Abstract
A process is provided for producing high-active detergent agglomerates through multi-stage surfactant paste injection. According to the process, starting detergent materials are mixed with an initial amount of surfactant paste and then allowed to age for a specified period of time. Following the initial paste injection and aging period, additional amounts of surfactant paste are injected incrementally to make a final detergent agglomerate having at least about 45% by weight of surfactant.
