Aqueous formulation, use an aqueous formulation, and process to manufacture a formulation.

摘要

Aqueous formulations comprising (a) at least o n e selected organic complexing agent of (a1) alkaline metal salts of aminopolicarboxylic acids and (a2) polymers carrying at least two units of -ch2 -n (ch2cooh)- per molecule,Partly or completely neutralised with alkalis,(b) at least one salt of at least one of the following acids: nitric acid,Sulfuric acid,Sulphic acid,Methanesulfonic acid,Carboxylic acids C1 -c2,Hydroxy -monocarboxylic acid C2 -c4,Dicarboxylic acids C2 -c7,Not replaced or replaced by hydroxyl,And tricarboxylic acids C4 -c6,Each of which has not been replaced or replaced by hydroxyl,(c) at least one selected compound of (c1) monoalkyl C2 -c10 from the esters of phosphoric acid,(c2) an alkinol C3 -c10,Optionally alcoholic with one to ten alkoxide groups per hydroxyl group,And (c3) an alkinodiol C4 -c10,Optionally alcoholic with one to ten alkoxide groups per hydroxyl group,Those aqueous formulations with values of pH in the range of 7,5 to 10.
