Abstract

The present invention relates to novel compounds and their use as fragrance materials.

First claim

What is claimed is:

1. A compound, wherein the compound has formula II:

and wherein R′ is a C 6 linear or branched alkyl or alkenyl group.

2. The compound of claim 1 , wherein the compound is selected from the group consisting of (Z)-((hex-3-en-1-yloxy)methyl)cyclopropane, (E)-((hex-3-en-1-yloxy) methyl)cyclopropane and ((hexyloxy)methyl)cyclopropane.

3. A fragrance formulation of comprising an olfactory acceptable amount of a compound, wherein the compound has formula II:

and wherein R′ is a C 6 linear or branched alkyl or alkenyl group.

4. The fragrance formulation of claim 3 , wherein the compound is selected from the group consisting of (Z)-((hex-3-en-1-yloxy)methyl)cyclopropane, (E)-((hex-3-en-1-yloxy) methyl)cyclopropane and ((hexyloxy)methyl)cyclopropane.

5. The fragrance formulation of claim 3 , wherein the olfactory acceptable amount is from about 0.005 to about 50 weight percent of the fragrance formulation.

6. The fragrance formulation of claim 3 , wherein the olfactory acceptable amount is from about 0.5 to about 25 weight percent of the fragrance formulation.

7. The fragrance formulation of claim 3 , wherein the olfactory acceptable amount is from about 1 to about 10 weight percent of the fragrance formulation.

8. The fragrance formulation of claim 3 further comprising a polymer.

9. The fragrance formulation of claim 8 , wherein the polymer is selected from the group consisting of polyacrylate, polyurea, polyurethane, polyacrylamide, polyester, polyether, polyamide, poly(acrylate-co-acrylamide), starch, silica, gelatin and gum Arabic, alginate, chitosan, polylactide, poly(melamine-formaldehyde), poly(urea-formaldehyde) and a combination thereof.

10. A method of improving, enhancing or modifying a fragrance formulation comprising the step of adding to the fragrance formulation an olfactory acceptable amount of a compound, wherein the compound has formula II

and wherein R′ is a C 6 linear or branched alkyl or alkenyl group.

11. The method of claim 10 , wherein the compound is selected from the group consisting of (Z)-((hex-3-en-l-yloxy)methyl)cyclopropane, (E)-((hex-3-en-1-yloxy) methyl)cyclopropane and ((hexyloxy)methyl)cyclopropane.

12. A fragrance product containing the compound of claim 1 .

13. The fragrance product of claim 12 , wherein the fragrance product is selected from the group consisting of a perfume, a cologne, toilet water, a cosmetic product, a personal care product, a fabric care product, a cleaning product and an air freshener, a bar soap, a liquid soap, a shower gel, a foam bath, a cosmetic, a skin care product, a hair care product, a deodorant, an antiperspirant, a feminine care product, a baby care product, a family care product, a fabric product, an air care product, a fragrance delivery system, a cosmetic preparation, a cleaning agent, a disinfectant, a washing agent, a dental and oral hygiene product, a health care and nutritional product and a food product.
