Definitions

• the present invention relates to the field of perfumery. It relates more particularly to the use as perfuming ingredient of at least one pentadecenolide of formula having a trans configuration double bond in one of positions 11 or 12 as indicated by the dotted lines.
• the above-mentioned compounds are unsaturated macrocyclic lactones whose chemical structure is known. They have, in fact, been cited as secondary or intermediate products of a process for the preparation of odoriferous saturated macrolides such as pentadecanolide, known under the trade name of EXALTOLIDE® (origin: Geneva, Switzerland), and the like [see, for example, French Patent FR-A-2,043,784 or J. Becker and G. Ohloff, Helv. Chim. Acta 54 , 2889 (1971)].
• an appropriate peroxide was split by means of thermal energy or radiation, or else chemical agents, to obtain a mixture containing the desired saturated lactones, as well as the corresponding unsaturated lactones.
• the saturated lactones were then either separated from this mixture by the usual separation techniques, or obtained by hydrogenation of said mixture or of the unsaturated lactones contained.
• the unsaturated lactones and in particular those of trans configuration mentioned above, namely the trans-pentadec-12-en-15-olide and trans-pentadec-11-en-15-olide, have properties very interesting odorants and that they can therefore be used advantageously for the preparation of perfume compositions and perfumed products.
• these lactones and their mixtures are used to develop fragrant notes of musk, animal type, very powerful and very effective for notes of this type, the smell of trans-pentadec-11-en-15-olide being however less potent than that of trans-pentadec-12-en-15-olide.
• the latter also has a more marked musk-ambrette and fruity-pear connotation and is preferred according to the invention.
• pentadecanolide Compared to their saturated analogue, namely pentadecanolide or EXALTOLIDE®, the aforementioned pentadecenolides, as well as their mixtures, have clearly more animal-like fragrant notes, with a connotation reminiscent of natural musk. In addition, they have the advantage of having fragrant notes whose power, volume and tenacity are much higher than those of the fragrant note characterizing pentadecanolide.
• the compounds of formula (I) have odorous notes which are distinct from those of their isomers represented by the formula having a double bond of cis configuration in one of the positions 11 or 12 as indicated by the dotted lines.
• the latter present, in fact, musky-type olfactory notes, less animal and elegant, as well as less powerful, than those of the corresponding trans-pentadecenolides (I).
• the abovementioned unsaturated macrocyclic lactones can be used in perfumery in very varied applications. They lend themselves as well to the preparation of perfumes and colognes, as to the scenting of functional products such as soaps, shower or bath gels, shampoos, body or room air fresheners, cosmetic products and cleaning products. Due to the substantiality of their rating, they prove to be particularly advantageous for the perfuming of detergents or textile conditioners.
• these unsaturated lactones can be used in the pure state or in a mixture with one or more perfuming ingredients, solvents or usual supports.
• these pentadecenolides combine very harmoniously with one another, or else with the corresponding saturated lactone already mentioned, namely pentadecanolide.
• the mixtures of trans-pentadec-11-en-15-olide and trans-pentadec-12-en-15-olide may contain relative proportions of these two lactones varying over a very wide range of values.
• trans-pentadec-11-en-15-olide and trans-pentadec-12-en-15-olide, or their mixtures, can be used for the perfume applications according to the invention.
• concentrations of the order of 1 to 10%, or even 20% by weight, relative to the weight of composition in which these lactones are incorporated can be used. These concentrations may be lower than the values quoted when perfuming articles such as soaps and shower or bath gels, shampoos, cosmetic products or detergents or textile conditioners.
• the aforementioned unsaturated macrocyclic lactones can be prepared from 2- (3-hydroxypropyl) -1-cyclododecanone (the preparation of which is described in patent FR-A-2 043 784 cited above) according to a process analogous to that described by SL Schreiber and aI. in J. Am. Chem. Soc. 102 , 6163 (1980) and 107 , 2980 (1985) for the preparation of macrolides.
• the specific conditions for the preparation of these lactones were as follows.
• trans-pentadec-11-en-15-olide trans-pentadec-12-en-15-olide, as well as their mixtures according to the invention, are designated under the generic name of (E, Z ) -pentadéc-11 (12) -én-15-olide.
• a basic musk-type perfume composition was prepared for a masculine cologne by mixing the following ingredients:
• composition A 400 parts by weight of (E, Z) -pentadec-11 (12) -en-15-olide were added on the one hand to prepare a new composition A and, on the other hand, 400 parts by weight of EXALTOLIDE® to prepare a composition B.
• Compositions A and B were evaluated by a panel of expert perfumers. In the unanimous opinion of the latter, composition A had a much more musky, animal and powerful fragrant note than that of composition B.
