Definitions

  • the present invention relates to substances for inducing and intensifying the tanning mechanisms of the skin and to cosmetic or dermatological formulations containing the same.
  • tanning with ultraviolet radiation can result in considerable damage to the skin if the effect is too long or a certain dose is exceeded.
  • ⁇ 3rd degree cell damage occur on deep cell damage, the body reacts with fever, the epidermis are shed over a large area.
  • the 2nd and 3rd degrees are also called solar dermatitis.
  • the formation of the erythema depends on the wavelength.
  • the erythema range of the UV-B is between 280 nm and 320 nm.
  • UV-A rays with a wavelength between 320 nm and 400 nm.
  • UV-B radiation varies greatly depending on numerous factors (e.g. annual and Time of day or latitude)
  • the UV-A radiation remains relatively constant day by day, irrespective of the time of year, time of day or geographical factors.
  • the major part of UV-A radiation penetrates into the living epidermis, while about 70% of UV-B rays are retained by the homolayer.
  • UV-A radiation has only a negligible biological effect and that UV-B rays are accordingly responsible for most of the light damage to human skin.
  • UV-B radiation is far more dangerous than UV-B radiation in terms of triggering photodynamic, especially phototoxic reactions and chronic changes in the skin.
  • the damaging influence of UV-B radiation can also be intensified by UV-A radiation.
  • UV-A radiation with high irradiance.
  • the UV-A irradiance generated is usually a factor of 3 to 5 higher, in some cases even up to a factor of 10.
  • a small proportion of UV-B rays are emitted.
  • the radiation spectrum is therefore in usually cheaper in terms of tanning and less worrying about the sunburn risk than the natural spectrum of the sun.
  • make-up or make-up preparations The easiest way to give your skin a brown hue is to apply appropriately colored make-up or make-up preparations. However, only those parts of the body that are covered by the colored preparations are of course stained. A disadvantage of the make-up is therefore the time-consuming procedure of applying. Another disadvantage is that they rub off heavily on textiles such as shirt collars or blouses. In addition, the different dyes can have different allergenic potency and can even be irritating to the skin.
  • a further possibility for artificial tanning is to apply substances to the skin which undergo a chemical color reaction with the hom layer, which results in an artificial tanning of the uppermost layers of the skin.
  • the most important and still the most frequently used active ingredient in self-tanning preparations is dihydroxyacetone (DHA), a trivalent sugar found in the human body. DHA reacts with the proteins and amino acids of the homolayer, whereby the color tone is via a The resulting color and the intensity of the discoloration depend on the type of amino compounds and are also influenced, for example, by the preparation and the thickness of the hom layer.
  • DHA dihydroxyacetone
  • This type of tanning is a purely chemical reaction of the hom layer. Although this achieves a certain cosmetic result, the tan does quite well quickly and is without any protective function for the skin. This tanning is completely independent of the melanocytes of the skin, which bring about the natural tanning of the skin through the pigment melanin they form.
  • Another type of artificial tanning which is also completely independent of UV light, can be brought about by the hormones, which are also released in the body as a result of (natural) UV radiation and ultimately stimulate the melanocytes to synthesize melanin.
  • proopiomelanocortin POMC
  • aMSH proopiomelanocortin
  • synthetic variants such as NDP
  • these hormones can generally bring about a tan, their use in cosmetics is forbidden, since they are clearly pharmacologically active substances (hormones) that should not be used widely without medical indication.
  • the object of the present invention was therefore to avoid the disadvantages of the prior art and to find substances for tanning the skin, the use of which gives the skin a tanned appearance even without the action of sun rays and which intensify the existing natural tanning of the skin and the let natural skin tanning last longer.
  • these substances should be harmless to health, non-irritating and easy to handle and the resulting shade should correspond to the natural healthy skin color.
  • the tan obtained should be lightfast and not washable.
  • Another object of the present invention was to find cosmetic or dermatological preparations for tanning the skin. It was surprising and the solution to these problems is that the disadvantages of the prior art are remedied by the use of one or more substances, which are selected from the group of AGEs and / or their precursors, for tanning the skin.
  • AGE comes from the English term "Advanced Glycosylation Endproducts”. AGEs in the sense of the present invention can be obtained, for example, according to the following (exemplary) reaction equation:
  • Advantageous starting materials (I) carry an aldehyde group (CHO) and are selected, for example, from the group of the sugars (aldoses, eg triosen, tetrosen, pentoses, hexoses and the like such as glucose, galactose, mannose etc.).
  • aldehyde group CHO
  • sugars aldoses, eg triosen, tetrosen, pentoses, hexoses and the like such as glucose, galactose, mannose etc.
  • Advantageous starting materials (II) have a free amino group and are selected, for example, from the group of amino acids and the group of peptides with terminal amino groups, in particular lysine, hydroxylysine, arginine, tryptophan and histidine are advantageous.
  • the free amino group can also advantageously come from N-terminal ends of proteins and peptides, furthermore also advantageously Sphingosine and dihydrosphingosine and their homologues with differently long (unsaturated) acyl residues.
  • AGEs according to the invention preferably contain at least one nitrogen-containing five and / or six ring.
  • FFI which is characterized by the following structural formula, is advantageous in the sense of the present invention:
  • AFGP which is characterized by the following structural formula:
  • the radical R originates, for example, from proteins and peptides; accordingly, these are preferably peptide, amino acid or protein residues which can be attached terminally or laterally to the nitrogen atom.
  • R is also advantageously selected, for example, from the group of saturated or unsaturated, branched or unbranched alkyl groups having 1 to 35 carbon atoms.
  • pentosidine which is characterized by the following structural formula:
  • A2E which is characterized by the following structural formula, is also particularly advantageous in the sense of the present invention:
  • the structural formulas shown are of course not intended to limit the invention to certain isomers of the substances according to the invention. Rather, isomers or isomer mixtures not shown are also advantageous for the purposes of the present invention.
  • the tanning substances in the sense of the present invention are distinguished, inter alia, by the fact that, after topical application, they induce the formation of skin's own pigments in the skin, increase the melanin synthesis and in this way produce an increased tanning of the skin. They are harmless to health, non-irritating and easy to use, and the resulting shade naturally corresponds to that of the natural, healthy skin color.
  • the tan obtained is - since it corresponds to the natural tanning - lightfast and not washable.
  • the substances according to the invention also surprisingly intensify the tanning of already tanned skin and furthermore delay the bleaching of tanned skin.
  • Another advantage of the present invention results from the protective properties of natural melanin formed in the skin.
  • these functions of melanin are also very important for the skin, i.a. regarding homeostasis, skin aging prevention and the like:
  • Melanin acts as a natural UV filter to protect against damaging UV rays and also as an antioxidant to protect against reactive oxygen species (oxidative stress), which can occur due to sun exposure, among other things.
  • the substances according to the invention are particularly suitable as tanning agents in cosmetic or dermatological preparations.
  • the present invention therefore also relates to cosmetic or dermatological formulations, characterized in that they contain at least one substance which is selected from the group of AGEs and / or their precursors.

  • the formulations according to the invention are extremely satisfactory preparations which are distinguished by a uniform coloring effect. It was not foreseeable for the person skilled in the art that the formulations according to the invention would be easier to formulate, give the skin a naturally tanned appearance faster and better, make the skin tan last longer, work better than moisturizing preparations, better promote smoothing of the skin distinguish better care effect, ⁇ have better sensory properties, such as, for example, the spreadability on the skin or the ability to be drawn into the skin, and ⁇ would offer better / risk-free protection of the skin (against UV radiation) than the preparations of the prior art.

Substanzen zur Induktion und Intensivierung der Bräunungsmechanismen der Haut und kosmetische oder dermatologische Formulierungen dieselben enthaltendContaining substances for inducing and intensifying the tanning mechanisms of the skin and cosmetic or dermatological formulations
Die vorliegende Erfindung betrifft Substanzen zur Induktion und Intensivierung der Bräunungsmechanismen der Haut und kosmetische oder dermatologische Formulierungen dieselben enthaltend.The present invention relates to substances for inducing and intensifying the tanning mechanisms of the skin and to cosmetic or dermatological formulations containing the same.
Unter künstlicher Bräunung sind alle Maßnahmen zu verstehen, die der Haut ohne Einwirkung von Sonnenstrahlen ein gebräuntes Aussehen verleihen. Dazu sind verschiedene Möglichkeiten prinzipiell denkbar, wie beispielsweiseArtificial tanning means all measures that give the skin a tanned appearance without the action of the sun's rays. In principle, various options are conceivable, for example
■ physikalische Anfärbung durch Anwendung von Schminken oder Make-up,■ physical staining by applying make-up or make-up,
■ Anfärbung durch chemische Reaktionen mit Hilfe von selbstbräunenden Zubereitungen,Staining by chemical reactions with the help of self-tanning preparations,
■ Bräunung durch (orale) Einnahme von Carotinoiden sowie■ Tanning through (oral) ingestion of carotenoids as well
■ künstliche Bestrahlung unter Verwendung technisch hergestellter Lichtquellen.■ Artificial radiation using technically manufactured light sources.
Dabei ist zu beachten, daß es bei der Bräunung mit ultravioletter Strahlung, wie sie im natürlichen Sonnenspektrum vorkommt oder von künstlichen Lichtquellen erzeugt wird, bei zu langer Einwirkung oder Überschreitung einer bestimmten Dosis zu nicht unerheblichen Hautschäden kommen kann.It should be noted that tanning with ultraviolet radiation, such as that which occurs in the natural sun spectrum or is generated by artificial light sources, can result in considerable damage to the skin if the effect is too long or a certain dose is exceeded.
Setzt man die Haut zu lange der Sonne oder einer künstlichen Strahlenquelle aus, so entwickelt sich nach einer Latenzzeit von 2 bis 3 Stunden eine gegen die unbestrahlte Haut stark abgegrenzte Hautrötung, das Erythema solare. Bei dem so entstehenden Sonnenbrand unterscheidet man zwischenIf you expose the skin to the sun or an artificial source of radiation for too long, after a latency period of 2 to 3 hours a reddening of the skin against the unexposed skin develops, the erythema solar. With the resulting sunburn, one differentiates between
■ 1. Grad: Erythem (Rötung, Wärmegefühl) klingt nach 2 bis 3 Tagen wieder ab und verschwindet unter gleichzeitig zunehmender Pigmentierung, t ■ 1st degree: erythema (reddening, feeling of warmth) subsides after 2 to 3 days and disappears with increasing pigmentation, t
■ 2. Grad: Blasenbildung auf der Haut bilden sich Blasen mit Brennen und Jucken, die Oberhaut wird flächig abgestoßen,■ 2nd degree: blisters form on the skin, blisters with burning and itching, the epidermis is pushed off flatly,
■ 3. Grad: Zellschädigung es treten tiefgehende Zellschädigungen auf, der Körper reagiert mit Fieber, die Oberhaut wird großflächig abgestoßen. Der 2. und 3. Grad werden auch als Dermatitis solare bezeichnet. ■ 3rd degree: cell damage occur on deep cell damage, the body reacts with fever, the epidermis are shed over a large area. The 2nd and 3rd degrees are also called solar dermatitis.
Die Bildung des Erythems ist abhängig von der Wellenlänge. Der Erythembereich des UV-B liegt zwischen 280 nm und 320 nm.The formation of the erythema depends on the wavelength. The erythema range of the UV-B is between 280 nm and 320 nm.
Etwa 90 % der auf die Erde gelangenden ultravioletten Strahlung bestehen allerdings aus UV-A-Strahlen mit einer Wellenlänge zwischen 320 nm und 400 nm. Während die UV-B-Strahlung in Abhängigkeit von zahlreichen Faktoren stark variiert (z. B. Jahres- und Tageszeit oder Breitengrad), bleibt die UV-A-Strahlung unabhängig von Jahres- und tageszeitlichen oder geographischen Faktoren Tag für Tag relativ konstant. Gleichzeitig dringt der überwiegende Teil der UV-A-Strahlung jn die lebende Epidermis ein, während etwa 70 % der UV-B-Strahlen von der Homschicht zurückgehalten werden.However, about 90% of the ultraviolet radiation reaching the earth consists of UV-A rays with a wavelength between 320 nm and 400 nm. While the UV-B radiation varies greatly depending on numerous factors (e.g. annual and Time of day or latitude), the UV-A radiation remains relatively constant day by day, irrespective of the time of year, time of day or geographical factors. At the same time, the major part of UV-A radiation penetrates into the living epidermis, while about 70% of UV-B rays are retained by the homolayer.
Man hat lange Zeit fälschlicherweise angenommen, daß die langwellige UV-A-Strahlung nur eine vernachlässigbare biologische Wirkung aufweist und daß dementsprechend die UV-B-Strahlen für die meisten Lichtschäden an der menschlichen Haut verantwortlich seien. Inzwischen ist allerdings durch zahlreiche Studien belegt, daß UV-A-Strahlung im Hinblick auf die Auslösung photodynamischer, speziell phototoxischer Reaktionen und chronischer Veränderungen der Haut weitaus gefährlicher als UV-B-Strahlung ist. Auch kann der schädigende Einfluß der UV-B-Strahlung durch UV-A-Strahlung noch verstärkt werden.It has long been erroneously assumed that long-wave UV-A radiation has only a negligible biological effect and that UV-B rays are accordingly responsible for most of the light damage to human skin. In the meantime, however, numerous studies have shown that UV-A radiation is far more dangerous than UV-B radiation in terms of triggering photodynamic, especially phototoxic reactions and chronic changes in the skin. The damaging influence of UV-B radiation can also be intensified by UV-A radiation.
Moderne Bräunungsanlagen, wie sie beispielsweise in Solarien verwendet werden, produzieren überwiegend UV-A-Strahlung in hoher Bestrahlungsstärke. Verglichen mit der natürlichen Mittagssonne im Sommer liegt die erzeugte UV-A-Bestrahlungsstärke in der Regel um den Faktor 3 bis 5 höher, in Einzelfällen sogar bis zum Faktor 10. Gleichzeitig wird ein geringer Anteil an UV-B-Strahlen ausgesandt. Das Strahlenspektrum ist daher in der Regel in bezug auf die Bräunung günstiger und hinsichtlich des Sonnenbrandrisikos weniger bedenklich als das natürliche Sonnenspektrum.Modern tanning systems, such as those used in solariums, mainly produce UV-A radiation with high irradiance. Compared to the natural midday sun in summer, the UV-A irradiance generated is usually a factor of 3 to 5 higher, in some cases even up to a factor of 10. At the same time, a small proportion of UV-B rays are emitted. The radiation spectrum is therefore in usually cheaper in terms of tanning and less worrying about the sunburn risk than the natural spectrum of the sun.
Der entscheidende Vorteil von Solarien ist die Möglichkeit, eine genaue und begrenzte Bestrahlungsdosis bei definierter Strahlenqualität anzuwenden, was unter natürlichen Bedingungen kaum gegeben ist. Selbstverständlich ist aber insbesondere infolge der erhöhten UV-A-Bestrahlungsstärke ein gewisses Risiko nicht auszuschließen.The decisive advantage of solariums is the possibility to use an exact and limited radiation dose with a defined radiation quality, which is hardly possible under natural conditions. Of course, a certain risk cannot be ruled out, particularly as a result of the increased UV-A irradiance.
Dementsprechend sollte, wer lichtbedingte Hautschäden wie Sonnenbrand, chronische Lichtschäden oder ein mögliches Karzinomrisiko vermeiden will, aber andererseits auf die modisch erwünschte Bräune nicht verzichten möchte, auf solche Methoden der Bräunung zurückgreifen, die ohne die Anwendung künstlich erzeugter oder natürlicher ultravioletter Strahlen auskommen.Accordingly, if you want to avoid light-related skin damage such as sunburn, chronic light damage or a possible carcinoma risk, but on the other hand do not want to do without the fashionably desired tan, you should resort to methods of tanning that do without the use of artificially produced or natural ultraviolet rays.
Die einfachste Art und Weise, seiner Haut einen braunen Farbton zu verleihen, ist das Auftragen entsprechend gefärbter Schminken oder Make-up-Präparate. Allerdings werden selbstverständlich nur solche Körperpartien angefärbt, die von den farbigen Präparaten überdeckt werden. Ein Nachteil der Schminken ist deshalb die zeitraubende Prozedur des Auftragens. Ferner nachteilig ist, daß sie stark auf Textilien wie Hemdkragen oder Blusen abfärben. Darüber hinaus können die verschiedenen Farbstoffe unterschiedliche allergene Potenz aufweisen und sogar hautirritierend wirken.The easiest way to give your skin a brown hue is to apply appropriately colored make-up or make-up preparations. However, only those parts of the body that are covered by the colored preparations are of course stained. A disadvantage of the make-up is therefore the time-consuming procedure of applying. Another disadvantage is that they rub off heavily on textiles such as shirt collars or blouses. In addition, the different dyes can have different allergenic potency and can even be irritating to the skin.
Eine weitere Möglichkeit zur künstlichen Bräunung ist, Substanzen auf die Haut aufzutragen, die mit der Homschicht eine chemische Farbreaktion eingehen, wobei es zu einer artifiziellen Bräunung der obersten Hautschichten kommt. Der wichtigste und nach wie vor am häufigsten eingesetzte Wirkstoff in selbstbräunenden Zubereitungen (sog. „Selbstbräunern") ist das Dihydroxyaceton (DHA), ein im menschlichen Körper vorkommender dreiwertiger Zucker. DHA reagiert mit den Proteinen und Aminosäuren der Homschicht, wobei der Farbton über eine Polymerisation zustande kommt. Der entste- hende Farbton sowie die Intensität der Verfärbung sind von der Art der Aminoverbin- dungen abhängig und werden beispielsweise auch durch die Zubereitung und die Dicke der Homschicht beeinflußt.A further possibility for artificial tanning is to apply substances to the skin which undergo a chemical color reaction with the hom layer, which results in an artificial tanning of the uppermost layers of the skin. The most important and still the most frequently used active ingredient in self-tanning preparations (so-called "self-tanning agents") is dihydroxyacetone (DHA), a trivalent sugar found in the human body. DHA reacts with the proteins and amino acids of the homolayer, whereby the color tone is via a The resulting color and the intensity of the discoloration depend on the type of amino compounds and are also influenced, for example, by the preparation and the thickness of the hom layer.
Diese Art der Bräunung ist eine rein chemische Reaktion der Homschicht. Hierdurch wird zwar ein gewisses kosmetisches Ergebnis erreicht, jedoch schilfert die Bräune recht schnell wieder ab und ist ohne jede Schutzfunktion für die Haut. Diese Bräunung ist völlig unabhängig von den Melanozyten der Haut, die die natürliche Hautbräunung durch das von ihnen gebildete Pigment Melanin herbeiführen.This type of tanning is a purely chemical reaction of the hom layer. Although this achieves a certain cosmetic result, the tan does quite well quickly and is without any protective function for the skin. This tanning is completely independent of the melanocytes of the skin, which bring about the natural tanning of the skin through the pigment melanin they form.
Die Anfärbung durch Selbstbräuner erfolgt ohne Sonnenlichteinwirkung. Im Gegensatz dazu werden auch sogenannte Pre-Tan-Produkte oder Tan-Promoter angeboten, die vor der Sonnenbestrahlung aufgetragen werden müssen. In der Sonne tritt dann eine Vergilbung dieser Zubereitungen ein, die zu einer leichten Braungelb-Färbung der Oberhaut führen soll, welche die „Sonnenbräune" zusätzlich verstärkt.Staining by self-tanners takes place without exposure to sunlight. In contrast, so-called pre-tan products or tan promoters are also offered, which must be applied before the sun is shined. These preparations then turn yellow in the sun, which is said to lead to a slight brown-yellow coloring of the epidermis, which additionally reinforces the "tan".
Eine weitere, von UV-Licht ebenfalls völlig unabhängige Art der künstlichen Bräunung kann durch die Hormone herbeigeführt werden, die im Körper auch infolge (natürlicher) UV-Bestrahlung üblicherweise freigesetzt werden und die Melanozyten letztlich zur Melanin-Synthese anregen. Zu nennen wären in diesem Zusammenhang beispielsweise Abkömmlinge von Proopiomelanocortin (POMC) wie aMSH und synthetische Varianten (wie NDP), die zum Teil weitaus höhere Aktivität als das natürliche aMSH aufweisen. Zwar kann durch diese Hormone grundsätzlich eine Bräunung herbeigeführt werden, jedoch verbietet sich ihr Einsatz in Kosmetika, da es sich eindeutig um pharmakologisch wirkende Substanzen (Hormone) handelt, welche nicht ohne medizinische Indikation breit eingesetzt werden sollten.Another type of artificial tanning, which is also completely independent of UV light, can be brought about by the hormones, which are also released in the body as a result of (natural) UV radiation and ultimately stimulate the melanocytes to synthesize melanin. In this context, descendants of proopiomelanocortin (POMC) such as aMSH and synthetic variants (such as NDP) may be mentioned, some of which have much higher activity than natural aMSH. Although these hormones can generally bring about a tan, their use in cosmetics is forbidden, since they are clearly pharmacologically active substances (hormones) that should not be used widely without medical indication.
Aufgabe der vorliegenden Erfindung war es also, die Nachteile des Standes der Technik zu vermeiden und Substanzen zur Bräunung der Haut finden, durch deren Anwendung der Haut auch ohne Einwirkung von Sonnenstrahlen ein gebräuntes Aussehen verliehen wird und welche die vorhandene natürliche Bräunung der Haut intensivieren und die natürliche Hautbräunung länger anhalten lassen.The object of the present invention was therefore to avoid the disadvantages of the prior art and to find substances for tanning the skin, the use of which gives the skin a tanned appearance even without the action of sun rays and which intensify the existing natural tanning of the skin and the let natural skin tanning last longer.
Insbesondere sollten diese Substanzen gesundheitlich unbedenklich, nicht reizend und leicht zu handhaben sein und der resultierende Farbton der natürlichen gesunden Hautfarbe entsprechen. Die erhaltene Bräunung sollte lichtecht und nicht abwaschbar sein.In particular, these substances should be harmless to health, non-irritating and easy to handle and the resulting shade should correspond to the natural healthy skin color. The tan obtained should be lightfast and not washable.
Eine weitere Aufgabe der vorliegenden Erfindung war es, kosmetische oder dermatologische Zubereitungen zur Bräunung der Haut zu finden. Es war überraschend und darin liegt die Lösung dieser Aufgaben, daß den Nachteilen des Standes der Technik abgeholfen wird durch die Verwendung einer oder mehrerer Substanzen, welche gewählt werden aus der Gruppe der AGEs und/oder deren Vorläufern, zur Bräunung der Haut.Another object of the present invention was to find cosmetic or dermatological preparations for tanning the skin. It was surprising and the solution to these problems is that the disadvantages of the prior art are remedied by the use of one or more substances, which are selected from the group of AGEs and / or their precursors, for tanning the skin.
Die Bezeichnung AGE kommt vom englischen Begriff „Advanced Glycosylation Endproducts". AGEs im Sinne der vorliegenden Erfindung sind beispielsweise erhältlich gemäß der folgenden (beispielhaften) Reaktionsgleichung:The term AGE comes from the English term "Advanced Glycosylation Endproducts". AGEs in the sense of the present invention can be obtained, for example, according to the following (exemplary) reaction equation:
(0 00 (Hl) (IV)(0 00 (Hl) (IV)
Vorteilhaft im Sinne der vorliegenden Erfindung sind neben den eigentlichen AGEs auch deren Vorläufer, wie z. B. Amadori- oder Maillard-Produkte (entsprechend (III) in obiger Reaktionsgleichung) bzw. sogenannte EGEs (Early Glycosylation Endproducts), welche beispielsweise als Zwischenprodukte bei der Umlagerung von den Amadoriprodukten (III) zu den AGEs (IV) erhältlich sind.In addition to the actual AGEs, their precursors, such as e.g. B. Amadori or Maillard products (corresponding to (III) in the above reaction equation) or so-called EGEs (early glycosylation end products), which are available, for example, as intermediates in the rearrangement of the Amadori products (III) to the AGEs (IV).
Vorteilhafte Ausgangsstoffe (I) tragen eine Aldehydgruppe (CHO) und werden beispiels- weise aus der Gruppe der Zucker (Aldosen, z. B. Triosen, Tetrosen, Pentosen, Hexosen und dergleichen wie Glucose, Galactose, Mannose usw.) gewählt.Advantageous starting materials (I) carry an aldehyde group (CHO) and are selected, for example, from the group of the sugars (aldoses, eg triosen, tetrosen, pentoses, hexoses and the like such as glucose, galactose, mannose etc.).
Vorteilhafte Ausgangsstoffe (II) weisen eine freie Aminogruppe auf und werden beispielsweise aus der Gruppe der Aminosäuren und der Gruppe der Peptide mit endständigen Aminogruppen gewählt, insbesondere Lysin, Hydroxylysin, Arginin, Tryptophan und Histidin sind vorteilhaft. Ferner vorteilhaft die kann die freie Aminogruppe auch aus N- terminalen Enden von Proteinen und Peptiden stammen, ferner auch vorteilhaft Sphingosin sowie Dihydrosphingosin und deren Homologen mit verschieden langen (ungesättigten) Acylresten.Advantageous starting materials (II) have a free amino group and are selected, for example, from the group of amino acids and the group of peptides with terminal amino groups, in particular lysine, hydroxylysine, arginine, tryptophan and histidine are advantageous. Furthermore, the free amino group can also advantageously come from N-terminal ends of proteins and peptides, furthermore also advantageously Sphingosine and dihydrosphingosine and their homologues with differently long (unsaturated) acyl residues.
Bevorzugt enthalten erfindungsgemäße AGEs mindestens einen stickstoffhaltigen Fünf- und/oder Sechsring.AGEs according to the invention preferably contain at least one nitrogen-containing five and / or six ring.
Vorteilhaft im Sinne der vorliegenden Erfindung ist beispielsweise das sogenannte FFI, welches sich durch die folgende Strukturformel auszeichnet:The so-called FFI, which is characterized by the following structural formula, is advantageous in the sense of the present invention:
Ferner vorteilhaft im Sinne der vorliegenden Erfindung ist das sogenannte AFGP, welches sich durch die folgende Strukturformel auszeichnet: Also advantageous in the sense of the present invention is the so-called AFGP, which is characterized by the following structural formula:
Ferner vorteilhaft im Sinne der vorliegenden Erfindung sind Pyrraline, welche sich durch die folgende Strukturformel auszeichnen:Also advantageous in the sense of the present invention are pyrralines which are distinguished by the following structural formula:
Erfindungsgemäß vorteilhaft stammt der Rest R beispielsweise aus Proteinen und Pep- tiden; dementsprechend handelt es sich hierbei vorzugsweise um Peptid-, Aminosäureoder Proteinreste, welche terminal oder seitlich an das Stickstoffatom angebunden sein können. R wird ferner vorteilhaft beispielsweise aus der Gruppe der gesättigten oder ungesättigten, verzweigten oder unverzweigten Alkylgruppen mit 1 bis 35 Kohlenstoffatomen gewählt.Advantageously according to the invention, the radical R originates, for example, from proteins and peptides; accordingly, these are preferably peptide, amino acid or protein residues which can be attached terminally or laterally to the nitrogen atom. R is also advantageously selected, for example, from the group of saturated or unsaturated, branched or unbranched alkyl groups having 1 to 35 carbon atoms.
Ferner vorteilhaft im Sinne der vorliegenden Erfindung ist Pentosidin, welches sich durch die folgende Strukturformel auszeichnet:Also advantageous in the sense of the present invention is pentosidine, which is characterized by the following structural formula:
Besonders vorteilhaft im Sinne der vorliegenden Erfindung ist ferner das sogenannte A2E, welches sich durch die folgende Strukturformel auszeichnet:The so-called A2E, which is characterized by the following structural formula, is also particularly advantageous in the sense of the present invention:
Die dargestellten Strukturformeln sollen die Erfindung selbstverständlich nicht auf bestimmte Isomeren der erfindungsgemäßen Substanzen beschränken. Vielmehr sind auch nicht dargestellte Isomere bzw. Isomerengemische vorteilhaft im Sinne der vorliegenden Erfindung. Die bräunenden Substanzen im Sinne der vorliegenden Erfindung zeichnen sich u.a. dadurch aus, daß sie - nach topischer Applikation - in der Haut die Bildung von hauteigenen Pigmenten induzieren, die Melaninsynthese steigern und auf diese Weise eine verstärkte Bräunung der Haut erzeugen. Sie sind gesundheitlich unbedenklich, nicht reizend und leicht zu handhaben, und der resultierende Farbton entspricht naturgemäß dem der natürlichen gesunden Hautfarbe. Die erhaltene Bräunung ist - da sie der natürlichen Bräunung entspricht - lichtecht und nicht abwaschbar. Durch die erfindungsgemäßen Substanzen wird ferner überraschend die Bräunung bereits gebräunter Haut verstärkt und darüber hinaus das Bleichwerden gebräunter Haut verzögert.The structural formulas shown are of course not intended to limit the invention to certain isomers of the substances according to the invention. Rather, isomers or isomer mixtures not shown are also advantageous for the purposes of the present invention. The tanning substances in the sense of the present invention are distinguished, inter alia, by the fact that, after topical application, they induce the formation of skin's own pigments in the skin, increase the melanin synthesis and in this way produce an increased tanning of the skin. They are harmless to health, non-irritating and easy to use, and the resulting shade naturally corresponds to that of the natural, healthy skin color. The tan obtained is - since it corresponds to the natural tanning - lightfast and not washable. The substances according to the invention also surprisingly intensify the tanning of already tanned skin and furthermore delay the bleaching of tanned skin.
Ein weiterer Vorteil der vorliegenden Erfindung ergibt sich aus den Schutzeigenschaften von in der Haut gebildetem natürlichem Melanin. Neben verschiedenen weiteren Funktionen des hauteigenen Melanins (wie beispielsweise "Entgiftung" bzw. Bindung von toxischen Substanzen und/oder Pharmaka etc.), sind ferner insbesondere diese Funktionenen von Melanin für die Haut sehr wichtig, u.a. in Bezug auf die Homeostase, die Vermeidung der Hautalterung und dergleichen:Another advantage of the present invention results from the protective properties of natural melanin formed in the skin. In addition to various other functions of the skin's own melanin (such as "detoxification" or binding of toxic substances and / or pharmaceuticals etc.), these functions of melanin are also very important for the skin, i.a. regarding homeostasis, skin aging prevention and the like:
Melanin wirkt als natürlicher UV-Filter zum Schutz vor schädigenden UV-Strahlen sowie darüberhinaus als Antioxidanz zum Schutz vor reaktiven Sauerstoffspezies (oxidativem Stress), die unter anderem durch Sonnenbestrahlung auftreten können.Melanin acts as a natural UV filter to protect against damaging UV rays and also as an antioxidant to protect against reactive oxygen species (oxidative stress), which can occur due to sun exposure, among other things.
Somit ergibt sich bei erfindungsgemäßer Verwendung (d. h. nach topischer Applikation des erfindungsgemäßen Wirkstoffs) nicht nur ein kosmetischer Nutzen im Sinne einer verstärkte Bräunung durch die gesteigerte Melanin-Synthese in der Haut sondern auch ein zusätzlicher Nutzen durch die verschiedenen Schutzleistungen von Melanin.Thus, when used according to the invention (i.e. after topical application of the active ingredient according to the invention), there is not only a cosmetic benefit in the sense of increased tanning due to the increased melanin synthesis in the skin, but also an additional benefit due to the various protective benefits of melanin.
Dementsprechend eigenen sich die erfindungsgemäßen Substanzen insbesondere hervorragend als bräunende Wirkstoffe in kosmetischen oder dermatologischen Zubereitungen.Accordingly, the substances according to the invention are particularly suitable as tanning agents in cosmetic or dermatological preparations.
Gegenstand der vorliegenden Erfindung sind daher auch kosmetische oder dermatologische Formulierungen, dadurch gekennzeichnet, daß sie mindestens eine Substanz enthalten, welche gewählt wird aus der Gruppe der AGEs und/oder deren Vorläufern.The present invention therefore also relates to cosmetic or dermatological formulations, characterized in that they contain at least one substance which is selected from the group of AGEs and / or their precursors.
Die erfindungsgemäßen Substanzen und kosmetische oder dermatologische Zubereitungen dieselben enthaltend induzieren in der Haut die Bildung von hauteigenen Pigmenten, intensivieren die vorhandene natürliche und/oder künstliche Bräunung der Haut und lassen die Hautbräunung länger anhalten.The substances according to the invention and cosmetic or dermatological preparations containing them induce the formation of skin's own pigments in the skin, intensify the existing natural and / or artificial tanning of the skin and let the skin tan last longer.
Die erfindungsgemäßen Formulierungen sind in jeglicher Hinsicht überaus befriedigende Präparate, die sich durch eine gleichmäßig färbende Wirkung auszeichnen. Es war für den Fachmann nicht vorauszusehen gewesen, daß die erfindungsgemäßen Formulierungen einfacher zu formulieren sein, ■ der Haut schneller und besser ein natürlich gebräuntes Aussehen verleihen, die Hautbräunuhg länger anhalten lassen, besser als feuchtigkeitsspendende Zubereitungen wirken, besser die Hautglättung fördern, I sich durch bessere Pflegewirkung auszeichnen, ■ bessere sensorische Eigenschaften, wie beispielsweise die Verteilbarkeit auf der Haut oder das Einzugsvermögen in die Haut, aufweisen und ■ einen besseren/risikolosen Eigenschutz der Haut (vor UV-Strahlung) bieten würden als die Zubereitungen des Standes der Technik. Zudem entfalten die erfindungsge- mäßen Formulierungen überraschenderweise keine Hormonwirkungen.In all respects, the formulations according to the invention are extremely satisfactory preparations which are distinguished by a uniform coloring effect. It was not foreseeable for the person skilled in the art that the formulations according to the invention would be easier to formulate, give the skin a naturally tanned appearance faster and better, make the skin tan last longer, work better than moisturizing preparations, better promote smoothing of the skin distinguish better care effect, ■ have better sensory properties, such as, for example, the spreadability on the skin or the ability to be drawn into the skin, and ■ would offer better / risk-free protection of the skin (against UV radiation) than the preparations of the prior art. In addition, the formulations according to the invention surprisingly have no hormone effects.
Kosmetische oder dermatologische Formulierungen im Sinne der vorliegenden Erfindung können bevorzugt neben einer oder mehrerer Ölphasen zusätzlich eine oder mehrere Wasserphasen enthalten und beispielsweise in Form von W/O-, O/W-, W/O/W- oder O/W/O-Emulsionen vorliegen. Solche Emulsionen können vorzugsweise auch eine Mi- kroemulsion, eine Pickering-Emulsion oder eine sprühbare Emulsion sein. Darüber hinaus können die erfindungsgemäßen Formulierungen aber auch vorteilhaft in Form von ölfreien Zubereitungen, wie beispielsweise Gelen, oder als wasserfreie Zubereitungen vorliegen.Cosmetic or dermatological formulations within the meaning of the present invention can preferably contain, in addition to one or more oil phases, one or more water phases and, for example, in the form of W / O-, O / W-, W / O / W- or O / W / O- Emulsions are present. Such emulsions can preferably also be a microemulsion, a Pickering emulsion or a sprayable emulsion. In addition, the formulations according to the invention can also advantageously be in the form of oil-free preparations, such as gels, or as anhydrous preparations.
Vorteilhaft ist es, den Gehalt an einer oder mehreren Substanzen aus der Gruppe der AGEs und/oder deren Vorläufern in der kosmetischen oder dermatologischen Formulierung zwischen 0,0001 und 30 Gew.-%, besonders vorteilhaft zwischen 0,01 und 10 Gew.-%, ganz besonders zwischen 0,1 und 2 Gew.-% zu wählen, jeweils bezogen auf das Gesamtgewicht der Formulierung.It is advantageous if the content of one or more substances from the group of AGEs and / or their precursors in the cosmetic or dermatological formulation is between 0.0001 and 30% by weight, particularly advantageously between 0.01 and 10% by weight , especially between 0.1 and 2% by weight, each based on the total weight of the formulation.
Die erfindungsgemäßen Formulierungen können ferner vorteilhaft auch Dihydroxyaceton oder Nußextrakte enthalten sowie weitere Substanzen, welche die Bräune erhalten oder erzeugen sollen.The formulations according to the invention can furthermore advantageously also contain dihydroxyacetone or nut extracts and other substances which are intended to maintain or produce the tan.
Die erfindungsgemäßen Formulierungen können vorteilhaft, wenngleich nicht zwingend, auch in Kombination mit UV-Strahlung - sei es mit künstlich erzeugten oder natürlichen ultravioletten Strahlen - verwendet werden, beispielsweise um die natürliche Bräunung noch zu steigern oder aber um eine besonders lang anhaltende Bräunung zu erreichen. Hierzu können die erfindungsgemäßen Zubereitungen vorteilhaft z. B. vor, nach oder während der Einwirkung von UV-Strahlen auf die Haut aufgebracht werden, beispielsweise in Form einer Presun-, einer Sonnenschutz- oder einer Aftersunformulierung.The formulations according to the invention can advantageously, although not necessarily, also be used in combination with UV radiation - be it with artificially produced or natural ultraviolet rays - for example to increase natural tanning or to achieve a particularly long-lasting tanning.
