Abstract:
1. A formulation, comprising: (A) at least one aminocarboxylate, selected from the group consisting of methylglycine diacetate (MGDA), iminodisuccinic acid (IDA), glutaminic acid diacetate (GLDA), and a salt thereof, (B) at least one alkyleneimine polymer which is covalently modified with at least one carboxylic acid or at least one derivative of a carboxylic acid or at least one derivative of carbonic acid, where up to at most 75 mol % of the nitrogen atoms of the primary and secondary amino groups of the alkyleneimine polymer have been reacted with carboxylic acid or derivative of carboxylic acid or carbonic acid, wherein the at least one covalently modified alkyleneimine polymer (B) is at least one member selected from the group consisting of: (B1) an alkyeneimine polymer that has been reacted with at least one ethylenically unsaturated C (B2) an alkyeneimine polymer that has been reacted with at least one C (B3) an alkyeneimine polymer that has been reacted with at least one carbonic acid ester, and (B4) an alkyeneimine polymer that has been reacted with hydrocyanic acid and formaldehyde.
