Definitions
- the invention relates to an antimicrobial, anti-inflammatory, wound-healing and disinfecting glass and a glass powder comprising such a glass.
- DE 39 39 831 shows a crystallized glass or a glass ceramic and in particular a biocompatible glass or a biocompatible glass ceramic which can be used to repair a damaged or destroyed part of a tooth.
- DE 39 39 831 provides for the use of a colorant, such as a precious metal halide. The halides are not described in detail.
- the object of the invention is to provide an antimicrobial, anti-inflammatory and disinfectant glass which itself has anti-microbial and anti-inflammatory effects and which uses the disinfectant effect of iodide in the glass synergistically.
- Iodine or " iodide has an antimicrobial effect, which has been used in the medical field for a long time.
- An iodine tincture is a clear, brown-red liquid which consists of 2.5 parts of iodine, 2.5 parts of potassium iodide, 28, 5 parts of water and 66.5 parts of alcohol (90%).
- this invention is excellently suitable for food supplements. Glasses doped higher with iodide show a clear antimicrobial effect as well as disinfectant and anti-inflammatory or wound-healing properties, whereby this effect synergistically exceeds the individual effects of the glass and the iodide ions.
- the glass contains Si0 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 will increases significantly, so that the melting and hot-forming properties deteriorate.
- N ⁇ g O is used as a flux when melting the glass.
- the melting behavior is negatively influenced at total concentrations of less than 5%.
- the necessary mechanism of ion exchange is no longer sufficient to achieve an antibacterial effect.
- 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.
- P 2 0 5 is a network former and can increase the crystallization stability.
- concentrations should not be above 15% by weight, otherwise the chemical resistance of the silicate glass will decrease too much.
- P, O s improves the surface reactivity of the glasses.
- B 2 0 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 improves the chemical resistance especially in the slightly alkaline range and is therefore necessary to prevent the glass from dissolving in aqueous media. It also contributes to the ion exchange with H +.
- MgO improves the chemical resistance especially in the slightly alkaline range and is therefore necessary to prevent the glass from dissolving in aqueous media. It also contributes to the ion exchange with H +. K J OT and Li 2 0 additions favor the interchangeability of sodium and potassium, and lithium itself can be exchanged for H honing.
- the amount of Al 2 0 3 can be added to increase the crystallization stability up to a maximum of 10% by weight.
- Fluoride can be added with iodide to achieve synergistic enhancement.
- the glass according to the invention can be produced on an industrial scale using standard processes.
- the amount XJ y is > 500 ppm, in particular> 1% by weight, particularly preferably> 2 % by weight.
- 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.
- the glasses according to the invention can also be obtained in powder form and added to products. Therefore, the glasses are advantageous for Grinding in different grinding media, for example water, is suitable, ie the glass has sufficient hydrolytic resistance.
- Particle sizes of ⁇ 100 ⁇ m can be obtained by a grinding process. Particle sizes of ⁇ 50 ⁇ m or 20 ⁇ m have proven to be expedient. Particle sizes ⁇ 10 ⁇ m and smaller than 5 ⁇ m are particularly suitable. Particle sizes ⁇ 1 ⁇ m have proven to be particularly suitable
- Mahi process can be carried out dry as well as with aqueous and non-aqueous Mahi media.
- the glasses within the claimed composition range meet all requirements regarding use in the areas of paper hygiene, cosmetics, paints, varnishes, cleaning, medical products, cosmetic applications, food additives and use in deodorants such as deodorants and antiperspirants.
- the glass can be used in any suitable form, including the powder form mentioned. Mixtures of different glass memevers from the composition range with different compositions are also possible. Mixing with other glass powders is also possible to combine certain effects.
- the invention will be described below with reference to exemplary embodiments.
- Table 1 shows compositions (synthesis values) [% by weight] and properties of glasses according to the invention.
- the antimicrobial, anti-inflammatory, wound healing and disinfectant glasses or glass powder can be used as a food additive, in cosmetic products, deoproducts, in medical products, plastics and polymers, paper hygiene, in paints, varnishes and cleaning and cleaning agents.
