  • 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.
