Abstract
A non-aqueous liquid heavy duty laundry detergent composition in the form of a suspension of builder salt in liquid nonionic surfactant is stabilized against phase separation by the incorportation of a small amount of a vicinal-hydroxy compound. A low density filler to equalize the densities of the continuous liquid phase and the dispersed phase may be used in conjunction with the vicinal-hydroxy compound.
