Description

[Technical Field]

[0001] The present invention relates to the use of acetic acid to enhance and / or modify the scent, preferably fragrance, of fragrance chemicals containing one or more acetate or propionate groups (i.e., acetate ester or propionate ester groups); the use of a composition containing acetic acid and at least one fragrance chemical containing one or more acetate or propionate groups as a fragrance composition, preferably as a fragrance; the use of a composition containing acetic acid and at least one fragrance chemical containing one or more acetate or propionate groups as a fragrance composition, preferably as a fragrance; the use of a composition containing acetic acid and at least one fragrance chemical containing one or more acetate or propionate groups as a fragrance composition, preferably as a fragrance, and an acid; a composition comprising at least one fragrance chemical containing one or more acetate or propionate groups, acetic acid in an amount of 50 to 600 ppm based on the total weight of said fragrance chemicals, and at least one further ingredient selected from the group consisting of fragrance chemicals different from said fragrance chemicals containing one or more acetate or propionate groups, non-fragrance chemical carriers, antioxidants, and deodorant actives; a method for preparing a fragrance chemical composition; and a method for imparting a fragrance to a composition. [Background technology]

[0002] Perfume chemicals, especially fragrances, are of particular interest in the areas of cosmetics and cleaning and laundry compositions.

[0003] The market for fragrance chemicals is constantly changing. Customers and retailers are constantly searching for new scents that fit current trends. However, developing new scents is risky and costly. New products need to be carefully specified, the route developed must be economically viable, and the final product must be biodegradable and toxicologically harmless. From a sustainability perspective, it would be advantageous to simply modify existing, established fragrances instead of undergoing a complete redevelopment each time. Additionally or alternatively, it would be advantageous if the intensity of existing fragrance ingredients could be increased in a simple way so that fewer materials could be used.

[0004] The object of the present invention was therefore to find a method for enhancing and / or modifying the odor of known fragrance chemicals. Furthermore, the substances used for this purpose should be able to be combined without problems with said known fragrance chemicals, be economically available, be environmentally friendly and be toxicologically harmless.

[0005] EP 099844 B1 relates to a process for preparing 4-tert-butylcyclohexyl acetate, which has a woody, fruity scent and is used as a fragrance for soaps, detergents, or shampoos. The acetate should have a cis-isomer content of at least 90% and an acetic acid content of less than 50 ppm, since a desirable scent cannot be achieved with an acetic acid content of more than 50 ppm. As a comparative example, 4-tert-butylcyclohexyl acetate with an acetic acid content of 94 ppm was prepared.

[0006] Surprisingly, it has been found that acetic acid, when used at certain concentrations, advantageously enhances and / or modifies the odor, particularly the fragrance, of known fragrance chemicals having acetate or propionate groups. By way of example only, in the case of 1,4-butanediol diacetate, its odor is enhanced and also perceived as more natural or "greener" by the presence of certain concentrations of acetic acid. This advantageous effect is observed both when acetic acid is mixed with the respective fragrance chemical, and when a preparation, purification, or isolation process is carried out in the preparation of fragrance chemicals having one or more acetate groups, resulting in a certain amount of acetic acid in the resulting product. Summary of the Invention [Means for solving the problem]

[0007] The present invention relates to the use of acetic acid to enhance and / or modify the scent, preferably the fragrance, of a fragrance chemical (I) or a mixture of different fragrance chemicals (I) containing one or more acetate or propionate groups (i.e. acetate ester or propionate ester groups), wherein the acetic acid is used in an amount of 50 to 600 ppm relative to the total weight of acetic acid and said fragrance chemical (I).

[0008] Perfume chemicals containing one or more acetate or propionate groups are also abbreviated as perfume chemicals (I).

[0009] The present invention also relates to the use of a composition comprising acetic acid and at least one fragrance chemical (I) containing one or more acetate or propionate groups (i.e. acetate ester groups or propionate ester groups) as a fragrance composition, preferably as a fragrance, wherein the acetic acid is contained in an amount of 50 to 600 ppm based on the total weight of acetic acid and said fragrance chemical (I).

[0013] Perfume chemicals that are different from perfume chemical (I) and contain one or more acetate or propionate groups are also abbreviated below as perfume chemical (II).

[0014] In another aspect, the present invention relates to a method for preparing a fragrance chemical composition, comprising incorporating into the composition at least one fragrance chemical (I) containing one or more acetate or propionate groups and acetic acid in an amount such that the acetic acid is present in the composition in an amount of 50 to 600 ppm based on the total weight of acetic acid and the fragrance chemicals (I), or simultaneously or sequentially mixing with other ingredients of the composition or a preformed mixture of some of the other ingredients of the composition at least one fragrance chemical (I) containing one or more acetate or propionate groups and acetic acid in an amount such that the acetic acid is present in the resulting composition in an amount of 50 to 600 ppm based on the total weight of acetic acid and the fragrance chemicals (I). Preferably, if acetic acid is present in the resulting composition in an amount less than 100 ppm, the fragrance chemical (I) is not 4-tert-butylcyclohexyl acetate.

[0015] In yet another aspect, the present invention relates to a method for imparting a scent, preferably a fragrance, to a composition, comprising incorporating into the composition at least one fragrance chemical (I) containing one or more acetate or propionate groups and acetic acid in an amount such that the acetic acid is present in the composition in an amount of 50 to 600 ppm based on the total weight of acetic acid and said fragrance chemicals (I); or mixing simultaneously or sequentially with other ingredients of the composition or a preformed mixture of some of the other ingredients of the composition at least one fragrance chemical (I) containing one or more acetate or propionate groups and acetic acid in an amount such that the acetic acid is present in the resulting composition in an amount of 50 to 600 ppm based on the total weight of acetic acid and said fragrance chemicals (I). Preferably, if acetic acid is present in the resulting composition in an amount of less than 100 ppm, then fragrance chemical (I) is not 4-tert-butylcyclohexyl acetate. DETAILED DESCRIPTION OF THE INVENTION

[0016] Definition: In the context of the present invention, the term "aroma" refers to sensory properties and includes smell and / or flavor.

[0017] The term "fragrance chemical" means a substance used to create an odor impression (the term "aroma impression" is used interchangeably herein with the term "olfactory note"), including its use to create an olfactory and / or flavor impression. The terms "olfactory impression" or "odor impression" (used interchangeably herein) mean an odor impression without a positive or negative judgment, and as used herein, the terms "fragrance impression" or "aroma impression" (used interchangeably herein) relate to an odor impression that is generally perceived as pleasant. Thus, "fragrance" or "perfume" refers to a fragrance that primarily induces a pleasant odor impression. Flavoring refers to a fragrance that induces a taste impression.

[0018] The term "odor profile" refers to the overall odor impression of a perfume, which is made up of the individual odor impressions of the perfume.

[0019] As used herein, the term "fragrance composition" refers to a composition that elicits an aroma. The term fragrance composition includes an "odor composition" and / or a "flavor composition." An odor composition is a composition that primarily elicits an odor impression, and a flavor composition is a composition that primarily elicits a taste impression.

[0020] The term odorant composition includes "fragrance compositions" or "fragrance compositions" (used interchangeably herein) that primarily induce an odor impression that is generally perceived as pleasant.

[0021] "Pleasant odor," "pleasant odor impression," "pleasant odor characteristic," "pleasant odor impression" and similar terms are hedonic terms that describe the pleasant and distinct odor impression conveyed by a fragrance. The more general hedonic terms "favorable sensory characteristics" or "favorable organoleptic characteristics" describe the pleasant and distinct organoleptic impression conveyed by a fragrance. The terms "organoleptic" and "sensory" in the context of the present invention relate to olfactory or flavor characteristics. "Pleasantness" and "clarity" are terms well known to those skilled in the art, such as perfumers. Pleasantness generally refers to a spontaneously occurring, positively perceived pleasant sensory impression. However, "pleasant" need not be synonymous with "sweet." "Pleasant" could also be the odor of musk or sandalwood. "Clarity" generally refers to a spontaneously occurring sensory impression that reproducibly evokes something specific and identical to the same test panel. For example, if a substance has an odor that spontaneously evokes the odor of "apple," then that odor is a distinctly "apple" odor. If this apple odor is very pleasant, for example because it evokes sweet, ripe apples, then the odor is said to be "pleasant." On the other hand, the typical tart apple odor may also be distinct. If both reactions occur when smelling a substance, i.e., in this example, if it smells pleasant and distinctly apple-like, then the substance has particularly advantageous sensory properties.

[0022] The term "strong-smelling substance" refers to a substance or fragrance chemical that has a strong odor impression. Strong odor impression is understood to mean the property of a fragrance chemical that allows it to be perceived intensely even at very low gas space concentrations.

[0023] Its intensity can be measured by determining the threshold value, which no longer needs to be defined, is the concentration of a substance at which a representative test panel can still just perceive an odor impression in the relevant gas space. Among the known classes of substances, the most intense-smelling ones, i.e., those with very low odor thresholds, are probably the thiols, whose threshold is in the range of ppb / m 3 It is often an area.

[0024] However, in relation to enhancing the odor of a fragrance chemical (I) with acetic acid (alternatively expressed: increasing the intensity of that odor), intensity is a relative value determined in comparison to the base odor of fragrance chemical (I) without acetic acid (or with an amount of acetic acid below the lower limit of the stated range).

[0025] Thus, the term "enhancing the odor of a fragrance chemical (I) containing one or more acetate or propionate groups" should be understood as enhancing the odor characteristics of said fragrance chemical (I) (i.e., the odor is perceived as stronger and more intense) compared to said fragrance chemical (I) not containing acetic acid (or having an amount of acetic acid below the lower limit of the recited range). The enhancement can be 10%, 20%, 30%, 40%, 50% or more compared to said fragrance chemical (I) not containing acetic acid (or having an amount of acetic acid below the lower limit of the recited range). In one embodiment, the enhancement is at least 80% or at least 100%.

[0026] The phrase "modifying the odor of a perfume chemical (i) containing one or more acetate or propionate groups" should be understood as changing its odor characteristics or profile compared to said perfume chemical (i) without acetic acid (or with an amount of acetic acid below the lower limit of the specified range). This modification ensures that the odor remains pleasant and pleasant. In particular, acetic acid is not perceived as unpleasant or even offensive, as it is generally perceived as unpleasant or even offensive. By way of example only, adding the specified amount of acetic acid to 1,4-butanediol diacetate modifies the odor of the latter from a fruity, sweet type to a more natural, greener character. This odor modification is advantageous for home care compositions, such as laundry detergents, where natural, green odors are commonly associated with cleanliness.

[0027] The more general terms "potentiator", "potentiating" or "potentiating" are used herein to describe the effect of enhancing and / or modifying the fragrance of a fragrance chemical or composition. The term "enhancing" includes improving the pleasantness and / or clarity of the fragrance and / or improving the intensity. The term "modifying" includes changing the fragrance profile.

[0028] The effect of the potentiator is particularly desirable in fragrance compositions whose applications require a top note characterized by a particularly rapid and intensive odor delivery, for example in the taste area in deodorants, air fresheners or chewing gum.

[0029] The term "retention" describes the evaporation behavior of a fragrance chemical over time. Retention can be determined, for example, by applying a fragrance chemical to a test strip and subsequent olfactory evaluation of the odor impression of the test strip. For fragrance chemicals with high retention, the panel can still discern the fragrance impression for a long period of time.

[0030] The term "persistence" describes the interaction of perfume chemicals with a surface, such as skin or a fabric, especially after subsequent treatment of the surface (e.g., washing, etc.). Persistence can be determined, for example, by washing a fabric with a fabric detergent composition comprising perfume chemicals and then by olfactory evaluation of the fabric immediately after washing (wet fabric) and evaluation of the dried fabric after extended storage.

[0031] The term "stability" describes the behavior of a fragrance chemical when in contact with oxygen, light, and / or other substances. A highly stable fragrance chemical preferably maintains its fragrance profile over time in a variety of compositions and under various storage conditions.

[0032] Preferably, the staying power, substantivity and stability of the perfume chemicals in the composition should be high in order to impart a long-lasting fragrance impression to the composition or to surfaces treated with the composition.

[0033] The terms "compound" and "substance" are used interchangeably throughout this invention.

[0034] In the context of the present invention, the term "acetate group" refers to an acetate ester group (-O-C(=O)-CH3) (but not to salts of acetic acid) and the term "propionate group" refers to a propionate ester group (-O-C(=O)-CH2CH3) (but not to salts of propionic acid). Thus, a perfume chemical (I) containing one or more acetate or propionate groups comprises one or more acetylated or propionylated hydroxyl groups.

[0035] Unless otherwise specified, when an amount or concentration of an ingredient is given as "ppm," this corresponds to 1 g of ingredient per 1,000,000 g of reference system (or 1 mg / kg). 1 ppm therefore corresponds to 0.0001% by weight relative to the reference system. 1 ppm of acetic acid therefore corresponds to 0.0001% by weight relative to the total weight of fragrance chemical (I) and acetic acid.

[0036] Unless otherwise stated or clear from the context, the following descriptions of preferred embodiments of various features such as the amount of acetic acid, perfume chemicals containing acetate or propionate groups, etc. apply in relation to both the uses and methods of the present invention and the compositions of the present invention.

[0190] Specifically, a mixture of α-terpinyl acetate with 50 to 600 ppm, or 70 to 600 ppm, or 70 to 550 ppm, or 80 to 500 ppm, or 150 to 500 ppm, or 150 to 400 ppm, or 200 to 300 ppm, for example 50 ppm, or 100 ppm, or 200 ppm, or 500 ppm, of acetic acid, based on the total weight of α-terpinyl acetate and acetic acid, is used to impart one of the following olfactory notes to the above-listed compositions: herbal, bergamot, lavender, lime, citrus, or any combination thereof.

[0191] Specifically, a mixture of hexyl acetate with 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, for example 50 ppm, or 100 ppm, or 200 ppm, or 500 ppm, of acetic acid, based on the total weight of hexyl acetate and acetic acid, is used to impart one of the following olfactory notes to the above-listed compositions: fruity, green, apple, banana, sweet, or any combination thereof.

[0192] Specifically, a mixture of 2-phenylethyl acetate with 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, for example 50 ppm, or 100 ppm, or 200 ppm, or 500 ppm of acetic acid, based on the total weight of 2-phenylethyl acetate and acetic acid, is used to impart one of the following olfactory notes to the above-listed compositions: floral, rose, sweet, honey, fruity, tropical, or any combination thereof.

[0193] In addition to the olfactory properties, the combination of a given concentration of acetic acid with at least one perfume chemical (I) containing one or more acetate or propionate groups exhibits advantageous secondary properties.

[0194] For example, it can impart a better sensory profile as a result of synergistic interaction with other fragrances, which means that it has the effect of enhancing other fragrances, and is therefore suitable as an enhancer for other fragrances.

[0195] Therefore, another aspect of the present invention relates to the use of a combination (generally a mixture) of a given concentration of acetic acid with at least one perfume chemical (I) containing one or more acetate or propionate groups, in order to modify the odor characteristics of a perfumed composition, in particular as an enhancer of other fragrances.

[0196] The enhancer effect means that in perfume formulations, a substance improves and intensifies the overall impression of the mixture. For example, in the mint field, menthyl methyl ether is known to enhance the fragrance chemicals or flavor mixture of peppermint oil, significantly strengthening the top notes and creating a more complex perception, even though the ether itself does not have a particularly strong odor. In fragrance applications, Hedione® (methyl dihydrojasmonate) exhibits only a light jasmine floral note on its own, but as an odor enhancer, it enhances the diffusion, freshness, and volume of perfume compositions. The enhancer effect is particularly desirable in applications requiring a top note characterized by particularly rapid and intense odor delivery, such as in deodorants, air fresheners, or the taste field of chewing gum.

[0197] To achieve such an enhancing effect, compositions containing a given concentration of acetic acid and perfume chemicals (I) containing one or more acetate or propionate groups generally use an amount of 0.1 to 20% by weight, preferably 0.5 to 10% by weight, especially 0.6 to 5% by weight, of perfume chemicals (I) containing one or more acetate or propionate groups, based on the total weight of the fragrance mixture.

[0198] Furthermore, the combination of a given concentration of acetic acid with at least one perfume chemical (I) containing one or more acetate or propionate groups can have additional positive effects on the composition it is used in. For example, it can improve the overall performance of the composition in which the compound is incorporated, such as the stability, e.g., formulation stability, spreadability or staying power of the composition.

[0247] The at least one non-perfume chemical carrier may be a compound, a mixture of compounds or other additive that exhibits no sensory properties or no significant sensory properties. The non-perfume chemical carrier may be used to dilute and / or fix the perfume chemical (I) containing one or more acetate or propionate groups, the acetic acid, and optionally perfume chemicals different from the at least one perfume chemical defined above or other ingredients when included in the composition.

[0248] A further embodiment of the present invention relates to a composition comprising at least one perfume chemical (I) containing one or more acetate or propionate groups as defined above, acetic acid in the concentrations described, and at least one non-perfume chemical carrier selected from the group consisting of solvents, surfactants, and oil components.

[0251] In the context of the present invention, a "solvent" is one that serves to dilute the perfume chemical (I) used according to the invention and / or any further ingredients of the composition that do not themselves have a fragrance.

[0252] The one or more solvents may be present in the composition in an amount of 0.01 to 99% by weight, based on the total weight of the composition. In a preferred embodiment of the present invention, the composition contains 0.1 to 90% by weight, preferably 0.5 to 80% by weight, of the solvent, based on the total weight of the composition. The amount of solvent can be selected depending on the composition. In one embodiment of the present invention, the composition contains 0.05 to 10% by weight, preferably 0.1 to 5% by weight, more preferably 0.2 to 3% by weight, based on the total weight of the composition. In one embodiment of the present invention, the composition contains 20 to 70% by weight, preferably 25 to 50% by weight, of the solvent, based on the total weight of the composition.

[0253] Preferred solvents are ethanol, isopropanol, dipropylene glycol (DPG), propylene glycol, 1,2-butylene glycol, glycerol, diethylene glycol monoethyl ether, diethyl phthalate (DEP), isopropyl myristate (IPM), triethyl citrate (TEC), and benzyl benzoate (BB).

[0257] Most typically, the solvent is ethanol or triethyl citrate.

[0258] According to a further embodiment, at least one perfume chemical (i) in combination with a given amount of acetic acid is used in surfactant-containing compositions according to the present invention.Due to its characteristic fragrance properties and its persistence, longevity and stability, the combination of at least one perfume chemical (I) with the stated amount of acetic acid can be used to impart an odor, preferably a fragrance, impression to surfactant-containing compositions, such as cleaning agents (especially laundry care products and all-purpose cleaners).This can preferably be used to impart a long-lasting clean note to surfactant-containing compositions.

[0259] Thus, one embodiment of the present invention relates to a composition comprising at least one perfume chemical (I) containing one or more acetate or propionate groups as defined above, acetic acid in the concentrations described, and at least one surfactant.

[0260] The surfactants may be selected from anionic, nonionic, cationic and / or amphoteric or zwitterionic surfactants. Surfactant-containing compositions, such as shower gels, foam baths, shampoos, etc., preferably contain at least one anionic surfactant.

[0261] The compositions according to the present invention typically contain surfactants in an amount of 0 to 40% by weight, preferably 0 to 20% by weight, more preferably 0.1 to 15% by weight, and especially 0.1 to 10% by weight, based on the total weight of the composition. Typical examples of nonionic surfactants include fatty alcohol polyglycol ethers, alkylphenol polyglycol ethers, fatty acid polyglycol esters, fatty acid amide polyglycol ethers, fatty amine polyglycol ethers, alkoxylated triglycerides, mixed ethers and mixed formals, optionally partially oxidized alkyl(enyl) oligoglycosides or glucuronic acid derivatives, fatty acid N-alkylglucamides, protein hydrolysates (especially wheat-based vegetable products), polyol fatty acid esters, sugar esters, sorbitan esters, polysorbates, and amine oxides. When nonionic surfactants contain polyglycol ether chains, they can have a conventional homolog distribution, but preferably have a narrow homolog distribution.

[0262] The amphoteric surfactant has at least one quaternary ammonium group and at least one COO group in the molecule. (-) or SO3 (-)These surfactants are surface-active compounds containing a hydroxypropyl group. Particularly suitable zwitterionic surfactants are so-called betaines, such as N-alkyl-N,N-dimethylammonium glycinates, e.g., cocoalkyldimethylammonium glycinate, N-acylaminopropyl-N,N-dimethylammonium glycinates, e.g., cocoacylaminopropyldimethylammonium glycinate, as well as 2-alkyl-3-carboxymethyl-3-hydroxyethylimidazolines and cocoacylaminoethylhydroxyethylcarboxymethylglycinates, which contain 8 to 18 carbon atoms in the alkyl or acyl group. Fatty acid amide derivatives of cocamidopropyl betaine, known under the name CTFA, are particularly preferred.

[0263] Amphoteric surfactants are particularly suitable as cosurfactants. Amphoteric surfactants include C8 to C 18 In addition to the alkyl or acyl group, these surfactants contain at least one free amino group and at least one -COOH or SOH group in the molecule, and are capable of forming an intramolecular salt. Examples of suitable amphoteric surfactants include N-alkylglycines, N-alkylpropionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropylglycines, N-alkyltaurines, N-alkylsarcosines, 2-alkylaminopropionic acids, and alkylaminoacetic acids, all of which contain about 8 to 18 carbon atoms in the alkyl group. Particularly preferred amphoteric surfactants are N-cocoa alkylaminopropionates, cocoacylaminoethylaminopropionates, and acylsarcosines.

[0264] Anionic surfactants are characterized by anionic groups, such as carboxylate, sulfate, sulfonate or phosphate groups, which make them solubilize in water, and lipophilic groups.Dermatologically safe anionic surfactants are known to many practitioners from relevant textbooks and are commercially available.These include, in particular, alkyl sulfates in the form of their alkali metal, ammonium salt or alkanolammonium salts, alkyl ether sulfates, alkyl ether carboxylates, acyl isethionates, acyl sarcosinates, linear C 12 ~C 18 Acyl taurates and sulfosuccinates and acyl glutamates containing alkyl or acyl groups.

[0265] Particularly suitable cationic surfactants are quaternary ammonium compounds, preferably ammonium halides, more specifically chlorides and bromides such as alkyltrimethylammonium chloride, dialkyldimethylammonium chloride, and trialkylmethylammonium chloride, such as cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, lauryldimethylammonium chloride, lauryldimethylbenzylammonium chloride, and tricetylmethylammonium chloride. Additionally, readily biodegradable quaternary ester compounds, such as dialkylammonium methosulfate and methylhydroxyalkyldialkyloxyalkylammonium methosulfate, commercially available under the name Stepantexe, and corresponding products in the Dehyquart® series, can be used as cationic surfactants. "Esterquats" are generally understood to be quaternized fatty acid triethanolamine ester salts. These can impart a particular flexibility to compositions. These are known substances prepared by related methods of organic chemistry. Another cationic surfactant suitable for use in the present invention is quaternized protein hydrolysates.

[0266] One embodiment of the present invention relates to a composition comprising at least one perfume chemical (I) containing one or more acetate or propionate groups as defined above, acetic acid in the concentrations described, and at least one oil component.

[0274] Deodorizing agent One embodiment of the present invention relates to a composition comprising at least one perfume chemical (I) containing one or more acetate or propionate groups as defined above, acetic acid in the concentrations described, and at least one deodorant active.

[0275] At least one perfume chemical (I) containing one or more acetate or propionate groups as defined above, along with the recited amounts of acetic acid, may be used to impart a clean, long-lasting fragrance to deodorant compositions and skin treated with such compositions.

[0276] Deodorizing compositions (deodorants and antiperspirants) neutralize, mask or eliminate body odor, which is caused by the action of skin bacteria on apocrine sweat, resulting in the formation of unpleasant-smelling decomposition products.

[0281] When sweat is present in the underarm area, bacteria form extracellular enzymes, mainly proteases and / or lipases, which decompose the esters present in sweat, releasing odors 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.Esterase inhibitors inhibit enzyme activity, thereby reducing odor generation.The cleavage of citrate esters likely releases free acids, lowering the pH value of the skin to the extent that enzymes are inactivated by acylation. Other esterase inhibitors are, for example, sterol sulfates or phosphates such as lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and their esters, for example glutaric acid, glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid, adipic acid monoethyl ester, adipic acid diethyl ester, malonic acid and malonic acid diethyl ester, hydroxycarboxylic acids and their esters, for example citric acid, malic acid, tartaric acid or tartaric acid diethyl ester and zinc glycine.

[0306] Suitable surfactants of component (a) correspond to those listed above. They can be nonionic, anionic, cationic, zwitterionic or amphoteric. Generally, mixtures of two or more surfactants are used.

[0307] Suitable solvents of component (c) include, for example, C2-C3 alkanols (e.g., ethanol, n-propanol, isopropanol), C2-C3 alkanediols (e.g., ethylene glycol, propylene glycol), C1-C4 alkyl monoethers of C2-C3 alkanediols (e.g., ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, ethylene glycol mono-n-butyl ether (also called butylglycol), propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monopropyl ether, propylene glycol mono-n-butyl ether), polyether polyols (e.g., polyethylene glycol, polypropylene glycol), C1-C3 alkyl monoethers of polyether polyols (e.g., polyethylene glycol monomethyl ether, polyethylene glycol monoethyl ether, polyethylene glycol mono-n-propyl ether, polyethylene glycol mono-n-butyl ether), one or more C1-C 12 5-, 6-, or 7-membered lactones (e.g., γ-butyrolactone, γ-valerolactone, γ-octalactone, γ-nonalactone, δ-valerolactone, δ-decanolactone, δ-dodecanolactone, and ε-caprolactone), which may be substituted with alkyl groups, one or more C1-C 12 5-, 6-, or 7-membered cyclic carbonates (e.g., one or more C1-C 12 Examples of suitable carboxylic acids include ethylene carbonate, propylene carbonate, butylene carbonate, etc., which may have alkyl substituents; aliphatic esters (e.g., ethyl acetate, propyl acetate, butyl acetate, methyl propionate, ethyl propionate); carboxamides (e.g., N,N-dimethylformamide, N,N-diethylformamide, N,N-dimethylacetamide), or mixtures thereof.

[0308] Suitable enzymes of component (d) include hydrolases commonly used in laundry, dishwashing, or surface cleaning compositions, such as proteases, esterases, glucosidases, lipases, deoxyribonucleases, amylases, cellulases, mannanases, other glycosyl hydrolases, and mixtures of the aforementioned enzymes. All of these hydrolases contribute to the dissolution and removal of soils from stains / residues containing protein, grease, or starch. Oxidoreductases can also be used to effect bleaching.

[0309] Component (e), the sequestering agent, also known as a builder, structural material, framework material, complexing agent, chelator, chelating agent, or softener, binds alkaline earth metal and other water-soluble metal salts without precipitating them. They promote soil decomposition, disperse soil components, promote soil release, and may also have cleaning properties themselves. Many sequestering agents are multifunctional, i.e., they have additional functions such as dispersing or anti-darkening properties. Suitable sequestering agents can be either organic or inorganic. Examples include aluminosilicates, carbonates, phosphates and polyphosphates, polycarboxylic acids, polycarboxylates, hydroxycarboxylic acids, phosphonic acids, e.g., hydroxyalkylphosphonic acids, phosphonates, aminopolycarboxylic acids and their salts, and polymeric compounds containing carboxylic acid groups and their salts. More specific examples of inorganic sequestering agents include crystalline or amorphous aluminosilicates, disilicates or layered silicates having ion exchange properties such as zeolites, carbonates and hydrogencarbonates, usually in the form of alkali metal, alkaline earth metal or ammonium salts thereof, alkali metal orthophosphates and / or polyphosphates, such as pentasodium triphosphate. More specific examples of organic sequestering agents include C4 to C6 30 - di-, tri- and tetracarboxylic acids, such as succinic acid, propanetricarboxylic acid, butanetetracarboxylic acid, cyclopentanetetracarboxylic acid and C2-C6 20Alkyl- and alkenyl succinic acids having alkyl or alkenyl groups, hydroxycarboxylic acids and polyhydroxycarboxylic acids (sugar acids), such as malic acid, tartaric acid, glutonic acid, mucic acid, lactic acid, glutaric acid, citric acid, tartronic acid, glucoheptonic acid, lactobionic acid, and sucrose mono-, di-, and tricarboxylic acids, phosphonic acids, such as hydroxyalkylphosphonic acids or aminophosphonic acids and their salts, polyaspartic acid and its salts, polymeric compounds containing carboxylic acid groups such as acrylic acid homopolymers, and maleic acid oligomers.

[0310] The component (f), the antifoaming agent and / or foam stabilizer, is, for example, soap, paraffin, and silicone oil.

[0311] The pH adjuster of component (g) is an acid, a base, or a buffer system. The acid can be inorganic or organic. Suitable inorganic acids include sulfuric acid, hydrochloric acid, and phosphoric acid. Suitable organic acids include saturated, unsubstituted aliphatic C1-C6 mono-, di-, and tricarboxylic acids, such as formic acid, acetic acid, propanoic acid, oxalic acid, succinic acid, and glutaric acid; saturated aliphatic C1-C6 mono-, di-, and tricarboxylic acids having one or more OH groups, such as lactic acid, tartaric acid, and citric acid; unsaturated aliphatic 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. While the organic acid primarily serves to adjust the pH of the composition, some organic acids, such as di- and tricarboxylic acids, can also function as sequestering agents. Suitable bases are especially inorganic bases, such as the carbonates mentioned in connection with the sequestering agent, e.g., sodium or potassium carbonate, as well as alkali metal and alkaline earth metal hydroxides, e.g., NaOH or KOH. Suitable buffers are typical systems, such as hydrogen phosphate / dihydrogen phosphate buffers, carbonate / bicarbonate buffers, acetic acid / acetate, or Tris buffers. Furthermore, most of the acids mentioned above, which are weak acids and whose anionic salts are not strong, also have buffering capacity.

[0312] Examples of further additives (h) are antimicrobial agents, including preservatives, fragrances different from (b), hydrotropes, enzyme stabilizers, bleaches, corrosion inhibitors, dyes, thickeners, activity enhancers and inorganic salts.

[0313] When the composition is liquid or gel-like, it is generally essential that it contain water in an amount of 10 to 99.89% by weight, based on the total weight of the composition. In liquid, ready-to-use compositions (ready-to-use compositions are those that are used immediately and do not require further dilution or addition of additional substances), the amount of water generally ranges from 30 to 99.89% by weight, often from 40 to 99% by weight, based on the total weight of the composition.

[0314] In certain embodiments, the home care composition is a refill concentrate. A refill concentrate contains all of the ingredients of the final, ready-to-use product, but is either essentially free of water ("essentially" contemplates that some ingredients may contain some residual water) or contains much less water than the final, ready-to-use product. The end user simply fills the refill concentrate into a suitable container and adds the indicated amount of water.

[0315] Such refill concentrates preferably comprise: (a) 1 to 60% by weight of one or more surfactants based on the total weight of the composition; (b.1) 0.01 to 5 wt. % of one or more perfume chemicals (I) containing one or more acetate or propionate groups as defined above; (b.2) 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, for example 80 to 150, or 100 to 500, or 150 to 400, or 200 to 300 ppm, based on the total weight of acetic acid and the fragrance chemicals (I) of component (b.1); (c) at least one organic solvent in an amount of 0 to 30% by weight based on the total weight of the composition; (d) at least one enzyme in an amount of 0 to 10% by weight based on the total weight of the composition; (e) at least one sequestering agent in an amount of 0 to 10% by weight, based on the total weight of the composition; (f) at least one antifoaming agent and / or foam stabilizer in an amount of 0 to 10% by weight based on the total weight of the composition; (g) optionally, a pH adjuster in an amount adapted to obtain the desired pH; (h) 0 to 50% by weight of further additives, based on the total weight of the composition; and (i) 0 to 20% by weight of water based on the total weight of the composition (wherein the total of components (a) to (i) is 100% by weight) Includes:

[0316] In another preferred embodiment, the composition of the present invention is a personal care composition. The personal care composition is such that it can be used for hygiene or cosmetic purposes. Examples of suitable personal care compositions are as set forth above.

[0317] Suitable personal care compositions can be in a variety of forms, including liquid formulations such as W / O, O / W, O / W / O, W / O / W, or PIT emulsions and all types of microemulsions; unemulsified aqueous liquids; gels; oils; creams; emulsions; or lotions; sprays (propellant- or pump-action sprays) or aerosols; foams; pastes; or wet wipes (e.g., for cleaning diaper-contact areas). Personal care compositions can be, for example, creams, gels, lotions, alcoholic and aqueous / alcoholic solutions, emulsions, wax / fat compositions, or ointments. Typical ingredients present in such personal care compositions and their amounts vary depending on the specific formulation. Examples of such ingredients are solvents, surfactants, emulsifiers, rheology modifiers (generally thickeners), conditioners, emollients, skin care ingredients, lubricants, fillers, antioxidants, dermatological active ingredients, fragrances, and water.

[0318] Formulations intended primarily for cleansing, such as soaps, shower gels and shampoos, comprise at least one surfactant, often an anionic surfactant, optionally combined with a zwitterionic surfactant, and water. In addition, they generally contain at least one of the following ingredients: emulsifiers, sequestrants, fragrances, pH adjusters (generally organic acids and / or inorganic bases), inorganic salts (often NaCl), dyes, pigments, preservatives, pearlescent agents, opacifiers, viscosity modifiers, conditioning agents, natural hair nutrients, dermatological active ingredients.

[0319] Of particular interest are hair-washing preparations in the form of shampoos, and of particular importance are shower gels, both of which generally comprise water and at least one anionic surfactant.

[0320] Suitable anionic surfactants are virtually all of those described above that are cosmetically acceptable. The total amount of anionic surfactant in shampoo and shower gel compositions is generally in the range of 0.5 to 45% by weight, for example 1.5 to 35% by weight, preferably 2 to 20% by weight, based on the total weight of the composition. In shampoos and shower gels, it is advantageous to use surfactants that are good foaming agents. The shampoo or shower gel composition may further comprise a nonionic, amphoteric, and / or cationic co-surfactant that helps impart aesthetic, tactile, combing, physical, or cleansing properties to the composition. Suitable nonionic, amphoteric / zwitterionic, and cationic surfactants are as described above. The total amount of nonionic surfactants in a shampoo or shower gel composition is generally in the range of 0.5 to 15% by weight, preferably 2 to 10% by weight, based on the total weight of the composition; the total amount of amphoteric or zwitterionic surfactants in a shampoo or shower gel composition is generally in the range of 0.5 to 15% by weight, preferably 1 to 10% by weight; and the total amount of cationic surfactants in a shampoo or shower gel composition is generally in the range of 0.05 to 1% by weight, more preferably 0.08 to 0.5% by weight. The total amount of surfactants (including any co-surfactants and / or any emulsifiers) in a shampoo or shower gel composition is generally in the range of 1 to 50% by weight, preferably 2 to 40% by weight, more preferably 10 to 25% by weight, based on the total weight of the composition.

[0321] In shampoo or shower gel compositions, the at least one perfume chemical (I) containing one or more acetate or propionate groups as defined above is generally present in an amount of from 0.01 to 5 wt. %, preferably from 0.01 to 2 wt. %, in particular from 0.01 to 1 wt. %, based on the total weight of the composition.

[0322] When the shampoo or shower gel composition is in liquid or gel form, it generally contains water in an amount of from 30 to 98% by weight, preferably from 50 to 90% by weight, relative to the total weight of the composition.

[0323] Other ingredients which may be present in shampoos or shower gels are, for example, suspending agents, such as polyacrylic acid, crosslinked polymers of acrylic acid, copolymers of acrylic acid and hydrophobic monomers, copolymers of carboxylic acid-containing monomers and acrylic acid esters, crosslinked copolymers of acrylic acid and acrylate esters, 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), fragrances different from 1,4-butanediol mono- and diacetate, dyes and pigments, pH adjusters, preservatives, pearlizing or opacifying agents, viscosity modifiers and salts such as NaCl; in shampoos, conditioning agents, natural hair nutrients or dermatological active ingredients, such as botanicals, fruit extracts, caffeine, panthenol, sugar derivatives, hydrolyzed keratin or amino acids such as glycine, vegetable oils or hydrogenated vegetable oils may also be present.

[0324] Perfume chemical (I) containing one or more acetate or propionate groups and acetic acid may be processed into the composition by simply mixing directly with a base composition that does not contain only these compounds. Alternatively, perfume chemical (I) containing one or more acetate or propionate groups and acetic acid may be mixed simultaneously or sequentially with other ingredients of the composition or a preformed mixture of some of the other ingredients.

[0325] The perfume chemical (I) containing one or more acetate or propionate groups and acetic acid may at an earlier stage be entrapped in encapsulating materials such as polymers, capsules, microcapsules and nanocapsules, liposomes, film-forming agents, adsorbents such as carbon or zeolites, cyclic oligosaccharides and mixtures thereof, or may be chemically bound to a substrate adapted to release compound (I) upon application of an external stimulus such as light, enzymes, etc., which then allows compound (I) to be mixed with the composition.

[0326] The compositions comprising perfume chemicals (I) containing one or more acetate or propionate groups and acetic acid or these compounds according to the present invention can also be in microencapsulated, spray-dried, in the form of an inclusion complex or in the form of an extrudate. Their properties can be further optimized by so-called "coating" with a material suitable for more targeted release of the scent; for this purpose, waxy synthetic substances such as, for example, polyvinyl alcohol are preferably used.

[0327] Microencapsulation can be carried out, for example, by the so-called coacervation method, using capsule materials such as polyurethane-like substances or soft gelatin. Spray-dried perfume oils can be produced, for example, by spray-drying an emulsion or dispersion containing perfume chemicals (I) containing one or more acetate or propionate groups and acetic acid or the inventive compositions described herein; carrier materials 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, for example, water. Extruded products can be produced by melting perfume chemicals (I) containing one or more acetate or propionate groups or the inventive compositions described herein with a suitable wax-like substance, extruding, and optionally solidifying in a suitable solvent, for example, isopropanol.

[0328] Generally, the total amount of one or more perfume chemicals containing one or more acetate or propionate groups in the composition according to the invention is typically adapted to the specific intended use or intended application and can therefore vary within wide limits. As a rule, standard commercial amounts customarily used in fragrances are used.

[0329] The composition according to the invention may comprise perfume chemicals (I) containing one or more acetate or propionate groups in a total amount of 0.001 to 99.9 wt.-%, preferably 0.01 to 90 wt.-%, more preferably 0.01 to 80 wt.-%, in particular 0.01 to 60 wt.-%, more particularly 0.01 to 40 wt.-%, for example 0.01 to 10 wt.-%, or 0.01 to 15 wt.-%, or 0.01 to 5 wt.-%, or 0.05 to 5 wt.-%, based on the total weight of the composition.

[0330] In one embodiment of the present invention, the composition comprises perfume chemicals (I) containing one or more acetate or propionate groups in a total amount of 0.001 to 10 wt. % or 0.001 to 5 wt. %, preferably 0.01 to 2 wt. % or 0.05 to 5 wt. %, based on the total weight of the composition.

[0331] The present invention relates to a method for preparing a perfume chemical composition, in particular a perfumed composition, in particular a perfumed ready-to-use composition, comprising incorporating into said composition at least one perfume chemical (I) containing one or more acetate or propionate groups as defined above, and acetic acid in an amount such that the acetic acid 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, or 100 to 500, or 150 to 400, or 200 to 300 ppm, based on the total weight of acetic acid and said perfume chemicals; further relates to a process comprising mixing simultaneously or sequentially at least one perfume chemical (I) containing one or more acetate or propionate groups as defined above and acetic acid in an amount such that the acetic acid is present in the resulting composition in an amount of 50-600 ppm, preferably 70-600 ppm, more preferably 70-550 ppm, even more preferably 80-500 ppm, for example 80-150, or 100-500, or 150-400, or 200-300 ppm, based on the total weight of acetic acid and said perfume chemicals, with the other ingredients of said composition or a preformed mixture of some of the other ingredients of said composition.

[0332] The present invention relates to a method for imparting a scent, preferably a fragrance, to a composition, comprising incorporating into said composition at least one perfume chemical (I) containing one or more acetate or propionate groups as defined above, and acetic acid in an amount such that the acetic acid 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, or 100 to 500, or 150 to 400, or 200 to 300 ppm, based on the total weight of acetic acid and said perfume chemicals, or and acetic acid in an amount such that the acetic acid is present in the resulting composition in an amount of from 50 to 600 ppm, preferably from 70 to 600 ppm, more preferably from 70 to 550 ppm, even more preferably from 80 to 500 ppm, for example from 80 to 150, or from 100 to 500, or from 150 to 400, or from 200 to 300 ppm, based on the total weight of acetic acid and said perfume chemicals, simultaneously or sequentially with the other ingredients of the composition or a preformed mixture of some of the other ingredients of the composition.

[0333] The stated concentrations / amounts of acetic acid enhance the scent, especially the aromatic notes, of fragrance chemicals (I) containing one or more acetate or propionate groups. In some cases, acetic acid also modifies the scent notes, especially the aromatic notes, resulting in a fresher, greener scent. Acetic acid is an abundantly available bulk chemical that can be obtained from renewable resources, making it very economical and environmentally and toxicologically harmless.

[0334] The present invention is further illustrated by the following examples. [Example]

[0335] Abbreviation: HOAc acetic acid

[0336] Fragrance chemicals tested: The following fragrance chemicals (i) were tested: - 1,4-butanediol diacetate - Neopentyl glycol diacetate - Isopentyl acetate - Linalyl acetate - Benzyl acetate - Citronellyl Acetate - α-Terpinyl acetate - Hexyl acetate - 2-phenylethyl acetate

[0337] 1,4-butanediol diacetate and neopentyl glycol diacetate were prepared by esterifying the respective glycols with acetic anhydride as described below. Other fragrance chemicals (I) were purchased from Sigma Aldrich.

[0338] Preparation of 1,4-butanediol diacetate Acetic anhydride (1277 g, 12.5 mol, 2.05 equiv.) was added to a 2.5 L jacketed tank equipped with a reflux condenser and impeller stirrer and heated to 120 °C. 1,4-butanediol (550 g, 6.10 mol, 1.00 equiv.) was added within 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 most of the unreacted acetic anhydride and acetic acid, yielding the title product with an acetic acid content of 48 ppm based on the total weight of 1,4-butanediol diacetate and acetic acid (acetic acid content was determined by measuring the acid number by potentiometric titration as described below).

[0339] Preparation of neopentyl glycol diacetate Neopentyl glycol diacetate was prepared similarly to 1,4-butanediol diacetate.

[0340] Preparation of test samples Before preparing the mixture with acetic acid, the commercial product (I) was subjected to a purification step (generally washing with water) to avoid impurities interfering with the perception of the scent. Mixtures of fragrance chemical (I) with acetic acid in a total amount of 50 ppm, 100 ppm, 200 ppm or 500 ppm based on the total weight of acetic acid and the fragrance chemical (I) were prepared. For this purpose, the amount of acetic acid in the fragrance chemical (I) was determined, and then acetic acid was added to the specified concentration.

[0341] The amount of acetic acid was determined by measuring the acid value, which was then measured by potentiometric titration. Samples were dissolved in isopropanol and titrated with a standardized solution of tetrabutylammonium hydroxide (TBAH) in toluene / methanol (0.1 mol / L).

[0342] Olfactory evaluation 10% by weight solutions of fragrance chemical / acetic acid mixtures in triethyl citrate (TEC) were prepared and evaluated by trained perfumers from the headspace of sample vials and from blotter papers (=scent strips). The evaluation of each sample set was carried out under blind conditions, i.e., the perfumers were unaware of the composition of the samples. Intensity was ranked within each series from lowest (=1) to highest (=4) intensity.

[0343] The results are summarized in the table below.

[0344] [Table 1]

[0345] Acetic acid was not detectable on scent strips at any of the above concentrations. Only a weak vinegar odor was detected in the headspace of the sample vial containing 500 ppm acetic acid (no acetic acid / vinegar odor was detected in the case of hexyl acetate).

[0346] As the acetic acid concentration increased, the 1,4-butanediol diacetate / acetic acid sample was perceived as greener and more natural.

[0347] Commercial products and advantageous fragrance compositions "Solution A" is undiluted 1,4-butanediol diacetate containing 100 ppm acetic acid based on the total weight of 1,4-butanediol diacetate and acetic acid (Example 1.1.2).

[0371] II. Advantageous Fragrance Compositions II.1 Perfume formulations for various uses A base formulation was prepared having the composition shown in the table below: DPG is dipropylene glycol.

[0372] [Table 4]

[0373] To this base formulation 2.5% by weight of the product of Example 1.1.2 is added. The resulting perfume formulations are subjected to an olfactory evaluation by a panel of trained perfumers.

[0374] The product of Example 1.1.2 adds a unique impression and signature to the base formulation, imparting red fruit notes to the perfume formulation, making it more pleasant, stronger, more natural, powerful and greener.

[0375] II.2 Perfume formulations for various uses A base formulation was prepared having the composition shown in the table below: DPG is dipropylene glycol.

[0376] [Table 5]

[0377] This base formulation had a green, light fruity, slightly sweet tropical fruit-like aroma, floral notes of jasmine and rose, and a woody, musky back note.

[0378] To this base formulation is added 100 parts by weight of the product of Example 1.1.2. The resulting perfume formulation is characterized by a panel of trained perfumers as being fruitier, sweeter, more raspberry, and with a more pronounced musk note. Thus, the product of Example 1.1.2 also acts as an enhancer for the musk note.

[0379] II.3 Perfume formulations intended for use in dishwashing formulations A base formulation was prepared for use in a dishwashing formulation having the composition shown in the table below.

[0380] [Table 6]

[0381] To this base formulation are added 500 parts by weight of the product of Example 1.1.2. The resulting perfume formulations are subjected to an olfactory evaluation by a panel of trained perfumers.

[0382] The product of Example 1.1.2 adds sweet notes of red fruit and strawberry to the base formulation.

[0383] II.4 Perfume formulations intended for use in reed diffusers A formulation for use in a reed diffuser (a scent dispenser that dispenses scent held in reeds by slow evaporation) is prepared having the composition set forth in the table below.

[0384] [Table 7]

[0385] The resulting perfume formulation is olfactorily assessed by a panel of trained perfumers as being sweeter and fruitier than a formulation without the product of Example 1.1.2.

[0386] II.5 Perfume formulations intended for use in shower gels A basic formulation is prepared for use in a shower gel having the composition shown in the table below.

[0387] [Table 8]

[0388] The resulting perfume formulation has been olfactory evaluated by a panel of trained perfumers as having a floral, musky base layered with a tropical fruit blend including multiple fruit notes such as watermelon, kiwi, pineapple, passion fruit and grapefruit.

[0389] A similar formulation is prepared, differing only in that it contains 50 parts by weight of DPG instead of the product of Example 1.1.2. It is characterized as a clean, fresh tropical fruit blend with prominent notes of watermelon and floral musk.

[0390] Comparing the two blends, the product of Example 1.1.2 appears to have a natural intensifying effect, doubling the various tropical fruit notes, particularly in the direction of pineapple. The watermelon remains, but the other fruits dominate and become more perceptible. The product of Example 1.1.2 therefore also acts as an enhancer of certain notes.

[0391] II.6 Perfume formulations intended for use in shower gels A basic formulation is prepared for use in a shower gel having the composition shown in the table below.

[0392] [Table 9]

[0393] The resulting perfume formulation has been olfactory evaluated by a panel of trained perfumers as having a clean, fresh lavender fragrance with a predominance of natural notes on a modern background provided by woody, musky and citrus elements.

[0394] A similar formulation is prepared, differing only in that it contains 50 parts by weight of DPG instead of the product of Example 1.1.2, and is characterized by a classic lavender fragrance modernized by dihydromyrcenol and Iso E Super, with a fresh citrus top note.

[0395] Comparing the two blends, it is clear that the product of Example 1.1.2 activates the top notes and conveys a stronger sense of naturalness by accentuating the ketonic notes of lavandin and lavender with its fruity notes.

[0396] III. Ready-to-use Compositions III.1 Shampoo or shower gel A shampoo or shower gel formulation is prepared by mixing the following ingredients in the given proportions:

[0397] [Table 10]

[0398] The shower / shampoo formulation has a pleasant fruity fragrance of the scent notes listed in Example II.5.

[0399] A similar formulation containing 1% of the perfume composition of Example II.6 instead of the perfume composition of Example II.5 has a pleasant lavender fragrance with the notes given in Example II.6.

[0400] A similar formulation in which the product of Example 1.1.2 was 0.1% instead of the perfume composition of Example II.5 adequately masked the unpleasant odor of the base formulation (i.e. the above-mentioned shampoo or shower gel without perfume). Formulations in which the product of Example 1.1.2 was 0.1% instead of the perfume composition of Example II.5 have a characteristic fruity odor.

[0401] III.2 Laundry detergent formulations A laundry detergent formulation is prepared by mixing the following ingredients in the given proportions:

[0402] [Table 11]

[0403] The resulting clear, slightly yellowish formulation with a pH of 8.1 has a pleasant fruity fragrance of the perfume notes listed in Example II.1.

[0404] A similar formulation containing 0.5% of the product of Example 1.1.2 instead of the perfume composition of Example II.1 adequately masks the unpleasant odor of the base formulation (i.e. the above laundry detergent without perfume). As the amount of product of Example 1.1.2 increases (however, still below 1%), the characteristic fruity odor becomes stronger.
