Abstract
Lecithin or certain other phosphate esters are added to a non-aqueous liquid heavy duty laundry detergent composition in the form of a suspension of builder salt in liquid nonionic surfactant containing small amounts of low density filler, such as hollow plastic or glass microspheres to provide stabilization against phase separation and further containing a small amount of organophilic modified clay, such as a water-swellable smectite clay, in which the metal cations are totally or partially exchanged with mono- or di-long chain quaternary ammonium compound to provide a viscoelastic network structure. The lecithin reduces plastic viscosity and helps maintain the viscoelastic network structure over extended periods of time.
