Abstract (en)
[origin: WO2019144372A1] A detergent granule with a relatively high total anionic surfactant content, e.g., from 40% to 90% by total weight of such detergent granule, which includes a core and a coating layer thereover. The core contains one or more anionic surfactants and a non-quaternized alkoxylated polyethyleneimine having a polyalkyleneimine core with one or more alkoxy side chains bonded to at least one nitrogen atom in the polyalkyleneimine core. The coating layer contains silica. Such detergent granule can maintain satisfactory flowability, despite its high anionic surfactant content, thereby easier to process into finished granular detergent products.
