Abstract

A process for treating an article of clothing including the steps of: providing an article of clothing in a washing machine; contacting the article of clothing during a wash sub-cycle of the washing machine with a composition including a plurality of particles, the 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; and about 0.5% to about 10% 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 process for treating an article of clothing comprising the steps of:
a) providing an article of clothing in a washing machine;
b) contacting said article of clothing during a wash sub-cycle of said washing machine with a composition comprising a plurality of particles, wherein each of said particles has a mass from about 1 mg to about 1 g, and said particles comprise:
i) about 25% to about 94% by weight of a water soluble carrier;
ii) about 5% to about 45% by weight of an ester quaternary ammonium compound, wherein said ester quaternary ammonium compound is formed from a parent fatty acid compound having an Iodine Value from about 18 to about 60; and
iii) about 0.5% to about 10% a cationic polymer, wherein said particles have an onset of melt from about 25° C. to about 120° C.

2. The process according to claim 1 , wherein said washing machine comprises a wash basin within said washing machine, wherein said particles are placed in said wash basin before said article of clothing is placed in said wash basin.

3. The process according to claim 1 , further comprising the step of contacting said article of clothing during a wash sub-cycle with a detergent composition comprising an anionic surfactant.

4. The process according to claim 3 , further comprising the step of providing said detergent composition and said particles from separate packages.

5. The process according to claim 1 , wherein said particles comprise about 10% to about 40% by weight said quaternary ammonium compound.

6. The process according to claim 5 , wherein said particles comprise about 1% to about 5% by weight said cationic polymer.

7. The process according to claim 6 , wherein said cationic polymer is a cationic polysaccharide.

8. The process 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.

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

10. The process according to claim 7 , where said particles further comprise from about 1% to about 40% by weight fatty acid.

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

12. The process according to claim 11 , wherein said cationic polysaccharide is polymeric quaternary ammonium salt of hydroxyethylcellulose which has been reacted with an epoxide substituted with a trimethylammonium group.

13. The process 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.

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

15. A process for treating an article of clothing comprising the steps of:
a) providing an article of clothing in a washing machine;
b) contacting said article of clothing during a wash sub-cycle of said washing machine with a composition comprising a plurality of particles, wherein each of said particles has mass from about 1 mg to about 1 g, and said particles comprise:
i) about 25% to about 94% by weight of a water soluble carrier;
ii) about 5% to about 45% by weight of an ester quaternary ammonium compound, wherein said ester quaterny ammonium compound is formed from a parent fatty acid compound having an lodine Value about 18 to 60; and
iii) about 0.5% to about 10% a cationic polymer.

16. The process according to claim 15 , wherein said water soluble carrier is selected from the group consisting of polyethylene gycol, sodium acetate, sodium bicarbonate, sodium chloride, sodium silicate, polypropylene glycol polyoxoalkylene, polethylene glycol fatty acid ester, polyethylene glycol ether, sodium sulfate, starch, and mixtures thereof.

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

18. The process according to claim 15 , wherein said cationic polymer is a cationic polysaccharide.

19. The process according to claim 1 , wherein said particles comprise 30% to about 94% by weight a water soluble carrier.

20. The process according to claim 1 , wherein each of said particles has a mass from about 10 mg to about 1 g.

21. The process according to claim 1 , wherein said particles comprise 30% to about 94% by weight a water soluble carrier.

22. The process according to claim 21 , wherein each of said particles has a mass from about 10 mg to about 1 g.
