ABSTRACT:
A fabric softening heavy duty liquid detergent, useful for both cleaning and softening laundry, includes certain proportions of sodium linear higher alkylbenzene sulfonate, sodium alkyl polyethoxy sulfate, builder salt (highly preferably a mixture of sodium tripolyphosphate and sodium carbonate), finely divided swelling bentonite and water. Such product is a stable pourable liquid, convenient for use in washing machines, for hand washing of laundry and for pre-treatment of badly soiled portions of items to be laundered. Preferably, the liquid detergent comprises about 9% of sodium linear tridecylbenzene sulfonate, about 2% of sodium alkyl polyethoxy sulfate wherein the alkyl is of 12 to 15 carbon atoms and the polyethoxy is of 3 ethylene oxide groups, 10 to 17% of sodium tripolyphosphate, e.g., 12% and 15%, 2 to 6% of sodium carbonate, e.g., 2% and 6%, about 12% of Wyoming bentonite, and 55 to 65% of water. Also within the invention is a process for manufacturing such liquid detergent wherein the swelling bentonite is admixed with a mixture of the other detergent composition components except for part of the water, which is added last to the mixture of such components and the bentonite.
