Abstract

A consumer product composition comprises a non-porous dissolvable solid structure comprising a carrier material, and hydrophobic conditioning agent and particulate spacer material disposed within the carrier material, wherein the hydrophobic conditioning agent has a mean particle size of from about 1 μm to about 500 μm and the particulate spacer material has a mean particle size of from about 55 μm to about 750 μm.

First claim

What is claimed is:

1. A consumer product composition comprising:
a) a non-porous dissolvable solid structure comprising polyethylene glycol as a carrier material;
b) a hydrophobic conditioning agent disposed within said carrier material, wherein said hydrophobic conditioning agent is a terminal aminosilicone or a polydimethyl siloxane that has a mean particle size of from about 1 μm to about 500 μm; and
c) a particulate spacer material disposed within said carrier material, wherein said particulate spacer material is selected from the group consisting of glass microspheres, ceramic microspheres, polyalkylene microspheres, alkali metal borates, and mixtures thereof, and has a mean particle size of from about 55 μm to about 750 μm;
wherein said non-porous dissolvable solid structure of said consumer product composition comprises a volume fraction of said particulate spacer material of from about 0.05 to about 0.50; and
wherein said particulate spacer material is water-insoluble or a ratio of dissolution rate of said carrier material to dissolution rate of said particulate spacer material is at least about 2.

2. The consumer product composition of claim 1 , wherein said mean particle size of said particulate spacer material is greater than said mean particle size of said hydrophobic conditioning agent.

3. The consumer product composition of claim 1 , wherein a ratio of said mean particle size of said particulate spacer material to said mean particle size of said hydrophobic conditioning agent is at least about 5:1.

4. The consumer product composition of claim 1 , wherein said mean particle size of said particulate spacer material is from about 75 μm to about 650 μm.

5. The consumer product composition of claim 1 , wherein said consumer product composition comprises from about 5% to about 50%, by weight of said consumer product composition, of said particulate spacer material.

6. The consumer product composition of claim 1 , wherein said non-porous dissolvable solid structure of said consumer product composition comprises a volume fraction of said particulate spacer material of from about 0.1 to about 0.5.

7. The consumer product composition of claim 1 , wherein said particulate spacer material is water-insoluble.

8. The consumer product composition of claim 1 , wherein said particulate spacer material is a solid at 70° C.

9. The consumer product composition of claim 1 , wherein said particulate spacer material is colored, preferably said particulate spacer material having a color different from said carrier material such that a visual contrast is obtained between said carrier material and said particulate spacer material.

10. The consumer product composition of claim 1 , wherein the mean particle size of said hydrophobic conditioning agent disposed within said carrier material is from about 1 μm to about 500 μm.

11. The consumer product composition of claim 1 , wherein said consumer product composition comprises at least about 1%, by weight of said consumer product composition, of said hydrophobic conditioning agent.

12. The consumer product composition of claim 1 , wherein said consumer product composition comprises from about 30% to about 95%, by weight of the consumer product composition, of said carrier material.

13. The consumer product composition of claim 1 , wherein said hydrophobic conditioning agent is a liquid at 25° C.

14. The consumer product composition of claim 1 , wherein said carrier material has a viscosity at 70° C. of from about 0.005 to about 350 Pa·s.

15. The consumer product composition of claim 1 , wherein said carrier material has a melting point of from about 25° C. to about 120° C. and is a solid at 25° C.

16. The consumer product composition of claim 1 , wherein said carrier material comprises a polyethylene glycol material having a molecular weight of from about 200 to about 50,000.

17. The consumer product composition of claim 1 , wherein said consumer product composition is in the form of a plurality of beads, having an average maximum cross-sectional dimension of from about 0.05 to about 50 mm.

18. The consumer product composition of claim 1 , wherein said consumer product composition comprises less than about 5%, by weight of said consumer product composition, of water.

19. The consumer product composition of claim 1 , wherein said consumer product composition comprises less than about 5%, by weight of said consumer product composition, of detersive surfactant and/or cleansing surfactant.

20. The consumer product composition of claim 1 , wherein said consumer product composition further comprises a filler material selected from the group consisting of inorganic salts, carbohydrates, clays, metal oxides, zeolites, silicas, and urea.

21. A method of treating a surface comprising the steps of:
providing a consumer product composition according to claim 1 ;
providing an aqueous solution;
dissolving said consumer product composition in said aqueous solution to form an aqueous treatment liquor; and
contacting said surface with said aqueous treatment liquor.
