Background Art

[0002] Aroma chemicals, especially perfumes, are of great interest especially in the fields of cosmetics and cleaning and laundry compositions.

[0003] The market for aroma chemicals is constantly changing. Customers and retailers are constantly looking for new perfumes that meet current trends. However, the development of new perfumes is a risky and expensive business. New products have to be carefully characterized, the developed routes have to be economically viable, and the final products have to be biodegradable and toxicologically harmless. From a sustainability perspective, it would also be advantageous if existing and established perfumes could simply be modified rather than having to be completely re-developed each time. Additionally or alternatively, it would be advantageous if the intensity of existing perfume components could be increased in a simple way so that less material could be used.

[0004] Therefore, the object of the present invention is to find a way to enhance and / or modify the aroma of known aroma chemicals. In addition, the substance used for this purpose should combine well with the known aroma chemicals, be economically available, environmentally friendly, and toxicologically harmless.

[0005] EP 099844B1 relates to a process for the preparation of 4-tert-butylcyclohexyl acetate, which has a woody and fruity fragrance and is used as a perfume in soaps, detergents or shampoos. The acetate will have a cis-isomer content of at least 90% and will contain less than 50 ppm of acetic acid, since it is stated that the desired fragrance cannot be obtained if the content of acetic acid exceeds 50 ppm. In the comparative example, 4-tert-butylcyclohexyl acetate containing 94 ppm of acetic acid was prepared.

[0006] Surprisingly, it has been found that when used in certain concentrations, acetic acid advantageously enhances and / or modifies the aroma, in particular the fragrance, of known aroma chemicals having an acetate or propionate group. By way of example only, in the case of 1,4-butanediol diacetate, its fragrance is enhanced by the presence of a certain concentration of acetic acid and is also perceived as more natural or "greener". This advantageous effect is observed when both acetic acid and the corresponding aroma chemical are mixed and when, in the preparation, purification or separation process of an aroma chemical having one or more acetate groups, the resulting product contains a certain amount of acetic acid. Summary of the Invention

[0007] The present invention relates to the use of acetic acid for enhancing and / or modifying the aroma, preferably the fragrance, of aroma chemicals (I) containing one or more acetate or propionate groups (i.e., acetic acid ester or propionic acid ester groups) or mixtures of different aroma chemicals (I), wherein acetic acid is used in an amount of 50 to 600 ppm relative to the total weight of acetic acid and said one or more aroma chemicals (I).

[0019] definition:

[0020] In the context of the present invention, the term "aromatic" refers to sensory properties and includes odor and / or flavor.

[0021] The term "aromatic chemical" refers to a substance used to obtain an aromatic effect (the term "aromatic effect" is used interchangeably with the term "fragrance note" herein) and includes its use for obtaining an olfactory and / or flavor effect. The term "olfactory effect" or "odor effect" refers to an odor effect without any positive or negative judgment, while the terms "aromatic effect" or "fragrance effect" (used interchangeably herein) as used herein relate to an odor effect that is generally pleasant. Thus, "fragrance" or "aroma" refers to an aromatic chemical that mainly causes a pleasant odor effect. Flavor refers to an aromatic chemical that causes a taste effect.

[0022] The term "aromatic property" refers to the overall aromatic effect of an aromatic chemical and is constituted by the individual aromatic effects of the aromatic chemical.

[0023] The term "aromatic composition" as used herein refers to a composition that causes an aroma. The term aromatic composition includes an "odor composition" and / or a "flavor composition". An odor composition is a composition that mainly causes an odor effect, while a flavor composition is a composition that mainly causes a taste effect.

[0024] The term "odor composition" includes a "fragrance composition" or an "aroma composition" (used interchangeably herein), which mainly causes an odor effect that is generally pleasant.

[0025] "Pleasant odor", "pleasant odor effect", "pleasant odor characteristic", "odor effect that is felt to be pleasant", and similar terms are all expressions of pleasure that describe the pleasantness and clarity of the odor effect conveyed by an aromatic chemical. The more general expression of pleasure, "favorable sensory characteristic" or "favorable sensory property", describes the pleasantness and clarity of the sensory effect conveyed by an aromatic chemical. For the purposes of the present invention, the terms "sensory" and "sensory" relate to olfactory or flavor characteristics. "Pleasantness" and "clarity" are terms familiar to those skilled in the art (perfumers). Pleasantness generally refers to a spontaneously induced, positively perceived, pleasant sensory effect. However, "pleasant" is not necessarily synonymous with "sweet". "Pleasant" can also be the odor of musk or sandalwood. "Clarity" generally refers to a spontaneously induced sensory effect that, for the same test panel, reproducibly evokes the same specific thing. For example, a substance can have an odor that spontaneously evokes "apple": the odor will then clearly be "apple". If the apple odor is very pleasant because the odor evokes, for example, a sweet, fully ripe apple, then the odor will be called "pleasant". However, the odor of a typical sour apple can also be clear. If two reactions occur after smelling the substance, in this instance therefore a pleasant and clear apple odor, then the substance has particularly favorable sensory properties.

[0026] The term "odor - intense substance" refers to a substance or an aroma chemical that exhibits a strong odor effect. A strong odor effect should be understood to mean those properties of an aroma chemical that allow for an obvious perception even at very low gas - space concentrations.

[0027] The intensity can be determined via threshold determination. The threshold is the concentration of the substance in the relevant gas space at which a representative test panel can just still perceive the odor effect, although the odor effect no longer needs to be defined. Substance classes that may belong to the class of the most odor - intense known substances (i.e., having a very low odor threshold) are thiols, whose thresholds are typically in the ppb / m 3 range.

[0028] However, in the context of enhancing the aroma of an aroma chemical (I) by acetic acid (alternatively expressed: enhancing the intensity of its aroma), the intensity is a relative value determined compared to the base aroma of the aroma chemical (I) without acetic acid (or with an acetic - acid amount below the lower limit of the said range).

[0029] The term "enhancing the aroma of an aroma chemical (I) containing one or more acetate or propionate groups" should thus be understood as enhancing the aroma characteristics (i.e., feeling the aroma as stronger and more intense) of the aroma chemical (I) compared to the said aroma chemical (I) without acetic acid (or with an acetic - acid amount below the lower limit of the said range). Compared to the said aroma chemical (I) without acetic acid (or with an acetic - acid amount below the lower limit of the said range), the enhancement can be 10%, 20%, 30%, 40%, 50% or more. In one embodiment, the enhancement is at least 80% or at least 100%.

[0030] The expression "altering the aroma of an aroma chemical (I) containing one or more acetate or propionate groups" should be understood as altering its aroma characteristics or attributes compared to the said aroma chemical (I) without acetic acid (or with an acetic - acid amount below the lower limit of the said range). This alteration makes the aroma continue to feel pleasant and agreeable. In particular, acetic acid is not perceived because the substance is usually felt as unpleasant or even corrosive. By way of example only, adding acetic acid in the said amount to 1,4 - butanediol diacetate changes the latter's aroma from a fruity - sweet type to a more natural and greener character. Such an aroma alteration is beneficial, for example, for household - care compositions such as laundry detergents, where a natural green aroma is usually associated with cleanliness.

[0031] The more general terms "booster", "boosting" or "boost" are used herein to describe the action of enhancing and / or altering the aroma of an aroma chemical or a composition. The term "enhancing" includes an improvement in the pleasantness and / or clarity and / or intensity of the aroma. The term "altering" includes an alteration of the aroma attributes.

[0032] When applications featuring top notes are required, where the odor needs to be transmitted particularly quickly and strongly, a promoter effect is particularly desired in the fragrance composition, for example in deodorants, air fresheners or in the flavoring part of chewing gum.

[0033] The term "persistence" describes the evaporation behavior of aroma chemicals over time. Persistence can be determined, for example, by applying the aroma chemical to a test strip and subsequently performing an olfactory evaluation of the odor effect of the test strip. For aroma chemicals with high persistence, the panel can still identify that the time span of the aroma effect is long.

[0034] The term "fastness" describes the interaction of aroma chemicals with surfaces (such as skin or textiles), especially after subsequent treatment of the surface (such as washing). Fastness can be determined, for example, by washing a textile with a textile detergent composition containing the aroma chemical and then performing an olfactory evaluation of the textile (wet textile) directly after washing and of the dry textile after long-term storage.

[0035] The term "stability" describes the behavior of aroma chemicals upon contact with oxygen, light and / or other substances. Aroma chemicals with high stability retain their aromatic properties over a long period of time, preferably in various compositions and under various storage conditions.

[0036] In order to impart a persistent aromatic effect to a composition or to a surface treated with the composition, the persistence, fastness and stability of the aroma chemicals in the composition should preferably be high.

[0037] The terms "compound" and "substance" are used synonymously throughout the present invention.

[0038] In the context of the present invention, the term "acetate group" relates to the acetate group (-O-C(=O)-CH3) (and not to the salts of acetic acid), and the term "propionate group" relates to the propionate group (-O-C(=O)-CH2CH3) (and not to the salts of propionic acid). Aroma chemicals (I) containing one or more acetate or propionate groups thus contain one or more acetylated or propionylated hydroxyl groups.

[0039] Unless otherwise stated, where the amount or concentration of a component is given in "ppm", this corresponds to 1 g of the component / 1,000,000 g of the reference system (or 1 mg / kg). Thus, 1 ppm corresponds to 0.0001% by weight relative to the reference system. Thus, 1 ppm of acetic acid corresponds to 0.0001% by weight relative to the total weight of one or more aroma chemicals (I) and acetic acid.

[0040] Unless otherwise stated or apparent from the context, the following comments on preferred embodiments regarding various features (such as the amount of acetic acid, aroma chemicals containing acetate or propionate groups, etc.) apply to the context of the uses and methods of the present invention and to the context of the compositions of the present invention.

[0137] The companies from which the above-listed aroma chemical compounds, which can be identified by trade name and index, can be obtained are listed below.

[0138] Acetic acid is used in an amount of preferably 70 to 600 ppm, more preferably 70 to 550 ppm, even more preferably 80 to 500 ppm, such as 80 to 150 ppm or 100 to 550 ppm or 100 to 500 ppm or 150 to 500 ppm or 150 to 400 ppm, or 200 to 300 ppm relative to the total weight of acetic acid and said one or more aroma chemicals (I) for enhancing and / or modifying the aroma, preferably the fragrance, of the aroma chemical (I) containing one or more acetate or propionate groups or for enhancing and / or modifying the aroma, preferably the fragrance, of a mixture of different aroma chemicals (I).

[0139] Similarly, in a composition used as an aromatic composition, preferably as a perfume and containing acetic acid and at least one aroma chemical (I) containing one or more acetate or propionate groups, acetic acid is comprised in an amount of preferably 50 to 600 ppm, preferably 70 to 600 ppm, more preferably 70 to 550 ppm, even more preferably 80 to 500 ppm, such as 80 to 150 ppm or 100 to 550 ppm or 100 to 500 ppm or 150 to 500 ppm or 150 to 400 ppm, or 200 to 300 ppm relative to the total weight of acetic acid and said one or more aroma chemicals (I).

[0140] As already explained above, the term "acetate group" relates to an acetic acid ester group (-O-C(=O)-CH3) (and not to a salt of acetic acid), and the term "propionate group" relates to a propionic acid ester group (-O-C(=O)-CH2CH3) (and not to a salt of propionic acid). Thus, the aromatic chemical (I) containing one or more acetate or propionate groups is an ester of acetic acid or propionic acid.

The esterification can be carried out in the presence of an esterification catalyst; this is particularly indicated if a carboxylic acid itself is used. Suitable esterification catalysts are well known in the art and are, for example, metal-based catalysts such as iron, cadmium, cobalt, lead, zinc, antimony, magnesium, titanium and tin catalysts in the form of metals, metal oxides or metal salts such as metal alkoxides; or acids, for example inorganic acids such as sulfuric acid, hydrochloric acid or phosphoric acid; organic sulfonic acids such as methanesulfonic acid or p-toluenesulfonic acid, or strongly acidic cation exchange resins. After completion of the reaction, the esterification product can be separated by conventional means, if necessary, after neutralization (especially if an acyl halide or acid anhydride is used as starting material or if an excess of acid is used) and / or after removal of the catalyst (especially if the catalyst is a solid, such as one of the above-mentioned metal-based catalysts or ion exchange resins), for example by distillation, extraction or chromatography. If desired, the separated product can then be further purified. The purification can be carried out, for example, by distillation. If an acetate has been prepared, distillation can be carried out to obtain a composition containing the desired ester and the desired amount of acetic acid.

[0233] Specifically, a mixture of 2-phenylethyl acetate and acetic acid in an amount of 50 to 600 ppm or 70 to 600 ppm or 70 to 550 ppm or 80 to 500 ppm or 80 to 300 ppm or 100 to 200 ppm, such as 50 ppm or 100 ppm or 200 ppm or 500 ppm, relative to the total weight of 2-phenylethyl acetate and acetic acid, is used to impart to the compositions listed above one of the following olfactory notes: floral, rose, sweet, honey, fruit, tropical; or any combination thereof.

[0234] In addition to the olfactory properties, the combination of acetic acid at a given concentration and at least one aroma chemical (I) containing one or more acetate or propionate groups exhibits advantageous secondary properties.

[0235] For example, due to the synergistic effect with other fragrances, it can provide better sensory properties, which means it can provide a promoter effect for other fragrances. Therefore, it is suitable as a promoter for other fragrances.

[0236] Therefore, another aspect of the present invention relates to the use of a combination (usually a mixture) of acetic acid at a given concentration and at least one aroma chemical (I) containing one or more acetate or propionate groups for modifying the aroma characteristics of a perfumed composition; and specifically to the use as a promoter for other fragrances.

[0237] The promoter effect means that a substance enhances and intensifies the overall effect of the mixture in a perfumery formulation. In the mint series, for example, it is known that menthyl methyl ether enhances the perfumery or flavor mixture of peppermint oil and in particular brings a significantly stronger and more complex perception in the top note, although the ether itself as a pure substance does not produce a particularly strong odor. In fragrance applications, Methyl dihydrojasmonate, as a pure substance, only exhibits a faint jasmine floral note, and as an odor promoter, it enhances the diffusion, freshness and volume of a perfume composition. The promoter effect is particularly desirable when an application characterized by a top note is required, where the odor effect needs to be transmitted particularly quickly and strongly, such as in deodorants, air fresheners or in the flavoring part of chewing gum.

[0238] To achieve this promoter effect, a composition containing acetic acid at a given concentration and an aroma chemical (I) containing one or more acetate or propionate groups is generally used in an amount of 0.1% to 20% by weight, preferably 0.5% to 10% by weight, particularly 0.6% to 5% by weight, of the aroma chemical (I) containing one or more acetate or propionate groups, based on the total weight of the fragrance mixture.

[0239] Furthermore, a combination of acetic acid at a given concentration and the at least one aroma chemical (I) containing one or more acetate or propionate groups can have a further positive effect on the composition in which it is used. For example, it can enhance the overall properties of the composition in which it is incorporated, such as the stability of the composition (e.g., formulation stability), extensibility or persistence.

[0240] Furthermore, the present invention relates to a method for enhancing and / or modifying the aroma, preferably the fragrance, of an aroma chemical (I) containing one or more acetate or propionate groups or a mixture of two or more different aroma chemicals (I), which comprises providing a composition containing the at least one aroma chemical (I) and acetic acid in an amount of 50 to 600 ppm, preferably 70 to 600 ppm, more preferably 70 to 550 ppm, even more preferably 80 to 500 ppm, such as 80 to 150 ppm or 100 to 500 ppm or 150 to 500 ppm or 150 to 400 ppm or 200 to 300 ppm, relative to the total weight of acetic acid and the aroma chemical (I). Suitable and preferred aroma chemicals are those listed above in the context of the use according to the invention.

[0241] The method preferably comprises adding acetic acid to the one or more aroma chemicals (I) in an amount such that a composition is obtained which contains the one or more aroma chemicals (I) and acetic acid in an amount of 50 to 600 ppm, preferably 70 to 600 ppm, more preferably 70 to 550 ppm, even more preferably 80 to 500 ppm, such as 80 to 150 ppm or 100 to 500 ppm or 150 to 500 ppm or 150 to 400 ppm or 200 to 300 ppm, relative to the total weight of acetic acid and the one or more aroma chemicals (I);

[0242] Alternatively, in the case where the one or more aroma chemicals (I) contain one or more acetate groups prepared using acetic acid or its derivatives, the reaction, purification and / or separation conditions in the preparation process of the one or more aroma chemicals (I) are adjusted so as to obtain a composition containing the one or more aroma chemicals (I) and acetic acid in an amount of 50 to 600 ppm, preferably 70 to 600 ppm, more preferably 70 to 550 ppm, even more preferably 80 to 500 ppm, such as 80 to 150 ppm or 100 to 500 ppm or 150 to 500 ppm or 150 to 400 ppm or 200 to 300 ppm, relative to the total weight of acetic acid and the one or more aroma chemicals (I).

[0243] Most conveniently, the conditions of the final purification step are adjusted so as to obtain a composition containing the one or more aroma chemicals and acetic acid at the desired concentration.

Alternatively, the present invention relates to a process for altering the aroma profile of an aroma chemical composition, in particular a perfuming composition, especially a ready-to-use perfuming composition, which comprises mixing at least one aroma chemical (I) containing one or more acetate or propionate groups and acetic acid, simultaneously or continuously, with the other components of the composition or with a preformed mixture of a part of the other components of the composition, the amount of acetic acid being such that it is present in the composition in an amount of 50 to 600 ppm, preferably 70 to 600 ppm, more preferably 70 to 550 ppm, even more preferably 80 to 500 ppm, such as 80 to 150 ppm or 100 to 500 ppm or 150 to 500 ppm or 150 to 400 ppm or 200 to 300 ppm, relative to the total weight of acetic acid and said aroma chemical (I).

[0366] According to a further embodiment, according to the invention, the at least one aroma chemical (I) is used in combination with a given amount of acetic acid in a surfactant-containing composition. Due to its characteristic aroma properties and its robustness, persistence and stability, the combination of the at least one aroma chemical (I) and the said amount of acetic acid can in particular be used to impart an odor, preferably a fragrance effect, to a surfactant-containing composition (such as, for example, a cleaning agent (especially a laundry care product and a general-purpose cleaning agent)).

[0367] Accordingly, one embodiment of the invention relates to a composition comprising at least one aroma chemical (I) containing one or more acetate or propionate groups as defined above, the said amount of acetic acid and at least one surfactant.

[0368] The one or more surfactants can be selected from anionic, nonionic, cationic and / or amphoteric or zwitterionic surfactants. The surfactant-containing composition (such as, for example, a shower gel, a foam bath, a shampoo, etc.) preferably contains at least one anionic surfactant.

[0409] Deodorant active agent

[0410] One embodiment of the invention relates to a composition comprising at least one aromatic chemical (I) containing one or more acetate or propionate groups as defined above, said amount of acetic acid, and at least one deodorizing active agent.

[0411] The at least one aromatic chemical (I) containing one or more acetate or propionate groups as defined above, together with said amount of acetic acid, can be used to impart a clean, long-lasting fragrance to deodorant compositions and to skin treated with such compositions.

[0412] Deodorant compositions (deodorants and antiperspirants) counteract, mask, or eliminate body odor. Body odor is formed by the action of skin bacteria on apocrine sweat, which results in the formation of degradation products with unpleasant odors.

[0413] In a preferred embodiment of the invention, the at least one deodorizing active agent is selected from the group consisting of antiperspirants, esterase inhibitors, and antibacterial agents.

[0414] Suitable antiperspirants may be selected from the group consisting of salts of aluminum, zirconium or zinc. Examples are aluminum chloride, aluminum chloride hydrate, aluminum dichloride hydrate, aluminum sesquichloride hydrate and their complex compounds (e.g., with 1,2 - propanediol), aluminum hydroxyallantoin, aluminum chloride tartrate, zirconium aluminum trichloride hydrate, zirconium aluminum tetrachloride hydrate, zirconium aluminum pentachloride hydrate and their complex compounds (e.g., with amino acids such as glycine). Aluminum chloride hydrate, zirconium aluminum tetrachloride hydrate, zirconium aluminum pentachloride hydrate and their complex compounds are preferably used.

[0415] In a preferred embodiment of the invention, these compositions comprise at least one antiperspirant selected from the group consisting of aluminum chloride, aluminum chloride hydrate, aluminum dichloride hydrate, aluminum sesquichloride hydrate, aluminum hydroxyallantoin, aluminum chloride tartrate, zirconium aluminum trichloride hydrate, zirconium aluminum tetrachloride hydrate and zirconium aluminum pentachloride hydrate.

[0417] When sweat is present in the axillary region, extracellular enzymes - esterases, mainly proteases and / or lipases, are formed by bacteria and decompose the esters present in the sweat, releasing odor in the process. Suitable esterase inhibitors are, for example, trialkyl citrates such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate, and especially triethyl citrate. The esterase inhibitor inhibits the enzyme activity and thus reduces odor formation. Free acids may be released by cleavage of the citrate ester and lower the pH value of the skin to an extent where the enzyme is inactivated by acylation. Other esterase inhibitors are sterol sulfates or phosphates, such as lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfates or phosphates, dicarboxylic acids and their esters, such as glutaric acid, monoethyl glutarate, diethyl glutarate, adipic acid, monoethyl adipate, diethyl adipate, malonic acid and diethyl malonate, hydroxycarboxylic acids and their esters, such as citric acid, malic acid, tartaric acid or diethyl tartrate, and zinc glycinate.

[0418] In a preferred embodiment of the invention, these compositions comprise at least one esterase inhibitor selected from the group consisting of trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate, triethyl citrate, lanosterol, cholesterol, campesterol, stigmasterol, sitosterol sulfate, sitosterol phosphate, glutaric acid, monoethyl glutarate, diethyl glutarate, adipic acid, monoethyl adipate, diethyl adipate, malonic acid, diethyl malonate, citric acid, malic acid, tartaric acid, diethyl tartrate and zinc glycinate.

[0419] The composition according to the invention may comprise an esterase inhibitor in an amount of from 0.01 wt.-% to 20 wt.-%, preferably from 0.1 wt.-% to 10 wt.-% and more particularly from 0.5 wt.-% to 5 wt.-%, based on the solids content of the composition.

All these hydrolases contribute to the dissolution and removal of dirt from protein-, grease- or starch-containing stains / residues. For bleaching, redox enzymes can also be used.

[0455] The polyvalent chelating agents of component (e), also known as builders, structuring agents, framework substances, complexing agents, chelates, chelating agents or softeners, bind alkaline earth metals and other water-soluble metal salts without precipitation. They contribute to the destruction of dirt, disperse dirt components, help to separate dirt and in some cases they themselves have a washing effect. Many polyvalent chelating agents are multifunctional, meaning that these substances have additional functions, such as dispersing activity or anti-greying properties. Suitable polyvalent chelating agents can be organic or inorganic in nature. Examples are aluminosilicates, carbonates, phosphates and polyphosphates, polycarboxylic acids, polycarboxylates, hydroxycarboxylic acids, phosphonic acids such as hydroxyalkylphosphonic acids, phosphonates, aminopolycarboxylic acids and their salts, and polymeric compounds containing carboxylic acid groups and their salts. More specific examples of inorganic polyvalent chelating agents are crystalline or amorphous aluminosilicates with ion-exchange properties, such as zeolites; disilicates or phyllosilicates; carbonates and bicarbonates, usually in the form of their alkali metal, alkaline earth metal or ammonium salts; alkali metal orthophosphates and / or polyphosphates, such as sodium tripolyphosphate.

[0456] The defoamers and / or foam stabilizers of component (f) are, for example, soaps, paraffins and silicone oils.

[0457] The pH regulators of the composition (g) are acids, bases and buffer systems. The acids can be inorganic or organic.

Suitable organic acids are, for example, aliphatic, saturated unsubstituted C1-C6 mono-, di- and tricarboxylic acids such as formic acid, acetic acid, propionic acid, oxalic acid, succinic acid and glutaric acid; aliphatic, saturated C1-C6 mono-, di- and tricarboxylic acids with one or more OH groups such as lactic acid, tartaric acid and citric acid; aliphatic, unsaturated C1-C6 mono-, di- and tricarboxylic acids such as sorbic acid; aromatic carboxylic acids such as benzoic acid, salicylic acid and mandelic acid; and sulfonic acids such as methanesulfonic acid or toluenesulfonic acid. Organic acids are mainly used to adjust the pH of the composition, but some of them, such as di- and tricarboxylic acids, can also act as multivalent chelating agents. Suitable bases are especially inorganic bases such as carbonates mentioned in the context of multivalent chelating agents, such as sodium carbonate or potassium carbonate; further alkali metal and alkaline earth metal hydroxides such as NaOH or KOH. Suitable buffers are typical systems such as hydrogen phosphate / dihydrogen phosphate buffers, carbonate / bicarbonate buffers, acetic acid / acetate buffers or Tris buffers. In addition, most of the above-mentioned weak acids whose anions are not strong salts also have buffering capacity.

[0458] Examples of further additives (h) are antimicrobial agents (including preservatives), fragrances different from (b), hydrotropes, enzyme stabilizers, bleaching agents, corrosion inhibitors, dyes, thickeners, activity enhancers and inorganic salts.

[0459] If the composition is liquid or gel-like, it must contain water, usually in an amount of 10% to 99.89% by weight relative to the total weight of the composition. In liquid ready-to-use compositions (ready-to-use compositions are compositions that are used as they are and do not require any further dilution or addition of additional substances), the amount of water is usually in the range of 30% to 99.89% by weight, usually 40% to 99% by weight, relative to the total weight of the composition.

In shampoos and shower gels, it is useful to use surfactants that are good foam formers. In addition, shampoo or shower gel compositions may contain nonionic, amphoteric and / or cationic co-surfactants, which help to impart aesthetic, tactile, combing, physical or cleaning properties to the composition.

[0480] Other components that may be present in a shampoo or shower gel are, for example, suspending agents such as polyacrylic acid, crosslinked polymers of acrylic acid, copolymers of acrylic acid and hydrophobic monomers, copolymers containing carboxylic acid monomers and acrylates, crosslinked copolymers of acrylic acid and acrylates, heteropolysaccharide gums and crystalline long-chain acyl derivatives, the latter preferably being selected from ethylene glycol stearate, alkanolamides of fatty acids having 16 to 22 carbon atoms and mixtures thereof; perfumes, dyes and pigments different from 1,4-butanediol mono- and diacetate, pH regulators, preservatives, pearlescing or opacifying agents, viscosity regulators and salts such as NaCl; in shampoos there are also conditioning agents, natural hair nutrients or dermatologically active ingredients such as plant preparations, fruit extracts, caffeine, panthenol, sugar derivatives, amino acids such as hydrolyzed keratin or glycine, vegetable or hydrogenated vegetable oils.

[0481] The fragrance chemical (I) containing one or more acetate or propionate groups and acetic acid can simply be processed into a composition by directly mixing them with a basic composition that is only lacking this / these compounds. Alternatively, the fragrance chemical (I) containing one or more acetate or propionate groups and acetic acid can be mixed simultaneously or continuously with other components of the composition or with a pre-formed mixture of a part of the other components.

[0482] The fragrance chemical (I) containing one or more acetate or propionate groups and acetic acid can be intercepted in an earlier step with, for example, the following interception materials: polymers, capsules, microcapsules and nanocapsules, liposomes, film-forming agents, absorbents (such as carbon or zeolites), cyclodextrins and mixtures thereof, or can be chemically bound to a substrate that is suitable for releasing the compound (I) upon application of an external stimulus such as light, enzymes, etc., and then mixed with the composition.

[0483] The fragrance chemical (I) containing one or more acetate or propionate groups and acetic acid or a composition containing these compounds according to the invention can also be in the form of microcapsules, spray-dried form, inclusion complex form or extruded product form. With regard to a more targeted release of the fragrance, these properties can be further optimized with a suitable material by means of so-called "coating", for which purpose, waxy synthetic substances such as polyvinyl alcohol are preferably used.

[0484] Microencapsulation can be carried out, for example, by means of the so-called coacervation method with the aid of a capsule material (such as that made of polyurethane substances or soft gelatin). Spray-dried perfume oils can be produced, for example, by spray-drying an emulsion or dispersion comprising an aroma chemical (I) containing one or more acetate or propionate groups and acetic acid or the composition of the present invention described herein, wherein the carrier substances that can be used are modified starches, proteins, dextrins, and vegetable gums. Inclusion complexes can be prepared, for example, by introducing a dispersion of a fragrance composition and a cyclodextrin or urea derivative into a suitable solvent such as water. Extruded products can be produced by melting an aroma chemical (I) containing one or more acetate or propionate groups, or the composition of the present invention described herein, with a suitable waxy substance and extruding, followed by curing, optionally in a suitable solvent such as isopropyl alcohol.

[0485] Generally, the total amount of one or more aroma chemicals containing one or more acetate or propionate groups in the composition according to the present invention is typically adapted to the specific intended use or application and can thus vary within a wide range. Generally, conventional standard commercial amounts for fragrances are used.

[0486] The composition according to the present invention can comprise from 0.001% to 99.9% by weight, preferably from 0.01% to 90% by weight, more preferably from 0.01% to 80% by weight, particularly from 0.01% to 60% by weight, more particularly from 0.01% to 40% by weight, for example from 0.01% to 10% by weight or from 0.01% to 15% by weight or from 0.01% to 5% by weight or from 0.05% to 5% by weight of the total amount of aroma chemicals (I) containing one or more acetate or propionate groups, based on the total weight of the composition.

[0487] In one embodiment of the present invention, the composition comprises from 0.001% to 10% by weight or from 0.001% to 5% by weight, preferably from 0.01% to 2% by weight or from 0.05% to 5% by weight of the total amount of aroma chemicals (I) containing one or more acetate or propionate groups, based on the total weight of the composition.

[0488] Furthermore, the present invention relates to a method for preparing an aromatic chemical composition, in particular a perfuming composition, specifically a ready-to-use perfuming composition, which comprises incorporating into said composition at least one aromatic chemical (I) containing one or more acetate or propionate groups as defined above and acetic acid, the amount of acetic acid being such that it is present in said composition in an amount of 50 to 600 ppm, preferably 70 to 600 ppm, more preferably 70 to 550 ppm, even more preferably 80 to 500 ppm, for example 80 to 150 ppm or 100 to 500 ppm or 150 to 400 ppm or 200 to 300 ppm relative to the total weight of acetic acid and said one or more aromatic chemicals; or mixing at least one aromatic chemical (I) containing one or more acetate or propionate groups as defined above and acetic acid, simultaneously or continuously, with other components of said composition or with a preformed mixture of a part of other components of said composition, the amount of acetic acid being such that it is present in the resulting composition in an amount of 50 to 600 ppm, preferably 70 to 600 ppm, more preferably 70 to 550 ppm, even more preferably 80 to 500 ppm, for example 80 to 150 ppm or 100 to 500 ppm or 150 to 400 ppm or 200 to 300 ppm relative to the total weight of acetic acid and said one or more aromatic chemicals.

[0489] The present invention also relates to a method for imparting aroma, preferably fragrance, to a composition, which comprises incorporating into said composition at least one aromatic chemical (I) containing one or more acetate or propionate groups as defined above and acetic acid, the amount of acetic acid being such that it is present in said composition in an amount of 50 to 600 ppm, preferably 70 to 600 ppm, more preferably 70 to 550 ppm, even more preferably 80 to 500 ppm, for example 80 to 150 ppm or 100 to 500 ppm or 150 to 400 ppm or 200 to 300 ppm relative to the total weight of acetic acid and said one or more aromatic chemicals; or comprising mixing at least one aromatic chemical (I) containing one or more acetate or propionate groups as defined above and acetic acid, simultaneously or continuously, with other components of said composition or with a preformed mixture of a part of other components of said composition, the amount of acetic acid being such that it is present in the resulting composition in an amount of 50 to 600 ppm, preferably 70 to 600 ppm, more preferably 70 to 550 ppm, even more preferably 80 to 500 ppm, for example 80 to 150 ppm or 100 to 500 ppm or 150 to 400 ppm or 200 to 300 ppm relative to the total weight of acetic acid and said one or more aromatic chemicals.

[0490] The aroma, in particular the fragrance, of an aromatic chemical (I) containing one or more acetate or propionate groups is enhanced by the acetic acid of said concentration / amount. In some cases, acetic acid also modifies the aromatic characteristics, in particular the odor characteristics, and in particular makes the characteristics fresher and greener. Acetic acid is a bulk chemical that is abundantly available, can be obtained from renewable sources, is very economical, and is environmentally and toxicologically harmless.

[0491] The following examples serve as further illustration of the present invention.

[0492] Examples

[0493] abbreviation:

[0494] HOAc acetic acid

[0495] Fragrance Chemicals Tested:

[0496] The following aromatic chemicals (I) were tested:

[0497] - 1,4-butanediol diacetate

[0498] - neopentyl glycol diacetate

[0499] - isoamyl acetate

[0500] - linalyl acetate

[0501] - benzyl acetate

[0502] - citronellyl acetate

[0503] - α-terpinyl acetate

[0504] - hexyl acetate

[0505] - 2-phenylethyl acetate

[0506] As described below, 1,4-butanediol diacetate and neopentyl glycol diacetate were prepared by esterifying the corresponding diols with acetic anhydride. The other aromatic chemicals (I) were purchased from Sigma Aldrich.

[0507] Preparation of 1,4-butanediol diacetate

[0508] In a 2.5 L jacketed flask equipped with a reflux condenser and an impeller stirrer, acetic anhydride (1277 g, 12.5 mol, 2.05 eq) was added and heated to 120 °C. 1,4-Butanediol (550 g, 6.10 mol, 1.00 eq) was added over 2.75 h at a rate such that the reaction temperature did not exceed 136 °C. The reaction mixture was stirred at 135 °C for an additional 2 h, resulting in complete conversion of 1,4-butanediol to 1,4-butanediol diacetate (yield: 99.4%). The reaction mixture was distilled in several steps to remove unreacted acetic anhydride and most of the acetic acid, giving the title product with an acetic acid content of 48 ppm relative to the total weight of 1,4-butanediol diacetate and acetic acid (the acetic acid content was determined by potentiometric titration to determine the acid value as described below).

[0509] Preparation of neopentyl glycol diacetate

[0510] Neopentyl glycol diacetate was prepared analogously to 1,4-butanediol diacetate.

[0511] Preparation of test samples

[0512] Before preparing the mixture with acetic acid, the commercial product (I) was subjected to a purification step (usually washing with water) to avoid impurities interfering with the aroma perception. Mixtures of the aroma chemical (I) and acetic acid in total amounts of 50 ppm, 100 ppm, 200 ppm or 500 ppm relative to the total weight of acetic acid and the aroma chemical (I) were prepared. For this purpose, the amount of acetic acid in the aroma chemical (I) was determined and then acetic acid was added to the indicated concentration.

[0513] The amount of acetic acid was determined by determining the acid value. The acid value was in turn determined by potentiometric titration: The sample was dissolved in isopropanol and titrated with a standardized tetrabutylammonium hydroxide (TBAH) solution (0.1 mol / l) in toluene / methanol.

[0514] Olfactory evaluation

[0515] A 10 wt.-% solution of the aroma chemical / acetic acid mixture in triethyl citrate (TEC) was prepared and evaluated by trained perfumers from the headspace of the sample vial and by initial adjustment on blotter ( = aroma strip). The evaluation of each sample set was carried out under blind conditions; i.e., the perfumer did not know the composition of the sample. The intensities were ranked from lowest ( = 1) to highest ( = 4) intensity within each series.

[0516] The results were compiled in the following table.

[0517] Table 1: Aroma intensities of the aroma chemical (I) / acetic acid mixture

[0518]

[0519] a Aroma description: raspberry, sweet, blueberry

[0520] b Aroma description: sweet, fresh, fruity, resinous, myrrh-like, fatty note

[0521] c Aroma description: pear, banana

[0522] d Aroma description: floral, sweet, lemon, mint and caraway note

[0523] e Aroma description: sweet, floral, fresh and slightly fruity, reminiscent of jasmine

[0524] f Aroma description: rose floral, fruity, slightly citrusy

[0525] g Aroma description: herbal, bergamot, lavender, lime, citrus

[0526] h Aroma description: fruity, green, apple, banana, sweet

[0527] i Aroma description: floral, rose, sweet, honey, fruity, tropical

[0528] * Evaluate on the smelling strip after 30 min

[0529] At any of the above concentrations, acetic acid was not perceived on the aroma strip. Only in the headspace of the vial of the sample containing 500 ppm acetic acid, a faint vinegar note (except for hexyl acetate, in which no acetic acid / vinegar note was perceived) could be faintly perceived.

[0530] As the concentration of acetic acid increased, the 1,4-butanediol diacetate / acetic acid sample was perceived as more green and more natural.
