Abstract

Fragrance compounds having a unique chemical structure are provided, including esters and ethers of 3-cyclohexenyl methanol and derivatives thereof. The fragrance compounds can have multi-faceted odors. The fragrance compounds can be used alone or incorporated into a fragrance composition and/or consumer product to modify or enhance the odor of the fragrance composition and/or consumer product.

First claim

What is claimed is:

1. A fragrance composition comprising a fragrance compound of Formula I, or a stereoisomer thereof:

wherein
R is C(O)R b ;
and
R b is selected from CH(OH)CH 3 , CH 2 (CO)CH 3 , and CH 2 OH.

2. The fragrance composition of claim 1 , wherein the fragrance compound is selected from the group consisting of:
cyclohex-3-en-1-ylmethyl 2-hydroxypropanoate;
cyclohex-3-en-1-ylmethyl 3-oxobutanoate;
cyclohex-3-en-1-ylmethyl 2-hydroxyacetate;
stereoisomers thereof; and
combinations thereof.

3. The fragrance composition of claim 1 , wherein the fragrance compound is cyclohex-3-en-1-ylmethyl 2-hydroxypropanoate.

4. The fragrance composition of claim 3 , wherein the fragrance composition is cyclohex-3-en-1-ylmethyl (2S)-2-hydroxypropanoate.

5. The fragrance composition of claim 1 , further comprising an additional fragrance compound selected from an aldehydic compound, a balsamic compound, a citrus compound, a floral compound, a fruity compound, a gourmand compound, a marine compound, a mossy compound, a musk compound, a piney compound, a powdery compound, a woody compound, and combinations thereof.

6. The fragrance composition of claim 1 , further comprising a solvent.

7. A method of modifying the odor properties of a fragrance composition by adding to the fragrance composition an olfactory effective quantity of a fragrance compound of Formula I, or a stereoisomer thereof:

wherein
R is C(O)R b ;
and
R b is selected from CH(OH)CH 3 , CH 2 (CO)CH 3 , and CH 2 OH.

8. The method of claim 7 , wherein the fragrance compound is cyclohex-3-en-1-ylmethyl 2-hydroxypropanoate.

9. The fragrance composition of claim 8 , wherein the fragrance composition is cyclohex-3-en-1-ylmethyl (2S)-2-hydroxypropanoate.

10. A consumer product, comprising a consumer product base and a fragrance compound of Formula I, or a stereoisomer thereof:

wherein
R is C(O)R b ;
and
R b is selected from CH(OH)CH 3 , CH 2 (CO)CH 3 , and CH 2 OH.

11. The consumer product of claim 10 , wherein the fragrance compound is selected from the group consisting of:
cyclohex-3-en-1-ylmethyl 2-hydroxypropanoate;
cyclohex-3-en-1-ylmethyl 3-oxobutanoate;
cyclohex-3-en-1-ylmethyl 2-hydroxyacetate;
stereoisomers thereof; and
combinations thereof.

12. The consumer product of claim 11 , wherein the fragrance compound is cyclohex-3-en-1-ylmethyl 2-hydroxypropanoate.

13. The fragrance composition of claim 12 , wherein the fragrance composition is cyclohex-3-en-1-ylmethyl (2S)-2-hydroxypropanoate.

14. The consumer product of claim 10 , wherein the consumer product is selected from a fine fragrance, a personal care product, a home care product, and an air care product.

15. The consumer product of claim 14 , wherein the fine fragrance is selected from parfum, extrait de parfum, eau de parfum, millesime, parfum de toilette, eau de toilette, eau de cologne, body splash, after shave, body mists, and baby colognes.

16. The consumer product of claim 14 , wherein the personal care product is selected from lotions, creams, moisturizers, body washes, hand soaps, shampoos, conditioners, and soaps.

17. The consumer product of claim 14 , wherein the home care product is selected from fabric conditioner, fabric softener, laundry detergent, laundry additive, rinse additive, bleach, dryer sheets, perfume beads, car care products, dishwashing detergent, and hard surface cleaners.

18. The consumer product of claim 14 , wherein the air care product is selected from a candle, aerosol, air freshener, liquid electric air freshener, fragrance diffuser, gel air freshener, plug-in air freshener, plug-in oil, and wax melt.

19. A method of modifying the odor properties of a consumer product by adding to a consumer product base an olfactory effective quantity of a fragrance compound of Formula I, or a stereoisomer thereof:

wherein
R is C(O)R b ;
and
R b is selected from CH(OH)CH 3 , CH 2 (CO)CH 3 , and CH 2 OH.

20. A method of manufacturing a consumer product, comprising:
admixing a fragrance compound of Formula I, or a stereoisomer thereof:

wherein
R is C(O)R b ;
and
R b is selected from CH(OH)CH 3 , CH 2 (CO)CH 3 , and CH 2 OH,
with a consumer product base.

21. The method of claim 20 , wherein the fragrance compound is incorporated into a fragrance composition prior to admixing with the consumer product base.

22. A fragrance compound, selected from the group consisting of:
cyclohex-3-en-1-ylmethyl 2-hydroxypropanoate;
cyclohex-3-en-1-ylmethyl 3-oxobutanoate;
cyclohex-3-en-1-ylmethyl 2-hydroxyacetate;
and
stereoisomers thereof.
