A particulate alkaline detergent with unexpectantly good bleaching performance and with reduced phosphorus content contains 5-40% detergent active, 12.5-25% tripolyphosphate, 7.0-36% aluminosilicate builder such as zeolite, 5-30% peroxybleach such as sodium perborate and 0.1 to 15% activator such as TAED, the perborate to TAED ratio being between 2:1 and 15:1. The detergent active may be anionic material or a mixture of an anionic material and a minor amount of nonionic material. The compositions are particularly suitable for containing fluorescers and show surprisingly improved bleaching performance as water hardness increases. |
