• a lipase is an enzyme that catalyzes the hydrolysis of ester bonds in lipid substrates, especially in fats and oils. Lipases are therefore a subset of esterases. Lipases are generally versatile enzymes that accept a variety of substrates, for example, aliphatic, alicyclic, bicyclic and aromatic esters, thioesters and activated amines. Lipases act against fat residues in the laundry by catalyzing their hydrolysis (lipolysis). Lipases with broad substrate spectra are used in particular where inhomogeneous raw materials or substrate mixtures have to be reacted, for example in detergents and cleaning agents, since soiling usually consists of differently structured fats and oils.

• Further antifoams are paraffin hydrocarbons, in particular microparaffins and paraffin waxes whose melting point is above 40 ° C., saturated fatty acids or soaps having in particular 20 to 22 carbon atoms, for example sodium behenate, and alkali metal salts of phosphoric mono- and / or dialkyl esters in which the alkyl chains each having 12 to 22 carbon atoms.
• the proportion of foam regulators may preferably be from 0.2% by weight to 2% by weight.

• organic solvents which can be used in the compositions, in particular if they are in liquid or pasty form, are alcohols having 1 to 4 C atoms, in particular methanol, ethanol, isopropanol and tert-butanol, diols having 2 to 4 C atoms, in particular ethylene glycol and propylene glycol, and mixtures thereof and the derivable from said classes of compounds ethers.
• Such water-miscible solvents are present in the compositions in amounts of preferably not more than 20% by weight, in particular from 1% by weight to 15% by weight.
• the agents can system and environmentally acceptable acids, in particular citric acid, acetic acid, tartaric acid, malic acid, lactic acid, glycolic acid, succinic acid, glutaric acid and / or adipic acid, but also, mineral acids, in particular sulfuric acid or alkali metal hydrogen sulfates, or bases, in particular ammonium or alkali metal hydroxides.
• Such pH regulators are preferably not more than 10 wt .-%, in particular from 0.5 wt .-% to 6 wt .-%, included.
• compositions presents no difficulties and can be carried out in a manner known in the art, for example by spray-drying or granulation, thermally-sensitive ingredients optionally being added separately later.
• compositions in the form of aqueous or other conventional solvent-containing solutions are particularly advantageously prepared by simply mixing the ingredients, which can be added in bulk or as a solution in an automatic mixer.
• compositions are preferably in the form of pulverulent, granular or tablet-like preparations which are prepared in a manner known per se, for example by mixing, granulating, roll compacting and / or spray-drying the thermally stable components and admixing the more sensitive components, in particular enzymes, bleaches and bleach-activating agents Active ingredients are expected to be produced.
• a process comprising an extrusion step is preferred.
• a tablet thus produced has a weight of 15 g to 40 g, in particular from 20 g to 30 g, with a diameter of 35 mm to 40 mm.

• V2 had a higher washing performance on 4 soiling and was the same for 86 soiling within the scope of the measuring accuracy (here and below: 6-fold determination).
• V3 had a higher washing performance on 21 stains and was equal to 69 soiling within the scope of the measuring accuracy.
• E1 had a higher washing performance on 27 soilings and was equal to 63 soiling within the scope of the measuring accuracy.
• the simultaneous use of both ingredients surprisingly showed a greater number of advantages (27) than the sum of the individually used ingredients (21 + 4).
• the superiority of E1 was particularly pronounced in the stains blood / milk / ink and olive oil / soot.
