Claims
- 1. A process for producing a non-particulate detergent product having a perfume loaded carrier material coating, comprising the steps of:(a) providing a non-particulate detergent composition having an electrically conductive surface; (b) grounding said electrically conductive surface of said non-particulate detergent composition; (c) providing an electrostatically chargeable carrier material having a perfume adsorbed therein; (d) coating said electrostatically chargeable carrier material onto said electrically conductive surface of said non-particulate detergent composition by means of applying an electrostatic charge with an electrostatic charging and delivery system, such that said electrostatically charged carrier material is adhered to said electrically conductive surface of said detergent composition, even after dissipation of said electrostatic charge.
- 2. The process of claim 1 wherein said electrically conductive surface is formed of a coating comprising a material which is insoluble in water at 25 degrees C.
- 3. The process of claim 1 wherein said electrically conductive surface is formed of a coating comprising a water-insoluble material having a melting point in the range of about 40 degrees C. to about 180 degrees C.
- 4. The process of claim 1 wherein said electrically conductive surface is formed of a coating selected from the group consisting of C12-C22 fatty acids, adipic acid, C8-C13 dicarboxylic acids, or mixtures thereof.
- 5. The process of claim 1 wherein said electrically conductive surface is formed of a coating selected from the group consisting of C12-C22 fatty alcohols.
- 6. The process of claim 1 wherein said electrostatically chargeable carrier material is in the form of porous carrier particles.
- 7. The process of claim 6 wherein said porous carrier particles are selected from the group consisting of amorphous silicates, crystalline nonlayered silicates, layered silicates, calcium carbonates, calcium/sodium carbonate double salts, sodium carbonates, clays, zeolites, sodalites, alkali metal phosphates, macroporous zeolites, chitin microbeads, carboxyalkylcelluloses, carboxyalkylstarches, cyclodextrins, porous starches and mixtures thereof.
- 8. The process of claim 6 wherein said porous carrier particles are selected from the group consisting of Zeolite A, Zeolite X, Zeolite Y, Zeolite P, Zeolite MAP and mixtures thereof.
- 9. The process of claim 1 wherein said electrostatic charging and delivery system is an electrostatic powder spray gun.
- 10. The process of claim 9 wherein said electrostatically chargeable carrier material is provided to said spray gun in the form of finely divided particles which are electrostatically charged by said spray gun and then sprayed onto said electrically conductive surface of said non-particulate detergent composition.
- 11. The process of claim 1 wherein said electrostatically chargeable carrier material is in the form of particles having a mean diameter less than 25 microns.
- 12. The process of claim 1 wherein said electrostatic charging and delivery system is an electrostatic fluidized bed chamber.
- 13. The process of claim 12 wherein said perfume loaded carrier material is in the form of finely divided particles suspended in said fluidized bed chamber and electrostatically charged by ionized air passing through said chamber, and said non-particulate detergent composition is placed in said bed chamber and in contact with a grounding source.
