BACKGROUND OF THE INVENTION

[0002] Aroma chemicals, especially fragrances, are of great interest especially in the field of cosmetics and cleaning and laundry compositions. Fragrances of natural origin are mostly expensive, often limited in their available amount and, on account of fluctuations in environmental conditions, are also subject to variations in their content, purity etc. To circumvent these undesirable factors, it is therefore of great interest to create synthetic substances which have sensory properties that resemble more expensive natural fragrances or which have novel and interesting sensory profiles.

[0003] Despite a large number of already existing aroma chemicals, there is a constant need for new components in order to be able to satisfy the multitude of properties desired for extremely diverse areas of application. These include, firstly, the sensory properties, i.e. the compounds should have advantageous odiferous (olfactory) or gustatory properties. Furthermore, aroma chemicals should also have additional positive secondary properties, such as e.g. an efficient preparation method, the possibility of providing better sensory profiles as a result of synergistic effects with other aroma chemicals, a higher stability in a wide range of compositions as well as under certain application conditions, a higher extendability and/or a better staying power.

[0004] However, since even small changes in chemical structure bring about massive changes in the sensory properties such as odor and also taste, the targeted search for substances with certain sensory properties such as a certain odor is extremely difficult. The search for new fragrances and flavorings is therefore in most cases difficult and laborious without knowing whether a substance with the desired odor and/or taste will even actually be found.

[0005] Terpenes and terpenoids form a large and heterogeneous group of chemical compounds, whose common feature is that their backbone is based on isoprene units: The "biogenetic isoprene rule" or short "isoprene rule", formulated in the mid 20^th century, predicted that terpenes/terpenoids are biosynthesized via polymerization of C₅ isoprene units. The carbon number in the backbone of terpenes and terpenoids is thus a multiple of 5 (i.e. n × 5 carbon atoms; n being an integer; isoprene rule). Terpenes and terpenoids occur naturally in organisms, often in form of secondary metabolites in plants, animals and microorganisms. Terpenes are pure hydrocarbons of the molecular formula (C₅H₈)_n, whereas terpenoids contain additional functional groups, usually oxygen-containing groups. Terpenes and terpenoids wherein n is 1 are termed hemiterpenes and hemiterpenoids, respectively, terpenes and terpenoids wherein n is 2 are termed monoterpenes and monoterpenoids, respectively, and terpenes and terpenoids wherein n is 3 are termed sesquiterpenes and sesquiterpenoids, respectively. Short-chain terpenes and terpenoids are relevant as aroma compounds, including hemi- (C₅), mono- (C₁₀), and sesquiterpenes and -terpenoids (C₁₅). A known examples for a hemiterpenoid with aroma properties is prenol, which occurs e.g. in hop or ylang-ylang flowers; examples for monoterpenoids and monoterpenes with aroma properties include linalool with a citrus- and lavender-like scent, thymol with a thyme-like flavor, and limonene with a fresh, orange-like odor of the (R)-enantiomer and a pine-like flavor of the (S)-enantiomer; and farnesol and (S)-nerolidol are examples of sesquiterpenoids with aroma properties; they are associated with a flowery scent.

[0006] The biosynthesis of terpenes and terpenoids can however also differ from the sequential condensation of C₅ units, resulting thus in structures with a number of carbon atoms different from a multiple of five. These terpenes/terpenoids are called non-canonical. Non-canonical terpenes or terpenoids are also available via biosynthesis involving the action of methyltransferases, enzymes which catalyze the addition of methyl groups to the prenyl pyrophosphate precursors, thereby changing the final number of carbon atoms of the terpene or terpenoid structures. The methyltransferases sometimes also cyclize the classical isoprenyl diphosphate substrates.

[0007] It was the object of the present invention to provide new aroma chemicals. Besides, these substances should be combinable with other aroma chemicals, allowing the creation of novel advantageous sensory profiles. In addition, the process for the preparation of these new aroma chemicals should be easy and efficient to allow their fast, economic and environmentally friendly manufacturing. A particular object was to provide aroma chemicals with a reduced carbon footprint, especially aroma chemicals which are at least partially available from renewable sources.

[0008] These and further objects are achieved by non-canonical terpenes or terpenoids as defined below.

SUMMARY OF THE INVENTION

[0009] The invention relates to the use of a non-canonical terpene or of a non-canonical terpenoid or of a stereoisomer thereof or of a mixture of different stereoisomers thereof or of a mixture of different non-canonical terpenes and/or non-canonical terpenoids as an aroma chemical.

[0010] The invention relates furthermore to the use of a non-canonical terpene or terpenoid or of a stereoisomer thereof or of a mixture of different stereoisomers thereof or of a mixture of different non-canonical terpenes and/or terpenoids for modifying and/or enhancing the aroma of a composition.

DETAILED DESCRIPTION OF THE INVENTION

Definitions:

[0014] In the context of the present invention, the term "aroma" refers to a sensory property and comprises an odor and/or a flavor.

[0015] The term "aroma chemical" denotes a substance which is used to obtain an aroma impression (the term "aroma impression" is used interchangeably herein with the term "note") and comprises its use to obtain an olfactory and/or a flavor impression. The term "olfactory impression" or "odor impression" denotes an odor impression without any positive or negative judgement, while the term "scent impression" or "fragrance impression" (used interchangeably herein) as used herein is connected to an odor impression which is generally felt as pleasant. Thus, a "fragrance" or "scent" denotes an aroma chemical which predominately induces a pleasant odor impression. A flavor denotes an aroma chemical which induces a taste impression.

[0016] The term "aroma profile" denotes the overall aroma impression of an aroma chemical and is composed of the individual aroma impressions of an aroma chemical.

[0017] The term "aroma composition", as used herein, refers to a composition which induces an aroma. The term aroma composition comprises "odor composition" and/or "flavor composition". An odor composition is a composition which predominately induces an odor impression, whereas a flavor composition is a composition which predominantly induces a taste impression.

[0018] The term "odor composition" comprises "fragrance composition" or "scent composition" (used interchangeably herein), which predominately induce an odor impression which is generally felt as pleasant.

[0019] "Pleasant odor", "pleasant odor impression", "pleasant odiferous properties", "odor impression felt as pleasant" and similar terms are hedonistic expressions which describe the niceness and conciseness of an odor impression conveyed by an aroma chemical. The more general hedonistic expressions "advantageous sensory properties" or "advantageous organoleptic properties" describe the niceness and conciseness of an organoleptic impression conveyed by an aroma chemical. In terms of the present invention, the terms "organoleptic" and "sensory" relate to olfactory or flavor properties. "Niceness" and "conciseness" are terms which are familiar to the person skilled in the art, a perfumer. Niceness generally refers to a spontaneously brought about, positively perceived, pleasant sensory impression. However, "nice" does not have to be synonymous with "sweet". "Nice" can also be the odor of musk or sandalwood. "Conciseness" generally refers to a spontaneously brought about sensory impression which - for the same test panel - brings about a reproducibly identical reminder of something specific. For example, a substance can have an odor which is spontaneously reminiscent of that of an "apple": the odor would then be concisely of "apples". If this apple odor were very pleasant because the odor is reminiscent, for example, of a sweet, fully ripe apple, the odor would be termed "nice". However, the odor of a typical apple tart can also be concise. If both reactions arise upon smelling the substance, in the example thus a nice and concise apple odor, then this substance has particularly advantageous sensory properties.

[0020] The term "odor-intensive substances" refers to substances or aroma chemicals exhibiting intense odor impressions. Intense odor impressions are to be understood as meaning those properties of aroma chemicals which permit a striking perception even in very low gas space concentrations.

[0021] The intensity can be determined via a threshold value determination. A threshold value is the concentration of a substance in the relevant gas space at which an odor impression can just still be perceived by a representative test panel, although it no longer has to be defined. A substance class which probably belongs to the most odor-intensive known substance classes, i.e. has very low odor threshold values, are thiols, whose threshold value is often in the ppb/m³ range.

[0022] The term "tenacity" describes the evaporation behavior over time of an aroma chemical. The tenacity can for example be determined by applying the aroma chemical to a test strip, and by subsequent olfactory evaluation of the odor impression of the test strip. For aroma chemicals with high tenacity the time span after which the panel can still identify an aroma impression is long.

[0023] The term "substantivity" describes the interaction of an aroma chemical with a surface, such as for example the skin or a textile, especially after subsequent treatment of the surface, such as for example washing. The substantivity can for example be determined by washing a textile with a textile detergent composition comprising the aroma chemical and subsequent olfactory evaluation of the textile directly after washing (wet textile) as well as evaluation of the dry textile after prolonged storage.

[0024] The term "stability" describes the behavior of an aroma chemical upon contact with oxygen, light and/or other substances. An aroma chemical with high stability maintains its aroma profile over a long period in time, preferably in a large variety of compositions and under various storage conditions.

[0025] In order to impart a long-lasting aroma impression to a composition or to a surface treated with a composition, the tenacity, the substantivity as well as the stability of the aroma chemical in the compositions should preferably be high.

[0026] The term "booster", "boosting" or "boost" is used herein to describe the effect of enhancing and/or modifying the aroma of an aroma chemical or of a composition. The term "enhancing" comprises an improvement of the niceness and/or conciseness of an aroma and/or an improvement of the intensity. The term "modifying" comprises the change of an aroma profile.

[0027] Booster effects are particularly desired in fragrance composition when top-note-characterized applications are required, in which the odor is to be conveyed particularly quickly and intensively, for example in deodorants, air fresheners or in the taste sector in chewing gums.

[0028] The terms "compound" and "substance" are used synonymously throughout the invention.

[0029] As already explained above, terpenes and terpenoids are a group of chemical compounds whose common feature is that their backbone is based on isoprene units. The carbon number in their backbone is thus a multiple of 5 (i.e. n × 5 carbon atoms; n being an integer; isoprene rule). Terpenes are pure hydrocarbons of the molecular formula (C₅H₈)_n, whereas terpenoids contain additional functional groups, usually oxygen-containing groups, e.g. OH groups, C=O groups or ether groups -O-. Terpenes and terpenoids wherein n is 1 are termed hemiterpenes and hemiterpenoids, respectively; terpenes and terpenoids wherein n is 2 are termed monoterpenes and monoterpenoids, respectively; and terpenes and terpenoids wherein n is 3 are termed sesquiterpenes and sesquiterpenoids, respectively.

[0030] Non-canonical terpenes and non-canonical terpenoids are structurally related to terpenes or terpenoids; due to a different biosynthesis or structural modification, the number of their carbon atoms is however different from a multiple of five.

[0031] "Methylated" in context with the present non-canonical terpenes or terpenoids means that one or more hydrogen atoms bound to a carbon atom of a basic, "classical" terpene or terpenoid structure (i.e. having n × 5 carbon atoms) is/are replaced by a methyl (CH₃) group.

[0032] "Methylenated" in context with the present non-canonical terpenes or terpenoids means that two hydrogen atoms bound to the same carbon atom of the basic, "classical" terpene or terpenoid structure (i.e. having n × 5 carbon atoms) are replaced by a methylene (=CH₂) group.

[0033] If in the following the non-canonical terpene or terpenoid is defined to be a specific, defined compound (and not to be a mixture of different non-canonical terpenes and/or terpenoids), this means that the non-canonical terpene or terpenoid contains less than 0.1 % by weight of another non-canonical terpene or terpenoid, relative to the overall weight of the specific, defined non-canonical terpene or terpenoid and the optionally present other non-canonical terpenes or terpenoids.

[0034] "Mixture of different non-canonical terpenes and/or terpenoids" means a mixture of two or more different non-canonical terpenes or a mixture of two or more different non-canonical terpenoids or a mixture of one or more non-canonical terpenes and one or more non-canonical terpenoids.

[0035] The term "stereoisomers" as used in context with the present invention relates to optical isomers, such as enantiomers or diastereomers, the latter existing due to more than one stereogenic center in the molecule, as well as to (Z/E) isomers (due to the presence of correspondingly substituted double bonds or ring systems).

[0036] Unless stated otherwise, the remarks made below concerning preferred definitions, e.g. of the non-canonical terpenes and terpenoids and other components, apply to the use, methods and compositions of the invention.

E.24. The method according embodiment E.23, for conferring a fragrance to a composition.

[0038] The companies from which the above-listed aroma chemical compounds identified by tradenames and indices can be obtained are listed below.

[0039] Preferably, the non-canonical terpene or terpenoid is a methylated or methylenated terpene or terpenoid. As explained above, in a methylated terpene or terpenoid, one or more hydrogen atoms bound to a carbon atom of the basic, "classical" terpene or terpenoid structure (i.e. having n × 5 carbon atoms) is/are replaced by a methyl (CH₃) group. In a methylenated terpene or terpenoid, two hydrogen atoms bound to the same carbon atom of the basic, "classical" terpene or terpenoid structure are replaced by a methylene (=CH₂) group.

[0040] Preferably, the non-canonical terpene is derived from a hemiterpene (C₅), monoterpene (C₁₀) or sesquiterpene (C₁₅), and the non-canonical terpenoid is derived from a hemiterpenoid (C₅), monoterpenoid (C₁₀) or sesquiterpenoid (C₁₅). The non-canonical hemiterpene or hemiterpenoid contains thus 5+x carbon atoms, x being an integer and generally 1, 2 or 3, most frequently 1 or 2; the non-canonical monoterpene or monoterpenoid contains 10+x carbon atoms, x being an integer and generally 1, 2 or 3, most frequently 1 or 2; and the non-canonical sesquiterpene or sesquiterpenoid contains 15+x carbon atoms, x being an integer and generally 1, 2 or 3, most frequently 1 or 2.

[0041] As explained above, terpenoids differ from terpenes, which are pure hydrocarbons consisting exclusively of C and H atoms, in containing additional functional groups, usually oxygen-containing groups, e.g. OH groups, C=O groups or ether groups -O-. Preferably, the non-canonical terpenoid contains a hydroxyl group as only functional group.

[0042] More preferably, the non-canonical terpene or terpenoid is derived from bornane, camphene, 3-carene, limonene, prenol, isoprenol, α-fenchol, α-terpineol, citronellol, geraniol, nerol, linalool or farnesol and is even more preferably selected from the group consisting of methylated or methylenated bornane, camphene, 3-carene, limonene, prenol, isoprenol, α-fenchol, α-terpineol, citronellol, geraniol, nerol, linalool and farnesol. The basic terpene or terpenoid is preferably methylated or methylenated with 1, 2 or 3, more preferably with 1 or 2 methyl and/or methylene groups.

[0043] Even more preferably, the non-canonical terpene or terpenoid is selected from the group consisting of monomethylenated or monomethylated bornane, monomethylated camphene, monomethylated 3-carene, monomethylated limonene, mono- or dimethylated prenol, mono- or dimethylated isoprenol, monomethylated α-fenchol, monomethylated α-terpineol, monomethylated citronellol, monomethylated geraniol, monomethylated nerol, monomethylated linalool and monomethylated farnesol.

[0050] Generally, an easy-to-cultivate microorganism suitable for biotechnological processes, mostly a bacterium, such as Escherichia coli, or a yeast, such as Saccharomyces cerevisae, is modified by transferring genes encoding prenyl methyltransferases (just by way of example geranyl pyrophosphate transferase from Streptomyces coelicolor or isopentenyl pyrophosphate methyltransferase from Streptomyces monomycini) and optionally also the suitable synthase (just by way of example 2-methylene bornane synthase from Pseudomonas fluorescens for producing 2-methylenebornane). The thusly modified microorganism is used for the production of the desired compound. If the microorganism produces more than one compound, this can be isolated from the obtained mixture by usual means, such as chromatography, or by distillative or extractive methods.

[0051] Preferably, the non-canonical terpenes or terpenoids, the stereoisomers thereof, the mixtures of different stereoisomers and the mixtures of different non-canonical terpenes and/or terpenoids are used as a fragrance.

[0058] Details to the above-listed compositions are given below.

[0059] In addition to the olfactory properties, the non-canonical terpene or terpenoid, the stereoisomer thereof, the mixture of different stereoisomers and the mixture of different non-canonical terpenes and/or terpenoids exhibit advantageous secondary properties.

[0060] For example, they can provide better sensory profiles as a result of synergistic effects with other fragrances, which means that they can provide a booster effect for other fragrances. They are therefore suitable as boosters for other fragrances.

[0061] Accordingly, another aspect of the invention relates to the use of non-canonical terpenes or terpenoids, of stereoisomers thereof, of mixtures of different stereoisomers and of mixtures of different non-canonical terpenes and/or terpenoids for modifying the scent character of a fragranced composition; and specifically to the use as a booster for other fragrances.

[0062] Booster effect means that the substances enhance and intensify in perfumery formulations the overall impression of the mixture. In the mint range, for example, it is known that menthyl methyl ether intensifies the perfumery or taste mixtures of peppermint oils and particularly in top notes brings about a considerably more intensive and more complex perception although the ether itself, being a pure substance, develops no particular intensive odor at all. In fragrance applications, Hedione^® (methyl dihydrojasmonate), which as a pure substance only exhibits a light floral jasmine-note, reinforces diffusion, freshness and volume of a perfume composition as an odor booster. Booster effects are particularly desired when top-note-characterized applications are required, in which the odor impression is to be conveyed particularly quickly and intensively, for example in deodorants, air fresheners or in the taste sector in chewing gums.

[0063] To achieve such a booster effect, the non-canonical terpenes or terpenoids, the stereoisomers thereof, the mixtures of different stereoisomers and the mixtures of different non-canonical terpenes and/or terpenoids are generally used in an overall amount of 0.1 to 20% by weight, preferably in an amount of 0.5 to 5% by weight, in particular in an amount of from 0.6 to 3% by weight, based on the total weight of the fragrance mixture.

[0064] Furthermore, the non-canonical terpene or terpenoid, the stereoisomer thereof, the mixture of different stereoisomers and the mixture of different non-canonical terpenes and/or terpenoids can have further positive effects on the composition in which they are used. For example, they can enhance the overall performance of the composition into which they are incorporated, such as the stability, e.g. the formulation stability, the extendability or the staying power of the composition.

[0065] A further embodiment of the invention is directed to a method of preparing an aroma chemical composition, in particular a fragranced composition, especially a fragranced ready-to-use composition, comprising incorporating at a non-canonical terpene or terpenoid, a stereoisomer thereof, a mixture of different stereoisomers or a mixture of different non-canonical terpenes and/or terpenoids into the target composition, e.g. a ready-to-use composition, resulting in an aroma chemical composition, in particular in a fragranced composition, especially in a fragranced ready-to-use composition. Alternatively, the invention is directed to a method of preparing an aroma chemical composition, in particular a fragranced composition, especially a fragranced ready-to-use composition, comprising mixing the non-canonical terpene or terpenoid, the stereoisomer thereof, the mixture of different stereoisomers or the mixture of different non-canonical terpenes and/or terpenoids with at least one aroma chemical different therefrom and/or with at least one non-aroma chemical carrier and/or with at least one antioxidant and/or with at least one deodorant-active agent. Suitable and preferred aroma chemicals different from said non-canonical terpenes and terpenoids, non-aroma chemical carriers, antioxidants and deodorant-active agents are described below.

[0066] For example, the method can be carried out by mixing the non-canonical terpene or terpenoid, the stereoisomer thereof, the mixture of different stereoisomers or the mixture of different non-canonical terpenes and/or terpenoids, as defined above, and at least one further component selected from the group consisting of aroma chemicals different therefrom, non-aroma chemical carriers, antioxidants and deodorant-active agents.

Non-aroma chemical carriers

[0122] A further embodiment of the invention is directed to a composition comprising a non-canonical terpene or terpenoid or a stereoisomer thereof or a mixture of different stereoisomers thereof or a mixture of different non-canonical terpenes and/or terpenoids, and at least one non-aroma chemical carrier.

[0123] The at least one non-aroma chemical carrier can be a compound, a mixture of compounds or other additives which has/have no or no noteworthy sensory properties. The non-aroma chemical carrier can serve for the dilution and/or the fixing of the non-canonical terpene or terpenoid and the optionally present at least one aroma chemical, as defined above, or any other component, if comprised in the composition.

[0124] A further embodiment of the invention is directed to a composition comprising a non-canonical terpene or terpenoid or a stereoisomer thereof or a mixture of different stereoisomers thereof or a mixture of different non-canonical terpenes and/or terpenoids, and at least one non-aroma chemical carrier selected from the group consisting of solvents, surfactants and oil components.

[0125] According to preferred embodiments of the present invention, said non-aroma chemical carrier(s) is/are selected from the solvents, surfactants and oil components listed below.

[0126] One embodiment of the invention is directed to a composition comprising a non-canonical terpene or terpenoid or a stereoisomer thereof or a mixture of different stereoisomers thereof or a mixture of different non-canonical terpenes and/or terpenoids, as described herein and at least one solvent.

[0127] In the context of the present invention, a "solvent" serves for the dilution of the compound(s) (I) to be used according to the invention and/or any further component of the composition without having its own aroma.

[0128] The one or more solvent(s) can be present in the composition in amount of 0.01 to 99 wt.% based on the composition. In a preferred embodiment of the invention, the composition comprises 0.1 to 90 wt.%, preferably 0.5 to 80 wt.% of solvent(s) based on the total weight of the composition. The amount of solvent(s) can be chosen depending on the composition. In one embodiment of the invention, the composition comprises 0.05 to 10 wt.%, preferably 0.1 to 5 wt.%, more preferably 0.2 to 3 wt.% based on the total weight of the composition. In one embodiment of the invention, the composition comprises 20 to 70 wt.%, preferably 25 to 50 wt.% of solvent(s) based on the total weight of the composition.

[0129] 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).

[0130] Especially preferred solvents are selected from the group consisting of ethanol, propylene glycol, dipropylene glycol, triethyl citrate, benzyl benzoate and isopropyl myristate.

[0131] In a preferred embodiment of the invention, the solvent is selected from the group consisting of 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), benzyl benzoate and mixtures thereof.

[0132] According to a further embodiment, the non-canonical terpene or terpenoid, the stereoisomer thereof, the mixture of different stereoisomers thereof or the mixture of different non-canonical terpenes and/or terpenoids is used according to the present invention in surfactant-containing compositions. Due to its characteristic fragrance property and its substantivity, tenacity as well as stability, the non-canonical terpene or terpenoid, the stereoisomer thereof, the mixture of different stereoisomers thereof or the mixture of different non-canonical terpenes and/or terpenoids can especially be used to provide an odor, preferably a fragrance impression to surfactant-containing compositions such as, for example, cleaners (in particular laundry care products and all-purpose cleaners). It can preferably be used to impart a long-lasting clean note to a surfactant comprising composition.

[0133] One embodiment of the invention is therefore directed to a composition comprising a non-canonical terpene or terpenoid or a stereoisomer thereof or a mixture of different stereoisomers thereof or a mixture of different non-canonical terpenes and/or terpenoids, and at least one surfactant.

[0134] The surfactant(s) may be selected from anionic, non-ionic, cationic and/or amphoteric or zwitterionic surfactants. Surfactant-containing compositions, such as for example shower gels, foam baths, shampoos, etc., preferably contain at least one anionic surfactant.

[0135] The compositions according to the invention usually contain the surfactant(s), in the aggregate, in an amount of 0 to 40 wt.%, preferably 0 to 20 wt.%, more preferably 0.1 to 15 wt.%, and particularly 0.1 to 10 wt.%, based on the total weight of the composition. Typical examples of nonionic surfactants are 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 partly oxidized alk(en)yl oligoglycosides or glucuronic acid derivatives, fatty acid-N-alkyl glucamides, protein hydrolyzates (particularly wheat-based vegetable products), polyol fatty acid esters, sugar esters, sorbitan esters, polysorbates and amine oxides. If the nonionic surfactants contain polyglycol ether chains, they may have a conventional homolog distribution, although they preferably have a narrow-range homolog distribution.

[0136] Zwitterionic surfactants are surface-active compounds which contain at least one quaternary ammonium group and at least one -COO^(-) or -SO₃^(-) group in the molecule. Particularly suitable zwitterionic surfactants are the so-called betaines, such as the N-alkyl-N,N-dimethyl ammonium glycinates, for example, cocoalkyl dimethyl ammonium glycinate, N-acylaminopropyl-N,N-dimethyl ammonium glycinates, for example, cocoacylaminopropyl dimethyl ammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethyl imidazolines, containing 8 to 18 carbon atoms in the alkyl or acyl group, and cocoacylaminoethyl hydroxyethyl carboxymethyl glycinate. The fatty acid amide derivative known under the CTFA name of Cocamidopropyl Betaine is particularly preferred.

[0137] Ampholytic surfactants are also suitable, particularly as co-surfactants. Ampholytic surfactants are surface-active compounds which, in addition to a C₈ to C₁₈ alkyl or acyl group, contain at least one free amino group and at least one -COOH- or -SO₃H- group in the molecule and which are capable of forming inner salts. Examples of suitable ampholytic surfactants are N-alkyl glycines, N-alkyl propionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropyl glycines, N-alkyl taurines, N-alkyl sarcosines, 2-alkylaminopropionic acids and alkylaminoacetic acids containing around 8 to 18 carbon atoms in the alkyl group. Particularly preferred ampholytic surfactants are N-cocoalk-ylaminopropionate, cocoacylaminoethyl aminopropionate and acyl sarcosine.

[0138] Anionic surfactants are characterized by a water-solubilizing anionic group such as, for example, a carboxylate, sulfate, sulfonate or phosphate group and a lipophilic group. Dermatologically safe anionic surfactants are known to the practitioner in large numbers from relevant textbooks and are commercially available. They are, in particular, alkyl sulfates in the form of their alkali metal, ammonium or alkanolammonium salts, alkylether sulfates, alkylether carboxylates, acyl isethionates, acyl sarcosinates, acyl taurines containing linear C₁₂-C₁₈ alkyl or acyl groups and sulfosuccinates and acyl glutamates in the form of their alkali metal or ammonium salts.

[0139] Particularly suitable cationic surfactants are quaternary ammonium compounds, preferably ammonium halides, more especially chlorides and bromides, such as alkyl trimethyl ammonium chlorides, dialkyl dimethyl ammonium chlorides and trialkyl methyl ammonium chlorides, for example, cetyl trimethyl ammonium chloride, stearyl trim ethyl ammonium chloride, distearyl dimethyl ammonium chloride, lauryl dimethyl ammonium chloride, lauryl dimethyl benzyl ammonium chloride and tricetyl methyl ammonium chloride. In addition, the readily biodegradable quaternary ester compounds, such as, for example, the dialkyl ammonium methosulfates and methyl hydroxyalkyl dialkoyloxyalkyl ammonium methosulfates marketed under the name of Stepantexe and the corresponding products of the Dehyquart^® series, may be used as cationic surfactants. "Es-terquats" are generally understood to be quaternized fatty acid triethanolamine ester salts. They can provide the compositions with particular softness. They are known substances which are prepared by the relevant methods of organic chemistry. Other cationic surfactants suitable for use in accordance with the invention are the quaternized protein hydrolyzates.

• amino acids (for example glycine, alanine, arginine, serine, threonine, histidine, tyrosine, tryptophan) and derivatives thereof,
• imidazoles (e.g. urocanic acid) and derivatives thereof,
• peptides, such as D,L-carnosine, D-carnosine, L-carnosine (=β -Alanyl-L-histidin) and derivatives thereof

Deodorant-active agents

[0148] One embodiment of the invention is directed to a composition comprising a non-canonical terpene or terpenoid or a stereoisomer thereof or a mixture of different stereoisomers thereof or a mixture of different non-canonical terpenes and/or terpenoids, and at least one deodorant-active agent.

[0149] The non-canonical terpene or terpenoid, the stereoisomer thereof, the mixture of different stereoisomers thereof or the mixture of different non-canonical terpenes and/or terpenoids can be used to impart a clean, long-lasting note to deodorizing compositions as well as to the skin treated with such compositions.

[0150] Deodorizing compositions (deodorants and antiperspirants) counteract, mask or eliminate body odors. Body odors are formed through the action of skin bacteria on apocrine perspiration which results in the formation of unpleasant-smelling degradation products.

[0151] In a preferred embodiment of the invention, the at least one deodorant-active agent is selected from the groups consisting of anti-perspirants, esterase inhibitors and antibacterial agents.

[0152] Suitable antiperspirants can be selected from the group consisting of salts of aluminium, zirconium or zinc. Examples are aluminium chloride, aluminium chlorohydrate, aluminium dichlorohydrate, aluminium sesquichlorohydrate and complex compounds thereof, for example with 1,2-propylene glycol, aluminium hydroxyallantoinate, aluminium chloride tartrate, aluminium zirconium trichlorohydrate, aluminium zirconium tetrachlorohydrate, aluminium zirconium pentachlorohydrate and complex compounds thereof, for example with amino acids, such as glycine. Aluminium chlorohydrate, aluminium zirconium tetrachlorohydrate, aluminium zirconium pentachlorohydrate and complex compounds thereof are preferably used.

[0153] In a preferred embodiment of the invention the compositions comprise at least one antiperspirant selected from the group consisting aluminium chloride, aluminium chlorohydrate, aluminium dichlorohydrate, aluminium sesquichlorohydrate, aluminium hydroxyallantoinate, aluminium chloride tartrate, aluminium zirconium trichlorohydrate, aluminium zirconium tetrachlorohydrate and aluminium zirconium pentachlorohydrate

[0154] The compositions according to the invention can comprise the antiperspirants in an amount of 1 to 50, preferably 5 to 30 and more particularly 10 to 25 wt.-%, based on the solids content of the composition.

[0155] Where perspiration is present in the underarm region, extracellular enzymes-esterases, mainly proteases and/or lipases are formed by bacteria and split the esters present in the perspiration, releasing odors in the process. Suitable esterase inhibitors are for example trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and, in particular, triethyl citrate. Esterase inhibitors inhibit enzyme activity and thus reduce odor formation. The free acid is probably released by the cleavage of the citric acid ester and reduces the pH value of the skin to such an extent that the enzymes are inactivated by acylation. Other esterase inhibitors are sterol sulfates or phosphates such as, for example, lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and esters thereof, 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 esters thereof, for example citric acid, malic acid, tartaric acid or tartaric acid diethyl ester, and zinc glycinate.

[0156] In a preferred embodiment of the invention the 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, glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid, adipic acid monoethyl ester, adipic acid diethyl ester, malonic acid, malonic acid diethyl ester, citric acid, malic acid, tartaric acid, tartaric acid diethyl ester and zinc glycinate.

[0157] The compositions according to the invention can comprise the esterase inhibitors in amounts of 0.01 to 20, preferably 0.1 to 10 and more particularly 0.5 to 5 wt.-%, based on the solids content of the composition.

[0158] The term "anti-bacterial agents" as used herein encompasses substances which have bactericidal and/or bacteriostatic properties. Typically these substances act against gram-positive bacteria such as, for example, 4-hydroxybenzoic acid and salts and esters thereof, N-(4-chlorophenyl)-N'-(3,4-dichlorophenyl)-urea, 2,4,4'-trichloro-2'-hydroxydiphenylether (triclosan), 4-chloro-3,5-dimethylphenol, 2,2'-methylene-bis-(6-bromo-4-chlorophenol), 3-methyl-4-(1-methylethyl)-phenol, 2-benzyl-4-chlorophenol, 3-(4-chlorophenoxy)-propane-1,2-diol, 3-iodo-2-propinyl butyl carbamate, chlorhexidine, 3,4,4'-trichlorocarbanilide (TTC), phenoxyethanol, glycerol monocaprate, glycerol monocaprylate, glycerol monolaurate (GML), diglycerol monocaprate (DMC), salicylic acid-N-alkylamides such as, for example, salicylic acid-n-octyl amide or salicylic acid-n-decyl amide.

Food supplements may be found in many forms such as tablets, capsules, softgels, gelcaps, liquids, or powders.

[0173] Pharmaceutical compositions comprise compositions which are intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease as well as articles (other than food) intended to affect the structure or any function of the body of man or other animals.

[0174] Crop protection compositions comprise compositions which are intended for the managing of plant diseases, weeds and other pests (both vertebrate and invertebrate) that damage agricultural crops and forestry.

[0175] The compositions according to the invention can further comprise one or more substances, such as, for example: preservatives, abrasives, anti-acne agents, agents to combat skin aging, antibacterial agents, anti-cellulite agents, antidandruff agents, anti-inflammatory agents, irritation-preventing agents, irritation-alleviating agents, antimicrobial agents, antioxidants, astringents, sweat-inhibiting agents, antiseptics, anti-statics, binders, buffers, carrier materials, chelating agents, cell stimulants, cleaning agents, care agents, hair removal agents, surface-active substances, deodorizing agents, antiperspirants, emulsifiers, enzymes, essential oils, fibers, film formers, fixatives, foam formers, foam stabilizers, substances for preventing foaming, foam boosters, fungicides, gelling agents, gel-forming agents, hair care agents, hair shaping agents, hair smoothing agents, moisture-donating agents, moisturizing substances, humectant substances, bleaching agents, strengthening agents, stain removal agents, optical brighteners, impregnating agents, soil repellents, friction-reducing agents, lubricants, moisturizing creams, ointments, opacifiers, plasticizers, covering agents, polish, shine agents, polymers, powders, proteins, refatting agents, exfoliating agents, silicones, skin-calming agents, skin-cleansing agents, skin care agents, skin-healing agents, skin lightening agents, skin-protective agents, skin-softening agents, cooling agents, skin-cooling agents, warming agents, skin-warming agents, stabilizers, UV-absorbent agents, UV filters, fabric softeners, suspending agents, skin-tanning agents, thickeners, vitamins, waxes, fats, phospholipids, saturated fatty acids, mono- or polyunsaturated fatty acids, α-hydroxy acids, polyhydroxy fatty acids, liquefiers, dyes, color-protection agents, pigments, anti-corrosives, polyols, electrolytes, or silicone derivatives.

[0176] The non-canonical terpenes or terpenoids, the stereoisomers thereof, the mixtures of different stereoisomers thereof and the mixtures of different non-canonical terpenes and/or terpenoids may be worked into in compositions simply by directly mixing them with the basic composition lacking only this/these compound(s). Alternatively, the non-canonical terpenes or terpenoids, the stereoisomers thereof, the mixtures of different stereoisomers thereof or the mixtures of different non-canonical terpenes and/or terpenoids may be mixed simultaneously or consecutively with the other components of the composition or with pre-formed mixtures of a part of the other components.

[0177] The non-canonical terpenes or terpenoids, the stereoisomers thereof, the mixtures of different stereoisomers thereof or the mixtures of different non-canonical terpenes and/or terpenoids may, in an earlier step, be entrapped with an entrapment material, for example, polymers, capsules, microcapsules and nanocapsules, liposomes, film formers, absorbents such as carbon or zeolites, cyclic oligosaccharides and mixtures thereof, or may be chemically bonded to substrates, which are adapted to release said non-canonical terpenes or terpenoids upon application of an external stimulus such as light, enzyme, or the like, and then mixed with the composition.

[0178] The non-canonical terpenes or terpenoids, the stereoisomers thereof, the mixtures of different stereoisomers thereof or the mixtures of different non-canonical terpenes and/or terpenoids and compositions comprising these compounds can also be in mi-croencapsulated form, spray-dried form, in the form of inclusion complexes or in the form of extrusion products. The properties can be further optimized by so-called "coating" with suitable materials with regard to a more targeted release of the scent, for which purpose preferably waxy synthetic substances such as e.g. polyvinyl alcohol are used.

[0179] The microencapsulation can take place for example by the so-called coacervation method with the help of capsule materials, e.g. made of polyurethane-like substances or soft gelatin. The spray-dried perfume oils can be produced for example by spray-drying an emulsion or dispersion comprising a non-canonical terpene or terpenoid or a stereoisomer thereof or a mixture of different stereoisomers thereof or a mixture of different non-canonical terpenes and/or terpenoids, or a composition of the present invention described herein, wherein carrier substances that can be used are modified starches, proteins, dextrin and vegetable gums. Inclusion complexes can be prepared e.g. by introducing dispersions of fragrance compositions and cyclodextrins or urea derivatives into a suitable solvent, e.g. water. Extrusion products can be produced by melting a non-canonical terpene or terpenoid or a stereoisomer thereof or a mixture of different stereoisomers thereof or a mixture of different non-canonical terpenes and/or terpenoids, or a composition of the present invention described herein with a suitable wax-like substance and by extrusion with subsequent solidification, optionally in a suitable solvent, e.g. isopropanol.

[0180] Generally, the total amount of the one or more non-canonical terpene or terpenoid in the compositions according to the present invention is typically adapted to the particular intended use or the intended application and can, thus, vary over a wide range. As a rule, the customary standard commercial amounts for scents are used.

[0181] The compositions according to the invention can comprise the non-canonical terpene or terpenoid in an overall amount of from 0.001 to 99.9% by weight, preferably from 0.01 to 90% by weight, more preferably from 0.05 to 80%, in particular from 0.1 to 60% by weight, more particularly from 0.1 to 40% by weight, e.g. from 0.1 to 10% by weight or 0.1 to 15% by weight, based on the total weight of the composition.

[0182] In one embodiment of the invention, the compositions comprise the non-canonical terpene or terpenoid in an overall amount of from 0.001 to 5 weight%, preferably from 0.01 to 2 weight% based on the total weight of the composition.

[0183] The non-canonical terpenes and terpenoids not only have a pleasant aroma, especially fragrance; they are also readily available. In particular they can be readily produced with a reduced CO₂ footprint, e.g. by using renewable sources.

[0184] The following examples serve as further illustration of the invention.
