1. A rheological solid composition comprising:
a crystallizing agent; an aqueous phase comprising at least about 80 wt % water; and NaCl;
wherein, the rheological solid composition has a firmness between about 1.0 N to about 20.0 N as determined by the FIRMNESS TEST METHOD using a texture analyzer at room temperature;
a thermal stability of about 40° C. to about 95° C. as determined by the THERMAL STABILITY TEST METHOD using a differential scanning calorimeter (DSC);
a liquid expression of between about 100 J m-3 to about 8,000 J m-3 as determined by the AQUEOUS PHASE EXPRESSION TEST METHOD using a rheometer at room temperature; and
wherein the crystallizing agent is a blend of sodium salts of fatty acids containing from 13 to 17 carbon atoms; wherein the crystallizing agent blend has an Optimal Purity (Po) of greater than about 0.3 and a Single Purity (Ps) of greater than about 0.5 as determined by the BLEND TEST METHOD;
wherein the amount of crystallizing agent in the composition is between about 0.5% and 7.0% by weight of the rheological solid composition.
