WAFERRIGE STABILE SUSPENSION WATERUNLOESLICHER FOR BINDING CALCIUMIONES OF ACCESSIBLE SILICates OF THEIR USE AND PREPARATION OF PHOSPHATE SUBSTITUTES FOR WASHING AND CLEANING AGENTS AND PHOSPHATE SUBSTITUTES

摘要

1. Pumpable stable aqueous suspensions of a water-insoluable silicate capable of binding calcium ions in the form of a finely divided bound water-containing synthetically produced water-insoluble compound corresponding to the general formula (Cat2/n O)x . Me2 O3 . (SiO2 )y (I), in which Cat represents a cation which is exchangeable with calcium of valency n x represents a number from 0.7 to 1.5, Me represents boron or aluminium, and y represents a number from 0.8 to 6, characterised in that contains the water-insoluble silicate capable of binding calcium ions in quantities of at least 0.5% by weight and as constituent having a dispersing effect, from 0.5 to 6% by weight of a mixture of at least two different alkylphenol ethoxylates corresponding to the formula see diagramm : EP0144492,P9,F2 wherein in Formula II R=an aliphatic radical containing from 1 to 15 carbon atoms and n represents from 2 to 7 preferably from 4 to 6, in particular 5 in one alkylphenol ethoxylate used in the mixture and from 8 to 15, preferably from 8 to 12, in particular 9 or 10 in the other alkylphenol ethoxylate and a content which is dissolved in the aqueous phase of from 4 to 25% by weight of the trisodium salt of nitrilotriacetic acid, with respect to the suspension, on the condition that the suspension contains at least 20% by weight of water.
