Abstract

The present invention relates to phenylpropanal derivatives of formula (I)

in the form of any one of its stereoisomers or a mixture thereof, and wherein the dotted line represents a carbon-carbon single or double bond; X represents a CN or CHO group; each R 1 , R 2 and R 3 independently from each other, represents a hydrogen atom or a C 1-2 alkyl group; and R represents a group of formula —[CH 2 ] n C(Me) 2 OH, wherein n is 1 or 2; said R being a meta or para substituent of the aromatic ring, relative position 1;

and their uses as perfuming ingredients as well as the composition and consumer product including such derivatives.

First claim

1 . A compound of formula

in the form of any one of its stereoisomers or a mixture thereof, and wherein
the dotted line represents a carbon-carbon single or double bond;
X represents a CN or CHO group;
each R 1 , R 2 and R 3 independently from each other, represents a hydrogen atom or a C 1-2 alkyl group; and
R represents a group of formula —[CH 2 ] n C(Me) 2 OH, wherein n is 1 or 2; said R being a meta or para substituent of the aromatic ring, relative position 1.

2 . A compound according to claim 1 , wherein the compound comprises formula

in the form of any one of its stereoisomers or a mixture thereof, and wherein
the dotted line represents a carbon-carbon single or double bond;
n is 1 or 2;
X represents a CN or CHO group; and
and each R 1 , R 2 and R 3 independently from each other, represents a hydrogen atom or a C 1-2 alkyl group.

3 . A compound according to claim 1 , wherein the compound comprises formula

wherein n, R 1 , R 2 and R 3 are as defined in claim 1 .

4 . A compound according to claim 1 , characterized in that n is 1.

5 . A compound according to claim 1 , characterized in that one or two of said R 1 , R 2 and R 3 may represent a hydrogen atom, and the other or others a methyl group.

6 . A compound according to claim 1 , wherein the compound is 3-[4-(2-hydroxy-2-methylpropyl)phenyl]propanal.

7 . The compound of formula (I) of claim 1 , wherein the compound is a perfuming ingredient.

8 . A perfuming composition comprising
i) at least one compound of formula (I) of 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.

9 . A perfuming consumer product comprising at least one compound of formula (I) of claim 1 .

10 . A perfuming consumer product according to claim 9 , characterized in that the perfumery consumer product is a perfume, a fabric care product, a body-care product, a cosmetic preparation, a skin-care product, an air care product or a home care product.

11 . A perfuming consumer product according to claim 9 , characterized in that the perfumery consumer product is a fine perfume, a splash or eau de perfume, a cologne, an shave or after-shave lotion, a liquid or solid detergent, a fabric softener, a fabric refresher, an ironing water, a paper, a bleach, a carpet cleaners, curtain-care products a shampoo, a coloring preparation, a color care product, a hair shaping product, a dental care product, a disinfectant, an intimate care product, a hair spray, a vanishing cream, a deodorant or antiperspirant, hair remover, tanning or sun product, nail products, skin cleansing, a makeup, a perfumed soap, shower or bath mousse, oil or gel, or a foot/hand care products, a hygiene product, an air freshener, a “ready to use” powdered air freshener, a mold remover, furnisher care, wipe, a dish detergent or hard-surface detergent, a leather care product, a car care product.
