Definitions
- the present invention relates to the use of cellulase to enhance the cleaning performance of detergents against starchy soiling.
- Enzymes especially proteases and lipases, but also amylases and cellulases, are used extensively in washing, auxiliary washing and cleaning agents.
- Proteases, lipases and amylases are primarily used to remove protein, fat and starch stains.
- cellulases have a special position because they are not used to remove special stains, but because of their ability to break down cellulose, have long been known as anti-aging agents for cotton fabrics.
- a side effect of the breakdown of cellulose fibrils by cellulases is the deepening of the optical color impression, the so-called color refreshment, which results from the treatment of colored cotton textiles with cellulases when the undyed fibrils resulting from fiber damage and originating from the interior of the fiber are removed.
- the enzymes mentioned are not only used individually, but usually in combinations with one another.
- a detergent is known from European patent application EP 0 755 999 A1 which contains a stability-improved amylase in combination with protease, it being possible for further enzymes such as lipase and cellulase to be present.
- the international patent application WO 94/24258 AI relates to enzyme-containing detergents which contain protease, lipase, amylase and cellulase and not more than 10% by weight of surfactant and / or not more than 40% by weight of builder.
- European detergents EP 0 425 214 A2 disclose detergents which, in addition to surfactants and builders, contain protease and amylase and a third enzyme selected from lipase and cellulase.
- European patent application EP 0 365 103 A2 relates to detergents, the 4-30% by weight nonionic surfactant, 25-80% by weight builder, 1-15% by weight water and 0.1-2% by weight protease , 0.2-1 wt .-% cellulase and up to 2 wt .-% amylase.
- the problem with polysaccharide soiling is that naturally occurring polysaccharides, such as those found in foods, do not normally consist exclusively of starch, but also contain other or otherwise linked saccharides.
- ⁇ -amylases intended for use in detergents are generally well suited to hydrolyzing the starch content of polysaccharide stains in water-soluble oligosaccharides, their dirt removal ability can be felt to be in need of improvement if they are stains from other polysaccharides or these make up larger parts of the polysaccharide stains.
- the applicant had set itself the goal of remedying this situation and improving the cleaning performance of detergents compared to polysaccharide stains.

- Brighteners of the substituted diphenylstyryl type may also be present, for example the alkali salts of 4,4'-bis (2-sulfostyryl) diphenyl, 4,4'-bis (4-chloro-3-sulfostyryl) diphenyl, or 4 - (4-chlorostyryl) -4 '- (2-sulfostyryl) diphenyl. Mixtures of the aforementioned optical brighteners can also be used.
- Suitable foam inhibitors are, for example, soaps of natural or synthetic origin, which have a high proportion of C 8 -C 24 fatty acids.
- Suitable non-surfactant-like foam inhibitors are, for example, organopolysiloxanes and their mixtures with microfine, optionally silanized silica, and also paraffins, waxes, microcrystalline waxes and their mixtures with silanized silica or bisfatty acid alkyl diamides. Mixtures of different foam inhibitors are also used with advantages, for example those made of silicone, paraffins or waxes.
- the foam inhibitors in particular silicone and / or paraffin-containing foam inhibitors, are preferably bound to a granular, water-soluble or dispersible carrier substance. Mixtures of paraffins and bistearylethylenediamide are particularly preferred.
- the preparation of solid agents of the type described above presents no difficulties and can be carried out in a known manner, for example by spray drying or granulation, the cellulase and, if appropriate, further enzymes and any other thermally sensitive ingredients, such as bleaching agents, optionally being added separately later.
- a process known from European patent EP 0486 592 and having an extrusion step is preferred.
- Liquid or pasty detergents in the form of solutions containing customary solvents are generally prepared by simply mixing the ingredients, which can be added in bulk or as a solution to an automatic mixer.
- cotton fabric soiled with standardized test soiling (oatmeal / cocoa) was washed at 40 ° C (detergent dosage 76 g; water hardness 16 ° d; load 3.5 kg, short program) in a household washing machine (AEG ⁇ ko Lavamat® 694) washed.
- Table 1 below shows the washing results (in dE initial value minus dE after washing, measuring device Minolta® CR 310) for a cellulase- and amylase-free detergent VI, for a cellulase-free detergent V2 (containing 0.6% by weight of the amylase granulate Termamyl ® 60T; manufacturer Novo Nordisk) and for agents Ml to M5 reinforced according to the invention in their cleaning performance, which were otherwise composed like V2, but with 0.2% by weight, 0.4% by weight, 0.6% by weight. -%, 0.8% by weight or 1.0% by weight Celluzyme® 0.7T (manufacturer Novo Nordisk) had been added, as the result of duplicate determinations.
- Example 1 was repeated, in the compositions with additives used according to the invention (M6 to MIO) instead of Celluzyme®, activity-equivalent amounts of KAC® 500 (manufacturer Kao) were used. From the washing results given in Table 2, one can also see here the superiority of the cleaning performance of the agents according to the invention.
- Example 1 was repeated, in the compositions with additives used according to the invention (Mll to M15) instead of Celluzyme®, activity-equivalent amounts of cellulase BCE 103 (as described in WO 96/34108) were used and the washing tests were carried out under otherwise identical conditions in one Washing machine Miele® W918. From the washing results given in Table 3, the superiority of the cleaning performance of the agents according to the invention can also be seen here. Table 3: Washing results (dE AW - dE washed)
