Abstract

The invention relates to the use of ethyl 2-methylbenzoate as a perfume.

Description

Summary of the invention

[0001] The present invention relates to the use of ethyl 2-methylbenzoate 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 ethyl 2-methylbenzoate as the fragrance.

[0005] The ethyl 2-methylbenzoate used according to the invention may be present in any stereoisomeric form or in any mixture of stereoisomers.

[0006] What has been said here for ethyl 2-methylbenzoate, in particular the advantages stated here, also applies to the mixtures of the stereoisomers of ethyl 2-methylbenzoate used according to the invention.

[0007] Ethyl 2-methylbenzoate has very unique olfactory properties that are clearly different from and exceed known odorous substances. The suitability of ethyl 2-methylbenzoate 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] Ethyl 2-methylbenzoate has the following structural formula And, preferably, has the following characteristics: Cas number: 87-24-1

[0009] As mentioned above, its suitability as a fragrance is unknown. Likewise, there is no precise odor description, however, according to the inventors, ethyl 2-methylbenzoate smells pungent, medicinal, methyl salicylate-like, refreshing.

[0010] The inventors have therefore surprisingly found that ethyl 2-methylbenzoate is suitable as a fragrance and produces special effects in small doses in combination with other fragrances, in particular fragrances with aromatic and spicy notes.

[0011] In a preferred embodiment according to the present invention, ethyl 2-methylbenzoate is used in a perfume composition to obtain at least one of the following notes: strong, fresh, floral, natural, rich, fruity, refreshing, spicy, lasting, complex, delicate, green, less sweaty, less animal smell, less mushroom smell and / or less terpene smell. It is further preferred to use ethyl 2-methylbenzoate to impart, change and / or enhance aromatic and / or spicy spice notes. Preferably, ethyl 2-methylbenzoate is used to enhance aromatic and / or spicy spice notes. However, in view of the above-mentioned odor description, this is particularly surprising because ethyl 2-methylbenzoate itself does not impart any significant odor, and even enhances warm and / or spicy odor notes. In a preferred embodiment according to the present invention, ethyl 2-methylbenzoate enhances the aromatic and / or spicy notes of other spices.

[0012] The fact that the ethyl 2-methylbenzoate 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 (eg essential oils or fragrance mixtures), is particularly surprising.

[0013] Besides its main, olfactory properties, ethyl 2-methylbenzoate also has positive secondary properties, in particular high substantivity compared with fragrances with similar olfactory properties, high stability in certain media and formulations, high extensibility and is also biodegradable.

[0014] With regard to the preferred use of imparting, modifying and / or enhancing fragrance notes, it is also recognized that ethyl 2-methylbenzoate can function very well as a so-called enhancer (amplifier; intensifier). Preferably, ethyl 2-methylbenzoate is used as an enhancer of the warm, spicy and / or aromatic notes of other fragrances. In other words: ethyl 2-methylbenzoate can be used with other fragrances to enhance their warm, spicy and / or aromatic odor notes.

[0015] In addition, the ethyl 2-methylbenzoate used according to the present invention can enhance the intensity of the fragrance mixture (fragrance composition) and make the overall smell of the mixture round. Therefore, the compounds described herein can be used to give the fragrance composition greater intensity, freshness, floral fragrance, naturalness, richness, fruitiness, freshness, spicy taste, warmth, persistence, complexity, delicateness, greenness, less sweat, less animal smell, less fungus and / or less terpenes, in particular, the compounds can be used to give more fragrance, spiciness and / or warmth to the fragrance composition.

[0016] Furthermore, ethyl 2-methylbenzoate is suitable as an agent for increasing the substantivity and / or retention of a fragrance composition.

[0017] Ethyl 2-methylbenzoate can be used in a variety of products; it can be used as a single fragrance, but it can be particularly advantageously combined with other fragrances in different proportions to form fragrance mixtures, and can also produce new and original fragrance compositions. Therefore, one aspect of the present invention also relates to a fragrance mixture and possible other ingredients (solvents, etc.), which contains ethyl 2-methylbenzoate.

[0018] The fragrance composition according to the present invention comprises ethyl 2-methylbenzoate and at least one other fragrance or consists thereof. Preferably, the fragrance composition according to the present invention comprises ethyl 2-methylbenzoate and two or more other fragrances or consists thereof. More preferably, the fragrance composition according to the present invention comprises ethyl 2-methylbenzoate and three or more other fragrances or consists thereof. Most preferably, the fragrance composition according to the present invention comprises ethyl 2-methylbenzoate and four or more other fragrances or consists thereof.

[0019] The ethyl 2-methylbenzoate according to the invention is usually used in a sensory effective amount, ie in such total amount that it exerts a sensory effect.

[0020] Preferably, the weight ratio of ethyl 2-methylbenzoate to the total amount of other spices is in the range of 1:10 to 1:100, preferably 1:25 to 1:50.

[0021] In this context, preference is given to a total amount of ethyl 2-methylbenzoate in the range from 0.0001 to 99.9% by weight, preferably from 0.001 to 99.5% by weight, particularly preferably from 0.01 to 99% by weight, from 0.01 to 90% by weight, from 0.01 to 50% by weight, from 0.01 to 20% by weight and particularly preferably from 0.01 to 1.5% by weight, in particular from 0.01 to 1.0% by weight, in each case based on the total weight of the composition.

[0022] In a preferred embodiment according to the present invention, ethyl 2-methylbenzoate is included in the fragrance composition in an effective amount sufficient to modify the sensory notes of an existing fragrance to make it stronger, fresher, more floral, more natural, more intense, more fruity, more refreshing, more persistent, more complex, more delicate, greener, less sweaty, less animalic, less mushroomy and / or less terpeneic and / or to enhance the aromatic and / or spicy notes. Therefore, in a preferred embodiment according to the present invention, ethyl 2-methylbenzoate is preferably combined with at least one aromatic and / or spicy fragrance in the fragrance composition.
