摘要
Spray dried detergent compositions which incorporate a sodium aluminosilicate detergency builder, are prepared by forming an aqueous detergent slurry containing the sodium aluminosilicate and then admixing an aqueous solution or suspension of sodium silicate with the detergent slurry at a point between the slurry mixing vessel and the spray nozzle. This avoids harmful interaction between the sodium aluminosilicate and the sodium silicate, which otherwise decreases washing performance, while retaining good powder properties.
