Abstract

A composition including: (i) a plurality of first particles comprising: about 25% to about 94% by weight a water soluble first carrier; and a perfume; wherein each of the first particles has a mass from about 1 mg to about 1 g; (ii) a plurality of second particles having: about 25% to about 94% by weight a water soluble second 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 second particles has a mass from about 1 mg to about 1 g; wherein the first particles and the second particles are in a package.

Claims (33)

1 . A composition comprising:

(i) a plurality of first particles comprising:

about 25% to about 94% by weight a water soluble first carrier; and

a perfume;

wherein each of said first particles has a mass from about 1 mg to about 1 g;

(ii) a plurality of second particles comprising:

about 25% to about 94% by weight a water soluble second 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 said second particles has a mass from about 1 mg to about 1 g;

wherein said first particles and said second particles are in a package; and

wherein said first particles and said second particles have at least one substantially flat or flat surface.

2 . The composition according to claim 1 , wherein said first carrier and said second carrier are a water soluble polymer.

3 . The composition according to claim 2 , wherein said composition comprises from about 10% to about 90% by weight said first particles and from about 10% to about 90% by weight said second particles.

4 . The composition according to claim 3 , wherein said first particles have a first particles onset of melt and said second particles have a second particles onset of melt, wherein said first particles onset of melt and said second particles onset of melt differ by less than about 20° C.

5 . The composition according to claim 4 , where said first particles and said second particles mixed together have a coefficient of uniformity of less than about 2.

6 . The composition according to claim 5 , wherein said first particles have a first particles D50 and said second particles have a second particles D50, wherein said second particles D50 is within about 20% of said first particles D50.

7 . The composition according to claim 6 , wherein said first particles and said second particles are together in a single chamber of said package.

8 . The composition according to claim 7 , wherein said first particles and said second particles are substantially homogeneously structured particles.

9 . The composition according to claim 7 , wherein said perfume comprises encapsulated perfume.

10 . The composition according to claim 1 , wherein said first carrier and said second carrier are 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.

11 . The composition according to claim 1 , wherein said composition comprises from about 10% to about 50% by weight said first particles and from about 50% to about 90% by weight said second particles.

12 . The composition according to claim 1 , wherein said composition comprises said first particles and said second particles at a ratio of mass of said second particles to mass of said first particles greater than about 1:1.

13 . The composition according to claim 1 , wherein said composition comprises from more than 0% to about 8% by weight anionic surfactant.

14 . The composition according to claim 1 , wherein said first particles have a first particles onset of melt and said second particles have a second particles onset of melt, wherein said first particles onset of melt and said second particles onset of melt differ by less than about 20° C.

15 . The composition according to claim 1 , where said first particles and said second particles mixed together have a coefficient of uniformity of less than about 2.

16 . The composition according to claim 1 , wherein said first particles have a first particles D50 and said second particles have a second particles D50, wherein said second particles D50 is within about 20% of said first particles D50.

17 . The composition according to claim 1 , wherein said first particles and said second particles are together in a single chamber of said package.

18 . The composition according to claim 1 , wherein said perfume comprises encapsulated perfume.

19 . The composition according to claim 1 , wherein said first particles and said second 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 a composition according to claim 1 .
