The present invention primarily relates to fragrance substance mixtures, preferably perfume oils, comprising
and
Furthermore, the present invention relates to perfumed products containing fragrance substance mixtures of this type according to the invention, in particular perfume oils, and a method for modifying certain olfactory properties of fragrance substances, fragrance substance mixtures, perfume oils or correspondingly perfumed products.
Diverse isolongifolenyl alkyl ethers and their olfactory properties are described in EP 1 178 105. EP 1 178 105 also discloses isolongifolenyl methyl ethers, also including the two isomeric compounds (A-1) and (A-2). Ambergris, dry musk, slightly spicy and weakly woody patchouli are given there as the odour evaluation for the stereoisomer (A-1). Stereoisomer (A-2) is characterised there as a fragrance substance with an odour of musk, slightly floral, cashmeran, exalting and spicy. EP 1 178 105 furthermore discloses an odour of strongly musk, powdery, cashmeran, ambergris, exalting and slightly woody for a mixture comprising 37.6 GC-% (A-1) and 59.1 GC-% (A-2).
Mixtures or combinations of these isolongifolenyl alkyl ethers with further musk fragrance substances, which are not isolongifolenyl alkyl ethers, are not disclosed in EP 1 178 105. EP 1 178 105 discloses, in particular, no quantity ratios and no olfactory effects in the combination of these isolongifolenyl alkyl ethers with musk fragrance substances that are structurally different from them.
There is repeatedly a need in perfumery to modify, to emphasise (i.e. intensify or enhance) or to mask (i.e. to reduce or suppress) certain olfactory aspects of a fragrance substance or a fragrance substance mixture.
Perfume oils and perfumed products containing one or more musk fragrance substances are known to the person skilled in the art in the perfumery area, see, for example, EP 1 552 814.
Musk fragrance substances are known to the person skilled in the art and play a very important part in perfumery. The person skilled in the art in the perfumery area knows that in musk fragrance substances, in particular macrocyclic musk fragrance substances, apart from their typical desired main notes, which bring about an erogenous, masculine and animalistic odour, undesired secondary notes can occur. Such undesired and disturbing secondary notes, also called faulty notes or off notes, are metallic notes, in particular notes of hot pressing irons (called pressing iron note below), such as also described for musk fragrance substances in EP 1 487 816 and EP 1 220 850.
A further disadvantageous effect, which can be observed in conjunction with musk fragrance substances in a fragrance substance composition or a perfume oil, is the lowering or reduction of the odour intensity (i.e. the total odour intensity) of a fragrance substance composition of this type or a perfume oil of this type. There is therefore also regularly the necessity to counteract the lowering or reduction of the odour intensity of a fragrance substance composition of this type or a perfume oil of this type by adding odourintensifying substances (so-called “enhancers” or “boosters”).
The primary object of the present invention was to find a substance (substance or substance mixture), capable of modifying, preferably masking, i.e. reducing or suppressing, the undesired olfactory notes of musk fragrance substances, in particular of macrocyclic musk fragrance substances. These undesired notes are, in particular, metallic notes, in particular odour notes of a hot pressing iron.
In addition to the modifying or masking effect, the substance looked for should preferably also be able to counteract the lowering or reduction of the odour intensity (i.e. the total odour intensity) of a fragrance substance composition of this type or a perfume oil of this type regularly observed in conjunction with musk fragrance substances in a fragrance substance composition or a perfume oil. It should therefore preferably be possible in this regard to bring about an olfactory intensification or emphasis (“enhancer” or “booster” effect).
This object is achieved by a fragrance substance mixture according to the invention, preferably by a perfume oil according to the invention, comprising
and
Constituent (a) of a fragrance substance mixture according to the invention is a diastereomeric mixture. Constituent (a) consists of the two epimeric compounds (A-1) and (A-2).
The compounds (A-1) and (A-2) of the structure formulas given above are certain isomers of the isolongifolenyl methyl ether and known per se from the literature. They may, for example, be produced as described in EP 1 178 105 (see above).
The mass ratio of the total quantity of the isomer (A-1) to the total quantity of the isomer (A-2) is preferably greater than or equal to 11:4, preferably greater than or equal to 3:1, more preferably greater than or equal to 7:2.
The mass ratio of the total quantity of the isomer (A-1) to the total quantity of the isomer (A-2) is preferably in the range from 3:1 to 12:1, more preferably in the range from 7:2 to 10:1, particularly preferably in the range from 15:4 to 10:1, and most preferably in the range from 4:1 to 8:1.
The isomeric mixtures to be used according to the invention of the compounds (A1) and (A2), were produced within the framework of the present invention analogously to the methods described in EP 1 178 105. Such isomeric mixtures were produced by means of fractionated distillation of the corresponding reaction product mixture, wherein, depending on the distillation conditions, a plurality of different fractions of isomeric mixtures to be used according to the invention were obtained, which can be used according to the invention as constituent (a). Alternatively, the compounds (A1) and (A2) were firstly produced in (substantially) pure form and then the desired weight ratio of (A1) to (A2) was adjusted by mixing the corresponding quantity fractions of the two pure compounds (A1) and (A2).
The preferred embodiments of fragrance substance mixtures according to the invention, in particular the mass ratios designated preferred or particularly preferred, apply likewise and correspondingly to perfume oils according to the invention, perfumed products according to the invention and to methods according to the invention.
The modifying effects described in conjunction with the present invention, in particular the masking and intensifying effects, are observed most strongly and clearly when using the compounds (A-1) and (A-2) in the quantity ratios in relation to one another designated preferred or particularly preferred, i.e. the preferred isomeric mixtures given of the compounds (A-1) and (A-2) of the constituent (a).
These described effects also occur particularly significantly when the isomeric mixtures mentioned of the compounds (A-1) and (A-2) are combined with further constituents of a fragrance substance mixture according to the invention, a perfume oil according to the invention or a product perfumed according to the invention, in particular in the embodiments designated preferred or particularly preferred below.
The, or the further, musk fragrance substance(s) of the constituent (b) are fragrance substances which have a musk odour. Fragrance substances of this type are known to the person skilled in the art, as musk is a very important odour orientation in perfumery.
The further musk fragrance substances of constituent (b) are not isolongifolenyl methyl ethers and preferably not isolongifolenyl-C1-C4-alkyl ethers.
Isolongifolenyl-C1-C4-alkyl ethers (in accordance with the structure formula shown on the left below) or isolongifolenyl methyl ethers (in accordance with the structure formula shown on the right below) are taken to mean, in the scope of the present invention, all compounds, including all stereoisomers, of the following structure formulas:
wherein the radical “Alk” stands for an alkyl radical with 1 to 4 carbon atoms and “Me” (as generally conventional) signifies a methyl group.
The further musk fragrance substances of constituent (b) therefore differ from constituent (a).
According to the invention, the mass ratio of the total quantity of further musk fragrance substances of constituent (b) to the total quantity of compounds of constituent (a) is in the range from 3:2 to 20:1, preferably in the range from 3:2 to 15:1, particularly preferably in the range from 2:1 to 12:1.
Fragrance substance mixtures preferred according to the invention, preferably perfume oils, contain two, three, four, five or more different musk fragrance substances as constituent (b), each of the musk fragrance substances preferably being selected independently of the other musk fragrance substances from the group of macrocyclic musk fragrance substances, the nitro-musk fragrance substances (aromatic musk fragrance substances with nitro group(s)), polycyclic musk fragrance substances and/or alicyclic musk fragrance substances.
The or the further musk fragrance substance(s) of constituent (b) are preferably selected from the group of macrocyclic musk fragrance substances, the nitro-musk fragrance substances (aromatic musk fragrance substances with nitro group(s)), polycyclic musk fragrance substances and/or alicyclic musk fragrance substances, preferably one, two, three or more musk fragrance substances from the following Table 1.
Fragrance substance mixtures according to the invention containing the compounds (A-1) and (A-2) and one or more further musk fragrance substances of constituent (b), preferably in which the mass ratio of the total quantity of further musk fragrance substances of constituent (b) to the total quantity of compounds (A-1) and (A-2) (constituent (a)) is in the quantity ratios given above (in particular given as preferred or particularly preferred), exhibit a modified, overall improved odour quality with regard to the undesired notes of the musk fragrance substances of constituent (b).
In comparison to an otherwise identically composed comparative fragrance substance mixture, which does not contain the compounds (A-1) and (A-2), the fragrance substance mixtures according to the invention exhibit less pronounced metallic notes, i.e. the metallic notes, in particular the pressing iron note, of the musk fragrance substances of constituent (b) are masked, i.e. partially or even completely reduced, by the presence of compounds (A-1) and (A-2) of the constituent (a).
In addition, by adding the compounds (A-1) and (A-2) a certain, mostly moderate to averagely strongly pronounced increase in the odour intensity (i.e. the total odour intensity) of a fragrance substance mixture containing one or more musk fragrance substances can be achieved. The epimeric compounds (A-1) and (A-2) act, in particular in the isomeric ratios given above, as “enhancers” or “boosters” for musk fragrance substances and for fragrance substance mixtures and perfume oils containing one or more musk fragrance substances.
The musk fragrance substance(s) in the scope of the present invention are preferably selected from the following Table 1:
Further preferred as part of constituent (b) are polycyclic and/or macrocyclic musk fragrance substances, whereupon macrocyclic musk fragrance substances, in particular, have proven to be particularly advantageous in the sense of the invention, which are preferably in turn selected from the group consisting of macrocyclic C14-C18 ketones and macrocyclic C14-C18 lactones, the ketone or lactone having a ring size of 15 to 17 ring atoms and having no, one or two oxygen atoms in the ring.
Most preferred are fragrance substance mixtures according to the invention, the constituent (b) of which comprises or consists of:
In a preferred embodiment, constituent (b) is selected from the group consisting of 15-pentadec-(11/12)-enolide (Globalide®), ethylene brassylate and oxacyclohexadecan-2-one (Macrolide®) and mixtures thereof.
According to the above statements, the present invention relates to a method for modifying, preferably for reducing or suppressing, a metallic note of one or more musk compounds, preferably of one or more macrocyclic musk compounds, comprising the following step:
A fragrance substance mixture according to the invention, preferably a perfume oil according to the invention, in addition to the constituents (a) and (b), preferably contains as a further constituent
A fragrance substance mixture according to the invention, preferably a perfume oil according to the invention, in addition to the constituents (a) and (b), preferably contains, as a further constituent
In a fragrance substance mixture according to the invention, preferably a perfume oil according to the invention, the mass ratio of the total quantity of terpene alcohols (constituent (c)) to the total quantity of compounds (A-1) and (A-2) (constituent (a)) is greater than or equal to 1:1, preferably greater than or equal to 2:1, more preferably greater than or equal to 3:1, particularly preferably greater than or equal to 4:1.
The mass ratio of the total quantity of terpene alcohols (constituent (c)) to the total quantity of compounds (A-1) and (A-2) (constituent (a)) is preferably in the range from 3:1 to 15:1, particularly preferably in the range from 4:1 to 10:1.
In particular when adjusting the aforementioned mass ratios of the total quantity of terpene alcohols (constituent (c)) to the total quantity of compounds (A-1) and (A-2) (constituent (a)) in a fragrance substance mixture according to the invention or a perfume oil according to the invention, the olfactory quality is improved overall. By adding constituent (c) not only are the odour notes particular to the terpene alcohol(s) of constituent (c) added to a fragrance substance mixture according to the invention or a perfume oil according to the invention, but an odour profile going beyond this and more complex overall is produced. Furthermore, an unexpected olfactory rounding and a further intensification of the odour impression can be observed.
The terpene alcohols of constituent (c) may be of natural or synthetic origin. In the case of a natural origin, they may be part of a corresponding essential oil or have been enriched or isolated from one such.
A fragrance substance mixture according to the invention, preferably a perfume oil according to the invention, in addition to constituents (a) and (b) and optionally (c), preferably contains as a further constituent

The following mixtures used (Mix1), (Mix2) and (Mix3) of the compounds (A1) and (A2) to be used according to the invention were produced analogously to the methods described in EP 1 178 105, the isomeric mixtures having been obtained either by means of fractionation of the corresponding reaction mixtures or the compounds (A1) and (A2) were initially produced in as pure a form as possible and then the respective weight ratio of (A1) to (A2) were adjusted in a targeted and precise manner by mixing the corresponding quantity fractions of the two pure compounds (A1) and (A2).
The mixture (Mix1) used below contained the compounds (A1) and (A2) in the weight ratio 3.6:1. The quantity of the two compounds (A1) and (A2) was 96.1% by weight, based on the total weight of (Mix1).
The mixture (Mix2) used below contained the compounds (A1) and (A2) in the weight ratio 4.5:1. The quantity of the two compounds (A1) and (A2) was 97.5% by weight, based on the total weight of (Mix2).
The mixture (Mix3) used below contained the compounds (A1) and (A2) in the weight ratio 5.8:1. The quantity of the two compounds (A1) and (A2) was 98.2% by weight, based on the total weight of (Mix3).
The perfume oils according to the invention P1, P2, P3, P4, P5, P6, P7, P8, P9, P10, P11 and P12 from the above perfume oil examples P1 to P12 were in each case incorporated separately into the following formulations.
The olfactory effects observed in the respective perfume oil were in each case also observed in the following formulations.
5 g Accurel (porous homo-polypropylene powder with a 75% cavity fraction, product of Akzo Nobel Faser AG, Obernburg, Germany) are loaded with 15 g of the perfume oil, perfume oil P1, P2, P3, P4, P5, P6, P7, P8, P9, P10, P11 and P12 by mixing the constituents under a vacuum. The resulting powder is then stirred at normal pressure with 4.5 g water, so mixture M1 is obtained. In a separate vessel, 2.5 g carrageenan, 0.3 g chloroacetamide and 0.5 g calcium chloride dihydrate are dissolved in 62 g water while heating at a maximum of 75° C. Mixture M1 is introduced into this solution while stirring and homogenised. The resulting, preferably still warm mixture is poured into the desired mould (spheres, semi-spheres, pads, cylinders, cuboids, cubes, shells or the like). After cooling to about 20° C., air fresheners in gel form are obtained, the loading of which with the respective perfume oil being about 20% by weight based on the total weight of the air freshener.
