Abstract:
A method of laundering fabric materials in a washing machine, comprising the steps of:(a) providing a particulate detergent composition, wherein said particulate detergent composition is a mixture of a spray dried detergent and an agglomeration detergent comprising a perborate component present in a weight ratio in a range of from about 40:60 to about 80:20, spray dried:agglomeration detergent, the final bulk density of said detergent composition being no greater than about 900 g/l; (b) adding a flow aid to said particulate detergent composition in a range from about 0.1% to about 25% by weight of said particulate detergent composition; (c) compacting said particulate detergent composition having said flow aid by applying a pressure in an amount sufficient to form a water-dispersible non-particulate detergent product having a density of at least about 1000 g/l; (d) providing a flexible porous bag adapted for receiving the non-particulate detergent product; (e) placing said non-particulate detergent product within said flexible porous bag; (f) placing said flexible porous bag containing said detergent product in said washing machine with said fabric materials to be washed; wherein the flexible porous bag is adapted for permitting entry of an aqueous washing medium through said bag, thereby dissolving said non-particulate detergent product placed therein, into said aqueous washing medium, and releasing a resultant wash solution from inside of the bag to outside of the bag into said aqueous wash medium during a wash cycle.
