Said nitriles are capable already in amounts below 5 wt.-percent to modulate, intensify and/or increase the long-lasting effect of said secondary fragrances.

Description

Fragrance mixtures comprising aromatic nitriles

AREA OF INVENTION

[0001] The present refers to the area of fragrances and concerns fragrance mixtures comprising aromatic nitriles with improved scent notes.

BACKGROUND OF THE INVENTION

[0002] On the part of perfumery, there is a great demand for fragrances, especially notes, which allow an expansion of the perfumery palette. The demand is particularly high for fragrances which, in small doses, have a great effect on other fragrances and change them for the better, for example in terms scent recognition ("modulation"), intensity and long-lasting effect.

RELEVANT PRIOR ART

[0003] Aromatic nitriles are well known synthetic intermediates for both the chemical industry [see March's Advanced Organic Chemistry, Reactions, Mechanisms and Structure, John Wiley and Sons, Inc., New York, 2007], and the perfume industry.

[0004] A suitable process for obtaining aromatic nitriles encompasses the use of cyanide sources such as for example CuCN, KCN, NaCN, Zn(CN)2, TMSCN or in the transformation of arylhalogenides into nitriles [see Kim et al., Angewandte Chemie, Vol. 124, p 12114 ff (2012)].

[0005] EP 0550762 Al (KAO) refers to a process for producing a nitrile by heating an aldoxime in the presence of one or more catalysts selected from hydroxides of alkali metals, alcoholates of alkali metals, hydroxides of alkaline earth metals and alcoholates of alkaline earth metals, and distilling off water formed in the course of the reaction from the reaction system.

[0006] EP 2979682 A1 (SYMRISE) claims fragrance compositions comprising aromatic nitriles such as for example 3,4-dimethyl benzonitrile in combination with specific solvents.

OBJECT OF THE INVENTION

[0007] Therefore, it has been the object of the present invention providing new fragrance mixtures, showing improvements in performance. Desired are in particular primary fragrances i which are capable of modulating, intensifying and increasing the long-lasting effect of other secondary fragrances in small amount, preferably in amount below 5 wt.-percent, more preferably less than 3 wt.-percent and most preferably less than 0.5 wt.-percent.

BRIEF DESCRIPTION OF THE INVENTION

[0008] A first object of the present invention refers to a fragrance mixture comprising or consisting of

(a) at least one a primary fragrance according to general formula (I) wherein R¹, R², R³, R⁴, and R⁵ independently of one another represent hydrogen or linear or branched Ci-Cio-alkyl, which is optionally substituted with hydroxy or Ci -C4-alkyl or linear or branched Ci-Cio-alkoxy, which is optionally substituted with hydroxy or Ci- C4-alkyl,

(b) at least one secondary fragrance different from component (a) and optionally

(c) at least one solvent, wherein said at least one secondary fragrance belongs to the group of fragrances exhibiting at least one of the following scent notes: fruity; woody; floral; aromatic/herbal; citrus; spicy; and green. [0009] Surprisingly, it has been observed, that aromatic nitriles in general, more particular certain benzonitriles, in particular 3,4-dimethyl benzonitrile are capable to improve the olfactory profile of a number of defined secondary fragrances. In particular, the nitriles are able to provide to said secondary fragrances more volume, body, richness and complexity. They add notes like, orange, mango, hyacinth and/or pepper an enhance spiciness and balsamic and sandal notes. This is even more surprising, since the nitriles themselves show a strong cinnamon note. Moreover, the nitriles improve the long-lasting effect of the secondary fragrances, in particular in the presence of specific solvents.

[0010] With regard to the specific scent categories the following perfuming effects are achieved:

Aromatic nitriles

[0011] The aromatic nitriles forming component (a) and hereinafter forming the of "primary fragrances" represent known compounds, which are obtainable according to standard procedures of organic chemistry. Reference is made for example to applicant's earlier application EP 2979682 A1. In a preferred embodiment the compositions according to the invention comprise as component (a) aromatic nitriles according to formula (II) wherein R², R³ independently of one another represent hydrogen or linear or branched Ci- Cw-alkyl, which is optionally substituted with hydroxy or Ci -C4-a Ikyl or linear or branched Ci- C -alkoxy, which is optionally substituted with hydroxy or Ci -C4-alkyl.

[0012] More preferably the compositions according to the invention include aromatic nitriles according to formula, wherein the R² and R³ substituents of the aromatic nitrile represent methyl.

[0013] Examples of suitable aromatic nitriles forming component (a) encompass the following species:

• 3,4-dimethyl benzonitrile;

• 4-(2-methylpropyl) benzonitrile;

• 3-methyl benzonitrile;

• 2-methoxy benzonitrile;

• 3,4-dimethoxy benzonitrile;

• 4-methoxybenzonitrile and mixtures thereof.

[0014] The most preferred compound is 3,4-dimethyl benzonitrile, available from Symrise AG.

Secondary fragrances

[0015] As explained above, the secondary fragrances may belong to one, two or more of the following scent categories, as they are common and standard in perfume industry: fruity; woody; floral; aromatic/herbal; citrus; spicy; and green.

[0016] In other words, the fragrances belonging to one of the groups share the same olfactory sensation. The following Tables A to G provide examples for each of these categories, without claiming to be complete. Table A

Binary, ternary and multiple fragrance mixtures

[0017] While the mixtures according to the present invention may include 1, 2, 3, 4, 5 or even more secondary fragrances from the list provided above, binary and ternary combinations are preferred.

[0018] Therefore, a first preferred embodiment refers to binary mixtures of components (a) and (b.)
