Claims16
A cleaning implement comprising:
- a) an erodible foam adapted to contact a surface to be cleaned, the erodible foam having pores, and
- b) a rheological solid composition entrained within the pores of the erodible foam, the 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 J m−3 to about 8,000 J m−3 as 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 said crystallizing agent has an Optimal Purity Po as determined by the BLEND TEST METHOD greater than about 0.5;
- wherein said crystallizing agent has a Single Purity Ps as determined by the BLEND TEST METHOD greater than about 0.5;
- wherein the crystallizing agent is present in an amount from 1% to about 7% by weight of the rheological solid composition.
