Abstract
Abstract Fabric softening compositions with improved conditioning properties comprising a cation-active fabric softener and certain substantially water-insoluble particulate materials are described. The compositions permit the simultaneous attainment of softening, ease of ironing, anti-wrinkling and appearance benefits of fabrics treated therewith.
