Abstract

A cleaning implement for cleaning a target surface is provided that includes an erodible foam adapted to contact a surface to be cleaned and a rheological solid composition comprising a crystallizing agent and an aqueous phase.

First claim

What is claimed is:

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 −3 to about 8,000 Jm −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 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.

2. The cleaning implement of claim 1 , wherein said crystallizing agent has an Optimal Purity Po as determined by the BLEND TEST METHOD greater than about 0.7.

3. The cleaning implement of claim 1 , wherein said crystallizing agent has an Optimal Purity Po as determined by the BLEND TEST METHOD greater than about 0.8.

4. The cleaning implement of claim 1 , wherein said crystallizing agent has a Single Purity Ps as determined by the BLEND TEST METHOD greater than about 0.5.

5. The cleaning implement of claim 1 , wherein said crystallizing agent has a Single Purity Ps as determined by the BLEND TEST METHOD greater than about 0.6.

6. The cleaning implement of claim 1 , wherein said crystallizing agent has a Single Purity Ps as determined by the BLEND TEST METHOD greater than about 0.7.

7. The cleaning implement of claim 1 , wherein said crystallizing agent has a Single Purity Ps as determined by the BLEND TEST METHOD greater than about 0.9.

8. The cleaning implement of claim 1 , wherein the crystallizing agent is a metal salt.

9. The cleaning implement of claim 8 , wherein the metal salt is a sodium salt.

10. The cleaning implement of claim 9 , wherein the sodium salt is at least one of sodium stearate, sodium palmitate, sodium myristate.

11. The cleaning implement of claim 10 , wherein the sodium salt further comprises at least one of sodium tridecanoate, sodium pentadecanoate, sodium heptadecanoate and sodium nonadecanoate.

12. The cleaning implement of claim 1 , wherein the crystallizing agent is present in an amount from 1% to about 5% by weight of the rheological solid composition.

13. The cleaning implement of claim 1 , wherein the crystallizing agent is present in an amount from about 2% to about 4% by weight of the rheological solid composition.

14. The cleaning implement of claim 1 , wherein the rheological solid composition, has a firmness between about 0.5 N to about 25.00 N as determined by the FIRMNESS TEST METHOD.

15. The cleaning implement of claim 1 , wherein the rheological solid composition, has a firmness between 1.0 N to about 20.0 N as determined by the FIRMNESS TEST METHOD.
