Description

A DETERGENT ADDITIVE CONTAINING A CELLULASE AND A PROTEASE
FIELD OF INVENTION
The present invention relates to a detergent additive and detergent composition comprising a cellulase and a protease i the presence of which the cellulase exhibits improved stabilit properties.
BACKGROUND OF THE INVENTION
It has previously been observed that cellulases are sensitiv to the action of proteases, i.e. that in the presence o proteases commonly employed in detergents, cellulases ar degraded to lower molecular weight polypeptides resulting i inactivation of the cellulase enzymes. When cellulases ar employed in liquid detergent compositions, it has typicall been necessary to protect them from proteolytic degradation.
It is therefore an object of the present invention to identif a protease towards which cellulases are less sensitive with view to improving the storage stability of cellulases i detergent additives or detergent compositions containing bot types of enzyme.
SUMMARY OF THE INVENTION
The present invention relates to a detergent additiv comprising a cellulase and a protease, the protease being on which has a higher degree of specificity than Bacillus lentu serine protease.
According to the invention, it has been found that when th protease has such a higher degree of specificity, an increase storage stability of the cellulase is obtained. For the presen purpose, the term "higher degree of specificity" is defined a a protease which conditions degrades human insulin to fewe components than does the B_j_ lentus serine protease under t following conditions: 0.5 ml of a 1 mg/ml solution of hum insulin in B and R buffer, pH 9.5, is incubated with 75 enzyme solution of 0.6 CPU (cf. Novo Nordis Analysis Meth No. AF 228/1) per litre for 120 min. at 37"C, and the reactio is quenched with 50 μl IN HCl.
In another aspect, the present invention relates to a detergen composition comprising a cellulase and a protease as define above.

The detergent composition of the invention additional comprises a surfactant which may be of the anionic, non-ioni cationic, amphoteric, or zwitterionic type as well as mixtur of these surfactant classes. Typical examples of anion surfactants are linear alkyl benzene sulfonates (LAS) , alp olefin sulfonates (AOS) , alcohol ethoxy sulfates (AES) a alkali metal salts of natural fatty acids.
Detergent compositions of the invention may contain oth detergent ingredients known in the art as e.g. builders bleaching agents, bleach activators, anti-corrosion agents sequestering agents, anti soil-redeposition agents, perfumes enzyme stabilizers, etc. The detergent composition of the invention may be formulate in any convenient form, e.g. as a powder or liquid. The enzym may be stabilized in a liquid detergent by inclusion of enzym stabilizers as indicated above. Usually, the pH of a solutio of the detergent composition of the invention will be 7-12 an in some instances 7.0-10.5. Other detergent enzymes such a proteases. Upases or amylases may be included the detergen compositions of the invention, either separately or in combined additive as described above.

The enzyme sample to b determined was dissolved in 0.01 M phosphate buffer, pH 7.5 1.0 ml of the enzyme solution and 2.0 ml of a 0.1 M phosphat buffer, pH 7.5, were mixed in a test tube, and an enzym reaction was initiated by adding 1.0 ml of the substrat solution to the test tube. The mixture was incubated at 40" for 20 minutes, after which the reaction was stopped by addin 2.0 ml of 0.125 M trisodiu phosphate.12H20. A blind sample wa prepared without incubation.
2.0 ml of a ferricyanide solution (1.60 g of potassiu ferricyanide and 14.0 g of trisodium phosphate.12H20 in 11 o deionized water) was added to a test sample as well as to blind immediately followed by immersion in boiling water an incubation for 10 minutes. After incubation, the samples wer cooled with tap water. The absorbance at 420 n was measured and a standard curve was prepared with glucose solution.
One CMCase unit (CMCU) is defined as the amount of enzym which, under the conditions specified above, forms an amoun of reducing carbohydrates corresponding to 1 μmol of glucos per minute.
Results
The storage stability of the endoglucanase of the invention was determined as its residual activity (in CMCU%) under the conditions indicated above.
