Abstract

A composition comprising: (a) a fragrance oil comprising: (i) top note perfume raw material, or mixture of perfume raw materials, with a boiling point of less than, or equal to, about 250° C. at 1 atmosphere pressure; (ii) middle or base note perfume raw material, or mixture of perfume raw materials, with a boiling point of greater than 250° C. at 1 atmosphere pressure; (b) an entrapment material which is selected from the group consisting of polymers; capsules, microcapsules and nanocapsules; liposomes; pro-perfumes selected from more than 1 type of pro-chemistry; film formers; absorbents; cyclic oligosaccharides and mixtures thereof; (c) greater than 50% volatile solvent; wherein the weight ratio of the top note perfume raw materials to middle or base note perfume raw materials within the fragrance oil is in the range from about 1:20 to about 20:1. The present invention provides compositions wherein the light, fresh, fruity, citrus, green or delicate floral top note fragrance character remains detectable for greater than about 2 hours, preferably greater than about 4 hours, more preferably greater than about 6 hours, after the composition has been applied to the substrate.

Claims

1. A method of treating laundry comprising the step of using an article, wherein the article comprises:

(a) a substrate and;

(b) a laundry composition comprising;

(i) a capsule, microcapsule, or nanocapsule; and

(ii) a fragrance oil;

wherein the capsule, microcapsule, or nanocapsule encapsulates a fragrance oil; and

wherein the capsule, microcapsule, or nanocapsule is ruptured mechanically before the fragrance oil is released.

2. The method of claim 1, wherein the encapsulated fragrance oil is physically associated with the capsule, microcapsule, or nanocapsule.

3. The method of claim 2, wherein the encapsulated fragrance oil forms a reversible association with the capsule, microcapsule, or nanocapsule

4. The method of claim 2, wherein the capsule, microcapsule, or nanocapsule is water insensitive.

5. The method of claim 4, wherein the fragrance oil comprises perfume raw materials, and wherein the 5% to about 60% of the perfume raw material, by weight of the fragrance oil, comprise a boiling point of less than or equal to about 250°

C.

6. The method of claim 5, wherein the boiling point is measured at 1 atmosphere.

7. The method of claim 4, wherein from about 20% to about 40% of the raw perfume ingredients comprise an odour detection threshold of less than or equal to 50 parts per billion.

8. The method of claim 7, wherein the odour detection threshold is less than or equal to 10 parts per billion.

9. The method of claim 6, wherein from about 20% to about 40% of the raw perfume ingredients comprise an odour detection threshold of less than or equal to 50 parts per billion.

10. The method of claim 9, wherein the encapsulate fragrance oil is encapsulated by the microcapsule.

11. The method of claim 10, wherein the laundry composition comprises from about 0.1% to about 5% water.

12. The method of claim 10, wherein the laundry composition is substantially free of water.

13. The method of claim 4, wherein the laundry composition comprises from about 0.1% to about 5% water.

14. The method of claim 4, wherein the laundry composition is substantially free of water.
