The formula according to  example N as well as 72.22 wt.% of ethanol and 3.79 wt.%  of 2-propanol as the alcoholic main component also contains  acidic compounds in the form of 1.34 wt. % of L(  +  )-lactic  acid and 0.66 wt. % of glycolic acid. In addition, it contains  PEG 4000 as an additive for regulating the material consis- tency, glycerin as a skin care component, sodium pyrrolidon- ecarboxylate (Na PCA) and water. However, example N con- tains neither urea nor a zinc salt.  [0119]  Example O as well as 72.22 wt. % of ethanol and  3.79 wt.% of 2-propanol as the alcoholic main component  contains 4.00 wt.% of urea and PEG 4000 as an additive for  regulating the material consistency and water. However,  example O contains essentially no acidic compound and no  zinc salt.  [0120]  Example P essentially has the same composition as  example  0,  wherein instead of the urea in example P 1.10 wt.  % of organic zinc salt or Zn PCA is present. The formula  according to example P contains neither an acidic compound  nor urea.  [0121]  The maximal viral titer reduction after 120 seconds  which is attainable with the formulae of examples N-P is  about 3.69 log stages. Hence even with a long exposure time  of 120 seconds none of the comparative examples N-P  reaches a viral titer reduction by 4 log stages. Although the  formulae according to examples N-P have good skin taler- ance, they must be classified as scarcely suitable for use on  account of their limited virucidal action.
