BUILT DETERGENT COMPOSITONS CONTAINING STABILIZING AGENTS

摘要

A liquid heavy duty laundry detergent composition comprises a suspension of builder salt in liquid nonionic surfactant in which the stability against settling of the composition is increased by the addition of small amounts of a urea additive or a higher alkyl quarternary 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 urea additive or the alkyl quarternary ammonium surface active agent. The addition of small amounts of urea also increases the dispersibility of the suspension of builder salt when the composition is added to water.
