Abstract: A process is provided in which selected modified polyamines are incorporated into fully formulated detergent compositions in a manner that unexpectedly results in enhanced cleaning performance. The process involves premixing the modified polyamine with a detersive surfactant or acid precursor thereof, and thereafter, adding adjunct ingredients such as builders and water. The entire mixture is then spray dried to form spray-dried granular detergent composition.
