ABSTRACT OF THE DISCLOSURE: Agglomerated particles of finely divided fabric softening bentonite and sodium sulfate particles have been found to possess improved fabric softening properties, compared to agglomerated bentonite, especially when employed in the hand washing of laundry which is subsequently line dried. Such agglomerates are also of excellent particle strength and are readily dispersible in water. The described product may be made by agglomerating finely divided bentonite and sodium sulfate powders with the aid of excess moisture, after which the agglomerated particles resulting are dried and those of desired size, preferably in the No's. 30 to 100 sieve size range (U.S.), axe obtained. The fabric softening agglomerate made may be mixed with spray dried synthetic organic anionic detergent composition beads of about the same or higher bulkdensity, preferably in the 0.3 to 0.5 g./cc. range, with about 5 to 30% of the agglomerate particles being present, to make a non-segregating fabric softening particulate detergent composition of improved softening properties.
