Abstract: The invention relates to a process for the production of substantially alumosilicate-free detergents containing a soluble builder system which provides free-flowing and storage-stable granules. In this process for the production of a particulate, substantially alumosilicate-free detergent, an anionic surfactant acid is sprayed onto a detergent component containing anionic surfactant and builders in order to increase the anionic surfactant content.

Abstract: A bleaching composition is presented having a) an enzyme which produces hydrogen peroxide from atmospheric oxygen, b) a substrate for said enzyme, and c) a transition metal compound, where the enzyme is covalently bound to the transition metal compound. The bleaching composition is useful in disinfectants and laundry detergents as a bleaching component and for inhibiting the transfer of dyes.

Abstract: The problem addressed by the invention was to provide a foam regulator system containing silicone and/or paraffin and bis-fatty acid amide which would have a low viscosity, which could be handled at low temperatures and which would have a low percentage content of non-foam-regulating ingredients. This problem was largely solved by an aqueous foam regulator emulsion containing 16% by weight to 70% by weight of active foam regulator based on paraffin wax and/or silicone oil, 2% by weight to 15% by weight of nonionic and/or anionic emulsifier and no more than 80% by weight of water. The foam regulator emulsion is preferably used for the production of partiulate foam regulator granules for use in detergents.

Abstract: A process for producing pourable foam regulator granules containing a defoamer combination of a paraffin wax and a bisamide derived from diamines and carboxylic acids and an inorganic, water-soluble or water-dispersible carrier salt by pelletizing in a granulation mixer with intensive mixing 50 to 100 parts by weight of the inorganic carrier salt optionally with up to 5 parts by weight of an anionic or nonionic cellulose ether, adding 1 to 10 parts by weight of an aqueous alkali metal silicate or polymeric polycarboxylate solution and then adding 10 parts by weight of the defoamer combination heated to a temperature of 70° C. to 180° C.

Abstract: The invention relates to a process for regenerating wastepaper and to the use of certain hydroxysulfonate salts for removing printing ink from printed wastepaper and/or paper circuit waters.

Abstract: In a process for processing waste paper, aqueous suspensions of pulp are treated with cationic layer compounds precipitated in situ. The separated printing inks, fillers and/or unwanted substances are then removed from the fibrous suspensions in a known manner by flotation or washing out.

Abstract: The use of mixed hydroxyethers of the general formula IR.sup.1 O--(CH.sub.2 CH.sub.2 O).sub.x --CH.sub.2 --CH(OH)R.sup.2 (I)in whichR.sup.1 denotes an alkyl group having 1 to 10 carbon atomsR.sup.2 denotes an alkyl group having 8 to 20 carbon atoms and x denotes a number in the range from 1 to 20 as auxiliaries for the dehydration of water-containing finely divided solids, gives solids having a low water content without foaming in the water separated therefrom.
