GRANULAR DETERGENT COMPOSITIONS COMPRISING NONIONIC SURFACTANT AND PROCESS FOR MAKING SUCH COMPOSITIONS

摘要

In a first aspect, the present invention concerns a granular detergent composition or component having a bulk density of at least 650 g/l, comprising a surfactant system wherein said composition or component comprises from 35 % to 85 % by weight of nonionic surfactant and wherein said surfactant system is substantially in the solid phase at temperatures of 25.degree.C and below, and that said surfactant system has a softening point above 25.degree.C and wherein the surfactant system has a viscosity profile whereby the viscosity of the surfactant system is at least 20000 cps at a temperature of 10.degree.C above the softening point, and less than 10000 cps at a temperature of 30.degree.C above the softening point, all viscosities being measured at a shear rate of 25s-1. In a second aspect the present invention concerns specific combinations of the nonionic surfactant containing particles with other detergent components to produce a finished laundry detergent composition. In a third aspect, the present invention concerns a process for the manufacture of nonionic surfactant containing particles of the present invention.
