Die wäßrigen Lösungen des Wasserstoffsuperoxyds 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 j edoch · dadurch eine vollständige Konservierung zu erzielen. Ist erst einmal der Zerfall des WasserstoffsuperoxydmölekülsThe aqueous solutions of hydrogen peroxide are known to have the property to decompose quickly. It has been proposed to reduce this decomposition by adding To prevent acids such as sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid, oxalic acid, but without thereby achieving complete preservation. Is only once the disintegration of the hydrogen peroxide oil molecule
ίο eingetreten, so schreitet er mit der Zeit sehrίο entered, he progresses very much with the time
. schnell fort, so daß binnen kurzem die Lösung kaum mehr als Spuren von Wasserstoffsuperoxyd enthält. Abgesehen, ;davon bildet auch der Zusatz von Säuren ein Hindernis. quickly, so that within a short time the solution contains little more than traces of hydrogen peroxide. Apart; the addition of acids is also an obstacle
IS für die allgemeine Verwendung derartiger Wasserstoffsuperoxydlösungen.IS for general use of such Hydrogen peroxide solutions.
.Zur Vermeidung dieses Übelstandes hat man der wäßrigen Lösung von Wasserstoffsuperoxyd kleine Mengen von Acylamiden oder Acylimiden, oder auch von Harnsäure zugefügt und dadurch zweifellos eine bessere Haltbarkeit des Wasserstoffsuperoxyds erreicht. Es wurde nun gefunden, daß man durch Zusatz von Paraacetylamidophenol die HaItbarkeit von Wasserstoffsuperoxydlösungen noch bedeutend steigern kann. Der Zusatz von Paraacetylamidophenol besitzt den großen Vorteil, daß zugleich mit der konservierenden Wirkung dem Wasserstoffsuperoxyd eine erhöhte desinfizierende Eigenschaft verliehen wird, wodurch diese Lösungen für die Zahnpflege und Kosmetik besonders geeignet sind. Gegenüber dem zur Konservierung von Wasserstoffsuperoxyd benutzten Eikonogen (Natriumsalz einer Amidonaphtolsulfosäure), welches in seiner Wirkung dem Paraacetylamidophenol am nächsten kommt, besitzt das letztere den Vorzug, daß es die Lösung von Wasserstoffsuperoxyd nicht färbt, wie es das Eikonogen tut. .To avoid this inconvenience one has the aqueous solution of hydrogen peroxide small amounts of acylamides or acylimides, or uric acid added and thereby undoubtedly achieved a better shelf life of the hydrogen peroxide. It has now been found that the stability can be achieved by adding paraacetylamidophenol of hydrogen peroxide solutions can still increase significantly. The addition of paraacetylamidophenol owns the great The advantage that at the same time as the preservative effect of the hydrogen peroxide is increased disinfectant property is bestowed, making these solutions for dental care and cosmetics are particularly suitable. Compared to that for the preservation of hydrogen peroxide used Eikonogen (sodium salt of an amidonaphthol sulfonic acid), which has the effect of paraacetylamidophenol closest, the latter has the advantage of being the solution of hydrogen peroxide does not stain like the egg does. .
Vergleichsversuche, welche mit einigen wichtigen bekannten Mitteln zur Haltbarmachung von Wasserstoffsuperoxydlösungen vorgenommen wurden, haben unzweifelhaft die erhöhte Wirkungsweise des Paraacetylamidophenols erwiesen.Comparative tests, which with some important known means of preservation of hydrogen peroxide solutions undoubtedly have the increased Proven mode of action of Paraacetylamidophenol.
In der Regel genügt ein Zusatz von 1 g Paraacetylamidophenol zu 11 10 volumprozentiger , Wasserstoffsuperoxydlösung.As a rule, an addition of 1 g of paraacetylamidophenol to 11 10 percent by volume is sufficient , Hydrogen peroxide solution.
