Abstract: In the process for the preparation of dicalcium phosphate dihydrate having good fluoride (fluorine) compatibility and hydrolytic stability, which effects further thickening which is as low as possible when it is used in toothpastes, by reaction of calcium carbonate suspended in water with an aqueous solution of orthophosphoric acid, precipitation of dimagnesium phosphate trihydrate as stabiliser by reaction of aqueous solutions of a magnesium salt and of orthophosphoric acid in the presence of a basic compound, and also subsequent filtration, drying and milling of the precipitate, there is added to the reaction mixture as further stabiliser from 0.2 to 0.8 % by weight of polyphosphoric acid, calculated on the basis of the dicalcium phosphate dihydrate precipitated in the reaction mixture.

Abstract: A detergent containing 5 to 50% by weight of at least one surfactant, 0.5 to 60% by weight of a matrix substance and also standard laundry aids, contains as matrix substance an amorphous, low-water sodium disilicate having a water content of 0.3 to 6% by weight which has preferably been produced by partial dehydration of commercially available powdered amorphous sodium disilicate having a water content of 15 to 23% by weight.
