Claims

1. An array of fabric treatment compositions each member of said array being a fabric treatment composition comprising a plurality of pastilles, wherein said pastilles comprise:

(a) from about 0.1% to about 10% by weight of said pastilles of a balancing agent selected from the group consisting of glycerin, polypropylene glycol, isopropyl myristate, dipropylene glycol, 1,2 propanediol, and mixtures thereof;

(b) polyethylene glycol; and

(c) from about 0.1% to about 12% by weight of said pastilles of friable perfume microcapsule, wherein said friable perfume microcapsule comprises encapsulated perfume;

wherein said array comprises at least a first fabric treatment composition and a second fabric treatment composition, wherein there is a difference in percentage by weight of polyethylene glycol between said pastilles of said first fabric treatment composition and said pastilles of said second fabric treatment composition of less than about 2%;

wherein said pastilles of said first fabric treatment composition have a first encapsulated perfume and said pastilles of said second fabric treatment composition have a second encapsulated perfume, wherein said first encapsulated perfume differs from said second encapsulated perfume.

2. The array according to claim 1, wherein said pastilles comprise from about 1% to about 12% by weight of said pastilles unencapsulated perfume.

3. The array according to claim 2, wherein said balancing agent is selected from the group consisting of isopropyl myristate, dipropylene glycol, and mixtures thereof.

4. The array according to claim 3, wherein said pastilles comprise from about 0.5% to about 5% by weight of said pastilles of said balancing agent.

5. The array according to claim 1, wherein said plurality of pastilles includes individual pastilles having a shape selected from the group consisting of spherical, hemispherical, compressed hemispherical, lentil shaped, and oblong.

6. The array according to claim 1, wherein individual pastilles have a mass from 0.95 mg to 2 g.

7. The array according to claim 1, wherein said pastilles of said first fabric treatment composition comprises from about 1% to about 12% by weight of said first fabric treatment composition unencapsulated perfume and said pastilles of said second fabric treatment composition comprise from about 1% to about 12% by weight of said second fabric treatment composition unencapsulated perfume.

8. The array according to claim 7, wherein said difference in percentage by weight of polyethylene glycol between said pastilles of said first fabric treatment composition and said pastilles of said second fabric treatment composition is less than about 1%.

9. The array according to claim 7, wherein said balancing agent is selected from the group consisting of isopropyl myristate, dipropylene glycol, and mixtures thereof.

10. The array according to claim 1, wherein said first fabric treatment composition is contained in a first package and said second fabric treatment composition is contained in a second package.

11. The array according to claim 10, wherein said first fabric treatment composition and said second treatment composition are less than about 1 m apart from one another.

12. The array according to claim 1, wherein said pastilles of said first fabric treatment composition have the same shape as said pastilles of said second fabric treatment composition.

13. The array according to claim 12, wherein said pastilles of said first fabric treatment composition and said pastilles of said second fabric treatment composition differ in shape by less than about 2 mm in any dimension.

14. The array according to claim 1, wherein pastilles of said first fabric treatment composition comprise a first dye and said pastilles of said second fabric treatment composition comprise a second dye, wherein said first dye differs from said second dye.

15. An array of fabric treatment compositions each member of said array being a fabric treatment composition comprising a plurality of pastilles, wherein said pastilles comprise:

(a) from about 0.1% to about 10% by weight of said pastilles of a balancing agent selected from the group consisting of glycerin, polypropylene glycol, isopropyl myristate, dipropylene glycol, 1,2 propanediol, and mixtures thereof;

(b) polyethylene glycol; and

(c) from about 0.1% to about 12% by weight of said pastilles of friable perfume microcapsule, wherein said friable perfume microcapsule comprises encapsulated perfume;

wherein said array comprises at least a first fabric treatment composition and a second fabric treatment composition, wherein there is a difference in percentage by weight of polyethylene glycol between said pastilles of said first fabric treatment composition and said pastilles of said second fabric treatment composition of less than about 2%;

wherein said pastilles of said first fabric treatment composition have a first encapsulated perfume and said pastilles of said second fabric treatment composition have a second encapsulated perfume, wherein said first encapsulated perfume differs from said second encapsulated perfume;

wherein said pastilles of said first fabric treatment composition and said pastilles of said second fabric treatment composition differ in shape by less than about 2 mm in any dimension;

wherein said pastilles of said first fabric treatment composition comprise a first dye and said pastilles of said second fabric treatment composition comprise a second dye, wherein said first dye differs from said second dye; and

wherein individual pastilles of said first fabric treatment composition and individual pastilles of said second fabric treatment composition have an individual mass from 0.95 mg to 2 g.

16. An array of fabric treatment compositions each member of said array being a fabric treatment composition comprising a plurality of pastilles, wherein said pastilles comprise:
