Abstract

An aqueous cleaning and disinfecting concentrate comprising PA1 A) at lease one reaction product of PA2 a) an N-substituted propylene diamine of formula I EQU R.sup.1 --NH--(CH.sub.2).sub.3 --NH.sub.2 (I) PA2 in which R.sup.1 is a C.sub.8 -C.sub.18 alkyl group and PA2 b) glutamic acid or a glutamic acid derivative of formula II EQU R.sub.2 --O--CO--(CH.sub.2).sub.2 --CH(NH.sub.2)--COOH (II) PA2 in which R.sup.2 is hydrogen or a C.sub.1 -C.sub.4 alkyl group, wherein the said reaction product is optionally ethoxylated and/or propoxylated, and is optionally in the form of a salt with an organic or inorganic acid; PA1 B) at least one of the following antimicrobially active compounds: PA2 i) a quaternary ammonium compound of formula III ##STR1## in which R.sup.3 and R.sup.4 independently of one another represent alkyl radicals containing 1 to 3 carbon atoms or benzyl radicals, or halogenated or alkylated benzyl radicals containing 6 to 22 carbon atoms, and X.sup.- is an anion; PA2 ii) a phenol; PA2 iii) a biguanide; PA2 (iv) a quaternary phosphonium compound of formula IV ##STR2## in which R.sup.7, R.sup.8, R.sup.9 and R.sup.10 are each independently an alkyl, alkenyl, aryl, or alkaryl …
