Laundry detergent compositions having enhanced greasy and oily soil removal performance

Laundry detergent compositions containing no phosphate or low levels of phosphate materials and specific mixtures of selected nonionic surfactants and selected cationic surfactants are disclosed. The nonionic/cationic surfactant mixtures are formulated to have "cloud point" characteristics and, preferably, reduced cationic monomer concentrations as defined herein. These compositions are unusually effective in removing greasy and oily soils and body soils from fabrics; they are also effective in the removal of particulate soils. A process is disclosed for laundering fabrics using compositions containing nonionic surfactants and cationic surfactants.
