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 formed from a parent fatty acid compound having an Iodine Value from about 18 to about 60; 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 10% to about 40% by weight a quaternary ammonium compound formed from a parent fatty acid compound having an Iodine Value from about 20 to about 60; and
about 1% to about 5% by weight a cationic polymer;
wherein each of said particles has a mass from about 1 mg to about 1 g;
wherein said particles have an onset of melt from about 25° C. to about 120° C.;
wherein said quaternary ammonium compound is an ester quaternary ammonium compound;
wherein said cationic polymer is a cationic polysaccharide;
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; 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 carrier comprises polyethylene glycol having a weight average molecular weight from about 2000 to about 13000.

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

4. The composition according to claim 3 , wherein said cationic polysaccharide is polymeric quaternary ammonium salt of hydroxyethylcellulose which has been reacted with an epoxide substituted with a trimethylammonium group.

5. 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.

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

7. 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 formed from a parent fatty acid compound having an Iodine Value from about 18 to about 60;
about 1% to about 40% by weight 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.

8. The composition according to claim 7 , wherein said quaternary ammonium compound is formed from a parent fatty acid compound having an Iodine Value from about 20 to about 60.

9. The composition according to claim 7 , 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.

10. The composition according to claim 7 , wherein said particles are less than about 10% by weight water.

11. The composition according to claim 7 , wherein said quaternary ammonium compound is an ester quaternary ammonium compound.

12. The composition according to claim 7 , wherein said quaternary ammonium compound is di-(tallowoyloxyethyl)-N,N-methylhydroxyethylammonium methyl sulfate.

13. The composition according to claim 7 , wherein said cationic polymer is a cationic polysaccharide.

14. The composition according to claim 13 , wherein said cationic polysaccharide is polymeric quaternary ammonium salt of hydroxyethylcellulose which has been reacted with an epoxide substituted with a trimethylammonium group.

15. The composition according to claim 14 , wherein said quaternary ammonium compound is di-(tallowoyloxyethyl)-N,N-methylhydroxyethylammonium methyl sulfate.

16. The composition according to claim 7 , wherein said quaternary ammonium compound is an ester quaternary ammonium compound and said cationic polymer is a cationic polysaccharide.

17. The composition according to claim 16 , wherein said cationic polysaccharide is polymeric quaternary ammonium salt of hydroxyethylcellulose which has been reacted with an epoxide substituted with a trimethylammonium group.

18. The composition according to claim 16 , wherein said particles have an onset of melt from about 25° C. to about 120° C.

19. The composition according to claim 16 , wherein said water soluble carrier is a water soluble polymer.

20. The composition according to claim 7 , wherein said particles have an onset of melt from about 25° C. to about 120° C.
