Definitions
- the present invention relates to the field of perfumery. It concerns, in in particular, the use in perfumery of diethyl 1,4-cyclohexanedicarboxylate.
- the Diethyl 1,4-cyclohexanedicarboxylate indeed has a rare combination of fragrant flowery, fruity type, namely a flowery odor and whose character fruity evokes the smells of strawberry and pear, very ethereal, with a slight pineapple side background. It's a very natural fruit smell and not at all candied-lactonic, also endowed with remarkable tenacity for this type of odor.
- perfumery has a real lack of light fruity notes, ethereal and also tenacious.
- Fructone® (2-methyl-1,3-dioxolane-2-acetate ethyl; origin: International Flavors and Fragrances) has a certain tenacity.
- the only known fruity and tenacious notes at the same time are very food, evoking candied fruit and fruit compote more than the fruity note ethereal released by a fresh fruit. This is particularly the case for fruity lactones, ethyl methyl phenyl glycidate, raspberry ketone.
- the ethereal fruity notes known in the prior art are very volatile esters such as, for example, acetate hexyl, heptyl, octyl, allyl and ethyl caproate and ethyl butyrate. Unlike the latter, diethyl 1,4-cyclohexanedicarboxylate appears to be very stubborn, as well on wet as on textiles, as shown in the examples presented later.
- diethyl 1,4-cyclohexanedicarboxylate can be present in two stereoisomeric forms, which have odorous properties distinct from each other, and again from those of their mixtures.
- cis-1,4-cyclohexanedicarboxylate of diethyl has a more powerful and persistent odor than that of its trans configuration isomer, with a lot of volume, and in which the odorous characteristics typical of the mixture of isomers are best represented cited above.
- both the two isomers and their mixtures are useful fragrance ingredients.
- the cis configuration isomer and mixtures containing a quantity preponderant of this isomer are however preferred perfume ingredients according to the invention.
- Diethyl 1,4-cyclohexanedicarboxylate and its configuration isomers cis or trans can be used in fine perfumery as well as perfumery functional. They are suitable for the preparation of various perfume compositions, perfume bases and concentrates, as well as perfumes and eau de toilette, to which they impart very natural fruity characters. Their application in perfume various items such as soaps, shower or bath gels, shampoos, creams or lotions conditioner, cosmetic preparations or body or air fresheners is also advantageous.
- the proportions in which the compounds according to the invention can be incorporated in the aforementioned miscellaneous products vary in a range of values very extensive. These values are dependent on the nature of the product to be perfumed and the desired olfactory effect, as well as the nature of the co-ingredients in a composition given, when the compounds of the invention are used in admixture with perfuming co-ingredients, solvents or adjuvants customary in the art. Of course, the compounds according to the invention can also be added to the compositions and scented articles either alone or in solution in commonly used solvents.
- Diethyl 1,4-cyclohexanedicarboxylate and its isomers are either available on the market, either they can be easily prepared from products available on the market and using conventional reactions.
- diethyl 1,4-cyclohexanedicarboxylate can be prepared by simple esterification of this acid, using the appropriate alcohol and in the presence of an acid protonic or an acidic resin. This is a perfectly classic reaction, including the conditions are capable of being optimized by a person skilled in the art without others details are required here.
- this compound can be prepared from the corresponding dimethylated diester derived from benzene, which is commercially available (BASF or HÜLS), using conventional reactions illustrated in the following scheme:
- the reactions illustrated in this diagram are carried out under conditions conventional, described in detail below.
- the desired ester is obtained in the form of a mixture of cis and trans configuration isomers. Where appropriate, these isomers can then be separated from said mixture by crystallization from suitable solvents, in which only one of the isomers is soluble.
- a basic perfume composition was prepared by mixing the following ingredients: Ingredients Parts by weight Essence of synthetic amber 100 Bergamot essence 100 Iralia® 100 Musk ketone 80 50% absolute oak moss 250 Crystal foam 50 Essence of patchouli 70 Orange essence 40 Bourbon vetyver essence 80 Wardia® 80 Total 950
- composition A 50 parts by weight of diethyl 1,4-cyclohexanedicarboxylate were added to obtain a new composition A, 50 parts by weight of Fructone® to obtain composition B and 50 parts by weight of undecalactone to obtain a composition C.
- the latter then developed a chypre-like odor recalling the fragrance of the Liste® perfume by Rochas. It had a very powerful and dominant lactonic note, with a nutritional character.
- Composition B had a fruity, elegant odor but whose fruity character disappeared completely after 3 hours from the smell of a wet cloth soaked in this composition.
- the new composition A had an even more elegant odor than that of composition B and less fruity-food than that of composition C.
- its fruity, strawberry, pear character persisted throughout the day.
- a basic perfume composition was prepared using the following ingredients: Ingredients Parts by weight Benzyl acetate 75 Phenylethyl acetate 75 Bergamot essence 50 Citronellol 185 Geraniol 200 Linalol 60 Essence of patchouli 25 Phenethylol 260 Absolute rose 20 Bulgarian rose essence 10 Total 960
- composition A diethyl 1,4-cyclohexanedicarboxylate
- composition B Fructone®
- Perfumed detergent samples were prepared from an unscented detergent powder, to which were added 0.1% by weight of diethyl 1,4-cyclohexanedicarboxylate (sample A), Fructone® (sample B), respectively , hexyl acetate (sample C) and allyl caproate (sample D).
- samples of standard textiles were washed in four washing machines. The four batches of textiles were then evaluated blindly on leaving the machine and after drying, by a panel of expert perfumers, who had to judge the intensity of the fruity note exhaled over time, by assigning a value included in an increasing scale from 0 to 10.

- II. trans-1,4-cyclohexanedicarboxylate de diméthyle et cis-1,4-cyclohexane
dicarboxylate de diméthyleOn a filtré le 1,4-cyclohexanedicarboxylate de diméthyle (provenance: Hüls ;
rapport cis/trans 2:1; produit mi-solide/mi-liquide) pour séparer les eaux-mères
des cristaux. On a pris ces derniers (14,5 g) dans un mélange de 45 ml d'éther de
pétrole 30-50° et 7 ml de tert-butyl méthyl éther et cristallisé à chaud. Les cristaux
ainsi obtenus (9,2 g) contenaient le trans-1,4-cyclohexanedicarboxylate de
diméthyle (pureté : 98%) ayant les caractères analytiques suivants :

On a ainsi obtenu des cristaux (72,9g) qui ont été distillés sur colonne Vigreux de 15 cm (108°C/3x102Pa) pour fournir 37,08 g de cis-1,4-cyclohexanedicarboxylate de diméthyle (pureté : 96% ; mélange cis/trans 75:25) ayant les caractères analytiques suivants :
RMN(1H, 360MHz) : 3,68(s, 6H) ; 2,48(m, 2H) ; 1,90(m, 4H) ; 1,68(m, 4H) δppm

Alternativement, ils peuvent être préparés à partir des acides cis- et trans-1,4-cyclohexanedicarboxyliques, lesquels sont disponibles commercialement (Aldrich et Bader, par exemple) ou peuvent être facilement préparés à partir des dicarboxylates de diméthyle susmentionnés (saponification avec NaOH dans l'éthanol).

La composition B possédait une odeur fruitée, élégante mais dont le caractère fruité disparaissait complètement au bout de 3 h de l'odeur d'une mouillette trempée dans cette composition.
La composition nouvelle A possédait une odeur encore plus élégante que celle de la composition B et moins fruitée-alimentaire que celle de la composition C. Par ailleurs, son caractère fruité, fraise, poire a perduré pendant toute la journée. Ces effets étaient encore plus accentués lorsqu'on avait remplacé le 1,4-cyclohexanedicarboxylate de diéthyle par son isomère de configuration cis à l'état pur.

Avec ces quatre échantillons on a lavé, dans quatre machines à laver le linge, des lots de textiles standard. Les quatre lots de textiles ont ensuite été évalués à l'aveugle à la sortie de la machine et après leur séchage, par un panel d'experts parfumeurs, lesquels devaient juger l'intensité de la note fruitée exhalée dans le temps, en attribuant une valeur comprise dans une échelle croissante de 0 à 10.
Les résultats de cette évaluation à l'aveugle sont résumés dans le tableau suivant :
