Abstract (en)
[origin: WO03104370A1] The invention relates to an automatic dishwashing detergent or an automatic dishwashing auxiliary agent. Said agents contain at least one zinc salt, in addition to at least one crystalline multi-layer silicate of general formula (I) a A20 b BO c C203 d D205 x Si02 y H20 (I), in which A represents an alkali metal and/or hydrogen, B represents an earth alkaline metal and/or a subgroup element, preferably an element from the group zink, iron, manganese, C represents an element of the third main group of the periodic table and/or a subgroup element, preferably iron, and D represents an element of the fifth main group of the periodic table and/or a subgroup element and the following applies 0 </= a </= 1; 0 </= b </= 0.5; 0 </= c/x </= 0.05; 0 </= d/x </= 0.25; 1.9 </= x </= 22; 0 </= f </= 40. Said agents are characterised by significantly improved glass anti-corrosion properties.
