Description
Die vorliegende Erfindung betrifft eine kosmetische Zubereitung, die in Form einer wässrigen Zubereitung oder einer O/W-Emulsion vorliegt, enthaltend partikuläre anorganische UV-Lichtschutzfilterpigmente mit einer durchschnittlichen Partikelgröße von 10 bis 500 nm, partikuläre organische UV-Lichtschutzfilterpigmente in einer Gesamtmenge von mindestens 5 Gewichts-%, bezogen auf das Gesamtgewicht der Zubereitung.The The present invention relates to a cosmetic preparation which in the form of an aqueous Preparation or an O / W emulsion containing particulate inorganic UV sunscreen pigments with an average particle size of 10 to 500 nm, particulate organic UV sunscreen filter pigments in a total of at least 5% 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 the UVB and UVA radiation (wavelength: 320-400 nm) leads about that out 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 anorganischen Mikropigmente dar. Die UV-Schutzwirkung der Mikropigmente beruht auf den physikalischen Effekten der Reflexion und Lichtstreuung. In kosmetischen Zubereitungen werden als anorganische Mikropigmente meist Pigmente aus Titandioxid, Zinkoxid oder Mischoxiden mit zum Beispiel Eisenoxiden eingesetzt.A special form of UV sunscreen filter substances represent the inorganic Micropigments. The UV protection effect of the micropigments is based on the physical effects of reflection and light scattering. In cosmetic preparations are called inorganic micropigments usually pigments of titanium dioxide, zinc oxide or mixed oxides with the Example iron oxides used.
Die Vorteile von anorganischen Mikropigmenten als UV-Filtersubstanz in kosmetischen Zubereitungen liegen vor allem darin begründet, dass die Pigmente im Gegensatz zu organischen Lichtschutzfiltern, physikalisch und chemisch besonders stabil sind. Sie neigen selbst bei starker UV-Strahlung nicht zur Zersetzung oder zu Photoreaktionen. Aufgrund der Tatsache, dass es sich bei den Pigmenten um Feststoffe handelt, besteht keine Gefahr einer übermäßigen Penetration der Filter in die Haut. Das Auftreten von allergischen Reaktionen ist damit ausgeschlossen.The Advantages of inorganic micropigments as UV filter substance in cosmetic preparations are mainly due to the fact that the pigments in contrast to organic sunscreens, physically and are particularly stable chemically. They tend to strong even UV radiation not for decomposition or photoreactions. by virtue of the fact that the pigments are solids, there is no danger of excessive penetration the filter in the skin. The occurrence of allergic reactions is excluded.
Nachteilig am Stande der Technik ist jedoch der Umstand, dass anorganische 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. Auch bei der Anwendung auf der Haut führen höhere Konzentrationen von anorganischen Mikropigmenten schnell zur Agglomeration die in Form von weißen Flecken und Streifen („weißeln") auf der Haut sichtbar und vom Anwender als unästhetisch empfunden werden. Ferner führt die Bildung der Agglomerate zu einer Veränderung im Absorptionsverhalten der Pigmente während der Anwendung. Größere Agglomerate absorbieren überwiegend im Bereich des sichtbaren Lichtes (daher das „weißeln") sowie im UV-A-Bereich, während kleinere Partikel ihr Absorptionsmaximumm im UV-B-Bereich besitzen. Darüber hinaus ist die UV-Lichtschutzwirkung von größeren Teilchen deutlich geringer als die von Mikropigmenten. Nach dem Stande der Technik ist es also nahezu unmöglich, kosmetische UV-Lichtschutzzubereitungen auf der Basis von anorganischen Mikropigmenten herzustellen, die während der Dauer ihrer Anwendung ein stabiles und ausgewogenes Absorptionsspektrum aufweisen.adversely However, the state of the art is the fact that inorganic Micropigments difficult to incorporate stable in cosmetic preparations are. 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. Even when applied to the skin result in higher concentrations of inorganic micropigments fast to agglomeration the in Form of white Patches and streaks ("whingles") visible on the skin and by the user as unaesthetic be felt. Further leads the formation of agglomerates to a change in the absorption behavior of the pigments during the application. Larger agglomerates absorb predominantly in the range of visible light (hence the "whitening") as well as in the UV-A range, while smaller ones Particles have their absorption maximum in the UV-B range. Furthermore the UV light protection effect of larger particles is significantly lower as that of micropigments. So it's the state of the art almost impossible, Cosmetic UV light protection preparations based on inorganic Micropigments to be produced during the period of their application have a stable and balanced absorption spectrum.
Nach dem Stand der Technik lassen sich diese Probleme allein dadurch begrenzen, dass als kosmetische Grundlage der Sonnenschutzzubereitung eine Wasser-in-Öl-Emulsion (W/O-Emulsion) eingesetzt werden. W/O-Emulsionen weisen aber, da ihre äußere Phase von der Ölphase gebildet wird, in der Regel ein eher ölig-fettiges Hautgefühl auf. W/O-Emulsionen mit einem erhöhten Gehalt an -anorganischen Mikropigmenten wirken darüber hinaus zäh und lassen sich nur schwer auf der Haut verteilen. Um die Verteilbarkeit solcher Zubereitungen zu verbessern, müssen den Formulierungen Silikonöle zugesetzt werden, was häufig nicht erwünscht ist.To In the prior art, these problems can be solved alone limit that as a cosmetic basis of sunscreen preparation a water-in-oil emulsion (W / O emulsion) used become. W / O emulsions, however, have their outer phase formed by the oil phase is usually a rather oily-greasy skin feel on. W / O emulsions with an increased content of inorganic compounds Micropigments work over it tough and tough are difficult to distribute on the skin. To the distributability To improve such preparations, silicone oils must be added to the formulations be what often not wanted is.
In die kosmetisch-sensorisch attraktiveren Öl-in-Wasser-Emulsionen (O/W-Emulsionen) ließen sich bisher keine größeren Mengen an anorganischen Mikropigmenten einarbeiten, ohne dass die beschriebenen Nachteile (z.B. mangelnde Stabilität) zu vermeiden gewesen wären. Es ließen sich allenfalls Zubereitungen mit geringem Lichtschutzfaktor stabil formulieren. O/W-Lichtschutzemulsionen mit hohem Lichtschutzfaktor ließen sich, nach dem Stand der Technik, nur mit Hilfe flüssiger oder gelöster organischer Lichtschutzfilter erreichen. Neben dem Problem der Hautpenetration dieser Filter, weisen die Zubereitungen insbesondere bei höheren Filterkonzentrationen, ein fettig-klebriges Hautgefühl auf.The cosmetically-sensory-attractive oil-in-water emulsions (O / W emulsions) have hitherto been unable to incorporate relatively large amounts of inorganic micropigments without those described Disadvantages (eg lack of stability) would have been avoided. At best, formulations with a low sun protection factor could be formulated in a stable manner. O / W sunscreen emulsions with a high SPF could, according to the prior art, only be achieved with the aid of liquid or dissolved organic sunscreen filters. In addition to the problem of skin penetration of these filters, the preparations have a greasy-sticky feel on the skin, especially at higher filter concentrations.
Aufgabe der vorliegenden Erfindung war es daher, die Nachteile des Standes der Technik zu beseitigen und kosmetische Lichtschutzzubereitungen mit hohem Lichtschutzfaktor auf wässriger Basis oder auf der Basis von Öl-in-Wasser-Emulsionen (O/W-Emulsionen) zu entwickeln, deren UV-Filtersystem auf Mikropigmenten basiert. Diese Zubereitungen sollten insbesondere lager- und transportstabil sein und eine Agglomeration der Mikropigmente während der Lagerung und der Anwendung wirkungsvoll unterdrücken. 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.task It was therefore the object of the present invention to overcome the disadvantages of the prior art eliminate the technique and cosmetic sunscreen preparations with a high sun protection factor on a watery basis or on the basis of oil-in-water emulsions (O / W emulsions) to develop their UV filter system on micropigments based. These preparations should in particular be stable on storage and transport and an agglomeration of the micropigments during storage and the Effectively suppress application. The formulations should also be applied to your skin when applied one over a longer one Application period stable absorption spectrum with a balanced UV-A / UV-B absorption Balance exhibit.
