Description
Lichtschutzmittel Gegenstand der Erfindung ist ein Lichtschutzmittel, das in einer Grundlage von Alkohol, Fett, Öl, Paraffin o.dgl. Anthranilsäureverbindungen enthält.Light stabilizers The subject of the invention is a light stabilizer, that in a basis of alcohol, fat, oil, paraffin or the like. Anthranilic acid compounds contains.
Die als Lichtschutzmittel bekannten Amino-und substituierten Aminoorthobenzoesäuren haben /einen so weitgreifenden Absorptionshereich, daß davon auch die langwelligen ultravioletten Strahlen, die gerade für die Pigmentbildungen der Haut ohne Erythembildung von höchster Bedeutung sind, erfaßt werden. Ähnlich verhält sich das ebenfalls als Lichtschutzmittel bekannte Menthylanthranilat sowie das auch schon hierfür vorgeschlagene Cyclohexylanthranilat, das außerdem auch noch sehr ausgeprägt riecht. Die Alkohole der monocyclischen Terpene, wie insbesondere das Menthol und in verstärktem Maße auch die Anthranilsäure, haben eine ausgeprägte hautreizende Wirkung, die bei einem Sonnenschutzmittel naturgemäß sehr unerwünscht ist. die Reizwirkung der Alkoholkomponente ist in den Estern zwar abgeschwächt oder variiert, erreicht jedoch noch immer einen beträchtlichten Grad. The amino and substituted amino orthobenzoic acids known as light stabilizers have / such a far-reaching absorption range that the long-wave ultraviolet rays, which are responsible for the pigmentation of the skin without erythema are of paramount importance. This also behaves similarly as Menthyl anthranilate known from light stabilizers and the one already proposed for this Cyclohexyl anthranilate, which also has a very distinctive smell. The alcohols the monocyclic terpenes, such as menthol in particular, and to a greater extent also the anthranilic acid, have a pronounced skin-irritating effect Sunscreen is naturally very undesirable. the irritant effect of the alcohol component is weakened or varied in the esters, but still reaches one considerable degree.
Diese Nachteile werden bei dem Lichtschutzmittel nach der Erfindung vermieden. These disadvantages become apparent in the light stabilizer according to the invention avoided.
Es wurde gefunden, daß die Anthranilsäureester der Alkohole der bicyclischen Terpengruppe, besonders das Bornylanthranilat bzw.It has been found that the anthranilic acid esters of the alcohols are the bicyclic Terpene group, especially bornyl anthranilate or
Isobornylanthranilat oder Bornylmethylanthranilat bzw. Isobornylmethylanthranilat oder Mischungen dieser Anthranilate, gegebenenfalls unter Zusatz anderer Schutzmittel in einer für die Wirkung ausreichenden Menge, die ultravioletten Strahlen günstiger absorbieren und zum Unterschiled gegen die meisten Anthranilsäureester der Alkohole der monocyciischen Terpengruppe, obwohl sie in chemischer Beziehung wesentlich davon abweichen, auch vorteilhaftere physiologische@Eigenschaften aufweisen.Isobornyl anthranilate or bornyl methyl anthranilate or isobornyl methyl anthranilate or mixtures of these anthranilates, optionally with the addition of other protective agents in an amount sufficient for the effect, the ultraviolet rays more favorable absorb and to subdivide against most anthranilic acid esters of alcohols the monocyclic terpene group, although in chemical relation it is essentially different differ, also have more advantageous physiological properties.
Sie besitzen -einen- schwachen, nicht unangenehmen Geruch und sind in Alkoholen, Fetten, fetten Ölen, Paraffinen, Kohlenwasserstoffen löslich. Das ultraviolette Spektrum wird besonders im Gebiet von 300 µµ und darunter stark absorbiert, wodurch die Bildung eines Sonnenbranderythems verhindert wird. They have - a - weak, not unpleasant odor and are Soluble in alcohols, fats, fatty oils, paraffins, hydrocarbons. That ultraviolet spectrum is particularly strongly absorbed in the area of 300 µµ and below, thereby preventing the formation of a sunburn erythema.
Bereits 3 bis 6% Bornylanthranilat, Isobornylanthranilat oder Fenchylanthranilat mit Fetten, fetten Ölen, Paraffinölen, Vaseline, Wachs-Öl-Mischungen, Lanoline, Cetylalkohol u. dgl. gemischt haben eine ausreichende abschirmende Wirkung. Die natürliche Hautbräunung wird nicht vermindert, sondern gefördert. Already 3 to 6% bornyl anthranilate, isobornyl anthranilate or fenchyl anthranilate with fats, fatty oils, paraffin oils, vaseline, wax-oil mixtures, lanolins, Cetyl alcohol and the like mixed have a sufficient shielding effect. the natural skin tanning is not reduced, but promoted.
Bornylanthranilat ist ein im Vakuum unzersetzt siedender Körper, der gut kristallisiert. Die Kristalle zeigen Fluoreszenz, desgleichen die Lösungen in Alkohol, fetten Ölen u. dgl. Bornyl anthranilate is a body that boils without decomposition in a vacuum, which crystallizes well. The crystals show fluorescence, as do the solutions in alcohol, fatty oils, etc.
Bornylanthranilat oder das sehr ähnliche Isobornylanthranilat hat den wesentlichen Vorzug, die Haut nicht zu reizen oder zu verfärbein. An Stelle der Antbranilsäure können auch Alkylanthranilsäuren, z. B. Methylanthranilsäure, treten. Es ist für die Wirkung gleichgültig, welche Modifikation der Alkohole man wählt. Bornyl anthranilate or the very similar isobornyl anthranilate the major benefit of not irritating or discoloring the skin. Instead of the antranilic acid can also include alkyl anthranilic acids, e.g. B. methylanthranilic acid, step. It does not matter what modification of the alcohols one has for the effect chooses.
