The speed of disintegration of tablets containing a water-softening agent, especially water-insoluble, water-softening agent intended as detergency builder for fabric washing is enhanced by incorporating sodium acetate trihydrate, potassium acetate or a mixture thereof. To inhibit caking and facilitate handling during manufacture, smaller particles of another substance are preferably provided at the surface of the crystals of the acetate or citrate.
