15 Claims

1. A shaped detergent product comprising 10-100 wt. % of a solid amorphous phase and 0-90 wt. % of one or more other solid phases, said solid amorphous phase comprising:

25-88 wt. % free acid equivalent of aminopolycarboxylate;

10-60 wt. % free acid equivalent of an acid, said acid not being an aminopolycarboxylate;

6-30 wt. % water;

wherein the shaped detergent product contains at least 0.5 wt. % surfactant;

wherein the solid amorphous phase has a continuous volume of between 0.1 and 20 cm³; and

wherein the solid amorphous phase is prepared from an aqueous solution containing the aminopolycarboxylate, the acid, and at least 35 wt. % water by reducing the water content of the solution between 12 and 30 wt. % by boiling to produce a liquid desiccated mixture whilst keeping the liquid mixture at a temperature of at least 50 degrees Celsius, followed by cooling of the desiccated mixture to a temperature of less than 25 degrees Celsius to obtain the solid amorphous phase.
