Description

Verfahren zur Herstellung eines Desinfektionsmittels. Formaldehydlösung besitzt vorzügliche desinfizierende Eigenschaften. Ihrer Anwendung als keimtötendes Mittel auf Schleimbäute bei der Mund-, Rachen- und Scheidenbehandlung steht aber ihre außerordentliche Gerb- und Reizwirkung hinderlich entgegen. Eine Ab- schwächung dieser nachteiligen Wirkungen des Formaldehyds könnte durch Zusatz von Gelatine erreicht werden. Bringt man aber Formaldehyd mit Gelatine zusammen, so erhält man eine unlösliche Verbindung, die zur Herstellung keimtötender Lösungen nicht geeignet ist.Process for the production of a disinfectant. Formaldehyde solution has excellent disinfecting properties. However, their use as a germicidal agent on mucous membranes in the treatment of the mouth, throat and vagina is hindered by their extraordinary tanning and irritating effects. A weakening of these adverse effects of formaldehyde could be achieved by the addition of gelatin. However, if formaldehyde is combined with gelatin, an insoluble compound is obtained which is not suitable for the production of germicidal solutions.

Es ist nun gefunden worden, daß eine solche Lösung hergestellt werden kann, wenn man Formaldehyd auf Gelatinelösung von bestimmter Konzentration bei Gegenwart von Rhodanalkalien oder Rhodanerdalkalien zur Einwirkung bringt.It has now been found that such a solution can be made can if you have formaldehyde on gelatin solution of certain concentration in the presence of Rhodanalkalien or Rhodanerdalkalien brings to action.

Die Gelatinelösung darf nicht zu konzentriert sein, weil sonst die beabsichtigte Wirkung nicht erreicht wird und trotz der Anwesenheit von Rhodansalz unter Umständen ein allmähliches Unlöslichwerden eintritt. Für den hier in Frage kommenden Zweck ist dieses jedoch ohne Bedeutung, weil es für denselben nicht auf die Anwendung einer besonders stark konzentrierten Gelatinelösung ankommt, sondern vielmehr darauf, daß die Lösung solche in ihrer gerbenden und Reizwirkung abgeschwächte Mengen Formaldehyd enthält, welche ausreichen, um eine gründliche resinfektion der Schleimhäute durchzuführen. Lieses ist aber bei den Mengenverhältnissen der Fall, in welchen sich die durch Zusatz eines Rhodansalzes in Lösung gebrachte Formaldehyd-Gelatineverbindung herstellen läßt. Die Stärke der Gelatinelösung, welche nicht überschritten werden darf, läßt sich durch Versuche leicht ermitteln.The gelatin solution must not be too concentrated, otherwise the intended effect is not achieved and despite the presence of rhodan salt it may gradually become insoluble. For the one in question here However, this is irrelevant to the coming purpose, because it does not arise for the same the use of a particularly highly concentrated gelatin solution matters, but rather, it is important that the solution weakened such tanning and irritating effects Contains quantities of formaldehyde sufficient to allow thorough reinfection of the Perform mucous membranes. But this is the case with the proportions in which the formaldehyde-gelatin compound dissolved by the addition of a rhodan salt can be produced. The strength of the gelatin solution, which should not be exceeded can easily be determined by experiments.

Die auf die beschriebene Weise erhaltene Lösung besitzt die starke keimtötende #Nirkung des Formaldehyds, ohne seine nachteiligen Eigenschaften aufzuweisen.The solution obtained in the manner described has the strongest one germicidal action of formaldehyde without showing its disadvantageous properties.

Ausführungsbeispiel.-4 g Gelatine werden in 26 g Wasser unter Zusatz von io g Rhodankalium gelöst; zu dieser Lösung werden 6o g einer Lösung hinzugefügt, welche 40 9 Wasser; io g Rhodankalium und io g Formaldehyd enthält. Das Ganze wird alsdann mit ioo g Wasser verdünnt.Exemplary embodiment.-4 g of gelatin are dissolved in 26 g of water with the addition of 10 g of potassium rhodan; to this solution are 6o g of a solution was added containing 40 9 of water; Contains 10 g of potassium rhodium and 10 g of formaldehyde. The whole is then diluted with 100 g of water.
