CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a U.S. National Phase Application of International Patent Application No. PCT/EP2019/066638, filed Jun. 24, 2019, which claims the benefit of priority to European Patent Application No. 18179844.8, filed Jun. 26, 2018, the entire contents of each of which are hereby incorporated by reference herein.

TECHNICAL FIELD

The present invention relates to the field of perfumery. More particularly, the present invention relates to the use as perfuming ingredient of compounds of formula (I) as defined below, which are particularly useful perfuming ingredients of the floral type. Moreover, the present invention relates to a perfuming composition or a perfumed consumer product comprising the compounds of formula (I).

BACKGROUND

One of the key ingredients in the perfumery industry are the one imparting a floral impression and in particular a lily of the valley odor. Said note is very appreciated and used in a multitude of perfumed consumer products. Lilial® (2-methyl-3-[4-(2-methyl-2-propanyl)phenyl]propanal, trademark from Givaudan-Roure SA, Vernier, Suisse) and Lyral® (4/3-(4-hydroxy-4-methylpentyl)-3-cyclohexene-1-carbaldehyde; origin International Flavors & Fragrances, USA) are both common ingredients used for this purpose. Lilial® possesses a lily of the valley odor with watery connotations while Lyral® imparts floral, lily of the valley, hydroxycitronellal odor notes quite different from the notes of Lilial®. However, both ingredients have been limited due to various reasons.

So, there is a constant need to develop novel perfuming ingredients imparting floral and in particular lily of valley notes.

One related structural analogue of compound of formula (I) has been reported in WO 2017009175 as a perfuming ingredient characterized by having a nice and well balanced floral, lily of the valley, hydroxycitronellal odor note, and an overall olfactive character strongly reminiscent of the one of the very well-known ingredients, Lyral®. Said analogue being 3-[4-(2-hydroxy-2-methylpropyl)phenyl]propanal possesses an aromatic phenyl moiety i.e. a different chemical structure from the present invention's compound.

The prior art document does not report the compound of formula (I) nor suggest any organoleptic properties of such compound of formula (I), or any use of said compounds in the field of perfumery.

SUMMARY OF THE INVENTION

The invention relates to compound of formula (I) which imparts an odor of the floral type, in particular lily of the valley (also named muguet) which is much appreciated in perfumery.

A first object of the present invention is a compound of formula


in the form of any one of its stereoisomers, regioisomers or a mixture thereof.

A second object of the present invention is 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 said composition or article an effective amount of at least a compound of formula (I) as defined above.

A third object of the present invention is the use as a perfuming ingredient of a compound of formula (I) as defined above.

Another object of the present invention is a perfuming composition comprisingi) at least one compound of formula (I), as defined above;ii) at least one ingredient selected from the group consisting of a perfumery carrier and a perfumery base; andiii) optionally at least one perfumery adjuvant.

A last object of the present invention is a perfumed consumer product comprising at least one compound of formula (I) or a composition as defined above.
