Abstract

The present disclosure provides fragrance compositions having an olfactive profile that changes with time. The fragrance compositions include at least two contrasting perfume accords. The at least two contrasting perfume accords provide an olfactory modulating effect, such that the fragrance compositions deliver a desirable scent with increased perceived intensity and improved longevity of perception.

First claim

The invention claimed is:

1. A perfume composition comprising at least two perfuming accords,
wherein a first perfume accord of the at least two perfuming accords comprises perfuming compounds dominated by a first olfactive note selected from the group consisting of fruity, mango, and passion-fruit olfactive notes,
wherein a second perfume accord of the at least two perfuming accords comprises perfuming compounds dominated by a second olfactive note selected from the group consisting of almond, coconut, and woody olfactive notes,
wherein the first perfume accord is present in the perfume composition in an amount sufficient for the first olfactive note to be perceived by a subject at a first time,
wherein the second perfume accord is present in the perfume composition in an amount sufficient for the second olfactive note to be perceived by a subject at a second time,
wherein the perception of the first olfactive note and the second olfactive note is at a level sufficient to reduce, prevent, or suppress a reduced perception of the perfume composition by the subject over time,
wherein the first perfume accord and the second perfume accord are present in the perfume composition in a weight ratio ranging from 3:1 to 1:3,
wherein the first perfume accord further comprises a mixture comprising the first perfume accord encapsulated within a first matrix material, wherein the first matrix material is a core-shell capsule,
wherein the second perfume accord is not confined in the first matrix material, and
wherein the first perfume accord comprises perfuming compounds having a volatility ranging from 70,000 to 100 μg/l in air.

2. The perfume composition of claim 1 , wherein the second time is after the first time.

3. The perfume composition of claim 1 , wherein the second perfume accord comprises perfuming compounds having a volatility ranging from 99 to 50 μg/l in air.

4. The perfume composition of claim 1 , wherein the perfume composition further comprises a third perfume accord comprising perfuming compounds dominated by a third olfactive note, wherein the third perfume accord is present in the perfume composition in an amount sufficient for the third olfactive note to be perceived by a subject at a third time.

5. The perfume composition of claim 4 , wherein the third time is after the second time.

6. The perfume composition of claim 4 , wherein the third perfume accord comprises perfuming compounds having a volatility ranging from 49 to 0.1 μg/l in air.

7. The perfume composition of claim 1 , wherein the sufficient amount of the first perfume accord is from 30% to 70% by weight of the perfume composition.

8. The perfume composition of claim 1 , wherein the sufficient amount of the second perfume accord is from 30% to 70% by weight of the perfume composition.

9. The perfume composition of claim 4 , wherein the sufficient amount of the third perfume accord is from 30% to 70% by weight of the perfume composition.

10. The perfume composition of claim 1 , wherein the first perfume accord and the second perfume accord are present in the perfume composition at a weight ratio of 1:1.

11. The perfume composition of claim 4 , wherein the first perfume accord, the second perfume accord, and the third perfume accord are present in the perfume composition at a weight ratio of 1:1:1.

12. The perfume composition of claim 1 , wherein the perception of the second olfactive note is at a level sufficient to reduce, prevent, or suppress a reduced perception of the perfume composition by the subject over time.

13. The perfume composition of claim 4 , wherein the perception of the first olfactive note, the second olfactive note, and the third olfactive note is at a level sufficient to reduce, prevent, or suppress a reduced perception of the perfume composition by the subject over time.

14. The perfume composition of claim 1 , wherein the second perfume accord further comprises a mixture comprising the second perfume accord encapsulated within a second matrix material.

15. The perfume composition of claim 4 , wherein the third perfume accord further comprises a mixture comprising the third perfume accord encapsulated within a third matrix material.
