ABSTRACT:
A liquid heavy duty laundry detergent composition comprising a suspension of builder salt in liquid nonionic surfactant in which the stability against settling of the composition is improved by the addition of small amounts of urea. The yield stress of the compositions can be improved with the same or lower plastic viscosity, especially at low concentrations of the urea. The addition of small amounts of urea also improves the dispersibility of the suspension of builder salt when the composition is added to water.
