Abstract
Abstract Fabric conditioning particles comprising a hydrogenated castor oil and a fatty quaternary ammonium salt. These particles are suitable for incorporation into detergent compositions, and adhere to fabric laundered in such compositions. When the laundered fabrics are heated in a clothes dryer, the particles melt and spread uniformly on the fabrics, thus providing a fabric conditioning coating.
