Field of invention

The present invention relates to new bicyclic compounds as aroma chemicals.

Specifically, it relates to the use of bicyclic compounds as an aroma chemical and also for enhancing and/or modifying the aroma of a composition.

Background

Aroma chemicals, especially fragrances, are of great interest, especially in the field of cosmetics, 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 organoleptic properties that resemble more expensive natural fragrances, or which have novel and interesting organoleptic profiles.

Despite a large number of already existing synthetic aroma chemicals (fragrances and flavorings), 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 organoleptic 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 fragrances, a higher stability under certain application conditions, a higher extendibility, a better higher substantivity.

There is an increased need for aroma chemicals which can impart a sensory impression, especially impressions selected from the group consisting of dried fruit note, minty note, violet note, tobacco note, Ionone note, Amber note , woody note , dusty note, peppery note, cedarwood note, sweet note, dry note and acetic note to a composition. Such properties are of special interest for compositions such as for example body care compositions, hygiene articles, cleaning compositions, textile detergent compositions and compositions for scent dispensers.

Of special interest are aroma chemicals, which can impart one or more distinct sensory impressions to a composition, thereby contributing to a rich and interesting sensory profile, especially an olfactory profile of the composition. In this regard, aroma chemicals which can impart a dried fruit note, minty note, violet note, tobacco note, Ionone note, Amber note, woody note, dusty note, peppery note, cedarwood note, sweet note, dry note and acetic note, or any combination of two or more of these notes are of major interest. In addition, the substantivity as well as the tenacity are of special interest in order to obtain a long-lasting odiferous impression in the composition as well as to the surface which is treated with the composition.

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

It is an object of the presently claimed invention to provide substances which can be used as an aroma chemical either alone or as mixtures in compositions, in particular odorintensive substances having a pleasant odor are sought. Furthermore, they should be combinable with other aroma chemicals, allowing the creation of novel advantageous sensory profiles and can be used in compositions.

It is an object of the presently claimed invention to provide a new aroma chemical or mixture of aroma chemicals which has pleasant olfactory impression; preferably a combination of two or more of the impression which are selected from the group consisting of dried fruit note, minty note, violet note, tobacco note, Ionone note, Amber note, woody note, dusty note, peppery note, cedarwood note , sweet note, dry note and acetic note.

A further object of the present invention is that the aroma chemicals should be obtainable from readily available starting materials, allowing their fast and economic manufacturing.This is of special interest while using the aroma chemicals in compositions such as care compositions, hygiene articles, cleaning compositions, textile detergent compositions and compositions for scent dispensers.

This object is achieved by the provision of the novel compound which are bicyclic compounds having 10 to 16 carbon atoms.

Definitions

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

The term “aroma chemical” denotes a substance which is used to obtain a sensory or organoleptic (used interchangeably herein) impression and comprises its use to obtain an olfactory and/or a flavor impression. The term "olfactory impression" or “note” (used interchangeably here) denotes an odor impression without any positive or negative judgement, while the term “scent impression” or “fragrance impression” or “aroma 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.

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 being a composition, which predominately induces an odor impression, a flavor composition being a composition, which predominantly induces a taste impression.

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.

The general hedonistic expressions "advantageous sensory properties" or "advantageous organoleptic properties" describe the niceness and conciseness of an organoleptic impression conveyed by an aroma chemical. "Niceness" and "conciseness" are terms which are familiar to the person skilled in the art, such as 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 typically tart apple 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.

The expressions "combination of, "in combination with" or "combined with" when used herein referring to the compositions, methods or the use of two compounds, take account of the fact that the two compounds do not need to be used in the form of a physical mixture of said compounds but can be used (e.g., added) separately. Where the compounds are used separately, they can be used (e.g. added) sequentially (i.e. one after the other) in any order, or concurrently (i.e. basically at the same time).

The term “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.

The intensity can be determined via a threshold value determination. A threshold value of an odor 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.

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.

The terms “the invention relates to” and “the invention is directed to” are used synonymously throughout the invention.

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.

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. 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.

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.

Unless specified otherwise herein, a "compound" described herein relates to the compounds defined by the general formula (la) or formula (lb) or a mixture thereof.

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.

One embodiment of the invention is therefore directed to a composition comprising the compound of the present invention and at least one deodorant-active agent. In a preferred embodiment, the deodorant-active agent is selected from the groups consisting of antiperspirants, esterase inhibitors, antibacterial agents and mixtures of two or more of the aforementioned.

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, zinc glycinate and mixtures of two or more of the aforementioned.
