Aluminosilicates in the form of P type zeolites are used as detergency builders and have a silicon to aluminium ratio not greater than 1.33, preferably above 0.9. These zeolites will usually have a calcium binding capacity of at least 150 mg CaO per gram of anhydrous aluminosilicate. A preferred form of the zeolite P has a silicon to aluminium ratio up to 1.15, and preferably above 0.9, with a tetragonally distorted cubic crystal structure. A process of the preparation of these zeolite P builders is described.
