Abstract

A consumer product composition comprises a non-porous dissolvable solid structure comprising from about 30% to about 95%, by weight of the consumer product composition, of a carrier material, and from about 5% to about 50%, by weight of the consumer product composition, of a hydrophobic conditioning agent disposed within the carrier material of the non-porous dissolvable solid structure. The carrier material comprises a polyethylene glycol material, or mixtures thereof, having a molecular weight of from about 200 to about 50,000. The hydrophobic conditioning agent is selected from the group consisting of silicone materials, organic conditioning oils, hydrocarbon oils, fatty esters, metathesized unsaturated polyol esters, silane-modified oils, and mixtures thereof.

First claim

What is claimed is:

1. A consumer product composition comprising
a non-porous dissolvable solid structure comprising from about 50% to about 95%, by weight of said consumer product composition, of a carrier material, wherein said carrier material is a polyethylene glycol material having a molecular weight of from about 200 to about 50,000, and
from about 12% to about 50%, by weight of said consumer product composition, of a silicone hydrophobic conditioning agent disposed within said polyethylene glycol carrier material, wherein the mean particle size of said silicone hydrophobic conditioning agent disposed within said polyethylene glycol carrier material is from about 2 μm to about 2000 μm;
wherein said consumer product composition comprises less than about 3%, by weight of said consumer product composition, of detersive surfactant and/or cleansing surfactant; and
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 50mm.

2. The consumer product composition of claim 1 , wherein said polyethylene glycol material has a molecular weight of from about 500 to about 20,000.

3. The consumer product composition of claim 1 , wherein said polyethylene glycol material has a molecular weight of from about 1,000 to about 15,000.

4. The consumer product composition of claim 1 , wherein said consumer product composition comprises from about 12% to about 40%, by weight of said consumer product composition, of said silicone hydrophobic conditioning agent.

5. The consumer product composition of claim 1 , wherein said consumer product composition comprises from about 15% to about 40%, by weight of said consumer product composition, of said silicone hydrophobic conditioning agent.

6. The consumer product composition of claim 1 , wherein said consumer product composition comprises from about 60% to about 95%, by weight of the consumer product composition, of said polyethylene glycol carrier material.

7. The consumer product composition of claim 1 , wherein said silicone hydrophobic conditioning agent has a viscosity at 70° C. of from about 0.1 to about 2000 Pa·s.

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

9. The consumer product composition of claim 1 , wherein said silicone hydrophobic conditioning agent has a viscosity at 25° C. of from about 0.1 to about 2000 Pa·s.

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

11. The consumer product composition of claim 1 , wherein said polyethylene glycol carrier material has a melting point of from about 25° C. to about 120° C.

12. The consumer product composition of claim 1 , wherein said polyethylene glycol carrier material is a solid at 25° C.

13. The consumer product composition of claim 1 , wherein a ratio of the viscosity of said silicone hydrophobic conditioning agent at 70° C. to the viscosity of said polyethylene glycol carrier material at 70° C. is from about 1000:1 to about 1:1000.

14. The consumer product composition of claim 1 , wherein said polyethylene glycol carrier material disperses completely in 25° C. water within a Dispersion Time of less than 60 minutes.

15. The consumer product composition of claim 1 , wherein said polyethylene glycol carrier material disperses completely in 25° C. water within a Dispersion Time of less than about 10 minutes.

16. The consumer product composition of claim 1 , wherein the mean particle size of said silicone hydrophobic conditioning agent disposed within said polyethylene glycol carrier material is from about 2 μm to about 500 μm.

17. The consumer product composition of claim 1 , wherein the mean particle size of said silicone hydrophobic conditioning agent disposed within said polyethylene glycol carrier material is from about 2 μm to about 120 μm.

18. The consumer product composition of claim 1 , wherein said silicone hydrophobic conditioning agent comprises a terminal aminosilicone or a polydimethylsiloxane.

19. 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 0.3 to about 10 mm.

20. 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 0.5 to about 5 mm.

21. The consumer product composition of claim 1 , wherein said consumer product composition is in the form of a plurality of beads having an average aspect ratio of from about 1:1 to about 1000:1.

22. The consumer product composition of claim 1 , wherein said consumer product composition comprises a ratio of the level of polyethylene glycol carrier material to the level of silicone hydrophobic conditioning agent of from about 1:1 to about 20:1.

23. 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.

24. 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.

25. 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.
