FABRIC SOFTENING DETERGENT ABSTRACT OF THE DISCLOSURE: A particulate synthetic organic fabric softening deter- gent composition product of improved appearance and/or flowabili- ty is made by mixing together 10 to 60% of detergent composition particles having finely divided bentonite powder adhered to external surfaces thereof and 90 to 40% of similar such detergent composition particles devoid of such bentonite powder on the surfaces thereof. When the detergent composi- tion particles, preferably spray dried, are white and the bentonite is off-color the described product appears whiter than does a "control" wherein the same total proportion of bentonite is agglomerated onto the surfaces of all the detergent particles. Also, when the bentonite-surfaced particles are higher in content of tacky detergent than the non-bentonite-surfaced particles, which increased detergent content may be obtained by spraying aqueous detergent solu- tion onto the particles before agglomeration with bentonite powder, the flow properties of the product are improved, compared to a product containing the same total proportion of the detergent evenly distributed throughout all the particles. The bentonite particles are adhered to the detergent composition particles with the aid of an aqueous spray, prefer- ably of a dilute sodium silicate solution, and the agglomerate resulting may be used directly as a detergent composition or may be blended with detergent composition particles not having bentonite on the surfaces thereof.
