ABSTRACT:
Dimensionally stable alkaline cleansing agents of low density consist at least of 2 to 50% by weight of alkali metal phosphates, 2 to 50% by weight of silicates and 1 to 60% by weight of alkali metal hydroxides and/or alkali metal carbonates or bicarbonates and additionally contain 0.25 to 10% by weight of phosphoric acid partial esters.
These cleansing agents are prepared by first foaming phosphoric acid partial esters with water in a weight ratio of (1:2) to (1:80), using intensive stirring. When the remaining components have been incorporated into the foam, using stirring or kneading, the resulting mixture is converted to moldings. The moldings are allowed to set for 0.5 to 15 hours.
