CONTINUOUS PROCESS FOR MAKING A LAUNDRY DETERGENT COMPOSITION

摘要

The present invention relates to a continuous process for making a solid particulate laundry detergent composition comprising the steps of: (a) forming a soft surfactant particle having a cake strength of from about 30N to about 200N; and (b) contacting said soft surfactant particle with a free-flowing heterogeneous particulate mixture comprising multiple chemically distinct detergent particle populations, wherein said free-flowing heterogeneous particulate mixture has a cake strength of from about 0N to about 20N, wherein said free-flowing heterogeneous particulate mixture has a weight average particle size of from about 50 micrometers to 2000 micrometers, and wherein the ratio of (i) the cake strength of the soft surfactant particle in N to (ii) the time between step (a) and step (b) in minutes is in the range of from 6Nmin-1 to 2000Nmin-1.
