Abstract
Description
Die vorliegende Erfindung betrifft kosmetische und dermatologische Formulierungen, insbesondere kosmetische und dermatologische Lichtschutzformulierungen.The present invention relates to cosmetic and dermatological formulations, in particular cosmetic and dermatological light protection formulations.
Die schädigende Wirkung des ultravioletten Teils der Sonnenstrahlung auf die Haut ist allgemein bekannt. In Abhängigkeit von ihrer jeweiligen Wellenlänge haben die Strahlen verschiedene Wirkungen auf das Organ Haut: Die sogenannte UV-C-Strahlung mit einer Wellenlänge, die kleiner als 290 nm ist, wird von der Ozonschicht in der Erdatmosphäre absorbiert und hat daher keine physiologische Bedeutung. Dagegen verursachen Strahlen im Bereich zwischen 290 nm und 320 nm, dem sogenannten UV-B-Bereich, ein Erythem, einen einfachen Sonnenbrand oder sogar mehr oder weniger starke Verbren nungen. Als ein Maximum der Erythemwirksamkeit des Sonnenlichtes wird der engere Bereich um 308 nm angegeben.The harmful effect of the ultraviolet part of solar radiation on the skin is well known. Depending on their respective wavelength, the rays have different effects on the organ skin: the so-called UV-C radiation with a Wavelength that is less than 290 nm is from the ozone layer in the earth's atmosphere absorbed and therefore has no physiological meaning. Against cause Rays in the range between 290 nm and 320 nm, the so-called UV-B range Erythema, a simple sunburn or even more or less severe burns mentions. As the maximum of the erythema effectiveness of sunlight, the narrower Range given around 308 nm.
Zum Schutz gegen UV-B-Strahlung sind zahlreiche Verbindungen bekannt, bei denen es sich zumeist um Derivate des 3-Benzylidencamphers, der 4-Aminobenzoesäure, der Zimtsäure, der Salicylsäure, des Benzophenons sowie auch des 2-Phenylbenzimidazols handelt.Numerous compounds are known for protecting against UV-B radiation, in which it is usually a derivative of 3-benzylidene camphor, 4-aminobenzoic acid, the Cinnamic acid, salicylic acid, benzophenone and also 2-phenylbenzimidazole acts.
Man hat lange Zeit fälschlicherweise angenommen, daß die langwellige UV-A-Strahlung mit einer Wellenlänge zwischen 320 nm und 400 nm 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 Ver änderungen der Haut weitaus gefährlicher als UV-B-Strahlung ist. Auch kann der schä digende Einfluß der UV-B-Strahlung durch UV-A-Strahlung noch verstärkt werden.It has long been erroneously assumed that long-wave UV-A radiation with a wavelength between 320 nm and 400 nm only a negligible one has biological effect and that accordingly the UV-B rays for the most of the light damage to human skin. Is now however, proven by numerous studies that UV-A radiation with regard to the Triggering of photodynamic, especially phototoxic reactions and chronic ver Skin changes are far more dangerous than UV-B radiation. The schä significant influence of UV-B radiation can be increased by UV-A radiation.
So ist es u. a. erwiesen, daß selbst die UV-A-Strahlung unter ganz normalen Alltags bedingungen ausreicht, um innerhalb kurzer Zeit die Collagen- und Elastinfasern zu schädigen, die für die Struktur und Festigkeit der Haut von wesentlicher Bedeutung sind. Hierdurch kommt es zu chronischen lichtbedingten Hautveränderungen - die Haut "altert" vorzeitig. Zum klinischen Erscheinungsbild der durch Licht gealterten Haut gehö ren beispielsweise Falten und Fältchen sowie ein unregelmäßiges, zerfurchtes Relief. Ferner können die von lichtbedingter Hautalterung betroffenen Partien eine unregel mäßige Pigmentierung aufweisen. Auch die Bildung von braunen Flecken, Keratosen und sogar Karzinomen bzw. malignen Melanomen ist möglich. Eine durch die alltägliche UV-Belastung vorzeitig gealterte Haut zeichnet sich außerdem durch eine geringere Aktivität der Langerhanszellen und eine leichte, chronische Entzündung aus.So it is u. a. proved that even UV-A radiation can be found in normal everyday life conditions are sufficient to quickly remove the collagen and elastin fibers damage that are essential for the structure and firmness of the skin. This leads to chronic light-related skin changes - the skin "ages" prematurely. Clinical appearance of light-aged skin For example, wrinkles and fine lines as well as an irregular, furrowed relief. Furthermore, the areas affected by light-induced skin aging can be irregular have moderate pigmentation. Also the formation of brown spots, keratoses and even cancer or malignant melanoma is possible. One through everyday UV exposure to prematurely aged skin is also characterized by less Langerhans cell activity and a mild, chronic inflammation.
Etwa 90% der auf die Erde gelangenden ultravioletten Strahlung besteht aus UV-A-Strahlen. Während die UV-B-Strahlung in Abhängigkeit von zahlreichen Faktoren stark variiert (z. B. Jahres- und Tageszeit oder Breitengrad), bleibt die UV-A-Strahlung unab hängig von jahres- und tageszeitlichen oder geographischen Faktoren Tag für Tag rela tiv konstant. Gleichzeitig dringt der überwiegende Teil der UV-A-Strahlung in die le bende Epidermis ein, während etwa 70% der UV-B-Strahlen von der Hornschicht zu rückgehalten werden.About 90% of the ultraviolet radiation reaching the earth consists of UV-A rays. While the UV-B radiation is strong depending on numerous factors varies (e.g. time of year and time of day or latitude), the UV-A radiation remains unaffected depending on the seasonal and daily time or geographic factors day by day rela tiv constant. At the same time, the major part of UV-A radiation penetrates into the le Entering epidermis while about 70% of the UV-B rays come from the horny layer be held back.
Vorbeugender Schutz gegen UV-A-Strahlen, beispielsweise durch Auftrag von Licht schutzfiltersubstanzen in Form einer kosmetischen oder dermatologischen Formulierung auf die Haut, ist daher von grundsätzlicher Wichtigkeit.Preventive protection against UV-A rays, for example by applying light protective filter substances in the form of a cosmetic or dermatological formulation on the skin, is therefore of fundamental importance.
Im allgemeinen ist das Lichtabsorptionsverhalten von Lichtschutzfiltersubstanzen sehr gut bekannt und dokumentiert, zumal in den meisten Industrieländern Positivlisten für den Einsatz solcher Substanzen existieren, welche recht strenge Maßstäbe an die Do kumentation anlegen. Für die Dosierung der Substanzen in den fertigen Formulierungen können die Extinktionswerte allenfalls eine Orientierungshilfe bieten, denn durch Wechselwirkungen mit Inhaltsstoffen der Haut oder der Hautoberfläche selbst können Unwägbarkeiten auftreten. Ferner ist in der Regel schwierig vorab abzuschätzen, wie gleichmäßig und in welcher Schichtdicke die Filtersubstanz in und auf der Hornschicht der Haut verteilt ist.In general, the light absorption behavior of light protection filter substances is very high well known and documented, especially in most industrialized countries positive lists for the use of such substances exist, which are very strict standards for Do create documentation. For dosing the substances in the finished formulations the absorbance values can at best provide guidance, because by Interactions with ingredients of the skin or the skin surface itself can Uncertainties arise. Furthermore, it is usually difficult to estimate in advance how uniform and in what layer thickness the filter substance in and on the horny layer the skin is distributed.
Zur Prüfung der UV-A-Schutzleistung wird üblicherweise die IPD-Methode verwendet (IPD ∼ immediate pigment darkening). Hierbei wird - ähnlich der Bestimmung des Licht schutzfaktors - ein Wert ermittelt, der angibt, um wieviel länger die mit dem Licht schutzmittel geschützte Haut mit UV-A-Strahlung bestrahlt werden kann, bis die gleiche Pigmentierung auftritt wie bei der ungeschützten Haut.The IPD method is usually used to test UV-A protection (IPD ∼ immediate pigment darkening). Here - similar to the determination of light protection factor - determines a value that indicates how much longer the light Protected skin can be irradiated with UV-A radiation until the same Pigmentation occurs as with unprotected skin.
Die Einsatzkonzentration bekannter Lichtschutzfiltersubstanzen, die insbesondere auch im UV-A-Bereich eine hohe Filterwirkung zeigen, ist häufig gerade in Kombination mit anderen als Festkörper vorliegenden Substanzen begrenzt. Es bereitet daher gewisse formulierungstechnische Schwierigkeiten, höhere Lichtschutzfaktoren bzw. UV-A-Schutzleistung zu erzielen.The use concentration of known light protection filter substances, in particular also show a high filter effect in the UV-A range, is often in combination with other substances present as solids limited. It therefore prepares certain formulation difficulties, higher sun protection factors or Achieve UV-A protection performance.
Da Lichtschutzfiltersubstanzen in der Regel kostspielig sind und da manche Lichtschutz filtersubstanzen zudem schwierig in höheren Konzentrationen in kosmetische oder dermatologische Zubereitungen einzuarbeiten sind, war es Aufgabe der Erfindung, auf einfache und preiswerte Weise zu Zubereitungen zu gelangen, welche bei un gewöhnlich niedrigen Konzentrationen an herkömmlichen UV-A-Lichtschutzfiltersubstan zen dennoch eine akzeptable oder sogar hohe UV-A-Schutzleistung erreichen.Since light protection filter substances are usually expensive and some light protection Filter substances also difficult in higher concentrations in cosmetic or to incorporate dermatological preparations, it was the object of the invention simple and inexpensive way to get preparations that are available at un usually low concentrations of conventional UV-A light protection filter substances zen nevertheless achieve an acceptable or even high UV-A protection performance.
Es war indes überraschend und für den Fachmann nicht vorauszusehen, daß die Ver wendung von synthetischem Bienenwachs zur Erhöhung der UV-A-Schutzleistung kosmetischer oder dermatologischer Zubereitungen, enthaltend mindestens eine übliche UV-A-Filtersubstanz und/oder eine Breitbandfiltersubstanz, die auch gegen UV-Strahlung mit einer Wellenlänge, die größer als 335 nm ist, Schutz gewährt, den Nach teilen des Standes der Technik abhelfen würde.It was surprising, however, and it could not have been foreseen by the skilled person that the Ver Use of synthetic beeswax to increase UV-A protection cosmetic or dermatological preparations containing at least one conventional one UV-A filter substance and / or a broadband filter substance that also works against UV radiation with a wavelength greater than 335 nm provides protection, the night would help share the state of the art.
Bienenwachs ist ein Ausscheidungsprodukt aus Drüsen der Honigbienen, das diese zum Bauen der Honigwaben verwenden. Gelbes (Cera flava), braunes oder rotes so genanntes Rohwachs ist beispielsweise erhältlich, indem man die vom Honig durch Ausschleudern befreiten Waben schmilzt, die Schmelze (Schmp. 60-82°C) von festen Verunreinigungen trennt und das so erhaltene Rohwachs erstarren läßt. Das Rohwachs kann durch Behandlung mit Oxidationsmitteln vollkommen weiß gebleicht werden (Cera alba).Beeswax is an excretion product from the honeybee's glands that this use to build the honeycomb. Yellow (Cera flava), brown or red like this The raw wax mentioned can be obtained, for example, by using honey Extracting honeycomb melts, the melt (melting point 60-82 ° C) of solid Separates impurities and solidifies the raw wax thus obtained. The raw wax can be bleached completely white by treatment with oxidizing agents (Cera alba).
Bienenwachs besteht zu ca. 70% aus einem Myricin genannten Gemisch von etwa 70 komplexen Wachsestern von C16- bis C36-Säuren und C24- bis C36-Alkoholen, zu 13 bis 14% aus normalen Fettsäuren und Hydroxyfettsäuren sowie zu 10 bis 14% aus Koh lenwasserstoffen.Beeswax consists of approximately 70% myricin, a mixture of approximately 70 complex wax esters of C 16 to C 36 acids and C 24 to C 36 alcohols, 13 to 14% of normal fatty acids and hydroxy fatty acids and 10 to 14% from hydrocarbons.
