Abstract

The invention relates to a perfume composition containing at least one odor modulator compound and a 1-aza-3,7-dioxabicyclo [3.3.0] octane 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 the use of at least one odor modulator compound and at least one 1-aza-3,7-dioxabicyclo [3.3.0] octane compound to increase the fragrance intensity of the perfume composition.

Description

The invention relates to a perfume composition containing at least one odor modulator compound and at least one 1-aza-3,7-dioxabicyclo [3.3.0] octane compound (bicyclic oxazolidine) for providing a long-lasting intense fragrance 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 and for prolonging the fragrance 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 associated with a low intensity of fragrance and also means that the fragrance can not be perceived after a relatively short time.

The prior art has hitherto disclosed only technologies which can only partially compensate for the above-mentioned disadvantages, and e.g. 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 1 263 405 B1 describes mixtures of oligomeric silicic acid esters which contain residues of perfume alcohols and are suitable for the long-lasting scenting of detergents and cleaners, since they release the perfume alcohols on hydrolysis.

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 both an initial high and a long-lasting high scent intensity. It was also an object of the present invention to provide a perfume composition which can be stably incorporated into consumer products to be perfumed and which meets the needs of consumers for resource-saving products.

This object has been achieved by a perfume composition containing

• a. at least one odor modulator compound, each individual odor modulator compound i. based on the total perfume composition, in an amount of 2 wt .-% to 0.000001 wt .-% is contained and ii. contains at least 1 heteroatom, wherein the at least one heteroatom is selected from N, O, S, Si, Se, F, Cl, Br or I and iii. has a molecular weight of less than 250 g mol ^-1 , and wherein the perfume composition has an efficiency factor of at least 1.15 by the at least one odor modulator compound, the efficiency factor being calculated according to the following formula:
  
  with E = efficiency factor and P = number of persons with an olfactory experience who have evaluated the perfume composition with odor modulator compound (PGMV) or without odor modulator compound (P) more intensively, the sum of P _GMV and P being at least 34, and
• b. at least one 1-aza-3,7-dioxabicyclo [3.3.0] octane compound according to the general formula (I)
  
  wherein - R ¹ and R ^{3 are} each independently hydrogen or a radical of 1 to 10 carbon atoms; and R ² and R ⁴ each independently represent radicals having from 1 to 25 carbon atoms; and R ⁵ and R ⁷ each independently represent hydrogen or a radical having 1 to 6 carbon atoms; and - R ^{6 is} hydrogen or a radical having 1 to 8 carbon atoms, wherein - one or more methyl groups, methylene groups, methine groups or quaternary carbon atoms of the radicals R ¹ to R ^{7 may} each be independently substituted by heteroatoms; and - at least one of the structural fragments -CR ¹ R ² - or -CR ³ R ⁴ - of the general formula (I) has arisen from a fragrance aldehyde or perfume ketone; and - if one of the structural fragments -CR ¹ R ² - or -CR ³ R ⁴ - emerged from a Duftstoffketon the radicals R ¹ and R ² or the radicals R ³ and R ^{4 of} this structural fragment may be wholly or partly an integral part of a ring ,

It has surprisingly been found that the fragrance intensity of a perfume composition according to the invention containing at least one odor modulator compound and at least one 1-aza-3,7-dioxabicyclo [3.3.0] octane compound is not only initial but also sustainable, usually even in synergistic Way, is increased. Therefore, by using an odor modulator compound and a 1-aza-3,7-dioxabicyclo [3.3.0] octane compound in a perfume composition of the present invention, the amount of perfume composition in a consumer product such as textile treatment agent, detergent, cosmetic or adhesive can be significantly lowered without thereby reducing the intensity of the fragrance or substantially altering the fragrance profile of the perfume composition. In addition, perfume compositions of the present invention can be stably incorporated into common consumer products and highly concentrated consumer products due to the smaller amount necessary to achieve the same fragrance intensity over 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 and consumer products 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 more preferred numeric ranges are specified in this format, it is It goes without saying that all areas that result from the combination of the different 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. "At least one odor modulator compound" therefore means, for example, one or more different odor modulator compounds, i. 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" or "at least one 1-aza-3,7-dioxabicyclo [3.3.0] octane compound", such as the odor threshold, amounts or ratios, apply to each individual odor modulator compound or each individual 1-aza-3,7-dioxabicyclo [3.3.0] octane compound. Thus, for example, if two odor modulator compounds / 1-aza-3,7-dioxabicyclo [3.3.0] octane compound are included in a specific amount range in the perfume composition, this means that both the first odor modulator compound and the first 1-aza-3, 7-dioxabicyclo [3.3.0] octane compound in the specific amount range, and the second odor modulator compound / the second 1-aza-3,7-dioxabicyclo [3.3.0] octane compound is contained in the specific amount range.

The terms "1-aza-3,7-dioxabicyclo [3.3.0] octane compound" and "bicyclic oxazolidine derivative" or "bicyclic oxazolidine" are used synonymously in the context of the present invention and stand for a compound according to the general formula (I).

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 be present in the form of a fragrance precursor compound, in the form of a fragrance depot system or as a free fragrance. 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 acquires a certain depth, which the person skilled in the art 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 and at least one 1-aza-3,7-dioxabicyclo [3.3.0] octane compound. 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 in the context of the present invention, however, despite its low use concentration has a significant influence on the consumer perceived fragrance intensity of the perfume composition according to the invention, so that, for example, a smaller amount of Perfume composition can be used to achieve the same fragrance intensity as in a conventional perfume composition without odor modulator compound and without 1-aza-3,7-dioxabicyclo [3.3.0] octane 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.

dividiert, wodurch der Effizienzfaktor (E) erhalten wird. Eine Geruchsmodulatorverbindung steigert die Duftintensität der erfindungsgemäßen 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. An odor modulator compound increases 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. Subsequently, the number of persons with an olfactory education who have evaluated the perfume composition with an odor modulator compound more intensively (PGMV) than the number of persons with an odor who has rated the perfume composition without an odor modulator compound as more intense (P) according to the formula

divided, whereby the efficiency factor (E) is obtained. An odor modulator compound increases the fragrance intensity of the perfume composition according to the invention so that the efficiency factor has at least a 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.

Although the specified names of the odor modulator compounds are fundamentally unambiguous within the present application and the skilled person has no problems identifying the corresponding substances, the CAS numbers of the odor modulator compounds have been indicated for the sake of simplicity. If, contrary to expectation, the specified name does not match the specified CAS number, the CAS number applies in case of doubt. Only in cases where it is obvious that the CAS number is incorrect, the given name is preferable to the CAS number. This rule also applies to all other connections within the present application for which both a systematic or trivial name and a CAS number are given.

wobei

• – X für Stickstoff, Schwefel oder CR¹⁰; und
• – Y für Sauerstoff, Schwefel oder NR¹²; und
• – R⁸, R⁹ und R¹² jeweils unabhängig voneinander für Wasserstoff oder Reste mit 1 bis 6 Kohlenstoffatomen; und
• – R¹⁰ und R¹¹ jeweils unabhängig voneinander für Wasserstoff oder Reste mit 1 bis 9 Kohlenstoffatomen stehen, wobei
• – der Ring der Formel (II) an den mit unterbrochenen Strichen verknüpften Positionen jeweils unabhängig voneinander Doppelbindungen enthalten kann, mit der Maßgabe, dass die mindestens eine Geruchsmodulatorverbindung, wenn X für Stickstoff steht, zwischen X und dem Kohlenstoffatom des Rings der Formel (II), das mit R¹¹ verknüpft ist, eine Doppelbindung enthält; und
• – die mit R⁸ und R⁹ verknüpften Kohlenstoffatome des Rings der Formel (II) gemeinsam Bestandteil eines annelierten fünf- oder sechsgliedrigen Rings sein können, wobei die Reste R⁸ und R⁹ jeweils unabhängig voneinander ganz oder teilweise integraler Bestandteil des annelierten Rings sind; und
• – ein oder mehr Methylgruppen, Methylengruppen, Methingruppen oder quartäre Kohlenstoffatome der Reste R⁸ bis R¹² jeweils unabhängig voneinander durch Heteroatome substituiert sein können.

In a preferred embodiment of the invention, the at least one odor modulator compound is an odor modulator compound according to the general formula (II)

in which

• X is nitrogen, sulfur or CR ¹⁰ ; and
• Y is oxygen, sulfur or NR ¹² ; and
• R ⁸ , R ⁹ and R ^{12 are} each independently hydrogen or radicals of 1 to 6 carbon atoms; and
• - R ¹⁰ and R ^{11 are} each independently hydrogen or radicals having 1 to 9 carbon atoms, wherein
• The ring of the formula (II) may each independently contain double bonds at the positions linked with broken lines, with the proviso that the at least one odor modulator compound, when X is nitrogen, is between X and the carbon atom of the ring of the formula (II) which is linked to R ¹¹ contains a double bond; and
• - The carbon atoms of the ring of the formula (II) linked to R ⁸ and R ^{9 may} together form part of an annelated five- or six-membered ring, wherein the radicals R ⁸ and R ^{9 are} each, independently of one another, wholly or partly an integral part of the fused ring; and
• - One or more methyl groups, methylene groups, methine groups or quaternary carbon atoms of the radicals R ⁸ to R ^{12 may} each be independently substituted by hetero atoms.

In the context of this embodiment, in the ring of general formula (II), the positions associated with broken lines may each independently have double bonds. However, double bonds are especially absent if, due to the choice of X or the radicals R ⁸ to R ^11, the natural valence of the atoms participating in the double bond are already saturated. This means that the atoms involved in the double bond must always be uncharged. For example, when X represents sulfur, the bond between X and the carbon atom directly linked to R ¹¹ can not be a double bond. Even if one of the radicals R ⁸ to R ^{11 forms} a double bond to one of the carbon atoms in the ring of the general formula (II), the corresponding atom in the ring can no longer be involved in a double bond within the ring

For the purpose of this embodiment, the carbon atoms of the ring of the formula (II) linked to R ⁸ and R ^{9 may} together form part of an annelated five- or six-membered ring, wherein the radicals R ⁸ and R ^{9 are} each, independently or in each case, an integral part of the fused ring Rings are. Annelated in this context means that two carbon rings share a carbon-carbon bond, namely the carbon atoms of the ring of formula (II) linked to R ⁸ and R ⁹ , which bond may be a single or double bond. When the radicals R ⁸ and R ^{9 are} only partially integral with the fused ring, the non-integral constituents of the ring of the radicals R ⁸ and R ^{9 may,} for example, be in the form of a side chain of the fused ring.

The at least one odor modulator compound according to the general formula (II) preferably contains one to four heteroatoms selected from the group of nitrogen, oxygen or sulfur.

Preferred radicals R ⁸ to R ¹² in the general formula (II) are, for example, alkyl groups, alkenyl groups, aryl groups, hydroxy groups, alkanol groups, acyl groups, (alkyl) ester groups, (alkyl) thiol groups, thioether groups and (alkyl) aldehyde groups. In principle, the different functional groups can be present in any combination in the radicals R ⁸ to R ¹² , but it is preferred in the context of this embodiment that when Y = nitrogen and X = CR ¹⁰ , the radicals R ⁸ and R ^{9 are} not complete or partially integral part of a six-membered ring.

In a further preferred embodiment of the invention, the at least one odor modulator compound is an odor modulator compound according to the general formula (III),

in which

• X is nitrogen or CR ¹⁵ ; and
• Y is nitrogen, CR ¹⁸ or CR ¹⁸ R ¹⁹ ; and
• Each of R ¹³ and R ¹⁵ independently represents hydrogen or groups of 1 to 10 carbon atoms; and
• - R ¹⁴ and R ¹⁶ to R ^{19 are} each independently hydrogen or radicals having 1 to 4 carbon atoms, wherein
• The ring of formula (III) may each independently contain double bonds at the positions connected with broken lines, with the proviso that the at least one odor modulator compound, when X or Y is nitrogen, is between X and the carbon atom of the ring of formula (II) III) linked to R ¹⁴ , or between Y and the carbon atom of the ring of formula (III) linked to R ¹³ , contains a double bond; and
• - The carbon atoms of the ring of the formula (III) linked to R ¹³ and R ^{14 may} together form part of an annelated five- or six-membered ring, wherein the radicals R ¹³ and R ^{14 are} each, independently of one another, wholly or partly an integral part of the fused ring; and
• One or more methyl groups, methylene groups, methine groups or quaternary carbon atoms of the radicals R ¹³ to R ^{19 may} each independently be substituted by heteroatoms; and
• When Y is CR ¹⁸ R ¹⁹ , between the carbon atom of the ring attached to R ¹³ and Y is not a double bond.

In the context of this embodiment, in the ring of general formula (III), the positions associated with broken lines may each independently have double bonds. However, double bonds are particularly absent if, due to the choice of Y or the radicals R ¹³ to R ^18, the natural valence of the atoms involved in the double bond are already saturated. This means that the atoms involved in the double bond must always be uncharged. When one of R ¹³ to R ^{18 forms} a double bond to one of the carbon atoms in the ring of general formula (III), the corresponding atom in the ring may no longer be involved in a double bond within the ring.

The carbon atoms of the ring of the formula (III) linked to R ¹³ and R ¹⁴ may together form part of an annelated five- or six-membered ring, wherein the radicals R ¹³ and R ^{14 are} each, independently of one another, wholly or partly an integral part of the fused ring. Annelated in this context means that two carbon rings share a carbon-carbon bond, namely the carbon atoms of the ring of formula (III) linked to R ¹³ and R ¹⁴ . When the radicals R ¹³ and R ^{14 are} only partially integral with the fused ring, the non-integral constituents of the ring of radicals R ¹³ and R ¹⁴ may be in the form of a side chain of the fused ring, for example.

Open-chain in the context of the present invention means that none of the radicals R ²⁵ to R ²⁷ as such forms a ring or participates in a ring and also no rings between the individual radicals R ²⁵ to R ^{27 are} formed.

When one or more methyl groups, methylene groups, methine groups or quaternary carbon atoms of the radicals R ¹ to R ²⁷ are substituted by heteroatoms, this means that the corresponding group is exchanged for 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 ²⁷ can be arbitrarily substituted by heteroatoms, but with the exception of di- or polysulfides and diazo compounds, no two directly adjacent groups are simultaneously substituted by heteroatoms.

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. For example, detailed 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 specially designed room (measuring room) for the olfactometer, which is odor-neutral, can be well ventilated and, if necessary, can 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).

In a further preferred embodiment of the invention, the at least one odor modulator compound is selected from pyrroles, pyridines, pyrazines, thiols, sulfides, thiazoles, thiophenes, furans, oxazolines, oxazoles and / or oxathions.

It has been found according to the invention that the combination of at least one bicyclic oxazolidine of fragrance aldehydes and / or fragrance ketones, which results in a reduction of the vapor pressure of the fragrance aldehydes and fragrance ketones and an extension of the fragrance impression, produces a particularly long-lasting and intense fragrance impression with at least one odor modulator compound according to the invention. Moreover, the use of at least one bicyclic oxazolidine improves the deposition of the fragrance / fragrances bound in the at least one bicyclic oxazolidine on soft surfaces such as textiles or skin, or hard surfaces such as glass, ceramic or metal.

mit Verbindungen der allgemeinen Formeln R¹-C(=O)-R² und R³-C(=O)-R⁴ unter Ringschluss. The compounds of the general formula (I) according to the invention are obtained by reacting compounds of the general formula (VI)

with compounds of the general formulas R ¹ -C (= O) -R ² and R ³ -C (= O) -R ⁴ with ring closure.

The compounds of general formula (VI) are derived from 2-amino-1,3-propanediol. By preparing the bicyclic oxazolidines, it is possible to achieve a high degree of loading of the 2-amino-1,3-propanediols, so that the use of small amounts of 2-amino-1,3-propanediols is possible. Thus, an extension of the scent impression can be achieved even with small amounts of 2-amino-1,3-propanediols, which can lead to cost advantages and also avoids the entry of larger quantities of chemicals in detergents, softeners or cosmetics. The combination according to the invention of the at least one bicyclic oxazolidine with the at least one odor modulator compound further enhances this effect, since even small amounts of the fragrance released from the bicyclic oxazolidine lead to a high odor intensity.

It is also possible according to the invention to use mixtures of singly and doubly closed compounds based on the 2-amino-1,3-propanediols, according to the general formulas (VII) and (I). It is preferred to achieve a high degree of loading of the 2-amino-1,3-propanediols, so that preferably used two-reacted 2-amino-1,3-propanediols according to the general formula (I).
