Description

CLEANING COMPOSITIONS COMPRISING XYLAN DEGRADING
ALKALINE ENZYME AND BLEACHING AGENT

Field of the Invention The present invention relates to cleaning compositions, including laundry, dishwashing, household cleaning and oral/dental compositions, comprising a xylan degrading alkaline enzyme and a bleaching agent.
Background of the invention Performance of a detergent product, for use in washing or cleaning 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.
Removal by detergents of stains stemming from plants, wood, mould-clay based soil and fruits is on of the thoughest cleaning challenge.
3o Especially in the laundry processes wherein the tendency is to move to low wash temperatures and shorter washing cycles. These stains typically - contain complex mixtures of fibrous material, based mainly on carbohydrates and their derivatives, fibre and cell wall components.
Moreover, such stains are generally accompanied by amyiose, sugars and their derivatives. Specific examples of such soils would include orange, tomato, banana, tea, mango, broccoli, spinash soils and grass.

In particular, food soils are often difficult to remove effectively from a soiled item. Highly coloured or 'dried-on' soils derived from fruit and/or vegetables are particularly challenging soils to remove. Indeed processed or cocked vegetables and fruits often contain non-plant cell walls materials used for the processing, cooking and flavouring of the food : butter, milk, eggs, oils such as soya or olive oil, thickeners, sweeteners such as sugar.
These material are often based on proteins, fats and/or starches.
Moreover, the colored plant and fruit stains also contain highly colored color-bodies associated with cell wall constituents. This color-bodies are based on carotenoids compounds such as a-,~i- and y-carotene and lycopene and xanthophyls, on porphyrins such as chlorophyll and on flavonoid pigments and dye components. This latter group of natural flavonoid based dye components comprises the highly colored anthocyanins ~ 5 dyes and pigments based on peiargonidin, cyanidin, delphidin and their methyl esters and the antoxanthins. These compounds are the origin of most of the orange, red, violet and blue colors occurring in fruits and are abundant in all berries, cherry, red and black currents, grapefruits, passion fruit, oranges, lemons, apples, pears, pomegranate, red cabbage, red beets 2o and also flowers. Derivatives of cyanidin are present in up to 80% of the pigmented leaves, in up to 70% of fruits and in up to 50% of flowers.
The items can be fabrics, hard surfaces, dishware such as plasticware, glassware or chinaware, or teeth and mouth.
It is therefore an object of the present invention to provide a cleaning composition which significantly improves the removal of a broad range of plant based stains. It is another object of the present invention to provide a cleaning composition which enhances fabric realistic items cleaning and 3o whitening.
The above objective has been met by formulating cleaning compositions comprising a xylan degrading alkaline enzyme and bleaching agent.
In a preferred embodiment, the present invention relates to a laundry and/or fabric care composition comprising a xylan degrading alkaline enzyme and a bleaching agent, which enhances fabric realistic items cleaning and whitening. In a second embodiment, the present invention relates to dishwashing or household cleaning compositions comprising a xylan degrading alkaline enzyme and a bleaching agent, and in a third embodiment, the present invention relates to oral/dental care compositions comprising a xylan degrading alkaline enzyme and a bleaching agent.
Xylan degrading enzymes like xylanase are commonly used in the paper/pulp industry and to a lesser extent also in the starch/baking industry.
Examples of such xyian degrading enzymes are the commercial available xylanases e.g. Pulpzyme HB, Pulpzyme HC and SP431 (Novo Nordisk A/S), Lyxasan fGist-Brocades) Optipulp and Xylanase (Solvayl.
In WO 94/01532 is disclosed a method for producing enzymes from ~ 5 strains of the alkalophilic species Bacillus sp. AC13. Enzymes obtainable from these strains are proteases, xylanases and cellulases as well. The protease and cellulase enzymes are demonstrated to be valuable for use in detergents while on the other hand xylanase is shown to be of use in processes for treatment of lignocellulosic pulp i.e. the paper pulp industry.
In WO 92/06209 is disclosed that xylanase enzymes are overexpressed by microbial strains constructed via genetic techniques free of cellulolytic enzymes. These xylanase enzymes are described for use in a variety of applications like the bleaching of wood pulps and the modification of cereals and grains for use in baking and the production of animal feeds.
In WO 92/19726 are disclosed stabilised, modified enzymes. The naturally occurring amino acids (other than proline) have been substituted with a proline residue at one or more positions. Among the modified 3o enzymes, amylases, lipases, cellulases, xylanases and peroxidases are mentioned. Said stabilised, modified enzymes can be used in detergent compositions.
EP 709 452 recognises the benefits for use of xylanase enzymes at low levels in cleaning formulations.

WO 95/35362 describes cleaning compositions containing plant-cell-walls degrading enzymes such as pectinases and/or hemicellulases and/or optionally cellulases. The cleaning properties of the xylanases enzymes were tested in bleach free detergents.
As can be seen from the above, cleaning benefits for the combined use of xylan degrading alkaline enzymes with a bleaching agent have not been previously recognised.
Summary of the invention The present invention relates to cleaning compositions comprising an xylan degrading alkaline enzyme and a bleaching agent, which significantly ~ 5 improve the removal of a broad range of plant based stains.
Detailed description of the invention 2o The xvlan degirading alkaline enzyme An essential component of the detergent compositions of the invention is a xylan degrading alkaline enzyme. The cleaning compositions of the present invention significantly improve the removal of a broad range 25 of plant based stains. In addition, it has been found that the cleaning compositions of the present invention enhance fabric realistic items cleaning and whitening.
Without wishing to be bound by theory, it is believed that the xylan 3o degrading alkaline enzyme is capable of attacking specific parts of piant/fruit cell constituents, breaking them down and facilitating removal during the wash process. This goes by random endo-hydrolysis of the xylan component or by successive exo-hydrolysis of xylose residues from the non-reducing end of the xylan polymer chain or by removal of substituents such 35 as acetyl, 4-O-methyl glucuronic side chains, the L-arabinose side chains and ferulic acid cross linkages and p-coumaric side chains from the xylan polymer of the plant/fruit cells. Moreover, the xyian degrading activity enhances the accessibility of other detergent ingredients at the stain/soil.
Indeed, it is believed that the access for the bleaching agent to the color bodies from the colored plant and/or fruit stains is facilitated by the enzymatic activity of the xylan degrading alkaline enzyme. The discoloration and/or fragmentation of the color bodies in the colored plant and/or fruit constituents and of particulates entrapped in such stains is thereby greatly enhanced.
By xylan degrading enzyme it is meant herein any enzyme which degrade, for instance hydrolyse and/or modify, xylan containing polymers which are associated with hemicellulose and other plant polysaccharides.
By xylan degrading alkaline enzyme it is meant a xylan degrading enzyme having an enzymatic activity of at least 10%, preferably at least 25%, more preferably at least 40% of its maximum activity at a pH ranging ~ 5 from 7 to 12. Preferably, a xylan degrading enzyme having its maximum activity at a pH ranging from 7 to 12.
The xylan degrading alkaline enzyme can be a single xylan degrading activity species or a mixture of the iso-enzymes obtained via the purification 20 of the crude xylan degrading alkaline enzyme mixure. The xylan degrading enzymes of interest are the endo- and exo-Xylanases hydrolysing Xylan in endo- or in exo fashion: endo-1,3 beta Xylosidase (E.C. 3.2.1.32) , the endo-1,4-beta Xylanase (E.C. 3.2.1.8), 1,3-beta D Xylans Xylohydrolase,(E.C. 3.2.1.72), 1,4 -beta D Xylans Xylohydrolase,(E.C.
25 3.2.1.37). Other Xylan degrading alkaline enzymes of interest remove substitutions from the main xylan polymer such as Acetylxylan esterase ;
Glucuronoarabinoxylan endo-1,4-xylanase (E.C. 3.2.1.136), arabinosidase (E.C.3.2.1.55) and ferulic esterase and coumaric acid esterase. These enzymes remove respectively the acetylation , 4-0-methyl glucuronic side 3o chains ; the L-arabinose side chains and ferulic acid cross linkages and p-coumaric side chains from the main xylan polymer.
- The xylan degrading alkaline enzymes can be produced as the wild types by alkalophilic micro-organisms , but also the genes encoding the 35 xylan degrading alkaline enzymes can be cloned and expressed in suitable hosts. The cloned xylan degrading alkaline enzymes are either the natural wild types or the protein engineered enzymes for improved compatibility with detergents. Examples of micro-organisms suitable for the production of the enzymes are listed : Bacillus species: AC13(NCIMB 40482); SD 902 (FERM P-13356); BX-1; BX-2; BX-3; BX-4 ; DSM 71 197; W2 (FERM P-7221 ); W4 (FERM P-7223); C-%(-2 (FERM P-1698); TAR-1; V1-4; 41 M1;
K-12; B. stearothermophilus; B. polymyxa; B. circulars; Thermoto4a species: T. neopolitama; T. thermarium.; Streptomvces species:
S.viridosporus (ATCC 39115) S. olivochromogenes; Asper4illus species: A.
phoenicis; Humicola species: H. insoiens; Trichoderma species: T. reesei (VTT-D-86271-RUT C30); Actinomadura flexuosa; Microtetetraspora to flexuosa ; Thermonaspora fusca KW 3 (DSM 6013); E.coli and variants carrying plasmid pCX31 1; Cepholosporum f NCL 87.1 1.91; Actinomycetes.
Nowadays, it is common practice to modify wild-type enzymes via ~ 5 protein / genetic engineering techniques in order to optimise their performance efficiency in the cleaning compositions of the invention. For example, the variants may be designed such that the compatibility of the enzyme to commonly encountered ingredients of such compositions is increased. Alternatively, the variant may be designed such that the optimal 20 pH, bleach stability, catalytic activity and the like, of the enzyme variant is tailored to suit the particular cleaning application.
In particular, attention should be focused on amino acids sensitive to 25 oxidation in the case of bleach stability and on surface charges for the surfactant compatibility. The isoelectric point of such enzymes may be modified by the substitution of some charged amino acids, e.g. an increase in isoelectric point may help to improve compatibility with anionic surfactants. The stability of the enzymes may be further enhanced by the 30 creation of e.g. additional salt bridges and enforcing calcium binding sites to increase chelant stability.
Pulpzyme HB and Pulpzyme HC from Novo Nordisk and xylanase 35 L120000 from Solvay are commercial available xylan degrading alkaline enzymes.
