  • Patent number: 6638320
    Abstract: A method of laundering fabric materials in a washing machine includes the steps of providing a non-particulate detergent product comprising a mixture of spray-dried detergent and an agglomeration detergent comprising a perborate component, and a flow aid; providing a flexible porous bag for receiving the non-particulate detergent product; placing the non-particulate detergent product within the flexible porous bag containing the detergent product in the washing machine with the fabric materials to be washed.

  • Publication number: 20030060394
    Abstract: A process for producing a water-dispersible non-particulate detergent product includes the step of providing a particulate detergent composition. The process further includes the step of adding a flow aid to the particulate detergent composition in a range of from about 0.1% to about 25% by weight of the particulate detergent composition. The process then includes the step of compacting the particulate detergent composition having the flow aid by applying a pressure in an amount sufficient to form the water-dispersible non-particulate detergent product having a density of at least about 1000 g/l. This process enables the manufacture of a rapidly dispersing non-particulate detergent composition that sinks in water.

  • Patent number: 6498135
    Abstract: A process for producing a non-particulate laundry detergent comprises the steps of providing a powdered porous carrier material, adsorbing a perfume onto the powdered porous carrier material, and depositing the powdered porous carrier material having adsorbed perfume on the non-particulate detergent product. In another aspect of the invention, a process for producing a non-particulate detergent product having a perfume loaded carrier material coating includes the step of providing a non-particulate detergent composition having an electrically conductive surface. The process further includes grounding the electrically conductive surface of the non-particulate detergent composition. Still further, the process includes providing an electrostatically chargeable carrier material having a perfume adsorbed therein.

  • Patent number: 6492319
    Abstract: A process for producing high density detergent compositions is provided. The process is a continuous process during which high density detergent agglomerates are produced by feeding a surfactant paste and dry starting detergent material into a moderate speed mixer/densifier having a centrally positioned rotating shaft and at least one high speed chopper. The surfactant paste is inputted at least one location along the length of the moderate speed mixer/densifier to achieve optimal build-up agglomeration. The proces produces a free flowing, high density detergent composition which can be commercially sold as a low dosage or “compact” detergent composition.

  • Patent number: 6358902
    Abstract: A detergent tablet which contains a bleach activator is disclosed. The bleach activator is in particulate form and has a particle size in a range of from about 100 microns to about 4000 microns. The bleach activator is present in a range of from about 0.1% to about 15% by weight of the detergent tablet.

  • Patent number: 6133224
    Abstract: Process for making a free-flowing, particulate dye transfer inhibiting detergent admix for inclusion in a granular laundry detergent composition consisting essentially of the steps of: charging from 50% to 95%, by weight of the dye transfer inhibiting detergent admix, of a detergent builder into a mixer/granulator; adding to the detergent builder from 5% to 50%, by weight of the dye transfer inhibiting detergent admix, of a dye transfer inhibitor solution to thereby form a mixture; and agglomerating the mixture of the dye transfer inhibitor solution and the detergent builder so as to form the dye transfer inhibiting detergent admix.

  • Patent number: 5891838
    Abstract: A bleach-containing detergent composition which contains a peroxygen bleaching compound and a bleach activator is disclosed. The bleach activator is in the form of particles having a mean particle diameter of 200 microns to 2000 microns. Also disclosed are bleach activator particles in the form of substantially cylindrically-shaped extrudates having a mean extrudate length of from about 500 microns to about 3500 microns and a mean extrudate diameter of from about 450 microns to about 850 microns.

  • Patent number: 5712242
    Abstract: A free-flowing granular detergent component or composition having a bulk density of at least 650 g/l comprises (i) at least 35% by weight of anionic surfactant; (ii) 0.5% to 10% by weight of a chelating agent; (iii) 0.5% to 30% by weight of a polymer or co-polymer wherein the weight ratio of chelating agent to polymer/copolymer is from 1:100 to 1:1. Additionally, processes for making the granular detergent component or composition comprise adding aqueous solutions of a chelating agent and a polymer or copolymer to a high active surfactant paste.
