  • Patent number: 8221733
    Abstract: Process for utilizing the disinfectant composition as a virucidal agent. The disinfectant composition includes: (a) an amine and/or quaternary ammonium salt of the general formula: where R1 is C6-8-alkyl, R2 is benzyl or C6-18-alkyl, R3 is C1-18-alkyl or —[(CH2)2—O]nR6 where n=1-20, R4 and R5 independently of one another are C1-4-alkyl, R6 is hydrogen or unsubstituted or substituted phenyl, and A? is a monovalent anion or one equivalent of a polyvalent anion of an inorganic or organic acid; and (b) at least one alkanolamine of the general formula: where n and, if present, m and o independently of one another have the value 2 or 3, and x and y independently of one another have the value 0 or 1, or a corresponding salt; in the mass ratio of (a) to ( )b) of 20:1 to 1:20.
    Type: Grant
    Filed: January 16, 2003
    Date of Patent: July 17, 2012

  • Publication number: 20100216890
    Abstract: Disinfectant compositions, containing (a) at least one amine and/or quaternary salt of the general formula (Ia) or (Ib), respectively, and (b) at least one alkanolamine of the general formula (II), or a corresponding salt. The mass ratio of the components in the formulas (I):(II) is between 20:1 and 1:20. The compositions are characterized by an excellent bactericidal and in particular fungicidal action even in small application concentrations and are suitable for use as both disinfectants and preservative agents.

  • Patent number: 6939840
    Abstract: Disinfectant compositions, containing (a) at least one amine and/or quaternary ammonium salt of the general formula (Ia) or (Ib): wherein R1 represents C6-18 alkyl, R2 represents benzyl or C6-18 alkyl, R3 represents C1-18 alkyl or —[CH2)2—O]nR6, where n=1-20, R4 and R5 independently of one another represent C1-4 alkyl, R6 represents hydrogen or optionally substituted phenyl and A? is a monovalent anion or the equivalent of a multivalent anion of an inorganic or organic acid; and (b) at least one alkanolamine of the general formula (II): wherein m and, if present, o and p independently of one another have the values 2 or 3 and x and y independently of one another have the values 0 or 1, or a corresponding salt. The mass ratio of the components in the formulas (I):(II) is between 20:1 and 1:20.

  • Patent number: 6610248
    Abstract: Disinfectants having N,N-bis(3-aminopropyl)octlyamine as the active substance. The disinfectants are characterized by good activity also against mycobacteria, low efficiency loss under protein load and little foaming. The disinfectants are particularly useful for disinfecting surfaces, containers and pipelines, for instance, in the food industry, and for disinfecting instruments, especially automatic instrument disinfection at low temperatures.
