Abstract: The invention provides novel low temperature detergent mull compositions comprising:A detergent composition which comprises (a) solid builder, (b) liquid surfactant and, optionally, (c) one or more adjuncts, in the form of a low-temperature wash water dispersible, phase stable mull whose solid phase consists essentially of particulate solid builder having an average particle size greater than 10 microns and whose liquid phase consists essentially of at least one non-ionic surfactant, wherein said liquid phase has a pour point of less than 75.degree. F., thereby rendering said mull readily dispersible in cold wash water, and wherein said mull is rendered phase stable by the presence thereby of (i) a weight percent amount of said particulate builder which exceeds the weight percent of said liquid nonionic surfactant, or (ii) 0.1% to 5% by weight of the mull of added water, or (iii) both.
