| Title of Invention | A NON-SPRAY-DRIED GRANULAR COMPONENT FOR USE IN LAUNDRY DETERGENT |
|---|---|
| Abstract | A non-spray-dried granular component suitable for use in a particulate zero-phosphate laundry detergent composition comprises from 10 to 30 wt % of organic surfactant and from 20 to 50 wt % of zeolite MAP, the component having a bulk density not exceeding 700 g/l. The component may be prepared by a mixing and agglomeration process using a high-speed mixer, a moderate- or low-speed mixer, and a gas fluidisation granulator. The component may be used in conjunction with a spray-dried granular component of lower bulk density, for example, a spray-dried detergent base powder containing organic surfactant and zeolite A, or a spray-dried sodium-carbonate-based adjunct. |
