Description
<B>Verfahren zur Herstellung eines</B> Jodpräparates. Im Hauptpatent ist ein Verfahren zur Herstellung eines Jodpräparates mit geringer Giftigkeit beschrieben, zu dessen Herstellung ein wasserlösliches, polymeres N-Vinyl-pyrro- lidon mit dem Mindest-KWert 10 mit. einer höchstens 10 /o des Polymergewichtes aus machenden Menge freien Jodes in innige Be rührung gebracht wird.
Es wurde nün gefunden, dass sich der artige Jodpräparate auch mit. höheren Jod- gehalten herstellen lassen, die ebenfalls kein freies Jod enthalten und deshalb reizfrei sind, sofern der Jodgehalt 35 0/a des Polymerge- wichtes nicht überschreitet.
Die vorliegende Erfindung betrifft. somit ein Verfahren zur Herstellung eines Jodprä- parates mit. geringer Giftigkeit, das dadurch gekennzeichnet. ist, dass man wasserlösliches polymeres N-Vinyl-pyrrolidon, das mindestens den K-Wert 10 aufweist, mit einer zwischen 10 und 35 0/a des Polymergewichtes betragen den Menge freien Jodes in innige Berührung bringt.
Die Herstellung des erfindungsgemässen Präparates kann, wie im Hauptpatent be schrieben, durch Zusatz einer Polyvinylpyrro- lidonlösung zu einer Jodlösung, durch inniges Verreiben von festem Jod mit Polyvinyjpyrro- lidon oder durch Suspension des trockenen Polyvinylpyrrolidons in einer Jodlöstuig, deren Lösungsmittel das Polymer nicht ziu lösen vermag, erfolgen.
Es scheint aber, dass die durch trockenes Verreiben .der Komponen ten hergestellten Präparate nicht alles Jod in Form einer Verbindung enthalten, wenn Jod- gehalte über etwa 20 % vorliegen, so däss diese Herstellungsweise nur für jodärmere Präparate anwendbar ist.
Das erhaltene Produkt ist ein braunrotes, in Wasser klar lösliches Pulver, das nicht nach Jod riecht. Es findet, vorzugsweise in ge löster Form, vor allem zur örtlichen Desin fektion Verwendung, eignet sich aber auch zur pa-renteralen Verwendung und für alige- mein sanitarisehe Zwecke.
<I>Beispiel:</I> 100 g Polyvinylpyrrolidon mit dem K-Wert 30 und 18 g Jod wurden in einer Kugelmühle bis zur vollständigen Homogenität vermahlen. Das erhaltene braune Pulver löste sich glatt und klar in Wasser auf. Als 10 o/oige Lösung auf die Haut aufgetragen, übte das Präparat keine Reizwirkung aus.
<B> Process for the production of </B> an iodine preparation. The main patent describes a process for the production of an iodine preparation with low toxicity, for the production of which a water-soluble, polymeric N-vinyl-pyrrolidone with a minimum K value of 10 is used. a maximum of 10 / o of the polymer weight is brought into intimate contact with a sufficient amount of free iodine.
It has now been found that the like iodine preparations also work with. produce higher iodine contents, which also contain no free iodine and are therefore free of irritation, provided the iodine content does not exceed 35% of the polymer weight.
The present invention relates to. thus a process for the production of an iodine preparation with. low toxicity, which is characterized. is that water-soluble polymeric N-vinyl-pyrrolidone, which has at least the K value 10, is brought into intimate contact with an amount of free iodine amounting to between 10 and 35% of the polymer weight.
The preparation according to the invention can, as described in the main patent, by adding a polyvinylpyrrolidone solution to an iodine solution, by thoroughly triturating solid iodine with polyvinylpyrrolidone or by suspending the dry polyvinylpyrrolidone in an iodine solution whose solvent does not dissolve the polymer able to take place.
It seems, however, that the preparations made by dry rubbing the components do not contain all iodine in the form of a compound if the iodine content is above about 20%, so that this method of production can only be used for preparations with a lower iodine content.
The product obtained is a brown-red powder that is clearly soluble in water and does not smell of iodine. It is used, preferably in dissolved form, above all for local disinfection, but is also suitable for parenteral use and general sanitary purposes.
<I> Example: </I> 100 g polyvinylpyrrolidone with a K value of 30 and 18 g iodine were ground in a ball mill until completely homogeneous. The brown powder obtained dissolved smoothly and clearly in water. Applied to the skin as a 10% solution, the preparation had no irritative effect.
