Description
Lichtschutzmittel An Lichtschutzmittel wird die Forderung gestellt, daß sie eine geeignete Absorption für die erythemerzeugenden Strahlen aufweisen und auf der Haut gut verträglich sind. Auf die Hautverträglichkeit muß dabei besonderer Wert gelegt werden, da im allgemeinen große Teile der gesamten Hautfläche und auch weniger abgehärtete und dadurch besonders empfindliche Hautpartien mit dem Lichtschutzmittel bedeckt werden.Light stabilizers The requirement is made on light stabilizers, that they have adequate absorption for the erythema-producing rays and are well tolerated by the skin. Special attention must be paid to skin tolerance Value should be placed, as in general, large parts of the entire skin area and also Less hardened and therefore particularly sensitive skin areas with the sunscreen to be covered.
Es stehen bisher viele Substanzen zur Verfügung, die zwar eine entsprechende Absorption aufweisen, aber der Forderung nach einer guten Hautverträglichkeit nicht voll entsprechen. There are so far many substances available, although a corresponding Have absorption, but not the requirement for good skin tolerance fully comply.
Überraschenderweise wurde nun gefunden, daß gewisse Substanzen, die eine nahe Verwandschaft zu körpereigenen Stoffen, insbesondere zu Eiweißbausteinen mit aromatischen oder heterocyclischen Resten aufweisen, neben einer sehr guten Absorption eine besonders gute Hautverträglichkeit besitzen. So eignen sich z. B. die p-Oxyzimtsäure bzw. ihr Methyläther und dessen Derivate wegen ihrer nahen Verwandtschaft zu Tyrosin als Lichtschutzmittel; sie werden auch bereits hierzu verwendet, ohne daß allerdings diese Zusammenhänge erkannt worden sind. Surprisingly, it has now been found that certain substances that a close relationship to the body's own substances, in particular to protein building blocks with aromatic or heterocyclic radicals, in addition to a very good one Absorption have a particularly good skin tolerance. So are z. B. p-oxycinnamic acid or its methyl ether and its derivatives because of their close relationship to tyrosine as a light protection agent; they are already used for this purpose, without that, however, these connections have been recognized.
Wesentlich verbessert wird die Lichtschutzwirkung, wenn man den substituierten Phenylrest in diesen Säuren durch heterocyclische Reste, z. B. durch den Benzimidazol- oder insbesondere durch den Furanrest ersetzt. Ferner können auch Äther, Ester, Amide und Salze dieser Säuren benutzt werden. The sunscreen effect is significantly improved if the substituted Phenyl radical in these acids by heterocyclic radicals, e.g. B. by the benzimidazole or in particular replaced by the furan residue. Furthermore, ethers, esters, Amides and salts of these acids can be used.
