Verfahren zur Haltbarmachung von Mischungen aus trockenen Säuren oder sauren Salzen und kristallwasserhaltigen Perboraten
Zum Desinfizieren der Mundhöhle benutzt man meist solche Stoffe, welche durch die Berührung mit den Schleimhäuten und dem Speichel Sauerstoff abgeben, wie Wasserstoffsuperoxyd, Peroxyde, Perborate. Indem man die Perborate unmittelbar vor dem Gebrauch mit einer Säure zersetzt, erhält man eine Lösung von Wasserstoffsuperoxyd. Es würden deshalb Tabletten sehr bequem in der Anwendung sein, welche gleichzeitig Perborat und eine trockene Säure, z. B. Weinsäure oder Zitronensäure, enthalten und in Wasser gelöst Wasserstoffsuperoxyd ergeben. Solche Mischungen halten sich jedoch nicht, indem das Kristallwasser eine Zersetzung schon nach kurzer Zeit bewirkt.
Nach vorliegender Erfindung können jedoch solche Tabletten dadurch haltbar gemacht werden, dass man dem Gemisch von Perhorat und trockener Säure oder sauren Saison einen
EMI1.1
dann diese Mischungen zu einer einzigen, so erhält man ein haltbares Pulver, aus dem man ebenso haltbare Tabletten'pressen kans. 1) lese Tatsache ist um so überraschender, als Natriumbikarbonat, also ein saures Satz, nicht als ein indifferentes Mittel gegen Perborat und Weinsäure gelten kann. Bringt man die Tabletten nnt Wasser zusammen, so erhält man augenblicklich eine alkalische Wasserstoffsuperoxydlösung, während Perborat bikarbonattabletten ohne Weinsäurezusatz nur langsam in Lösung gehen.

Process for preserving mixtures of dry acids or acidic salts and perborates containing water of crystallization
To disinfect the oral cavity, substances are usually used which release oxygen through contact with the mucous membranes and saliva, such as hydrogen peroxide, peroxides, perborates. By decomposing the perborate with an acid immediately before use, a solution of hydrogen peroxide is obtained. It would therefore be very convenient to use tablets containing perborate and a dry acid, e.g. B. tartaric acid or citric acid, and dissolved in water give hydrogen peroxide. However, such mixtures do not last because the water of crystallization causes decomposition after a short time.
According to the present invention, however, such tablets can be made durable by adding a mixture of perhorate and dry acid or acid season
EMI1.1
Then these mixtures become a single one, so a durable powder is obtained from which one can press tablets that are just as durable. 1) This fact is all the more surprising since sodium bicarbonate, that is, an acidic proposition, cannot be regarded as an indifferent remedy for perborate and tartaric acid. If the tablets are brought together in water, an alkaline hydrogen peroxide solution is obtained immediately, whereas perborate bicarbonate tablets without the addition of tartaric acid dissolve only slowly.
