Description
Verfahren zur Herstellung eines für therapeutische Zwecke geeigneten, gegenüber Seifen oder seifenähnlichen Stoffen stabilen Selensulfid-Präparates Es ist bereits bekannt, Selensulfid zur Behandlung der Seborrhoe äußerlich anzuwenden. Die Applikation erfolgt vorzugsweise in Form von Präparaten, die Seifen oder seifenartige Stoffe enthalten. Die seifenhaltigen Selensulfid-Präparate werden als Haarwäsche angewendet, wobei der selensulfidhaltige Schaum für einige Minuten mit der zu behandelnden Kopfhaut in Berührung bleibt und dann mit Wasser abgespült wird. Für die Wirksamkeit ist es besonders wichtig, daß das Selensulfid unzersetzt und in kolloidaler Form vorliegt. Derartige Selensulfild-Präparate sind in Form von Suspensionen im Handel. Process for the preparation of a suitable for therapeutic purposes, Selenium sulfide preparation which is stable to soaps or soap-like substances Es It is already known that selenium sulfide can be used externally for the treatment of seborrhea. The application is preferably carried out in the form of preparations that are soap or soap-like Contain substances. The soap-containing selenium sulfide preparations are used as a hair wash applied, the selenium sulfide-containing foam with the to be treated for a few minutes The scalp is left in contact and then rinsed with water. For effectiveness It is particularly important that the selenium sulfide is undecomposed and in colloidal form is present. Such selenium sulfide preparations are commercially available in the form of suspensions.
Wegen der Neigung des in Suspension enthaltenen Selensulfids zur Teilchenvergröberung und Ausflokkung sowie infolge der Instabilität des Selensnlfids sind die Präparate nur beschränkt lagerfähig und müssen laut Anweisung vor Licht und Wärme geschützt werden. Darüber hinaus besitzt Selensulfid bekanntlich eine große Toxizität, der für die handelsüblichen Präparate infolge ihres hohen Gehalts an 5 elensulfid eine erhöhte Bedeutung beizumessen ist.Because of the tendency of the selenium sulfide contained in suspension to coarsen the particles and flocculation as well as the instability of the selenium sulfide are the preparations Can only be stored for a limited time and must be protected from light and heat according to the instructions will. In addition, selenium sulfide is known to have great toxicity one for the commercially available preparations due to their high content of 5 elene sulfide increased importance is to be attached.
Es wurde nun überraschenderweise ein Verfahren gefunden, nach dem ein für therapeutische Zwecke geeignetes, gegenüber Seifen oder seifenähnlichen Stoffen stabiles, kolloidales Selensulfid-Präparat erhalten wird, indem Selensulfid in Gegenwart eines von Fettalkylresten freien hydrophilen Kolloids gefällt, die entstehende Suspension neutralisiert und einer Zerstäubungstrocknung unterworfen wird, wobei die Suspension gegebenenfalls alkalisch reagierende Stoffe, wie Natriumhydrogencarbonat oder Borax und/oder Füllstoffe, wie Natriumsulfat, und in an sich bekannter Weise Seifen oder seifenartige Stoffe enthalten kann. It has now surprisingly been found a method according to which one suitable for therapeutic purposes, compared to soaps or similar to soaps Substances stable, colloidal selenium sulphide preparation is obtained by adding selenium sulphide in the presence of a hydrophilic colloid free of fatty alkyl radicals, the resulting suspension neutralized and subjected to spray drying is, the suspension optionally alkaline substances such as sodium hydrogen carbonate or borax and / or fillers, such as sodium sulfate, and in a manner known per se May contain soaps or soap-like substances.
Als geeignete hy drophi 1 e Kolloide werden. beispielsweise Dextrin, Gummiarabikum, Carboxycellulose, Pektin, Methylcellulose oder Celluloseglykolat verwendet. Suitable hy drophi 1 e colloids are used. for example dextrin, Gum arabic, carboxycellulose, pectin, methyl cellulose or cellulose glycolate used.
Nach dem erfindungsgemäßen Verfahren werden stabile, in bezug auf Selensulfid hochdisperse Präparate erhalten, in denen sich das Selensulfid auch bei vorübergehendem Erhitzen auf Temperaturen von über 1000 C überraschenderweise nicht zersetzt. According to the method according to the invention are stable, with respect to Selenium sulfide highly dispersed preparations are obtained, in which the selenium sulfide is also with temporary heating to temperatures of over 1000 C surprisingly not decomposed.
Ein solches Präparat stellt, wenn der für die Wirkung wichtige kolloidale Charakter des Selensulfids erhalten lileibt, elinen technischen Fortschritt dar. Das kolloidale Selensulfid in sehr verdünnter Lösung ist zwar einige Tage beständig, koaguliert dann aber heim Eintrocknen und ist aus diesem Grunde als solches nicht herzustellen. Dies ist erfindungsgemäß nur in Gegenwart eines hydrophilen keine Fettalkylreste enthaltenden I(oilloids möglich. Such a preparation represents if the colloidal one is important for the effect The character of selenium sulphide remains unchanged and represents pure technical progress. The colloidal selenium sulfide in a very dilute solution is stable for a few days, But then it coagulates when it dries out and is therefore not as such to manufacture. According to the invention, this is only none in the presence of a hydrophilic one I (oilloids containing fatty alkyl radicals possible.
In Gmelin, »Handbuch der organischen Chemie«, 1949, Bd. »SelenB«, S. 175, Zeile37ff.. heißt es zur Darstellung von Selensulfidsolen, daß der Zusatz einer verdünnten Gummi arabikumlösung die Haltbarkeit des Sols nicht nur unwesentlich verlängert, d. h. durch den nachträglichen Zusatz des Schutzkolloids zum ausgefällten Selensulfid wird eine Haltharkeit, wie sie nach dem erfindungsgemäßen Verfahren erzielt wird, nicht erreicht. Entsprechen,d dieser Literaturstelle hergestellte Sole liegen in Lösungen von 0,1 g SeS2 in 250 cm3 H20 vor. Sie koagulieren bereits bei längerem Stehen, indem Wasser aus der Lösung verdunstet. In Gmelin, "Handbook of Organic Chemistry", 1949, Vol. "SelenB", P. 175, line 37ff .. it says for Representation of selenium sulfide sols that the addition a diluted gum arabic solution not only negligibly affects the shelf life of the sol extended, d. H. by the subsequent addition of the protective colloid to the precipitated Selenium sulfide has a shelf life such as that obtained by the method according to the invention is achieved, not achieved. Corresponding to this reference produced Brine is in solutions of 0.1 g SeS2 in 250 cm3 H20. You are already coagulating when standing for a long time, as water evaporates from the solution.
Ausführungsbeispiel Zur Herstellung des Präparats werden drei Lösungen benötigt: Lösung A: 232 g Natriumsulfid (Na2S 9 9 H2O) werden mit so viel Wasser gelöst, daß man 500 ccm Lösung erhält. Embodiment Three solutions are used to produce the preparation required: Solution A: 232 g sodium sulfide (Na2S 9 9 H2O) are mixed with as much water dissolved so that 500 cc of solution is obtained.
Lösung B: 48,5 g SeS2 werden mit so viel Wasser gelöst, daß man 500 ccm Lösung erhält.Solution B: 48.5 g SeS2 are dissolved with enough water that 500 ccm solution received.
Lösung C: 97 g Schwefelsäure und 100 g Dextrin werden in 900 ccm Wasser gelöst.Solution C: 97 g of sulfuric acid and 100 g of dextrin are dissolved in 900 cc of water solved.
Man läßt jetzt die Lösungen A und B mit gleicher Geschwindigkeit innerhalb von etwa 21/2 Stunden unter gleichzeitiger mechanischer Rührung zu Lösung C fließen, wobei man die Zuführung der zuzugebenden Lösung unterhalb des Flüssigkeitsspiegels von Lösung C vornimmt. Solutions A and B are now left at the same speed to solution within about 21/2 hours with simultaneous mechanical stirring C flow, with the addition of the solution to be added below the liquid level of solution C.
Die hierbei entstehende gelbe Suspension wird anschließend durch Zugabe von Schwefelsäure oder Natronlauge genau neutralisiert und im Zerstäubungstrockner getrocknet. Das hierbei anfallende orangefarI>ene Pulver enthält etwa 20°/o SeS2. Es wird mit so viel einer Mischung von zwei Teilen handelsüblichem Fettalkoholsulfat und einem Teil pulverisiertem Borax versetzt, daß das Endprodukt 2t/o Selensulfid enthält. The resulting yellow suspension is then through Addition of sulfuric acid or caustic soda exactly neutralized and in the spray dryer dried. The resulting orange powder contains about 20% SeS2. It is made with as much a mixture of two parts of commercially available fatty alcohol sulfate and a part of powdered borax added that the end product 2t / o selenium sulfide contains.
