Description: DETERGENT COMPOSITION COMPRISING LIPOXIDASE ENZYMES This invention relates to detergent compositions, including dishwashing and laundry compositions, containing a lipoxidase enzyme. The overall performance of a detergent product, for use in washing or cleaning method, such as a laundry or dishwashing method, is judged by a number of factors, including the ability to remove soils, and the ability to prevent the redeposition of the soils, or the breakdown products of the soils on the articles in the wash. Food soils are often difficult to remove effectively from a soiled substrate. Bleachable soils derived from fruit and/or vegetable juices are particularly challenging soils to remove. Specific examples of such soils would include hydrophobic bleachable food soils, particularly those having carotenoid chromophores, hereinafter referred to as carotenoid soils. Carotenoid soils can be derived from carrots and tomatoes, and any processed products containing these components as well as certain tropical fruits and saffron. Lipoxidase enzymes are used in the baking industry to oxidize naturally occurring yellow carotene pigment in the flour. The value of the use of lipoxidase enzymes in detergent formulations, particularly those designed for use in laundry, dishwashing and household cleaning operations has not been previously recognized. The Applicants have now found that lipoxidase enzymes provide bleachable stain/soil removal benefits when included as components of detergent compositions. The removal of hydrophobic bleachable food soils, particularly those containing carotenoids is especially enabled. Another problem arising during certain washing operations is the redeposition of coloured/bleachable food soils from the wash solution onto other articles in the wash or onto the vessel containing the wash solution. Said vessel may, where the wash method is a manual dishwashing method, be a bowl or the kitchen sink, or alternatively may be a laundry or automatic dishwashing machine. The problem is particularly noticeable when the washload includes articles soiled by foods naturally containing significant levels of highly coloured carotenoid soils. The Applicant has • found that plastic articles in the wash, and areas of the interior of the wash vessel which are made of plastic material, are particularly susceptible to the deposition of coloured food soils from the wash solution. Said soils can interact with the surface of such plastic substrates producing staining which can be very difficult to remove. A general solution to the problem of bleachable food soil deposition is to bleach the fugitive soils in the wash solution before they have the opportunity to be transferred to other articles in the wash. The Applicant has now found that lipoxidase enzymes may be used to provide bleaching of such fugitive coloured/bleachable food soils, and thus to inhibit the transfer of these soils to other available substrates. The use of a lipoxidase enzyme for this purpose has not been disclosed in the art. The Applicants have also found that the inclusion of a lipoxidase enzyme into a colourless liquid detergent composition aids bleaching of any coloured inpurities, and thus helps maintain the colourless and clear nature of the composition. It is an object of the present invention to provide detergent compositions containing a lipoxidase enzyme, which provide soil/stain removal benefits, when used cleaning and washing operations. It is a related object of the present invention to provide laundry and dishwashing detergent compositions containing a lipoxidase enzyme, which provide enhanced carotenoid soil/stain removal. It is a further object of the present invention to provide the use of a lipoxidase enzyme to inhibit the transfer of a bleachable food soil from an aqueous wash solution to a substrate in a washing method. Summary of the Invention According to the present invention there is provided a detergent composition comprising at least one detergent component selected from a surfactant and a builder compound characterized in that said composition contains a lipoxidase enzyme. Lipoxidase enzyme An essential component of the detergent compositions of the invention is a lipoxidase enzyme. The lipoxidase enzyme is preferably incorporated into the compositions in accordance with the invention at a level of from 0.0001% to 2%, preferably from 0.0005% to 0.5%, more preferably from 0.001% to 0.05% active enzyme by weight of the composition. By lipoxidase enzyme it is meant herein an enzyme which acts to oxidise polyunsaturated fatty acids to their corresponding hydroperoxide form. Lipoxidase enzymes are sometimes called linoleate: oxygen oxidoreductases. Carotenase is a specific example of a lipoxidase enzyme. Lipoxidase enzymes herein include naturally derived lipoxidase enzymes and any variants obtained by, for example, genetic engineering techniques. Any such variants may be specifically designed with regard to the optimization of performance efficiency in the detergent compositions of the invention. For example, variants may be designed such that the stability of the enzyme to commonly encountered components of such compositions is increased. Alternatively, the variant may be designed such that the optimal pH or temperature performance range of the enzyme variant is tailored to suit the particular detergent application. Lipoxidase enzymes may be derived from soya beans. Commercially available lipoxidase enzymes include those sold by ICN Biochemicals. Bleachable food soil transfer inhibition According to another aspect of the present invention the lipoxidase enzyme is used in a washing method for the purpose of inhibiting the transfer of bleachable food soils from an aqueous wash solution to a substrate surface. By bl-eachable soils it is meant essentially any coloured food soils which may be decolourised by the action of bleach. The present invention is most especially concerned with the prevention of transfer of hydrophobic bleachable food soils, particularly those having carotenoid chromophores, such as beta-carotene, lycopene, zeaxanthin or capsanthin, hereinafter referred to generically as carotenoid soils. Carotenoid soils can be derived from carrots and tomatoes, and any processed products containing these components as well as certain tropical fruits and saffron. The Applicant has found that the substrate material which is most prone to receipt of the transfer of bleachable food soils is plastic material, such as polypropylene, polyethylene, polystyrene (including alkyl butyl styrene) or PVC. Such plastic substrate material may interact with any bleachable food soils on the substrate surface to produce persistent staining of the substrate. This staining is particularly visible on translucent plastic material, as is commonly employed for food storage boxes and tubs. Detergent components The compositions of the invention contain at least one detergent component selected from a surfactant and a builder compound. The detergent compositions of the invention may also contain additional detergent components. The precise nature of these additional components, and levels of incorporation thereof will depend on the physical form of the composition, and the nature of the cleaning operation for which it is to be used. The compositions of the invention may for example, be formulated as manual and machine dishwashing compositions, hand and machine laundry detergent compositions including laundry additive compositions and compositions suitable for use in - the pretreatment of stained fabrics, rinse aid compositions, and compositions for use in general household cleaning operations.

Surfactant system The detergent compositions of the invention may contain as a principal detergent component a surfactant selected from anionic, cationic, nonionic ampholytic, amphoteric and zwitterionic surfactants and mixtures thereof.

More preferred levels of incorporation are 0.5% to 35% by weight, most preferably from 0.5% to 20% by weight of machine dishwashing, laundry, and rinse aid compositions in accord with the invention, and from 5% to 60% by weight, more preferably from 15% to 45% by weight of manual dishwashing compositions in accord with the invention. The- surfactant is preferably formulated to be compatible with enzyme components present in the composition. In liquid or gel compositions the surfactant is most preferably formulated such that it promotes, or at least does not degrade, the stability of any enzyme in these compositions.
