Abstract

A composition including a plurality of particles, the particles including about 25% to about 94% by weight a water soluble carrier; about 5% to about 45% by weight a quaternary ammonium compound; about 1% to about 40% by weight a fatty acid; and about 0.5% to about 10% by weight a cationic polymer; wherein each of the particles has a mass from about 1 mg to about 1 g.

First claim

What is claimed is:

1. A composition comprising a plurality of particles, said particles comprising:
about 25% to about 94% by weight a water soluble carrier;
about 5% to about 45% by weight a quaternary ammonium compound;
about 1% to about 40% by weight a fatty acid; and
about 0.5% to about 10% by weight a cationic polymer;
wherein each of said particles has a mass from about 1 mg to about 1 g.

2. The composition according to claim 1 , wherein said quaternary ammonium compound is an ester quaternary ammonium compound.

3. The composition according to claim 2 , wherein said particles comprise about 10% to about 40% by weight said quaternary ammonium compound.

4. The composition according to claim 3 , wherein said particles comprise about 1% to about 5% by weight said cationic polymer.

5. The composition according to claim 4 , wherein said cationic polymer is a cationic polysaccharide.

6. The composition according to claim 5 , wherein said water soluble carrier is selected from the group consisting of polyethylene glycol, sodium acetate, sodium bicarbonate, sodium chloride, sodium silicate, polypropylene glycol polyoxoalkylene, polyethylene glycol fatty acid ester, polyethylene glycol ether, sodium sulfate, starch, and mixtures thereof.

7. The composition according to claim 6 , wherein said carrier comprises polyethylene glycol having a weight average molecular weight from about 2000 to about 13000.

8. The composition according to claim 6 , wherein said cationic polymer is a cationic polysaccharide, wherein said cationic polysaccharide is polymeric quaternary ammonium salt of hydroxyethylcellulose which has been reacted with an epoxide substituted with a trimethylammonium group.

9. The composition according to claim 6 , wherein said particles are less than about 10% by weight water.

10. The composition according to claim 6 , wherein said particles have a Dispersion Time less than about 30 minutes.

11. The composition according to claim 6 , wherein said particles have an onset of melt from about 25° C. to about 120° C.

12. The composition according to claim 6 , wherein said particles are substantially homogeneously structured particles.

13. The composition according to claim 1 , wherein said cationic polymer is a cationic polysaccharide.

14. The composition according to claim 1 , wherein said water soluble carrier is selected from the group consisting of polyethylene glycol, sodium acetate, sodium bicarbonate, sodium chloride, sodium silicate, polypropylene glycol polyoxoalkylene, polyethylene glycol fatty acid ester, polyethylene glycol ether, sodium sulfate, starch, and mixtures thereof.

15. The composition according to claim 1 , wherein said cationic polymer is a cationic polysaccharide, wherein said cationic polysaccharide is polymeric quaternary ammonium salt of hydroxyethylcellulose which has been reacted with an epoxide substituted with a trimethylammonium group.

16. The composition according to claim 1 , wherein said particles are less than about 10% by weight water.

17. The composition according to claim 1 , wherein said water soluble carrier is a water soluble polymer.

18. The composition according to claim 1 , wherein said particles further comprise a material selected from the group consisting of perfume, dipropylene glycol, and mixtures thereof.

19. The composition according to claim 1 , wherein said particles are substantially homogeneously structured particles.

20. A process for treating an article of clothing comprising the steps of:
providing an article of clothing in a washing machine; and
contacting said article of clothing during a wash sub-cycle of said washing machine with the composition according to claim 1 .
