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. Finally, the process includes coating the electrostatically chargeable carrier material onto the electrically conductive surface of the non-particulate detergent composition by means of an electrostatic charging and delivery system, whereby the electrostatically charged carrier material is adhered to the electrically conductive surface of the detergent composition.
