Abstract

Perfumed compositions include, as an odorant therefor, an olfactory affecting amount of N,N-diethyl-2-ethylhexanamide.

Description

La présente invention a pour objet un procédé d'obtention de compositions parfumantes et de produits parfumés et les compositions et produits ainsi obtenus.The subject of the present invention is a process for obtaining perfume compositions and perfumed products and the compositions and products thus obtained.

On a déjà proposé l'utilisation de quelques amides d'acides alcanoïques en parfumerie ou dans des compositions répulsives contre les insectes, mais aucun de ces alcanamides ne s'est signalé par des propriétés olfactives originales. Ainsi, EINHORN et al., Ber. 39 1223 (1906) ont rapporté que la N,N-diéthyl éthyl-2 butanamide possède une faible odeur rappelant celle du menthol ; dans le brevet français 1 572 332 on a indiqué que la N,N-diéthyl diméthyl propanamide présente une fragrance de menthe poivrée alors que la N,N-diméthyl éthyl-2 butanamide exhale une senteur de menthe naturelle. Dans le brevet américain 3 909 462 on a attribué à la N-phényl N-méthyl éthyl-2 butanamide une note pamplemousse, recherchée pour l'obtention d'arômes alimentaires, et herbacée rendant ce produit apte à la réalisation de bases pour parfums à note lavande. Enfin A.S. LUTTA et al., Entomol. Obozrenie 45 317-25 (1966) ont noté, dans une étude consacrée aux propriétés répulsives pour les insectes des alcanamides, l'odeur agréable de la N,N-diéthyl octanamide sans toutefois en préciser la note. On a constaté que cette amide possède une note faiblement épicée relativement banale. En définitive, on constate que les amides des acides alcanoïques en C5-C6 possèdent, à l'exception du N-phényl N-méthyl éthyl-2 butanamide, des notes menthées plus ou moins communes. En outre, pour un acide donné le caractère de la note varie suivant la nature des substituants présents sur l'atome d'azote sans que le sens de cette variation puisse être prévisible ; c'est ainsi que la N,N-diméthyl éthyl-2 butanamide présente une note menthe naturelle fraîche plus puissante que la N,N-éthyl amide homologue dont la note bien que menthée est plus faible et poivrée. De son côté la structure de l'acide influence notablement la fragrance de l'amide ; ainsi la N,N'-diéthylcaprylamide présente une note différente de la N,N-diéthyl éthyl-2 butanamide. Il résulte de ce qui précède qu'il est difficile sinon impossible pour l'homme de l'art de prévoir si une alcanamide donnée possédera ou non une odeur agréable du point de vue olfactif et quelle en sera la note.The use of a few amides of alkanoic acids has already been proposed in perfumery or in insect repellants, but none of these alkanamides has been reported by original olfactory properties. Thus, EINHORN et al., Ber. 39 1223 (1906) reported that N, N-diethyl 2-ethyl-butanamide has a weak odor reminiscent of menthol; in French patent 1,572,332 it has been indicated that N, N-diethyl dimethyl propanamide has a peppermint fragrance while N, N-dimethyl 2-ethyl butanamide exhales a scent of natural mint. In US patent 3,909,462, N-phenyl N-methyl-ethyl-2-butanamide has been assigned a grapefruit note, sought for obtaining food flavors, and herbaceous rendering this product suitable for the production of bases for perfumes with lavender note. Finally AS LUTTA et al., Entomol. Obozrenie 45 317-25 (1966) noted, in a study devoted to repellents for insects of alkanamides, the pleasant odor of N, N-diethyl octanamide without however specifying the note. It has been found that this amide has a relatively banal, slightly spicy note. Ultimately, it is found that the amides of C 5 -C 6 alkanoic acids have, with the exception of N-phenyl N-methyl ethyl-2 butanamide, more or less common minty notes. In addition, for a given acid, the character of the note varies according to the nature of the substituents present on the nitrogen atom without the direction of this variation being predictable; N, N-dimethyl-2-butanamide thus has a fresh natural mint note more powerful than the homologous N, N-ethyl amide whose note, although mint is weaker and peppery. For its part, the structure of the acid notably influences the fragrance of the amide; thus N, N'-diethylcaprylamide has a different note from N, N-diethyl ethyl-2 butanamide. he It follows from the above that it is difficult if not impossible for those skilled in the art to predict whether or not a given alkanamide will have a pleasant odor from an olfactory point of view and what the note will be.

L'industrie de la parfumerie est constamment à la recherche de produits qui par l'originalité, le volume et la puissance de leur fragrance puissent conférer aux compositions dans lesquelles ils entrent un caractère tout à fait particulier. La présente invention concerne précisément l'emploi, en parfumerie, d'un tel composé.The perfume industry is constantly looking for products which, through the originality, volume and power of their fragrance, can give the compositions in which they come in a very special character. The present invention relates precisely to the use, in perfumery, of such a compound.

Plus spécifiquement la présente invention a pour objet un procédé pour l'obtention de compositions parfumantes, de.substances parfumées ou de produits finis parfumés caractérisés en ce que l'on ajoute aux constituants usuels de ces compositions, substances ou produits finis, une quantité efficace de N,N-diéthyl éthyl-2 hexanamide.More specifically, the subject of the present invention is a process for obtaining perfume compositions, perfumed substances or perfumed finished products characterized in that an effective amount is added to the usual constituents of these compositions, substances or products of N, N-diethyl ethyl-2 hexanamide.

La présente invention a encore pour objet des compositions parfumantes, produits et substances parfumés caractérisés en ce qu'ils comportent à titre de principe actif ayant une influence sur l'odeur une quantité efficace de N,N-diéthyl éthyl-2 hexanamide.The present invention also relates to perfuming compositions, perfumed products and substances characterized in that they contain, as active principle having an influence on the odor, an effective amount of N, N-diethyl ethyl-2-hexanamide.

Ce produit de formule :

Figure imgb0001
exhale en effet un parfum original associant des notes épine de rose, galbule d'eucaplyptus à une fragrance jasminée légèrement poivrée. Le caractère puissant, diffusif et volumineux de son odeur lui confère un intérêt considérable et unique pour la créaction de compositions pour la parfumerie dans lesquelles il peut être utilisé à titre de seul parfum ou en association avec d'autres composés à notes différentes.This formula product:
Figure imgb0001
 in fact exhales an original fragrance associating notes of rose thorn, eucaplyptus curve with a slightly peppery jasmine fragrance. The powerful, diffusive and voluminous character of its odor gives it a considerable and unique interest in the creation of compositions for perfumery in which it can be used as a single perfume or in combination with other compounds with different notes.

Par "compositions parfumantes", on désigne des mélanges de divers ingrédients tels que solvants, supports solides ou liquides, fixateurs, composés odorants divers, etc..., dans lesquels est incorporée la N,N-diéthyl éthyl-2 hexanamide, lesquels mélanges sont utilisés pour procurer à divers types de produits finis la fragrance recherchée. Les bases pour parfum constituent des exemples préférés de compositions parfumantes dans lesquelles la N,N-diéthyl éthyl-2 hexanamide peut être avantageusement utilisée. Un autre exemple de compositions dans lesquelles ce composé peut être introduit de façon avantageuse, est représenté par les compositions détergentes usuelles. Ces compositions comprennent généralement un ou plusieurs des ingrédients suivants : agents tensioactifs anioniques, cationiques ou amphotères, agents de blanchiment, azurants optiques, charges diverses, agents antiredéposition. La nature de ces divers composants n'est pas critique et la N,N-diéthyl éthyl-2 hexanamide peut être ajoutée à tout type de composition détergente. Les eaux de toilettes, les lotions après rasage, les parfums, les savons ou les produits déodorants par exemple sous forme d'aérosols, constituent des exemples de substances ou de produits finis dans lesquels la N,N-diéthyl éthyl-2 hexanamide apporte sa note originale.By "perfuming compositions" is meant mixtures of various ingredients such as solvents, solid or liquid carriers, fixatives, various odorous compounds, etc., in which N , N -2-ethyl-2-ethylhexanamide is incorporated, which mixtures are used to provide various types of finished products with the desired fragrance. Perfume bases are preferred examples of compositions perfumers in which N, N-diethyl ethyl-2 hexanamide can be advantageously used. Another example of compositions in which this compound can be advantageously introduced, is represented by the usual detergent compositions. These compositions generally comprise one or more of the following ingredients: anionic, cationic or amphoteric surfactants, bleaching agents, optical brighteners, various fillers, anti-redeposition agents. The nature of these various components is not critical and N, N-diethyl ethyl-2 hexanamide can be added to any type of detergent composition. Toilet waters, aftershave lotions, perfumes, soaps or deodorant products, for example in the form of aerosols, constitute examples of substances or finished products in which N, N-diethyl ethyl-2-hexanamide provides original note.

La N,N-diéthyl éthyl-2 hexanamide est un liquide incolore, bouillant à 87°C sous une pression de 1,5 mm de mercure, très soluble dans les solvants organiques usuels tels que les alcools, les cétones, les esters ou les éthers.N, N-diethyl ethyl-2 hexanamide is a colorless liquid, boiling at 87 ° C under a pressure of 1.5 mm of mercury, very soluble in the usual organic solvents such as alcohols, ketones, esters or ethers.

La teneur des compositions selon l'invention en N,N-diéthyl éthyl-2 hexanamide exprimée en pourcentage en poids dans la composition considérée dépend de la nature de ladite composition (base pour parfum ou eau de toilette par exemple) et de la puissance et de la nature de l'effet recherché au niveau du produit final. Il va de soi que dans une base pour parfum la teneur en N,N-diéthyl éthyl-2 hexanamide peut être très importante, par exemple supérieure à 50 % en poids et peut atteindre 90 % en poids tandis que dans ûn parfum, une eau de toilette, une lotion après rasage ou un savon, cette teneur pourra être très inférieure à 50 % en poids. Ainsi la limite inférieure de la teneur en N,N-diéthyl éthyl-2 hexanamide peut être celle qui provoque une modification perceptible à l'odorat de la fragrance ou de la note du produit fini. Dans certains cas, cette teneur minimale peut être de l'ordre de 0,01 % en poids. On peut évidemment faire appel à des teneurs non comprises dans les limites des teneurs indiquées ci-avant sans pour autant sortir du cadre de la présente invention.The content of the compositions according to the invention in N, N-2-ethyl-ethyl hexanamide expressed as a percentage by weight in the composition considered depends on the nature of said composition (base for perfume or eau de toilette for example) and on the power and the nature of the desired effect at the level of the final product. It goes without saying that in a perfume base the content of N, N-diethyl ethyl-2 hexanamide can be very high, for example greater than 50% by weight and can reach 90% by weight while in a perfume, a water toiletries, after shave lotion or soap, this content may be much less than 50% by weight. Thus the lower limit of the content of N, N-diethyl ethyl-2 hexanamide may be that which causes a perceptible change in the smell of the fragrance or of the note of the finished product. In certain cases, this minimum content can be of the order of 0.01% by weight. It is obviously possible to use contents which are not within the limits of the contents indicated above without departing from the scope of the present invention.

La N,N-diéthyl éthyl-2 hexanamide peut être préparée sans difficulté par réaction d'un halogénure d'éthyl-2 hexanoyle avec la diéthylamine en présence d'une base alcaline en solution aqueuse (soude ou potasse).N, N-diethyl 2-ethylhexanamide can be prepared without difficulty by reaction of a 2-ethylhexanoyl halide with diethylamine in the presence of an alkaline base in aqueous solution (soda or potash).

Les exemples suivants illustrent l'invention et montrent comment elle peut être mise en pratique.The following examples illustrate the invention and show how it can be practiced.
