Description
Die vorliegende Erfindung betrifft eine kosmetische Lichtschutzemulsion enthaltend UV-Lichtschutzfilterpigmente in einer Konzentration von mindestens 20 Gewichts-%, bezogen auf das Gesamtgewicht der Zubereitung.The The present invention relates to a cosmetic sunscreen emulsion containing UV photoprotective pigments in a concentration of at least 20% by weight, based on the total weight of the preparation.
Der Trend weg von der vornehmen Blässe hin zur „gesunden, sportlich braunen Haut" ist seit Jahren ungebrochen. Um diese zu erzielen setzen die Menschen ihre Haut der Sonnenstrahlung aus, da diese eine Pigmentbildung im Sinne einer Melaninbildung hervorruft. Die ultraviolette Strahlung des Sonnenlichtes hat jedoch auch eine schädigende Wirkung auf die Haut. Neben der akuten Schädigung (Sonnenbrand) treten Langzeitschäden wie ein erhöhtes Risiko an Hautkrebs zu erkranken bei übermäßiger Bestrahlung mit Licht aus dem UVB-Bereich (Wellenlänge: 280–320 nm) auf. Die übermäßige Einwirkung der UVB- und UVA-Strahlung (Wellenlänge: 320–400 nm) führt darüber hinaus zu einer Schwächung der elastischen und kollagenen Fasern des Bindegewebes. Dies führt zu zahlreichen phototoxischen und photoallergischen Reaktionen und hat eine vorzeitige Hautalterung zur Folge.Of the Trend away from the noble paleness towards the "healthy, sporty brown skin "is unbroken for years. To achieve this people are putting Their skin of solar radiation, as this is a pigmentation in the sense of melanin formation. The ultraviolet radiation However, sunlight also has a damaging effect on the skin. Besides the acute injury (Sunburn) occur long-term damage like an elevated one Risk of developing skin cancer from excessive exposure to light from the UVB range (wavelength: 280-320 nm). Excessive influence UVB and UVA radiation (wavelength: 320-400 nm) leads beyond that to a weakening the elastic and collagen fibers of the connective tissue. This leads to numerous phototoxic and photoallergic reactions and has a premature Skin aging results.
Zum Schutz der Haut wurden daher eine Reihe von Lichtschutzfiltersubstanzen entwickelt, die in kosmetischen Zubereitungen eingesetzt werden können. Diese UVA- und UVB-Filter sind in den meisten Industrieländern in Form von Positivlisten wie der Anlage 7 der deutschen Kosmetikverordnung zusammengefasst.To the Protection of the skin were therefore a set of sunscreen filter substances developed, which are used in cosmetic preparations can. These UVA and UVB filters are available in most industrialized countries Form of positive lists such as Annex 7 of the German Cosmetics Regulation summarized.
Eine besondere Form von UV-Lichtschutzfiltersubstanzen stellen die Mikropigmente dar. Die UV-Schutzwirkung der Mikropigmente beruht auf den physikalischen Effekten der Reflexion und Lichtstreuung. In kosmetischen Zubereitungen werden als Mikropigmente fast ausschließlich anorganische Mikropigmente aus Titandioxid, Zinkoxid oder Mischoxiden mit zum Beispiel Eisenoxiden eingesetzt.A special form of UV sunscreen filter substances are the micropigments The UV protective effect of the micropigments is based on the physical Effects of reflection and light scattering. In cosmetic preparations are almost exclusively inorganic micropigments as micropigments Titanium dioxide, zinc oxide or mixed oxides with, for example, iron oxides used.
Die Vorteile von Mikropigmenten als UV-Filtersubstanz in kosmetischen Zubereitungen liegen vor allem darin begründet, dass die Pigmente im Gegensatz zu gelöst oder flüssig vorliegenden, nicht in die Haut penetrieren. Das Auftreten von allergischen Reaktionen ist damit ausgeschlossen.The Advantages of micropigments as UV filter substance in cosmetic Preparations are mainly due to the fact that the pigments in the Contrast to solved or liquid present, do not penetrate into the skin. The occurrence of allergic Reactions are excluded.
Nachteilig am Stande der Technik ist jedoch der Umstand, dass Mikropigmente nur schwer stabil in kosmetische Zubereitungen einzuarbeiten sind. Insbesondere wenn Mikropigmente in höheren Konzentrationen (Konzentrationen über 7 Gewichts-%, bezogen auf das Gesamtgewicht der Zubereitung) eingesetzt werden, bilden sie relativ schnell Pigment-Agglomerate, die aus der Zubereitung ausfallen. Die Lagerstabilität ist also gering.adversely However, the state of the art is the fact that micropigments difficult to incorporate stable into cosmetic preparations. In particular, when micropigments are present in higher concentrations (concentrations above 7% by based on the total weight of the preparation), They form pigment agglomerates relatively quickly from the preparation fail. The storage stability is so low.
Es war daher die Aufgabe der vorliegenden Erfindung, die Mängel des Standes der Technik zu beseitigen und stabile Emulsionen mit einem hohen Gehalt an Mikropigmenten als UV-Lichtschutzfilter zu entwickeln. Die Formulierungen sollten ferner bei Ihrer Anwendung auf der Haut ein über einen längeren Anwendungszeitraum stabiles Absorptionsspektrum mit einer ausgewogenen UV-A/UV-B-Absorptionsbalance aufweisen.It Therefore, the object of the present invention, the shortcomings of Prior art eliminate and stable emulsions with a high content of micropigments to develop as a UV light protection filter. The In addition, formulations should be applied over the skin when applied to the skin longer Application period stable absorption spectrum with a balanced Have UV-A / UV-B absorption balance.
Überraschend gelöst werden die Aufgaben durch eine kosmetische Lichtschutzemulsion enthaltend organische und anorganische UV-Lichtschutzfilterpigmente in einer Konzentration von mindestens 20 Gewichts-%, bezogen auf das Gesamtgewicht der Zubereitung, dadurch gekennzeichnet, dass das Gewichtsverhältnis von anorganischen zu organischen UV-Lichtschutzfilterpigmenten von 4:1 bis 1:4 beträgt.Surprised solved The objects are achieved by a cosmetic sunscreen emulsion containing organic and inorganic UV photoprotective pigments in a concentration of at least 20% by weight, based on the total weight of the Preparation, characterized in that the weight ratio of inorganic to organic UV photoprotective pigments from 4: 1 to 1: 4.
