    • The cleaning performance of bleach-containing detergents, especially against protein- and starch-containing soils and colored soils, was to be improved. This was essentially achieved through the presence in the detergent—besides typical ingredients compatible with such components—of a compound corresponding to general formula I: in which R1 represents —H, —CH3, a C2-24 alkyl or alkenyl group, a substituted C2-24 alkyl or alkenyl group with at least one substituent from the group consisting of —Cl, —Br, —OH, —NH2, —CN, an alkyl or alkenyl aryl group containing a C1-24 alkyl group or a substituted alkyl or alkenyl aryl group containing a C1-24 alkyl group and at least one other substituent at the aromatic ring, R2 ad R3 independently of one another are selected from —CH2—CN, —CH3, —CH2—CH3, —CH2—CH2—CH3, —CH(CH3)—CH3, —CH2—OH, —CH2—CH2—OH, —CH(OH)—CH3, —CH2—CH2—CH2—OH, —CH2—CH(OH)—CH3, —CH(OH)—CH2—CH3, —(CH2CH2—O)nH where n=1, 2, 3, 4, 5 or 6 and X is an anion, and an enzyme selected from the group consisting of protease, amylase, lipase, cellulase and mixtures thereof.

    • The invention relates to sodium silicates with a modulus (molar ratio of SiO.sub.2 to Na.sub.2 O) of 1.3 to 4 in the form of a fine-particle solid in shard-like form or compounds containing these silicates with the ability to reduce incrustation when used as a builder component in detergents. These useful materials are distinguished in particular by the fact that they are in the form of an X-ray amorphous overdried material (primary drying product) with water contents below 15% by weight and apparent densities of the non-compacted solid granules of 500 g/l or lower which has been produced by drying of a water-containing sodium silicate preparation using a hot gas phase as the drying medium and/or by heating of a spray-dried sodium silicate with water contents of at least 15% by weight at temperatures of 120.degree.to 450.degree. C., if necessary accompanied or followed by the application of forces to produce the shard-like structure. The invention also relates to multicomponent mixtures from the field of solid detergents or multicomponent compounds suitable for this field of application which are characterized by the presence of the sodium silicates defined above.
