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 a higher alkyl quaternary ammonium surface active agent. The yield stress of the compositions can be improved with the same or lower plastic viscosity, especially at low concentrations of the alkyl quaternary ammonium surface active agent.
