Definitions

  • the present invention relates to the use of triclosan for the protection of wood and wood-based materials against attack and / or destruction " by soft rot fungi, as well as new fungicidal " agents and new, synergistic mixtures based on the active ingredient triclosan, and their use for the protection of industrial materials from infestation , Damage and / or destruction by microorganisms.
  • the skilled person distinguishes between a structural destruction of the wood by Basidiomyceten and - if the wood is exposed to a high humidity or earth contact environment - by soft rot fungi, and a visual impairment of the wood by wood-discoloring fungi.
  • Tar oils Active ingredients for the protection of wood against the destruction by fungi have been known for a long time, for example, tar oils were used to protect the wood. Tar oils are characterized by good permeability and high leaching resistance, but have significant disadvantages due to their persistence, their odor and their toxicologically unfavorable properties, so that their use in wood preservation today is very limited.
  • active ingredients based on chromium, copper and arsenic salts have been used for permanent wood preservation, but these are subject to substitution pressure due to their toxicological and in particular ecotoxicological disadvantages.
  • triazole fungicides such as tebuconazole or propiconazole, may be mentioned by way of example.
  • wood preservatives for this hazard class still inorganic wood preservatives such as boron compounds, silicofluorides, chromium and fluorine-containing salts, chromium- and copper-containing salts with and without arsenic, chromium and copper-containing salts with and without boron compounds and betaine preparations based on polymeric betain in Combination with boron and copper salts, and highly water-soluble quaternary ammonium compounds used.
  • fungicides against Basidiomycete infestation today include triazole fungicides such as e.g. Tebuconazole, propiconazole or cyproconazole used. Furthermore, the fungicides IPBC, Cabendazim, Folpet as well as Dichlofluanid and Tolylfluanid are used for protection against wood-discolouring fungi. However, both the triazoles and the mentioned fungicides with activity against fungal trees in the test against soft rot fungi according to ENV 807 completely fail or have only an insufficient effect.
  • Triclosan belongs to the class of diphenyl ethers and is already used as a chemical disinfectant and preservative. Triclosan is used, among other things, as an additive in sports and functional textiles, shoes and carpets to prevent unpleasant odors. Further fields of application are the use of triclosan in toothpastes, cleaners, household sponges or plastic dishes as well as in cosmetics, shampoos, soaps, deodorants or lotions. In hospitals and medical practices, triclosan-containing solutions are used for disinfection.
  • Triclosan is characterized by a low acute toxicity, the LD50 value against rats (oral administration) is e.g. at 3700 - 4500 mg / kg. Triclosan is as a pure substance only moderately irritating, also there are no signs of sensitization or photosensitizing potential. Triclosan is an inhibitor of bacterial fatty acid biosynthesis. Triclosan is not used in wood preservation. This may be due to the fact that triclosan is degraded by wood-destroying basidiomycetes (see Hundt et al., Applied and Environmental Microbiology, September 2000, page 4157-4160, Vol. 66, No. 9).
  • triclosan has an excellent action against soft rot fungi.
  • the present invention thus relates to the use of triclosan (5-chloro-2- (2,4-dichlorophenoxy) phenol) for the protection of wood, wood-based materials and wood-plastic composites from infestation and / or destruction by soft rot fungi.
  • the use according to the invention substantially and decisively enriches the state of the art because ecotoxicologically hazardous heavy metal-containing wood preservatives protect wood with permanent soil contact or in environments with high humidity, i. For example, in hazard class 4, can be substituted. As a result, the environmental impact of heavy metals is significantly reduced.
  • Triclosan shows a broad activity against soft rot fungi such as. contrary to ENV 807 (Test method for the determination of the limit of activity against soft rot and others erdbe passende microorganisms, German version of 2001) described fungi such as Chaetomium globosum, Glenospora graphii, Humicola gisea, Petriella setifera, Trichurus spiralis and Lecythophora mutabilis and against Trichoderma viride, Stachybotrys cartarum, Chephaporium sp. and Acremonium sp ..
  • triclosan against soft rot can optionally be extended by adding at least one further microbicidal compound to increase the spectrum of action or to achieve special effects.
  • the activity spectrum can be supplemented by the addition of further fungicides and / or termiticides.
  • triazole fungicides examples include: azaconazoles, azocyclotin, bitertanol, bromuconazoles; Cyproconazole, diclobutrazole, difenoconazole, dinuconazole, epoxyconazole, etconazole, fenbuconazole, fenchlorazole, fenethanil, fluquinconazole, flusilazole, flutriafol, furconazole, hexaconazole, imibenconazole, ipconazole, izofos, myclobutanil, metconazole, paclobutrazole, penconazole, propiconazole, (+ / -) - cis-1- (4-chlorophenyl) -2- (1H-1,2,4-triazol-1-yl) cycloheptanol, 2- (1-tert-butyl) -1 - (2- chloroph
