15 Claims

1. A cleaning implement comprising:

a) an erodible foam adapted to contact a surface to be cleaned, and

b) a rheological solid composition comprising:

crystallizing agent and aqueous phase;

wherein, the rheological solid composition has a firmness between about 0.1 N to about 50.0 N as determined by the FIRMNESS TEST METHOD;

a thermal stability of about 40° C. to about 95° C. as determined by the THERMAL STABILITY TEST METHOD; and

a liquid expression of between about 100 Jm⁻³to about 8,000 Jm⁻³as determined by the AQUEOUS PHASE EXPRESSION TEST METHOD;

wherein the crystallizing agent is a salt of fatty acids containing from about 13 to about 20 carbon atoms;

wherein the crystallizing agent has an Optimal Purity Po as determined by the BLEND TEST METHOD greater than about 0.5; and

wherein the crystallizing agent is present in an amount from 1% to about 7% by weight of the rheological solid composition.
