Description: Detergent compositions Technical field The present invention relates to detergent compositions containing a cationic ester surfactant and perfume, which are suitable for use in laundry and dishwashing methods. The detergent compositions provide an improved perfume fabric substantivity. Background to the invention The satisfactory removal of greasy soils/stains, that is soils/stains having a high proportion of triglycerides or fatty acids, is a challenge faced by the formulator of detergent compositions for use in laundry and dish washing methods. Surfactant components have traditionally been employed in detergent products to facilitate the removal of such greasy soils/stains. In particular, surfactant systems comprising cationic esters have been described for use in greasy soil/stain removal. An aspect of successful formulation of commercial detergent products is measured by the resulting malodour of the cleaned surface and/or laundered fabric, especially after exposure to strong mal odours (such as perspiration, smoke and/or kitchen odours, which are among the most persistent odours on dried cleaned fabrics and/or surfaces). Traditionally, perfumes are employed in detergents to mask these resulting malodour. For example, EP-B-21,491 discloses detergent compositions containing a nonionic/cationic surfactant mixture and a builder mixture comprising aluminosilicate and polycarboxylate builder. The cationic surfactant may be a cationic ester. Improved paniculate and greasy /oily soil removal is described. US-A-4,228,042 discloses biodegradable cationic surfactants, including cationic ester surfactants for use in detergent compositions to provide greasy /oily soil removal. The combination of these cationic surfactants with nonionic surfactants in compositions designed for particulate soil removal is also described. US-A-4,260,529 discloses laundry detergent compositions having a pH of no greater than 11 containing cationic ester surfactant and nonionic surfactant at defined weight ratios. A problem can be that certain perfumes are not able to mask the malodours present in or on the fabric sufficiently during the cleaning or washing process. This amounts to a resulting malodour after the cleaning or washing process. It has been found that a partial solution to this problem can be achieved when perfumes with a high fabric substantivity are employed in the detergents. The fabric substantivity of perfumes is partly determined by their molecular weight and by their functionality/ polarity. It has been found that perfume with a molecular weight of from 150 to 350 have a high fabric substantivity. When these perfumes contain an oxygen comprising functional groups (such as ester, ketone, aldehyde, alcohol and ether groups) their fabric substantivity is further increased. The Applicants have now found an improved solution to the problem described above. Fabric substantivity of the perfumes has been found to be increase when a perfume with a molecular weight of from 150 to 350 and a cationic ester surfactant are employed in a detergent composition. Thus, it has been found that cationic ester surfactants enhance the fabric substantivity of the perfumes, especially when the perfumes contain an oxygen comprising functional groups. Hence, an improved masking of malodours and/or an improved resulting (perfume) odour of the fabric after the wash is provided. The following mechanism is believed to be responsible for the improved perfume substantivity. The perfumes, especially those comprising oxygen containing functional groups, have a high affinity for cationically charged substances, such as positively charged fabric surfaces. Cationic ester surfactants are capable of interacting with a fabric surface to provide a positively charged fabric surface. The perfumes will have an improved fabric substantivity for the fabrics, positively charged by the cationic ester surfactant. It has been found that the use of an cationic ester surfactant thus can provide a surprisingly improved perfume substantivity on the cleaned or washed fabric. All documents cited in the present description are, in relevant part, incorporated herein by reference.

Suitable cationic fabric softening agents include the water insoluble tertiary amines or dilong chain amide materials as disclosed in GB-A-1 514 276 and EP-B-0 Oi l 340. Cationic fabric softening agents are typically incoφorated at total levels of from 0.5 % to 15 % by weight, normally from 1 % to 5 % by weight. 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. pH of the compositions The present compositions preferably have a pH measured as a 1 % solution in distilled water of at least 8.5, preferably from 9.0 to 12.5, most preferably from 9.5 to 11.0. Form of the compositions 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. 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 mean particle size of the components of granular compositions in accordance with the invention 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 cationic ester surfactant herein, preferably with additional surfactants, 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 8211 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. 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. Especially preferred dispensing devices are disclosed in European Patent Application Publication Nos. 0343069 & 0343070. The latter Application discloses a device comprising a flexible sheath in the form of a bag extending from a support ring defining an orifice, the orifice being adapted to admit to the bag sufficient product for one washing cycle in a washing process. 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 arrangemnt 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. 0011500, 0011501, 0011502, and 0011968. A convenient form of water frangible closure comprises a water soluble adhesive disposed along and sealing one edge of a pouch formed of a water impermeable polymeric film such as polyethylene or polypropylene. Packaging for the compositions Commercially marketed executions of the bleaching compositions can be packaged in any suitable container including those constructed from paper, cardboard, plastic materials and any suitable laminates.
