Verfahren zum Haltbarmachen von wässerigen Wasserstoffsuperoxyd-Lösungen.
Die wässerigen Lösungen von Wasserstoffsuperoxyd haben bekanntlich die Eigenschaft, sich schnell zu zersetzen. Man hat vorgeschlagen, diese Zersetzung durch Zusatz von Säuren, wie Schwefelsäure, Salzsäure, Phosphorsäure, Essigsäure, Oxalsäure, zu verhindern, ohne jedoch dadurch eine vollständige Konservierung zu erzielen. Ist erst einmal der Zerfall der Wasserstoffsuperoxyd-Moleküle eingetreten, so schreitet derselbe mit zunehmender Zeit sehr n'hn'll fort. so dass binnen kurzem die Lösung kaum mehr als Spuren von Wasserstoff- nupt roxyd enthält. Abgesehen davon, bildet auch der Zusatz von Säuren ein Hindernis für die allgemeine Verwendbarkeit derartiger Wasserstoffsuperoxyd-Lösungen.
Zur Vermeidung dieses Übelstandes hat man der wässerigen Lösung von Wasserstoff- superoxyd kleine Mengen von Azylamiden oder Azylimiden oder auch von Harnsäure hinzu- gefügt und dadurch zweifellos eine bessere Haltbarkeit des Wasserstoffsuperoxyds erreicht.
Es wurde nun gefunden, dass man durch Zusatz von Paraazetylamidophenol die Haltbarkeit \ot < Wasserstoffsuporoxyd-Lösungen noch bedeutend steigern kann und dieser Zusatz bildet den Gegenstand der vorliegenden Erfindung. Der Zusatz von Paraazetylamidophenol besitzt den grossen Vorteil, dal3 gleichzeitig mit der konservierende Wirkung dem Wasserstoff-

für die Zahnpflege und Kosmetik besonders geeignet sind.
Auch gegenüber dem zur Kon- servierung von Wasserstoffsuperoxyd benutzten Eikonogen, welches das Natriumsalz einer Amidonaphtolsufosäure darstellt und welches in seiner Wirkung dem Paraazetylamidophenol am nachsten kommt, besitzt das letztere den Vorzug, dass es die Lösung von Wasserstoff- superoxd nicht färbt, wie es das Eikonogen tut.

Process for the preservation of aqueous hydrogen peroxide solutions.
It is well known that aqueous solutions of hydrogen peroxide have the property of rapidly decomposing. It has been proposed to prevent this decomposition by adding acids, such as sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid, oxalic acid, without, however, achieving complete conservation. Once the disintegration of the hydrogen peroxide molecules has occurred, it progresses very n'hn'll with increasing time. so that within a short time the solution contains little more than traces of hydrogen oxide. Apart from this, the addition of acids also forms an obstacle to the general usability of such hydrogen peroxide solutions.
To avoid this inconvenience, small amounts of acylamides or azylimides, or even uric acid, have been added to the aqueous solution of hydrogen superoxide, and this has undoubtedly made the hydrogen peroxide more durable.
It has now been found that by adding paraacetylamidophenol the shelf life of hydrogen peroxide solutions can still be increased significantly, and this addition forms the subject of the present invention. The addition of paraacetylamidophenol has the great advantage that, at the same time as the preservative effect, the hydrogen

are particularly suitable for dental care and cosmetics.
Compared to the egg-conogen used for the preservation of hydrogen peroxide, which is the sodium salt of an amidonaphthol sulfonic acid and which in its action comes closest to that of para-acetylamidophenol, the latter has the advantage that it does not color the solution of hydrogen superoxide, as does the eikonogen does.
