Disinfectant

Abstract

Disinfectant compositions, containing (a) at least one amine and/or quaternary ammonium salt of the general formula (Ia) or (Ib): wherein R 1 represents C 6-18 alkyl, R 2 represents benzyl or C 6-18 alkyl, R 3 represents C 1-18 alkyl or —[CH 2 ) 2 —O] n R 6 , where n is 1 to 20, R 4 and R 5 independently of one another represent C 1-4 alkyl, R 6 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. 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.

1 . A disinfectant composition comprising: 
 (i) a quaternary ammonium salt of formula:                          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 alkanolamine 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 disinfectant composition according to  claim 1 , wherein the quarternary ammonium salt is selected from the group consisting of didecyldimethylammonium salts, dioctyldimethylammonium salts, octyldecyldimethylammonium salts, coconutalkyldimethylbenzylammonium salts and benzyldimethyloxoethylammonium salts and mixtures of these compounds.  
     
     
         3 . The disinfectant compostion 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 disinfectant composition according to  claim 1 , wherein the mass ratio (I):(II) is between 1:5 and 5:1.  
     
     
         5 . The disinfectant composition according to  claim 1 , wherein the disinfectant composition includes water as a solvent.  
     
     
         6 . The 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 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 disinfectant composition according to  claim 3 , wherein the mass ratio (I): (II) is between 1:5 and 5:1.  
     
     
         15 . The disinfectant composition according to  claim 4 , wherein the disinfectant composition includes water as solvent.  
     
     
         16 . The 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.
