DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to cleaning compositions, including dishwashing, laundry compositions and oral/dental compositions as well, containing an enzyme with xylanolytic activity. More in particular, the invention relates to compact detergent compositions, granules and liquids as well having said enzyme in the composition.
BACKGROUND OF THE INVENTION
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. Highly coloured or `dried-on` soils derived from fruit and/or vegetables are particularly challenging soils to remove. Specific examples of such soils would include orange, tomato, banana, tea, mango, broccoli soils and grass. Also residues from plants usual contaminating inorganic compounds like mud or clay are very difficult to remove. The substrates can be fabrics, or hard surfaces such as glassware or chinaware.
Xylanolytic 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 xylanolytic enzymes are the commercial available xylanases e.g. Pulpzyme HB and SP431 (Novo Nordisk A/S), Lyxasan (Gist-Brocades) Optipulp and Xylanase (Solvay).
In WO94/01532 is disclosed a method for producing enzymes from 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 WO92/06209 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 WO92/19726 are disclosed stabilized, modified enzymes. The naturally occuring amino acids (other than proline) have been substituted with a proline residue at one or more positions. Among the modified enzymes, amylases, lipases, cellulases, xylanases and peroxidases are mentioned. Said stabilized, modified enzymes can be used in detergent compositions.
However benefits for use of xylanolytic enzymes at low levels in cleaning formulations have not been previously recognized.
SUMMARY OF THE INVENTION
We have now found that xylanolytic enzymes may valuably be incorporated into cleaning compositions at a level of from 0.0001% to 2% of the composition by weight of active enzyme. The inclusion of such enzymes provides stain/soil removal benefits. Removal of food soils/stains, and in particular the removal of dried-on fruit, vegetable soils/stains and/or polysaccharides is enabled. We now have surprisingly found that application of xylanase at above-mentioned levels in cleaning compositions delivers an important boost of the cleaning performance.
It is an object of the present invention to provide cleaning compositions containing enzymes with xylanolytic activity and in particular to provide laundry and dishwashing detergent compositions containing said xylanolytic enzymes providing enhanced soil removal of fruit and/or vegetables stains.
DETAILED DESCRIPTION OF THE INVENTION
An essential component of the cleaning compositions of the invention is a xylanolytic enzyme. This enzyme, preferably xylanase, is 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.
