Abstract

The present invention provides a method of using, as a fragrance component, a compound that is excellent in fragrance retention and that has green floral and fruity like odors, which are useful as fragrances, and a fragrance composition with sweetness and voluminousness containing the compound. The present invention relates to a fragrance composition containing 2-n-pentyl cyclopentanone oxime and a method of using 2-n-pentyl cyclopentanone oxime as a fragrance component.

First claim

The invention claimed is:

1. A method of imparting a fragrance to a fragrance composition, a cleanser composition, a fabric treatment composition, or a cosmetic, said method comprising adding 2-n-pentyl cyclopentanone oxime to said fragrance composition, cleanser composition, fabric treatment composition, or cosmetic.

2. A method according to claim 1 , wherein said fragrance composition, cleanser composition, fabric treatment composition, or cosmetic comprises 2-n-pentyl cyclopentanone oxime in an amount of 0.01 to 99 mass % with respect to the total mass of the fragrance composition, cleanser composition, fabric treatment composition, or cosmetic.

3. A method according to claim 1 , wherein said fragrance composition, cleanser composition, fabric treatment composition, or a cosmetic comprises 2-n-pentyl cyclopentanone oxime in an amount of 0.1 to 50 mass % with respect to the total mass of the fragrance composition, cleanser composition, fabric treatment composition, or cosmetic.

4. A method according to claim 1 , wherein the fragrance composition, cleanser composition, fabric treatment composition, or a cosmetic comprises another compound capable of imparting fragrance other than 2-n-pentyl cyclopentanone oxime.

5. A fragrance composition comprising 2-n-pentyl cyclopentanone oxime and another fragrance compound in addition to the 2-n-pentyl cyclopentanone oxime.

6. A fragrance composition according to claim 5 , further comprising an oil.

7. A fragrance composition according to claim 6 , wherein said oil present in the fragrance composition is present in an amount of from 0.01 to 95 mass %.

8. A fragrance composition according to claim 6 , wherein said oil present in the fragrance composition is present in an amount of from 1 to 90 mass %.

9. A fragrance composition according to claim 5 , wherein said another fragrance compound comprises at least one member selected from the group consisting of a hydrocarbon, an alcohol, a phenol, an aldehyde, a ketone, an acetal, an ether, an ester, a carbonate, a lactone, an oxime, a nitriles, a Schiff base, an amide, a nitrogen-containing compound, a sulfur-containing compound, a natural essential oil, and a natural extract.

10. A fragrance composition according to claim 5 , wherein said another fragrance compound comprises at least one member selected from the group consisting of a fragrance having respective fragrance notes of a citrus tone, a floral tone, a fruity tone, a herbal tone, a spicy tone, a green tone, a woody tone, a balsamic tone, an aldehydic tone, a minty tone, an aromatic tone, an earthy tone, a mossy tone, a honey tone, a leather tone, an animalic tone, an amber tone, and a musky tone.

12. A method according to claim 11 , wherein said cleanser composition is a skin cleanser composition.

13. A method according to claim 11 , wherein said cleanser composition is a hair cleanser composition.

14. A method according to claim 1 , wherein said method imparts a fragrance to a fabric treatment composition.

15. A method according to claim 14 , wherein said fabric treatment composition is a softener composition.

16. A method according to claim 1 , wherein said method imparts a fragrance to a cosmetic.

17. A method of producing a fragrance composition comprising 2-n-pentyl cyclopentanone oxime,
the method comprising:
oximating 2-n-pentyl cyclopentanone to provide 2-n-pentyl cyclopentanone oxime, and
mixing at least one of an oil and another fragrance compound other than 2-n-pentyl cyclopentanone oxime with 2-n-pentyl cyclopentanone oxime.

18. A method according to claim 17 , wherein a solvent is present during said oximating.

19. A method according to claim 18 , wherein said oximating is carried out by mixing 2-n-pentyl cyclopentanone and hydroxylamine or an inorganic acid salt thereof, and the amount of the solvent is 0.5 to 10 times by mass with respect to the hydroxylamine or inorganic acid salt thereof.

20. A method according to claim 18 , wherein said oximating is carried out by mixing 2-n-pentyl cyclopentanone and hydroxylamine or an inorganic acid salt thereof, and the amount of the solvent is 0.1 to 5 times by mass with respect to the 2-n-pentyl cyclopentanone.
