Stable aqueous suspension of water-insoluble, calcium-binding aluminosilicates and nonionic suspending agents |
摘要 |
Aqueous suspensions of water-insoluble, calcium-binding aluminosilicates with an improved stability against settling comprising at least 20% by weight of at least one finely-divided, water-insoluble silicate compound having a calcium-binding power of at least 50 mg CaO/gm of anhydrous active substance and having the formula, combined water not shown (M2/nO)x .Me2O3.(SiO2)y where M is a cation of the valence n, exchangeable with calcium, x is a number of from 0.7 to 1.5, Me is aluminum or boron, and y is a number from 0.8 to 6, and at least 0.5% by weight of a practically water-insoluble nonionic aliphatic surface-active compound having a turbidity point of a 1% solution in water of below room temperature, and the remainder an aqueous liquor. The said suspensions are pumpable and suitable as stock solution in the preparation of washing agent compositions.
