BLEACH-CONTAINING NON-AQUEOUS DETERGENT FORMULATED TO CONTROL DYE TRANSFER AND SUDSING IN HIGH EFFICIENCY WASHING MACHINES

摘要

Disclosed is a method of laundering soiled fabrics comprising the steps of contacting said fabric in an aqueous laundering solution with a nonaqueous liquid detergent composition containing from about 40 % to about 99 % by weight of the composition of a surfactant- containing non-aqueous liquid phase and from about 1 % to about 50 % by weight of the composition of particulate material which is substantially insoluble in said liquid phase a nd which is selected from peroxygen bleaching agents, bleach activators, organic detergent builders, inorganic alkalinity sources and combinations thereof. A dye transfer inhibitor and suds suppressors are essential components in one aspect of the present invention. The detergent composition is added to the aqueous solution in a washing machine at a concentration in the aqueous solution of from 2000 ppm to about 10,000 ppm, wherein from about 3 gallons to about 8 gallons of water is used to form the aqueous solution, said fabric to water weight ratio is from about 1 :1 to about 1:9 and said fabrics undergo a wash time of from about 8 minutes to about 16 minutes .
