摘要： Process for making a detergent composition having at least 40 % by weight of surfactant and a bulk density of at least 650 g/l, the process comprising the single step of high shear mixing until granular at a temperature from ambient to 60 DEG C, a binder component comprising said surfactant and less than 20 % water, with a particulate solid component, of initial particle size from 0.1 to about 500 microns, said particulate solid component having at least about 15 % by weight of particles with a particle size of at least about 50 microns and a sufficient amount of smaller particles so that the average surface area of the particulate component is at least about 9 m /g as measured by the BET method, and wherein the binder maintains the mixture in a particulate state throughout the process.

摘要： Process for making a detergent composition having at least 40 % by weight of surfactant and a bulk density of at least 650 g/l, the process comprising the single step of high shear mixing until granular at a temperature from ambient to 60 °C, a binder component comprising said surfactant and less than 20 % water, with a particulate solid component, of initial particle size from 0.1 to about 500 microns, said particulate solid component having at least about 15 % by weight of particles with a particle size of at least about 50 microns and a sufficient amount of smaller particles so that the average surface area of the particulate component is at least about 9 m2/g as measured by the BET method, and wherein the binder maintains the mixture in a particulate state throughout the process.
