  • Patent number: 4851137
    Abstract: Bentonite agglomerates are made which are suitable for use as a particulate fabric softener for softening washed laundry, especially when incorporated in detergent compositions by mixing with spray dried beads containing essential detergent composition components. Such agglomerates are in the Nos. 10-100 sieve range and are agglomerates of finely divided bentonite. The agglomerates are of a bulk density in the range of 0.7 to 0.9 g./ml., a moisture content of 8 to 13% and a frangibility less than 30, and include 1 to 5% of a binder (sodium silicate). Also disclosed is a method for making the bentonite agglomerates by spraying an aqueous solution of the binder onto moving surfaces of finely divided bentonite until the moisture content thereof is elevated and the amount of binder for the agglomerate is sufficient, and drying the agglomerated particles to their "equilibrium moisture range".
    Type: Grant

  • Patent number: 4767546
    Abstract: Bentonite agglomerates are made which are suitable for use as a particulate fabric softener for softening washed laundry, especially when incorporated in detergent compositions by mixing with spray dried beads containing essential detergent composition components. Such agglomerates are in the Nos. 10-100 sieve range and are agglomerates of finely divided bentonite. The agglomerates are of a bulk density in the range of 7.0 to 0.9 g./ml., a moisture content of 8 to 13% and a frangibility less than 30, and includes 1 to 5% of a binder (sodium silicate). Also disclosed is a method for making the bentonite agglomerates by spraying an aqueous solution of the binder onto moving surfaces of finely divided bentonite until the moisture content thereof is elevated and the amount of binder for the agglomerate is sufficient, and drying the agglomerated particles to their "equilibrium moisture range".
