  • Patent number: 6482876
    Abstract: The invention relates to an agglomerate containing at least one of the following water-soluble or water-dispersible materials as a bonding base polymer: carboxylized and/or alkoxylized starch, cellulose ether and fully synthetic vinyl polymers and/or polyacrylates. The agglomerate is characterized in that it contains a blasting agent which produces a high swelling pressure, but, advantageously, does not gel. The agglomerate can have a regular geometric form or not. Its weight should be between 0.5 and 500 g. The agglomerate is used in particular in the production of lump-free paste.

  • Patent number: 6211136
    Abstract: A process for the production of pourable and free-flowing granular detergent composition components containing an active substance at least partly liquid at room temperature and a fine-particle carrier material for that active substance wherein the carrier material has a mean particle size of 3 &mgr;m to 0.5 mm by dropping the carrier material onto a rotating disk where it is radially accelerated by vanes arranged on the upper surface of said disk, and applying the liquid active substance to a stream of the carrier particles through an annular die formed by the outer edge of the rotating disk and a stator surrounding the disk.

  • Patent number: 5780420
    Abstract: 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 C., if necessary accompanied or followed by the application of forces to produce the shard-like structure.

  • Patent number: 5318718
    Abstract: A process for the production of pourable foam inhibitor granules comprising forming an aqueous solution of a mixture of an alkali metal carboxymethyl cellulose and a nonionic cellulose ether and maintaining the aqueous solution at slightly elevated temperature until the viscosity is at least 60% of the viscosity obtained by complete swelling of the solution, adding a water insoluble foam inhibitor and a phosphate-free mixture of at least two of an alkali metal silicate, an alkali metal carbonate and an alkali metal sulfate into the aqueous mixture which is then spray-dried to form the pourable foam inhibitor granules.The invention also relates to the pourable foam inhibitor granules produced by the above process.
