ABSTRACT OF THE DISCLOSURE: A particulate fabric softening composition and a partic- ulate fabric softening detergent composition are described, both of which include bentonite powder agglomerated into larger particulate bead or granule form with a normally solid co-melt of a penta- erythritol compound (PEC), such as pentaerythritol ditallowate (PEDT), and a nonionic surfactant, such as a condensation product of a mole of a C12-15 fatty alcohol with seven moles of ethylene oxide. The fabric softening composition described may be added to wash (or rinse water) but preferably is incorporated in a particulate built synthetic organic anionic and/or nonionic detergent composition to produce a fabric softening detergent composition. The invented detergent compositions are especially suitable for washing laundry in "cold" water, such as water at 40°C. or thereabout, in which the nonionic surfactant increases the dispersibility of the PEC, improves fabric softening activity thereof, in conjunction with the bentonite, and also prevents excessive whitening or chalking of dark colored laundry by the particulate fabric softening composition. These improved results have been attributed to the nonionic surfactant lowering the co-melt's melting point to about 40°C. or lower, at which temperature the softening composition disperses satisfactorily in the wash water. Additional advantages of the invention are a bonus effect of the nonionic surfactant in increasing detergency of the detergent composition and wash water, and in allowing a decrease in PEC content of the softening and detergent compositions without loss of softening effect.
