SonnenschutzzubereitungenSunscreen preparations
Die vorliegende Erfindung betrifft Sonnenschutzöle, die eine besonders hohe Lichtschutzwirkung und damit einen hohen Lichtschutzfaktor, verbesserte Resorption sowie verbesserte kosmetische Eigenschaften besitzen.The present invention relates to sunscreen oils that have a particularly high sun protection effect and thus a high one Have sun protection factor, improved absorption and improved cosmetic properties.
Der Lichtschutzfaktor eines Lichtschutzmittels gibt an, um wieviel mal länger die Haut, durch dieses Mittel geschützt, der Sonne ausgesetzt werden kann als ohne dessen Anwendung.The sun protection factor of a sun protection agent indicates around how many times longer the skin can be exposed to the sun, protected by this agent, than without its use.
Es ist bekannt, daß Sonnenschutzöle, verglichen mit Emulsionen z.B. Milch, Creme usw., bei gleichem Gehalt an Lichtschutzsubstanzen nur eine sehr schwache Lichtschutzwirkung aufweisen. In der Regel liegen die Werte für die Lichtschutzfaktoren bei Ölen zwischen 1,5 und maximal 3. Diese Tatsache ist überraschend, da innerhalb des Sonnenschutzöles eine völlig gleichmäßige Verteilung der Lichtschutzsubstanz vorliegt« Auch eine Steigerung der Konzentration der Filtersubstanzen bewirkt nur eine unwesentliche Erhöhung der Lichtschutzfaktoren.It is known that, compared with emulsions, e.g. milk, cream, etc., sun protection oils have the same content of light protection substances only have a very weak sun protection effect. As a rule, the values for the sun protection factors are for oils between 1.5 and a maximum of 3. This fact is surprising, since within the sun protection oil one completely Even distribution of the light protection substance is present «Also causes an increase in the concentration of the filter substances only an insignificant increase in the sun protection factors.
Auch die Kombination verschiedener Lichtschutzsubstanzen und die Variation bzw. Kombination verschiedener Ölkomponenten bringt nur eine geringfügige Verbesserung der Lichtschutzwirkung. Also the combination of different light protection substances and the variation or combination of different oil components brings only a slight improvement in the sun protection effect.

Bs wurde nun gefunden, daß Sonnenschutzöle, die Wasser und hydrophile Olkomponenten enthalten, eine "besonders hohe Lichtschutzwirkung, verbesserte Resorption und verbesserte kosmetische Eigenschaften aufweisen. Dabei kann der Wassergehalt mehr oder weniger groß sein, wobei es jedoch wesentlich ist, daß die typischen Ölmerkmale (Aussehen, klare Lösung, Hautgefühl) erhalten werden. Dafür ist der Zusatz der hydrophilen Olkomponenten erforderlich.It has now been found that sun protection oils which contain water and hydrophilic oil components have a "particularly high" Sun protection effect, improved absorption and improved have cosmetic properties. The water content can be more or less high, but it is essential is that the typical oil characteristics (appearance, clear solution, skin feel) are retained. For that is the addition of the hydrophilic oil components required.
Fig. 1 zeigt die Abhängigkeit des Lichtschutzfaktors von der Konzentration der Filtersubstanz bei einem herkömmlichen Sonnenschutzöl im Vergleich zu einem erfindungsgemäßen Sonnenschutzöl. Fig. 1 shows the dependence of the sun protection factor on Concentration of the filter substance in a conventional sun protection oil compared to a sun protection oil according to the invention.
In dieser Fig. 1 ist auf der x-Achse der Filtergehalt in %, auf der y-Achse der Lichtfaktor angegeben. Die punktierte Linie bedeutet ein erfindungsgemäß, die gekreuzte Linie ein herkömmliches Sonnenschutzöl.In this FIG. 1, the filter content is indicated in% on the x-axis and the light factor is indicated on the y-axis. The dotted line means a sun protection oil according to the invention, the crossed line a conventional sun protection oil.
Der Lichtschutzfaktor wird also wesentlich durch den Wassergehalt beeinflußt. Wie stark dieser Einfluß ist, zeigt Fig. 2. Darin ist auf der x-Achse der Wassergehalt in % und auf der y-Achse der Lichtschutzfaktor angegeben; der Filtergehalt ist konstant.The sun protection factor is therefore significantly influenced by the water content. How strong this influence is is shown in FIG. 2. It shows the water content in % on the x-axis and the sun protection factor on the y-axis; the filter content is constant.
Es ist als ausgesprochen überraschend zu bezeichnen, daß die erfindungsgemäßen Sonnenschutzöle Lichtschutzfaktoren größer als 7 erreichen. Sie ermöglichen erstmals, sowohl öllösliche als auch wasserlösliche Lichtschutzfilter zu verwenden.It can be described as extremely surprising that the Sun protection oils according to the invention, sun protection factors are greater than reach 7. For the first time, they make it possible to use both oil-soluble and water-soluble light protection filters.
Dies war um so weniger zu erwarten, als die bisher realisierbaren Lichtschutzfaktoren von Sonnenschutzölen in der Regel für intensive Sonneneinstrahlung nicht ausreichend waren, sodaß zur Erzielung von besserem Schutz andereThis was all the less to be expected as the previously realizable sun protection factors of sun protection oils in the Usually for intense sun exposure were not sufficient, so that to achieve better protection others

Präparate, z.B. Emulsionen oder wässrig-alkoholische Lösungen verwendet werden mußten.Preparations, e.g. emulsions or aqueous-alcoholic solutions, had to be used.
Neben der guten Lichtschutzwirkung der erfindungsgemäßen Sonnenschutzöle zeichnen sich diese Präparate noch durch ihr hervorragendes Eindringvermögen aus, ein kosmetisch und dermatologisch erwünschter Effekt. Ein besseres Eindringen verhindert auch Verluste an Sonnenschutzpräparaten durch Abwischen usw., wie diese bei den bisherigen Ölen bekannt sind. Außerdem lassen sich Flecken in Kleidungsstücken ohne größeren Aufwand durch einfaches Herauswaschen mit kaltem Wasser entfernen.In addition to the good light protection effect of the invention Sun protection oils, these preparations are characterized by their excellent penetration, a cosmetic and dermatologically desirable effect. Better penetration also prevents the loss of sunscreen preparations Wiping, etc., as they are known with the previous oils. In addition, stains in clothing can be avoided Remove greater effort by simply washing it out with cold water.
Als Wirkstoffe kommen praktisch alle in der kosmetischen und pharmazeutischen Industrie üblichen Lichtschutzmittel in Betracht, (siehe G.A.Nowak: "Die kosmetischen Präparate", Verlag für ehem.
