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; 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; and wherein the composition has a viscosity from about 1 Pa-s to about 10 Pa-s at 65° C.

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, wherein said water soluble carrier further comprises a material selected from the group consisting of 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;
about 10% to about 40% by weight a quaternary ammonium compound, wherein said quaternary ammonium compound is an ester quaternary ammonium compound; and
about 1% to about 5% by weight a cationic polymer, wherein said cationic polymer is a cationic polysaccharide;
wherein each of said particles has a mass from about 1 mg to about 1 g;
wherein a melt of said composition has a viscosity from about 1 Pa-s to about 10 Pa-s at 65° C.; and
wherein said particles further comprise from about 1% to about 40% by weight fatty acid.

2. The composition according to claim 1 , wherein said water soluble carrier is polyethylene glycol having a weight average molecular weight from about 2000 to about 13000.

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

4. The composition according to claim 1 , wherein said particles have a Dispersion Time less than about 30 minutes.

5. The composition according to claim 1 , wherein said particles have an onset of melt from about 25° C. to about 50° C.

6. The composition according to claim 1 , wherein said quaternary ammonium compound is di-(tallowoyloxyethyl)-N,N-methylhydroxyethylammonium methyl sulfate.

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

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

10. 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 .

11. 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 0.5% to about 10% by weight a cationic polymer; and
about 1% to about 40% by weight fatty acid;
wherein each of said particles has a mass from about 1 mg to about 1 g; and
wherein a melt of said composition has a viscosity from about 1 Pa-s to about 10 Pa-s at 65° C.

12. The composition according to claim 11 , wherein said quaternary ammonium compound is an ester quaternary ammonium compound.

13. The composition according to claim 12 , wherein said cationic polymer is a cationic polysaccharide.

14. The composition according to claim 11 , wherein said water soluble carrier is a water soluble polymer.

15. The composition according to claim 11 , wherein said particles are less than about 10% by weight water.

16. The composition according to claim 11 , wherein said particles have a Dispersion Time less than about 30 minutes.

17. The composition according to claim 11 , wherein said particles have an onset of melt from about 25° C. to about 50° C.

18. The composition according to claim 11 , wherein said quaternary ammonium compound is di-(tallowoyloxyethyl)-N,N-methylhydroxyethylammonium methyl sulfate.

19. The composition according to claim 18 , 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.

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 11 .
