The invention relates to disinfectant compositions, containing (a) at least one amine and/or quaternary ammonium salt of the general formula (Ia) or (Ib) , wherein R1 represents C6-18 alkyl, R2 represents benzyl or C6-18 alkyl, R3 represents C1-18 alkyl or- [(CH2) 2-O] n R6, where n=1-20, R4 and R5 independently of one another represent C1-4 alkyl, R6 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; 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 inventive compositions are characterised 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.

L'invention concerne des compositions de désinfectants, contenant (a) au moins un amine et/ou sel d'ammonium quaternaire de formule générale (Ia) ou (Ib), dans lesquelles R<1> désigne alkyle C6-18, R<2> désigne benzyle ou alkyle C6-18, R<3> désigne alkyle C1-18 ou -[(CH2)2-O]<i>n</i>R<6> avec <i>n</i>=1-20, R<4> et R<5> désignent indépendamment alkyle C1-4, R<6> désigne hydrogène ou phényle éventuellement substitué et A<-> désigne un anion monovalent ou un équivalent d'un anion polyvalent d'un acide inorganique ou organique ; et b) au moins un alkanolamine de formule générale (II), dans laquelle m et, le cas échéant, o et p ont indépendamment la valeur 2 ou 3 et x et y ont indépendamment la valeur 0 ou 1, ou un sel correspondant ; le rapport de masse (I):(II) est de 20:1 à 1:20. Les compositions selon l'invention se caractérisent par un bon effet bactéricide et en particulier fongicide, même employées en faible concentration, et elles peuvent être utilisées aussi bien comme désinfectants que comme conservateurs.
