Abstract: The invention provides a substantially anhydrous foaming component, capable of providing foaming or sudsing without agitation, comprising intimately mixed, an effervescence component capable of producing a gas upon contact with water, and a substantially anhydrous surface active component, capable of reducing the surface tension.

Description: Foaming component Technical Field This invention relates to a foaming composition useful in any application where foam is required, such as cleaning compositions, pharmaceutical compositions, food and beverages. Background to the Invention Foam formation or sudsing is desired in various applications for different reasons. In detergents, specific surfactants are known to provide sudsing in the washing water. It can be desirable that the foaming or sudsing occurs readily and that the foaming or sudsing has the desired duration. For example, it can be desirable that the effervescence, suds or foam occurs immediately upon contact with water, and that it is stable or continues during use. Furthermore, to maximise the foaming, sudsing or effervescence capacity of these techniques in use upon contact with water, such contact with water or moisture should be avoided during manufacturing or storage. Components which react together upon contact with water to produce effervescence are known detergent ingredients. For example, WO 92/18596 discloses detergents comprising admixed citric acid and sodium carbonate salt as an aid to improve the detergent solubility. Effervescence systems are also widely known in pharmaceutical or agricultural applications, for example as described in GB-A-2, 184,946. The inventors have now found that an effervescence component capable of providing a gas, can be used to produce foaming or sudsing, when used in a specific combination with a surface active component capable of reducing the surface tension, so that controlled, rapid, improved sudsing and/ or foaming is achieved. Upon contact with water, the components comprising the specific effervescence component and the specific surface active component, chemically forms microbubbles, preferably having an average diameter of 200 microns or less. The inventors have found that the formation of these microbubbles enables an improved control of the sudsing or foaming or effervescence, and that it results in improved foaming or sudsing stability, e.g. rapidly formed and stable or long-lasting foam or suds can be obtained. Also, it has been found that the components of the invention provide improved effervescence and dispensing and dissolving of the component or the product comprising the component. Furthermore, it has been found that these components are very stable upon storage. Summary of the Invention The invention provides a substantially anhydrous foaming component capable of providing foaming or sudsing without agitation, comprising intimately mixed, a substantially anhydrous surface active component capable of reducing the air- water surface tension, and an effervescence component capable of formation of a gas upon contact with water. The component or mixtures of different foaming component according to the invention may be used in any application where a method for providing sudsing, foaming or effervescence is useful. In particular, the composition may be used in, preferably solid, cleaning compositions, pharmaceutical products, cosmetic products and solid food or beverage products and the component may be in useful in applications where no agitation or limited agitation is possible or required, such as hand wash detergent compositions and soaking compositions. Detailed description of the invention The foaming component of the invention is capable of providing foaming or sudsing without agitation. It should be understood that for the purpose of the invention, when used herein 'foaming' means any form of formation of gas bubbles, includes sudsing and effervescing.

Other optional ingredients Other optional ingredients suitable for inclusion in the compoennt of the invention or the cleaning compositions herein of include highly preferably perfumes, bleach catalysts, colours and filler salts, with sodium sulfate being a preferred filler salt. pH of the compositions The present foaming component or the cleaning compositions can have an acidic, neutral or an alkaline pH, depending on the application or the additional ingredients comprised in the component or composition. Preferably, the component or the compositions herein have a pH measured as a 1% solution in distilled water, of from 3 to 13.5, preferably least 4.0, preferably from to 12.5, most preferably from 5 to 12.0. Form of the cleaning compositions The cleaning compositions, comprising the component, can be made via a variety of methods, including dry-mixing, extruding, compressing and agglomerating of the various components comprised in the detergent composition. The foaming component of the invention can be present in the cleaning compositions as a separate component of the composition, or can be part of or added to other components or compounds of the compositions. The cleaning compositions can take a variety of physical forms including granular, extrudates tablet or bar forms. The cleaning compositions are particularly the so- called concentrated granular detergent compositions adapted to be added to a washing machine by means of a dispensing drawer or 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 cleaning compositions containing the foaming composition 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 2.5mm in diameter, or even 1.7mm and that 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 cleaning or detergent compositions containing the particulate composition in accordance with the present invention typically have a bulk density of at least 300 g/litre, more preferably from 500 g/litre or even 650g/litre to 1200 g/litre, more preferably to 850 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. The composition is preferably soluble in cold or cool water, i.e. the composition readily dissolves/disperses in water at a temperature between about 0 C and 32.2 C, preferably between about 1.6°C and 10 C. 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 components of the invention or composition comprising the foaming component of 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.
