The invention relates to compositions of a disinfectant agent containing a) at least one amine and/or quaternary ammonium salt of general formula (Ia) or (Ib), wherein R<1 >C6-18 represents alkyl, R<2 >represents benzyl or C6-18 alkyl; R<3 >C1-18 represents alkyl or -[(CH2)2-O)nR6 whereby n=1-20; R<4 >and R<5 >represent independently from each other C1-4 alkyl; R<6 >represents hydrogen or optionally substituted phenyl and A represents a monovalent anion or an equivalent multivalent anion of an inorganic or organic acid; and b) at least one guanidinium salt of formula (II), wherein X represents a monovalent anion or an equivalent multivalent anion of an organic or inorganic acid, in a mass ratio (I):(II) of 20:1-1:20. The inventive compositions are characterised in that they have a good bacterial and equally good fungicidal efficacy when used in low concentrations and can also be used as disinfectant agents as well as preservation agents. |
