  • Powder detergent process
    Patent number: 6458756
    Abstract: A process for applying relatively volatile ingredients, such as perfume, to powdered detergents minimizes the loss of the ingredients to the atmosphere and increases plant efficiency.
    Type: Grant
    Filed: June 14, 2000
    Date of Patent: October 1, 2002
    Assignee: Unilever Home & Personal Care USA division of Conopco, Inc.

  • Preparation of bleach catalyst aggregates of manganese cation impregnated aluminosilicates by high velocity granulation
    Patent number: 4711748
    Abstract: A process is disclosed for the preparation of bleach catalysts in aggregate form. The steps comprise adsorbing a manganese (II) salt onto an aluminosilicate support; granulating with a high disrupting force an aqueous slurry of the aluminosilicate bearing manganese (II), and drying the resultant aggregates. At least 70% of the dried aggregates resulting from the process must have a diameter size from at least 250 to about 2000 microns.
    Type: Grant

    Date of Patent: December 8, 1987
    Assignee: Lever Brothers Company
    Inventors: Charles F. Irwin, William Karpusiewicz, Patricia Liberati
  • Bleach composition of detergent base powder and agglomerated manganese-alluminosilicate catalyst having phosphate salt distributed therebetween
    Patent number: 4655782
    Abstract: A bleaching composition is disclosed wherein the bleach catalyst is an aggregate comprising manganese (II) cations adsorbed onto an aluminosilicate support, a binder and a phosphate salt; the aggregates have a diameter ranging from at least 250 to about 2000 microns which aggregates upon dispersion in water for two minutes at pH 10 and 40.degree. C. leave undissolved less than 5% particles of 125 microns or higher. The base detergent powder comprises a phosphate salt and a peroxy compound. It was found that bleach performance improves by having phosphate salt both in the aggregate and in the detergent powder base.
