Description

Lichtschutzmittel Zusatz zum Patent 919505 In dem Hauptpatent 9I9 505 ist eine Lichtschutzsalbe beschrieben, die einen Gehalt an halogeniertem Benzyl-a-pyridyldimethylaminoäthylamin bzw. dessen Salzen enthält, und zwar gegebenenfalls unter Zusatz von p-Aminosalicylsäure, wobei insbesondere die Bromverbindung hervorgehoben wurde, und die Lichtschutzsalbe auch noch geringe Mengen eines Deckfarbstoffes enthalten kann. Light stabilizer additive to patent 919505 In the main patent 9I9 505 describes a light protection ointment which contains halogenated benzyl-a-pyridyldimethylaminoethylamine or contains its salts, possibly with the addition of p-aminosalicylic acid, with particular emphasis on the bromine compound and the light protection ointment may also contain small amounts of an opaque dye.

Es hat sich nun gezeigt, daß an Stelle einer Salbe auch mit bestem Erfolg ein Produkt von mehr fließenden Eigenschaften oder überhaupt ein flüssiges Produkt zur Verwendung gelangt. Zur Herstellung des Lichtschutzmittels kann man wäßrige oder ölige Lösungen, gegebenenfalls in Gegenwart eines Lösungsvermittlers, benutzen. Beispielsweise verwendet man eine wäßrige 20/0ige Lösung des substituierten Benzyla-pyridyldimethylaminoäthylamins, der man genügend wasserlösliche Polymerisate zufügt, z. B. wasserlösliche Polyvinylalkohole in Mengen von beispielsweise IO bis 20°/o, um ähnlich wie bei der Salbe die Möglichkeit eines gleichmäßigen Auftrages zu gewährleisten. Zur Erhöhung der Schutzwirkung kann der Amingehalt gegebenenfalls auch noch erhöht werden. It has now been shown that instead of an ointment also with the best Success a product of more flowing properties or a liquid at all Product has come to use. For the preparation of the light stabilizer one can aqueous or oily solutions, optionally in the presence of a solubilizer, use. For example, an aqueous 20/0 solution of the substituted one is used Benzyla-pyridyldimethylaminoäthylamins, which one has enough water-soluble polymers adds, e.g. B. water-soluble polyvinyl alcohols in amounts of, for example, IO to 20%, in order to ensure the possibility of an even application, similar to the ointment to ensure. The amine content can optionally be used to increase the protective effect can also be increased.

Die Lichtschutzmittel können anstatt einer der genannten schützenden Verbindungen auch Gemische von zwei oder mehreren derselben enthalten. The light stabilizers can instead of one of the mentioned protective Compounds also contain mixtures of two or more of the same.

An Stelle der in dem Hauptpatent genannten halogensubstituierten Produkte mit Halogen in p-Stellung können auch solche Produkte verwendet werden, bei denen die Halogensubstitution in o- oder m-Stellung durchgeführt ist. Den genannten Verbindungen oder deren Salzen kann gegebenenfalls ein Zusatz von p-Aminosalicylsäure gemacht werden. Instead of the halogen-substituted ones mentioned in the main patent Products with halogen in the p-position can also use such products will, in which the halogen substitution is carried out in the o- or m-position. The one mentioned Compounds or their salts can optionally contain an addition of p-aminosalicylic acid be made.

Als substituierendes Halogen hat sich insbesondere Brom bewährt. Dem Lichtschutzmittel können auch noch geringe Mengen eines Deckfarbstoffes zugefügt werden.Bromine in particular has proven useful as a substituting halogen. To the Light stabilizers can also be added in small amounts of an opaque dye will.
