Description

Strahlenschutzmittel Für den Schutz der mensdhl@ichen Haut gegen die schädlichen Wirkungen von Strahlen sind zahlreiche Mittel beschrieben. Durch das deutsche Patent 676103 wurden erstmals die Zusammenhänge zwischen Erythembildung und Pigmentbildung in der menschlichen Haut geklärt und die Mindestforderungen an ein wirksames Lichtschutzmittel aufgestellt. Darüber hinaus wurden in der Patentschrift Substanzen aufgeführt, welche diese Forderungen in jeder Hinsicht erfüllen.Radiation protection agent For the protection of the human skin against the Numerous means have been described for the harmful effects of radiation. By the German patent 676103 was the first time the connections between erythema formation and pigment formation in human skin clarified and the minimum requirements an effective light stabilizer set up. In addition, in the patent Substances listed that meet these requirements in every respect.

Diese Substanzen haben aber den Nachteil, daB sie sich nicht genügend oder auch gar nicht in Grundlagen einarbeiten lassen, die als Treibmittel für einen »Spray« Verwendung finden, wie z. B. Vinyldhlorid USW. However, these substances have the disadvantage that they cannot be incorporated sufficiently, or not at all, into the fundamentals that are used as propellants for a "spray", e.g. B. Vinyldhlorid ETC.

Es wurde nun gefunden, daß man beispielsweise die in der deutschen Patentschrift 676103 erwähnte 2-Phenyl-benzimidazol-5-sulfosäure auch in den Grundlagen für einen Spray in den für einen sicheren Hautlichtschutz erforderlichen Konzentrationen in Lösung bringen kann, wenn man als Salzbildner Triäthanolamin verwendet.It has now been found that, for example, those in the German Patent specification 676103 mentioned 2-phenyl-benzimidazole-5-sulfonic acid also in the basics for a spray in the concentrations required for safe skin light protection can bring into solution if triethanolamine is used as a salt former.

Diese Erkenntnis war um so überraschender, als die normalen anorganischen Salze der 2-Phenyl-benzimidazol-S-sulfosäure, wie beispielsweise das Ammonsalz, das Na-Salz und das K-Salz in dem Spray-Medium völlig urilöslich sind. Das gleiche Verhalten zeigten auch beispielsweise das Sulfami.d, das Diaäthylsulfamid und das Sulfanilid.This finding was all the more surprising than the normal inorganic ones Salts of 2-phenyl-benzimidazole-S-sulfonic acid, such as the ammonium salt, the Na salt and the K salt are completely soluble in urine in the spray medium. The same Behavior also showed, for example, the Sulfami.d, the Diaäthylsulfamid and the Sulfanilide.

Die Verwendung der vorstehend erwähnten Sulfosäure als Triäthanolaminsalz bietet gegenüber den üblicherweise verwendeten öllöslichen Lichtschutzgrundlagen - wie einschlägige Versuche ergeben haben - den Vorteil, daB ;sie auf der Epidermis fixiert wird und somit in ihrer Absorptionsfähigkeit nicht durch Resorption vermindert wird. Damit ist ein länger wirksamer Schutz gegen die erythemwirksamen Strahlen gewährleistet, ohne d-aB die erwünschten pigmentbildenden Strahlern in ihrer Wirkung geschwächt werden.The use of the above-mentioned sulfonic acid as a triethanolamine salt offers over the commonly used oil-soluble light protection bases - as relevant experiments have shown - the advantage of being on the epidermis is fixed and thus its absorption capacity is not reduced by resorption will. This is a longer effective protection against the erythema-causing rays guaranteed, without d-aB, the desired pigment-forming emitters in their effect be weakened.

Für die Herstellung eines sicheren Schutzfilmes auf der menschlichen Haut genügt ein Gehalt von 4 bis 6% der 2-Phenyl-benzimidaz.o1-5-sulfosäure als Triäthamolaminsalz in der Treibstofflösung, der auch Duftstoffe oder Verbindungen zugesetzt werden können.For the production of a safe protective film on the human A content of 4 to 6% of 2-phenyl-benzimidaz.o1-5-sulfonic acid is sufficient for skin Triethamolamine salt in the fuel solution, which also contains fragrances or compounds can be added.
