ABSTRACT:
A process is disclosed for preparing a toilet bar composition whose components comprise a fatty acid soap and a C.sub.10 -C.sub.16 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.sup.-1 shear rate at 210.degree.-218.degree. F. The final moisture content of the blend must be between 8.5 to 20% water.
