Abstract
Description
Summary of the invention
[0001] The present invention relates to the use of 1-(methoxymethyl)-2-methylbenzene as a fragrance. In addition, the present invention relates to fragrance compositions, their use and methods for imparting, modifying and / or enhancing certain fragrance notes. Background Art
[0002] As far as the perfume industry is concerned, there is a permanent need for new perfume creations. However, the creation of new fragrances or fragrance compositions involves many challenges. For example, it is necessary to select a specific composition of several fragrances from an almost infinite number of possible structures known from the prior art in order to meet specific needs of the market and to provide a product that matches the specific characteristics desired by the customer. Suitable fragrances exhibit very beneficial properties, but in combination with other fragrances may produce unpleasant and therefore harmful odors, making them difficult or even impossible to use for a specific purpose.
[0003] A second important problem relates to the need to provide fragrance compositions which are not only consistent with a specific odor profile but also have so-called secondary beneficial properties. In fact, many fragrance compositions known on the market have significant disadvantages in use, such as poor solubility and storage stability, but also have deficiencies in subjective issues such as richness, charm, etc. In addition, many known fragrance compositions require high dosages to achieve the desired odor result. Another requirement currently placed on fragrances is high biodegradability as well as dermatological and toxicological safety. Therefore, there is a particularly high need to provide fragrances which, even in small doses, have a large impact on other fragrances and transform rather unpleasant odor impressions into positive odor impressions and / or enhance pleasant odor impressions.
[0004] The problem underlying the present invention is therefore to provide a new fragrance which is able to enhance the positive and beneficial odor aspects of other fragrances and / or (at the same time) reduce, inhibit and / or mask the undesirable unpleasant odor aspects. In particular, the new fragrance should also have the characteristics of improving the stability, solubility and overall performance of other fragrances, as well as reducing the required dosage. Finally, the fragrance composition itself should have excellent biodegradability and be harmless to humans and the environment. Summary of the invention
[0004] This was solved by using 1-(methoxymethyl)-2-methyl-benzene as the fragrance.
[0005] The 1-(methoxymethyl)-2-methylbenzene used according to the invention may be present in any stereoisomeric form or in any mixture of stereoisomers.
[0006] What is stated herein for 1-(methoxymethyl)-2-methyl-benzene, in particular the advantages stated herein, also applies to the mixtures of stereoisomers of 1-(methoxymethyl)-2-methyl-benzene used according to the invention.
[0007] 1-(Methoxymethyl)-2-methyl-benzene has very unique olfactory properties that are clearly different from and exceed known odorous substances. The suitability of 1-(Methoxymethyl)-2-methyl-benzene as a fragrance was previously unknown. It is therefore particularly surprising that a valuable, interesting fragrance with complex olfactory properties could be found in an already well-studied field.
[0008] 1-(Methoxymethyl)-2-methyl-benzene has the following structural formula And, preferably, it has the following characteristics: Cas number: 15018-12-9
[0009] As mentioned above, its suitability as a fragrance is unknown. Likewise, there is no precise odor description, however, according to the inventors, 1-(methoxymethyl)-2-methyl-benzene smells phenolic, cresolic, bromostyrene-like, leathery, indole-like.
[0010] The inventors have therefore surprisingly found that 1-(methoxymethyl)-2-methyl-benzene is suitable as a fragrance and produces a special effect in small doses in combination with pleasant-smelling compounds, wherein these compounds are different from 1-(methoxymethyl)-2-methyl-benzene.
[0011] In a preferred embodiment according to the invention, 1-(methoxymethyl)-2-methyl-benzene is used to enhance one or more pleasant olfactory impressions of one or more pleasant smelling compounds, wherein the compound / these compounds are different from 1-(methoxymethyl)-2-methyl-benzene. Preferably, the one or more pleasant olfactory impressions of one or more pleasant smelling compounds are selected from the enhancement and / or improvement of creaminess, naturalness, softness and / or the enhancement or improvement of floral odor notes. This means that 1-(methoxymethyl)-2-methyl-benzene preferably enhances or improves the creaminess, naturalness, softness and / or floral odor notes of pleasant smelling compounds. However, in view of the above-mentioned odor description, this is particularly surprising because 1-(methoxymethyl)-2-methyl-benzene itself does not impart any significant pleasant odor, or even enhances one or more pleasant olfactory impressions of one or more pleasant smelling compounds.
[0012] As used herein, the singular forms "a", "an", and "the" include plural references unless the context clearly dictates otherwise. For example, the term "a compound" or "at least one compound" may include a plurality of compounds, including mixtures thereof. Furthermore, unless the context clearly dictates otherwise, plural forms include singular embodiments. For example, the term "one or more pleasant smelling compounds" also includes embodiments having only one pleasant smelling compound.
[0013] The fact that the 1-(methoxymethyl)-2-methyl-benzene used according to the invention can impart a very complex and varied overall sensory impression, which is usually only achievable with mixtures of several components, such as essential oils or fragrance mixtures, is particularly surprising.
[0014] In addition to its main, i.e. olfactory, properties, 1-(methoxymethyl)-2-methyl-benzene also has positive secondary properties, in particular a high substantivity compared to fragrances with similar olfactory properties, as well as a high stability in certain media and formulations, a high extensibility and it is also biodegradable.
[0015] It is also known that 1-(methoxymethyl)-2-methyl-benzene can function very well as a so-called enhancer (amplifier; intensifier). Preferably, 1-(methoxymethyl)-2-methyl-benzene is used as an enhancer of one or more pleasant olfactory impressions of one or more pleasant odorous compounds. In other words: the use of 1-(methoxymethyl)-2-methyl-benzene together with other pleasant odorous compounds enhances their pleasant odor notes.
[0016] In addition, the 1-(methoxymethyl)-2-methyl-benzene used according to the present invention can enhance the intensity of the fragrance composition and make the overall smell of the mixture mellow. Therefore, the compounds described herein can be used to impart more creaminess, naturalness, softness and / or enhanced floral olfactory notes to other compounds, especially pleasant smelling compounds with at least one or more pleasant olfactory impressions. In addition, 1-(methoxymethyl)-2-methyl-benzene is suitable as an agent for increasing the affinity and / or retention of fragrance compositions.
[0017] In the context of the present invention, "pleasant odor compounds" are generally understood to be substances which cause one or more pleasant odor impressions, whether as primary or as secondary / subordinate olfactory notes. The terms "pleasant odor compounds" and "fragrances" are used interchangeably in the context of the present invention.
[0018] Preferably, the one, more or all pleasant-smelling compounds different from 1-(methoxymethyl)-2-methyl-benzene are selected from the group consisting of fragrances having a molar mass in the range of 150 g / mol to 285 g / mol, in particular alcohols, aldehydes, ketones, ethers, esters and carboxylates having a molar mass in the range of 150 g / mol to 285 g / mol.
[0019] In a preferred embodiment according to the present invention, the ratio of the total mass of pleasant-smelling compounds to the total mass of 1-(methoxymethyl)-2-methyl-benzene is in the range of 0.1:99.9 to 1:99.
[0020] 1-(Methoxymethyl)-2-methyl-benzene can be used in a variety of products; it can be used as a single fragrance, but also particularly advantageously combined with other pleasant smelling compounds, in particular fragrances in different proportions to form fragrance mixtures, and also to produce new and original fragrance compositions. Preferably, the amount of 1-(methoxymethyl)-2-methyl-benzene is insufficient to produce an intrinsic odor, in particular a phenolic or cresol odor. 1-(Methoxymethyl)-2-methyl-benzene has the advantage that when used according to the invention, it is effective at such low concentrations that it does not produce, or at least does not produce a perceptible, intrinsic odor of its own. This allows the production of particularly advantageous fragrance compositions or products with any fragrance orientation.
[0021] Therefore, one aspect of the present invention also relates to a fragrance mixture and possibly other ingredients (solvents etc.) containing 1-(methoxymethyl)-2-methyl-benzene.
[0022] The fragrance composition according to the present invention comprises or consists of 1-(methoxymethyl)-2-methyl-benzene and at least one other pleasant smelling compound different from 1-(methoxymethyl)-2-methyl-benzene. Preferably, the fragrance composition according to the present invention comprises or consists of 1-(methoxymethyl)-2-methyl-benzene and two or more other pleasant smelling compounds different from 1-(methoxymethyl)-2-methyl-benzene. More preferably, the fragrance composition according to the present invention comprises or consists of 1-(methoxymethyl)-2-methyl-benzene and three or more other pleasant smelling compounds different from 1-(methoxymethyl)-2-methyl-benzene. Most preferably, the fragrance composition according to the present invention comprises or consists of 1-(methoxymethyl)-2-methyl-benzene and four or more other pleasant smelling compounds different from 1-(methoxymethyl)-2-methylbenzene.
[0023] 1-(Methoxymethyl)-2-methyl-benzene according to the invention is usually used in an organoleptically effective amount, ie in such total amount that it exerts its organoleptic effect.
[0024] Preferably, the weight ratio of 1-(methoxymethyl)-2-methylbenzene to the total amount of pleasant-smelling compounds other than 1-(methoxymethyl)-2-methyl-benzene is in the range of 1:5 to 1:100.
[0025] According to a preferred embodiment of the present invention, 1-(methoxymethyl)-2-methyl-benzene is contained in the fragrance composition in a sensory effective amount sufficient to enhance one or more pleasant olfactory impressions of one or more pleasant-smelling compounds different from 1-(methoxymethyl)-2-methyl-benzene, in particular for enhancing or improving the creaminess, naturalness, softness and / or floral olfactory notes of one or more pleasant-smelling compounds.
