Definitions
- the present invention relates to antimicrobial compositions containing silver in the form of metallic silver or as silver compound (s) and at least one further biocidal active substance selected from the class of isothiazolines and their use as preservatives and disinfectants.
- Biocides are used in a wide variety of applications to control or prevent the growth of microorganisms, thereby ensuring the preservation of products and materials. They are used in the building materials, textiles, leather, paper, electrical and food industries, but also in cosmetics, and agriculture. Likewise, biocidal active substances are used for preserving in paints and adhesives, water-in-oil emulsions and lubricants or for surface treatment. In order to achieve a broad spectrum of action of the preservatives against such different microorganisms, such as bacteria, fungi and molds, combination products of several biocidal active substances are usually used.
- the antimicrobial effect of silver and silver salts has long been known and is used for the antibacterial treatment of medical devices and aids, but also for the production of germ-resistant surfaces and textiles.
- the state of the art is to adsorb antimicrobial metals or metal compounds onto a carrier material in order to achieve a slow release of silver or silver ions and to achieve a long-lasting antimicrobial effect.
- EP-AO 116 865 metal compounds are applied to zeolites and incorporated into polymers.
- EP-AO 190 504 discloses antimicrobial Compositions containing metallic silver adsorbed on hydratable or hydrated oxides.
- EP-A-0 251 783 and EP-A-0 734 651 describe silver compounds which are applied to water-insoluble, non-hydrated or hydrolyzable oxides and show good bactericidal and fungicidal activity. According to US Pat. No. 6,641,829, US Pat. No. 6,461,386, US Pat. No. 6,454,813 and US Pat. No. 6,444,726, these supported silver compounds are used to furnish textiles with an antimicrobial active substance, for the preservation of cosmetics or also used for the preservation of water-based polymer emulsions.
- the silver-containing compositions mentioned in the prior art do not sufficiently fulfill a spontaneous and at the same time a long-lasting antimicrobial effect in an environment which promotes the growth of microorganisms and lose their effect in an aggressive environment.
- Another problem is the instability of silver compounds, which leads to a darkening of the products within minutes under the influence of light.
- WO-A-01/00021 it is described that the biocidal effect of pyrithione or pyrithione complexes can be improved by silver, copper or zinc salts.
- the script uses AgCl and Ag 2 O. Information on the stability of the biocidal agent, also in terms of color stability are not found.
- biocidal active substances from the group of the haloalkynyls for example 3-iodo-2-propynylcarbamate
- metal ions for example silver ions.
- This decomposition reaction can be prevented or reduced by adding amines.
- the presence of amines is undesirable in many applications.
- aminic components such as. As triazines with silver to colored complexes and are therefore useless for many applications.
- antimicrobial compositions which, even at very low use concentrations, display their spontaneous and sustained action, are toxicologically and ecotoxicologically harmless and are color-stable over long periods of time.
- the object of the present invention was therefore to provide antimicrobial compositions which are active against microorganisms from the group of bacteria, molds, algae and yeasts, are stable in a wide temperature range with long storage times, in very low concentrations well in formulations and products can be incorporated, show in the final products no color changes, especially under the influence of light and are toxicologically and ecotoxicologically compatible.
- compositions comprising silver or one or more silver compounds on a support and at least one further antimicrobial active substance from the group of
- Isothiazolines are characterized by a high, spontaneous and also long-lasting efficiency against bacteria and fungi.
- the invention therefore antimicrobial compositions containing

- the silver or the silver compound is adsorbed on a water-insoluble, inert, non-hydratable or non-hydrated, oxidic carrier, and the silver and / or the silver compound (s), always calculated as elemental silver, are based on the weight of the carrier, in amounts of from 0.1% to 75% by weight.
- the preferred carrier is selected from titanium, magnesium, aluminum, silicon, calcium and barium oxide, calcium hydroxyapatite, chalk, natural ground or precipitated calcium carbonates, calcium magnesium carbonates, silicates, layered silicates, zeolites, clays or bentonites.
- the carrier is titanium oxide, which is present in one or more of the crystalline forms anatase, rutile and brookite. In likewise preferred embodiments, mixtures of the abovementioned carriers can be used.
- the carrier should have a particle size of less than 25 microns, preferably of ⁇ 5 microns, more preferably ⁇ 1 micron. In a further preferred embodiment, the carrier has a particle size ⁇ 120 nm, more preferably ⁇ 5 nm, in particular ⁇ 25 nm.
- the proportion by weight of silver or of the silver compound, based on the weight of the carrier is in the range from 0.1% by weight to 75% by weight, preferably from 5% by weight to 50% by weight, particularly preferably 10% by weight. -% to 30 wt .-%, calculated as elemental silver.
- the supported silver compounds used in the invention are prepared in the manner described in EP-AO 251 783 ways and are also available as commercial products (JMAC LP 10 ®, ® JMAC Composite PG, Clariant (Germany) GmbH) available.
- Supported silver can be prepared from supported silver compounds by reduction of the silver compounds to the metal.
- Isothiazolines (which in the following include their derivatives) are understood as meaning compounds according to the formula (I) or (II)
- substituents may be, for example, linear, branched or cyclic hydrocarbon groups, halogen atoms or carbonyl groups.
- hydrocarbon groups Cr to Ci 2 alkyl groups, phenyl groups and fused aromatic systems are preferred.
