Description
Verfahren zur Herstellung trocken haltbarer kosmetischer und pharmazeutischer Zubereitungen in Pulverform Bei der Herstellung von pulverförmigen Gemischen und Zubereitungen, wie Zahnpulvern u. dgl., denen man hygroskopische Rhodansalze und zugleich ätherische öle zusetzen will, besteht die Schwierigkeit, solche Gemische in den trockenen Zustand zu überführen oder im trockenen Zustande zu erhalten, da einerseits durch die wasseranziehenden Eigenschaften der Rhodansalze allmählich das ganze Pulver durchfeuchtet wird und andererseits durch die Wirkung der Feuchtigkeit die Bindung der zugesetzten ätherischen Öle an die Präparate aufgehoben wird. Die so aufgenommene Feuchtigkeit vermindert zudem die Streufähigkeit solcher Pulvergemische oder hebt sie ganz auf und löst unter Umständen vorzeitig Reaktionen aus. die erst im Augenblick ihrer Verwendung eintreten sollen.Process for the production of dry-shelf cosmetic and pharmaceutical products Preparations in powder form In the manufacture of powder mixtures and Preparations such as tooth powders and the like, which are hygroscopic rhodan salts and If you want to add essential oils at the same time, there is a difficulty in creating such mixtures to transfer to the dry state or to maintain it in the dry state, there on the one hand by the water-attracting properties of the rhodan salts gradually the whole powder is moistened and on the other hand by the action of moisture the binding of the added essential oils to the preparations is broken. the Moisture absorbed in this way also reduces the throwing power of such powder mixtures or cancels them completely and may trigger premature reactions. the first should occur at the moment of their use.
Die Herstellung ätherische Öle enthaltender pulverförmiger Gemische und Zubereitungen für die Zahnpflege und Reinigung unter Verwendung von hygroskopischen Rhodansalzen ist zwar aus der britischen Patentschrift 2o 897 vom Jahre 1914 bekannt geworden. Diese Gemische sind aber aus den obenerwähnten Gründen nicht haltbar.The production of powdered mixtures and preparations containing essential oils for dental care and cleaning using hygroscopic rhodan salts is known from British patent specification 2o 897 from 1914. However, these mixtures are not stable for the reasons mentioned above.
Es hat sich nun überraschenderweise gezeigt, daß die Verwendung der hygroskopischen Rhodansalze zur Herstellung derartiger Mischungen und Zubereitungen ohne weiteres möglich wird, sofern man sie mit Terpin durchmengt. Auf diese Weise kann erreicht werden, daß nicht nur das aus der Luft angezogene Wasser gebunden wird, sondern daB auch die ätherischen öle fixiert werden. Das Terpin geht dabei ganz oder teilweise in das beständige und trockene Terpinhydrat über. Wenn man beispielsweise zu einem rhodansalzhaltigen Pulvergemisch, das neben ätherischen Ölen noch Säurebestandteile, wie Weinsäure, Borsäure ü. dgl., enthält, Terpin zusetzt, verhindert man nicht nur eine vorzeitige Entwicklung von Rhodanwasserstoffsäure, sondern erhöht auch die Löslichkeit der Rhodansalze durch die Bindung der ätherischen Öle an das Terpin ganz bedeutend.It has now surprisingly been shown that the use of the hygroscopic rhodan salts for the production of such mixtures and preparations becomes possible without further ado, provided that it is mixed with terpine. In this way it can be achieved that not only the water drawn from the air is bound but that the essential oils are also fixed. The Terpin goes with it wholly or partially into the stable and dry terpin hydrate. For example, if you to a powder mixture containing rhodium salts, which in addition to essential oils also contains acid components, like tartaric acid, boric acid, etc. Like., contains, adds terpine, you not only prevent it a premature development of hydrofluoric acid, but also increases the Solubility of the rhodan salts due to the binding of the essential oils to the terpine very significant.
Andererseits. kann auch Terpinhydrat zur Herstellung der vorgenannten Zubereitungen Verwendung finden, wenn man es im Gemisch mit den anderen Bestandteilen durch Erhitzen entwässert, da sich solche Gemische und Zubereitungen nach dieser Behandlung als ebenso haltbar erweisen wie die obengenannten.On the other hand. can also terpin hydrate for the production of the aforementioned Preparations are used when they are mixed with the other ingredients dehydrated by heating, as such mixtures and preparations according to this Treatment prove to be as durable as the above.
Durch das Fixierungsvermögen des Terpins für ätherische öle wird also ermöglicht, Präparate, die Rhodansalze oder andere hygroskopische Salze neben ätherischen Ölen enthalten, in leicht verarbeitungsfähiger Trockenform herzustellen und gleichzeitig trocken haltbar zu machen.The terpin's ability to fix essential oils means that allows preparations containing rhodan salts or other hygroscopic salts in addition to essential ones Contain oils, to be produced in an easily processable dry form and at the same time to keep dry.
