Abstract
A particulate agglomerate of cationic/anionic surfactant complex and bentonite is provided, for addition to the wash water in the wash cycle operation of automatic washing machines, to make washed and dried laundry softer to the touch and static-free, after rinsing and automatic tumble drying. Among the various advantages of the invention are increased stability of the cationic/anionic surfactant complex in such agglomerate form and during storage before use, the fabric softening effect of the betonite, and the ready dispersion of the complex in the wash water, so that it does not deposit on the laundry as greasy stains of the type that are obtained when a sufficient antistatic and fabric softening proportion of cationic surfactant or an antistatic and fabric softening proportion of an essentially pure cationic/anionic surfactant complex is added to a control wash in which the wash water contains a detersive proportion of synthetic organic anionic detergent. Also within the invention are processes for manufacturing the described agglomerate and for employing it together with a built synthetic organic anionic detergent composition in the washing machine to simultaneously wash and treat the laundry to make it soft and static-free.
