A Detergent Composition Technical Field The present invention relates to a detergent composition comprising cationic surfactants, hydrophobic peroxyacid bleaching components and a hydrophilic nonionic component. Background to the Invention Amongst consumers there is a need for detergents which provide improved cleaning and stain removal. Different stains can have different properties. Therefore, there is a need to provide detergent compositions which contain various components which together can ensure the removal of all the different stains. Thus, in the last few years detergents have been developed which contain various types of surfactants, such as anionic and cationic surfactants. Furthermore, since certain stains are bleachable, detergent manufacturers have developed bleaches, which can act on the bleachable stains selectively, thus removing the bleachable stains whilst not damaging the fabrics. One type of bleach which is particularly useful therefor is a hydrophobic bleach. However, the use of the variety of different surfactants, bleaches and other detergent ingredients has increased the complexity of the detergent formulations. The various components can interact with each other, thereby influencing each their respective properties. The Applicants have found that a problem encountered with the more complex detergent formulations, can be a reduction of the performance of the individual detergent ingredients. It has been found that the introduction of an additional ingredient to a detergent composition, increasing the complexity of the detergent composition, does not always result in an increased cleaning performance of the final composition, as would be expected. In particular, it has been found that cationic and hydrophobic components, when comprised in a detergent composition, can diminish each others performance. The Applicants have now found that this problem can be ameliorated or solved by the introduction of a hydrophilic nonionic component, especially certain nonionic surfactants, to the detergent composition comprising certain hydrophobic bleaching components and cationic surfactant components. It has been found that the incorporation of a hydrophilic nonionic component to a detergent composition comprising certain cationic surfactants and hydrophobic bleaches, leads to an improved performance of these two latter components, in comparison to detergent compositions which do not comprise the hydrophilic nonionic component. Both the bleach performance and the cleaning performance are unexpectingly increased when a hydrophilic nonionic component is introduced to the composition. This leads to a much improved removal of both bleachable and non-bleachable stains. An additional benefit can be that the levels of the individual components can be reduced, if desired, because a more efficient performance by the individual components is achieved. All documents cited in the present description are, in relevant part, incorporated herein by reference. Summary of the Invention According to the present invention there is provided a detergent composition comprising a) a hydrophobic peroxyacid bleaching component, capable of providing a hydrophobic peroxyacid compound, with the proviso the component does not comprise the sodium salt of nonanoyloxybenzene sulfonate; b) a hydrophilic nonionic component, having a Hydrophilic/ Lipophilic Balance of at least 10.8, as measured by the HLB-test; c) a cationic surfactant component, with the proviso that the cationic surfactant is not a cationic choline ester surfactant or a salt of the cationic C j2 - Cj4 alkyl dimethyl ammonium ethanol surfactant. Detailed Description of the Invention Hydrophilic nonionic component According to the present invention a hydrophilic nonionic surface-active component is present, having a Hydrophilic/ Lipophilic Balance (HLB) of at least 10.8, as measured by the HLB test described herein. To avoid confusion, by using the term 'having a Hydrophilic/ Lipophilic Balance (HLB)' or 'having a HLB' herein is meant that a hydrophilic nonionic surface-active component either has a HLB whereof the value is obtained by the calculation, described below, or has a HLB whereof the value is obtained by the comparison HLB- test, described below. Preferably, the hydrophilic nonionic component has a HLB of at least 1 1, more preferably of at least 1 1.6, most preferably of at least 11.7. The ratio of the cationic surfactant to the hydrophilic nonionic component is generally from 100: 1 to 1 : 100, preferably from 20: 1 to 1 :30, more preferably from 5: 1 to 1 :20, most preferably from 1 : 1 to 1 : 10. The ratio of the hydrophobic peroxyacid bleaching component to the hydrophilic nonionic component is generally from 150: 1 to 1 :100, preferably from 50: 1 to 1 :20, more preferably from 20: 1 to 1 : 10, most preferably from 15: 1 to 1 : 1. Preferably, the hydrophilic nonionic component is present at a level of from 0.01% to 40%, more preferably from 0.5% to 20%, even more preferably from 1.0% to 14%, most preferably from 2.0%) to 8% by weight of the composition. Preferably, the nonionic component has an average molecular weight of from 200 to 2000, more preferably from 250 to 1000, most preferably from 250 to 600. Preferably, the hydrophilic nonionic component is a nonionic surfactant as described below. HLB-test The HLB test serves to determine if a certain nonionic component has a Hydrophilic/ Lipophilic Balance or HLB of at least 10.8 and is therefore, according to the definition used for this invention, a hydrophilic nonionic component for use in the invention. In the HLB-test nonionic components, whereof the HLB can not be calculated by the formula below, are compared to one or more standard nonionic components, whereof the HLB can be obtained by calculation, to thus determine the HLB of the former nonionic component. The procedure to compare the nonionic components with the standard-components is set out below. Any linear nonionic component, consisting of y ethoxylate groups, x carbon atoms, 2x +1 hydrogen atoms and one hydroxy group, whereof the HLB can be calculated by the following formula, can be used as comparison standard nonionic components: HLB = weight % of ethoxylate = 44_y_ x 100 5 44 y + 12 x + 2 x + l +17 5 The comparison between the standard nonionic component and another nonionic component, to obtain its HLB, can be done by gas chromatography, as set out by G E Petrowski and J R Vanatta (Journal of American Oil Chemist's Society, August 1973, volume 50, pages 284-289). With the above formulation the HLB's of linear standard nonionic components, with a purity of 95%, preferably 99%, with different x and y, are calculated. For a good comparison of HLB values, several (preferably at least 6) standard nonionic components whereof the calculated HLB is less, than equal to, and more than 10.8 are to be used. The standard nonionic components and the nonionic component are each coated onto support material (chromosorb W-NAW 60/80 mesh, Jones Chromatography, Wales) and each at a time the coated support materials are packed into a 2 m copper columns (Jones Chromatography, Wales) of a gas chromatograph (Pye Unicam 204, with flame -ionisation detector, carrier gas nitrogen). A mixture of two solvents, one hydrophobic and one hydrophilic, preferably n-octane and butane- 1 -ol, is introduced into each column. The chromatography is conducted at a constant temperature, which is preferably selected such that the nonionic component is liquid. Then the retention time of the two solvents of the mixture is determined, pi and p2, and the ratio (R) of the retention times pi / p2 is calculated. A graph is made of the In R versus the calculated HLB values. An about linear relationship is found between these two values. Then, the procedure above is repeated for each nonionic component, whereof the HLB needs to be determined, by coating it onto support material (chromosorb), using the same mixture of two solvents, and temperature. By measuring the retention times, calculating the In R, and comparing the obtained In R with the graph of the standard nonionic components, it can be determined whether the HBL of this nonionic component is above 10.8, being thus a hydrophilic ionic component in accord with the invention.

Form of the compositions The detergent composition of the invention can be made via a variety of methods, including dry- mixing and agglomerating of the various compounds comprised in the detergent composition. The acid source of the invention is preferably dry-added as a separate component. The compositions in accordance with the invention can take a variety of physical forms including granular, tablet, bar and liquid forms. The compositions are particularly the so-called concentrated granular detergent compositions adapted to be added to a washing machine by means of a dispensing device placed in the machine drum with the soiled fabric load. The mean particle size of the base composition of granular compositions in accordance with the invention can be from 0.1 mm to 5.0 mm, but it should preferably be such that no more that 5% of particles are greater than 1.7mm in diameter and not more than 5% of particles are less than 0.15mm 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 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 600 g/litre, more preferably from 650 g/litre to 1200 g/litre. 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. Surfactant agglomerate particles The surfactant system herein is preferably present in granular compositions in the form of surfactant agglomerate particles, which may take the form of flakes, prills, marumes, noodles, ribbons, but preferably take the form of granules. The most preferred way to process the particles is by agglomerating powders (e.g. aluminosilicate, carbonate) with high active surfactant pastes and to control the particle size of the resultant agglomerates within specified limits. Such a process involves mixing an effective amount of powder with a high active surfactant paste in one or more agglomerators such as a pan agglomerator, a Z-blade mixer or more preferably an in-line mixer such as those manufactured by Schugi (Holland) BV, 29 Chroomstraat 821 1 AS, Lelystad, Netherlands, and Gebruder Lodige Maschinenbau GmbH, D- 4790 Paderborn 1, Elsenerstrasse 7-9, Postfach 2050, Germany. Most preferably a high shear mixer is used, such as a Lodige CB (Trade Name). A high active surfactant paste comprising from 50% by weight to 95% by weight, preferably 70% by weight to 85% by weight of surfactant is typically used. The paste may be pumped into the agglomerator at a temperature high enough to maintain a pumpable viscosity, but low enough to avoid degradation of the anionic surfactants used. An operating temperature of the paste of 50°C to 80°C is typical. In an especially preferred embodiment of the present invention, the detergent composition has a density of greater than about 600 g/1 and is in the form of powder or a granulate containing more than about 5% by weight of the alkali, preferably (bi-) carbonate or percarbonate. The carbonate material is either dry-added or delivered via agglomerates. The acid, preferably citric acid, (preferably up to 10%) may be introduced into the product as a dry-add as a separate compound, or as a part of the agglomerate mix. 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 40g 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 a dispensing device is employed in the washing method. The dispensing device is charged with the detergent product, and is used to introduce the product directly into the drum of the washing machine before the commencement of the wash cycle. Its volume capacity should be such as to be able to contain sufficient detergent product as would normally be used in the washing method. Once the washing machine has been loaded with laundry the dispensing device containing the detergent product is placed inside the drum. At the commencement of the wash cycle of the washing machine water is introduced into the drum and the drum periodically rotates. The design of the dispensing device should be such that it permits containment of the dry detergent product but then allows release of this product during the wash cycle in response to its agitation as the drum rotates and also as a result of its contact with the wash water. To allow for release of the detergent product during the wash the device may possess a number of openings through which the product may pass. Alternatively, the device may be made of a material which is permeable to liquid but impermeable to the solid product, which will allow release of dissolved product. Preferably, the detergent product will be rapidly released at the start of the wash cycle thereby providing transient localised high concentrations of product in the drum of the washing machine at this stage of the wash cycle. Preferred dispensing devices are reusable and are designed in such a way that container integrity is maintained in both the dry state and during the wash cycle. Especially preferred dispensing devices for use with the composition of the invention have been described in the following patents; GB-B-2, 157, 717, GB-B-2, 157, 718, EP-A-0201376, EP-A-0288345 and EP-A- 0288346. An article by J.Bland published in Manufacturing Chemist, November 1989, pages 41-46 also describes especially preferred dispensing devices for use with granular laundry products which are of a type commonly know as the "granulette". Another preferred dispensing device for use with the compositions of this invention is disclosed in PCT Patent Application No. W094/11562.

A portion of the washing medium flows through the orifice into the bag, dissolves the product, and the solution then passes outwardly through the orifice into the washing medium. The support ring is provided with a masking arrangement to prevent egress of wetted, undissolved, product, this arrangement typically comprising radially extending walls extending from a central boss in a spoked wheel configuration, or a similar structure in which the walls have a helical form. Alternatively, the dispensing device may be a flexible container, such as a bag or pouch. The bag may be of fibrous construction coated with a water impermeable protective material so as to retain the contents, such as is disclosed in European published Patent Application No. 0018678. Alternatively it may be formed of a water-insoluble synthetic polymeric material provided with an edge seal or closure designed to rupture in aqueous media as disclosed in European published Patent Application Nos. 001 1500, 001 1501, 001 1502, and 001 1968.
