Unter Kosmetik kann man alle Maßnahmen zusammenfassen, die aus ästhetischen Gründen Veränderungen an Haut und Haaren vornehmen oder zur Körperreinigung angewendet werden. Kosmetik bedeutet also, das Körperäußere zu pflegen, zu verbessern und zu verschönern, um auf sichtbare, fühlbare und riechbare Weise sowohl den Mitmenschen als auch sich selbst zu gefallen. Schon vor Jahrtausenden wurdeUnder cosmetics, one can summarize all measures that make changes to the skin and hair for aesthetic reasons or to cleanse the body. Cosmetics, then, means to care for, improve and beautify the outer body in order to please the fellow human being as well as oneself in a visible, tangible and smelly way. Millennia ago
Kosmetik vom Menschen zu diesem Zweck angewandt. Man färbte Lippen und Gesicht, salbte sich mit wertvollen ölen und badete in duftendem Wasser.Cosmetics applied by humans for this purpose. One colored lips and face, anointed itself with valuable oils and bathed in fragrant water.
Schon seit langem befindet sich die Fachwelt auf der Suche nach kosmetischen Zubereitungen, die gegen Falten oder Cellulite wirksam sind.The experts have long been searching for cosmetic preparations that are effective against wrinkles or cellulite.
Eine für den Verbraucher sehr wesentliche, dabei aber nur schwer quantitativ meßbare Eigenschaft kosmetischer Produkte ist ein bestimmtes belebendes und/oder glattes Hautgefühl sowie die Geschmeidigkeit der Haut nach seiner Anwendung.A very important for the consumer, but it is difficult to quantitatively measurable property of cosmetic products is a certain invigorating and / or smooth skin feel and the suppleness of the skin after its application.
Eine rosige Hautfarbe (wie sie beispielsweise durch den Aufenthalt an der frischen Luft erhältlich ist) wird von den Verbraucherinnen und Verbrauchern als gesund und dementsprechend wünschenswert angesehen, wohingegen ein blasser Teint in der Regel nicht so erwünscht ist. Aufgabe der vorliegenden Erfindung war es, hautpflegende Zubereitungen und Zubereitungen zur Pflege der auf natürliche Weise gealterten Haut zur Verfügung zu stellen, wobei die Zubereitungen das Körperäußere pflegen und verschönern und gleichzeitig Hautfalten reduzieren und Cellulites beseitigen sollen..A rosy skin color (such as is available by staying in the open air) is considered by consumers to be healthy and therefore desirable, whereas a pale complexion is generally not as desirable. It is an object of the present invention to provide skincare preparations and preparations for the care of naturally aged skin, wherein the preparations are intended to nourish and beautify the external appearance of the body and at the same time reduce wrinkles and eliminate cellulites.
Es hat sich überraschenderweise herausgestellt dass eine kosmetische Zubereitung enthaltend (a) einen wässrigen Frucht-Extrakt aus Anis (Pimpinella anis fruit extract), unter dem Handelsnamen Bioxilift bei der Gesellschaft SILAB, St. Viance, Frankreich, erhältlich-und (b) einen oder mehreren Füllstoffen den Nachteilen des Standes der Technik abhilft. Eine solche Zubereitung hat den wesentlichen Vorteil gegenüber Zubereitungen des Standes der Technik, dass durch Zusatz der Füllstoffe eine „sofortige" physikalische Faltenreduktion durch Auffüllen der Falten mit Mikropartikeln stattfindet. Weiterhin wird durch Zusatz der Füllstoffe eine Verfärbung der Emulsion aufgrund der Eigenfarbe des Wirkstoffes bzw. durch Abbauprozesse verringert.It has surprisingly been found that a cosmetic preparation containing (a) an aqueous extract from anise (Pimpinella anis fruit extract), available under the trade name Bioxilift from SILAB, St. Viance, France, and (b) one or more several fillers remedies the disadvantages of the prior art. Such a preparation has the significant advantage over prior art formulations that by adding the fillers an "instantaneous" physical wrinkle reduction by filling the wrinkles with microparticles takes place. reduced by degradation processes.
Darüber hinaus hat eine solche Zubereitung folgende weitere Vorteile: Sie fördert den natürlichen Regenerationsprozeß und Zellstoffwechsel der Haut, aktiviert hauteigene Schutzsysteme und macht die Haut damit widerstandsfähiger gegen Stressfaktoren, wirkt gegen (erste) Zeichen der Hautalterung, indem Linien und Mimikfältchen reduziert, Poren verfeinert und das Hautbild sichtbar gestrafft und geglättet wird, aktiviert tiefenwirksam die hauteigene Produktion von Bestandteilen des Bindegewebes wie Kollagenen, elastischen Fasern und Proteoglykanen (u.a. Hyaluronsäuren), wirkt der Bildung neuer Falten dadurch nachhaltig entgegen, dass Energiedepots/-reserven aufgefüllt und die Haut-/Zellregeneration verbessert wird, trägt zur Verjüngung der inneren Hautstruktur durch Verbesserung der epidermal-dermalen Verzahnung (Papillen) bei, wodurch die Gesichts- und Hautkonturen verfeinert und gestrafft werden, festigt die Haut fühlbar und sichtbar und verbessert die Hautelastizität.In addition, such preparation has the following additional benefits: It promotes the natural regeneration process and cell metabolism of the skin, activates skin protection systems and makes the skin more resistant to stressors, counteracts (first) signs of aging, reducing lines and facial lines, refining pores and The skin is visibly tightened and smoothed, deeply activates the skin's own production of components of connective tissue such as collagens, elastic fibers and proteoglycans (including hyaluronic acids), counteracts the formation of new wrinkles sustainably, the energy depots / reserves filled and the skin / cell regeneration improves, rejuvenates the skin's internal structure by improving the epidermal-dermal (papillae), thereby refining and tightening facial and skin contours, firming the skin palpably and visibly and improving skin elasticity.
Bei Bioxilift handelt es sich um einen wässrigen Frucht-Extrakt aus Anis (Pimpinella anis fruit extract). Der Extrakt weist eine bernsteinartige Farbe auf und hat einen charakteristischen Anis-Geruch.Bioxilift is an aqueous fruit extract from anise (Pimpinella anis fruit extract). The extract has an amber-like color and has a characteristic anise smell.
Der Extrakt ist reich an anorganischen Mineralien wie Natrium- und Magnesium-Ionen, besonders aber an Kalium-Ionen. Die aufgenommenen Spektren liefern keinen Anhaltspunkt für die Identifizierung einzelner Leitstrukturen bzw. Wirkprinzipien. Vielmehr stellen die Spektren „typische" Pflanzenextrakt-Spektren dar.The extract is rich in inorganic minerals such as sodium and magnesium ions, but especially in potassium ions. The recorded spectra do not deliver Clue for the identification of individual lead structures or principles of action. Rather, the spectra represent "typical" plant extract spectra.
Die spezifische Zusammensetzung lautet:The specific composition is:
Dry matter: 40-60 g/l Mineral ashes 11-18 g/l Total protein 12-20 g/l pH 4,5-5,5Dry matter: 40-60 g / l Mineral ashes 11-18 g / l Total protein 12-20 g / l pH 4.5-5.5

Bioxilift wird von der Gesellschaft SILAB, Frankreich angeboten.During production, the aniseed fruits are solubilized in water and hydrolyzed enzymatically. The ratio of raw material to extract is Vz. Soluble and insoluble phases are separated and subsequently filtered or subsequently sterile filtered. Bioxilift is offered by the company SILAB, France.
Füllstoffe im Sinne der vorliegenden Erfindung sind partikuläre Substanzen, die in der Regel keinen Farbeffekt in der kosmetischen Formulierung erzeugen, in der sie eingesetzt werden. Ferner haben erfindungsgemäße Füllstoffe üblicherweise einen niedrigen Brechungsindex und daraus resultierend keine oder eine nur sehr geringe Deckkraft.Fillers in the context of the present invention are particulate substances which as a rule do not produce any color effect in the cosmetic formulation in which they are used. Furthermore, fillers according to the invention usually have a low refractive index and, as a result, no or very little opacity.
Der Stand der Technik kennt eine Reihe von Füllstoffen, welche z. B. als Trägermaterialien bei der Formulierung von Pudern oder als Viskositäts- und Sensorik- Modulatoren in Emulsionen oder wasserfreien Formulierungen dienen. Derartige Füllstoffe werden häufig auch eingesetzt, um mattierende Effekte auf der Haut zu erlangen oder um Sebum zu absorbieren.The prior art knows a number of fillers, which z. B. serve as support materials in the formulation of powders or as viscosity and sensor modulators in emulsions or anhydrous formulations. Such fillers are also often used to obtain matting effects on the skin or to absorb sebum.
Darüber hinaus beeinflußt der Einsatz von Füllstoffen im allgemeinen auch die Verteilbarkeit üblicher Formulierungen auf der Haut sowie die Gleichmäßigkeit eines möglichen Farbeffektes. Die Füllstoffe im Sinne der vorliegenden Erfindung werden vorteilhaft aus der Gruppe der anorganische Füllstoffe gewählt, beispielsweise aus der Gruppe der Silikate.In addition, the use of fillers generally also affects the spreadability of conventional formulations on the skin and the uniformity of a possible color effect. The fillers in the context of the present invention are advantageously selected from the group of inorganic fillers, for example from the group of silicates.
Silikate sind Salze und Ester (Kieselsäureester) der Orthokieselsäure [Si(OH)4] und deren Kondensationsprodukte. Die Silikate sind nicht nur die artenreichste Klasse der Mineralien, sondern auch geologisch und technisch außerordentlich wichtig. Über 80 % der Erdkruste bestehen aus Silikaten.Silicates are salts and esters (silicic acid esters) of orthosilicic acid [Si (OH) 4 ] and their condensation products. The silicates are not only the most species-rich class of minerals, but also extremely important geologically and technically. Over 80% of the earth's crust is made up of silicates.
Vorteilhaft im Sinne der vorliegenden Erfindung sind beispielsweise Schichtsilikate. Schichtsilikate (Phyllosilikate, Blattsilikate) sind (idealerweise) Silikat-Strukturen mit zweidimensional unendlichen Schichten aus [SiO4]4"- Tetraedern, wobei jedes Tetraeder über 3 Brücken-Sauerstoffe mit Nachbar- Tetraedern verbunden ist.For the purposes of the present invention, for example, phyllosilicates are advantageous. Layered silicates (phyllosilicates, leaf silicates) are (ideally) silicate structures with two-dimensionally infinite layers of [SiO 4 ] 4 " tetrahedra, each tetrahedron being connected via 3 bridging oxygens with neighboring tetrahedra.
Chemische Formeln lassen sich für Schichtsilikate nur angenähert aufstellen, da sie ein großes lonenaustausch-Vermögen besitzen und Silicium gegen Aluminium und dieses wiederum gegen Magnesium, Fe2+, Fe3+, Zn und dergleichen ausgetauscht werden kann. Die daraus möglicherweise resultierende negative Ladung der Schichten wird in der Regel durch Kationen, insbesondere durch Na+ und Ca2+ in Zwischenschicht-Positionen ausgeglichen.Chemical formulas can only be approximated for phyllosilicates because they have a large ion exchange capacity and silicon can be exchanged for aluminum and this in turn against magnesium, Fe 2+ , Fe 3+ , Zn and the like. The resulting possibly negative charge of the layers is usually compensated by cations, in particular by Na + and Ca 2+ in interlayer positions.
Schichtsilikate können durch reversible Einlagerung von Wasser (in der 2- bis 7- fachen Menge) und anderen Substanzen wie z. B. Alkoholen, Glykolen und dergleichen mehr aufquellen. Ihre Verwendung als Verdickungsmittel in kosmetischen Mitteln ist dementsprechend an sich bekannt. Allerdings konnte der Stand der Technik nicht den Weg zur vorliegenden Erfindung weisen.Phyllosilicates can be obtained by reversible storage of water (in the 2- to 7-fold amount) and other substances such. As alcohols, glycols and the like swell. Their use as thickeners in cosmetic products is accordingly known per se. However, the prior art could not point the way to the present invention.
Vorteilhafte Schichtsilikate, welche im Sinne der vorliegenden Erfindung eingesetzt werden können, sind beispielsweise solche, deren größte Ausdehnungsrichtung im unmodifizierten und ungequollenen Zustand im Mittel eine Länge von weniger als 10 μm hat. Beispielsweise können die mittleren Ausdehnungen der verwendeten modifizierten Schichtsilikatpartikel bei 1000 nm x 100 nm x 1 nm und darunter liegen. Die effektive Größe der modifizierten Schichtsilikatpartikel in einer kosmetischen oder dermatologischen Formulierung hängt selbstverständlich von der Menge an eingelagerten Substanzen ab.Advantageous phyllosilicates which can be used in the context of the present invention are, for example, those whose largest expansion direction in the unmodified and unswollen state has an average length of less than 10 μm. For example, the mean extents of the modified layered silicate particles used may be 1000 nm × 100 nm × 1 nm and less. The effective size of the modified Of course, layered silicate particles in a cosmetic or dermatological formulation depend on the amount of stored substances.

Nachteilig ist jedoch für derartige Zubereitungen, welche Filmbildner in einer wirksamen (d. h. die Wasserfestigkeit steigernden) Konzentration enthalten, daß sie bei der Anwendung auf der Haut einen klebrigen und schmierigen Eindruck hinterlassen. Neben dem Einfluß der Grundlage ist auch die Bindungsfähigkeit des UV-Filters in oder auf der Haut von großer Bedeutung für die Wasserfestigkeit der Formulierung. Es ist verständlich, daß öllösliche UV-Filter besser an die (lipophile) Oberfläche der Haut gebunden werden bzw. schwerer von dieser abwaschbar sind als wasserlösliche UV-Filter.However, it is disadvantageous for such formulations which contain film formers in an effective (that is to say increase the water resistance) concentration that they leave a sticky and greasy impression when applied to the skin. In addition to the influence of the base, the binding ability of the UV filter in or on the skin is of great importance for the water resistance of the formulation. It is understood that oil-soluble UV filters are better bound to the (lipophilic) surface of the skin or are more difficult to wash off this than water-soluble UV filters.
