Abstract

The present invention relates to the field of perfumery and concerns the use as perfuming ingredient of ketones of formula wherein n represents 0, 1 or 2, m represents 0, 1 or 2, the dotted lines represent only single bonds or one double bond and two single bonds, R 1 represents a hydrogen atom or a methyl or ethyl group, said R 1 group being located at any of the position of the cyclic moiety, R 2 represents a C 1 -C 3 O-alkyl or O-alkenyl group or a substituted or unsubstituted ethylene or cyclopropyl group. Said compounds are useful to impart a clean and natural fruity, pineapple odor type. The present invention concerns also the compositions or articles containing said compounds (I) as well as some of said compounds (I).

First claim

What is claimed is:

1. A compound of formula

wherein one dotted line represents a single or double carbon-carbon bond and the two other dotted lines represent a single carbon-carbon bond;
R 1 represents a hydrogen atom or a methyl group, the R 1 group being located at any of the position of the cyclic moiety;
R 4 representing, simultaneously or independently from each other, a hydrogen atom or a methyl group.

2. 1-(1-cyclohex-1-enyl)-5-hexen-2-one.

3. A method to confer, enhance, improve or modify the odor properties of a perfuming composition or of a perfumed article, which method comprises adding to the composition or article an effective amount of at least a compound of claim 1 .

4. The method according to claim 3 , wherein at least one R 4 is a hydrogen atom and R 1 represents a hydrogen atom.

5. The method according to claim 3 , wherein the compound is 1-cyclohexyl-5-hexen-2-one or 1-(1-cyclohex-1-enyl)-5-hexen-2-one.

6. A perfuming ingredient in the form of a composition comprising
i) at least one compound of formula (IV) as defined in claim 1 ;
ii) at least one ingredient selected from the group consisting of a perfumery carrier and a perfumery base; and
iii) optionally at least one perfumery adjuvant.

7. A perfuming ingredient in the form of a composition comprising
i) a compound as defined in claim 2 ;
ii) at least one ingredient selected from the group consisting of a perfumery carrier and a perfumery base; and
iii) optionally at least one perfumery adjuvant.

8. A perfumed article comprising:
i) at least one compound of formula (IV), as defined in claim 1 ; and
ii) a consumer product base.

9. A perfumed article according to claim 8 , wherein the consumer product base is a solid or liquid detergent, a fabric softener, a perfume, a cologne or after-shave lotion, a perfumed soap, a shower or bath salt, mousse, oil or gel, a hygiene product, a hair care product, a shampoo, a body-care product, a deodorant or antiperspirant, an air freshener, a cosmetic preparation, a fabric refresher, an ironing water, a paper, a wipe or a bleach.

10. A perfumed article comprising:
i) a compound as defined in claim 2 ; and
ii) a consumer product base.

11. A perfumed article according to claim 10 , wherein the consumer product base is a solid or liquid detergent, a fabric softener, a perfume, a cologne or after-shave lotion, a perfumed soap, a shower or bath salt, mousse, oil or gel, a hygiene product, a hair care product, a shampoo, a body-care product, a deodorant or antiperspirant, an air freshener, a cosmetic preparation, a fabric refresher, an ironing water, a paper, a wipe or a bleach.

12. The compound of claim 1 wherein R 1 is hydrogen.

13. The compound of claim 1 wherein each R 4 is hydrogen.
