Abstract
Solid laundry softening compositions and applications of use are disclosed. Solid laundry softening compositions combine quaternary ammonium compounds with an inorganic carrier to provide a flowable powder for solidification in a pressed or extruded solid composition. A high loading of quaternary ammonium compound in the inorganic carrier, including an inorganic salt, can be further combined with softening boosters, processing aids, surfactants, and/or additional functional ingredients to provide stable solid compositions.
