Abstract

A fragrance composition is described which comprises: at least two different fragrance accords wherein at least 30 wt % of each fragrance accord comprises the key contributor(s) of said fragrance accord and wherein the average of the odor detection thresholds of said key contributor(s) for each fragrance accord is within the same order of magnitude as the average of the odor detection thresholds of the key contributor(s) for said other fragrance accord(s); and wherein the base note(s) of each fragrance accord comprises less than 15% of the notes of said accord. Methods of manufacture thereof together with methods of attenuating fragrance habituation are also described.

First claim

The invention claimed is:

1. A fragrance composition comprising: at least two different fragrance accords wherein at least 30 wt % of each fragrance accord comprises a key contributor(s) of said fragrance accord, wherein the key contributor(s) have an odour detection threshold, and wherein the average of the odour detection thresholds of said key contributor(s) for each fragrance accord is within the same order of magnitude as the average of the odour detection thresholds of the key contributor(s) for said other fragrance accord(s).

2. The composition according to claim 1 , wherein the fragrance composition is provided with at least three fragrance accords.

3. The composition according to claim 1 , wherein the fragrance composition is provided with between two to five fragrance accords.

4. The composition according to claim 1 , wherein the fragrance composition is provided with three fragrance accords.

5. The composition according to claim 1 , wherein the base note(s) of the fragrance accords comprise less than 15 wt % of the notes of said accord.

6. The composition according to claim 1 , wherein the base note(s) of the fragrance accords comprise less than 12.5 wt % of the notes of said accord.

7. The composition according to claim 1 , wherein the base note(s) of the fragrance accords comprise less than 10 wt % of the notes of said accord.

8. The composition according to claim 1 , wherein the base note(s) of the fragrance accords comprise substantially 7.5 wt %+/−1.5 wt % of the notes of said accord.

9. The composition according to claim 1 , wherein the middle note(s) of the fragrance accords comprise greater than 30 wt % of the notes of said accord and the top note(s) of the fragrance accords comprise greater than 30 wt % of the notes of said accord, wherein the % of notes of the overall accord equals 100 wt %.

10. The composition according to claim 1 , wherein the middle note(s) of the fragrance accords comprise greater than 40 wt % of the notes of said accord and the top note(s) of the fragrance accords comprise greater than 40 wt % of the notes of said accord, wherein the % of notes of the overall accord equals 100 wt %.

11. The composition according to claim 1 , wherein an odour slope of each fragrance accord expressed graphically with intensity on the y-axis (1-10) and concentration on the x-axis (μg/L) in the fragrance composition has a similar gradient wherein a similar gradient is understood to mean gradients within 50 wt % of each other.

12. The composition according to claim 1 , wherein each fragrance accord in the fragrance composition of the present invention may comprise of between 5-49.9% wt of the composition.

13. The composition according to claim 1 , wherein the fragrance compositions of the present invention may comprise between 1-90% wt of technical accords.

14. The composition according to claim 1 , wherein the fragrance composition comprises between 0-10% wt of MOC accords.

15. The composition according to claim 1 , wherein a backbone is provided in the composition, wherein said backbone comprises at least one of: odiferous materials; bulk carriers and/or solvents.

16. A method of making a fragrance composition having at least two different fragrance accords comprising the steps of: matching said at least two different fragrance accords by providing that at least 30% wt of a key contributor(s) of each fragrance accord has an average odour detection threshold within the same order of magnitude as the average of the odour detection thresholds of the key contributor(s) of each other fragrance accord.

17. The method according to claim 16 , wherein the fragrance composition is provided with at least three fragrance accords.

18. The method according to claim 16 , wherein the fragrance composition is provided with between two to five fragrance accords.

19. The method according to claim 16 , wherein the fragrance composition is provided with three fragrance accords.

20. The method according to claim 16 , wherein the base note(s) of the fragrance accords comprise less than 15 wt % of the notes of said accord.

21. The method according to claim 16 , wherein the base note(s) of the fragrance accords comprise less than 12.5 wt % of the notes of said accord.

22. The method according to claim 16 , wherein the base note(s) of the fragrance accords comprise less than 10 wt % of the notes of said accord.

23. The method according to claim 16 , wherein the base note(s) of the fragrance accords comprise substantially 7.5 wt %+/−1.5 wt % of the notes of said accord.

24. The method according to claim 16 , wherein the middle note(s) of the fragrance accords comprise greater than 30 wt % of the notes of said accord and the top note(s) of the fragrance accords comprise greater than 30 wt % of the notes of said accord, wherein the % of notes of the overall accord equals 100 wt %.

25. The method according to claim 16 , wherein the middle note(s) of the fragrance accords comprise greater than 40 wt % of the notes of said accord and the top note(s) of the fragrance accords comprise greater than 40 wt % of the notes of said accord, wherein the % of notes of the overall accord equals 100 wt %.

26. The method according to claim 16 , wherein an odour slope of each fragrance accord expressed graphically with intensity on the y-axis (1-10) and concentration on the x-axis (μg/L) in the fragrance composition has a similar gradient wherein a similar gradient is understood to mean gradients within 50 wt % of each other.

27. The method according to claim 16 , wherein each fragrance accord in the fragrance composition of the present invention may comprise of between 5-49.9% wt of the composition.

28. The method according to claim 16 , wherein the fragrance compositions of the present invention may comprise between 1-90% wt of technical accords.

29. The method according to claim 16 , wherein the fragrance composition comprises between 0-10% wt of MOC accords.

30. The method according to claim 16 , wherein a backbone is provided in the composition, wherein said backbone comprises at least one of: odiferous materials; bulk carriers and/or solvents.

31. A method of attenuating fragrance habituation comprising the steps of emanating a fragrance composition comprising at least two different fragrance accords and wherein said fragrance composition comprises: at least two different fragrance accords wherein at least 30 wt % of each fragrance accord comprises a key contributor(s) of said fragrance accord, wherein the key contributor(s) have an odour detection threshold, and wherein the average of the odour detection thresholds of said key contributor(s) for each fragrance accord is within the same order of magnitude as the average of the odour detection thresholds of the key contributor(s) for said other fragrance accord(s).

32. The method according to claim 31 , wherein the fragrance composition is provided with at least three fragrance accords.

33. The method according to claim 31 , wherein the fragrance composition is provided with between two to five fragrance accords.

34. The method according to claim 31 , wherein the fragrance composition is provided with three fragrance accords.

35. The method according to claim 31 , wherein the base note(s) of the fragrance
