More Information
Summary:Detergents containing (a) 5 to 35 % of customary surfactants, (b) 10 to 40 % of microcrystalline zeolite, (c) 4 to 20 % of alkali metal silicates or carbonates and 0.1 to 5 % of (d1) aminoalkanephosphonates and/or (d2) copolymers of (meth)acrylic acid and maleic acid and (e) 5 - 80 % of other detergent ingredients are considerably improved in terms of their incrustation-preventing properties when they additionally contain (f) 0.05 to 1 % (based on free acid) of 1-hydroxyethane-1,1-diphosphonic acid in the form of the alkali metal salts. The ratio of (d1) to (f) is 3 : 1 to 1 : 6 and of (d2) to (f) is 40 : 1 to 2 : 1.
