Abstract (en)
[origin: WO02062933A1] A process for the preparation of a disintegrant, suitable for use in a composition in the form of a moulded body, comprises forming by a dry granulation process a granular composition comprising a swelling clay and a water insoluble inorganic material. Preferably, the granular composition also comprises a water-swellable material. The invention also makes available a composition suitable for use as a disintegrant in a composition in the form of a moulded body, said composition being in the form of granules comprising a swelling clay, a water insoluble inorganic material and a water-swellable agent which, in its anhydrous state, comprises no more than 20 per cent of the combined weight of said swelling clay, said water insoluble inorganic material and said water-swellable agent.
