Abstract
The present invention relates to the use as perfuming ingredient, in particular to confer odor notes of the violet, violet leaves type, of a compound of formula (I), wherein n represents 1 or 2, A represents CH2 or CO; and R represents a C1-4 alkyl or alkenyl group or a C3 cycloalkyl group, or when A is a CH2 group R may also represent a C1-3 acyl group. Moreover, following what is mentioned herein, the present invention comprises the invention's compound as part of a perfuming composition or of a perfuming consumer product.
Claims18
A perfuming composition comprising
- i) at least one compound of formula
- wherein n represents 1 or 2;
- A represents CH2 or CO;
- and
- R represents a C1-4 alkyl group, a C1-4 alkenyl group or a C3 cycloalkyl group, or when A is a CH2 group, R may also represent a C1-3 acyl group,
- 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;
- wherein the compound confers, enhances, improves or modifies violet or violet leaves odor notes of the perfuming composition.
A perfuming consumer product comprising:
- i) at least one compound of formula
- wherein n represents 1 or 2;
- A represents CH2 or CO;
- and
- R represents a C1-4 alkyl group, a C1-4 alkenyl group or a C3 cycloalkyl group, or when A is a CH2 group, R may also represent a C1-3 acyl group, and
- ii) a perfumery consumer base, wherein the compound confers, enhances, improves or modifies violet or violet leaves odor notes of the perfuming consumer product.
A method to confer, enhance, improve or modify violet or violet leaves odor notes of a perfuming composition that includes a perfume carrier or a perfume base or of a perfumed article, which method comprises adding to said composition or article an effective amount of a perfuming ingredient that is at least a compound of formula:
- wherein n represents 1 or 2;
- A represents CH2 or CO;
- and
- R represents a C1-4 alkyl group, a C1-4 alkenyl group or a C3 cycloalkyl group, or when A is a CH2 group, R may also represent a C1-3 acyl group;
- wherein, in the compound of formula (I), methyl oct-7-en-4-ynoate and 7-ethoxyhept-1-en-4-yne are excluded.
A method to confer, enhance, improve or modify violet or violet leaves odor notes of a perfuming composition that includes a perfume carrier or a perfume base or of a perfumed article, which method comprises adding to said composition or article an effective amount of a perfuming ingredient that is at least a compound of 8-propoxyoct-1-en-4-yne, 8-methoxyoct-1-en-4-yne or 7-(allyloxy)hept-1-en-4-yne.
