  • Agglomerated colorant speckle exhibiting reduced colorant spotting
    Patent number: 5605883
    Abstract: The present invention is a granular colorant speckle exhibiting reduced colorant spotting, the speckle which comprises:(a) an insoluble dispersible carrier;(b) a surfactant; and(c) a substantive agent.The present invention also discloses a method for forming a colorant speckle suitable for use as a granular laundry detergent component, or a laundry additive. The speckle of the present invention is preferably produced by an agglomeration process utilizing, for example, a fluid-bed or rotary falling curtain type agglomerator.
    Type: Grant

  • Zeolite agglomeration process and product
    Patent number: 5205958
    Abstract: The present invention relates to a zeolite agglomeration process and product. Zeolite particles are blended with a filler and preferably a surfactant and then agglomerated in a rotary agglomerator with a zeolite binder to form an agglomerate with about 5-70 parts by wgt. zeolite and, after drying, excellent mechanical strength and flowability with good solubilization/dispersion in aqueous solution. The zeolite agglomerate is preferably combined into a granular detergent in a second agglomeration step where the zeolite agglomerate is combined with other detergent components and sprayed with a detergent binder, the granular detergent being characterized by uniform density and particle size with minimum segregation and dusting. Both the zeolite agglomeration and detergent agglomeration steps are characterized by energy efficiency.
