ABSTRACT:
The present invention relates to a process for the preparation of foam-controlled pulverulent detergents. In this process (a) 80 to 99.9 parts by weight of a pulverulent, water-soluble, non-surfactant constituent of the detergent are mixed homogeneously with (b) 0.1 to 20 parts by weight of silicone oil or silicone oil/silica mixtures, which are homogeneously dispersed or dissolved in a solvent, the solvent is then removed and the residue is mixed with further constituents necessary for the preparation of a detergent.
If desired, the detergent can also be treated as a whole with component (b). The process enables the detergents (washing powders) of any desired foam capacity to be prepared.
