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 linalool as a fragrance enhancer, modifier and / or imparting agent. Furthermore, the present invention relates to fragrance compositions, their use, and methods for imparting, modifying and / or enhancing specific fragrance notes.

Background Art

[0002] In the perfume industry, there is always a need to develop new fragrances in order to enhance the fragrance palette and meet consumer demands. However, creating new fragrances or fragrance compositions involves many challenges. For example, in order to meet specific market needs and provide products that match the profiles required by customers, it is necessary to select specific compositions of a small number of fragrances from a nearly unlimited number of possible structures known from the prior art. can be done.

[0003] By combining multiple known fragrances, it is possible to create scents that consumers find novel and stimulating. In this process, it is necessary to combine multiple compounds for one product. However, the cost of the basic components of fragrances and fragrance compositions is high, and as a result, the perfume industry is interested in using fragrances as efficiently as possible. Adding further compounds to already known fragrances to create new scents is an effective way to enhance the fragrance palette. Compounds that enhance or modify new or known fragrances or compositions are in high demand because the resulting products can have excellent properties with respect to 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 in order to create new scents. Currently, it is impossible to match compounds based solely on their chemical structure to create a pleasant fragrance. Therefore, rigorous testing of fragrance combinations and concentrations by industry experts is necessary to identify new candidates. In particular, the identification of additional compounds that can modify known fragrances by supplying trace amounts is highly desirable, as the addition of these compounds has the potential to create numerous novel scents from known fragrances or fragrance compositions. This method is cost-effective because only small amounts are needed to enhance and / or modify already known scents. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2008-19441 [Overview of the Initiative] [Means for solving the problem]

[0005] Thus, the underlying objective of this intent is to provide compounds that enable the active modification of known scents and / or enhance fragrance profiles, even in small amounts, thereby increasing the palette of scents offered to consumers. [Modes for carrying out the invention]

[0006] This is resolved by using linoral in combination with at least one other fragrance to impart, modify, and / or enhance the fragrance 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, linoral is a mixture of compounds according to CAS number 93821-14-8.

[0010] In a preferred embodiment, linoral is a hydroformylation product of a C12 to C14 alkene.

[0011] In preferred embodiments, linol is the reaction mass of pentadecanal, tridecanal, 2-methyldodecanal, and 2-methyltetradecanal.

[0012] Linoral is well-known in the fragrance industry, and its fragrance profile is described as consisting of notes related to aldehydes, fats, conifers, and flowers.

[0013] Surprisingly, it was found that adding small amounts of linoral to fragrance compositions significantly altered the fragrance profile of those compositions in a positive way. In particular, the spicy and / or fruity notes of the fragrance compositions were affected by the addition of linoral. The addition of small amounts of linoral modified the fruity notes already present in the fragrance compositions, imparting sensations of notes such as watermelon, raspberry, banana, pear, apricot, peach, mandarin peel, and citrus. Similarly, spicy scents were also positively affected by the addition of linoral, imparting sensations of notes such as almond, coriander, basil, bergamot peel, eucalyptus, pepper, cinnamon, cassia, bay oil, caraway, anise, and cardamom. However, these results are particularly surprising because linoral itself does not possess a fruity or spicy scent, and it has not been reported that it affects the fragrance characteristics of fragrance compositions that promote such scents.

[0014] In relation to its preferred use for imparting, modifying, and / or enhancing fragrance notes, linoral is recognized as functioning well as a so-called booster (amplifier; enhancer).

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

[0016] In connection with the preferred use according to the present invention, linoral is used in a functionally effective amount. A functionally effective amount is the total amount (= effective amount) required to impart a functional effect, either alone or in combination with further compounds or compositions.

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

[0018] Accordingly, the present invention relates to the use of linoral and at least one further compound and / or composition as a fragrance composition, wherein the linoral is contained in a sensory 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 note is 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 note is selected from the group consisting of almond, coriander, basil, bergamot peel, eucalyptus, pepper, cinnamon, cassia, bay oil, caraway, anise, and cardamom.

[0021] Linalool can be used in various products, and in particular, it can be advantageously combined with other fragrances in different proportions to form a fragrance mixture, and can also create new and original perfume compositions. Therefore, one aspect of the present invention relates to a fragrance mixture containing linalool and optionally further components (such as solvents).

[0022] In a preferred embodiment of the present invention, the amount of linalool 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 present invention, the weight ratio of linalool to the total amount of other fragrances ranges from 1:100000 to 1:20, more preferably from 1:20000 to 1:1000.

[0024] Examples of fragrances that can be advantageously combined with linalool in the context of the present invention can be found, for example, in S. Arctander, Perfume and Flavor Materials, Vol. I and II, Montclair, N. J. 1969, self-published, or K. Bauer et al., Common Fragrance and Flavor Materials, 4th Edition, Wiley-VCH, Weinheim 2001.

[0042] The present invention will be further characterized below based on examples. [Examples]

[0043] Examples 1-13: <The effect of trace amounts of linoleic acid on fragrance compositions>

[0044] To investigate the effect of linoral on enhancing or modifying fragrance profiles, known fragrance compounds or compositions were mixed with practical amounts of linoral. The resulting fragrance changes are reported in Table 1, compared to compositions without linoral. The amount of linoral is expressed as a weight percentage of the total composition.

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

[0046] These data indicate that linoral has a strong influence on fragrance compositions, modifying and enhancing existing notes.

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

[0048] According to the expert panel, linoral ingredients add juiciness to this fruity scent and enhance the natural peach aroma with their sparkling effect. The overall fragrance is strengthened, resulting in a more wonderful fruity profile. Example 15: <Fragrance composition containing a small amount of linoleum>

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

[0050] According to the expert panel, the metallic notes of linoral enhance the sparkling cinnamon notes, giving them more impact. Overall, it can be used to elevate all the spiciness in the fragrance and as a supporting element that empowers the spicy top notes.

[0051] The presented examples clearly demonstrate the effect of trace amounts of linoleic acid in modifying and enhancing particularly spicy and fruity notes in fragrance compositions.
