ABSTRACT A process is disclosed for preparing a toilet bar composition whose components comprise a fatty acid soap and a C10-C16 acyl isethionate salt in the ratio of about 20:1 to 1:0.98, respectively. The blend is charged with an initial amount of water from 12 to 30% by weight of the composition. Heating and mixing are terminated after the blend has passed a second peak in viscosity, termination occurring between about 500 and 6,000 centipoise at 35 sec-1 shear rate at 99-103°C (210-218°F). The final moisture content of the blend must be between 8.5 to 20% water.
