ABSTRACT:
Fabric softener particles comprising an inner core of fabric softening composition and an outer coating completely surrounding said core. The outer coating is substantially water-insoluble and protects the inner core from dissolving when present in a typical fabric laundering operation, but releases the softener composition to the fabrics when the fabrics are dried in a heated dryer. The particles contain water-insoluble particulate materials, e.g., silica particles, having a diameter of greater than about one micron to reduce the shiny appearance of visible softener spots which occasionally are present on fabrics treated with said fabric softener particles and to maintain a relatively constant viscosity.
