Definitions

• the present invention relates to the use of a mixture of cis- and trans-3-methyl- ⁇ -decalactone, perfume compositions containing such a mixture and perfumed articles and a process for the preparation of a fragrance composition.
• fragrances in the perfume industry continues to have a general need for new fragrances that have beyond their primary, namely odor properties addition secondary positive secondary properties, such.
• B. a higher stability under certain conditions of use, a higher yielding or better adhesion, or by synergy with other fragrances lead to better sensory profiles.
• this primary object is achieved by the use of a mixture comprising cis- and trans-3-methyl- ⁇ -decalactone in a molar ratio in the range from 2: 3.5 to 3.5: 2, as a jasmone fragrance.
• cis- or trans-3-methyl- ⁇ -decalactone encompasses in each case the pure (cis or trans) enantiomers and also their enantiomer mixtures, in particular the racemic mixtures.
• the invention is based on the surprising finding that a mixture of cis- and trans-3-methyl- ⁇ -decalactone is suitable as a jasmone fragrance, although the individual substances are not jasmone fragrances.
• JP-A2 2000-086647 describes an enantioselective synthesis for both enantiomers of cis-3-methyl- ⁇ -decalactone. It describes the use in perfume oils and flavors.
• JP-A2 09-169624 relates to the use of C 11 -C 16 - ⁇ -lactones as antimicrobial agents in toothpaste or mouthwash.
• the main focus of the synthesizing perfume chemist and composing perfumer is usually to preferentially isolate, analyze, make and use, for compounds with different stereoisomers, that which has the strongest impact or which is most typical of the odor of a structure.
• the perfumers also classified the strength of the two pure isomers on a scale of 1-6 (see below).
• the perfumers evaluated neither the pure cis isomer with its coconut aspects nor the pure trans isomer with its fruity peach aspects as the sensory most valuable product, but according to the above table, the mixtures of both isomers with a molar cis / trans Ratio of 60:40 or 40:60 (ie 3: 2 or 2: 3). This applies both in terms of olfactory evaluation, as well as for application criteria such as the adhesion to smelling strips and the charisma.
• the optimum mixing ratio of the isomers is approximately at a cis content of 36.4-63.6% and a corresponding trans proportion of 63.6-36.4%.
• Another aspect of the present invention relates to the use of cis-3-methyl- ⁇ -decalactone in a fragrance composition containing trans-3-methyl- ⁇ -decalactone to enhance the trans-3-methyl- ⁇ -decalactone mediated peach odor , Interestingly, by adding cis-3-methyl- ⁇ -decalactone, the peach odor of the trans-3-methyl- ⁇ -decalactone can be enhanced, although the cis compound itself has no such peach odor;
• the cis connection acts as an enhancer. It follows from the above that at the same time a jasmonic olfactory aspect is added, which is to be determined neither in the pure cis nor in the pure trans connection.
• the invention also relates to a method for imparting, enhancing or modifying a jasmonic odor in a fragrance composition, the fragrance composition comprising an amount of a mixture of cis- and trans-3-methyl- ⁇ -decalactone in a molar ratio in the range of 2: 3, 5 to 3.5: 2 sufficient to impart, enhance or modify a jasmonic odor.

• Starting from a fragrance composition, which already has a jasmonigen smell can by adding the mixture of cis- and trans-3-methyl- ⁇ -decalactone, an enhancement or modification of the jasmone odor can be effected.
• a fragrance composition having a strong peach odor is prepared by adding a compound (trans-3-methyl- ⁇ -decalactone) which itself only is able to mediate a weak peach odor and in addition a compound (cis-3-methyl- ⁇ -decalactone) is added as an enhancer which is suitable for the trans-3-methyl- ⁇ -decalactone-mediated peach Reinforce smell.
• the invention also relates to a method for enhancing a trans-3-methyl- ⁇ -decalactone-mediated peach odor in a fragrance composition, wherein the fragrance composition is added an effective amount of cis-3-methyl- ⁇ -decalactone.
