Disinfectant

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.

         where 
         R 2  is benzyl or C 6-18 -alkyl, 
         R 3  is C 1-18 -alkyl or —[(CH 2 ) 2 —O] n R 6  where n=1-20, 
         R 4  and R 5  independently of one another are C 1-4 -alkyl, 
         R 6  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 
         ii) at least one alkylamine of formula: 
       
       
         
           
           
               
               
           
         
         where m and, if present, o and p 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 (I):(II) of 20:1 to 1:20. 
       
     
     
         2 . The fungicidal disinfectant composition according to  claim 1 , wherein the quarternary ammonium salt is selected from the group consisting of didecyldimethyl-ammonium salts, dioctyldimethylammonium salts, octyldecyldimethylammonium salts, coconutalkyl-dimethylbenzylammonium salts and benzyldimethyloxoethylammonium salts and mixtures of these compounds. 
     
     
         3 . The fungicidal disinfectant composition according to  claim 1 , wherein the alkanolamine (II) is selected from the group consisting of monoethanolamine, diethanolamine, triethanolamine and 3-amino-1-propanol. 
     
     
         4 . The fungicidal disinfectant composition according to  claim 1 , wherein the mass ratio (I):(II) is between 1:5 and 5:1. 
     
     
         5 . The funcicidal disinfectant composition according to  claim 1 , wherein the disinfectant composition includes water as a solvent. 
     
     
         6 . The fungicidal disinfectant composition according to  claim 1 , wherein the disinfectant composition additionally comprises one or more aids selected from the group consisting of organic solvents, surfactants, complexing agents, fragrances and colorants. 
     
     
         7 .- 12 . (canceled) 
     
     
         13 . The fungicidal disinfectant composition according to  claim 2 , wherein the alkanolamine (II) is selected from the group consisting of monoethanolamine, diethanolamine, triethanolamine and 3-amino-1-propanol. 
     
     
         14 . The fungicidal disinfectant composition according to  claim 3 , wherein the mass ratio of (I):(II) is between 1:5 and 5:1. 
     
     
         15 . The fungicidal disinfectant composition according to  claim 4 , wherein the disinfectant composition includes water as solvent. 
     
     
         16 . The fungicidal disinfectant composition according to  claim 5 , wherein the disinfectant composition additionally comprises one or more aids selected from the group consisting of organic solvents, surfactants, complexing agents, fragrances and colorants.
