Abstract:
A method of laundering soiled fabrics in a high efficiency automatic washing machine, which method comprises the steps of:a) forming an aqueous laundering solution in said washing machine, said solution containing from about 2000 ppm to about 10,000 ppm of a non aqueous liquid detergent composition in from about 3 gallons to about 8 gallons of water; b) adding soiled fabrics to said aqueous solution such that the weight ratio of fabric to laundering solution ranges from about 1:1 to 1:10; and c) washing said fabrics in said solution for a period of time ranging from about 6 to 34 minutes; wherein said nonaqueous liquid detergent composition contains:i) from about 40% to about 99% by weight of the composition of a surfactant-containing non-aqueous liquid phase; ii) from about 1% to about 50% by weight of the composition of a particulate material which is substantially insoluble in said liquid phase and which comprises materials selected from the group consisting of peroxygen bleaching agents, bleach activators, organic detergent builders, inorganic alkalinity sources and combinations thereof; iii) an effective amount of a dye transfer inhibitor; and iv) an effective amount of a suds suppressor.
