Patentiert im Deutschen Reiche vom 25. Januar 1906 ab.Patented in the German Empire on January 25, 1906.
Die Erfindung bezieht sich auf ein Verfahren zur Isolierung von luft- und feuchtigkeitsempfindlichen medizinischen oder anderen Substanzen durch Umhüllung mit dem im Handel unter der Bezeichnung »Ma'isin« erhältlichen Eiweißstoffe.The invention relates to a method for the insulation of air and moisture sensitive medicinal or other substances by coating with the commercially available under the name "Ma'isin" available proteins.
Dieser nach dem in der Patentschrift 14421753 beschriebenen Verfahren aus Mais gewonnene Eiweißstoff weist Eigenschaften auf, die ihn zu einem hervorragenden Einhüllungsmittel machen, insbesondere für solche Stoffe, Welche im Darm zur Einwirkung kommen sollen und durch den Magen dahin gelangen. Maiisin widersteht dem sauren Magensaft, löst sich dagegen leicht im alkalischen Darmsaft und wird infolge seiner Proteidnatur durch Assimilation verwertet. Es ist vollkommen neutral, unlöslich in Wasser, daher unempfindlich gegen einen Wassergehalt der eingehüllten Substanz und gegen die Luftfeuchtigkeit, auch unempfindlich gegen Sonnenlicht.This protein obtained from maize according to the method described in patent specification 144 217 53 has properties that make it an excellent enveloping agent, especially for those substances that are supposed to act in the intestine and get there through the stomach. Maiisin resists acidic gastric juice, but dissolves easily in the alkaline intestinal juice and, due to its protein nature, is utilized by assimilation. It is completely neutral, insoluble in water, therefore insensitive to the water content of the enveloped substance and to air humidity, also insensitive to sunlight.
Es gibt mit Alkohol eine konzentrierte, viskose Lösung, wodurch die Bildung selbstThere is a concentrated, viscous solution with alcohol, which causes the formation itself
häutchenfeiner Überzüge bei größter Gleichmäßigkeit ermöglicht wird. Die Überzüge sind schmiegsam und nicht zur Brüchigkeit geneigt.skin-fine coatings is made possible with the greatest uniformity. The coatings are pliable and not prone to breakage.
Dazu gesellt sich ein geringer Preis.In addition, there is a low price.
Durch diese Eigenschaften unterscheidet sich Ma'isin ganz wesentlich von den üblichen Umhüllungsstoffen. So ist die Gelatine magenlöslich und kann nicht dazu dienen, Stoffe in den Darmtraktus zu bringen. Keratin, welches ebenfalls nur im Darmsaft löslich ist, gibt einen spröden und wasserempfindlichen Überzug, der einer wasserundurchlässigen Unterlage bedarf und außerdem schwierig herzustellen ist. Salol (Salicylsäurephenylester) läßt wegen seiner chemischen Beschaffenheit nur eine beschränkte Anwendung zu und ist zudem nicht ganz unempfindlich gegen Magensaft; es ist keine indifferente Substanz und muß kühl und vor der Sonne geschützt aufbewahrt werden. Schellack kann nur als äußerster Notbehelf erachtet werden.These properties make ma'isin very different from the usual Wrapping materials. So the gelatin is stomach-soluble and cannot be used to put substances in to bring the intestinal tract. Keratin, which is also only soluble in the intestinal juice, gives a brittle and water-sensitive coating, that of a water-impermeable one Requires pad and is also difficult to manufacture. Salol (salicylic acid phenyl ester) Due to its chemical nature, it can only be used to a limited extent and is also not completely insensitive to gastric juice; it is not an indifferent substance and must be kept cool and protected from the sun. Shellac can only be used as extreme makeshift.
Die Benutzung des Ma'isins für den vorliegenden Zweck erfolgt in der üblichen Weise, d. h. man kann die zu schützende Substanz in Form eines Pulvers von beliebiger Korngröße mit einer konzentrierten Maisinlösung mischen, wobei diese zugleich als BindemittelThe ma'isin is used for the present purpose in the usual way, d. H. the substance to be protected can be in the form of a powder of any grain size Mix with a concentrated maisin solution, using this as a binding agent
