Abstract: A fabric softening heavy duty liquid detergent composition of controlled viscosity, which does not thicken excessively on aging, 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, low molecular weight polyacrylate and water. Such product is a stable pourable liquid of desired viscosity, density and pH, convenient for use in washing machines, for hand washing of laundry and for pre-treatment of badly soiled portions of items to be laundered. The presence of a small percentage of the polyacrylate in the composition prevents the viscosity thereof from increasing on storage to such an extent as would interfere with pourability.
