Abstract

The invention relates to a perfume composition containing at least one odor modulator compound for increasing the fragrance intensity of the perfume composition and a consumer product containing such a perfume composition. Furthermore, the invention relates to a method for increasing the fragrance intensity of the perfume composition and to the use of at least one odor modulator compound for increasing the fragrance intensity of the perfume composition.

Description

The invention relates to a perfume composition containing at least one odor modulator compound for increasing the fragrance intensity of the perfume composition and a consumer product containing such a perfume composition. Furthermore, the invention relates to a method for increasing the fragrance intensity of the perfume composition and to the use of at least one odor modulator compound for increasing the fragrance intensity of the perfume composition.

Demands on consumer products such as textile treatment products, detergents, cosmetics or adhesives have become more demanding in recent years as consumers expect more and more powerful products on the one hand, but on the other hand due to regulatory constraints or consumers' desire for more sustainable and environmentally friendly products the acceptance of commodity-intensive products decreases.

This trend leads to the concentration of consumer products, which means that the active ingredient content in the corresponding products is higher, whereas the amount of the consumer product to be used by the consumer is smaller - if the consumer product is used professionally. However, this concentration can lead to disadvantages in the incorporation and / or performance of certain ingredients, especially perfume compositions. For example, the high concentration of perfume composition necessary to achieve a particular scent intensity can result in the perfume composition not being able to be stably incorporated into the consumer product. The consequence of this development is that often only small amounts of a perfume composition can be incorporated into the consumer product, but this is accompanied by a low intensity of scent.

The prior art has so far disclosed only technologies that can only partially compensate for the above-mentioned disadvantages and, for example, lead to a prolonged fragrance or at a defined time to a strong fragrance release.

This is how the European patent describes EP 1 976 855 B1 bicyclic oxazolidines which are used as a fragrance precursor and release a fragrance by slow hydrolysis, generating a long-lasting fragrance. However, a direct increase in the fragrance intensity of the entire perfume composition can not be achieved by this technology.

The European patent EP 2 087 089 B1 describes the use of perfume microcapsules as a depot system, whereby the capsules break open at a defined time and provide an intense fragrance in the short term. However, this technology is associated with great technical effort and high costs and the capsule wall material has no direct function after breaking the capsules.

The international patent application WO 2012/162331 A2 describes the use of special fragrance chords with a specific odor intensity value (OIS), the selected fragrances having a particularly high odor intensity (OIR). However, based on this technology, not every fragrance profile can be generated, as the choice of fragrances is severely limited.

The object of the present invention was therefore to provide a perfume composition with an arbitrary but specific scent profile which has a higher scent intensity than conventional perfume compositions, without necessarily relying on complex technologies such as perfume precursors or depot systems.

This object has been achieved by a perfume composition comprising at least one odor modulator compound according to the general formula (I)

in which

• X is CHR ² , sulfur or a carbonyl group; and
• Y is CHR ⁴ , sulfur, CR ⁴ R ⁵ or a carbonyl group; and
• Each of R ¹ , R ² and R ⁵ independently represents hydrogen or groups of 1 to 4 carbon atoms; and
• - R ³ and R ^{4 are} each independently hydrogen or radicals having 1 to 8 carbon atoms, wherein
• - The radicals R ¹ to R ^{5 are} open-chain; and
• - One or more methyl groups, methylene groups, methine groups or quaternary carbon atoms of the radicals R ¹ to R ^{5 may} each be independently substituted by hetero atoms.

It has surprisingly been found that the fragrance intensity of a perfume composition containing at least one odor modulator compound according to the invention is increased. Thus, by using an odor modulator compound of the present invention in a perfume composition, the amount of perfume composition in a consumer product such as fabric treatment, cleaning, cosmetic or adhesive can be significantly reduced without reducing the intensity of the fragrance or substantially altering the fragrance profile of the perfume composition. In addition, perfume compositions of the present invention, because of the smaller amount necessary to achieve the same scent intensity, can be more stably incorporated into common consumer products than conventional perfume compositions.

These and other features and advantages of the invention will become apparent to those skilled in the art from a study of the following detailed description and claims. It is to be understood that the examples herein are intended to describe and illustrate the invention, but not to limit it, and in particular that the invention is not limited to the examples.

All percentages are by weight unless stated otherwise (% by weight). Quantities of ingredients of the perfume compositions described herein, unless otherwise indicated, always refer to the amount of the pure ingredient. Furthermore, amounts referring to at least one ingredient always mean the total amount of that type of ingredient contained in the composition, unless explicitly stated otherwise.

Numeric ranges indicated in the format "from x to y" include the above values. If multiple preferred numeric ranges are specified in this format, it is understood that all ranges resulting from the combination of the various endpoints are also covered.

"At least one" as used herein refers to 1 or more, for example, 2, 3, 4, 5, 6, 7, 8, 9 or more. In the context of ingredients of the perfume compositions described herein, this indication does not refer to the absolute amount of molecules but to the nature of the ingredient. Thus, "at least one odor modulator compound" means, for example, one or more different odor modulator compounds, that is, one or more different types of odor modulator compounds. Together with quantities, the quantities given refer to the total amount of the corresponding designated type of ingredient, unless otherwise specified.

All features relating to "at least one odor modulator compound", such as the odor threshold, ClogP value, quantities, or ratios, apply to each individual odor modulator compound. Thus, for example, if two odor modulator compounds are contained in a specific amount range in the perfume composition, it means that both the first odor modulator compound is contained in the specific tonnage range and the second odor modulator compound is contained in the specific tonnage range.

For the purposes of the present invention, a perfume composition comprises at least one perfume which contributes substantially to the achievement of a specific fragrance profile. In the context of the invention, a fragrance may also be present in the form of a fragrance precursor compound or in the form of a fragrance depot system. In addition, a perfume composition additionally comprises all adjuvants known in the art which themselves have no perceptible odor, but result in a better meterability, a prolonged fragrance or a similar effect, such as, for example, solvents or adhesion promoters.

The terms fragrance and perfume are used synonymously in the context of the present invention. A fragrance is a compound which has a characteristic odor and contributes to the achievement of a specific fragrance profile of a perfume composition. Fragrances also include those compounds which alter the fragrance profile of a perfume composition such that the fragrance has a certain Depth receives what the skilled person usually knows as the complexity of a fragrance. However, a fragrance within the meaning of the present invention has no direct influence on the fragrance intensity of the perfume composition, as long as the perfume composition is used at a constant concentration.

The fragrance profile of a perfume composition is the specific fragrance a consumer perceives due to the fragrance it contains. Without being in any way limited to a fragrance, for example, flowery, spicy, sweet, sour, tart, fresh, woody, fruity, leathery, oriental, animal, chypre, fougere, citrus, edible, green, musky, ozone, aldehydic, smell agriculturally, aromatic or marine, which can be achieved by the special selection of the individual fragrances in the perfume composition complex fragrance profiles and a floral fragrance can smell, for example, rose, violet or lavender. A scent profile is therefore the characteristic scent of each perfume composition, which results from the fragrances used.

An odor modulator compound (GMV) in the context of the present invention is a compound which, although having an inherent odor, but in the concentration used, under the test conditions given below, not or not significantly to a change in the fragrance profile of the perfume composition containing at least one odor modulator compound , contributes. An insignificant change in the fragrance profile of the perfume composition means that although the fragrance profile may differ slightly from the original fragrance profile of the perfume composition, it is still recognized by the skilled person as the original fragrance profile. An odor modulator compound according to the present invention, however, despite its low use concentration, has a significant influence on the consumer perceived fragrance intensity of the perfume composition, so that, for example, a smaller amount of the perfume composition can be used to achieve the same fragrance intensity as in a conventional perfume composition without odor modulator compound , An odor modulator compound therefore, unlike a fragrance contained in a perfume composition, does not define the fragrance profile, but rather enhances the fragrance intensity of the fragrance profile of the perfume composition as defined by the fragrances. By virtue of the fact that the at least one odor modulator compound does not substantially change the fragrance profile of the perfume composition, in principle any desired fragrance profile can be realized without the disturbing side notes being perceived.

An odor modulator compound in the context of the present invention is subject to the general formula (I)

in which

• X is a CHR ² , sulfur or a carbonyl group; and
• Y is a CHR ⁴ , sulfur, CR ⁴ R ⁵ or a carbonyl group; and
• Each of R ¹ , R ² and R ⁵ independently represents hydrogen or groups of 1 to 4 carbon atoms; and
• - R ³ and R ^{4 are} each independently hydrogen or radicals having 1 to 8 carbon atoms, wherein
• - The radicals R ¹ to R ^{5 are} open-chain; and
• - One or more methyl groups, methylene groups, methine groups or quaternary carbon atoms of the radicals R ¹ to R ^{5 may} each be independently substituted by hetero atoms.

The radicals R ¹ to R ^{5 of} the at least one odor modulator compound of the general formula (I) are open-chain. Open-chain in the context of the present invention means that none of the radicals R ¹ to R ⁵ as such forms a ring or participates in a ring and also no rings between the individual radicals R ¹ to R ^{5 are} formed. However, open-chain means in particular not that the radicals R ¹ to R ^{5 can} not have double or triple bonds between two directly adjacent atoms.

Methylgruppen, Methylengruppen, Methingruppen oder quartäre Kohlenstoffatome der Reste R¹ bis R⁵ können grundsätzlich beliebig durch Heteroatome substituiert werden, jedoch werden mit Ausnahme von Di- oder Polysulfiden oder Diazoverbindungen keine zwei direkt benachbarten Gruppen gleichzeitig durch Heteroatome substituiert. Die mindestens eine Geruchsmodulatorverbindung im Sinne der vorliegenden Erfindung enthält vorzugsweise ein bis vier Heteroatome, ausgewählt aus der Gruppe Stickstoff, Sauerstoff oder Schwefel.One or more methyl groups, methylene groups, methine groups or quaternary carbon atoms of R ¹ to R ^{5 of} the at least one odor modulator compound may each be independently substituted by heteroatoms. Heteroatoms in the context of the present invention are selected from the group of nitrogen, oxygen, sulfur, Silicon, selenium, fluorine, chlorine, bromine or iodine. One or more methyl groups can be substituted by a heteroatom selected from the group nitrogen, oxygen, sulfur, silicon, selenium, fluorine, chlorine, bromine or iodine, one or more methylene groups can be selected by a heteroatom selected from the group nitrogen, oxygen, sulfur , Selenium or silicon, one or more methine groups may be substituted by a heteroatom selected from the group consisting of nitrogen or silicon, and one or more quaternary carbon atoms may be substituted by silicon. When one or more methyl groups, methylene groups, methine groups or quaternary carbon atoms of the radicals R ¹ to R ⁵ are substituted by heteroatoms, this means that the corresponding group is replaced by a heteroatom. Should free valences arise through the substitution of a methyl group, a methylene group or a methine group, these are in principle saturated with hydrogen. Thus, for example, a terminal methyl group besides a methylene group can be replaced by a hydroxy group or a sulfanyl group to give a methylene hydroxy group or a methylene thiol group. Similarly, an isopropyl group which is a radical having two methyl groups and a methine group or a derivative of the isopropyl group which is a group having a methyl group, a methylene group and a quaternary carbon atom may have, for example, the following substitution patterns:

In principle, methyl groups, methylene groups, methine groups or quaternary carbon atoms of the radicals R ¹ to R ⁵ can be substituted as desired by heteroatoms, but with the exception of di- or polysulfides or diazo compounds, no two directly adjacent groups are simultaneously substituted by heteroatoms. The at least one odor modulator compound in the context of the present invention preferably contains one to four heteroatoms selected from the group of nitrogen, oxygen or sulfur.

dividiert, wodurch der Effizienzfaktor (E) erhalten wird. Eine erfindungsgemäße Geruchsmodulatorverbindung steigert die Duftintensität der Parfümzusammensetzung so, dass der Effizienzfaktor mindestens einen Wert von 1.15 aufweist. In einer bevorzugten Ausführungsform weist der Effizienzfaktor mindestens einen Wert von 1.5, weiter bevorzugt einen Wert von mindestens 1.75 oder noch weiter bevorzugt sogar einen Wert von mindestens 2 auf.The at least one odor modulator compound according to the invention enhances the fragrance intensity of the perfume composition, which is described by the efficiency factor (E). The efficiency factor is a measure of the fragrance intensity of two identical fragrance combinations containing perfume compositions, wherein one of the two perfume compositions additionally contains at least one odor modulator compound in the context of the present invention. A group of at least 34 well-trained individuals assesses the intensity of both perfume compositions and determines the perfume composition smelling more intense than the other, with the intensity of the perfume compositions being evaluated by exactly 34 odorily trained persons in the embodiments of this invention. Thereafter, the number of persons trained in olfaction who have judged the perfume composition having an odor modulator compound to be more intense (P _GMV ) is expressed by the number of persons trained in olfaction who have rated the perfume composition without odor modulator compound more intense (P) according to formula

divided, whereby the efficiency factor (E) is obtained. An odor modulator compound according to the invention enhances the fragrance intensity of the perfume composition such that the efficiency factor is at least one value of 1.15. In a preferred embodiment, the efficiency factor has at least a value of 1.5, more preferably a value of at least 1.75 or even more preferably even a value of at least 2.

In a preferred embodiment of the invention, the perfume composition of the present invention contains one to six odor modulator compounds, preferably one to five odor modulator compounds, more preferably one to four odor modulator compounds, and most preferably one to three odor modulator compounds.

In a further preferred embodiment of the invention, the at least one odor modulator compound, based on the totality of all fragrances contained in the perfume composition in a weight ratio of not more than 1: 9, preferably not more than 1:49, more preferably not more than 1:99 and most preferably not more than 1: 299 used, wherein the ratio is always based on the at least one fragrance as such and not on a corresponding fragrance precursor compound or a fragrance depot system.

In yet another preferred embodiment of the invention, the at least one odor modulator compound is present in an amount of from 2% to 0.000001% by weight, preferably from 1.5% to 0.000001% by weight, more preferably 1.0% by weight. % to 0.000001 wt .-%, more preferably from 0.5 wt .-% to 0.000001 wt .-%, most preferably 0.25 wt .-% to 0.000001 wt .-%, wt .-% in each case based on the perfume composition.

The low ratio of the at least one odor modulator compound compared to the fragrances contained in the perfume composition and the small amounts of the individual odor modulator ensures that the fragrance profile of the perfume composition changed at most insignificant, so that the expert further recognizes the fragrance profile of the original fragrance. Moreover, it is advantageous from an ecological and economic point of view to use only small amounts of the at least one odor modulator compound.

In a further preferred embodiment of the invention, the at least one odor modulator compound is selected from sulfides, disulfides, trisulfides and polysulfides.

The octanol / water partition coefficient of an odor modulator compound is the ratio between its equilibrium concentration in octanol and in water. Since the distribution coefficients of the odor modulator compounds often have high values, for example 1000 or higher, they are more conveniently given in the form of their base 10 logarithm, one speaks of the so-called logP value.

The logP value of numerous odor modulator compounds is documented. However, the logP values are most conveniently calculated by the "CLOGP" program available from Daylight Chemical Information Systems, Inc., (Daylight CIS), Irvine, California. The "calculated logP values", the ClogP values which are the most reliable and widely used estimates for this physicochemical property, are used in the context of this invention in the selection of odor modulator compounds. In a further preferred embodiment of the invention, the at least one odor modulator compound has a ClogP value of less than 2.5, preferably less than 2.0. A small ClogP value is equivalent to a good water solubility of the at least one odor modulator compound under standard conditions according to IUPAC, ie 25 ° C and 1 bar air pressure. Due to the good water solubility of the at least one odor modulator compound, this can on the one hand well incorporated in an aqueous consumer product and distributed homogeneously and on the other hand, the evaporation of water, for. Example, when drying treated with a perfume composition according to the invention textiles, the entrained better at least one odor modulator compound in the gas phase, whereby the odor intensity of the perfume composition can be additionally enhanced.

The at least one odor modulator compound is preferably characterized by a low odor threshold (ODT). The odor threshold value is the lowest odor nor perceptible concentration of a substance. A simple technique for determining the odor threshold value is dynamic olfactometry, where a direct sensory evaluation of the compounds takes place. The odor threshold serves as a measure of the odor strength of a fragrance. The odor threshold (ODT) of the at least one odor modulator compound is determined according to DIN EN 13725: 2003 is and is preferably less than 100 ppb, preferably less than 75 ppb, more preferably less than 50 ppb, even more preferably less than 35 ppb, even more preferably less than 10 ppb and most preferably less than 1 ppb. detailed For example, information can be found in DIN EN 13725: 2003 , For the purpose of the present invention, the odor threshold value is measured by the following method: The olfactometer is placed in a room specially designed for the olfactometer, which is odor-neutral, can be well ventilated and can optionally be force-ventilated via an activated carbon filter. The volume fraction of carbon dioxide in the measuring room is less than 0.15 vol .-%, the air exchange rate is at least 4.4 m ³ / h per person. The temperature in the measuring room is 22 ± 3 ° C and is constant during the measurement. The measuring room is not exposed to direct sunlight and other disturbing sources of light and noise have been minimized as much as possible. The olfactometer and any devices that come into direct or indirect contact with the odor modulator compound to be evaluated must be odorless and are inert with respect to their reactivity with the odor modulator compounds, such as glass, stainless steel or PTFE. The airflow provided by the olfactometer must be at least 20 L / min, with the opening of the device at which the sensory evaluation is made so that the air velocity in the flowed-through orifice is at least 0.2 m / s. The olfactometer is checked regularly, at least every twelfth compound by a reference measurement with n-butanol as the reference compound. The assessment of the compounds will be carried out by at least four examiners, with the usual number of odor-trained men and women, all of whom are at least 16 years old. At the time of evaluation of the compounds, the examiners are not affected by disturbing factors such as contact with perfume, food, other stimulants or even by a cold or allergy. The odor modulator compound is used to prepare standardized dilute solutions in an odorless solvent, for example dipropylene glycol (DPG), with the lowest concentration well below the odor threshold. Subsequently, the solutions are measured by means of the olfactometer. The concentration of the compound to be evaluated is gradually increased, each concentration being doubled until the tester perceives an odor. Each odor modulator compound is measured three times each by each examiner and the arithmetic mean of all odor sensed concentrations forms the Odor Threshold (ODT).
