         4 . Disinfectant according to one of the preceding claims, characterized in that the aryloxyalkanol is phenoxyethanol or phenoxypropanol.  
     
     
         5 . Disinfectant according to one of the preceding claims, characterized in that the arylalkanol is 3-phenylpropan-1-ol, phenylethyl alcohol, veratryl alcohol, benzyl alcohol or 2-methyl-1-phenyl-2-propanol.  
     
     
         6 . Disinfectant in the form of a working mixture which comprises 
 (a) 0.05 to 0.2% by weight of 1-(2-ethylhexyl) glycerol ether and    (b) 1.0 to 2.0% by weight of phenoxyethanol.    
     
     
         7 . Disinfectant according to one of the preceding claims, characterized in that, in addition, it comprises water, ethanol and/or H 2 O 2 .  
     
     
         8 . Use of a disinfectant which comprises (a) one or more 1- or 2-(C 3 - to C 24 -alkyl) glycerol ethers and (b) one or more aromatic alcohols for controlling mycobacteria.  
     
     
         9 . Use according to  claim 8 , characterized in that the mycobacterium is selected from the group consisting of  Mycobacterium leprae, Mycobacterium tuberculosis  and  Mycobacterium terrae.    
     
     
         10 . Use according to  claim 8  or  9 , characterized in that a disinfectant according to one of  claims 1  to  7  is used.  
     
     
         11 . Process for controlling mycobacteria in which a disinfectant which comprises (a) one or more 1- or 2-(C 3 - to C 24 -alkyl) glycerol ethers and (b) one or more aromatic alcohols is allowed to act on the surface to be disinfected.  
     
     
         12 . Process according to  claim 11 , characterized in that the surface to be disinfected is a medical instrument or laboratory apparatus or a biological surface, in particular skin, mucosal membrane, wounds, plants or plant parts.
