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. A composition comprising:
(a) polyethylene glycol;
(b) from about 2% to about 12% by weight of said composition of free perfume; and
(c) from about 2% to about 12% by weight of said composition of friable perfume microcapsule, wherein said friable perfume microcapsule comprises encapsulated perfume;
wherein said composition is shaped in a pastille having a mass from about 0.95 mg to about 2 g;
wherein said pastille has a shape selected from the group consisting of hemispherical and compressed hemispherical;
wherein said pastille is packaged in a package and a dispensing cap is releasably detachable from and reattachable to said package; and
wherein said package comprises a translucent portion and said pastille is viewable to a consumer.

2. The composition of claim 1 , wherein said composition comprises from about 65% to about 99% by weight of said composition of polyethylene glycol.

3. The composition of claim 1 , wherein said polyethylene glycol has a molecular weight from about 3,000 to about 13,000.

4. The composition of claim 1 , wherein said composition comprises from about 80% to about 95% by weight of said composition of polyethylene glycol.

5. The composition of claim 4 , wherein said friable perfume microcapsule comprises a melamine/formaldehyde shell.

6. The composition of claim 4 , wherein said friable perfume microcapsule encapsulates from about 0.6% to about 4% by weight of said composition of perfume.

7. The composition of claim 1 , wherein said pastille has a shape of compressed hemispherical.

8. The composition according to claim 7 , wherein said pastille has a ratio of height to diameter of about 0.1 to about 0.4.

9. The composition of claim 1 , wherein said pastille has a maximum dimension less than about 1 centimeter.

10. A method of treating laundry comprising the step of dosing from about 13 g to about 27 g of a composition according to claim 1 to a laundry washing machine or a laundry wash basin.

11. The method of claim 10 , wherein said composition is contained in a package, wherein said package comprises a dosing means, wherein the method further comprises the step of dispensing said fabric treatment composition contained in said package to said dosing means and thereafter dispensing said fabric treatment composition to said laundry washing machine or said laundry wash basin from the dosing means.

12. A method of making a composition comprising the steps of:
providing a viscous material having a glass transition temperature, said viscous material comprising:
(a) polyethylene glycol;
(b) free perfume; and
(c) perfume microcapsule, wherein said perfume microcapsule comprises encapsulated perfume;

providing said viscous material at a processing temperature less than about 20 degrees Celsius higher than said glass transition temperature; and
passing said viscous material through small openings and onto a moving conveyor surface upon which said viscous material is cooled below said glass transition temperature to form a plurality of pastilles;
wherein said pastilles have a shape of hemispherical or compressed hemispherical.

13. The method of claim 12 , wherein said viscous material comprises from about 2% to about 10% by weight of said composition of free perfume.

14. The method of claim 12 , wherein said viscous material comprises from about 2% to about 12% by weight of said composition of perfume microcapsule.

15. The method of claim 12 , wherein said viscous material comprises from about 2% to about 10% by weight of said composition of free perfume and wherein said viscous material comprises from about 2% to about 12% by weight of said composition of perfume microcapsule.

16. The method of claim 15 , wherein said polyethylene glycol has a molecular weight from about 3,000 to about 13,000.

17. The method of claim 12 , wherein said perfume microcapsule is a friable microcapsule and comprises a melamine/formaldehyde shell.

18. The method of claim 17 , wherein said perfume microcapsule encapsulates from about 0.6% to about 4% by weight of said composition of perfume.

19. The method of claim 12 , wherein said pastilles have a maximum dimension less than about 1 centimeter.

20. The method of claim 12 , wherein said pastilles have a mass from about 0.95 mg to about 2 g.
