Abstract (en)
[origin: EP0294694A2] Aqueous pumpable, stable suspensions of a silicate which is insoluble in water and is able to bind calcium ions contain, based on the total weight of the aqueous suspension, a) as silicate able to bind calcium 0.5 to 80 % by weight of a finely divided synthetic compound which contains bound water, is insoluble in water and has the general formula (cat2/nO)x.Me2O3.(SiO2)y (I), where cat is a cation of valency n which can be replaced by calcium, x is a number from 0.7 to 1.5, Me is boron or aluminium and y is a number from 0.8 to 6, and b) as dispersing ingredient 0.5 to 6 % by weight of a mixture of at least two oxo alcohol ethoxylates of the formula II R-(OCH2CH2)n-OH, where R is C10-C15-alkyl with a maximum degree of branching of 25 %, i.e. a maximum of 25 % of the fatty alcohol ethoxylate have a single methyl branch, n = 3 - 5.5 mol of EO in component 1 n = 5.75 - 7 mol of EO in component 2, and can be used to produce detergents and cleaners in powder form.
