Abstract
Abstract Detergent-compatible antistatic compositions are described containing a combination of cationic antistatic agents and hydrogenated triglycerides as discrete particles. Preferred compositions also include certain smectite clay materials to permit the simultaneous attainment of fabric softening, static-reduction and cleansing effects of fabrics washed therein.
