| 摘要 |
The present invention provides a process for the manufacture of detergent tablets by granulation of organic surfactant and detergency builder to form granulated particles containing both surfactant and builder, with a water-soluble organic polymer which is solid at 25 DEG C incorporated into the particles during granulation, and, particles comprising one or more water soluble materials selected from either: compounds with a water-solubility exceeding 50 g/100g in water at 20 DEG C; or sodium tripolyphosphate, containing at least 50% of its own weight of the phase I anhydrous form, and which is partially hydrated so as to contain water of hydration in an amount which is at least 1% by weight of the sodium tripolyphosphate in the particles, are mixed with the granulated particles prior to compacting into tablets. Also provided is a tablet of compacted particulate detergent composition as described above. The tablets have good disintegration properties. |
