Description

[0028] In a preferred embodiment, the pulverulent composition according to the invention contains fillers, preferably maltodextrin.

[0029] In another preferred embodiment, the composition additionally contains flavouring agents, preferably menthol, vanillin, or fruit flavourings. The possibility of providing different flavouring agents in the composition allows different experiences to be created during use. For example, activating or also calming and soothing flavourings can be selected.

[0030] In a further preferred embodiment, the composition additionally contains a fluorescent dye, preferably a fluorescent food dye, in particular riboflavin, tartrazine, yellow orange S, cochineal red A, amaranth, or brilliant blue FCF. Preferably, the fluorescent dye can be excited by UV light, preferably with light of a wavelength between 200 nm and 400 nm, in particular 365 nm. By providing a fluorescent dye, the pulverulent composition is readily visible even in rooms illuminated only with black light (UV light), which makes it particularly easy to use in such environments.

[0031] In a particularly preferred embodiment, the composition contains: [0032] between 4% by weight and 40% by weight of taurine; [0033] between 2% by weight and 25% by weight of caffeine; [0034] between 1% by weight and 17% by weight of L-arginine; and [0035] between 1% by weight and 17% by weight of L-tryptophan.

[0036] In another particularly preferred embodiment, the composition consists of: [0037] between 4% by weight and 40% by weight of taurine; [0038] between 2% by weight and 25% by weight of caffeine; [0039] between 1% by weight and 17% by weight of L-arginine; [0040] between 1% by weight and 17% by weight of L-tryptophan; and [0041] ad 100% by weight of fillers, in particular maltodextrin.

[0042] Since the pulverulent compositions according to the invention are intended for nasal application, it is preferred that certain ingredients which are frequently found in foodstuffs or energy drinks are not present or are present only in low concentrations. Such ingredients may, among other things, irritate the nasal mucosa or lead to other undesirable effects.

[0043] It is therefore preferred that the composition according to the invention contains less than 10% by weight, preferably less than 5% by weight, even more preferably less than 1% by weight, even more preferably less than 0.1% by weight, most preferably no sweeteners. Sweeteners as used herein are understood to be sugar substitutes, i.e. food additives intended to provide a sweet taste to food. Sugars, such as maltodextrin, are not sweeteners in the sense of the invention. In a preferred embodiment, the sweeteners are sweetening substances, preferably selected from the group consisting of acesulfame, advantame, aspartame, cyclamate, neotame, sucralose, neohesperidin, saccharin, stevioside and thaumatin. In another preferred embodiment, the sweeteners are sugar substitutes, preferably sugar alcohols, in particular wherein the sugar substitutes are selected from the group consisting of sorbitol, mannitol, isomalt, maltitol, polyglycitol, lactitol, xylitol and erythritol.

[0044] Furthermore, it is preferred that the composition contains less than 10% by weight, preferably less than 5% by weight, even more preferably less than 1% by weight, even more preferably less than 0.1% by weight, most preferably no citric acid or citrates. It is further preferred that the composition contains less than 10% by weight, preferably less than 5% by weight, even more preferably less than 1% by weight, even more preferably less than 0.1% by weight, even more preferably less than 0.01% by weight, most preferably no nicotine.

[0045] In a further aspect, the invention relates to a container containing the pulverulent composition according to the invention. All described preferred embodiments of the composition according to the invention are also considered preferred embodiments for the container according to the invention.

[0046] In a preferred embodiment, the container contains at least 10 mg, preferably at least 50 mg, more preferably at least 200 mg, even more preferably at least 400 mg, most preferably at least 800 mg of the pulverulent composition. Particularly preferably, the container contains between 10 mg and 20,000 mg, more preferably between 50 mg and 10,000 mg, more preferably between 200 mg and 5,000 mg, even more preferably between 400 mg and 2,500 mg, most preferably between 800 mg and 1,250 mg of the pulverulent composition. In the context of the invention, it has been found that this amount is particularly suitable for a single application or for several successive applications. The container thus preferably contains a pre-portioned amount of the composition according to the invention for one application and can be easily disposed of after consumption. This ensures that the user consumes an optimal amount of the composition without having to ensure this amount by weighing or the like.

[0047] Any type of container may be used within the scope of the invention. Preferably, it is a sachet, a can, an ampoule, a jar or a bottle. In particular, sachets have proven to be particularly practical, as they can be easily transported and can be easily disposed of after consumption of the composition contained therein.

[0048] In another aspect, the invention relates to a kit containing a pulverulent composition according to the invention and a nasal applicator such as a snuffer or a snuff tube. Preferably, the kit contains a container according to the invention and a nasal applicator such as a snuff spoon or a snuff tube. All described preferred embodiments of the composition according to the invention and of the container according to the invention are also considered preferred embodiments for the kit according to the invention.

[0049] A snuff tube, often also referred to as a nasal tube or draw tube, is an object that facilitates the nasal consumption of pulverulent compositions. The snuff tube can be placed at the nostril and the composition can be drawn into the nose by vigorous intermittent inhalation through the snuff tube. Preferably, the snuff tube is tubular or channel shaped.

[0050] Another nasal applicator is the snuffera spoon shaped object which facilitates the nasal application of pulverulent compositions. In addition, the snuffer allows a dose of the pulverulent composition to be removed from the container for nasal application.

[0051] In a preferred embodiment, the kit contains at least two, preferably at least three, in particular at least five containers according to the invention. Each of these containers may in turn contain a pre-portioned amount of the composition according to the invention, so that the consumer can consume an optimal amount of the composition for each application without having to weigh it out.

[0052] In another aspect, the present invention relates to a use of a pulverulent composition, a container, or a kit according to the invention for nasal application of the pulverulent composition. The application may be carried out, for example, by drawing into the nose the composition distributed on a surface, directly from the container according to the invention (for example from a can), and/or via a nasal applicator such as a snuffer or a snuff tube.

[0053] Preferably, the use is for nasal application of the pulverulent composition to a human. The use is therefore preferably by a human being. Preferably, the human is a neurologically and psychiatrically healthy person or a person who has no neurological and/or psychiatric disorders. In particular, the person is a healthy individual.

[0054] In a preferred embodiment, the use of the nasal application comprises at least 10 mg, preferably at least 50 mg, more preferably at least 200 mg, even more preferably at least 400 mg, most at least 800 mg of the pulverulent composition. In preferably particular, it is preferred that the use of the nasal application comprises between 10 mg and 5,000 mg, preferably between 50 mg and 4,000 mg, more preferably between 200 mg and 3,000 mg, even more preferably between 400 mg and 2,000 mg, most preferably between 800 mg and 1,250 mg of the pulverulent composition. These amounts have been found to be particularly favourable for a single application, or for several successive applications.

[0055] In further aspects, which will be described in greater detail below, the invention relates to a number of different uses of pulverulent compositions, wherein the pulverulent composition is applied nasally. In the context of all the described uses, the pulverulent composition is preferably a pulverulent composition according to the invention as described herein. For all described uses, the container according to the invention or the kit according to the invention (each containing the pulverulent composition according to the invention) may also be used instead of the pulverulent composition. All described preferred embodiments of the composition according to the invention, the container according to the invention, the kit according to the invention and the individual uses according to the invention are also considered preferred embodiments for all uses disclosed herein.

[0056] In the uses specified herein, the daily dose of the pulverulent composition is preferably between 10 mg and 20,000 mg, more preferably between 50 mg and 10,000 mg, more preferably between 200 mg and 5,000 mg, even more preferably between 400 mg and 2,500 mg, most preferably between 800 mg and 1,250 mg. This daily dose may be administered in one or more applications, for example in 10 applications with a dose of 100 mg each.

[0057] One aspect of the invention relates to the use of a pulverulent composition containing taurine, caffeine, L-arginine and L-tryptophan for improving cognitive performance, in particular for increasing concentration and/or neural efficiency, wherein the pulverulent composition is applied nasally.

[0058] Especially with regard to the ability to concentrate, it has been shown that the presence of arginine in the composition leads to a particularly strong effect, including a surprising prolongation of the effect. Furthermore, it has been shown that nasal administration is superior to intake via food, for example as a drink.

[0059] The phenomenon of so-called neural efficiency is described for example in Grabner, et al. (When intelligence loses its impact: Neural efficiency during reasoning in a familiar area. International Journal of Psychophysiology 49.2 (2003): 89-98), Neubauer and Fink (Intelligence and neural efficiency. Neuroscience & Biobehavioral Reviews 33.7 (2009): 1004-1023) and Dunst, et al (Neural efficiency as a function of task demands. Intelligence 42 (2014): 22-30). Electron-encephalogram (EEG) imaging techniques have shown that intelligent people are able to limit brain activation to smaller areas of the cerebral cortex, primarily those that are truly necessary for processing the task at hand. Less gifted people, on the other hand, have to activate larger parts of their brain and thus consume more resources for the same task. Neural efficiency is a measure of these psychophysiological differences that occur in the thought processes of intelligent and less intelligent people. The phenomenon of selective activation of areas of the brain that occurs in particularly intelligent people is also called the genius effect.

[0060] It was already known from WO 2006/084894 A1 that the oral administration of tryptophan together with caffeine and taurine can lead to an increase in neural efficiency and to an improvement in cognitive performance. In the context of the present invention, it has been found that, on the one hand, the additional combination with arginine and, on the other hand, a nasal administration enable an improvement of these effects.

[0061] After administration of the composition according to the invention, the areas of the brain required for the performance of a specific cognitive and concentrative task are activated in a more targeted manner. In particular, the increase in activity is centred on those areas of the cerebral cortices which are required to cope with a particular cognitive task. Another particular advantage is that the recovery process following stress leads to a more reduced level, i.e. the recovery period is shortened. The composition according to the invention thus leads to the genius effect, i.e. a brain activity of high neural efficiency, which otherwise only occurs in particularly intelligent people. This effect is even better than the administered known from orally compositions WO 2006/084894 A1 with regard to the strength and course (onset and duration) of the effect.

[0062] Another aspect of the invention relates to the use of a pulverulent composition containing taurine, caffeine, L-arginine and L-tryptophan for preventing over-activation of areas of the brain during stress and/or for improving down-regulation after stress, wherein the pulverulent composition is applied nasally. The composition according to the invention can attenuate exaggerated stress responses whilst, however, preserving the hormonal responses necessary to mobilise ergotropic resources. The down-regulation of central nervous activation can be accelerated.

[0063] In the context of the invention, it has been shown that the composition according to the invention, in particular due to the presence of L-arginine and the nasal application, has particularly beneficial effects on physical performance. In particular, a strong, rapid-onset and long-lasting effect is made possible. A further aspect of the invention therefore relates to the use of a pulverulent caffeine, L-arginine and composition containing taurine, L-tryptophan for improving physical performance, in particular for increasing strength and/or endurance, wherein the pulverulent composition is applied nasally.

[0064] Furthermore, the composition according to the invention can lead to a serotonin release and mood enhancement, as well as to a stimulation of brain activity in a healthy person. Another aspect of the invention therefore relates to the use of a pulverulent composition containing taurine, caffeine, L-arginine and L-tryptophan for mood enhancement, wherein the pulverulent composition is applied nasally. The invention additionally relates to the use of a pulverulent composition containing taurine, caffeine, L-arginine and L-tryptophan for stimulating brain activity, wherein the pulverulent composition is applied nasally.

[0065] Surprisingly, it has been shown that the pulverulent composition according to the invention can be used particularly advantageously as a flavouring. After nasal administration, on the one hand the composition itself leads to a positive flavour experience, and on the other hand the composition also acts as a flavour catalyst for other flavourings. Thus, after consumption of the composition according to the invention, other flavourings are perceived more intensely. The effect of, for example, a room aroma or another administered aroma/flavouring is thereby enhanced. Without being bound to a specific theory, it is suspected that the nasal application enables a direct effect of the composition on the olfactory epithelium in the nasal cavity.

[0066] Another aspect of the invention therefore relates to the use of a pulverulent composition containing taurine, caffeine, L-arginine and L-tryptophan as a flavouring, wherein the pulverulent composition is applied nasally.

[0067] The invention therefore further relates to the use of a pulverulent composition containing taurine, caffeine, L-arginine and L-tryptophan for enhancing the effect of flavourings, wherein the pulverulent composition is applied nasally. The use preferably comprises the administration of at least one further flavouring. The further flavouring may also be applied nasally, for example as a powder, as a liquid, or as an aerosol, or may also be administered via the room air, for example via a diffuser or a scented candle. The further flavouring is preferably a synthetic or natural flavouring agent, for example vanillin or menthol, or a flavour extract, in particular from fruits, spices, or herbs, or an essential oil. Advantageously, the use can also take place before the ingestion of food and/or beverages, for example in restaurants or bars, whereby the taste experience is intensified.

[0068] All parameters mentioned herein, unless otherwise indicated, refer to SATP conditions according to IUPAC (Standard Ambient Temperature and Pressure), in particular to a temperature of 25? C. and a pressure of 101,300 Pa. All percentages (%) herein are by weight unless otherwise indicated.
