Abstract

A laundry scent additive having polyethylene glycol and perfume. The laundry scent additive enables consumers to control the amount of scent imparted to their laundry.

First claim

What is claimed is:

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, polyethylene glycol having a molecular weight less than 2,000, and mixtures thereof;
(b) from about 80% to about 91% by weight of said pastilles of polyethylene glycol, wherein said polyethylene glycol has a molecular weight from 2,000 to about 13,000; 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 having a molecular weight from 2,000 to about 13,000 between said pastilles of said first fabric treatment composition and said pastilles of said second fabric treatment composition of less than about 2%.

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 86% to about 90% by weight of said pastilles of polyethylene glycol having a molecular weight from 2,000 to about 13,000.

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

6. 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.

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

8. The array according to claim 1 , wherein said pastilles of said first fabric treatment composition have a first unencapsulated perfume and said pastilles of said second fabric treatment composition have a second unencapsulated perfume, wherein said first unencapsulated perfume differs from said second unencapsulated perfume.

9. The array according to claim 8 , 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.

10. The array according to claim 9 , wherein said difference in percentage by weight of polyethylene glycol having a molecular weight from 2,000 to about 13,000 between said pastilles of said first fabric treatment composition and said pastilles of said second fabric treatment composition is less than about 1%.

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

12. The array according to claim 9 , wherein said first fabric treatment composition is contained in a first package and said second fabric treatment composition is contained in a second package.

13. The array according to claim 12 , wherein said first fabric treatment composition and said second treatment composition are less than about 1 m apart from one another.

14. The array according to claim 8 , wherein said pastilles of said first fabric treatment composition have the same shape as said pastilles of said second fabric treatment composition.

15. The array according to claim 14 , 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.

16. The array according to claim 8 , 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.

17. The array according to claim 1 , 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.

18. 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, polyethylene glycol having a molecular weight less than 2,000, and mixtures thereof;
(b) from about 80% to about 91% by weight of said pastilles of polyethylene glycol, wherein said polyethylene glycol has a molecular weight from 2,000 to about 13,000;
(c) from about 1% to about 12% by weight of said pastilles unencapsulated perfume; and
(d) 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 having a molecular weight from 2,000 to about 13,000 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 unencapsulated perfume and said pastilles of said second fabric treatment composition have a second unencapsulated perfume, wherein said first unencapsulated perfume differs from said second unencapsulated 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.

19. 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, polyethylene glycol having a molecular weight less than 2,000, and mixtures thereof;
(b) polyethylene glycol, wherein said polyethylene glycol has a molecular weight from 2,000 to about 13,000;
