Die in der US 5 807 641 beschriebenen Gläser finden insbesondere als Glasur Verwendung. From US 5 807 641 is an antibacterial and antifungal Glass composition for ceramic products such as Sanitary materials have become known, the materials being a Can include silver halide. Those described in US 5,807,641 Glasses are used in particular as a glaze.
Aus der JP-A-91146436 ist ein mikrobizides Glas zur Behandlung von Wasser oder zur Vernichtung von Algen und Mikroorganismen in Wasser bekanntgeworden. Das Glas gemäß der JP-A-91146436 umfaßt Halogenide als Rohmaterial. JP-A-91146436 discloses a microbicidal glass for the treatment of water or to destroy algae and microorganisms in water known. The glass according to JP-A-91146436 comprises halides as raw material.
Aufgabe der Erfindung ist es, ein antimikrobiell, entzündungshemmend und desinfizierend wirkendes Glas bereitzustellen, das selbst antimikrobielle und entzündungshemmende Wirkung besitzt und durch Zusatz von Jodid im Glas dessen desinfizierende Wirkung synergetisch nutzt. The object of the invention is an antimicrobial, anti-inflammatory and To provide disinfectant glass that is itself antimicrobial and has anti-inflammatory effects and by adding iodide in the glass uses its disinfectant effect synergistically.
Die Aufgabe wird durch jodidhaltige Glaszusammensetzungen gemäß Anspruch 1 gelöst. The task is accomplished through iodide-containing glass compositions Claim 1 solved.
Jod bzw. Jodid besitzt eine antimikrobielle Wirkung, die im medizinischen Bereich schon seit langer Zeit ausgenutzt wird. Eine Jod-Tinktur ist eine klare, braunrote Flüssigkeit, die aus 2,5 Tl. Jod, 2,5 Tl. Kaliumjodid, 28,5 Tl. Wasser sowie 66,5 Tl. Alkohol (90%) besteht. Iodine or iodide has an antimicrobial effect, which in medical Area has been used for a long time. An iodine tincture is a clear, brown-red liquid consisting of 2.5 parts of iodine, 2.5 parts of potassium iodide, 28.5 parts of water and 66.5 parts alcohol (90%).
Durch geringe Gehalte an Jodid im Glas eignet sich diese Erfindung hervorragend zur Nahrungsergänzung. Höher mit Jodid dotierte Gläser zeigen eine deutliche antimikrobielle Wirkung sowie desinfizierende und entzündungshemmende bzw. wundheilende Eigenschaften, wobei diese Wirkung synergistisch die Einzelwirkungen des Glases sowie der Jodid-Ionen übersteigt. This invention is suitable due to the low levels of iodide in the glass excellent for nutritional supplements. Glasses higher doped with iodide show a clear antimicrobial effect as well as disinfectant and anti-inflammatory or wound healing properties, these The individual effects of glass and iodide ions work synergistically exceeds.
Das Glas enthält SiO2 als Netzwerkbildner zw. 30-80 Gew.-%. Bei niedrigeren Konzentrationen nimmt die hydrolytische Beständigkeit stark ab, so daß das Mahlen in wässrigen Medien nicht mehr ohne signifikante Auflösung des Glases gewährleistet ist. Bei höheren Werten kann die Kristallisationsstabilität abnehmen und die Verarbeitungstemperatur wird deutlich erhöht, so daß sich die Schmelz- und Heißformgebungseigenschaften verschlechtern. The glass contains SiO 2 as a network former between 30-80% by weight. At lower concentrations, the hydrolytic resistance decreases significantly, so that grinding in aqueous media can no longer be guaranteed without significant dissolution of the glass. At higher values, the crystallization stability can decrease and the processing temperature is increased significantly, so that the melting and hot forming properties deteriorate.
Na2O wird als Flußmittel beim Schmelzen des Glases eingesetzt. Bei Gesamtkonzentrationen kleiner 5% wird das Schmelzverhalten negativ beeinflußt. Außerdem wirkt der notwendige Mechanismus des Ionenaustausches nicht mehr hinreichend, um eine antibakterielle Wirkung zu erzielen. Bei höheren Konzentrationen als 40 Gew.-% ist eine Verschlechterung der chemischen Resistenz bzw. hydrolytischen Beständigkeit insbesondere in Verbindung einer Abnahme des SiO2-Anteils zu beobachten. Na 2 O is used as a flux when melting the glass. The melting behavior is negatively influenced at total concentrations of less than 5%. In addition, the necessary mechanism of ion exchange no longer works sufficiently to achieve an antibacterial effect. At concentrations higher than 40% by weight, a deterioration in the chemical resistance or hydrolytic resistance can be observed, in particular in connection with a decrease in the SiO 2 content.
P2O5 ist ein Netzwerkbildner und kann die Kristallisationsstabilität erhöhen. Die Konzentrationen sollten nicht oberhalb von 15 Gew.-% liegen, da ansonsten die chemische Beständigkeit des Silicatglases zu stark abnimmt. P2O5 verbessert die Oberflächenreaktivität der Gläser. P 2 O 5 is a network former and can increase crystallization stability. The concentrations should not be above 15% by weight, otherwise the chemical resistance of the silicate glass will decrease too much. P 2 O 5 improves the surface reactivity of the glasses.
B2O3 ist ein Netzwerkbildner und erhöht die chemische Beständigkeit. Durch Variation der Gehalte kann die Reaktivität des Glases und damit die Wirkung gesteuert werden. B 2 O 3 is a network builder and increases the chemical resistance. The reactivity of the glass and thus the effect can be controlled by varying the contents.
CaO verbessert die chemische Beständigkeit insbesondere im leicht alkalischen Bereich und ist daher notwendig, um eine Auflösung des Glases in wässrigen Medien zu verhindern. Außerdem trägt es zum Ionenaustausch gegen H+ bei. CaO improves the chemical resistance especially in the light alkaline range and is therefore necessary to dissolve the glass to prevent in aqueous media. It also contributes to ion exchange against H + at.
MgO verbessert die chemische Beständigkeit insbesondere im leicht alkalischen Bereich und ist daher notwendig, um eine Auflösung des Glases in wässrigen Medien zu verhindern. Weiterhin trägt es zum Ionenaustausch mit H+ bei. MgO improves the chemical resistance especially in the light alkaline range and is therefore necessary to dissolve the glass to prevent in aqueous media. It also contributes to ion exchange with H + at.
K2O- und Li2O-Zugaben begünstigen die Austauschbarkeit des Natriums bzw. Kalium, und Lithium kann selber gegen H+-Ionen ausgetauscht werden. K 2 O and Li 2 O additions favor the interchangeability of sodium and potassium, and lithium itself can be exchanged for H + ions.
Die Menge an Al2O3 kann zur Erhöhung der Kristallisationsstabilität bis zu maximal 10 Gew.-% hinzugegeben werden. The amount of Al 2 O 3 can be added up to a maximum of 10% by weight to increase the crystallization stability.
Fluorid kann zur Erzielung einer synergistischen Verstärkung der Wirkung mit Jodid zugesetzt werden. Fluoride can be used to achieve a synergistic effect enhancement Iodide can be added.
Das erfindungsgemäße Glas kann in großtechnischen Maßstab mit Standardverfahren hergestellt werden. The glass according to the invention can be used on an industrial scale Standard procedures are made.
In einer bevorzugten Ausführungsform enthält das Glas 30-60 Gew-% SiO2, 2-40 Gew-% Na2O, 5-40 Gew-% CaO, 1-15 Gew-% P2O5 sowie XJy > 100 ppm, wobei X, Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba, Ag, Zn und y = 1 oder y = 2 ist.

To achieve a disinfectant effect, the amount XJ y is > 500 ppm, in particular> 1% by weight, particularly preferably> 2% by weight.
In der Nahrungsergänzung sowie bei Anwendung innerhalb des menschlichen Körpers sind Gehalte von XJy von 10 ppm bis 1 Gew-%, insbesondere 10 ppm bis 500 ppm, besonders bevorzugt Gehalte 10 ppm bis 250 ppm. In food supplements and when used within the human body, contents of XJ y are from 10 ppm to 1% by weight, in particular 10 ppm to 500 ppm, particularly preferably contents 10 ppm to 250 ppm.

Daher sind die Gläser vorteilhafterweise für Mahlungen in unterschiedlichen Mahlmedien, zum Beispiel Wasser, geeignet, d. h. das Glas weist eine hinreichende hydrolytische Beständigkeit auf. The glasses according to the invention can also be obtained in powder form and Products are added. Therefore, the glasses are advantageous for Grinding in different grinding media, for example water, is suitable, d. H. the glass has sufficient hydrolytic resistance.
Neben der Herstellung über ein Schmelzverfahren sind auch alternative Herstellungsverfahren über die Sol-Gel- oder Reaktionssinter-Route denkbar. In addition to manufacturing using a melting process, there are also alternatives Manufacturing process via the sol-gel or reaction sinter route conceivable.
