Description
Die vorliegende Erfindung betrifft eine kosmetische Zubereitung enthaltend Octylsalicylat (Ethylhexyl Salicylat) und Titandioxid in der Kristallstruktur Rutil mit einer Primärpartikelgröße von 2 -100 nm.The present invention relates to a cosmetic preparation containing octyl salicylate (ethylhexyl salicylate) and titanium dioxide in the rutile crystal structure with a primary particle size of 2-100 nm.
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.The trend away from elegant paleness towards "healthy, sporty brown skin" has been unbroken for years. In order to achieve this, people expose their skin to solar radiation, as this causes pigment formation in the sense of melanin formation. However, the ultraviolet radiation in sunlight also has a damaging effect on the skin. In addition to the acute damage (sunburn), long-term damage such as an increased risk of developing skin cancer occurs with excessive exposure to light from the UVB range (wavelength: 280-320 nm). Excessive exposure to UVB and UVA radiation (wavelength: 320-400 nm) also leads to a weakening of the elastic and collagen fibers of the connective tissue. This leads to numerous phototoxic and photoallergic reactions and results in premature skin aging.
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 dem Anlage 7 der Kosmetikverordnung zusammengefasst.To protect the skin, a number of light protection filter substances have therefore been developed which can be used in cosmetic preparations. In most industrialized countries, these UVA and UVB filters are summarized in the form of positive lists such as Annex 7 of the Cosmetics Ordinance.
Die Vielzahl an kommerziell erhältlichen Sonnenschutzmitteln darf jedoch nicht darüber hinwegtäuschen, dass diese Zubereitungen des Standes der Technik eine Reihe von Nachteilen aufweisen.However, the large number of commercially available sunscreens should not obscure the fact that these prior art preparations have a number of disadvantages.
So sind im Stande der Technik eine Vielzahl von Sonnenschutzmitteln bekannt, die als UV-Filter mikronisiertes Titandioxid enthalten. Dabei werden in der Regel Titandioxide eingesetzt, die ganz oder teilweise in der Kristallstruktur Anatas vorliegen, beispielsweise das Titandioxid mit dem Handelsnamen Tego Sun T 805 von Evonik, welches eine Mischung aus den Kristallstrukturen Anatas/Rutil von etwa 80:20 aufweist. Zubereitungen mit Titandioxid in Anatas-Struktur haben dabei den Vorteil, transparenter zu sein als vergleichbare Zubereitungen mit Titandioxid in Rutil-Struktur.A large number of sunscreens which contain micronized titanium dioxide as a UV filter are known in the prior art. As a rule, titanium dioxides are used which are wholly or partly present in the anatase crystal structure, for example the titanium dioxide with the trade name Tego Sun T 805 from Evonik, which has a mixture of the anatase/rutile crystal structures of about 80:20. Preparations with titanium dioxide in anatase structure have the advantage of being more transparent than comparable preparations with titanium dioxide in rutile structure.
Nachteilig am Stande der Technik ist jedoch der Umstand, dass die Zubereitungen enthaltend Titandioxid in Anatas-Struktur relativ schlechte Filme auf der Haut bilden. Diese Filmbildung kann dabei experimentell im Labor mit Hilfe Fluoreszenzlöschmethode bestimmt werden.However, a disadvantage of the prior art is the fact that the preparations containing titanium dioxide with an anatase structure form relatively poor films on the skin. This film formation can be determined experimentally in the laboratory using the fluorescence quenching method.
Es war daher die Aufgabe der vorliegenden Erfindung, ein Sonnenschutzmittel auf der Basis von mikronisiertem Titandioxid zu entwickeln, bei dem die Filmbildung (d.h. die Ausbildung einer homogenen, möglichst lückenlosen Produktschicht auf der Haut) verbessert ist.It was therefore the object of the present invention to develop a sun protection agent based on micronized titanium dioxide in which film formation (i.e. the formation of a homogeneous product layer with as few gaps as possible on the skin) is improved.
Nachteilig am Stande der Technik ist darüber hinaus der Umstand, dass viele Titandioxid enthaltende Sonnenschutzmittel bei der Lagerung über einen längeren Zeitraum zur Bildung von Gasbläschen neigen. Diese Gasbildung (Wasserstoff) tritt dabei auch bei beschichteten Titandioxiden immer wieder auf. Es war daher die Aufgabe der vorliegenden Erfindung, ein Sonnenschutzmittel auf der Basis von mikronisiertem Titandioxid zu entwickeln, bei dem die Gasbildung während der Lagerung wirkungsvoll unterdrückt ist.Another disadvantage of the prior art is the fact that many sunscreens containing titanium dioxide tend to form gas bubbles when stored over a relatively long period of time. This gas formation (hydrogen) also occurs again and again with coated titanium dioxide. It was therefore the object of the present invention to develop a sunscreen based on micronized titanium dioxide in which gas formation during storage is effectively suppressed.

Die Filmbildung lässt sich dabei mit Hilfe der Fluoreszenzlöschmethode wie folgt bestimmen:
- Eingesetzte Methode: Löschung von Papierfluoreszenz
- Method used: quenching of paper fluorescence
Prinzip: Druckerpapieren werden optische Aufheller zugesetzt, die bei Bestrahlung mit UV-Licht blau fluoreszieren. Wenn ein Produktfilm mit UV-Schutz auf dem Papier liegt, wird die Fluoreszenz, je nach Stärke des UV-Schutzes, geschwächt oder ganz gelöscht. So kann der UV-Schutz auf einfache Weise beurteilt werden.Principle: Optical brighteners are added to printer paper, which fluoresce blue when exposed to UV light. If a product film with UV protection is on the paper, the fluorescence will be weakened or completely extinguished, depending on the strength of the UV protection. This makes it easy to assess UV protection.
Durchführung: Für jede Emulsion wurde ein neuer und unbenutzter Latexfingerling auf den rechten Zeigefinger aufgezogen und 30 s mit der jeweiligen Emulsion eingerieben (Sättigung des Fingerlings mit der Emulsion). Anschließend wurde eine kleine Menge der jeweiligen Emulsion auf ein Stückchen Vitro Skin aufgetragen und ebenfalls 30 s lang mit dem behandschuhten Finger eingerieben (Einstellung Gleichgewicht Fingerling/Kunsthautoberfläche). Als nächster Schritt wurden 28,0 +/- 0,4 mg der entsprechenden Emulsion auf ein Vitro-Skin-Objektträger übertragen. Dabei wurde die Emulsion erst einmal punktförmig auf der künstlichen Haut verteilt. Im Anschluss wurde die Emulsion erst mit kreisenden Bewegungen, dann jeweils in Quer- und Längsrichtung zum Objektträger eingerieben, wobei die „Einreibungsdauer“ 30 s. betrug. Damit ergibt sich eine Auftragsmenge von 2 mg Emulsion / cm2. Nach der Auftragung des letzten Objektträgers wurden alle Vitro-Skin-Objektträger 20 Minuten bei Raumtemperatur getrocknet. Im Anschluss an die Trocknungszeit wurden Aufnahmen mit einer Digitalkamera bei den verschiedenen Anregungsbereichen Tageslicht, 312 nm UVB, 366 nm UVA (2x6W UV-Lampe, Firma VILBER LOURMAT) angefertigt und anschließend per Bildauswertungssoftware (analySIS start, Firma Olympus) über die Blauwerte (RGB-Farbraum rot/grün/blau, jeweils 0 bis 255, horizontal über die Plattenbreite gemittelte Werte) ausgewertet.Implementation: For each emulsion, a new and unused latex fingerstall was put on the right index finger and rubbed in with the respective emulsion for 30 s (saturation of the fingerstall with the emulsion). A small amount of the respective emulsion was then applied to a piece of Vitro Skin and also rubbed in for 30 s with a gloved finger (setting the balance between finger stall and artificial skin surface). As a next step, 28.0 +/- 0.4 mg of the appropriate emulsion was transferred to a Vitro Skin slide. The emulsion was first distributed in dots on the artificial skin. The emulsion was then rubbed in first with circular movements, then in each case in the transverse and longitudinal direction to the slide, with the “rubbing time” being 30 s. This results in an application quantity of 2 mg emulsion/cm 2 . After the last slide was applied, all Vitro Skin slides were dried at room temperature for 20 minutes. After the drying time, pictures were taken with a digital camera for the different excitation ranges of daylight, 312 nm UVB, 366 nm UVA (2x6W UV lamp, company VILBER LOURMAT) and then using image evaluation software (analySIS start, company Olympus) via the blue values (RGB color space red/green/blue, each 0 to 255, values averaged horizontally over the width of the plate).

Vergleichsversuchcomparison test
Mit Hilfe des folgenden Vergleichsversuches konnte der erfinderische Effekt beispielhaft belegt werden:
Methode: Löschung von Papierfluoreszenz, DoppelbestimmungMethod: Paper fluorescence quenching, duplicate determination
Die Methodenbeschreibung findet sich auf Seite 2-3The method description can be found on page 2-3
Die Auswertung erfolgt über die Anregung bei 312 nm (UVB), wobei gilt, dass die Fluoreszenzlöschung je größer ist, je geringer der verbleibende Blauwert ist.The evaluation is carried out via the excitation at 312 nm (UVB), whereby the lower the remaining blue value, the greater the quenching of the fluorescence.
Proben: s. Tabelle oben, PMCCBB10#138 und #140Samples: see table above, PMCCBB10#138 and #140
Ergebnisse:Results:
Werden die 312 nm-Aufnahmen (Unterschiede in diesen am deutlichsten erkennbar) per Bildauswertungssoftware über die Blauwerte* ausgewertet, erhält man folgende Werte:
* RGB-Farbraum (rot/grün/blau, jeweils 0 bis 255), horizontal über die Plattenbreite gemittelte WerteIf the 312 nm recordings (differences in these are most clearly recognizable) are evaluated using image evaluation software via the blue values*, the following values are obtained:
* RGB color space (red/green/blue, each 0 to 255), values averaged horizontally over the plate width
Anhand dieser Werte lässt sich deutlich erkennen, dass die Fluoreszenzlöschung von Ansatz #138 (mit Titandioxid Rutil-Typ) stärker ausgeprägt/besser ist als bei Ansatz #140 (mit Titandioxid Anastase-Typ).From these values it can be clearly seen that the fluorescence quenching of batch #138 (with titanium dioxide rutile type) is more pronounced/better than batch #140 (with titanium dioxide anatase type).
Das bedeutet, dass der Ansatz #138 (mit Titandioxid Rutil-Typ) eine deutlich bessere Filmbildung bewirkt als der vergleichend getestete Ansatz #140 (mit Titandioxid Anastase-Typ).This means that batch #138 (with rutile-type titanium dioxide) produces significantly better film formation than batch #140 (with anatase-type titanium dioxide), which was tested for comparison.
