1. A rheological solid oral composition for delivering an oral active agent, comprising:
a crystallizing agent comprising a blend of salts of fatty acids containing from 13 to 16 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;
an aqueous phase comprising water and a solvent; and
an oral active agent;
wherein the rheological solid composition comprises from about 80% to about 99.5% water and about 0.5% to about 15% solvent, by weight of the rheological solid oral composition;
wherein the rheological solid oral composition has a crystalline mesh comprising a rigid,
three-dimensional, interlocking crystalline skeleton framework of fiber-like crystalline particles formed from crystallizing agents, and the framework has voids or openings containing the aqueous phase and the oral active agent.
