Abstract
Abstract A laundering detergent is a mull which contains at least one detergent builder; and a nonionic surfactant system with a low pour point, most preferably 5°C or below. Preferably the solids in the composition have a particle size in excess of 10 microns, and the viscosity lies in the range 10 4 to 10 5 centipoise. The detergent mull is delivered in a water soluble film pouch.
