  Verfahren zur Herstellung desinfizierender   Mittel.   



   Die Wirksamkeit eines Desinfiziens hängt keineswegs bloss von der bakteriziden Kraft des dazu verwendeten chemischen Stoffes ab. Sie wird vielmehr in hohem Masse von der Form und den physikalischen Bedingungen, unter welchen der Stoff zur Anwendung gelangt,   beeinflusst.   Vor allem durch die Art des Mittels, in dem er gelöst ist. Dass z. B. sonst sehr wirksame   desinfizientien   in öliger Lösung versagen, hat Robert Koch 
 EMI1.1 
 am besten seine Kraft entfalten kann. 



   Gegenstand dieser Erfindung Ist ein Verfahren zur Herstellung desinfizierender Mittel, bei welchem nicht das Wasser als solches als Lösungsmittel Verwendung findet, sondern die hochviskosen Lösungen sonst indifferenter Stoffe. Es wurde nämlich die überraschende Tatsache festgestellt, dass Desinfizientia in derartigen Schleimen aufgelöst, den Wirkungswert ihrer rein   wässerigen Lösungen übertreffen.   



   Zu den Stoffen, welche in wässeriger Lösung Schleime von der Beschaffenheit bilden. dass sie ein wirkungerhöhendes Medium für desinfizierende chemische Stoffe abgeben. gehören vor allem die Derivate der Laminarsänre. besonders das unter dem   Namen Norgine"   bekannte   Natriumammoniumsalz.   



   Schon ein kurzer orientierender Versuch mit Sublimat und Natriumfluorid zeigte die Überlegenheit der neuen Lösungsmittel gegenüber dem Wasser.   Ausführliche   Versuche mit dem so wichtigen und viel verwendeten Formaldehyd bewiesen dies in xakter Weise.   Die Versuche wurden nach der Kochschen Seidenfadenmethode   mit dem schr widerstandefähigen Staphylococcus pyog. aureus angestellt.

   Aus folgender Tabelle ist der neue Effekt an einigen Beispielen ersichtlich :

  Process for the manufacture of disinfectants.



   The effectiveness of a disinfectant does not depend solely on the bactericidal power of the chemical substance used. Rather, it is largely influenced by the shape and the physical conditions under which the substance is used. Mainly by the type of agent in which it is dissolved. That z. For example, Robert Koch says that otherwise very effective disinfectants fail in oily solutions
 EMI1.1
 can best develop its strength.



   The subject of this invention is a process for the production of disinfecting agents, in which the water as such is not used as a solvent, but the highly viscous solutions of otherwise inert substances. The surprising fact was found that disinfectants, dissolved in such slimes, surpass the effectiveness of their purely aqueous solutions.



   The substances which, in aqueous solution, form slimes of the same nature. that they give off an effect-increasing medium for disinfecting chemical substances. belong mainly the derivatives of laminarsane. especially the sodium ammonium salt known under the name Norgine ".



   Even a brief orientational experiment with sublimate and sodium fluoride showed the superiority of the new solvents over water. Extensive tests with the so important and widely used formaldehyde proved this in an exact way. The experiments were carried out according to the Koch silk thread method with the highly resistant Staphylococcus pyog. aureus employed.

   The following table shows some examples of the new effect:
