Definitions

  • the present invention relates to storage-stable, synergistic combinations containing glutaric dialdehyde (GDA) and 2-methyl-2H-isothiazol-3-one (methylisothiazolinone, MIT) and optionally 2-bromo-2-nitropropane-l, 3-diol (Bronopol) and / or other active substances for the protection of technical materials.
  • GDA glutaric dialdehyde
  • MIT 2-methyl-2H-isothiazol-3-one
  • Bronopol 2-bromo-2-nitropropane-l, 3-diol
  • GDA has been known as an antimicrobial compound since the 1960's (Gorman, SP, Scott, EM and Russel, AD, 1980. Antibacterial activity, uses and mechanism of action of glutaraldehyde, J. Appl. Bacteriol, 48, 161-90. ).
  • GDA is used as a 2 to 50% by weight solution adjusted to a pH ⁇ 7. At pH values above 7, GDA shows an increasingly pronounced tendency to polymerise, but also the so-called "fast killing" effect, which is why GDA is often used as a disinfectant and sterilizer, or slimicides, as a preservative becomes.
  • MIT is usually treated with other, fast-acting isothiazolinones such as e.g. 5-chloro-2-methyl-4-isothiazolin-3-one (chloromethylisothiazolinone, CMIT) or further combined with bronopol.
  • isothiazolinones such as e.g. 5-chloro-2-methyl-4-isothiazolin-3-one (chloromethylisothiazolinone, CMIT) or further combined with bronopol.
  • Microbicidal mixtures containing GDA and CMIT and MIT are already known and are used for the preservation of technical materials.
  • DE 3313689 describes mixtures comprising GDA and CMIT and MIT, which are used for the antimicrobial treatment of cooling water systems and process waters in papermaking.
  • KR 2000015319 A describes synergistic mixtures containing GDA and CMIT and MIT for use in papermaking and for the preservation of process water.
  • JP 2002 370906 A describes mixtures comprising GDA and MIT in the ratio of 1: 1 and synergistic mixtures comprising GDA, MIT and o-phthalaidehyde.
  • the abovementioned mixtures according to the prior art have in common that they have a very low storage stability due to the formation of decomposition products, which severely restricts the technical applicability or does not fully develop the desired effect.
  • JP 03112908 describes stabilized microbicidal solutions containing GDA as well as CMIT and MIT as magnesium complex as well as polyglycols. ⁇ EP2008 / 064095
  • JP 05271015 describes mixtures containing GDA and clathrates of CMIT and MIT with 1, 1, 6,6-tetraphenyl-2,4-hexadyn-l, 6-diol.
  • Agents comprising GDA, MIT and optionally CMIT, wherein the CMIT content is 0 to 4% based on the weight ratio of CMIT to MIT and the weight ratio of GDA to MIT at least 1.1: 1, preferably 1.5: 1 to 50: 1 is more preferably 2: 1 to 20: 1 and most preferably 4: 1 to 20: 1.
  • compositions according to the invention are characterized in that they are highly effective as microbicidal agents and are particularly storage-stable.
