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.

Claims (18)

1. A composition consisting essentially of:

(a) from about 80 % to about 91 % by weight of said composition of polyethylene glycol, wherein said polyethylene glycol has a molecular weight from about 5,000 to about 11,000;
(b) from about 2 % to about 12 % by weight of said composition free perfume;
and (c) from about 2 % to about 12 % by weight of said composition of friable perfume microcapsule, wherein said 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.
2. The composition of claim 1, wherein said friable perfume microcapsule comprises a melamine/formaldehyde shell and said friable perfume microcapsule encapsulates from about 0.6% to about 4% by weight of said composition of perfume.
3. The composition of Claim 1, wherein said pastille has a shape selected from the group consisting of spherical, hemispherical, compressed hemispherical, lentil shaped, and oblong.
4. The composition of Claim 1, wherein said pastille has a maximum dimension less than 1 centimeter.
5. A method of treating laundry comprising the step of dosing a composition according to Claim 1 to a laundry washing machine or a laundry wash basin.
6. A unit dose of a fabric treatment composition comprising a plurality of pastilles, wherein each pastille comprises:
(a) from about 80 % to about 91 % by weight of said composition of polyethylene glycol, wherein said polyethylene glycol has a molecular weight from about 5,000 to about 11,000;

(b) from about 2 % to about 12 % by weight of said composition free perfume;
and (c) from about 2% to about 12 % by weight of said composition of friable perfume microcapsule, wherein said perfume microcapsule comprises encapsulated perfume;

wherein each said pastille has a mass from about 0.95 mg to about 2 g; and wherein said plurality of pastilles has a mass from about 13 g to about 27 g to comprise said unit dose.
7. The unit dose of fabric treatment composition of Claim 6, wherein said friable microcapsule comprises a melamine/formaldehyde shell and said friable perfume microcapsule encapsulates from about 0.6% to about 4% by weight of said composition of perfume.
8. The unit dose of fabric treatment composition of Claim 6, 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.
9. The unit dose of fabric treatment composition of Claim 6, wherein said pastilles have a maximum dimension less than 1 centimeter.
10. A method of treating laundry comprising the step of dosing said unit dose of fabric treatment composition according to Claim 6 to a laundry washing machine or a laundry wash basin.
11. The method of claim 10, wherein said unit dose of fabric treatment composition is contained in a package, wherein said package comprises a dosing means, wherein the method further comprises the step of dispensing said unit dose of fabric treatment composition contained in said package to said dosing means and thereafter dispensing said unit dose of fabric treatment composition to said laundry washing machine or said laundry wash basin from the dosing means.
12. A composition consisting essentially of:
(a) from about 80 % to about 91 % by weight of said composition of polyethylene glycol, wherein said polyethylene glycol has a molecular weight from about 5,000 to about 11,000; and (b) from about 9 % to about 20 % by weight of said composition of a friable perfume microcapsule, wherein said perfume microcapsule comprises encapsulated perfume;
wherein said composition is essentially free of free perfume; and wherein said composition is shaped in a pastille having a mass from about 0.95 mg to about 2 g.
13. A composition consisting essentially of:
(a) from about 80 % to about 91 % by weight of said composition of polyethylene glycol, wherein said polyethylene glycol has a molecular weight from about 5,000 to about 11,000; and (b) from about 9 % to about 20 % by weight of said composition of free perfume;

providing said viscous material at a processing temperature less than 20 degrees Celsius higher than said glass transition temperature; and
15 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.

15. The method of Claim 14, wherein said perfume microcapsule is a friable microcapsule and comprises a melamine/formaldehyde shell, said perfume microcapsule encapsulating from about 0.6% to about 4% by weight of said composition of perfume.
16. The method of Claim 14, wherein said plurality of pastilles include pastilles having a shape selected from the group consisting of spherical, hemispherical, compressed hemispherical, lentil shaped, and oblong.
17. The method of Claim 14, wherein said pastilles have a maximum dimension less than 1 centimeter.
