Physikalische Lichtschutzfilter wirken auf der Haut verteilt wie kleine Spiegel, die die UV-Strahlung reflektieren und streuen. Als physikalische Lichtschutzfilter werden vor allem unlösliche anorganische Pigmente auf Basis von Metalloxiden verwendet, beispielsweise Titandioxid, Zinkoxid, Eisenoxid oder Siliciumdioxid. Da diese Pigmente in Lichtschutzzubereitungen nicht löslich sind, werden sie, um ein angenehmes Hautgefühl zu vermitteln, ein übermäßiges "Weißein" beim Auftragen der Lichtschutzzubereitung zu vermeiden sowie zur Vermeidung von abdeckenden Effekten wie zum Beispiel bei Make-up's, vorzugsweise in mikronisierter Form eingesetzt, vorzugsweise mit einer Partikelgröße kleiner als 100 nm.Physical sun protection filters act like small mirrors when distributed on the skin, reflecting and scattering UV radiation. Physical sun protection filters are mainly insoluble inorganic pigments based on metal oxides, for example titanium dioxide, zinc oxide, iron oxide or silicon dioxide. Since these pigments are not soluble in sun protection preparations, they are preferably used in micronized form, preferably with a particle size of less than 100 nm, in order to provide a pleasant skin feel, to avoid excessive "whitening" when applying the sun protection preparation, and to avoid covering effects such as with make-up.

Durch chemische Lichtschutzfilter wird die auf die Haut auftreffende UV-Strahlung in Wärmeenergie umgewandelt. Chemische Lichtschutzfilter können sowohl lipophile als auch hydrophile Eigenschaften aufweisen und entsprechend dieser Eigenschaften unterscheidet man zwischen öllöslichen und wasserlöslichen Filtern. Da die menschliche Haut sowohl lipophile als auch hydrophile Bereiche aufweist, ist es für eine möglichst flächendeckende Wirkung eines Sonnenschutzmittels vorteilhaft, wenn dieses sowohl öllösliche als auch wasserlösliche Filtersubstanzen enthält.Chemical sun protection filters convert the UV radiation that hits the skin into heat energy. Chemical sun protection filters can have both lipophilic and hydrophilic properties and, depending on these properties, a distinction is made between oil-soluble and water-soluble filters. Since human skin has both lipophilic and hydrophilic areas, it is advantageous for a sunscreen to have the most comprehensive effect possible if it contains both oil-soluble and water-soluble filter substances.

Neben der reinen Lichtschutzwirkung werden an Lichtschutzzubereitungen aber auch zunehmend höhere Anforderungen hinsichtlich ihrer Hautverträglichkeit gestellt. Herkömmliche Lichtschutzzubereitungen enthalten neben den Filtersubstanzen oftmals Emulgatoren, Fette, fettähnliche Substanzen und/oder Siliconverbindungen, die verschiedenen Zwecken dienen sollen. So werden solche Hilfsmittel zur Solubilisierung der in diesen Mitteln eingesetzten UV-filternden Substanzen, zur Erzielung rückfettender Eigenschaften, zur Verbesserung der Spreitfähigkeit der Produkte, zur Herstellung von Emulsionen und/oder zur Einstellung der Viskosität verwendet. Allerdings werden diese Substanzen schon seit längerem im Zusammenhang mit Unverträglichkeitsreaktionen, wie beispielsweise der bekannten "Mallorca-Akne", kritisch diskutiert.In addition to the pure sun protection effect, increasingly higher demands are also being placed on sun protection preparations in terms of their skin compatibility. In addition to the filter substances, conventional sun protection preparations often contain emulsifiers, fats, fat-like substances and/or silicone compounds, which are intended to serve various purposes. Such aids are used to solubilize the UV-filtering substances used in these products, to achieve moisturizing properties, to improve the spreadability of the products, to produce emulsions and/or to adjust the viscosity. However, these substances have long been the subject of critical discussion in connection with intolerance reactions, such as the well-known "Mallorca acne".

Lichtschutzzubereitungen werden oftmals als Öle, Emulsionen, Lotionen oder Gele formuliert, wobei Gele den Vorteil einer besonders guten Hautverträglichkeit bieten. Als besonders vorteilhaft haben sich dabei Lichtschutzzubereitungen in Form von Hydrodispersionsgelen erwiesen.Sunscreen preparations are often formulated as oils, emulsions, lotions or gels, with gels offering the advantage of being particularly well tolerated by the skin. Sunscreen preparations in the form of hydrodispersion gels have proven to be particularly advantageous.

Aus der DE 195 47 634 sind Hydrodispersionsgele bekannt, die zwingend einen Gehalt an Polyacrylaten als Konsistenzgeber aufweisen. Derartige Polyacrylate, beispielsweise aus der Pemulen® oder Carbolpol®-Reihe werden vielfach als Dickungsmittel bzw. Konsistenzgeber zur Formulierung von Sonnenschutzzubereitungen verwendet. Derartige Polyacrylate zeigen jedoch diverse Nachteile, wie beispielsweise den Restlösemittelgehalt einiger Polyacrylattypen, eine hohe Empfindlichkeit gegenüber Salzen (die bei seewasserfesten Lichtschutzformulierungen sowie wegen der auf der Hautoberfläche, z.B. durch starkes Schwitzen befindlichen Salzen nachteilig ist), die Notwendigkeit der pH-Wert-Einstellung (Neutralisation), die oftmals mit Triethanolamin erfolgt, wobei sich bei letzterem wiederum das Problem der Nitrosaminbildung darstellt.DE 195 47 634 discloses hydrodispersion gels that necessarily contain polyacrylates as consistency agents. Such polyacrylates, for example from the Pemulen® or Carbolpol® series, are often used as thickeners or consistency agents in the formulation of sun protection preparations. However, such polyacrylates have various disadvantages, such as the residual solvent content of some types of polyacrylate, a high sensitivity to salts (which is disadvantageous in seawater-resistant sun protection formulations and because of the salts on the skin surface, e.g. due to heavy sweating), the need for pH adjustment (neutralization), which is often carried out with triethanolamine, with the latter in turn presenting the problem of nitrosamine formation.

Aufgabe der vorliegenden Erfindung ist es somit, ein gut verträgliches, stabiles gelförmiges Lichtschutzmittel anzugeben, das sowohl öllösliche als auch wasserlösliche Lichtschutzfilter umfaßt und darüber hinaus frei von Polyacrylaten ist.The object of the present invention is therefore to provide a well-tolerated, stable gel-like sunscreen agent which comprises both oil-soluble and water-soluble sunscreen filters and is also free of polyacrylates.

Diese Aufgabe wird durch die im unabhängigen Anspruch definierte Zusammensetzung gelöst.This problem is solved by the composition defined in the independent claim.

Die abhängigen Ansprüche definieren vorteilhafte Ausführungsformen der Erfindung.The dependent claims define advantageous embodiments of the invention.

Gemäß der vorliegenden Erfindung wurde überraschend gefunden, daß unter Verwendung von Magnesium-Aluminiumsilikat kosmetisch akzeptable Hydrodispersionsgele mit ausreichend hohen Lichtschutzfaktoren formuliert werden können. Der Vorteil von Magnesium-Aluminiumsilikat liegt darin, daß es sich hierbei um ein natürliches ProduktAccording to the present invention, it was surprisingly found that cosmetically acceptable hydrodispersion gels with sufficiently high sun protection factors can be formulated using magnesium aluminum silicate. The advantage of magnesium aluminum silicate is that it is a natural product

handelt, das nicht die oben diskutierten Nachteile der in vorbekannten Formulierungen verwendeten Polyacrylate zeigt. Insbesondere tritt bei der Verwendung von Magnesium-Aluminiumsilikat nicht die Restlösemittelproblematik auf. Darüber hinaus ist es nicht salzempfindlich und bedarf auch keinerlei Neutralisationsschritte.which does not exhibit the disadvantages discussed above of the polyacrylates used in previously known formulations. In particular, the use of magnesium aluminum silicate does not result in the residual solvent problem. In addition, it is not sensitive to salt and does not require any neutralization steps.

Die Hydrodispersionsgelsysteme gemäß der vorliegenden Erfindung sind an sich bekannt. Sie umfassen grundsätzlich eine Ölphase, mindestens einen UV-Filter sowie Wasser. Die Ölphase kann dabei aus Fetten, Ölen, gelösten Wachsen oder sonstigen lipophilen Bestandteilen und/oder auch aus den öllöslichen Filtersubstanzen selbst bestehen. Als Öle können vorteilhaft Paraffinöl, mittelkettige Triglyceride, wie beispielsweise Pentylenglycol, Jojobaöl, Kokosöl, Erdnußöl oder Rizinusöl in einer Menge von 1 bis 10 Gew.-% enthalten sein.The hydrodispersion gel systems according to the present invention are known per se. They basically comprise an oil phase, at least one UV filter and water. The oil phase can consist of fats, oils, dissolved waxes or other lipophilic components and/or of the oil-soluble filter substances themselves. Oils can advantageously be paraffin oil, medium-chain triglycerides, such as pentylene glycol, jojoba oil, coconut oil, peanut oil or castor oil in an amount of 1 to 10% by weight.
