Abstract
Kosmetische Zubereitung, enthaltend a) Styrol/Acrylat-Copolymere und b) ein oder mehrere UV-Lichtschutzfilter.Cosmetic preparation containing a) styrene / acrylate copolymers and b) one or more UV light protection filters.
Description
Die vorliegende Erfindung betrifft Styrol/Acrylat-Copolymere in kosmetischen Zubereitungen.The The present invention relates to styrene / acrylate copolymers in cosmetic Preparations.
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 "has been unbroken for years people are exposing their skin to sunlight, as this causes a pigmentation in the sense of melanin formation. However, the ultraviolet radiation of sunlight also has one damaging effect on the skin. Besides the acute injury (Sunburn) occur long-term damage as an increased Risk of developing skin cancer in case of excessive Irradiation with light from the UVB range (wavelength: 280-320 nm). The excessive Influence of UVB and UVA radiation (wavelength: 320-400 nm) leads to a weakening the elastic and collagen fibers of the connective tissue. this leads to to numerous phototoxic and photoallergic reactions and causes premature aging of the skin.
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 in the form of positive lists such as Appendix 7 of the German Cosmetics Regulation summarized.
Eine besondere Form von kosmetischen Sonnenschutzmitteln stellen die so genannten wasserfesten Sonnenschutzmittel dar.A special form of cosmetic sunscreen provide the so-called waterproof sunscreen.
Die meisten Sonnenschutzmittel werden in Wassernähe oder bei sportlicher Betätigung (Schwitzen) angewendet, weshalb der Wasserfestigkeit solcher Formulierungen eine besondere Bedeutung beizumessen ist. Ein wasserfestes Sonnenschutzmittel schützt den Anwender nicht nur nach dem Baden, sondern bewahrt ihn auch während des Badens vor einem Sonnenbrand.The Most sunscreens are used near or near water exercise (sweating) applied, which is why the water resistance of such formulations is of particular importance is to be measured. A waterproof sunscreen protects The user not only after bathing, but also preserves him while bathing before a sunburn.
Um hohe Lichtschutzfaktoren bei gleichzeitiger sehr guter Wasserfestigkeit zu erreichen, sind W/O-Formulierungen in der Regel von Vorteil. Allerdings weisen W/O-Emulsionen häufig unbefriedigende kosmetische Eigenschaften auf: Bei der Anwendung können sie auf der Haut einen fettigen, glänzenden und zum Teil klebrigen Eindruck hinterlassen und sich – insbesondere auf behaarter Haut – schwierig verteilen lassen.Around high sun protection factors with at the same time very good water resistance To achieve W / O formulations are usually beneficial. However, W / O emulsions are often unsatisfactory cosmetic properties on: In the application can They on the skin a greasy, shiny and in part leave a sticky impression and yourself - especially on hairy skin - difficult to spread.
Viskose O/W-Emulsionen und dünnflüssige Sprays hingegen wirken weniger fettend auf der Haut, sind eher mattierend und ziehen schnell in die Haut ein. Sie werden vom Verbraucher im allgemeinen als leichter und kosmetisch eleganter als W/O-Emulsionen empfunden. Da Wasser die äußere Phase ist, sind O/W-Emulsionen gewöhnlich allerdings nur bedingt wasserfest.viscose O / W emulsions and low-viscosity sprays, however have less greasy on the skin, are rather matte and pull quickly into the skin. They are from the consumer in general perceived as lighter and more cosmetically elegant than W / O emulsions. Since water is the outer phase, O / W emulsions are usually only partially waterproof.
Um die Wasserfestigkeit kosmetischer Sonnenschutzmittel zu verbessern, werden den Zubereitungen so genannte Filmbildner zugesetzt. Nach dem Stand der Technik eignen sich hierzu z. B. Polyurethane (z. B. die Avalure®-Typen von Goodrich), Dimethicone Copolyol Polyacrylate (Silsoft Surface® von der Witco Organo Silicones Group), PVP/VA (VA = Vinylacetat) Copolymer (Luviscol VA 64 Powder der BASF), C20-40 Carbonsäure mit Polyethylen (Performacid 350 von der Fa. New Phase Technologies) sowie Filmbildner aus der Gruppe der Polymere auf Basis von Polyvinylpyrrolidon (PVP): In order to improve the water resistance of cosmetic sunscreen agents, so-called film formers are added to the preparations. According to the prior art, this z. As polyurethanes (eg. As the Avalure ® grades from Goodrich), dimethicone copolyol polyacrylates (Surface Silsoft ® from Witco Organo Silicones Group), PVP / VA (VA = vinyl acetate) copolymer (Luviscol VA 64 Powder from BASF), C 20-40 carboxylic acid with polyethylene (Performacid 350 from New Phase Technologies) and film formers from the group of polymers based on polyvinylpyrrolidone (PVP):
Besonders bevorzugt werden Copolymere des Polyvinylpyrrolidons eingesetzt, beispielsweise das PVP Hexadecen Copolymer und das PVP Eicosen Copolymer, welche unter den Handelsbezeichnungen Antaron V216 und Antaron V220 bei der GAF Chemicals Cooperation er hältlich sind, sowie das Tricontayl PVP und dergleichen mehr.Especially Copolymers of polyvinylpyrrolidone are preferably used, for example, the PVP hexadecene copolymer and the PVP eicosene copolymer, which under the trade names Antaron V216 and Antaron V220 at the GAF Chemicals Cooperation, as well as the Tricontayl PVP and the like more.
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. Darüber hinaus ist die Wasserfestigkeit und Schweißfestigkeit der Zubereitungen des Standes der Technik nur begrenzt. Aus diesem Grunde werden derartige Produkte auch regelmäßig mit dem Hinweis versehen, nach dem Baden erneut Sonnenschutzmittel auf die Haut aufzutragen. Für den Verbraucher hat dies den Nachteil, dass er, um einen effektiven UV-Schutz zu erhalten, einen erhöhten Verbrauch an Sonnenschutzmitteln hat. Für die Umwelt, insbesondere für das Badegewässer, besteht der Nachteil eines erhöhten Eintrags an Sonnenschutzmittel, was aus Umweltschutzgründen nicht immer erwünscht ist.A disadvantage, however, is for such preparations containing film former in an effective (ie increasing the water resistance) concentration that they leave a sticky and greasy impression when applied to the skin. In addition, the water resistance and weld strength of the prior art formulations is limited. For this reason, such products are also regularly provided with the note to apply sunscreen on the skin after bathing again. For the consumer, this has the disadvantage that it, in order to obtain an effective UV protection, increased Consumption of sunscreen has. For the environment, especially for the bathing water, there is the disadvantage of increased entry of sunscreen, which is not always desirable for environmental reasons.
Es war daher die Aufgabe der vorliegenden Erfindung, ein vor den UV-Strahlen der Sonne schützendes Kosmetikum zu entwickeln, welches eine gegenüber den Produkten des Standes der Technik erhöhte Wasserfestigkeit und Schweißfestigkeit aufweist.It was therefore the object of the present invention, one before the UV rays to develop the sun protective cosmetic which a higher water resistance compared to the products of the prior art and welding strength.
Es war ferner die Aufgabe der vorliegenden Erfindung, ein wasserfestes Sonnenschutzmittel zu entwickeln, dass in gegenüber dem Stand der Technik in reduzierter Menge an Filmbildner (bei gleichem Lichtschutzfaktor des Sonnenschutzmittels und bei gleichem Sonnenschutz für die Haut) eingesetzt werden kann.It was also the object of the present invention, a waterproof Sunscreen to develop that in relation to the State of the art in a reduced amount of film former (with the same Sun protection factor of the sunscreen and with the same sun protection for the skin).
Darüber hinaus war es die Aufgabe der vorliegenden Erfindung, ein wasserfestes Sonnenschutzmittel zu entwickeln, welches eine angenehme kosmetische Sensorik (nicht schmierig, leicht auf der Haut zu verteilen) aufweist.About that In addition, it was the object of the present invention, a waterproof To develop sunscreen, which is a pleasant cosmetic Sensory (not greasy, easy to distribute on the skin).
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.Next the influence of the basis is also the ability to bind of the UV filter in or on the skin is of great importance for the water resistance of the formulation. It is understandable, that oil-soluble UV filters adhere better to the (lipophilic) Surface of the skin become bound or heavier of this are washable as water-soluble UV filters.
Eine weitere Aufgabe der Erfindung war es daher, auf einfache und preiswerte Weise zu Zubereitungen (insbesondere zu O/W-Formulierungen) zu gelangen, welche sich durch eine gute Wasserfestigkeit auszeichnen. Insbesondere sollten Zubereitungen gefunden werden, welche einen hohen Gehalt an wasserlöslichen UV-Filtern haben und dennoch eine sehr gute Wasserfestigkeit zeigen.A Another object of the invention was therefore to simple and inexpensive To go to preparations (in particular to O / W formulations), which are characterized by a good water resistance. Especially Preparations should be found which are high in content have water-soluble UV filters and yet a very show good water resistance.

Vergleichsversuch: Erhöhung der Wasserfestigkeit von SonnenschutzproduktenComparative experiment: increase in Water resistance of sunscreen products
Vergleichsversuche Styrene-Acrylate Copolymer gegen VP/Hexadecene Copolymer und filmbildnerfreie FormulierungComparative Experiments Styrene-Acrylate Copolymer against VP / hexadecene copolymer and film former-free formulation
In Vergleichsversuchen zur Fähigkeit verschiedener Polymere, die Wasserfestigkeit von Sonnenschutzprodukten zu erhöhen, wurden die einzelnen Polymere in der gleichen Konzentration in das Testsystem eingearbeitet und dessen Wasserfestigkeit in-vitro bestimmt.In Comparative Experiments on the Ability of Different Polymers increase the water resistance of sunscreen products, The individual polymers were in the same concentration in the Test system incorporated and determines its water resistance in vitro.
Als
Testrezeptur diente:
Entsprechend der Lipophilie wurde VP/Hexadecene Copolymer in die Fettphase und die Styrene/Acrylate Copolymer Dispersion in die Wasserphase eingearbeitet.Corresponding The lipophilicity was VP / hexadecene copolymer in the fatty phase and incorporated the styrene / acrylate copolymer dispersion in the water phase.
Die eingesetzte Polymerkonzentration betrug in beiden Fällen 10% aktives Polymer (VP/Hexadecene Copolymer lag als Reinsubstanz, Styrene/Acrylate Copolymer als Dispersion mit 46% Feststoffanteil vor.)The used polymer concentration was in both cases 10% active polymer (VP / hexadecene copolymer was pure, Styrene / acrylate copolymer as a dispersion with 46% solids content in front.)
Der
in-vitro Wasserfestigkeitstest wurde wie folgt durchgeführt:
Als
Substrat für den Test dient ein künstliches Hautmodell
namens Vitro Skin, das von der IMS Testing Group vertrieben wird.
Es soll sich um eine Matrix handeln, die sowohl Proteine als auch
Lipide enthält und hinsichtlich ihrer Topographie, pH-Wert
und Oberflächenspannung der menschlichen Haut ähnelt.The in vitro water resistance test was carried out as follows:
The substrate for the test is an artificial skin model called Vitro Skin, which is distributed by the IMS Testing Group. It should be a matrix that contains both proteins and lipids and resembles the topography, pH and surface tension of human skin.
Das Substrat wird in kleine Stücke von 2,8 cm × 3,8 cm Größe geschnitten und anschließend der Herstelleranweisung entsprechend über 16–18 Stunden bei einer genau eingestellten Luftfeuchtigkeit in einer Feuchtigkeitskammer gelagert.The Substrate is broken into small pieces of 2.8 cm x 3.8 cm size cut and then according to the manufacturer's instructions over 16-18 Hours at a precisely set humidity in a humidity chamber stored.
Die so vorbereiteten Substratstücke werden mit 20 mg Formulierung gleichmäßig eingecremt und die Stücke in handelsübliche Diarahmen eingespannt.The thus prepared substrate pieces are formulated with 20 mg evenly creamed and the pieces clamped in standard slide frames.
Nach 20 Minuten, in denen die Formulierung koalesziert (in der Feuchtigkeitskammer), werden an 5 verschiedenen Stellen auf einem VitroSkin Stück Absorptionsspektren im Wellenlängenbereich von 280–420 nm aufgenommen und aus ihnen ein Mittelwertspektrum errechnet. Als Referenz dient dabei hydrierte aber ansonsten unbehandelte VitroSkin.To 20 minutes in which the formulation coalesces (in the humidity chamber), be at 5 different places on a VitroSkin piece Absorption spectra in the wavelength range of 280-420 nm recorded and calculated from them a mean value spectrum. When Reference is hydrogenated but otherwise untreated VitroSkin.
Es schließt sich ein 80 minütiges Bad in einem 2L Becherglas mit leichter Wasserbewegung (Blattrührer mit 50 rpm) an. Die Proben werden eine halbe Stunde lang bei normaler Raumfeuchtigkeit und anschließend für 2 Stunden in der Feuchtigkeitskammer gelagert, bevor erneut Absorptionsspektren aufgenommen werden (gleiche Orte und gleicher Wellenlängenbereich wie die ersten Spektren).It joins a 80 minute bath in a 2L Beaker with gentle water movement (blade stirrer with 50 rpm). Samples become normal for half an hour Room humidity and then for 2 hours stored in the humidity chamber before re-absorption spectra be recorded (same places and same wavelength range like the first spectra).
Zur Auswertung werden die Integrale der jeweiligen Mittelwertspektren einer Probe vor und nach dem Badevorgang, so dass sich die in-vitro Wasserfestigkeit wie folgt ergibt: For evaluation, the integrals of the respective mean value spectra of a sample before and after the bathing process, so that the in vitro water resistance results as follows:
In diesem Modell erreicht die filmbildnerfreie Testformulierung eine in-vitro Wasserfestigkeit von 38,05%.In In this model, the film former free test formulation reaches a in vitro water resistance of 38.05%.
Der zur Zeit in vielen Sonnenschutzrezepturen standardmäßig eingesetzte Filmbildner VP/Hexadecene Copolymer erzielte bei einer Einsatzkonzentration von 10% einen Wasserfestigkeitswert von 48,69%, während mit dem Styrene/Acrylate Copolymer „Joncryl 1532" 53,61% und dem Styrene/Acrylate Copolymer „Joncryl ECO2124" 83,13% erzielt werden konnten.Of the currently in many sunscreen formulations by default used film former VP / hexadecene copolymer scored at one Use concentration of 10%, a water resistance value of 48.69%, while with the styrene / acrylate copolymer "Joncryl 1532" 53.61% and the styrene / acrylate copolymer "Joncryl ECO2124" 83,13% could be achieved.
