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 R 1 is C 6-8 -alkyl, 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 (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.
