Abstract

A composition including a plurality of particles, the plurality of 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 the plurality of particles comprises individual particles that comprise at least one of the quaternary ammonium compound and the cationic polymer; wherein the individual particles differ from one another in weight fraction of at least one of the quaternary ammonium compound and the cationic polymer; and wherein the individual particles each have a mass from about 1 mg to about 1 g.

Claims (43)

1. A composition comprising a plurality of particles, said plurality of particles comprising:

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 said plurality of particles comprises individual particles that comprise at least one of said quaternary ammonium compound and said cationic polymer;

wherein said particles are substantially homogeneously structured particles; and

wherein said individual particles each have a mass from about 1 mg to about 1 g.

2. The composition according to claim 1 , wherein said quaternary ammonium compound formed from a parent fatty acid compound having an Iodine Value from about 18 to about 60.

3. The composition according to claim 2 , wherein said cationic polymer is a cationic polysaccharide.

4. The composition according to claim 2 , wherein said plurality of particles further comprises perfume.

5. The composition according to claim 2 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.

6. The composition according to claim 2 , wherein said plurality of particles further comprises fatty acid.

7. 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 .

8. A composition comprising a plurality of particles, said plurality of particles comprising:

about 25% to about 84% by weight a water soluble carrier;

about 15% to about 45% by weight a quaternary ammonium compound; and

about 0.5% to about 10% by weight a cationic polymer;

wherein said plurality of particles comprises individual particles that comprise at least one of said quaternary ammonium compound and said cationic polymer; and

wherein said individual particles each have a mass from about 1 mg to about 1 g.

9. The composition according to claim 8 , wherein said quaternary ammonium compound formed from a parent fatty acid compound having an Iodine Value from about 18 to about 60.

10. The composition according to claim 9 , wherein said cationic polymer is a cationic polysaccharide.

11. The composition according to claim 9 , wherein said plurality of particles further comprises perfume.

12. The composition according to claim 9 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.

13. The composition according to claim 9 , wherein said plurality of particles further comprises fatty acid.

14. 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 8 .

15. A composition comprising a plurality of particles, said plurality of particles comprising:

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 said plurality of particles comprises individual particles that comprise at least one of said quaternary ammonium compound and said cationic polymer; and

wherein said individual particles differ from one another in weight fraction of at least one of said quaternary ammonium compound and said cationic polymer; and

wherein said individual particles each have a mass from about 1 mg to about 1 g.

16. The composition according to claim 15 , wherein said quaternary ammonium compound formed from a parent fatty acid compound having an Iodine Value from about 18 to about 60.

17. The composition according to claim 16 , wherein said cationic polymer is a cationic polysaccharide.

18. The composition according to claim 16 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.

19. The composition according to claim 16 , wherein said plurality of particles comprises:
