- 8. The process of claim 1 wherein the water-dispersible non-particulate detergent product has at least about 25% greater dispersability in water as compared to a non-particulate detergent product having a density of at least about 1000 g/l and having the flow aid in an amount less than about 2% by weight of the particulate detergent composition.
- 9. The process of claim 1 wherein the water-dispersible non-particulate detergent product has at least about 50% greater dispersability in water as compared to a non-particulate detergent product having a density of at least about 1000 g/l and having the flow aid in an amount less than about 5% by weight of the particulate detergent composition.
- 10. The process of claim 1 wherein the flow aid is in the form of porous carrier particles.
- 11. The process of claim 10 wherein the 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, carboxylalkylstarches, cyclodextrins, porous starches and mixtures thereof.
- 12. The process of claim 10 wherein the porous carrier particles are selected from the group consisting of Zeolite A, Zeolite X, Zeolite Y, Zeolite P, Zeolite MAP and mixtures thereof.
- 13. The process of claim 1 wherein the step of providing a particulate detergent composition includes providing the detergent composition having a bulk density of no greater than about 900 g/l.
- 14. The process of claim 1 wherein the step of providing a particulate detergent composition includes providing the detergent composition having a bulk density in the range of from about 600 g/l to about 850 g/l.
- 15. The process of claim 14 wherein the step of providing a particulate detergent composition includes providing the detergent composition having a bulk density in the range of from about 625 g/l to about 725 g/l.
- 16. The process of claim 1 wherein the water-dispersible non-particulate detergent product has at least about 10% greater dispersibility in water as compared to a non-particulate detergent product having a density of at least about 1000 g/l and formed from a particulate detergent composition having a bulk density no greater than 700 g/l, when the flow aid is added in an amount greater than about 1% by weight of the particulate detergent composition and when the particulate detergent composition has a bulk density no greater than 700 g/l.
- 17. The process of claim 1 wherein the flow aid is in the form of a powder homogeneously mixed in the particulate detergent composition.
- 18. The process of claim 17 wherein the flow aid substantially covers the surface of the particulate detergent composition.
- 19. A method of laundering fabric materials in a washing machine, comprising the steps of:
a) providing a flexible porous bag adapted for receiving a non-particulate detergent product; b) providing a non-particulate detergent product; c) placing the non-particulate detergent product within the flexible porous bag; and d) placing the flexible porous bag containing the detergent product in the washing machine with the fabric materials to be washed; wherein the flexible porous bag is adapted for permitting entry of an aqueous washing medium through the bag, thereby dissolving the non-particulate detergent product placed therein, into the aqueous washing medium, and releasing a resultant wash solution from inside of the bag to outside of the bag into the aqueous wash medium during a wash cycle.
- 20. The method of claim 19 wherein the particulate detergent product has a density of at least 1000 g/l.
- 21. A method of laundering soiled clothes comprising the step of immersing the soiled clothes in an aqueous solution medium containing an effective amount of a non-particulate detergent product made by a process according to claim 1.
- 22. A water-dispersible non-particulate detergent product, comprising: a core formed by compacting a particulate detergent composition to a density of at least about 1000 g/l, the particulate detergent composition having a bulk density in a range of from about 600 g/l to about 850 g/l, and the particulate detergent composition comprising a flow aid in a range of from about 0.1% to about 25% by weight of the particulate detergent composition.
- 23. The water-dispersible non-particulate detergent product of claim 22 wherein the water-dispersible non-particulate detergent product has at least about 5% greater dispersibilty in water as compared to another non-particulate detergent product having a density of at least about 1000 g/l but not having the flow aid.
