Abstract

To provide compounds that allow for the active modification of known scents and / or improve the fragrance profile even in small amounts, thus increasing the palette of scents offered to consumers. The present invention proposes the use of small amounts of linolal as an enhancer and / or regulator in fragrance compositions in order to positively influence fruity and spicy notes.

Description

[Technical field]

[0001] The present invention relates to the use of linolal as a fragrance enhancer, modifier and / or imparter.Furthermore, the present invention relates to fragrance compositions, their uses and methods for imparting, modifying and / or enhancing specific fragrance notes. [Background technology]

[0002] In the perfume industry, there is a constant need to develop new fragrances to expand the olfactory palette and satisfy consumer demands. However, the creation of new fragrances or fragrance compositions entails many challenges. For example, it is necessary to select a small number of specific compositions of fragrances from an almost unlimited number of possible structures known from the prior art in order to prepare a product that meets the specific needs of the market and matches the profile required by the customer. It is possible.

[0003] Combining multiple known fragrances can create a scent that consumers perceive as novel and exciting. This process requires combining multiple compounds for one product. However, the cost of the basic ingredients of fragrances and fragrance compositions is high, and as a result, the perfume industry is interested in utilizing fragrances as efficiently as possible. Adding more compounds to already known fragrances to create new scents is an effective way to enhance the scent palette. Compounds that enhance or modify new or known fragrances or compositions are in high demand because the resulting products can have superior properties in terms of the overall perception of the scent. However, it is difficult to identify compounds or compositions that modify and / or enhance the scent profile of known fragrances or fragrance compositions to create new scents. Currently, it is not possible to match compounds based on chemical structure alone to create a pleasant scent. Therefore, rigorous testing of fragrance combinations and concentrations by industry experts is required to identify new candidates. In particular, the identification of additional compounds that can modify known fragrances by providing trace amounts of the additional compounds is highly desirable, since the addition of the compounds may create a large number of new scents from known fragrances or fragrance compositions. This method is cost-effective, since only small amounts are required to enhance and / or modify already known scents. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication 2008-19441 Summary of the Invention [Means for solving the problem]

[0005] Thus, the objective underlying the present invention is to provide compounds which allow the active modification of known scents and / or enhance the fragrance profile even in small amounts, thus increasing the palette of scents offered to the consumer. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0006] This is solved by using linolal in combination with at least one other fragrance to impart, modify and / or enhance the odor profile of the fragrance composition.

[0007] Linolal is a mixture of C13 and C15 aldehydes.

[0008] In a preferred embodiment, the C13 and C15 aldehydes are present in a weight ratio of about 1:100 to about 100:1.

[0009] In a preferred embodiment, linolal is a mixture of compounds according to CAS number 93821-14-8.

[0010] In a preferred embodiment, linolal is the hydroformylation product of C12 to C14 alkenes.

[0011] In a preferred embodiment, the linolal is a reaction mass of pentadecanal, tridecanal, 2-methyldodecanal and 2-methyltetradecanal.

[0012] Linolal is known in the fragrance industry and its fragrance profile is described as consisting of aldehydes, fatty, coniferous and floral notes.

[0013] Surprisingly, it has been found that the addition of a small amount of linolal to a fragrance composition significantly changes the odor profile of the composition in a positive way. In particular, the spicy and / or fruity notes of the fragrance composition are affected by the addition of linolal. The addition of a small amount of linolal has been shown to modify the fruity notes already present in the fragrance composition, imparting in particular the sensation of notes associated with watermelon, raspberry, banana, pear, apricot, peach, mandarin peel, and citrus. Similarly, spicy notes are also positively influenced by the addition of linolal, imparting in particular the sensation of almond, coriander, basil, bergamot peel, eucalyptus, pepper, cinnamon, cassia, bay oil, caraway, anise, and cardamom. However, these results are particularly surprising, since linolal does not have a fruity or spicy odor by itself, and has not been described to affect the odor characteristics of fragrance compositions that promote such odors.

[0014] In connection with the preferred use for imparting, modifying and / or enhancing fragrance notes, it is recognized that linolal performs an excellent function as a so-called booster.

[0015] Even more surprisingly, small amounts of linolal were able to enhance already present spicy and / or fruity notes of the fragrance composition.

[0016] In the context of the preferred uses according to the invention, linolal is used in an effective sensory amount, which is the total amount (=active amount) required to provide a sensory effect, either alone or in combination with further compounds or compositions.

[0017] In a preferred embodiment, linolal is used with at least one fragrance and / or composition to create a fragrance composition. Said fragrance composition can be obtained by methods known in the art, such as simple mixing or homogenization of the ingredients. The at least one other fragrance and / or composition can be any other fragrance or composition.

[0018] Thus, the present invention relates to the use of linolal and at least one further compound and / or composition as a fragrance composition, wherein the linolal is contained in an organoleptically effective amount sufficient to impart, modify and / or enhance the fruity and / or spicy notes of an existing fragrance.

[0019] In a preferred embodiment of the present invention, the fruity notes are selected from the group consisting of watermelon, raspberry, banana, pear, apricot, peach, mandarin peel, and citrus.

[0020] In a preferred embodiment of the present invention, the spicy notes are selected from the group consisting of almond, coriander, basil, bergamot peel, eucalyptus, pepper, cinnamon, cassia, bay oil, caraway, anise, and cardamom.

[0021] Linolal can be used in a variety of products and can be particularly advantageously combined with other fragrances in different ratios to form fragrance mixtures, which can lead to the creation of new and unique perfume compositions. Thus, one aspect of the present invention relates to fragrance mixtures that include linolal and, optionally, further components, such as solvents.

[0022] In preferred embodiments of the present invention, the amount of linolal ranges from 0.00001 to 99.9% by weight, more preferably from 0.001 to 5% by weight, and most preferably from 0.05 to 1% by weight, based on the total weight of the fragrance composition.

[0023] In a preferred embodiment of the invention, the weight ratio of linolal to the total amount of other fragrances ranges from 1:100,000 to 1:20, more preferably from 1:20,000 to 1:1,000.

[0024] Examples of fragrances which may be advantageously combined with linolal in the context of the present invention can be found, for example, in S. Arctander, Perfume and Flavor Materials, Vol. I and II, Montclair, NJ 1969, self-published, or K. Bauer ei a / ., Common Fragrance and Flavor Materials, 4th Edition, Wiley-VCH, Weinheim 2001.

[0042] In the following, the invention will be further characterized on the basis of examples. EXAMPLES

[0043] Examples 1-13: <Effect of trace amounts of linol on fragrance compositions>

[0044] To investigate the effect of linolal in enhancing or modifying the odor profile, known fragrance compounds or compositions were mixed with a working amount of linolal. The resulting odor changes are reported in Table 1, as compared to compositions without linolal. The amount of linolal is given as a weight percent of the total composition.

[0045] Table 1: The addition of trace amounts of linoleic acid enhances and modifies the fragrance profile. [Table 1]

[0046] These data indicate that linolal has a strong impact on fragrance compositions to modify and enhance already present notes.

[0047] Example 14: <Fragrance composition containing a small amount of linol> Table 2: Fragrance mixtures [Table 2]

[0048] According to the expert panel, the linoleum ingredient gives this fruity scent even more juiciness and enhances the natural peach notes with its sparkling effect, enhancing the overall fragrance and revealing a more spectacular fruity profile. Example 15: <Fragrance composition containing a small amount of linol>

[0049] Table 3: Fragrance mixtures [Table 3]

[0050] According to the expert panel, the metallic notes of Linolal give the sparkling cinnamon note a boost, making it more impactful. Overall, it enhances all the spiciness of the fragrance and can be used as a trail to power the spicy top notes.

[0051] The examples presented clearly show the impact of trace amounts of linolal in modifying and enhancing particularly spicy and fruity notes in fragrance compositions.
