Abstract (en)
[origin: WO2022100995A1] The invention relates to dishwashing detergents that contain a metal complex of the general formula (I), (Aq+)p[Ms+Lm-](Xo-)r (I) wherein q is 1 or 2 and Aq+ represents a cation, selected from alkali metal cations with q = 1, ½ alkaline earth cations with q = 2 and ammonium ions with q = 1, Ms+ represents an aluminum ion, a transition metal ion or a lanthanoid metal ion, s is a number from 1 to 5, L represents a ligand of the formula (II), in which every R1 and R2 independently of each other is selected from H, unsubstituted or substituted, linear or branched C1-20 alkyl, unsubstituted or substituted, linear or branched C1-20 heteroalkyl, unsubstituted or substituted aryl, unsubstituted or substituted heteroaryl, unsubstituted or substituted, linear or branched C2-20 alkenyl, unsubstituted or substituted, linear or branched C2-20 heteroalkenyl and unsubstituted or substituted, linear or branched C2-20 alkinyl, unsubstituted or substituted, linear or branched alkylaryl, unsubstituted or substituted, linear or branched alkylaryl, unsubstituted or substituted, linear or branched alkylheteroaryl, every R3 independently from each other represents CH2COOH or CH2COO-, n is 0 or 1, Xo- represents an anion, selected from F-, Cl-, Br-, I-, OH-, HSO3 -, SO3 2-, SO4 2-, HSO4 -, NO2 -, NO3 -, PO4 3-, HPO4 2-, H2PO4 -, BF4 -, PF6 -, ClO4 -, acetate, citrate, formiate, glutarate, lactate, malate, malonate, oxalate, pyruvate, tartrate, methane sulfonate, methyl sulfate, p-toluene sulfate and succinate, m is a number from 0 to 5 and o is a number from 1 to 3, and p and r independently of each other represent a number from 0 to 6, with the proviso that the sum of s and the product of p and q is equal the sum of m and the product of r and o, and with the further proviso that the charge of formula (II) resulting from the residues R1, R2 and R3 is neutral or negative.
