ABSTRACT OF THE DISCLOSURE: A process for manufacturing a high bulk density particulate detergent composition, of a bulk density greater than 0.7 g./cc. and preferably in the range of 0.8 to 1.0 g./cc., includes turbodrying a mixture of synthetic anionic organic detergent, preferably of sodium C12-13 linear alkyl benzene sulfonate, water, and fabric softening bentonite, in which turbodrying process the mixture is repeatedly subjected to centrifugal and axial forces which create thin films of the mixture, which are pulled apart, due to such forces, to form particles, which are further turbodried and thereby converted to high bulk density particles of substan- tially globular shape and desired particle sizes. In a preferred embodiment of the invention the mixture charged to the turbodryer is made by turbomixing an aqueous solution, dispersion or paste of anionic detergent with bentonite, and the mixture made thereby is directly turbodried. Also described are combined turbomixing and turbo- drying apparatuses, and products of the invented processes.
