Ethyl 2-methylbenzoate as a fragrance

Abstract

The present invention proposes the use of ethyl 2-methylbenzoate as a fragrance.

Description

[Technical field]

[0001] The present invention relates to the use of ethyl 2-methylbenzoate as a fragrance. 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, new fragrance creations are constantly sought. However, the creation of new fragrances and fragrance compositions entails many challenges. For example, in order to satisfy a specific need of the market and to offer a product that matches the specific profile required by the customer, it is necessary to select a small number of specific compositions of fragrances from the almost infinite number of possible structures known from the prior art. The right fragrance may show very beneficial performances, but when combined with other fragrances, it may develop unpleasant and therefore unfavourable odour aspects, making it difficult or even impossible to use for certain purposes.

[0003] A second important challenge concerns the need to provide a fragrance composition that not only meets a specific odor profile, but also has so-called secondary beneficial properties. Indeed, many fragrance compositions known on the market not only have significant drawbacks in use, such as poor solubility and poor stability on storage, but also fail in subjective tasks, such as richness, charisma, etc. Furthermore, many of the known fragrance compositions require high dosages to obtain the desired odor result. Another demand for today's fragrances is high biodegradability and dermatological and toxicological safety. Therefore, there is a particular demand to provide fragrances that, even in small amounts, have a significant effect on other fragrances, changing a rather unpleasant odor impression into a positive one and / or enhancing a pleasant odor impression. Summary of the Invention [Problem to be solved by the invention]

[0004] The problem underlying the present invention was therefore to provide novel fragrances capable of enhancing the positive and beneficial fragrance aspects of other fragrances, and / or (at the same time) reducing, suppressing and / or masking the undesirable and unpleasant fragrance aspects.In particular, said novel fragrances should also be characterized by improving the stability, solubility and overall performance of other fragrances, and reducing the dosage required.Finally, said fragrance composition itself should have excellent biodegradability and be harmless to humans and the environment. [Means for solving the problem]

[0005] This problem is solved by using ethyl 2-methylbenzoate as the flavoring agent.

[0006] The ethyl 2-methylbenzoate used according to the invention may exist in any stereoisomeric form or as a mixture of any stereoisomers.

[0007] All that has been said herein for ethyl 2-methylbenzoate, and in particular the advantages described herein, also apply to mixtures of stereoisomers of ethyl 2-methylbenzoate used or employed in accordance with the present invention.

[0008] Ethyl 2-methylbenzoate has olfactory properties that are highly unique and clearly different from and superior to those of known odorants. The suitability of ethyl 2-methylbenzoate as a fragrance agent was previously unknown. It is therefore particularly surprising to discover a fragrance agent with valuable, interesting and complex olfactory properties in an already well-studied field.

[0009] Ethyl 2-methylbenzoate has the following structural formula: [ka] and preferably has the following characteristics: Cas number: 87-24-1.

[0010] As mentioned above, its suitability as a fragrance is unclear. Similarly, no exact odor description is available, but according to the inventors, ethyl 2-methylbenzoate has a strong, medicinal, fresh odor, second only to methyl salicylate.

[0011] As a result, the inventors have made the surprising discovery that ethyl 2-methylbenzoate is suitable as a fragrance and that, in small amounts, it can provide special effects in combination with other fragrances, particularly fragrances having aromatic and spicy notes.

[0012] In a preferred embodiment according to the present invention, ethyl 2-methylbenzoate is used in the perfume composition to obtain at least one of the following perfume notes: strong note, clean note, floral note, natural note, voluminous note, fruity note, fresh note, spicy note, persistent note, complex note, fine note, green note, low sweaty note, low animal note, low mushroom note and / or low terpene note. Further preferred is the use of ethyl 2-methylbenzoate to impart, modify and / or enhance aromatic perfume notes and / or spicy perfume notes. Preferably, ethyl 2-methylbenzoate is used to enhance aromatic perfume notes and / or spicy perfume notes. However, this is particularly surprising in light of the above odor description, since ethyl 2-methylbenzoate does not impart a significant odor of its own, and even enhances warm odor notes and / or spicy odor notes. In a preferred embodiment according to the invention, ethyl 2-methylbenzoate enhances the aromatic and / or spicy notes of other perfumes.

[0013] Particularly surprising is the fact that the ethyl 2-methylbenzoate used according to the invention can impart a very complex and varied overall sensory impression, which can usually only be achieved by a mixture of several components (such as a mixture of essential oils or spices).

[0014] In addition to the primary, i.e. olfactory, properties, ethyl 2-methylbenzoate also possesses secondary properties, in particular high substantivity compared to fragrances with similar olfactory properties, high stability in certain media and preparations, high extensibility and also biodegradability.

[0015] In connection with the preferred use for imparting, modifying and / or enhancing perfume notes, ethyl 2-methylbenzoate is also recognized to perform excellent functions as a so-called booster.Preferably, ethyl 2-methylbenzoate is used as a booster of the warm notes, spicy notes and / or aromatic notes of other perfumes.In other words, by using ethyl 2-methylbenzoate together with other perfumes, their warm odor notes, spicy odor notes and / or aromatic odor notes are enhanced.

[0016] In addition, the ethyl 2-methylbenzoate used according to the present invention can increase the intensity of the perfume mixture (perfume composition) and round out the overall smell of said mixture.Therefore, the compounds described herein can be used to impart more strength, cleanliness, florality, naturalness, volume, fruitiness, freshness, spiciness, warmth, persistence, complexity, fineness, greenness, less sweatiness, less animal odor, less mushroom odor and / or less terpene odor to the perfume composition, and in particular, the compounds can be used to impart more aromaticity, spiciness and / or warmth to the perfume composition.

[0017] Furthermore, ethyl 2-methylbenzoate is suitable as an agent for increasing the substantivity and / or staying power of perfume compositions.

[0018] Ethyl 2-methylbenzoate can be used in a variety of products; it can be used as a single fragrance, but it can also be particularly advantageously combined with other fragrances in different ratios to form fragrance mixtures, which can lead to the creation of new and original perfume compositions. Thus, one aspect of the present invention relates to fragrance mixtures comprising ethyl 2-methylbenzoate and optionally further components, such as solvents.

[0019] The fragrance composition according to the present invention comprises or consists of ethyl 2-methylbenzoate and at least one further fragrance. Preferably, the fragrance composition according to the present invention comprises or consists of ethyl 2-methylbenzoate and two or more further fragrances. More preferably, the fragrance composition according to the present invention comprises or consists of ethyl 2-methylbenzoate and three or more further fragrances. Most preferably, the fragrance composition according to the present invention comprises or consists of ethyl 2-methylbenzoate and four or more further fragrances.

[0020] The ethyl 2-methylbenzoate according to the invention is usually used in an organoleptically effective amount, ie in a total amount which exerts an organoleptic effect.

[0021] Preferably, the weight ratio of ethyl 2-methylbenzoate to the total amount of further flavourings is in the range of from 1:10 to 1:100, preferably from 1:25 to 1:50.

[0022] In this context, it is preferred that the total amount of ethyl 2-methylbenzoate is 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, 0.01 to 90% by weight, 0.01 to 50% by weight, 0.01 to 20% by weight, particularly preferably from 0.01 to 1.5% by weight and in particular from 0.01 to 1.0% by weight, in each case based on the total weight of the composition.

[0023] In a preferred embodiment according to the invention, ethyl 2-methylbenzoate is present in said fragrance composition in an organoleptically effective amount sufficient to modify an existing fragrance to make said fragrance stronger, cleaner, more floral, more natural, more voluminous, more fruity, more fresh, longer-lasting, more complex, more delicate, more green, less sweaty, less animalic, less mushroomy and / or less terpenic, and / or to enhance aromatic and / or spicy fragrance notes.Thus, in a preferred embodiment according to the invention, ethyl 2-methylbenzoate is preferably combined with at least one aromatic and / or spicy fragrance in the fragrance composition.
