PCT No. PCT/EP91/00400 Sec. 371 Date Nov. 12, 1992 Sec. 102(e) Date Nov. 12, 1992 PCT Filed Mar. 4, 1991 PCT Pub. No. WO91/13965 PCT Pub. Date Sep. 19, 1991.An aqueous cleaning and disinfecting concentrate comprising A) at lease one reaction product of a) an N-substituted propylene diamine of formula I R1-NH-(CH2)3-NH2 (I) in which R1 is a C8-C18 alkyl group and b) glutamic acid or a glutamic acid derivative of formula II R2-O-CO-(CH2)2-CH(NH2)-COOH (II) in which R2 is hydrogen or a C1-C4 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; B) at least one of the following antimicrobially active compounds: i) a quaternary ammonium compound of formula III <IMAGE> (III) in which R3 and R4 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- is an anion; ii) a phenol; iii) a biguanide; (iv) a quaternary phosphonium compound of formula IV <IMAGE> (IV) in which R7, R8, R9 and R10 are each independently an alkyl, alkenyl, aryl, or alkaryl group having from 1 to 16 carbon atoms, and Y- is an anion; and C) at least one low foaming surfactant. The invention also relates to the diluted concentrates, and to the method of use of the diluted concentrates, especially for the disinfection of medical equipment.
